Correlation between Calpain-10 single-nucleotide polymorphisms and obstructive sleep apnea/hypopnoea syndrome with ischemic stroke in a Chinese population: A population-based study.

Background: Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a common chronic disorder which is followed by various complications. Calpain-10 belongs to a commonly expressed member of the Calpain-like cysteine protease family, which acts as risk marker for some diseases. The purpose of this study is to elucidate correlation between Calpain-10 single-nucleotide polymorphisms (SNPs) and the incidence of OSAHS followed by ischemic stroke (IS).

In the title compound, [Ni(CHO(2))(2)(C(18)H(12)N(6))(H(2)O)(2)](n), the Ni(II) ion, lying on a crystallographic inversion center, has a distorted octa-hedral coordination comprising two water ligands, two O-atom donors from formate ligands and two N-atom donors from the 2,4,6-tris-(4-pyrid-yl)-1,3,5-triazine ligands. These ligands bridge the Ni(II) complex units, forming zigzag chains along the c axis. Adjacent chains are linked by O-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network.

In the title compound, {[Cu(C(18)H(12)N(6))]NO(3)·H(2)O}(n), the Cu(I) ion is coordinated by three N atoms [Cu-N 1.962 (3)-2.019 (3) Å] from three 2,4,6-tri-4-pyridyl-1,3,5-triazine (L) ligands.
