زمینه و هدف: گزارشات مبتنی بر ارتباط بین ویتامین 12b و عملکرد شناختی وجود دارد. در بیماران با کاهش حافظه، اندازه گیری ویتامین 12b سرم به صورت روزمره جهت تشخیص اولیه انجام میشود. با توجه به نقش سیستم کولینرژیک و ویتامین 12b در فرایند حافظه، در تحقیق حاضر اثر میانکنش بین ویتامین 12b و نیکوتین بر به یادآوری حافظه با استفاده شیوه احترازی غیرفعال در موش های صحرایی نر بالغ مورد ارزیابی قرار گرفت. مو...
this study evaluates the effectiveness of adsorption process by granular activated carbon (gac) compared with a novel formulation of coagulation - flocculation process for dye removal from textile wastewater. in this regard, acidic, reactive, disperse and direct red dye are used to prepare the synthetic dye. dominant wave length for each dye is determined by spectrophotometeric method. using ga...
Comparison of homologous angucycline modification enzymes from five closely related Streptomyces pathways (pga, cab, jad, urd, lan) allowed us to deduce the biosynthetic steps responsible for the three alternative outcomes: gaudimycin C, dehydrorabelomycin, and 11-deoxylandomycinone. The C-12b-hydroxylated urdamycin and gaudimycin metabolites appear to be the ancestral representatives from whic...
The integral cross section of the 12C(n, p)12B reaction was measured at the neutron time of flight facility n_TOF at CERN, from the reaction threshold at 13.6 MeV up to 10 GeV, by means of the combined activation and a time-offlight technique. The integral result is expressed as the number of 12B nuclei produced per single pulse of the neutron beam. A simple integral expression is given for cal...
Genetic variants of IL-18 and IL-12B may be important in immunoregulatory abnormalities, observed in the patients with Type 1 diabetes mellitus (T1DM), that contribute to individual differences in response to a treatment. Therefore, we examined the significance of IL-18-137G/C, IL-18-607C/A, and IL-12B A/C polymorphisms in Croatians (187 patients, 236 controls), not only as factors that contrib...
UNLABELLED Dengue virus (DENV) infection usually presents with mild self-limiting dengue fever (DF). Few however, would present with the more severe form of the disease, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). In the present study, the association between IL-12B, IL-10 and TNF-α gene polymorphisms and dengue severity was investigated. METHODS A case-control study was p...
Interleukin 12 (IL-12) is a heterodimeric, pro-inflammatory cytokine that plays a central role in activation and differentiation of CD4(+) T cells into interferon-γ secreting T-helper type 1 cells. IL-12B, a gene encoding the larger subunit of active IL-12, has been reported to be down-regulated by the nuclear hormone 1α,25-dihydroxyvitamin D(3) (1α,25(OH)(2)D(3)), but the mechanism of the regu...
IL-12 has been reported to affect thymic T cell selection, but the role of IL-12 in thymic involution has not been studied. We found that in vivo, IL-12b knockout (IL-12b(-/-)) mice exhibited accelerated thymic involution compared with wild-type (WT) B6 mice. This is characterized by an increase in thymocytes with the early development stage phenotype of CD25(-)CD44(+)CD4(-)CD8(-) in aged IL-12...
A series of tribenzotriquinacene derivatives bearing three oxy-functionalised alkyl groups at the benzhydrylic bridgeheads (C-4b, C-8b and C-12b) have been synthesised. The 4b,8b,12b-triallyl derivative was used to generate the corresponding TBTQ-tris-acetaldehyde and TBTQ-tris(acetic acid), in which the functional groups stretch out from the convex rigid molecular surface. The corresponding tr...
سابقه و هدف: ویتامین 12b یکی از ضروری ترین ویتامین های مورد نیاز بدن می باشد. تظاهرات روان پزشکی بیماران دچار کمبود ویتامین 12b اغلب شامل پرخاشگری و بی قراری به همراه تحریک پذیری و گیجی، اختلال در جهت یابی، فراموشی، اختلال در تمرکز و توجه، بی خوابی، بی اشتهایی می باشد. تاخیر در درمان بیماری کمبود ویتامین 12b ممکن است باعث عوارض غیر قابل برگشت در ساختار مغز گردد. در این یک مورد بیمار مبتلا به کم...
