Background/purpose: Growth arrest-specific 6 (Gas6) protein is involved in cell proliferation, differentiation, adhesion, migration in response to inflammatory processes. Human immunodeficiency virus (HIV) infection induces a chronic inflammatory condition and combination of antiretroviral therapy improves immune function and decreases the inflammatory state. The aim of this study was to assess the implications of Gas6 in chronic inflammation status of HIV-infected patients undergoing different third regimens of antiretroviral therapy.

This cross-sectional retrospective observational study aimed to characterize the prevalence and associated factors of low BMD in HIV patients.
Methods: Between 1 January 2015 and 31 December 2016, all patients aged 20 years or greater who sought for HIV care were included.
The heterobinuclear complex OsCl(PPh)[CHC(PPh)CFcO] (Fc = (CH)Fe(CH)) (1) in which the two metal centers were connected by the skeleton of the osmafuran and cyclopentadienyl was synthesized via a one-pot reaction of OsCl(PPh) and FcCOC[triple bond, length as m-dash]CH in high yield. Three derivatives (Os(η-OCOO)(PPh)[CHC(PPh)CFcO] (2), Os(NCS)(PPh)[CHC(PPh)CFcO] (3), and OsCl(dppb)[CHC(PPh)CFcO] (dppb = PhP(CH)PPh) (4)) were obtained by the ligand substitution reactions of complex 1 with different reagents (CsCO (2), NaSCN (3) and dppb (4)), respectively. All of these complexes were characterized by NMR spectroscopy and elemental analysis and the structures of complexes 1, 3 and 4 were further confirmed by single crystal X-ray diffraction.

To study RBSDV variation and recombination, we examined the segment 9 (S9) sequences of 49 RBSDV isolates from maize and rice in China. Three S9 recombinants were detected in Baoding, Jinan, and Jining, China.

In this study, molecular cloning, expression analysis of two different ghr genes (ghr1 and ghr2) in the tongue sole (Cynoglossus semilaevis) was conducted. As a result, the ghr1 and ghr2 cDNA sequences are 2364 bp and 3125 bp, each of which encodes a transmembrane protein of 633 and 561 amino acids (aa), respectively.

The results showed that Cu2+ and Zn2+ can accelerate Abeta40 aggregation, and both changed the morphology and size of Abeta40 aggregates. Zn2+ induced Abeta40 to form fibrous Abeta40 aggregates, while the amorphous and fibrous aggregates were produced by the interaction between Cu2+ and Abeta40.

In this study, the full length gh cDNA was cloned from C. semilaevis by homology cloning and the rapid amplification of cDNA ends polymerase chain reaction (RACE-PCR).

Insulin-like growth factor I (IGF-I) is a polypeptide hormone that regulates growth during all stages of development in vertebrates. To examine the mechanisms of the sexual growth dimorphism in the Tongue sole (Cynoglossus semilaevis), molecular cloning, expression analysis of IGF-I gene and IGF-I serum concentration analysis were performed. As a result, the IGF-I cDNA sequence is 911 bp, which contains an open reading frame (ORF) of 564 bp encoding a protein of 187 amino acids.

FC-1 is a cell membrane-penetrable chelator with a moderate chelation ability to Cu(2+) and Zn(2+) and can target metal-Aβ40 aggregates. Treatment with FC-1 led to enhanced cytotoxicity of the aggregates, because the aggregates were converted into a pool of oligomers.

Objective: To explore the feasibility of percutaneous vertebroplasty for the treatment of acute burst thoracolumbar fracture.
Methods: Fifty-eight patients (male 38 and female 20, ranging in age from 38 to 70 years, with an average of 56.8 years) with acute burst thoracolumbar fracture were treated by percutaneous vertebroplasty.
