AIM Since most forms of Kaposi sarcoma are much more common in men than in women, the aim of this study was to examine serum concentrations of sex steroids in HIV positive men with and without Kaposi sarcoma. METHODS Blood samples from 34 HIV positive men without Kaposi sarcoma (KS-) and 28 with Kaposi sarcoma (KS+) and from 35 HIV negative men (controls) were analysed for adrenal and gonadal...

شرایط افروزش و اشتعال سوخت‌های گداخت هسته‌ای در حضور ناخالص­‌ها، یکی از موارد مهمی است که طراحی قرص‌های سوخت باید مورد توجه قرار گیرد. این مقاله اثر ناخالصی هسته سنگین طلا بر کلیه فرایندهای احتراق پلاسمای غیرتعادلی دوتریم- تریتیم مدل چهار دمایی آن شکل تابع توزیع انرژی رفتار فوتون‌ها تأثیر می‌گذارد بررسی گرفته است. مطالعه شامل اثرات منفی سوخت، طول زمان تشکیل لکه داغ نتایج محاسبات عددی به­ دست آم...

Knowledge sharing (KS) is a challenge for non-governmental organisations (NGOs) given its high turnover and the informal nature of KS. We examine KS in Portuguese NGOs by adopting three levels ...

New and recent measurements of the branching ratios of rare decays of neutral KS and KL mesons are presented. The results have been extracted from data collected during the NA48 ′/ runs as well as in a special high intensity KS and hyperon run. In particular the presentation focuses on the decay of KL → πγγ, KS → π0e+e− and KS → γγ. The prospects of future programs aiming to study direct CP vio...

Kaposi's sarcoma (KS) is an angioproliferative disease characterized by proliferation of spindle-shaped cells predominantly of endothelial cell origin, neoangiogenesis, inflammatory cell infiltration, and edema. At least in early stage, KS behaves as a reactive lesion sustained by the action of inflammatory cytokines and growth factors, has a polyclonal nature, and can regress. However, in time...

BACKGROUND Isolation of the first neoplastic acquired immunodeficiency syndrome-related Kaposi's sarcoma (KS) cell line (KS Y-1) has furthered understanding of the pathogenesis of KS. Studies with KS Y-1 cells have indicated that inhibition of KS cell proliferation occurs in early pregnancy in mice and after treatment with certain commercial preparations of human chorionic gonadotropin (hCG, a ...

Glycosaminoglycans (GAGs), including chondroitin sulfate (CS), dermatan sulfate, heparin, heparan sulfate and keratan sulfate (KS) are linear sulfated repeating disaccharide sequences containing hexosamine and uronic acid [or galactose (Gal) in the case of KS]. Among the GAGs, CS shows structural variations, such as sulfation patterns and fucosylation, which are responsible for their physiologi...
