Three different rapid strip tests: TRU RSV, BinaxNOW RSV and RSV Respi-strip were compared with RT-PCR and ELISA BRSV Ag for the ability to detect bovine respiratory syncytial virus (BRSV) in nasal swabs collected from calves experimentally vaccinated with live vaccine Rispoval RS-PI3. The reference strains of BRSV (375 and A51908) were detected by ELISA BRSV Ag whereas the strains of human res...

Background : Detection of biomarkers, such as galactomannan (GM), has proven to be great significance in early recognition invasive aspergillosis (IA). The aim our study was evaluate the lateral flow assay (LFA) for detection GM on serum and bronchoalveolar lavage (BAL) samples previously positive by enzyme-linked immunosorbent (ELISA). Methods: performed BAL obtained from patients with suspect...

The display of repertoires of human antibody (Ab) fragments on fila mentous phages and selection by binding of the phage to antigen (Ag) have provided a ready means of deriving human Ab against purified Ag. However, it has been more difficult to obtain phage Ab against an indi vidual Ag of a complex mixture, such as cell surface Ag. Using the technique of "guided selection," we generated human ...

One mechanism by which viral tropism may be controlled is by the expression of a specific virus receptor on the cell surface. This paper reports the identification of a putative cellular receptor for visna virus, the prototype virus of the family Lentiviridae. Using a virus overlay protein blot assay we identified a group of polypeptides of apparent Mr 30K to 33K which interacts with visna viru...

The display of repertoires of human antibody (Ab) fragments on filamentous phages and selection by binding of the phage to antigen (Ag) have provided a ready means of deriving human Ab against purified Ag.

Thrombin activable fibrinolysis inhibitor antigen levels (TAFI Ag ) exhibit a great inter-individual variability in healthy populations. Our aim is to determine whether variability is due to physiologic variations depending on genetic control or due to validation of the method,in order to allow a better interpretation of the results inpatients with vascular diseases. With this purpose, we perfo...

Treatment of patients with coeliac disease with a low gluten containing diet (LGD) remains controversial. We have studied jejunal morphology and antigluten (AG) antibody titres by ELISA in patients on a LGD of 2.5-5 g/day for three to 14 months (median six months) and compared results with patients on a strict gluten free diet (GFD) for six to 27 months (median 13 months). We found no significa...

Atrophic gastritis (AG) is a well-recognized high-risk condition for developing gastric cancer (GC). Gastrin 17 (G17), a hormone secreted from antral G cells, regulates gastric acid secretion, and its serum level is a possible indicator of antral atrophy. Serum pepsinogen is well established as the indicator of AG involving the corpus. Here we investigated whether serum PG and G17 levels would ...
