few studies have been reported regarding probiotic properties of lactococcus lactis strains although they are extensively used as starter cultures in the production of dairy products. in this study 8 wild isolates of lactococcus lactis were evaluated in vitro with regard to resistance to simulated gastric and intestinal juices, adherence ability to caco-2 cells and ht29-mtx-e12 cell lines, anti...

background: generation of an effective dendritic cell (dc) based cancer vaccine depends on appropriate differentiation of monocytes in vitro. objective: to compare the effects of monocyte separation methods, flask adherence (flask-dc) and magnetic activated cell sorting (macs-dc), on phenotypic and functional characteristics of resultant dcs. methods: dcs from healthy volunteers were generated ...

We have investigated the adherence of Burkholderia pseudomallei, cultured under a number of different conditions, to six human epithelial cell lines. While several complex medium compositions had relatively little effect on adherence, growth at 30 degrees C was found to significantly increase adherence to all cell lines relative to that of cultures grown at 37 degrees C (P < 0.001).

the aim of this work was to see whether tamarin immunisation with recombinant vaccinia virus expressing epstein barr virus latent proteins could prime t cells which were, on activation, able to inhibit the outgrowth of epstein barr virus transformed cells in vitro. the vaccination appeared to be successful as all vaccinated tamarins developed vaccinia lesions. however, the vaccination protocol ...

Human colon carcinoma cell lines that vary in their degree of differentiation were examined for their ability to interact with extracellular matrix components. For this purpose, established cell lines were classified on the basis of several criteria that relate to degree of differentiation. These criteria include histology of the original tumor, histology of xenografts, in vitro morphology, and...

objective(s): artemisia is a genus of herbs and small shrubs forms an important part of natural vegetation in iran. it has been reported that several artemisia species possess anti-proliferative effects. considering the value of this genus in anti-cancer researches we have chosen artemisia biennis for cytotoxic and mechanistic studies. materials and methods:in this study we have investigated th...

Escherichia coli is considered as the main cause of epidemic outbreaks and endemic cases of child diarrhea. In the present study, the capacity of a large collection of Escherichia coli (E. coli) strains and matched controls was investigated to determine their adherence pattern on Hep-2 cell lines. A total of 66 pure E. coli strains, which were previously isolated from children aged less than 12...
