    CLINICAL COURSE and RELAPSE RATE IN INTESTINAL BEHCET'S DISEASE

    JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 2001
    TI Kim
    Behçet's disease is a multisystemic recurrent inflammatory disease. Gastrointestinal tract involvement in Behçet's disease has been identified throughout the alimentary tract and causes diverse symptoms. Various treatment have been utilized to induce or maintain remission. However, little is known about clinical course and prognosis in Behçet's disease with intestinal involvement. The aims of this study were to evaluate the clinical course and relapse rate in intestinal Behçet's disease and to investigate factors that may affect relapse. Methods, Clinical course and characteristics, including demographic parameters, gastrointestinal symptoms as well as systemic manifestations, laboratory data, endoscopic findings, and treatment strategies for the induction of remission, of 97 patients (49 male, 48 female) with intestinal Behçet's disease were retrospectively reviewed. Cumulative relapse free rate and factors related with relapse were analysed by Kaplan,Meier method and log,rank test, respectively. Results, The median duration of the relapse free period was 7 months (ranges from 1 to 171 months). One, two, and five year relapse free rates were 41.2, 29.7 and 10.2%, respectively. Sex, clinical subtype of Behçet's disease, symptom and laboratory data at onset, colonoscopic findings, such as distribution of lesions as well as number, size, depth, and shape of ulcer, and initial treatment (medical vs. surgical) did not affect relapse rate. However, large ulcers (> 20 mm) and young age at onset (< 37 years old) were factors significantly related with higher relapse rate (P < 0.05, log,rank test). Conclusion, High relapse rate in intestinal Behçet's disease was identified. Age at onset and size of the ulcer are factors related with long-term prognosis of intestinal Behçet's disease. [source]

    Histometric and Histochemical Analysis of the Effect of Trichloroacetic Acid Concentration in the Chemical Reconstruction of Skin Scars Method

    DERMATOLOGIC SURGERY, Issue 10 2006
    SUNG BIN CHO MD
    BACKGROUND Atrophic scars can be induced by various causes, including severely inflamed acne, chicken pox, and trauma. Many treatment modalities are used for reconstructing and improving the appearance of scars with various treatment results. OBJECTIVE A recent report shows the clinical efficacy of the chemical reconstruction of skin scars (CROSS) method, which consists of the focal application of trichloroacetic acid (TCA) in a higher concentration. Histometric analysis of the CROSS method, however, has not yet been established. METHODS In this study, five hairless mice were used to evaluate the effect of the CROSS method and to analyze the difference between the CROSS method and simple TCA application. RESULTS Similar histologic changes were observed in the two methods, including epidermal and dermal rejuvenation with new collagen deposition. These changes, however, were more prominent in the CROSS method,treated areas, particularly when 100% TCA was used. CONCLUSION The results of this study suggest that treatment of atrophic scars using the CROSS method is more effective than simple application of TCA in activating fibroblasts in the dermis and increasing the amount of collagen.

    Study of the MR relaxation of microglia cells labeled with Gd-DTPA-bearing nanoparticles

    CONTRAST MEDIA & MOLECULAR IMAGING, Issue 3 2009
    Emeline Julie Ribot
    Abstract Therapies involving cells as vehicles need to visualize in situ the trafficking of the cells concerned. This cellular imaging can be driven by cell contrast agent-based nanoparticle internalization and non-invasive MRI (magnetic resonance imaging) detection. Here, microglial cells, that would transport a suicide gene to a glioma, were incubated for different times, with various concentrations of silica nanoparticles on which numerous Gd-DTPA were grafted. The goal of this study was to investigate the repartition of cell-associated particles. MRI was used to quantitatively follow the particle uptake process. Fluorescence microscopy images showed that, although most of the nanoparticles were internalized, some remained adsorbed on the extracellular membrane surface. The cells were then submitted to various treatments: glycine to release bound nanoparticles and/or ultrasound to destroy the cell membranes. The R1 relaxation rates were measured at 4.7 T. R1 was maximal for 4,h of incubation, decreased after 8,h and remained stable for the 24 following hours. The magnetic resonance signal of ultrasonicated and glycine-treated cells made it possible to quantify the loss of bound nanoparticles after 8,h. Nevertheless, this release did not prevent cell detection since the internalized nanoparticles are enough concentrated to visualize the labeled cells even after 4 days of cell growth. These results highlight the compartmentalization of nanoparticles in microglia and the evolution of the MR signal of the labeled cells. This study could be of importance to interpret in vivo the MR signal changes that could occur after administration of such nanoparticle-labeled cells in therapeutic strategies.

    Intense Pulsed Light for the Treatment of Refractory Melasma in Asian Persons

    DERMATOLOGIC SURGERY, Issue 9 2004
    Chia-Chen Wang MD
    Background. Patients with dermal or mixed-type melasmas are often refractory to various treatments. Intense pulsed light has been used to treat melanocytic lesions with promising results. Objective. The purpose of this study was to clarify the effectiveness of intense pulsed light for refractory melasma in Asian persons. Methods. Seventeen patients were treated with intense pulsed light, during four sessions at 4-week intervals. The patients were also given 4% hydroquinone cream and broad-spectrum sunscreens to prevent and treat postinflammatory hyperpigmentation. Sixteen patients in the control group were treated with hydroquinone cream and sunscreens. The treatment efficacy was evaluated using reflectance spectrophotometer and patient satisfaction questionnaire. Results. Patients in the intense pulsed light group achieved an average of 39.8% improvement in relative melanin index, compared to 11.6% improvement in the control group (p<0.05) at Week 16. Six (35%) patients in the intense pulsed light group had more than 50% improvement, compared to two (14%) patients in the control group. Two patients in the intense pulsed light group, however, experienced transient postinflammatory hyperpigmentation, and partial repigmentation was noted 24 weeks after the last treatment session. Conclusion. Intense pulsed light is a safe and effective treatment for refractory melasma in Asian persons, with minimal side effects. Further treatment sessions are required for maintenance therapy.

