Background: Previous studies have shown that type 2 diabetes mellitus (T2DM) can cause sarcopenia; however, these conditions may have a bidirectional association. This study aimed to explore the longitudinal association between possible sarcopenia and new-onset T2DM.

Methods: We conducted a population-based cohort study using nationally representative data from the China Health and Retirement Longitudinal Study (CHARLS).

The study aimed to explore the associations of rs4988300 and rs634008 in the low-density lipoprotein receptor-related protein 5 () gene with bone mineral density (BMD), bone turnover markers (BTM), and fractures in elderly patients with osteoporosis (OP). Our study included 328 unrelated OP patients with or without fractures. Genomic DNA was extracted for genotyping.

An aerobic, Gram-stain negative, rod-shaped and non-motile strain, BJC16-A31, was isolated from the wetland soil sample taken from Daxing'anling, Heilongjiang, People's Republic of China. Strain BJC16-A31 was found to be oxidase- and catalase-positive, and produced light orange colonies on modified R2A agar. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain BJC16-A31 is closely related to Mucilaginibacter gotjawali SA3-7 with 96.

BACKGROUND Adrenergic receptor α2A (α2A-AR) is up-regulated in osteoporotic bone osteoblasts. Previous research demonstrated an association between polymorphism of a2A-AR gene and bone mineral density (BMD) as well as bone turnover markers (BTMs) in the Slovenian population. The present study aimed to investigate the association of rs1800544 polymorphism of α2A-AR gene with BMD and BTMs in the Chinese elderly population with osteoporosis (OP) or with osteoporotic fractures.

A catalytic enantioselective Mukaiyama-Mannich reaction of cyclic C-acylimines with difluoroenoxysilanes is reported. (S)-TRIP enables the enantioselective synthesis of a series of novel difluoroalkylated indolin-3-ones bearing a quaternary stereocenter in up to 97% yield and 98% ee. The synthetic utility of this protocol is highlighted by efficient conversion of the products to the corresponding indolin-3-one derivatives without any erosion of the enantiopurity.

Objective: To compare the efficacy differences between acupoint catgut-embedding combined western medicine (ACCWM) and simple western medicine (WM) for treatment of epilepsy of generalized seizures type.

Methods: Fifty-two patients with epilepsy of generalized seizures type were randomly divided into an ACCWM group (n=30) and a WM group (n=22). Dazhui (GV 14), Yaoshu (GV 2), Jiuwei (CV 15), Qihai (CV 6) were selected in the ACCWM group as the main acupoints combined with routine antiepileptic drugs, Valpromide was taken orally, 2.

A general method for the one-pot, three-component Strecker reaction of ketones was developed using Brønsted acids as organocatalysts. A series of alpha-aminonitriles were obtained in good to excellent yields (79-99%). A preliminary extension to a catalytic enantioselective three-component Strecker reaction of ketones (up to 40% ee) is also described.
