crude glycerol (cg) is an abundantly available and cheap by-product from biodiesel production. value-added applications for cg are highly wanted by industry and several processes such as the use of cg for enhanced oil recovery have been proposed. the aim of this study was to evaluate the sulfide production of sulfate-reducing bacteria (srb) indigenous to oil reservoirs using cg as substrate. th...

bilberry [vaccinium myrtillus linn. (ericaceae)] fruit (vmf) has been traditionally used for treatment of bladder stones, biliary disorders, scurvy, coughs, and lung tuberculosis. vmf may have some pharmaceutical properties owing to these uses, but in vivo and in vitro studies are limited for clarification of medicinal activity and its antidiabetic and antioxidant properties are not investigate...

the effect of physiological concentrations of caffeine (purified from persian tea) on adenosine deaminase (ada) activity at physiological and pathological concentrations of adenosine (as substrate) in 50 mm tris-hcl buffer (ph 7.3) at 37°c was investigated, using uv-vis spectroscopy. ada exhibited a bi-phasic activity behavior and both phases showed positive cooperativities indicating adenosine...

interaction between urokinase-type plasminogen activator (upa) and its receptor (upar) plays an important role in the progression of numerous cancer types including breast cancer by promoting tumor initiating,  proliferation,  invasion  and  metastasis.  hence,  disruption  of  this  interaction  inhibits  their downstream cascades and subsequently tumor growth. for this, we created two series ...

The nano sized copper oxide material (CuONPs) were prepared by the greener way and an approach functionalized polymer using Sarcostemma acidum stem extracts. in-vitro anti-diabetic activity was studied through α-glucosidase α-amylase inhibitory methods demonstrated in stem, biological synthesized CuONPs polymerized CuONPs. percentage inhibition at 100 μg/ml, 200 300 400 μg/ml 500μg/ml concentra...

To examine the cross-talk between NK cells and DCs in hepatitis C virus (HCV) infection, we isolated monocytes from 20 chronic HCV patients healthy controls. Monocytes were used to generate immature which pulsed with peptides (core, NS3–NS4, NS5). Four different cocultures carried out: E1, both a patient; E2, control cocultured E3, patient control; E4, control. Using flow cytometry, assessed ef...

Lichens are symbiotic organisms that composed of fungal partners and photosynthetic algal partners. During the process in lichen thallus, fungus synthesizes certain secondary metabolites which lecanoric acid is very important terms antibiotic properties. Considering vital importance acid, present study aimed to produce from thallus Parmotrema austrosinense using Modified Bold’s basal salt mediu...

Cyanobacterial blooms in eutrophic waters pose serious threats to public health, water quality, and ecological management worldwide. Mitigation of the problem is essential maintain stainable development. In this study, effectiveness local soils collected from Tri An Reservoir (TAR) lakeside removal cyanobacteria Microcystis aeruginosa was investigated. The organic matter content clay mineral we...

Within neurons, mitochondria are nonuniformly distributed and are retained at sites of high activity and metabolic demand. Glutamate transport and the concomitant activation of the Na(+)/K(+)-ATPase represent a substantial energetic demand on astrocytes. We hypothesized that mitochondrial mobility within astrocytic processes might be regulated by neuronal activity and glutamate transport. We im...