    Experiments on the susceptibility of conifers to Heterobasidion annosum in Great Britain

    FOREST PATHOLOGY, Issue 4 2001
    Greig
    During the period 1960,71, experimental plantings were established at three sites in western Britain that were infested with Heterobasidion annosum: Ceri in mid-Wales, Lael in north-west Scotland and Red Marley in the West Midlands of England. At each site a randomized block experiment involving at least four species was supplemented with an ancillary trial of other species. In two of the experiments various treatments were applied to the previous stand of trees before or at felling, but only stump removal reduced the amount of disease in the succeeding crops. At Ceri, the incidence of H. annosum in stems removed at first thinning was: Picea sitchensis, 14%; Pseudotsuga menziesii 11%; Pinus contorta 3% and Abies procera 1%. At Lael, the figures were Larix decidua 59%; P. menziesii 51%; Chamaecyparis lawsoniana 37%; Abies amabilis 33% and Tsuga heterophylla 21%. There was negligible disease in A. procera;Abies grandis and Pinus sylvestris. At Red Marley, the incidence of disease was: P. menziesii 28%; T. heterophylla 18%; A. grandis 7%; Picea abies 1% and Pinus nigra var. maritima 0%. In the ancillary trial at Lael, the incidence of H. annosum in P. sitchensis was 55% and in P. abies 16%. The mean height of colonization by H. annosum within the diseased stems removed at first thinning at Lael (age 21,22 years) was 2.1 m for L. decidua, 1.4 m for P. sitchensis and 1.3 m for P. abies. Armillaria sp. caused mortality and decay in two of the experiments and these data are also presented. The results are discussed in relation to other information on the susceptibility of these species to H. annosum in the UK and elsewhere. Expérimentations sur la sensibilité des conifères à Heterobasidion annosum Entre 1960 et 1971, des plantations expérimentales ont été installées dans trois sites infectés par Heterobasidion annosum dans l'ouest de la Grande-Bretagne: à Ceri (centre du Pays de Galles), à Lael (nord-ouest de l'Écosse), et à Red Marley (ouest des Midlands, Angleterre). Dans chaque site, un essai en blocs randomisés comprenant au moins quatre espèces a été complété avec des espèces supplémentaires. Dans deux des essais, divers traitements ont été appliqués au peuplement antérieur ou au moment de son exploitation, mais seul l'arrachage des souches avait réduit la quantité de maladie. A Ceri, l'incidence de H. annosum dans les tiges enlevées à la première éclaircie était la suivante: Picea sitchensis, 14%; Pseudotsuga menziesii, 11%; Pinus contorta, 3% et Abies procera, 1%. A Lael: Larix decidua, 59%; Pseudotsuga menziesii, 51%; Chamaecyparis lawsoniana, 37%; Abies amabilis, 33%; Tsuga heterophylla, 21%. La maladie était négligeable chez A. procera, A. grandis et Pinus sylvestris. A Red Marley, l'incidence était la suivante: Pseudotsuga menziesii, 28%; Tsuga heterophylla, 18%; Abies grandis, 7%; Picea abies, 1% et Pinus nigra var. maritima, 0%. Chez les espèces supplémentaires à Lael, l'incidence était de 55% chez Picea sitchensis et de 16% chez P. abies. La hauteur moyenne de colonisation des tiges infectées par H. annosum, prélevées à la première éclaircie à Lael (age: 21,22 ans) était de 2,1 m chez Larix decidua, 1,4 m chez Picea sitchensis et 1,3 m chez P. abies. Armillaria sp. provoquait des mortalités et des altérations dans deux des essais et ces données sont également présentées. Les résultats sont discutés en relation avec d'autres informations sur la sensibilité de ces espèces àH. annosum au Royaume-Uni et ailleurs. Versuche zur Anfälligkeit von Nadelgehölzen gegen Heterobasidion annosum in Grossbritannien Während der Jahre 1960,71 wurden an drei Standorten im Westen Großbritanniens Versuchspflanzungen angelegt, die von Heterobasidion annosum befallen waren (Ceri in Mittelwales, Lael in Nordwest-Schottland und Red Marley im westlichen Mittelland von England). An jedem Standort wurde ein randomisierter Blockversuch mit mindestens vier Baumarten angelegt. Ergänzend wurden zusätzliche Arten getestet. Auf zwei Versuchsflächen wurden unterschiedliche Behandlungen des Vorbestandes bzw. der Fläche durchgeführt. Das Auftreten der Krankheit im Folgebestand konnte nur durch die Rodung der Stümpfe reduziert werden. In Ceri wurden bei den in der ersten Durchforstung entnommenen Stämmen folgende Infektionshäufigkeiten festgestellt: Picea sitchensis 14%, Pseudotsuga menziesii 11%, Pinus contorta 3% und Abies procera 1%. In Lael ergab sich folgendes Bild: Larix decidua 59%, Pseudotsuga menziesii 51%, Chamaecyparis lawsoniana 37%, Abies amabilis 33% und Tsuga heterophylla 21%. Der Befall von Abies grandis, A. procera and Pinus sylvestris war vernachlässigbar gering. In Red Marley betrug die Infektionshäufigkeit bei Pseudotsuga menziesii 28%, bei Tsuga heterophylla 18%, Abies grandis 7%, Picea abies 1% und Pinus nigra var. maritima 0%. In dem Ergänzungsversuch in Lael waren Picea sitchensis zu 55% und P. abies zu 16% von H. annosum infiziert. Die mittlere Höhe der Ausbreitung von H. annosum in den erkrankten Stämmen, die bei der ersten Durchforstung entfernt wurden, betrug in Lael (Alter 21,22 Jahre) 2,1 m bei Larix decidua, 1,4 m bei Picea sitchensis und 1,3 m bei P. abies. Auch Armillaria sp. verursachte Mortalität und Fäule. Diese Daten werden ebenfalls präsentiert. Die Ergebnisse werden im Vergleich mit der verfügbaren Information zur Anfälligkeit dieser Baumarten diskutiert. [source]

    The microbiological and chemical composition of silage over the course of fermentation in round bales relative to that of silage made from unchopped and precision-chopped herbage in laboratory silos

