the herpes simplex virus type 1 (hsv-1) tegument protein, vp22 has been reported to have the property of intercellular transport. the previous studies have shown that following expression of a fusion protein containing vp22 it spreads to every cell in a monolayer and concentrates in the nucleus. in spite of these reports, some studies have shown that vp22 trafficking and its nucleus accumulatio...
background brucellosis is an important cosmopolitan infection disease caused by organisms belonging to the genus brucella. the cgt gene (cyclic β-1, 2 glucan transporter gene) is a virulent factor in brucella genus. the present study was conducted with the aim of cloning and expression of brucella cgt gene. materials and methods brucella melitensis cgt gene was amplified from extracted chromoso...
Thiazides have been used in patients with nephrogenic diabetes insipidus (NDI) to decrease urine volume, but the mechanism by which it produces paradoxic antidiuretic effect remains unclear. Previous studies reported that downregulation of aquaporin-2 (AQP2) is important for development lithium-induced (Li-induced) polyuria and hydrochlorothiazide (HCTZ) increases renal papillary osmolality Na<...
Maintenance of optimal lopinavir (LPV) concentration is essential for effective antiretroviral therapy and prevention of mother-to-child transmission of human immunodeficiency virus. However, little is known about the effects of inflammation on the pharmacokinetics of this protease inhibitor and drug transporter substrate, particularly during gestation. Our objective was to study the effect of ...
Cervical nerve root injury commonly leads to radicular pain. Normal sensation relies on regulation of extracellular glutamate in the spinal cord by glutamate transporters. The goal of this study was to define the temporal response of spinal glutamate transporters (glial glutamate transporter 1 [GLT-1], glutamate-aspartate transporter [GLAST], and excitatory amino acid carrier 1) following nerve...
Perivascular adipose tissue (PVAT) reduces vasoconstriction to norepinephrine (NE). A mechanism by which PVAT could function to reduce vascular contraction is by decreasing the amount of NE to which the vessel is exposed. PVATs from male Sprague-Dawley rats were used to test the hypothesis that PVAT has a NE uptake mechanism. NE was detected by HPLC in mesenteric PVAT and isolated adipocytes. U...
In our study, ampicillin (AMP)-mediated decrease of enterobacteria caused increases in hepatic bile acid concentration through (at least in part) elevation of bile acid synthesis in C57BL/6N mice. We investigated the involvement of enterobacteria on intestinal bile acid absorption in AMP-treated mice in the present study. Fecal enterobacterial levels and fecal bile acid excretion rates were mar...
in addition to increment of the vehicle sprung mass, the main physical effects of addition of cng tank to the vehicle are the longitudinal and height displacement of center of gravity, which have the most influences on the handling, braking, roll stability and spin stability of the vehicle. increment of cng tank mass to the sprung mass of the vehicle increases the vehicle under-steer gradient, ...
We have recently shown that upregulation of glutamate transporter 1 (GLT1) in the brain is associated in part with reduction in ethanol intake in alcohol-preferring (P) male rats. In this study, we investigated the effects of a synthetic compound, (R)-(-)-5-methyl-1-nicotinoyl-2-pyrazoline (MS-153), known to activate GLT1 on ethanol consumption as well as GLT1 expression and certain signaling p...
Glutathione (GSH) is an important cellular constituent for normal liver homeostasis. Certain drug-metabolizing enzyme inducers (i.e., phenobarbital [PB] and pregnenolone-16alpha-carbonitrile [PCN]) increase biliary excretion of GSH-derived sulfhydryls (SH) as well as bile flow, whereas other drug-metabolizing enzyme inducers (i.e., 3-methylcholanthrene [3MC] and benzo(a)pyrene [BaP]), do not. T...
