A dinuclear zinc complex [Zn2L2] (1), and four mononuclear complexes [ZnBr2(LH)2] (2), [ZnCl2(LH)2] (3), [Zn(LH)2(NCS)2] (4) [ZnI(CH3OH)L] (5), have been prepared from the Schiff base 5-bromo-2-((cyclohexylimino) methyl)phenol (HL) by microwave irradiation method. All were characterized CHN elemental analyses, infrared electronic spectra. Structures of further studied single crystal X-ray deter...

A protein kinase has been purified from the bovine corpus luteum by acid precipitation, ammonium sulfate fractionation and chromatography on DEAE-cellulose and hydroxylapatite columns. The enzyme has a molecular weight of approximately 159,000. DEAE-cellulose chromatography resolved the protein kinase activity into two peaks, designated as KI and KII. Both peaks possessed adenosine 3’,5’-monoph...

Immunization of adult male rabbits with a synthetic luteinizing hormone-receptor peptide (LH-RP; representing amino-acids 21-41 of the extracellular domain of the rat LH receptor) resulted in production of high-titer antibodies capable of interacting with particulate and cell-based LH receptors. The antibody produced was able to inhibit binding of 125I-labeled human chorionic gonadotropin (hCG)...

Horse LH/chorionic gonadotrophin (eLH/CG) exhibits, in addition to its normal LH activity, a high FSH activity in all other species tested. Donkey LH/CG (dkLH/CG) also exhibits FSH activity in other species, but about ten times less than the horse hormone. In order to understand the molecular basis of these dual gonadotrophic activities of eLH/CG and dkLH/CG better, we expressed, in COS-7 cells...

It has been reported that luteinizing hormone (LH) had thyropropic effect on rat and human thyroid membrane. It has been known that patients with PCOS have elevated LH levels in comparison to healthy controls.The goiter prevalence is more common in women than in men regardless of population. The higher incidence of thyroid diseases in women has been previously attributed to higher estradiol lev...

Life History (LH) theory describes the existence of individual differences in the optimal allocation of inherently limited bioenergetic and material resources towards different types of reproductive-enhancing activities. LH theory predicts that slow LH (‘‘High-K”) individuals are biased toward allocating resources toward enhancing the phenotypic quality (e.g., physical and mental health) of one...
