melatonin regulates some major physiological processes such as maturation and function of reproductive system, pubertal development, seasonal reproduction and adaptation. the activation of melatonin hormone is mediated by melatonin receptor. previous studies showed melatonin receptor 1a gene (mtnr1a) is highly polymorphic in seasonally breeding species. the aim of the present study was detectio...
Introduction & Objective: One candidate gene for colorectal cancer susceptibility is exonuclease1 (EXO1) .It is a member of RAD2 nuclease family. It plays a main role in mismatch repair. EXO1 acts also in DNA replication and recombination. Single nucleotide polymorphisms (SNPs) are shown to be related with cancer incidence. The aim of the present study was to examine the association between P...
Mononuclear MnII oxidation catalysts with aminopyridine-based ligands achieve high turnover-number (TON) enantioselective epoxidation of alkenes H2O2. Structure reactivity relations indicate a dependence enantioselectivity and maximum TON on the electronic effect peripheral ligand substituents. Competing H2O2 disproportionation is reduced by carrying out reactions at low temperatures slow addit...
Decomposition of transition-metal amidinates [M{MeC(NiPr)2} n ] [M(AMD) n ; M=MnII, FeII, CoII, NiII, n=2; CuI, n=1) induced by microwave heating in the ionic liquids (ILs) 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIm][BF4]), 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIm][PF6]), 1-butyl-3-methylimidazolium trifluoromethanesulfonate (triflate) ([BMIm][TfO]), and 1-butyl-3-methyl...
We present the results of a spectroscopic analysis extremely strong damped Lyman-{\alpha} absorbers (ESDLAs, log N(Hi)>=21.7) observed with VLT-XShooter. ESDLAs probe gas from within star-forming disk associated galaxies and thus provide unique opportunity to study interstellar medium at high-redshift. report column densities (N), equivalent widths (w), kinematic spread ({\Delta} v90) species n...
In a previous paper some of us presented the structure and properties new family ionic liquids, ILs, with common cation, 1-butyl-3-methyl imidazolium (the popular [C4C1Im]+ or [BMIM]+) variety anions based in thiocyanate (SCN)−: one reference sample ten anionic metal complexes different valences: AlIII, MnII, FeIII, CrIII, NiII, HgII, ZnII, CoII CuI, resulting, respectively, [BMIM](SCN), [BMIM]...