    GRASS & FORAGE SCIENCE, Issue 3 2008
    J. McEniry
    Abstract The composition of baled silage frequently differs from that of comparable conventional silage. A factorial experiment was conducted with three wilting treatments (0, 24 or 48 h) × three ensiling systems [unchopped grass in bales, unchopped grass in laboratory silos (LS), precision-chopped grass in LS] × six stages of ensiling to (i) confirm that the fermentation of unchopped grass in LS could be used as an adequate model for baled silage fermentation, (ii) quantify the differences between baled silage and silage made from precision-chopped herbage across a range of dry-matter contents and (c) quantify the fermentation dynamics within the various treatments. The onset of fermentation as evidenced by the accumulation of fermentation products and the decline in pH were slower (P < 0·05) in baled silage compared with silage made from precision-chopped herbage. Furthermore the pH (P < 0·001) and overall concentration of fermentation acids (P < 0·01) were lower while ammonia-N concentration was generally higher in baled silage, making it more conducive to the activities of Clostridia, Enterobacteria and yeast. Numbers of Enterobacteria were higher (P < 0·001) in baled silage in the early stages of ensilage and persisted in baled silage at the end of the storage period. The implications of a slower onset of fermentation in baled herbage are greater in farm practice, as the fermentation would be further restricted by a more extensive wilting of the herbage prior to ensiling.

    Lack of desquamation , the Achilles heel of the reconstructed epidermis

    INTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Issue 5 2002
    M. Ponec
    Synopsis The use of human skin equivalents for screening tests aiming to assess repetitive application of various test agents is hampered by the lack of desquamation in vitro. The present study was undertaken to examine whether the desquamation can be induced by various treatments including mechanical stress, application of various agents that should decrease the surface pH and calcium level, activate the enzymes involved in desquamation process or UV irradiation. In addition, the effect of ,-hydroxyacids, known to enhance desquamation and to improve the stratum corneum barrier function in vivo, was examined as well. Human epidermis reconstructed on de-epidermized dermis or on fibroblast-populated collagen matrices during a 2-week culture at the air,liquid interface underwent various treatments during an additional 3-week period. The effects of treatments were evaluated on the basis of tissue morphology and lipid composition. The results of the present study revealed that cell shedding could only be induced by a mild repetitive mechanical treatment. The lack of desquamation, under most in vitro conditions, has a practical consequence, since it may hamper the use of reconstructed epidermis for various screening studies aiming to examine the repetitive exposure to topical agents or UV irradiation. The gradual thickening of the stratum corneum will lead to its higher resistance to the environmental stimuli and in this way affect the outcome of the tests. Furthermore, from the results obtained in the present study, it became evident that one should be careful in selecting endpoints when, for example, the effects of agents known to modulate melanogenesis are examined. Résumé L'utilization d'équivalents cutanés humains dans les procédures de criblage, afin d'estimer l'action répétée de divers agents, est entravée par l'absence de desquamation in vitro. La présente étude a été entreprise afin de déterminer dans quelle mesure la desquamation peut être induite par différents traitements tels que stress mécanique, application d'agents divers qui conduiraient à une chute du pH de surface et du taux de Calcium, activeraient les enzymes impliquées dans le processus de desquamation, ou l'irradiation UV. De plus, l'effet des , hydroxy-acides, connus pour favouriser la desquamation et d'améliorer la fonction barrière du Stratum-Corneum in vivo, a étéétudié. L'épiderme humain reconstruit sur un derme dé-épidermisé ou sur des matrices de collagène colonisées par des fibroblastes pendant 2 semaines de culture, en interface air × liquide, a subi divers traitements pendant une période additionnelle de 3 semaines. Les effets de ces traitements étaient évalués sur des critères morphologiques du tissu ainsi que la composition en lipides. Les résultats de cette étude montrent que l'élimination cellulaire ne peut être induite que par un léger traitement mécanique répété. L'absence de desquamation dans la plupart des conditions in vitro a une conséquence pratique puisqu'elle peut entraver l'utilization de l'épiderme reconstruit à des fins diverses de criblage en vue d'appréhender les expositions répétées à des agents topiques, ou l'irradiation UV. L'épaississement progressif du Stratum-Corneum lui confèrera une résistance accrue aux stimuli environnementaux qui, en retour, modifiera les résultats des tests. De plus, les résultats de cette présente étude impliquent à l'évidence une précaution dans la sélection des cinétiques de mesures lorsque, par exemple, les effets des agents connus pour moduler la mélanogénèse sont étudiés.

    Meta-analysis of the effectiveness of psychological and pharmacological treatments for binge eating disorder

    INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 3 2010
    Silja Vocks PhD
    Abstract Objective: The aim of this study was to compute and compare mean effects of various treatments for binge eating disorder. Method: A total of 38 studies with 1973 participants fulfilled the defined inclusion criteria. Effect sizes, odds ratios, and simple rates were integrated in fixed and random (mixed) effects categorical models. Results: From randomized controlled trials, psychotherapy and structured self-help, both based on cognitive behavioral interventions, were found to have large effects on the reduction of binge eating. Regarding pharmacotherapy, mainly comprising antidepressants, randomized controlled trials revealed medium effects for the reduction of binge eating. Uncontrolled studies on weight-loss treatments demonstrated moderate reductions of binge eating. Combination treatments did not result in higher effects compared with single-treatment regimens. Except for weight-loss treatment, none of the interventions resulted in a considerable weight reduction. Discussion: Psychotherapy and structured self-help, both based on cognitive-behavioral interventions, should be recommended as the first-line treatments. © 2009 by Wiley Periodicals, Inc.

    In vitro haem solubility of red cell fraction of porcine blood under various treatments

    INTERNATIONAL JOURNAL OF FOOD SCIENCE & TECHNOLOGY, Issue 4 2010
    Tong-Xun Liu
    Summary An in vitro peptic digestion at gastric pH 2.0 was used to assess the haem solubility of red cell fraction (RCF) of porcine blood derived samples. The in vitro haem solubility of the RCF decreased greatly in the denaturated form of haemoglobin. However, the native haemoglobin was susceptible to be hydrolysed by enzyme mixture of Flavourzyme and Alcalase. The in vitro digestion of the hydrolysates showed that the highest haem solubility was reached at degree of hydrolysis between 8.75% and 12.33%. The in vitro haem solubility was positively correlated with content of the highly soluble peptides with molecular weights ranged from 7.5 kDa to 1 kDa, but negatively with peptides fractions >7.5 kDa and <1 kDa, mostly due to the precipitation of the highly molecular weight fraction (>7.5 kDa) and part of small peptides (<1 kDa) with higher haem/peptide ratio, which was confirmed by gel filtration chromatograms and by the analysis of the precipitate at pH 2.0.

