Ischemia heart disease has become a ubiquitous cause of morbidity and a leading contributor to mortality worldwide. The present study was aimed to quantify the elemental levels for Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Pb, Sr, and Zn in the scalp hair and nails of myocardial infarction (MI) patients and counterpart controls by flame atomic absorption… (More)
Numerous epidemiological studies are preponderance of evidences intimating development of coronary artery disease caused by metal imbalance. The present study was aimed to analyze Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Pb, Sr, and Zn in the scalp hair of angina patients and healthy subjects/controls employing HNO3–HCLO4-based wet digestion followed by… (More)
In the title compound, C(15)H(16)N(2)O(5)S(2), the dihedral between the two aromatic rings is 81.33 (6)°. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further connected via N-H⋯O hydrogen bonds into a chain running along .
The title compound, C(12)H(10)BrN(3)O(3)S, crystallizes with two crystallographically independent mol-ecules in the asymmetric unit. The dihedral angles between the two six-membered rings in the mol-ecules are 34.1 (3) and 45.1 (2)°. In the crystal structure, mol-ecules are connected via N-H⋯O and N-H⋯N hydrogen bonding.
