background: mesenchymal stem cells (mscs) can be expanded and differentiated into many mature cell types including smooth muscle cells (smcs). in addition to growth factor, cyclic stretch contributes to differentiation of stem cells. mechanical stimuli are critical to morphological changes, development, regeneration, differentiation and pathology of mesenchymal tissues. the aim of this study is...

Using immunohistochemistry at the conventional light, confocal and electron microscopic levels, we have demonstrated that rat stomach ECL cells store histamine and pancreastatin in granules and secretory vesicles, while histidine decarboxylase occurs in the cytosol. Furthermore the ECL cells display immunoreactivity for vesicular monoamine transporter type 2 (VMAT-2), synaptophysin, synaptotagm...

Background: Bacillus cereus is a spore-forming food-borne pathogen often associated with food products such as meat, vegetables, soup, rice, and milk and other dairy products. 1 - 20 % of total outbreaks of food intoxication in the world are caused by Bacillus cereus. There is an increasing interest in the use of plant-derived antimicrobial compounds as natural preservatives for foods. Such as ...

An 87-year-old man who had been under urological follow-up with a raised prostate-specific antigen was referred to haematology widespread infiltrative bone disease, sternal and vertebral fractures normocytic anaemia. He two-year history of pain, which worsened in the previous two months. Serum protein electrophoresis revealed an immunoglobulin (Ig) A lambda paraprotein at too low concentration ...

objective: mesenchymal stem cells (mscs) can differentiate into various cell types. since cysteine has structural similarities to neuronal inducers β-mercaptoethanol and glutathione, we examined its effect on neural induction of rat bone marrow mscs. materials and methods: in this experimental study, cells were treated in a medium containing 1mm cysteine for 24 hours prior to treatment with neu...

in this work, we report the effect of biopolymers (starch and gelatin) on in vitro biocompatibility property of nano hydroxyapatite (nhap) composites. cell culture and mtt assays were performed for in vitro biocompatibility. they show that nhap can affect the proliferation of cells and the nhap-starch and nhap-gelatin biocomposites have no negative effect on the cell morphology, viability and p...