    Preparation of tofu using chitosan as a coagulant for improved shelf-life

    INTERNATIONAL JOURNAL OF FOOD SCIENCE & TECHNOLOGY, Issue 2 2004
    Hong Kyoon No
    Summary The potential of chitosan as a coagulant in commercial tofu preparation was investigated with six chitosans of different molecular weights using various treatments. The following optimum processing conditions for tofu preparation were proposed: chitosan with a molecular weight of 28 kDa; chitosan solution type, 1% chitosan/1% acetic acid; chitosan solution to soymilk ratio, 1 : 8; coagulation temperature, 80 °C; coagulation time, 15 min. However, the sensory quality of tofu was notably improved using a 1 : 1 mixture of 1% acetic acid and 1% lactic acid instead of 1% acetic acid alone as a chitosan solvent. Tofu prepared with chitosan had lower ash and higher protein content than those of commercial products tested. In storage tests, the chitosan-tofu had a longer shelf-life, about 3 days, than tofu made with CaCl2. This added shelf-life is significant in view of the magnitude (366 000 tonnes year,1) of tofu produced from commercial tofu plants (1407 plants as of 1998) in Korea. [source]

    Etude comparative de la disponibilité de l'eau en irrigation goutte à goutte

    IRRIGATION AND DRAINAGE, Issue 3 2001
    A.V. Ould Mohamed El-Hafedh
    goutteur; écartement; durée d'irrigation; fréquence d'arrosage Abstract Dans le but de déterminer la meilleure combinaison entre période et durée d'irrigation pour différents écartements inter-goutteurs, nous avons essayé d'analyser la disponibilité de l'eau au sein de la zone racinaire d'une culture de tomate irriguée à l'aide d'une rampe de goutteurs débitant chacun 4 l h,1. Trois écartements ont été étudiés à savoir 30, 50 et 70 cm. Lorsqu'on a pris une durée d'arrosage systématique de 4h30mn, nous avons observé à la fin des irrigations des teneurs en eau volumiques moyennes dépassant la capacité au champ pour les trois écartements. En effet, à l'examen de l'évolution des teneurs en eau au sein du bulbe, il est remarqué que la teneur en eau à la capacité au champ a été atteinte après 25 minutes, 50 minutes et deux heures respectivement pour 30, 50 et 70 cm. Mais l'humidification de toute la ligne de culture n'a été observée qu'après des temps respectifs d'une heure, deux heures et quatre heures (Ould Mohamed El-Hafedh et al., 2000). Les irrigations ont été reprises avec ces durées réduites (une heure, deux heures et quatre heures respectivement pour les écartements 30, 50 et 70 cm) en vue d'évaluer et comparer les consommations en eau de la culture sous les différents traitements. Dans le cas de l'irrigation d'une durée de 4h30mn, la période séparant deux arrosages successifs a été de cinq, quatre et trois jours respectivement pour les écartements 30, 50 et 70 cm. Pour les irrigations des durées réduites, on a constaté qu'il est impératif d'irriguer après trois jours pour les deux écartements 50 et 70 cm et après deux jours pour l'écartement 30 cm. En comparant les consommations en eau pour les durées réduites et la durée systématique de 4h30mn, on a observé une économie d'eau de l'ordre de 20, 15 et 5% respectivement pour 30, 50 et 70 cm d'écartement. D'autre part, la comparaison entre les durées réduites montre que la plus importante économie en eau a été réalisée avec 50 cm d'écartement. Copyright © 2001 John Wiley & Sons, Ltd. In order to determine the best combination between duration and frequency of drip irrigation for various inter-dripper spacing, we analysed the availability of water within the root zone of a tomato culture irrigated using lateral drippers each outputting 4 l h,1 discharge rate. Three spacings were studied, namely 30, 50 and 70 cm. Studying systematic irrigation duration of 4½ hours, we observed at the end of each irrigation average volumetric water contents exceeding the field capacity. Indeed, with the examination of the evolution of the water contents within the bulb, it is noticed that the water content at the field capacity was reached after 25 minutes, 50 minutes and 2 hours respectively for 30, 50 and 70 cm spacing. But the humidification of the whole culture line was observed only after the respective times of 1, 2 and 4 hours (Ould Mohamed El-Hafedh et al., 2000). The irrigations were taken again with these reduced durations (1, 2 and 4 hours for 30, 50 and 70 cm spacing respectively) in order to evaluate and compare water consumption of the culture under the various treatments. In case of systematic irrigation duration, the period separating two successive waterings was five, four and three days for 30, 50 and 70 cm spacing respectively. For the reduced irrigation durations, it is imperative to irrigate after three days for the 50 and 70 cm spacings and after two days for the 30 cm spacing. Comparing water consumption for the reduced durations and those of the systematic duration, we observed water savings of about 20, 15 and 5% respectively for 30, 50 and 70-cm spacing. The comparison between the reduced durations shows that the most significant water saving was obtained with the 50 cm spacing. Copyright © 2001 John Wiley & Sons, Ltd. [source]

    Evidence-based (S3) guidelines for the treatment of psoriasis vulgaris

    JOURNAL DER DEUTSCHEN DERMATOLOGISCHEN GESELLSCHAFT, Issue 2007
    Alexander Nast
    Abstract Psoriasis vulgaris is a common and often chronic inflammatory skin disease. The incidence of psoriasis in Western industrialized countries ranges from 1 to 2%. Patients afflicted with severe psoriasis vulgaris may experience a significant reduction in quality of life. Despite the large variety of treatment options available, patient surveys have revealed lack of satisfaction with the efficacy of available treatments and a high rate of non-compliance. To optimize the treatment of psoriasis in Germany, the Deutsche Dermatologische Gesellschaft (DDG) and the Berufsverband Deutscher Dermatologen (BVDD) initiated a project to develop evidence-based guidelines for the management of psoriasis. These resulting Guidelines focus on induction therapy in cases of mild, moderate, and severe plaquetype psoriasis in adults. The Guidelines include evidence-based evaluation of the efficacy of all currently available therapeutic options in Germany. In addition, they offer detailed information on how best to administer the various treatments and give information on contraindications, adverse drug reactions, and drug interactions as well as estimates of practicability and cost. The Guidelines were developed following the recommendations of the Arbeitsgemeinschaft wissenschaftlicher medizinischer Fachgesellschaften (AWMF). The therapeutic recommendations were developed by an expert group and finalized during interdisciplinary consensus conferences. [source]

