Primary effusion lymphoma (PEL) is a distinct type of lymphoma associated with Kaposi's sarcoma-associated herpesvirus (KSHV) infection. To determine the factors responsible for the unrestrained proliferation of PEL, we have studied the growth factor requirements of the PEL-derived BCBL-1 and BC-1 cell lines. Both cell lines were found to be autocrine growth factor dependent and to release huma...

In [4] a nonmonotonic formalism called partial equilibrium logic (PEL) was proposed as a logical foundation for the well-founded semantics (WFS) of logic programs. PEL consists in de ning a class of minimal models, called partial equilibrium (p-equilibrium), inside a non-classical logic called HT 2. In [4] it was shown that, on normal logic programs, p-equilibrium models coincide with Przymusin...

Primary effusion lymphoma (PEL) is an aggressive and rare malignancy predominantly occurring in patients with HIV infection and severe immunodeficiency. PEL has also been reported in recipients of solid organ transplants and in elderly patients in the absence of immunodeficiencies. PEL is a distinct subtype of B-cell non-Hodgkin lymphoma (NHL) characterized by lymphomatous effusions within majo...

The history of sheep scab is briefly discussed since it was first mentioned in 180 BC. It was probably introduced to South Africa by the early settlers and was mentioned as a problem by Simon van der Stel, although its cause was only discovered in 1809. Various measures taken over the centuries to control or eradicate the disease, which has always been of considerable economic importance, are d...

EXTENDED ABSTRACT Hexavalent chromium [Cr(VI)] has long been recognized as a potential carcinogen, via the inhalation route while nowadays, there is an increasing concern that Cr(VI) is also carcinogenic by the oral route of exposure. According to this, governments apply more stringent regulations for chromium species. There are several discussions and intentions to lower the current maximum pe...

  Background: Exposure to respirable particulate matter containing silica in the working environment can lead to respiratory diseases and other health hazards. The current study was designed to estimate the prevalence of lung diseases and their determining factors in the stone carvers of Kerman, Iran.   Materials and Methods: This was a cross-sectional study in which 67 male worker...

This article reviews the available data on the carcinogenicity of formaldehyde from experimental and epidemiologic studies and makes recommendations for further research. Two definitive chronic inhalation bioassays on rodents have demonstrated that formaldehyde produces nasal cancer in rats and mice at 14 ppm and in rats at 6 ppm, which is within the domain of present permissible human exposure...
