Evaluation of the Bioequivalence of Acarbose in Healthy Chinese People.

The purpose of this study was to determine whether the reference formulation and test formulation of acarbose are bioequivalent among healthy Chinese subjects based on evaluation of the pharmacodynamic end point. Two clinical trials with acarbose were conducted: study A, a pilot study (n = 12; 50 and 100 mg), and study B, a pivotal study (n = 60; 50 mg). In study A, there was a dose-dependent relationship between 50 mg acarbose and 100 mg acarbose and a significant difference compared with sucrose alone.

Then, the primary rat hepatocytes model was established to explore the effects of Danshensu on the uptake of rosuvastatin by hepatocytes.

Emergence of human-like H3N2 influenza viruses in pet dogs in Guangxi, China.

Background: After the 1968 H3N2 pandemic emerged in humans, H3N2 influenza viruses continuously circulated and evolved in nature. An H3N2 variant was circulating in humans in the 1990s and subsequently introduced into the pig population in the 2000s. This virus gradually became the main subtype of swine influenza virus worldwide.

Ginsenoside Rb1 reduces fatty liver by activating AMP-activated protein kinase in obese rats.

Ginsenoside Rb1 (Rb1), a natural compound extracted from ginseng, exerts anti-obesity activity and improves insulin sensitivity in high-fat diet (HFD)-induced obese rats. The objective of the current study was to evaluate the protective effect of Rb1 on fatty liver in HFD-induced obese rats and to elucidate underlying mechanisms. After chronic intraperitoneal administration, Rb1 (10 mg/kg) significantly ameliorated hepatic fat accumulation in HFD-induced obese rats, as demonstrated by reduced liver weight, hepatic triglyceride content, and histological evaluation of liver sections by hematoxylin and eosin and Oil Red O staining.

[Research progress of the atypical kinetic profiles of cytochrome P450 enzymes].

Cytochrome P450 enzymes are composed of many isozymes and involved in the biotransformation of both exogenous and endogenous substances. A growing number of studies have found that the P450 enzymes do not always follow the classical Michaelis-Menten kinetics, but show atypical kinetic behavior, which is also the current research hotspot. In this paper, the category and mechanisms of atypical kinetics of the P450 enzyme were reviewed, providing theoretical basis for the research of enzyme kinetics.

[Effect of OATP1B1 521T --> C heterogenesis on pharmacokinetic characterstics of rosuvastatin in Chinese volunteers].

This study is to report the effect of OATP1B1 gene mutation in the 521T --> C in Chinese human on the pharmacokinetics of rosuvastatin and guide the reasonable clinical application of rosuvastatin by the feature of genetic polymorphism of OATP1B1. Plasma samples were determined with LC-MS: the analyte and internal standard pitavastatin were both analyzed by MS in the ESI, m/z was 480.0 for rosuvastatin and 420.

Can azulene-like molecules function as substitution-free molecular rectifiers?

The feasibility of employing azulene-like molecules as a new type of high performance substitution-free molecular rectifier has been explored using NEGF-DFT calculation. The electronic transport behaviors of metal-molecule-metal junctions consisting of various azulene-like dithiol molecules are investigated, which reveals that the azulene-like molecules exhibit high conductance and bias-dependent rectification effects. Among all the substitution-free azulene-like structures, cyclohepta[b]cyclopenta[g]naphthalene exhibits the highest rectification ratio, revealing that the all fused aromatic ring structure and an appropriate separation between the pentagon and heptagon rings are essential for achieving both high conductance and high rectification ratio.

The effect of herbal medicine danshensu and ursolic acid on pharmacokinetics of rosuvastatin in rats.

The aim of this study was to explore potential herb-drug interaction between danshensu or ursolic acid and rosuvastatin. Compared to the control group given rosuvastatin alone, the concurrent use of danshensu (46 mg/kg) or ursolic acid (80 mg/kg) prior to the oral administration of rosuvastatin (100 mg/kg) increased the systemic exposure of rosuvastatin more than twofold. The plasma clearance of rosuvastatin was reduced to more than 57% in the presence of danshensu or ursolic acid.

Evidence for an ancient whole-genome duplication event in rice and other cereals.

Gene duplication has been proposed as an accelerator of evolution. Ancient genome duplication events have been identified in diverse organisms, such as yeast, vertebrates, and Arabidopsis. Here, we have identified a whole genome duplication event (WGD) in the rice genome, which took place prior to the divergence of grasses about 70 million years ago (mya).
