Selected AbstractsThe mitochondrial genome of the Mediterranean fruit fly, Ceratitis capitataINSECT MOLECULAR BIOLOGY, Issue 2 2000L. Spanos Abstract The complete sequence of the mitochondrial genome of Ceratitis capitata has been determined. The circular genome is 15 980 bp long and contains a standard gene complement, i.e. the large and small ribosomal RNA subunits, twenty-two transfer RNA (tRNA) genes and thirteen genes encoding mitochondrial proteins. When comparing the sequence to fragments previously sequenced from other isolates it becomes apparent that interstrain polymorphisms are not rare. These differences are potentially useful for the development of diagnostic tools for population analysis applications, such as determining the source of recent introductions. Moreover, they could help obtain a solution to the long-lasting controversy on the possible eradication of the Medfly from certain locations. [source] Histopathological features of flexural melanocytic nevi: a study of 40 casesJOURNAL OF CUTANEOUS PATHOLOGY, Issue 5 2000Franco Rongioletti Melanocytic nevi in certain locations such as the genital and acral sites may have atypical histologic features simulating melanoma. We studied the microscopic findings of 40 melanocytic nevi of flexural sites (axilla, umbilicus, inguinal creases, pubis, scrotum and perianal area) to verify if flexural nevi show distinctive features similar to melanocytic nevi of the genital skin. The patients were young (mean age 20 years), the lesions were mostly removed for cosmetic reasons and we are not aware of any deaths or complications related to the removed nevi. We found that 22 (55.5%) out of 40 flexural nevi had "a nested and dyshesive pattern" similar to the melanocytic nevi of genital skin. This pattern was characterized by the confluence of enlarged nests with variation in size, shape and position at the dermo-epidermal junction and by the diminished cohesion of melanocytes. Dermatopathologists should pay attention to the "nested and dyshesive pattern" of flexural nevi that may mimick hystologic changes of melanoma.

Management of AD must consider the symptomatic variability of the disease. Methods, EADV eczema task force developed its guideline for atopic dermatitis diagnosis and treatment based on literature review and repeated consenting group discussions. Results and Discussion, Basic therapy relies on hydrating topical treatment and avoidance of specific and unspecific provocation factors. Anti-inflammatory treatment based on topical glucocorticosteroids and topical calcineurin antagonists is used for exacerbation management and more recently for proactive therapy in selected cases. Topical corticosteroids remain the mainstay of therapy, but the topical calcineurin inhibitors, tacrolimus and pimecrolimus are preferred in certain locations. Systemic anti-inflammatory treatment is an option for severe refractory cases. Microbial colonization and superinfection may induce disease exacerbation and can justify additional antimicrobial/antiseptic treatment. Systemic antihistamines (H1) can relieve pruritus, but do not have sufficient effect on eczema. Adjuvant therapy includes UV irradiation preferably of UVA1 wavelength or UVB 311 nm. Dietary recommendations should be specific and given only in diagnosed individual food allergy. Allergen-specific immunotherapy to aeroallergens may be useful in selected cases. Stress-induced exacerbations may make psychosomatic counselling recommendable. ,Eczema school' educational programmes have been proven to be helpful. [source] Impact of sorghum processing on phytate, phenolic compounds and in vitro solubility of iron and zinc in thick porridgesJOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE, Issue 5 2007AP Polycarpe Kayodé Abstract This study focussed on the impact of process variables on levels of phytate and phenolic compounds, and in vitro solubility of iron (Fe) and zinc (Zn) in sorghum porridges, a major staple in semi-arid tropics. The aim was to identify practices that enhance the mineral availability in this type of staple food. We studied the example of the West African porridge ,dibou' for which the processing methods involve grain cleaning, milling, sieving and cooking. Regional variations occur in the process, particularly in the cleaning which may be done wet or dry; sieving may be omitted in certain locations. Cleaning reduced the phytate content of the grain by 24,39%, while milling, sieving and cooking had no significant effect on phytate. Phenolic compounds measured as levels of reactive hydroxyl groups, remained constant after cleaning, milling and sieving, but significantly decreased by 38,65% after cooking. The Fe solubility tended to increase after cleaning but was drastically reduced due to cooking, and so was the soluble Zn. Levels of total phenolic compounds highly correlated with the Fe and Zn solubility (r2 = 0.73 and 0.82, respectively). Phenolic reaction products formed during the cooking process are presumably related with the extensive browning phenomenon observed in the dibou porridge, and with the reduction observed in Fe and Zn solubility.
