Using a sample of 96,201 primary red clump (RC) stars selected from the LAMOST and Gaia surveys, we investigate stellar structure Galactic disk. The show two separated sequences high-[{\alpha}/Fe] low-[{\alpha}/Fe] in [{\alpha}/Fe]-[Fe/H] plane. We divide into five mono-abundance populations (MAPs) with different ranges [{\alpha}/Fe] [Fe/H], named as high-[{\alpha}/Fe], & high-[Fe/H], low-[Fe/H...

Enhanced pro-inflammatory cytokine production is considered a pathogenic factor in non-alcoholic fatty liver disease (NAFLD). Peripheral blood production of interleukin-1alpha (IL-1alpha) and tumor necrosis factor-alpha (TNF-alpha) was studied in relation to the severity of histological changes of the liver in obese NAFLD patients. Basal levels in serum and production of IL-1alpha and TNF-alpha...

OBJECTIVES The role of p38 mitogen-activated protein kinase (MAPK) activation in lipopolysaccharide (LPS)-induced myocardial dysfunction has not been clearly defined. Our aim was to investigate the contribution of p38 MAPK in myocardial tumor necrosis factor-alpha (TNF-alpha) expression, cardiac function and survival during acute endotoxemia in mice. METHODS Acute endotoxemia was induced by L...

Two deacetyl-thymosin alpha(1) analogues containing Phe (4Br) or D-Phe (4Br) residue-[D-Phe(4Br)(21)]deacetyl-thymosin alpha(1) and [Phe(4Br)(21)]deacetyl-thymosin alpha(1), respectively-were synthesized by the manual solid-phase method and their immunological effects on the low E-rosette-forming lymphocytes of uraemic patients were examined. One of the synthetic analogues, [Phe(4Br)(21)deacety...

The interaction of alpha-thrombin with the hirudin (HV1) fragment N alpha-acetyl desulfo hirudin45-65 (P51) was investigated. Kinetic analysis revealed that P51 inhibits the proteolysis of a tripeptidyl substrate with Ki = 0.72 +/- 0.13 and 0.11 +/- 0.03 microM for bovine and human alpha-thrombins, respectively. The inhibition was partially competitive, affecting substrate binding to the enzyme...

OBJECTIVE This study aimed to establish reference ranges of serum concentrations of copper, zinc, retinol, alpha-tocopherol, copper:caeruloplasmin and copper:zinc ratios in a group of healthy Omani men and women. MATERIALS AND METHODS Assay techniques employed were atomic absorption spectrophotometry (copper and zinc), reverse-phase high-pressure liquid chromatography with isocratic elution (...

Alpha-interferon (alpha-IFN) and gamma-interferon (gamma-IFN) are highly effective biologic agents in the treatment of chronic myelogenous leukemia (CML). 4-hydroperoxycyclophosphamide (4-HC) is the most commonly used chemotherapeutic drug when purging bone marrow contaminated with malignant cells. To investigate the efficacy of alpha-IFN, gamma-IFN and 4-HC as purging agents in CML patients, K...

The two major metabolites of (+/-)3,4-methylenedioxyamphetamine (MDA), alpha-methyldopamine (alpha-MeDA) and 3-O-methyl-alpha-methyldopamine (3-O-Me-alpha-MeDA), were administered to rats intracerebroventricularly and into brain parenchyma. In addition, their precursors, (alpha-MeDOPA and 3-O-Me-alpha-MeDOPA, respectively) were administered systemically, individually and in combination. None of...
