The cholesterol side chain cleavage enzyme (CYP11A1) gene plays an important part in the synthesis of sex hormones and has been reported to be involved in the pathogenesis of polycystic ovary syndrome. A case–control study including 314 PCOS patients and 314 controls was conducted to assess the association of the SNPs rs4077582 and rs11632698 in CYP11A1(More)
Magnetic cellulose nanocrystals (MCNCs) were prepared and used as an enzyme support for immobilization of Pseudomonas cepacialipase (PCL). PCL was successfully immobilized onto MCNCs (PCL@MCNC) by a precipitation-cross-linking method. The resulting PCL@MCNC with a nanoscale size had high enzyme loading (82.2 mg enzyme/g) and activity recovery (95.9%).(More)
The efficient anti-Prelog asymmetric reduction of 2-octanone with Acetobacter pasteurianus GIM1.158 cells was successfully performed in a biphasic system consisting of deep eutectic solvent (DES) and water-immiscible ionic liquid (IL). Various DESs exerted different effects on the synthesis of (R)-2-octanol. Choline chloride/ethylene glycol (ChCl/EG)(More)
BACKGROUND This research investigated the response of vascular active factors, vascular endothelial growth factor (VEGF) and angiotensin-II (AT-II) to ovarian stimulation during 24 hours in patients with polycystic ovary syndrome (PCOS). MATERIALS AND METHODS In this clinical trial study, 52 patients with PCOS and 8 control cases were stimulated with(More)
