اختیار آسیایی (یا اختیار میانگین) نمونه ای خاص از قرارداد اختیار است، که بازده آن وابسته به میانگین قیمت دارایی پایه در سرتاسر بازه ی زمانی از قبل تعیین شده می باشد. این اختیارات از نمونه های اصلی اختیارات نامتعارف هستند و در بازارهای مالی بسیار مشهورند. یکی از مزایای اختیارات آسیایی این است که می توانند میزان ریسک دستکاری های قیمت را در سررسید و در بازار مالی کاهش دهند. یکی دیگر از مزایای ای...
BACKGROUND The incidence of Kaposi's sarcoma (KS) is increased severalfold in individuals infected with human immunodeficiency virus-1 (HIV). Human herpesvirus 8 (HHV8) has also been implicated in KS. We investigated several factors that may determine the onset of KS, particularly HHV8 infection in individuals after becoming seropositive for HIV. METHODS We studied 366 individuals belonging t...
Escape of tumor cells from apoptotic-mediated stimuli results in tumor cell survival and resistance to cytotoxic mechanisms. Kaposi's sarcoma (KS) is the most common malignancy associated with AIDS, although its pathogenesis is not known. It is clinically important to determine whether AIDS-KS cells are resistant to apoptosis via the Fas system. Three isolates of AIDS-KS cells were studied. Alt...
Twenty years after its discovery [1], Kaposi’s sarcoma herpesvirus (KSHV) or human herpesvirus-8 (HHV-8) continues to be an enigmatic oncovirus, while AIDS-associated Kaposi’s sarcoma (AIDS-KS) remains a clinical challenge in endemic regions in Africa and for some patients receiving anti-retroviral therapy (ART) [2–4]. KSHV, a gamma-2 herpesvirus, is the etiological agent of Kaposi’s sarcoma (K...
Kindler syndrome (KS) is a rare, autosomal recessive genodermatosis characterized by skin blistering and photosensitivity in infancy, progressive poikiloderma, and diffuse cutaneous atrophy. It affects the skin, mucous membranes, and oral cavity and is caused by mutations in the KIND1 gene on 20p12.3. The first case of KS associated with periodontitis was reported in 1996, and have been infrequ...
OBJECTIVE Geographic and racial disparities may contribute to variation in the incidence and outcomes of HIV-associated cancers in the United States. METHOD Using the Surveillance, Epidemiology, and End Results (SEER) database, we analyzed Kaposi sarcoma (KS) incidence and survival by race and geographic region during the combined antiretroviral therapy era. Reported cases of KS in men from 2...
As previously described, proliferation of Kaposi sarcoma (KS)-derived cells in vitro is dependent on the presence of platelet-derived growth factor (PDGF). To test the hypothesis that PDGF may also be a major growth factor for KS cells in vivo, we performed in situ hybridization and immunohistochemical staining for PDGF and PDGF receptors in tissue sections of AIDS-related KS. The data suggest ...
Kaposi sarcoma (KS) is a vascular neoplasm of the endothelial cells that commonly occurs in conditions that may lead to severe immunosuppression, e.g. HIV/AIDS, malignancies or use of immune suppressing medications. The development of KS has been linked to infection with an oncogenic virus, the Human Herpes Virus 8 (HHV-8), also known as KS-associated herpes virus (KSHV). Rarely KS also occurs ...
Recently, DNA sequences of what appear to be a unique human herpesvirus-like agent (HHV-8) have been detected in different types of Kaposi's sarcoma (KS) tumors (Chang, Y., E.C. Cesarman, M.S. Pessin, F. Lee, J.C. Culpepper, D.M. Knowles, and P.S. Moore. 1994. Science (Wash. DC). 266:1865-1869). To further elucidate the possibility that HHV-8 plays a role in the pathogenesis of KS, the expressi...
The ratio of second to fourth digit length (2D:4D) is a correlate of prenatal testosterone. High 2D:4D is associated with low prenatal testosterone, and reduced sensitivity to testosterone. Klinefelter's syndrome (KS; 47 XXY) affects the endocrine system, such that low testosterone levels are found in KS foetuses, new-borns and adults. To date, there are no published data regarding the pattern ...
