Previous studies have shown that cerebral hypoxia results in increased activity of caspase-9 in the cytosolic fraction of the cerebral cortex of newborn piglets. The present study tests the hypothesis that hypoxia results in increased tyrosine phosphorylation of procaspase-9 and apoptotic protease activating factor-1 (Apaf-1) and the hypoxia-induced increased tyrosine phosphorylation of procasp...

This study aims to determine the prevalence of and variation in cognitive deficits in systemic lupus erythematosus (SLE) patients with a prior history of central nervous system involvement (+Hx CNS), and without (-Hx CNS); and the relationship of SLE-related cognitive deficits to medication dosage and disease activity. Ninety-four participants, 62 SLE and 32 controls, were screened for anxiety ...

BACKGROUND HX-1171 (1-O-hexyl-2,3,5-trimethylhydroquinone) is a promising antioxidant with therapeutic potential for hepatic fibrosis. The aim of this study was to investigate the tolerability and pharmacokinetics of HX-1171 in healthy volunteers. METHODS A randomized, single-blind, placebo-controlled, dose escalation study was conducted in 83 subjects. In the single ascending dose study, 20,...

Unprotected amide protons can undergo fast hydrogen exchange (HX) with protons from the solvent. Generally, NMR experiments using the out-and-back coherence transfer with amide proton detection are affected by fast HX and result in reduced signal intensity. When one of these experiments, (1)H-(15)N HSQC, is used to measure the (15)N transverse relaxation rate (R2), the measured R2 rate is convo...

Myelin formation and maintenance are crucial for the proper function of the CNS and are orchestrated by a plethora of factors including growth factors, extracellular matrix components, metalloproteases and protease inhibitors. Hemopexin (Hx) is a plasma protein with high heme binding affinity, which is also locally produced in the CNS by ependymal cells, neurons and glial cells. We have recentl...

In the Eplerenone Post-Acute Myocardial Infarction Heart Failure Efficacy and Survival Study (n=6632), eplerenone-associated reduction in all-cause mortality was significantly greater in those with a history of hypertension (Hx-HTN). There were 4007 patients with Hx-HTN (eplerenone: n=1983) and 2625 patients without Hx-HTN (eplerenone: n=1336). Propensity scores for eplerenone use, separately c...

Messenger RNA levels of rat organic anion transporter 1 (Oat1; Slc22a6) and Oat2 (Slc22a7) in kidney and Oat3 (Slc22a8) in liver are gender-predominant. Oat1 and Oat3 are male-predominant, whereas Oat2 is female-predominant. Gonadectomized and hypophysectomized (HX) rats were studied to determine whether sex steroids and/or growth hormone (GH) are responsible for these gender-divergent patterns...

"Small for size" syndrome is a major problem in hepatic surgery. The aim of this study is to investigate the effect of total splenectomy on liver regeneration following partial hepatectomy in rabbits. Animals were divided into two groups, 6 each: "Hx": hepatic resection and "Hx+Sp": hepatic resection and total splenectomy. Three days after skin closure, animals in the two groups were sacrificed...

We present BeppoSAX observations of the southern S1 region in the European Large-Area Infrared Space Observatory (ISO) Survey (ELAIS). These observations cover an area of D1.7 deg2 and reach an on-axis (D0.7 deg2) 2-10 keV (hard X-ray, or HX) sensitivity of D10~13 ergs s~1 cm~2. This is the Ðrst HX analysis of an ISOCAM survey. We detect nine sources with a signal-to-noise ratio four SNR HX [ 3...

A composite electrode was prepared by modifying glassy carbon microparticles with gold nanoparticles (Au-nps) and xanthine oxidase enzyme (XOD) for xanthine (X) and hypoxanthine (Hx) detection. After the optimization of the system for X, the biosensor was characterized for X and Hx. A linearity was obtained in the concentration range between 5.00 x 10(-7) and 1.00 x 10(-5) M for X with equation...
