Six inorganic-organic bismuth 2,6-pyridinedicarboxylate (pdc) compounds, [Bi(2,6-pdc)(3)]·3(dma), 1, [Bi(2,6-pdc)(3)]·3(dma)·2(H(2)O), 2, [Bi(2,6-pdc)(2)(dmf)]·(dma), 3, Bi(2,6-pdc)(2,6-pdcme)(MeOH), 4, [LiBi(2,6-pdc)(3)(H(2)O)]·2(dma), 5, and Li(5)Bi(2,6-pdc)(4)(H(2)O)(2), 6 (where dma = dimethyl ammonium cation, dmf = dimethylformamide and 2,6-pdcme = 6-methyl-oxycarbonyl pyridine 2-carboxyla...
The function of plasmacytoid dendritic cells (PDC) in chronic human immunodeficiency virus type 1 (HIV-1) infection remains controversial with regard to its potential for sustained alpha interferon (IFN-alpha) production and induction of PDC-dependent tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL)-mediated cytotoxicity of HIV-infected cells. We address these areas by a st...
عملیات خاک ورزی در حدود نیمی از انرژی مورد نیاز برای تولید محصول را به خود اختصاص می دهد. طراحی ادوات خاک ورزی، مستلزم تخمین مناسب نیروهای وارده از طرف خاک به این ادوات می باشد. تاکنون روش های متفاوتی از جمله روش های تحلیلی، تجربی و انواع روش های عددی برای تعیین بر هم کنش تیغه و خاک مورد بررسی قرار گرفته است. بنا به تحقیقات انجام گرفته، برای مواد گرانوله مانند خاک، روش عددی المان مجزا (dem) از ...
Pyruvate decarboxylase (PDC) was purified from mature, dry maize kernels and from roots of anaerobically treated maize seedlings and partially characterzed. PDC was purified to a specific activity of 96 units per milligram protein from kernels and to 41 units per milligram protein from root. The subunit molecular masses were estimated to be 61,000 and 60,000 for kernel PDC and 59,000 and 58,000...
The nucleotide-binding oligomerization domain (NOD)2/CARD15 protein, which senses muramyl dipeptide (MDP), a product of bacterial peptidoglycan, appears to play an important role in regulating intestinal immunity. Although the liver is exposed to gut-derived MDP, the influence of NOD2 ligation on hepatic APC, in particular dendritic cells (DC), is unknown. Freshly isolated mouse liver and splee...
We report in this study the generation of a novel rat mAb that recognizes mouse plasmacytoid dendritic cells (pDC). This Ab, named 120G8, stains a small subset of CD11c(low) spleen cell with high specificity. This population produces high amounts of IFN-alpha upon in vitro viral stimulation. Both ex vivo- and in vitro-derived 120G8(+) cells display a phenotype identical with that of the previou...
We established six T cell clones specific for pyruvate dehydrogenase complex (PDC)-E2 peptides from four different patients with primary biliary cirrhosis using 33 different peptides of 17-20 amino acid residues corresponding to human PDC-E2 as stimulating antigens. The minimal T cell epitopes of these six T cell clones were all mapped to the same region of the PDC-E2 peptide 163-176 (GDLLAEIET...
BACKGROUND The twin problem of shortage in fossil fuel and increase in environmental pollution can be partly addressed by blending of ethanol with transport fuel. Increasing the ethanol production for this purpose without affecting the food security of the countries would require the use of cellulosic plant materials as substrate. Clostridium thermocellum is an anaerobic thermophilic bacterium ...
Plasmacytoid dendritic cells (PDC), the main producers of type I IFNs in the blood, are important for the recognition and control of viral and bacterial infections. Because several viruses induce IFN-alpha production, severe courses of herpes virus infections in nonimmunocompromised patients may be related to numerical or functional PDC deficits. To evaluate this hypothesis, PBMC and PDC were r...
ترانسفورماتور قدرت یکی از تجهیزات حیاتی در شبکه برق است. افزایش رطوبت در سیستم عایقی ترانسفورماتور موجب کاهش قدرت دی الکتریک، کاهش ولتاژ شکست، بروز تخلیه جزئی و کاهش چشمگیر عمر ترانسفورماتور بواسطه تخریب بافت کاغذ خواهد شد. در این تحقیق استفاده از روش اندازه گیری جریان های پلاریزاسیون و دیپلاریزاسیون (pdc) به منظور تخمین رطوبت کاغذ در مدل سیستم عایقی در سه دمای مختلف بررسی شده است. با هر پله...
