The purpose of the study was to determine the microbiological status of 161 samples cooled and frozen fish products collected from retail markets in the Republic of Bulgaria. The highest total viable counts (TVCs) in cooled fish products were established for silver carp (7.30 log cfu/g), Black sea roach (7.28 log cfu/g) and trout (7.11 log cfu/g), followed by common carp (6.81 log cfu/g), vacuu...

OBJECTIVES Bisphosphonates (BPN) have actions on a variety of cell types including: osteoclasts, osteoblasts, osteocytes, and endothelial cells. The objectives of this report are to review the current state of understanding of the effects of BPNs on orthodontic tooth movement and to provide evidence on BPN's in vivo effects on bone marrow-derived osteoprogenitor cells. MATERIAL AND METHODS Mi...

Recently, human multi-CSF was obtained by molecular cloning. In the present study, the effects of multi-CSF in vitro were investigated by comparative culture of whole bone marrow or progenitor cells obtained by sorting the cell fraction that binds the monoclonal antibody (MoAb) B13C5 (CD 34). Multi-CSF stimulated erythroid (BFU-E), multipotential (CFU-GEMM) and eosinophil (CFU-Eo) colonies in c...

CIonal assays for CFU-S, CFU-C, BFU-E, and CFU-E were employed to evaluate the effect of ouabain on the proliferation of mouse hematopoietic progenitor cells. Preincubation of bone marrow cells with ouabain at concentrations of 101_1012 M suppressed the proliferation of CFU-S as measured by the spleen colony assay. At lO9Mouabain, spleen colony formation was inhibited by more than 95%. When inc...

conclusion these data show that the identified gene encoded tet resistance gene as mfs–type multi-substrate efflux transporter, which contributes to intrinsic resistance on range of structurally unrelated compounds in salmonella species. background tetracyclines (tcs) are a type of broad-spectrum bacteriostatic antibiotics used for treatment of a wide variety of infections. these antibiotics ev...

we consider of the antimicrobial activity on the ag nanoparticles(ag nps) aqueous solutions, which was prepared using a stabilizer, such as poly(n vinyl 2 pyrrolidone pvp , for staphylococcus aureus) s aureus and escherichia coli e coli by measuring the minimum inhibitory concentration mic . antimicrobial effect of ag nps for s aureus and e coli was investigated using disk diffusion method also...
