Alterations of Sphingolipid Metabolism in Different Types of Polycystic Ovary Syndrome.

The roles of sphingolipids in polycystic ovary syndrome (PCOS) are still unknown. This study aimed to investigate the sphingolipid characteristics for different types of PCOS using liquid chromatography-mass spectrometry (LC-MS). A total of 107 women with PCOS and 37 healthy women as normal controls were studied.

Improved virtual gyroscope technology based on "current" probability density model.

Aiming at low precision of a micro-electromechanical systems (MEMS) gyroscope, the virtual gyroscope technology is used to fuse the data of several MEMS gyroscopes. In traditional virtual gyroscope technology, the angular acceleration of maneuver is modeled as white noise, which leads to low fusion accuracy in the dynamic state. So, the "current" probability density model is introduced to model the maneuvering angular rate accurately.

Chitinophaga salinisoli sp. nov., isolated from saline soil.

A novel aerobic bacterium, designated strain LAM9153, was isolated from a saline soil sample collected from Lingxian County, Shandong Province, China. Cells of strain LAM9153 were observed to be Gram-stain negative, non-motile, non-spore-forming and rod-shaped. The new isolate grew optimally at 30-35 °C, pH 7.

Arenimonas alkanexedens sp. nov., isolated from a frozen soil sample.

A novel facultatively anaerobic bacterium, designated strain LAM-WHM-D11, was isolated from a frozen soil sample of China. Cells of strain LAM-WHM-D11 were observed to be Gram-stain negative, non-motile and rod-shaped. Colonies were yellowish, and circular with convex shape.

Alicyclobacillus fodiniaquatilis sp. nov., isolated from acid mine water.

Two novel, Gram-stain-variable, moderately thermophilic, acidophilic, rod-shaped, endospore-forming bacteria, G45-16T and G45-17, were isolated from acid mine water of Zijin copper mine in Fujian Province, China. Phylogenetic analysis of 16S rRNA gene sequences showed that they were closely related to Alicyclobacillus acidoterrestris ATCC 49025T with sequence similarities of 96.8 %.

miR-146a G>C polymorphisms and risk of hepatocellular carcinoma in a Chinese population.

MicroRNAs (miRNAs) are thought to have a role in cancer development. We investigated the association among miR-146a G>C genetic variations, hepatitis B (HBV), and C (HCV) infection, and risk of hepatocellular carcinoma (HCC). Unconditional logistical regression analysis suggested that the miR-146a GG genotype and G allele carried a 2.

3-(1,3-Dithio-lan-2-yl-idene)-1-(4-meth-oxy-phen-yl)pyridine-2,4(1H,3H)-dione.

In the title compound, C(15)H(13)NO(3)S(2), the dithiol-ane ring adopts a twisted conformation. The mol-ecule exhibits a V-shaped conformation, with a dihedral angle of 79.05 (7)° between the benzene ring and the pyridine ring.
