Introduction & Objective: -cells, especially CD8+ T lymphocytes are the most important cells in anti-tumor response. Previously R10 fraction of garlic extract was reported as an immuno-modulator which induced an effective cellular immunity and Th1 responses. In this study the in vitro immunomodulatory effect of R10 on CD8+ T cells viability and production of TNF-α were evaluated. Materials & ...
Research into antiviral agents directed at hepatitis C virus (HCV) proteins is commonly based and tested on a single genotype, namely, genotype 1. This is despite the high level of variability of the RNA virus and the frequency of infection with genotypes other than genotype 1. The systematic evolution of ligands by exponential enrichment (SELEX) is a novel in vitro approach used in this study ...
NGST is capable of reaching the main sequence turnoff of the oldest stellar populations (MV = +4.5) out to a distance ≈ 2 Mpc. There is now evidence that the oldest, most metal poor star clusters are coeval to within 1 Gyr over a 200 kpc radius centered on the Milky Way. NGST can be used to make an equally definitive test of this in the halo and globular cluster system of M31, NGC 147, 185, and...
The basal respiration rate at 10°C (R10) and the temperature sensitivity of soil respiration (Q10) are two premier parameters in predicting the instantaneous rate of soil respiration at a given temperature. However, the mechanisms underlying the spatial variations in R10 and Q10 are not quite clear. R10 and Q10 were calculated using an exponential function with measured soil respiration and soi...
Since ‘nice’ and ‘interesting’ can hardly be treated as mathematically formulated features, let us discuss the permutability property. We shall explain it in more detail for the classical example of surfaces with constant negative Gaussian curvature (K-surface) with their Bäcklund transformations. Let r : R → R be a K-surface, and r10 and r01 two K-surfaces obtained by Bäcklund transformations ...
1. The thermal dependence of passive electrical properties was determined for twitch fibres from the white region of the iliofibularis (IF) muscle of Anolis cristatellus (15-35 degrees C) and Sceloporus occidentalis (15-40 degrees C), and for twitch fibres from the white (15-45 degrees C) and red (15-40 degrees C) regions of the IF of Dipsosaurus dorsalis. These species differ in thermal ecolog...
Background and Objective: Due to the effect of garlic on immune system and a relationship between immune responses and pregnancy outcome, we designed this study to evaluate the effect of immunomodulator fraction of garlic (R10) on main parameters in pregnancy period. Materials and Methods: One week after mating of 30 female BALB/c mice, they were divided into four groups: one group received R10...
Hepatitis A virus (HAV) infects ∼1.4 million people annually and, although there is a vaccine, there are no licensed therapeutic drugs. HAV is unusually stable (making disinfection problematic) and little is known of how it enters cells and releases its RNA. Here we report a potent HAV-specific monoclonal antibody, R10, which neutralizes HAV infection by blocking attachment to the host cell. Hi...
در این مطالعه جداسازی فراکشن های سمی زهر نماتوسیت عروس دریایی Crambionella orsini، که از گونه‌های رایج در خلیج فارس است، با دو روش متفاوت کروماتوگرافی آنیونی و ژل فیلتراسیون صورت گرفت و سپس هر دو کروماتوگرافی مقایسه گردید. سم این گونه از عروس دریایی همانند گونه‌های دیگر دارای خاصیت همولیتیک می‌باشد.پس از فرایند استخراج سم از نماتوسیت‌های موجود در تنتاکول‌ها و لبه‌های چتر این گونه ، سم خام...
مقدمه و هدف: سرطان ها از مشکلات مهم جوامع هستند. در سال های اخیر فراورده های گیاهی برای یافتن اثرات ضدسرطانی و ایمونومدولاتوری مورد توجه قرار گرفته اند. sim5 یک فراوردۀ گیاهی است که اثرات افتراقی قابل توجهی بین سلول های سالم و رده های سرطانی داشته است؛ ولی تابه حال مستقیماً بر روی سلول های بیماران بررسی نشده است. در این مطالعه اثر sim5 بر سلول های مونونوکلئر جداشده از مغز استخوان بیماران مالتیپل...
