Selected AbstractsAnnual Cycle of Planktothrix agardhii(Gom.) Anagn.INTERNATIONAL REVIEW OF HYDROBIOLOGY, Issue 3 2004& Kom. Abstract Changes in abundance, biovolume and morphology of Planktothrix agardhii in a natural population were followed over one year period in shallow fishpond Bílá Lhota (Central Moravia, Czech Republic). The selected environmental parameters (pH, oxygen, temperature, conductivity, nutrients, light) were measured at the surface and at the bottom of the fishpond, together with the Planktothrix abundances and filament morphology , filament length, width, shape, aerotopes (gas vacuoles) formation. The annual cycle of P. agardhii in this hypertrophic fishpond starts in March with the germination of hormogonia and the growth of overwintered filaments. The filament length quickly increases to a maximum length in April. The following summer period can be characterized by filament shortening and by changes in the aerotopes shape. On the other hand the abundance and biomass of P. agardhii is increasing until the maximum in August. Further shortening of filaments, loss of aerotopes and hormogoniae formation is typical for the autumn (October) with the average temperature of 9.4 °C. The population overwinters near the pond bottom in the form of hormogonia (60%) and filaments (40%). (© 2004 WILEY-VCH Verlag GmbH & Co.

Overall, we counted a total of 9134 carcasses from 27 species. This represents a biomass harvest of about 170,000 kg, a figure that could reach 335,100 kg when game consumed by hunters (i.e. not sold) and markets not sampled are taken into account. Ungulates (eleven species) and rodents (four species) accounted for 53.5% and 24.8% of the carcasses counted respectively (80.8% and 11.4% of the total biomass, respectively). The number of carcasses counted in villages bordering a heavily trafficked road was significantly higher than in more rural villages, thus highlighting the stimulating effect of roads on the bushmeat trade. Compared with existing data collected in 1995, the proportion of ungulates counted in the Mansira Moribaya village in 2001 increased significantly while that of rodents decreased significantly. The harvest of duiker species at Mansira Moribaya was in excess of the maximum sustainable harvest. These results of this study were used to establish a sustainable wildlife management scheme in the HNNP. Résumé Pour documenter le commerce de viande de brousse dans la zone tampon du Parc National du Haut Niger, en République de Guinée, nous avons contrôlé le nombre de carcasses proposées à la vente pendant une année (2001) dans 16 villages. En tout, nous avons compté 9 134 carcasses appartenant à 27 espèces. Cela représente un prélèvement de biomasse d'environ 170.000 kg, un chiffre qui pourrait même atteindre 335.100 kg si l'on tient compte de la viande consommée par les chasseurs (c.-à-d. pas vendue) et des marchés qui n'ont pas été repris dans notre échantillon. Les ongulés (11 espèces) et les rongeurs (quatre espèces) représentaient 53,5% et 24,8% des carcasses comptées et comptaient respectivement pour 80,8% et 11,4% de la biomasse totale. Le nombre de carcasses comptées dans les villages longeant une route très fréquentée était significativement plus élevé que dans des villages plus ruraux, ce qui met en évidence l'effet dynamisant des routes sur le commerce de viande de brousse. Comparée aux données existantes récoltées en 1995, la proportion d'ongulés comptés dans le village de Mansira Moribaya en 2001 a augmenté significativement alors que celui des rongeurs a diminué significativement. Le prélèvement des espèces de céphalophes à Mansira Moribaya dépassait le prélèvement maximum soutenable. Les résultats de cette étude ont servi àétablir un programme de gestion durable de la faune sauvage dans le Parc National du Haut Niger.

Kumar Background Coronary revascularization surgery does not traditionally employ angiography to assess procedural success. Early graft failure is reported up to 30% in one year (JAMA Nov 2005) may relate to technical errors or conduit problems. We hypothesize that intra-operative assessment of graft by angiography identifies graft defects and may improve the long term graft survival. Methods We have developed one of the first hybrid operation room in the USA. In one year period 203 consecutive patients (age:63+/,16, M/F:126/39) underwent coronary revascularization with angiography before decannulation. Results Of 436 grafts, 72 angiographic defects were detected in 69 grafts (17% of total grafts). There were 11% conduit defects, 3% anastomotic defects, and 3% target vessel error. Of 72 defects, 25/72 defects required minor revision, 47/72 required either surgical or percutaneous intervention. Intra-operative angiography added an average 20+/,12 minutes to the surgery and 112+/,56 ml contrast. Renal function at 24hours and 48 hours after procedure did not vary significantly between patients who did vs. those did not have revisions. There were no significant differences in cardiopulmonary bypass time, aortic cross clamp time, and length of hospital stay for patients who underwent revision compared to those who did not. Renal function, bleeding complication, transfusion were similar in patients with percutaneous vs. surgical revision. Conclusions Intraoperative graft angiography performed at the time of CABG identifies graft defects, allowing for immediate surgical or percutaneous revision. Long-term study is in progress to assess whether intra-operative completion angiography decreases the rate of early graft failure. [source] The Effect of Oxcarbazepine on Bone MetabolismACTA NEUROLOGICA SCANDINAVICA, Issue 3 2009Y. Çetinkaya Objective,,, Long term use of several antiepileptic drugs is known to cause alteration in bone metabolism. Therefore, we investigated the effect of new antiepileptic drug, oxcarbazepine, on bone metabolism. Methods,,, Twenty eight patients who were on oxcarbazepin therapy (18 female, 10 males; mean age: 27.82 ± 10.98 years (range: 15,45)) with no additional antiepileptic drug use history in one year period prior to the study and 28 control subjects were involved in the study. Measurement of calcium, phosphate, alkaline phosphatase and Vitamin D3 levels and bone density measurements with DEXA method were performed in patient and age-matched control groups. The baseline parameters were compared with the control group and with those measured at the end of one year. Results,,, The biochemical (calcium, phosphate, alkaline phosphatase and Vitamin D3) parameters and densitometry values after one year of therapy were not different than the baseline values indicating that those were not affected by the therapy (P > 0.05). Conclusions,,, In previous studies, anticonvulsant drugs that induce enzymes increase bone degradation by causing vitamin D deficiency. According to the results of this study, oxcarbazepin with little effect on enzyme induction was shown not to affect bone mineral metabolism. [source] | |||||||||||||
