to determine the importance of q 10 h 2 as an antioxidant in cancer, we measured the activity of lipoamide dehydrogenase (q 10 h 2 recycling enzyme) in hl-60 and normal lymphocyte. the cultured cells of hl-60 and human normal lymphocytes were assayed in cell lysate of given number of both hl-60 and normal lymphocyte. the activity of lipoamide dehydrogenase and the protein concentration were det...

L-Arginine (Arg or R) is a non-toxigenic, metabolically versatile and conditionally essential amino acid. Single-pot synthesis of Arg modified magnetic nanoparticles (RMNPs) was achieved using magnetite nanoparticles (MNPs) and binary function of Arg as a functional group and an alkali precipitator. This modification is supposed to offer several advantages to the MNPs from a bio-application vie...

  To detect the effects of sympathomimetic drugs with selective action on β1 and β2 adrenoceptors, male albino mice were treated by intraperitoneal administration of dobutamine and terbutaline for 15 days. Three groups of mice were selected as dobutamine, terbutaline and control groups, respectively. At the end of the experiment, the animals were sacrificed and the parotid glands were removed a...

silver nano-particles have different biological applications due to their compatibility. chemical methodsusually result in remaining some amounts of toxic reactions on the nano-particles. for this reason, the useof plants as sustainable and accessible resources in preparation of compatible nano-particles has attracteda lot of attention in the recent years. this research investigated the green s...

This study was aimed to evaluate the correlation between in vitro fermentation and in situ degradation parameters and to predict dry matter degradability and energy protein synchronization of roughage based diets. Different inclusion of roughage in diets [roughage 50% diet (R50D), roughage 60% diet (R60D), roughage 65% diet (R65D) and roughage ...

When an experience is encrypted into a long-lasting memory, it is believed that specific sets of neurons in the brain of the animal undergo changes including the strengthening of preexisting synapses and the growth and maintenance of new synaptic connections. These activity-dependent synaptic changes appear to require the coordination of a variety of cellular processes in spatially separated ce...

INTRODUCTION The regulation of protein synthesis is an important part of the regulation of gene expression. Regulation of mRNA translation controls the levels of particular proteins that are synthesized upon demand, such as synthesis of the different chains of globin in hemoglobin, or the production of insulin from stored insulin mRNAs in response to blood glucose levels, to name a few. The con...

diphtheria is a fatal disease caused by exotoxin of corynebacterium     diphtheria .  this toxin consists of   two chains, catalytic chain (a) and binding (b) chain. by binding chain (b),   the toxin binds to its receptor on numerous body cells such as myocardial,   kidney and peripheral nerve cells. after entering, catalytic chain (a)   inhibits protein synthesis and finally can cause cell dea...
