PURPOSE The purpose of our study was to detect circulating malignant cells (CMCs) in oversea-shipped blood samples of patients with uveal melanoma diagnosed in Brazil. METHODOS: Melan-A and tyrosinase were the two markers used for the detection of CMCs, using reverse transcriptase nested polymerase chain reaction (RT-nested-PCR) in 6 patients with uveal melanoma. The expression of beta-actin an...
A real-time reverse transcriptase PCR (RT-PCR) assay that targeted both the mumps virus F gene and human RNase P in clinical samples was adapted for use with the LightCycler platform. LightCycler RT-PCR is as sensitive as conventional nested RT-PCR and significantly less expensive and labor-intensive, making it ideal for mumps diagnosis during outbreaks.
Respiratory syncytial virus (RSV) is one of the most important virus respiratory pathogens in infants and young children. A rapid and sensitive diagnosis is essential to focus any outbreak due to this virus. A real-time RT-PCR method was designed using a primer/probe pair from the F gene. Simultaneously with nested RT-PCR and antigen ELISA, 71 consecutive specimens from hospitalized children wi...
background: giardia duodenalis is one of the most important human enteric parasites throughout the world. clinical symptoms of this parasite vary from asymptomatic infection to chronic diarrhea. still it is not clear, whether different types of pathogenesis are due to different strains of organism or to variable host factors. the purpose of this study was to investigate possible correlation of ...
خلاصه: واکنش زنجیره ای پلیمراز یکی از اختصاصی ترین روش های تشخیص تفریقی گونه های آناپلاسما می باشد . واکنش زنجیره ای پلیمراز بر اساس ژن 16s rrna می تواند گونه های جنس آناپلاسما را از یکدیگر تفریق نماید ولی توالی نوکلئوتیدی ژن 16s rrna در آناپلاسما اوویس بسیار شبیه به آناپلاسما مارجیناله می باشد(9/99%تا 2/99%) و طراحی آغازگرهای اختصاصی برای تکثیر این دو گونه غیر ممکن است. گوسفند و بز می توانن...
Bovine viral diarrhoea virus (BVDV) is an important pathogen of dairy cattle. In this study, bulk milk samples representing a total of 4105 milking cows, from 18 dairy cattle herds in the suburb of Mashhad- Iran, were tested for presence of BVDV by the use of a nested reverse transcription polymerase chain reaction (Nested RT- PCR) assay. Non of the cows in the herds had been vaccinated against...
introduction: brain-derived neurotrophic factor (bdnf) and its receptor, trkb, in the hippocampus are targets for adverse effects of stress paradigms in addition, bdnf and its receptor play key role in the pathology of brain diseases like depression. in the present study, we evaluated the possible role of hippocampal bdnf in depression during pregnancy, methods: to achieve the purpose, repeated...
osteosarcoma is a relatively uncommon malignancy however, it is the most common form of primary malignant bone tumors in human. diagnosis and prognosis of patients with osteosarcoma is limited to clinico-radiopathological parameters, whereas molecular markers of tumor aggression have been poorly identified. survivin, an inhibitor of apoptosis (iap), is unique for its expression in human tumors ...
abstract background and aim: survivin is a new member of inhibitor of apoptosis protein family (iap) that plays an important role in the regulation of cell cycle and inhibition of apoptosis. distinct expression of this gene in tumoral cells versus normal cells introduces it as the fourth major transcriptome in cancers. thyroid carcinoma is the most common endocrine malignancy. considering the h...
