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...
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...
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...
BACKGROUND Chandipura virus (CHPV), a member of family Rhabdoviridae was attributed to an explosive outbreak of acute encephalitis in children in Andhra Pradesh, India in 2003 and a small outbreak among tribal children from Gujarat, Western India in 2004. The case-fatality rate ranged from 55-75%. Considering the rapid progression of the disease and high mortality, a highly sensitive method for...
Water samples were concentrated by the modified adsorption-elution technique followed by speedVac reconcentration of the filter eluates. Reverse transcriptase-nested polymerase chain reaction (RT-nested PCR) was used to detect rotavirus RNA in concentrates of the water. The detection limit of the rotavirus determined by RT-nested PCR alone was about 1.67 plaque forming units (PFU) per RT-PCR as...
