introduction: transforming growth factor-beta 1 (tgf-β1) is a pleiotropic cytokine with potent anti-inflammatory property, which has been considered as an essential risk factor in the inflammatory process of ischemic stroke (is), by involving in the pathophysiological progression of hypertension, atherosclerosis, and lipid metabolisms. -509c/t tgf-β1 gene polymorphism has been found to be assoc...

In this paper, the dynamic behavior of a lightweight 5-axis milling concept is analyzed using finite element simulation. It has a pose-dependent dynamic behavior with structural Eigen modes between 28 Hz and 50 Hz. Based on these results, the stability lobe diagrams (SLD) for the milling module at different axis-positions are derived. The milling module shows a changing process stability with a...

Micromilling process is used for fabrication and manufacturing of miniaturized components. Very high spindle rotational speeds are required in micromilling to reduce the chip load and to counter the low flexural rigidity of the micro-tool while machining hard materials. Apart from the high rotational speed (>100,000 rpm) which can excite dynamic instability, the dynamic force variation in micro...

We summarize some of the most frequenthly used rodent animal models of temporal lobe epileps and the impact of chemoconvulsants on them. Temporal lobe epilepsy is the most common epilepsy in humans in which seizures spread to the neighboring cortiase and hippocampal neuron loss and other neuropathological take place. Temporal lobe epilepsy and the other form of epilepsy cannot acquired in chini...

the wisconsin test card sorting test (wcst) is a neuropsychological test that has been suggested as a more specific test for frontal lobes dysfunctions. this study was designed to determine whether wcst is able to differentiate between iranian psychiatric patients with cognitive disorders and normal subjects, and whether wcst scores are related to severity of symptoms in depressive and schizoph...

In response to brief glutamate exposure, NMDA receptors produce excitatory currents that have sub-maximal amplitudes and characteristically slow kinetics. The activation sequence starts when glutamate binds to residues located on the upper lobe of extracellularly located ligand-binding domains (LBDs) and then contacts lower lobe residues to bridge the cleft between the two hinged lobes. This ev...

The ramifications of the portal vein in the liver of horses were studied by using corrosion casting and gross dissection. The portal vein in the horse supplies the hepatic lobes by six major branches. The right lobe is supplied by three main branches, namely the dorsal diaphragmatic, the right caudodorsal and the right intermediate branches. The left branch supplies the left lateral and medial ...
