A modern biomedical research project can easily contain hundreds of analysis steps and lack of reproducibility of the analyses has been recognized as a severe issue. While thorough documentation enables reproducibility, the number of analysis programs used can be so large that in reality reproducibility cannot be easily achieved. Literate programming is an approach to present computer programs ...
نگرانی در مورد حفاظت از محیط زیست در جهان در حال افزایش است. امروزه، گسترش تیمارهای جداسازی آلایندهها به وسیله فرآیند جذب در شیمی زیست محیطی به دلیل هزینههای پایین آن، سادگی طراحی، سهولت عملیات، عدم حساسیت به مواد سمی وحذف کامل آلایندهها گسترش جهانی یافته است. با تحول مدل سازی همدما، علاقه رو به رشدی در این زمینه پژوهشی به وجود آمده است. در تایید این ادعا، مقاله حاضر به بررسی هنر مدل سازی ه...
The nonclassical class I MHC molecule HLA-G is selectively expressed on extravillous cytotrophoblast cells at the maternal-fetal interface during pregnancy. HLA-G can inhibit the killing mediated by NK cells via interaction with the inhibitory NK cell receptor, leukocyte Ig-like receptor-1 (LIR-1). Comparison of the sequence of the HLA-G molecule to other class I MHC proteins revealed two uniqu...
Immunoglobulin (Ig) function varies by isotype and antibody activity is best mediated by isotypes most able to control the inciting infection. In pigs, a high ratio of IgG1:IgG2 is associated with resistance to disease caused by the extra-cellular bacterium Actinobacillus pleuropneumoniae. This ratio is controlled by type 1/type 2 cytokines in vitro, reflecting cell- (CMI) or antibody-mediated ...
Protein aggregation is associated with age-related neurodegenerative disorders, such as Alzheimer's and polyglutamine diseases. As a causal relationship between protein aggregation and neurodegeneration remains elusive, understanding the cellular mechanisms regulating protein aggregation will help develop future treatments. To identify such mechanisms, we conducted a forward genetic screen in a...
The inhibitory molecule CD85/LIR-1/ILT2 has been detected previously on the surface of a small proportion of T lymphocytes. In this study, evidence is provided that, although only a fraction of CD3+ cells are stained by mAb specific for CD85/LIR-1/ILT2 on their surface, this inhibitory receptor is present in the cytoplasm of all T lymphocytes, and that it is detectable on the surface of all T c...
جواب های معادلات انتگرال منفرد (sies) مشخصه بر حسب انتگرال های منفرد نوع کوشی با تابع وزن بیان می شود. قواعد انتگرال گیری جدیدی را برای تقریب تمامی جواب های معادله انتگرال منفرد مشخصه نوع کوشی روی بازه $ [-1,1] $ معرفی می کنیم. تخمین خطاها در کلاسی از توابع $ h^{alpha} ([-1,1], a) $ و $ c^1 ([-1,1]) $ بیان می شود. نتایج عددی حتی برای حالت های نیمه کراندار و بی کران از جواب های انت...
In the sea slug Tritonia diomedea, mucociliary crawling is controlled partly by two pairs of bilaterally symmetrical neurons located in the pedal ganglia. These neurons, known as the Pedal 5 and Pedal 6 cells, produce a class of neuropeptides called TPeps. Using immunohistochemistry we identified TPep-like immunoreactive (TPep-LIR) neurons in diverse nudibranch species. All species examined had...
The infrared (IR) emission plays a crucial role for understanding the star formation in galaxies hidden by dust. We first examined four estimators of the IR luminosity of galaxies, LFIR (Helou et al. 1988), LTIR (Dale et al. 2001a), revised version of LTIR (Dale & Helou 2002) (we denote LTIR2), and LIR (Sanders & Mirabel 1996) by using the observed SEDs of well-known galaxies. We found that LIR...