    Differential sensitivity to apoptosis between the human small and large intestinal mucosae: Linkage with segment-specific regulation of Bcl-2 homologs and involvement of signaling pathways,

    JOURNAL OF CELLULAR BIOCHEMISTRY, Issue 2 2001
    Rémy Gauthier
    Abstract The small and large intestines differ in their expression profiles of Bcl-2 homologs. Intestinal segment-specific Bcl-2 homolog expression profiles are acquired as early as by mid-gestation (18,20 weeks) in man. In the present study, we examined the question whether such distinctions underlie segment-specific control mechanisms of intestinal cell survival. Using mid-gestation human jejunum and colon organotypic cultures, we analyzed the impact of growth factors (namely insulin; 10 ,g/ml) and pharmacological compounds that inhibit signal transduction molecules/pathways (namely tyrosine kinases, Fak, PI3-K/Akt, and MEK/Erk) on cell survival and Bcl-2 homolog expression (anti-apoptotic: Bcl-2, Bcl-XL, Mcl-1; pro-apoptotic: Bax, Bak, Bad). The relative activation levels of p125Fak, p42Erk-2, and p57Akt were analyzed as well. Herein, we report that (1) the inhibition of signal transduction molecules/pathways revealed striking differences in their impact on cell survival in the jejunum and colon (e.g., the inhibition of p125Fak induced apoptosis with a significantly greater extent in the jejunum [,43%] than in the colon [,24%]); (2) sharp distinctions between the two segments were noted in the modulatory effects of the various treatments on Bcl-2 homolog steady-state levels (e.g., inhibition of tyrosine kinase activities in the jejunum down-regulated all anti-apoptotics analyzed while increasing Bax, whereas the same treatment in the colon down-regulated Bcl-XL only and increased all pro-apoptotics); and (3) in addition to their differential impact on cell survival and Bcl-2 homolog expression, the MEK/Erk and PI3-K/Akt pathways were found to be distinctively regulated in the jejunum and colon mucosae (e.g., insulin in the jejunum increased p42Erk-2 activation without affecting that of p57Akt, whereas the sa e treatment in the colon decreased p42Erk-2 activation while increasing that of p57Akt). Altogether, these data show that intestinal cell survival is characterized by segment-specific susceptibilities to apoptosis, which are in turn linked with segmental distinctions in the involvement of signaling pathways and the regulation of Bcl-2 homolog steady-state levels. Therefore, these indicate that cell survival is subject to segment-specific control mechanisms along the proximal-distal axis of the intestine. J. Cell.

    Enhancement of activity and selectivity in lipase-catalyzed transesterification in ionic liquids by the use of additives

    JOURNAL OF CHEMICAL TECHNOLOGY & BIOTECHNOLOGY, Issue 10 2007
    Francisco J Hernández-Fernández
    Abstract BACKGROUND: Seven ionic liquids (ILs) based on 1-alkyl-3-methylimidazolium cation in combination with hexafluorophosphate and bis{(trifluoromethyl)sulfonyl}imide anions were tested as reaction media for lipase-catalyzed transesterification in low water conditions. With the aim of improving the activity and/or selectivity of the lipase, various treatments were applied to ionic liquid media such as equilibration with aqueous solutions of salts, NaHCO3 or Na2CO3, or the addition of a catalytic amount of a non-reactive organic base to the reaction mixture, triethylamine. RESULTS: The treated ionic liquids were shown to be excellent media for lipase-catalyzed ester synthesis by transesterification compared with conventional organic solvents, such as n -hexane. All treatments were found to enhance the synthetic activity of the enzyme, the best results being achieved with the addition of triethylamine. The addition of a catalytic amount of this base to the ILs resulted in a significant increase in both the synthetic activity and selectivity values. For instance, the synthetic activity in [emim+][TfN2,] was enhanced more than 12 times and the selectivity increased from 86% to 95% when triethylamine was used. CONCLUSION: These treatments could be easy-to-use approaches to improve the efficiency of enzymatic reactions in ionic liquids when the reaction does not proceed smoothly.

    Comparative analysis of CFD models of dense gas,solid systems

    AICHE JOURNAL, Issue 5 2001
    B. G. M. van Wachem
    Many gas,solid CFD models have been put forth by academic researchers, government laboratories, and commercial vendors. These models often differ in terms of both the form of the governing equations and the closure relations, resulting in much confusion in the literature. These various forms in the literature and in commercial codes are reviewed and the resulting hydrodynamics through CFD simulations of fluidized beds compared. Experimental data on fluidized beds of Hilligardt and Werther (1986), Kehoe and Davidson (1971), Darton et al.(1977), and Kuipers (1990) are used to quantitatively assess the various treatments. Predictions based on the commonly used governing equations of Ishii (1975) do not differ from those of Anderson and Jackson (1967) in terms of macroscopic flow behavior, but differ on a local scale. Flow predictions are not sensitive to the use of different solid stress models or radial distribution functions, as different approaches are very similar in dense flow regimes. The application of a different drag model, however, significantly impacts the flow of the solids phase. A simplified algebraic granular energy-balance equation is proposed for determining the granular temperature, instead of solving the full granular energy balance. This simplification does not lead to significantly different results, but it does reduce the computational effort of the simulations by about 20%. [source]

    The impact of cold temperatures during grain maturation on selected quality parameters of wheat

    JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE, Issue 9 2007
    Maryke Craven
    Abstract The influence of sudden cold spells during grain filling of wheat on the quality traits of three South African hard red wheat cultivars (Gariep, Elands and Tugela-DN) was studied, with the emphasis on Hagberg falling number (HFN). Four treatments were used (,1 °C at soft dough stage, , 1 °C at late milk stage, , 4 °C at soft dough stage and , 4 °C at late milk stage) and were administered for one night only. From the results it was concluded that, although limited in duration, such frost conditions did have an effect on the quality of the wheat cultivars. Cultivars differed in their response to the various treatments but also as to what quality traits were affected the most. The , 4 °C at late milk stage resulted in significantly reduced HFN being measured for both Elands and Tugela-DN. A similar effect was observed for Gariep, but was not statistically significant. Although the response was limited to the main tillers only, the conclusion was made that it is probable that the reduced HFN would be visible in the pooled sample of head and side tillers. A screening protocol was suggested that would allow classification of cultivars for frost tolerance. Copyright © 2007 Society of Chemical Industry [source]

    The Influence of Artemia and Algal Supplements during the Nursery Phase of Rearing Pacific White Shrimp, Litopenaeus vannamei

    JOURNAL OF THE WORLD AQUACULTURE SOCIETY, Issue 4 2007
    Oscar Zelaya
    A 21-d nursery trial was conducted to evaluate various food supplements on growth and survival of postlarval (PL) Litopenaeus vannamei. Each of four treatments was provided with an equal quantity of a dried commercial feed throughout the study. Three treatments received algae paste (Thalassiosira weissflogii) supplemented every 3 d. These include F, commercial feed plus algae; FAr3, commercial feed plus algae plus Artemia every other day during the first 7 d; and FAr7, commercial feed plus algae plus Artemia every day during the first 7 d. The fourth treatment served as control (FNA); it relied only on the commercial feed plus naturally occurring algae. At the conclusion of the nursery period, there were no significant differences in survival or feed conversion ration for PL nursed in the various treatments. Artemia did have some effect in that PL receiving Artemia supplement for 3 d (FAr3) were significantly larger than those that did not. Algal paste in itself had no significant effect. Overall, results suggest an advantage to supplementing dried feed with Artemia for at least 3 d during the first week of nursery culture but little advantage to the use of a diatom paste as a food supplement.

    Helophyte germination in a Mediterranean salt marsh: Gut-passage by ducks changes seed response to salinity

    JOURNAL OF VEGETATION SCIENCE, Issue 3 2004
    J.L. Espinar
    Abstract: Question: In seeds which are regularly consumed by waterbirds in the field, how does gut-passage modify their response to salinity gradients? Location: Doñana National Park salt marsh, south-west of Spain. Methods: Seeds of Scirpus litoralis and Scirpus maritimus were collected and force fed to mallards (Anas platyrhynchos). Both the ingested seeds (passage) and non-ingested seeds (controls) were exposed, in germination chambers, to a salinity range similar to that observed in the field (0,32 dS/m). After 30 days, the total percentage germination, the duration of the dormancy period and the germination speed were computed. The response of the different germination parameters to ingestion and salinity was analyzed using generalized lineal models. Recovery tests on seeds that did not germinate in the various treatments and tests of the effect of ingestion on the intrinsic variability in seed response were also performed. Results: An increase in salinity reduced germinability and increased the length of dormancy, while gut pas sage increased the intrinsic variability of the temporal seed response in both species. In S. litoralis there was a significant interaction between the effects of salinity and passage on germination rate. Passage increased germination rate at low salinities (,2 dS/m) but decreased it at high salinities (,4 dS/m). Conclusion: Gut-passage by ducks significantly changes seed response to salinity. The outcome of plant-animal interactions can be influenced by environmental gradients. Studies of germination in response to gut passage that do not take such gradients into account may produce misleading results. [source]

    LASERS IN SURGERY AND MEDICINE, Issue 4 2002
    Toru Eguro DDS
    Abstract Background and Objectives The investigation of adhesion between an Er:YAG laser-irradiated surface and composite resin is very important to ensure the best clinical results. The purpose of this investigation is to determine if the application of various treatments on Er:YAG laser-irradiated dentin surface affects the tensile bond strength between dentin and composite resins. Study Design/Materials and Methods In this investigation, the application of phosphoric acid, ultrasonic scaler, air-scaler, and air-powder polisher were tested as techniques to increase the bond strength of composite resins to Er:YAG laser-irradiated dentin surface. Results The tensile bond strength of the air-powder polished group was highest, at 18.45,±,3.72 MPa, and the lowest value was that of the only laser-irradiated group, at 12.56,±,4.38 MPa. Conclusions The bond strengths in treated with air-powder polished group and phosphric acid etched group were significantly higher than that of the group in laser irradiation alone. Lasers Surg.

    Citric acid production by Aspergillus niger ATCC 9142 from a treated ethanol fermentation co-product using solid-state fermentation

    LETTERS IN APPLIED MICROBIOLOGY, Issue 5 2009
    G. Xie
    Abstract Aims:, To investigate the ability of the citric acid-producing strain Aspergillus niger ATCC 9142 to utilize the ethanol fermentation co-product corn distillers dried grains with solubles for citric acid production following various treatments. Methods and Results:, The ability of A. niger ATCC 9142 to produce citric acid and biomass on the grains was examined using an enzyme assay and a gravimetric method, respectively. Fungal citric acid production after 240 h was higher on untreated grains than on autoclaved grains or acid-hydrolysed grains. Fungal biomass production was enhanced after autoclaving and acid-hydrolysis of the grains. Phosphate supplementation to the grains slightly stimulated citric acid production while methanol addition decreased its synthesis. Using the phosphate-supplemented grains, the optimal incubation temperature, initial moisture content of the grains and the length of fermentation time for ATCC 9142 citric acid production were determined to be 25°C, 82% and 240 h, respectively. Conclusions:,A. niger ATCC 9142 synthesized citric acid on corn distillers dried grains with solubles. The phosphate-treated grains increased citric acid production by the strain. Significance and Impact of the Study:, The ethanol fermentation co-product corn distillers dried grains with solubles could be useful commercially as a substrate for A. niger citric acid production.

