Proton 2D-NOE spectroscopy has been used to investigate the three-dimensional conformations of several sonicated polydeoxynucleotides in solution. The observed pattern of cross peaks indicate that poly(dAdT) . poly(dAdT1 in all salt concentrations studied (up to 6.6M CsF), and poly(dG-m5dC) . poly(dG-m5dC) in low salt (0.1M NaCU are righthanded B-structures. Poly(dG-m5dC) . poly(dG-m5dC) in Mg2...

The necessity of Distributed Generation (DG) in the modern power system has increased greatly. Optimal placement and sizing DGs have a significant impact on objectives voltage stability enhancement, real reactive loss minimization security reliability. Different types such as Type I, II, III IVare placed. optimal these is found using Voltage Stability Index (VSI). done Differential Evolution (D...

10.1601/nm.2199 CLST is an extremely acidophilic gamma-proteobacteria that was isolated from the Gorbea salt flat, an acidic hypersaline environment in northern Chile. This kind of environment is considered a terrestrial analog of ancient Martian terrains and a source of new material for biotechnological applications. 10.1601/nm.2199 plays a key role in industrial bioleaching; it has the capaci...

چکیده: حضور منابع تولید پراکنده (dg) در سیستم قدرت در مقابل مزایای اقتصادی آن، می­تواند باعث ایجاد عدم هماهنگی در عملکرد رله­های اضافه جریان گردد. در این مقاله شاخص جدیدی، مستقل از تنظیمات رله­ها، به منظور تعیین میزان تأثیر نصب dg بر قیود هماهنگی رله­های اضافه جریان ارائه گردیده است. در صورت حضور منابع تولید پراکنده در شبکه، جریان خطای عبوری از رله­های پشتیبان و اصلی نسبت به حالت عدم حضور آن من...

In this study, we aimed to investigate modulation of glucose uptake by the HTR-8/SVneo human first-trimester extravillous trophoblast cell line by a series of compounds and to study its consequences upon cell proliferation, viability and migration. We observed that uptake of (3)H-deoxy-d-glucose ((3)H-DG; 10 nM) was time-dependent, saturable, inhibited by cytochalasin B (50 and 100 µM), phloret...

Dried distiller’s grains (DG) produced from ethanol fermentations dosed with 0 (control), 2, or 20 mg/kg virginiamycin-based product or spiked with virginiamycin (VM) postfermentation were fed to cattle and effects on antimicrobial susceptibility, and prevalence of antimicrobial resistance genes in commensal bacteria was examined. Biological activity assays of DG (from each fermentation) indica...

O-Linked glycosylation is a functionally and structurally diverse type of protein modification present in many tissues and across many species. α-Dystroglycan (α-DG), a protein linked to the extracellular matrix, whose glycosylation status is associated with human muscular dystrophies, displays two predominant types of O-glycosylation, O-linked mannose (O-Man) and O-linked N-acetylgalactosamine...

The binding of ethidium bromide (EtdBr) to the dC-dG-dC-dG self-complementary duplex has been monitored at the resolvable drug and nucleic acid protons and backbone phosphates at high nucleotide/drug (N/D) ratios by nuclear magnetic resonance (NMR) spectroscopy in aqueous solution. We observe averaged resonances (25 degrees-95 degrees) for the nucleic acid and drug nonexchangeable protons in th...

The carcinogen 2-acetylaminofluorene forms two major DNA adducts: N-(2'-deoxyguanosin-8-yl)-2-acetylaminofluorene (dG-AAF) and its deacetylated derivative, N-(2'-deoxyguanosin-8-yl)-2-aminofluorene (dG-AF). Although the dG-AAF and dG-AF adducts are distinguished only by the presence or absence of an acetyl group, they have profoundly different effects on DNA replication. dG-AAF poses a strong b...
