The complete nucleotide sequence of the mitochondrial (mt) genome of the crab-eating frog, Fejervarya cancrivora Gravenhorst (Amphibia: Anura: Ranidae), was determined. The mt genome is 17,843 bp long and contains 13 protein-coding (ATP6, ATP8, COI-III, ND1-6 and 4L, and Cyt b) and two ribosomal RNA (12S and 16SrRNA) genes. Although metazoan mt genomes typically encode 22 transfer RNA genes (tR...
Tsukamurella spp. are a rare but important cause of intravascular catheter-related bacteremia in immunocompromised patients. The organism is an aerobic, Gram-positive, weakly acid-fast bacillus that is difficult to differentiate using standard laboratory methods from other aerobic actinomycetales such as Nocardia spp., Rhododoccus spp., Gordonia spp., and the rapid growing Mycobacterium spp. We...
مطالعات انجام شده روی مکانیسمهای تکوینی و تکاملی گلبولهای قرمز منجر به دستیابی بشر به مفاهیم پایه و مهمی در ارتباط با مکانیسمهای عمومی تنظیم بیان ژن وشکل گیری بافتها شده است. تمایز اختصاصی به رده ارتیروئید و هر رده دیگری، شدیداً وابسته به تنظیم در سطح بیان ژن و فاکتورهای کنترلی خاص نظیر سیتوکین ها، فاکتورهای نسخه برداری ویژه، عناصر کنترل کننده چرخه سلولی، تکثیر،آپوپتوز و عناصر سیگنالینگ داخل سلو...
background : appropriate methodology for storage biological materials, extraction of dna, and proper dna preservation is vital for studies involving genetic analysis of insects, bacteria, and reservoir hosts as well as for molecular diagnostics of pathogens carried by vectors and reservoirs. here we tried to evaluate the utility of a simple filter paper-based for storage of insects, bacteria, r...
BACKGROUND The presence of enterohepatic Helicobacter species (EHS) is commonly noted in mouse colonies. These infections often remain unrecognized but can cause severe health complications or more subtle host immune perturbations and therefore can confound the results of animal experiments. The aim of this study was to isolate and characterize a putative novel EHS that has previously been dete...
A mixed culture capable of dechlorinating perchloroethylene (PCE) to ethene was analyzed under non steady and pseudo-steady state conditions. Dehalococcoides mccartyi, considered to be the primary dechlorinating bacterium able to completely degrade chlorinated hydrocarbons to non toxic ethene, could be detected by CAtalyzed Reporter Deposition Fluorescence In Situ Hybridization (CARD-FISH) sinc...