    Rheumatoid arthritis patients' knowledge of the disease and its treatments: A descriptive study

    MUSCULOSKELETAL CARE, Issue 1 2009
    P. Mäkeläinen MNSc
    Abstract Objective:,The purpose of rheumatoid arthritis (RA) patient education is to increase patients' knowledge levels. However, there are only a limited number of studies available concerning these patients' knowledge of their disease and its various treatments. The purpose of this study was to describe RA patients' understanding of their disease and its treatments. Methods:,A total of 252 RA patients participated in this survey in August 2004 (response rate 53.2%). The knowledge levels of the patients and their physical functioning were measured using self-reported questionnaires. The data were analysed using descriptive and non-parametric statistical methods. Results:,RA patients' knowledge of the disease and its treatments was, on average, good. However, the total scores of the Patient Knowledge Questionnaire ranged from 2 to 29 (maximum score 30). The patients knew well the aetiology and symptoms of RA, the blood tests and the physical exercise; they knew moderately well the facts relating to joint protection, energy conservation and how to use anti-rheumatic drugs and non-steroidal anti-inflammatory drugs. Young patients, women and patients with a long disease duration knew the most. There was a weak correlation between patient knowledge and physical functioning: the weaker the patient's functioning, the higher the knowledge level. Conclusions:,RA patients' knowledge of their disease and its treatments varied from poor to good in this group. These results can be used for advancing RA patient education. However, more research is needed to evaluate RA patients' knowledge levels. Copyright © 2008 John Wiley & Sons, Ltd. [source]

    An Updated Interdisciplinary Clinical Pathway for CRPS: Report of an Expert Panel

    PAIN PRACTICE, Issue 1 2002
    Dr. med, Michael D. Stanton-Hicks MB
    Abstract: The goal of treatment in patients with complex regional pain syndrome (CRPS) is to improve function, relieve pain, and achieve remission. Current guidelines recommend interdisciplinary management, emphasizing 3 core treatment elements: pain management, rehabilitation, and psychological therapy. Although the best therapeutic regimen or the ideal progression through these modalities has not yet been established, increasing evidence suggests that some cases are refractory to conservative measures and require flexible application of the various treatments as well as earlier consideration of interventions such as spinal cord stimulation (SCS). While existing treatment guidelines have attempted to address the comprehensive management of CRPS, all fail to provide guidance for contingent management in response to a sudden change in the patient's medical status. This paper reviews the current pathophysiology as it is known, reviews the purported treatments, and provides a modified clinical pathway (guideline) that attempts to expand the scope of previous guidelines.

    Effects of low temperature buffer layer treatments on the growth of high quality ZnO films

    PHYSICA STATUS SOLIDI (C) - CURRENT TOPICS IN SOLID STATE PHYSICS, Issue 4 2004
    H. Tampo
    Abstract ZnO films were grown on sapphire substrates by radical source molecular beam epitaxy (RS-MBE). ZnO low temperature buffer layers were subjected to various treatments. High quality ZnO films were obtained by vacuum annealing plus nitrogen doping of the buffer layer. The carrier concentration of the ZnO film fabricated using this buffer layer was 7.5 × 1016 cm,3 with a mobility of 132 cm2/V sec at RT. Temperature dependent Hall measurements showed implied the existence of degenerate (untreated) buffer layers. Using a nitrogen-doped buffer layer to reduce the influence of the degenerate layer, a donor energy of 110 meV was estimated from temperature dependent Hall measurements.

    Latest news and product developments

    PRESCRIBER, Issue 3 2007
    Article first published online: 14 MAR 200
    PPIs and hip fracture Treatment with a PPI may increase the risk of hip fracture, with longer use associated with higher risk according to a study in UK patients (J Am Med Assoc 2006;297:2947-53). The case control study compared use of PPIs by 13 556 patients with hip fracture and 135 386 controls in the UK General Practice Research Database. Use of a PPI for more than one year was associated with an increase of 44 per cent in the odds of hip fracture. The risk was higher for longer- term use (59 per cent after four years) and at higher doses (more than doubled with long-term high doses). The mechanism for this possible effect may be impaired calcium absorption associated with hypochlorhydria and reduced bone resorption. CHD NSF Statin prescribing has increased by 30 per cent every year since the publication of the Coronary Heart Disease NSF, the Department of Health says. The estimated number of lives saved attributable to statins had risen to 9700 in 2005. The proportion of patients with acute MI who were given thrombolysis within 30 minutes of admission has increased to 83 per cent. Flu jabs cut pneumonia deaths A US study suggests that flu vaccine protects against death during the flu season in patients admitted with community-acquired pneumonia (Arch Intern Med 2007;167:53-9). Nineteen per cent of patients admitted with pneumonia during the winters of 1999-2003 were known to have been vaccinated against flu. Their risk of death during their hospital stay was 70 per cent lower than that of nonvaccinated individuals. After adjustment for antipneumococcal vaccination and comorbidity, the odds of death were still 39 per cent lower. Model to predict admissions The King's Fund, together with New York University and Health Dialog, has published a model that predicts the risk of emergency hospital admission (see www.kingsfund.org.uk). The model is intended for use by PCTs and draws on data from secondary and primary care to define clinical profiles, allowing patients whose condition is deteriorating to be identified before they need admission. Problem drinking The National Treatment Agency for Substance Misuse (NTA), a special authority within the NHS, has published a critical appraisal of the evidence for various treatments for alcohol problems (www.nta.nhs.uk). The 212-page document estimates that over seven million hazardous or harmful drinkers may benefit from brief interventions by any health workers, and over one million dependent drinkers may benefit from specialist intervention. It concludes that cognitive behavioural approaches to specialist treatment are most effective and that treatment probably accounts for about one-third of improvements made in problem drinking. of patients remained on the same treatment after one year, falling to half at two years and about 40 per cent at three years. Treatment was more frequently stopped for lack of efficacy than for adverse effects. Stopping anti-TNFs Discontinuation of treatment with anti-TNF agents is more common in clinical practice than in clinical trial populations, a French study has found (J Rheumatol 2006;33:2372-5). The retrospective analysis of a single centre's experience of treating 770 patients with etanercept (Enbrel), infliximab (Remicade) or adalimumab (Humira) found that fewer than two-thirds of patients remained on the same treatment after one year, falling to half at two years and about 40 per cent at three years. Treatment was more frequently stopped for lack of efficacy than for adverse effects. There were no statistically significant differences between the three agents but there was a trend for infliximab to be least well tolerated. Generic statin savings The Department of Health has estimated that prescribing simvastatin and pravastatin generically would save £85 million per year. Its analysis of the ,Better care, better value' indicators (see www.productivity.nhs.uk) shows that statin prescribing has increased by 150 per cent in the past five years, with costs totalling £600 million in 2005. The Department says that if every PCT prescribed pravastatin and simvastatin by generic name in only 69 per cent of cases ,the level achieved by the top quarter of trusts ,the savings would be over £85 million a year. Herceptin reporting Press reports of a two-year trial of trastuzumab (Herceptin) were generally accurate in reporting its effectiveness but few reported an increased risk of adverse effects, according to the NHS National Library for Health (www.library.nhs.uk). The Herceptin Adjuvant (HERA) trial (Lancet 2007;369:29-36) found that, after an average follow-up of two years, 3 per cent of women treated with trastuzumab died compared with 5 per cent of controls; estimated three-year survival rates were 92.4 and 89.7 per cent respectively. All four press articles reported these findings accurately, but only two mentioned the increased risk of adverse effects. Updated guidance on CDs The Department of Health has published updated guidance on the strengthened governance requirements for managing controlled drugs, taking into account new regulations that came into force on 1 January (seewww.dh.gov.uk/asset Root/04/14/16/67/04141667.pdf). Statin adherence lowers MI mortality Patients with acute myocar- dial infarction (MI) who take their statins as prescribed are significantly more likely to survive for two to three years than those with low adherence (J Am Med Assoc 2007;297: 177-86). The four-year observational study of 31 455 patients with acute MI found that, compared with those who had taken at least 80 per cent of prescribed daily doses, the risk of death in those with less than 40 per cent adherence was 25 per cent greater over 2.4 years. For individuals with intermediate adherence (40-79 per cent), the risk was 12 per cent greater. Both differences were statistically significant after adjustment for potential confounding factors. The authors believe their finding is explained by differences in adherence rather than healthier behaviour because the excess risk of low adherence was less marked with beta-blockers and not significant for calcium-channel blockers. Improving community medicines management Mental health trusts need to improve medicines management by their community teams and improve information sharing with GPs, the Healthcare Commission has found (www.healthcare commission.org.uk). Its national report revealed limited evidence of pharmacist involvement in community mental health teams, even though 90 per cent of patients were cared for in the community. Only 11 per cent of assertive outreach patients had the tests necessary to ensure safe use of their medicines. Medication reviews found that 46 per cent of patients in mental health trusts and 12 per cent of those in acute trusts were not taking their medication appropriately. The Commission also reported that acute trusts received a complete drug history from GPs for fewer than half of audited patients when they were admitted to hospital, and only 30 per cent of PCTs reported that GPs received adequate information on patients' medicines on discharge.

