2-Hydroxyglutarate (2-HG) was enantiomerically separated using copper(II) acetate and N,N-dimethyl-L-phenylalanine as chiral additives. These compounds formed diastereomeric complexes with 2-HG, which were successfully on an achiral (ODS) column. Several parameters, such additive concentration, the type of organic modifier, column temperature, optimized. Using optimal mobile phase (1 mM 2 in a ...
High-resolution organic carbon isotope ( ? 13 C), Hg concentration and isotopes curves are presented for the Permian-Triassic boundary (PTB) sections at Guryul Ravine (India) Meishan D (China). The total (TOC)-normalized concentrations reveal more intense environmental changes Latest Permian Mass Extinction (LPME) earliest Triassic (ETME) horizons coinciding with major C shifts. To highlight pa...
The title compound, [Hg2(C11H16O2PS2)4], is a dinuclear complex with a distorted tetra-hedral geometry around each Hg(II) atom. Although the two Hg(II) atoms are surrounded by the same ligand, two different coordination modes are observed: one is chelating and the other bridging. The Hg-S bonds form two distinct pairs of long and short bonds. One pair includes both chelating and bridging Hg-S b...
Activation of the intrarenal renin‑angiotensin system (RAS), which has been identified in podocytes and mesangial cells, is a novel mechanism in the progression of diabetic kidney disease (DKD). The present study aimed to identify the local RAS in glomerular endothelial cells (GEnCs). Rat GEnCs were stimulated by culture medium containing 30 mmol/l glucose for 12, 24, 48 and 72 h. Angiotensin I...
MerR, the metalloregulator of the bacterial mercury resistance (mer) operon, binds Hg(II) with high affinity. To study the mechanism of metal-induced activation, a small protein was previously engineered embodying in a single polypeptide the metal-binding domain (MBD) ordinarily formed between two monomers of MerR. Here the physiological and biochemical properties of MBD expressed on the cell s...
OBJECTIVE We aimed to determine upright heart rate and blood pressure (BP) changes to suggest diagnostic criteria for postural orthostatic tachycardia syndrome (POTS) and orthostatic hypertension (OHT) in Chinese children. METHODS In this cross-sectional study, 1449 children and adolescents aged 6-18 years were randomly recruited from two cities in China, Kaifeng in Henan province and Anguo i...
The simple Hg(II)-detection system was studied and developed using dithizone nanofiber loaded membrane. Dithizone is one of the most frequently used chemical substances for Hg(II) ions extraction in water. Hg(II)-dithizone complex substance [Hg(HDith)2] is stable in acidic condition and, presenting with the orange-brown color. To prepare dithizone nanoloaded membrane, dithizone solution (in ace...
In the title complex, [HgBr(2)(C(12)H(11)NO(3))], the Hg(II) ion has a distorted core trigonal-planar geometry comprising two Br atoms and one quinoline N atom of the methyl 2-(quinolin-8-yl-oxy)acetic acid ligand. The angles around the Hg atom vary from 100.31 (15) to 152.65 (4)°. Two additional Hg⋯O inter-actions [2.739 (1) and 2.905 (1) Å] complete the coordination sphere about the Hg(II) atom.
