some wastes especially wastes of food industries need to be treated in order to recover some value-added products. one of these valuable products is biological pesticides. today, the most successful biological pesticides are produced by gram-positive, rod-shape bacteria, the genus bacillus that produces crystalline endotoxin proteins during spore formation. these toxins will be activated when t...

The life span of intestinal epithelial cells (IECs) is short (3-5 days), and its regulation is thought to be important for homeostasis of the intestinal epithelium. We have now investigated the role of commensal bacteria in regulation of IEC turnover in the small intestine. The proliferative activity of IECs in intestinal crypts as well as the migration of these cells along the crypt-villus axi...

in order to investigate the effects of cattle manure, benefit fungi of trichoderma species and psudomunas spp. bacteria on seedling emergence parameters, growth and yield of wheat (triticum aestivum l.) a pot experiment was carried out in factorial (23) arrangement based on a randomized complete design with three replications. the treatments were three levels of cattle manure (10, 20 and 30 t.h...

The aim of our work was to compare cytotoxic and membrane-damaging effects of O. majorana L. essential oil and linalool on Hep G2 and to investigate their possible protective (antioxidant) effects against H2O2 induced membrane damage. The oils were investigated by GC and GC-MS and antioxidant activity was evaluated by DPPH and -carotene–linoleic acid assays. Assessment of cell viability was ma...

OBJECTIVE We investigated the prevalence of suicidal ideation in relationship with symptoms of sleep disruption in people with postural orthostatic tachycardia syndrome (POTS). METHODS Online surveys (including the Pittsburgh Sleep Quality Index and the Suicide Behaviors Questionnaire - Revised) were completed by 705 POTS patients and 170 non-POTS controls. RESULTS Poor sleep quality was re...

background: free radical formation and oxidative stress might play an important role in the pathogenesis of parkinson's disease (pd). in vitro data indicate that neuromelanin (nm) pigment is formed the excess cytosolic catecholamine that is not accumulated into synaptic vesicles via the vesicular monoamine transporter 2 (vmat2). we designed this study to investigate the neuroprotective eff...

Soil microorganisms, in particular so-called plant growth promoting rhizobacteria (PGPR), can positively affect plants, stimulating by changing their metabolism. In addition, these bacteria synthesize hormone-like chemicals that influence the formation of primary roots. This work was aimed to determine possibility using sterile cell-free cultural medium obtained after endophytic Priestia endoph...