    Antibody screening database for protein kinetic modeling

    PROTEINS: STRUCTURE, FUNCTION AND BIOINFORMATICS, Issue 18 2007
    Brett Spurrier
    Abstract Knowledge-based proteomic studies rely on the availability of quality antibodies. The increasing number of commercially available antibodies covers a wide range of protein networks; however, performance of each antibody can vary, depending on what type of cells, treatments, and time points are studied. Here, we describe an antibody database in which we screened 279 antibodies against multiple cell lysates after various treatments and from different time points. We applied these quality-confirmed antibodies on protein arrays, showing their utility for protein kinetic modeling. [source]

    The Treatment of Sleep-Related Painful Erections

    THE JOURNAL OF SEXUAL MEDICINE, Issue 4 2008
    Mels F. Van Driel PhD
    ABSTRACT Introduction., As specialists in male genital problems, urologists and sexologists will most likely to be involved in the treatment of males presenting with sleep-related painful erections (SRPEs). This means that this phenomenon needs to be recognized by urologists and sexologists, and that they should have knowledge of the current diagnostic and therapeutic approaches. Aim., To review the literature on SRPE and to find the best pharmacological treatment. Methods., Four personal clinical observations from two clinics and 29 other cases with SRPE found in PubMed were analyzed, especially regarding the results of pharmacological treatment. Main Outcome Measures., The results of pharmacological treatment. Results., Many of the various treatments proved to be ineffective and only a few showed efficacy for a few weeks or months. The only effective drugs in the long term were baclofen, clonazepam, and clozapine. Conclusions., Until now, the phenomenon of SRPE is not well understood. The rarity of the published cases undoubtedly does not reflect the actual occurrence of SRPE. Controlled double-blind pharmacological trials are needed, and long-term follow-up including polysomnography coupled with nocturnal penile tumescence and rigidity monitoring may provide further information about SRPE. van Driel MF, Beck JJ, Elzevier HW, van der Hoeven JH, and Nijman JM.

    Development of a Novel Whey Beverage by Fermentation with Kefir Granules.

    BIOTECHNOLOGY PROGRESS, Issue 4 2004
    Effect of Various Treatments
    The development of a novel whey-based beverage with acceptable organoleptic properties is reported, where various treatments were studied. Kefir yeast immobilized on delignified cellulosic materials (DCM) or gluten pellets proved to accelerate whey fermentation significantly, with the latter support being not so preferable. Kefir granules seemed to achieve similar fermentation times as DCM. The final pH of the product is suggested to be 4.1 since the profile of the volatile byproducts was higher than other pH values tested. The addition of fructose seemed to be beneficial on the volatile content of the product, although its acceptability as determined by a preference panel was similar to that of the control. Finally, black raisin extract appeared to promote fermentation without any positive effect on the preference of the evaluators. [source]

    Limits of the applicability and generalizability of drug trials in mania

    BIPOLAR DISORDERS, Issue 2002
    Rasmus W Licht
    Licht RW. Limits of the applicability and generalizability of drug trials in mania. Bipolar Disord 2002: 4(Suppl. 1): 66,68. ©Blackwell Munksgaard, 2002 During recent years, the majority of drug trials in mania have been conducted for the purpose of drug approval. On this background, this paper addresses to what extent these trials may actually provide the practising clinician with useful information. One major point is that selection prior to the point of randomization in RCTs in mania may limit the applicability of study results to patients seen in ordinary clinical practice. Limitations in study credibility and study design are also discussed. The need for large scale pragmatic studies using broad inclusion criteria, comparing the various treatments, alone or in combination, is emphasized. [source]
