We have sequenced serum albumin cDNA from liver of the Mongolian gerbil, Meriones unguiculatus. The deduced amino acid sequence showed 82.6% and 73.6% identity with the corresponding proteins from rats and humans, respectively. Identical cDNA was detected in pancreas by reverse transcription followed by polymerase chain reaction (RT-PCR). Further amplification of cDNA by nested PCR revealed the...
مقدمه و هدف: پروتئین وابسته به آگوتی(agrp) یک پپتید اشتها آور قوی است که به میزان زیادی از بخش میانی هستههای کمانی هیپوتالاموس ترشح میشود و در کنترل مرکزی دریافت غذا و اشتها نقشی مهم دارد. مشخصشده که این پپتید در کنترل وزن انسان نقش بسزایی ایفا میکند و سطوح پلاسمایی آن در شرایط گرسنگی و چاقی افزایشمییابد. هدف تحقیق حاضر، بررسی یک دوره تمرین بیهوازی دایرهای بر بیان ژنagrp لنفوسیت کشتیگ...
Ehrlichia chaffeensis is an obligatory intracellular bacterium of monocytes and macrophages and the etiologic agent of human monocytic ehrlichiosis, an emerging zoonosis. The Lone Star tick (Amblyomma americanum) has been implicated as the primary vector of E. chaffeensis. The present study examined the sensitivity of the nested reverse transcription (RT)-PCR based on the 16S rRNA gene relative...
ویروس نکروز عفونی بافت های خونساز (ihnv) یکی از مهمترین ویروس های بیماری زا در ماهی قزل آلا می باشد. ihnv باعث ایجاد اپیدمی بیماری نکروز عفونی بافت های خونساز در ماهیان جوان شده و ماهیان بالغ، حامل این ویروس می شوند. در این مطالعه، 40 نمونه جمع آوری شده از مزارع پرورش قزل آلا در استان خراسان رضوی به روش nested-rt-pcr مورد بررسی قرار گرفت. بافت های کلیه، کبد و طحال ماهیان و همچنین تخم های چشم زد...
Type I trichomes of tomato leaves (Solanum lycopersicum Mill. cv. Moneymaker), as outgrowths the plant epidermis, are suitable for monitoring infection processes powdery mildew species using a high-fidelity digital microscope (DM) without fungal staining. On trichomes, (Pseudoidium neolycopersici L. Kiss) isolate KTP-03 produced maximum four vigorously elongated hyphae per conidium, which stopp...
INTRODUCTION Molecular biology procedures to detect, genotype and quantify hepatitis C virus (HCV) RNA in clinical samples have been extensively described. Routine commercial methods for each specific purpose (detection, quantification and genotyping) are also available, all of which are typically based on polymerase chain reaction (PCR) targeting the HCV 5' untranslated region (5'UTR). This st...
A survey of 158 rodents caught in the Czech Republic identified Dobrava virus sequences closely related to that of the Dobrava virus type strain in Apodemus sylvaticus and Mus musculus rodents. The identity of A. sylvaticus was unequivocally confirmed by random amplified polymorphic DNA analysis. The data seem to indicate hantavirus spillover from Apodemus flavicollis to other rodents.
BACKGROUND & OBJECTIVES Bats are recognized as important reservoirs for emerging infectious disease and some unknown viral diseases. Two novel viruses, Malsoor virus (family Bunyaviridae, genus, Phlebovirus) and a novel adenovirus (AdV) (family, Adenoviridae genus, Mastadenovirus), were identified from Rousettus bats in the Maharashtra State of India. This study was done to develop and optimize...
Abstract. An efficient and rapid virus detection method is required for routine monitoring and risk assessment in food products. A duplex RT-coupled nested PCR method was developed to detect the simultaneous presence of hepatitis A virus (HAV) and rotavirus in commercial oysters from the eastern coast of Thailand. Primers were designed to amplify HAV VP4 and rotavirus VP7 genes. Although excess...
A rapid and sensitive reverse transcription polymerase chain reaction (RT-PCR) and nested-PCR were used to detect bovine viral diarrhea virus 1 (BVDV-1) in bull semen. Selected primers could amplify a part of the 5´UTR of the BVDV genome. A 294 bp DNA fragment was amplified and specificity of the results was confirmed by direct sequencing of the PCR product. Prior to RNA extraction, the seminal...
