Abstract

Objectives To evaluate skeletal muscle mass in patients with both type 2 diabetes mellitus (T2DM) and concomitant lower extremity arterial disease (LEAD) and determine the contribution of skeletal muscle mass to macrovascular diseases.Methods In total, 112 patients with T2DM were divided into the T2DM and T2DM + LEAD groups. Hepatic function, renal function, uric acid, blood glucose, and glycated hemoglobin (HbA1C) were measured. Dual-energy X-ray absorptiometry was used to measure visceral fat area and skeletal muscle mass index (SMI).Results Waist-to-hip ratio, uric acid, and body fat percentage were significantly higher in the T2DM+LEAD group than in the T2DM group; SMI was significantly lower in the T2DM+LEAD group than in the T2DM group. There were no significant differences in albumin, creatinine, fasting blood glucose, HbA1C, or blood lipids. Uric acid, SMI, and body fat percentage were significantly positively correlated with T2DM and concomitant LEAD. Logistic regression analyses suggested that SMI is an independent risk factor for LEAD in T2DM (odds ratio = 1.517; 95% confidence interval: 1.082–2.126).Conclusions Skeletal muscle mass is lower in patients with T2DM and concomitant LEAD than in patients with T2DM who do not exhibit LEAD. SMI is an important risk factor for LEAD.

Abstract

Grain transportation plays an important role in many relief and emergency supply chains. In this paper, we take the grain emergency vehicle scheduling model between multiwarehouses as the research object. Under the emergency environment, the aim of the problem is to maximize the utilization of vehicles and minimize the delay time. The randomness of the key parameters in grain emergency vehicle scheduling, such as time and demand, is determined through statistical analysis and the model is solved through robust optimization method. Besides, we apply the numerical examples for experimental analysis. We compare the robust optimization model with classic model to illustrate the differences and similarities between them. The results show that the uncertainty of both time and demand has great influence on the efficiency of grain emergency vehicle scheduling problem.

Abstract

Civil air-transport, it's difficult to avoid the appearance of air disruption for many reasons. Aircraft mechanical problems, severe weather, crew sickness, airport curfews and security are the problems that force an airline to delay or even cancel their regular published flights. Air disruption not only affects the normal operation of the airlines, bringing many tourists trouble, but also makes huge economic losses to airlines, even affect the company's reputation. In this paper, we create the recovery network for every plane, model on the base of multi-commodity flow. We solve the model using column generation to minimize the cost. A number example is used to validate the correctness and efficiency of the method.

Abstract

Despite major progresses in genetic studies of hyperthermophilic archaea, recombinant protein production in these organisms always suffers from low yields and a robust expression system is still in great demand. Here we report a versatile vector that confers high levels of protein expression in Sulfolobus islandicus, a hyperthermophilic crenarchaeon. Two expression vectors, pSeSD and pEXA, harboring 11 unique restriction sites were constructed. They contain coding sequences of two hexahistidine (6×His) peptide tags and those coding for two protease sites, the latter of which make it possible to remove the peptide tags from expressed recombinant proteins. While pEXA employed an araS promoter for protein expression, pSeSD utilized P(araS-SD), an araS derivative promoter carrying an engineered ribosome-binding site (RBS; a Shine-Dalgarno [SD] sequence). We found that P(araS-SD) directed high levels of target gene expression. More strikingly, N-terminal amino acid sequencing of recombinant proteins unraveled that the protein synthesized from pEXA-N-lacS lacked the designed 6×His tag and that translation initiation did not start at the ATG codon of the fusion gene. Instead, it started at multiple sites downstream of the 6×His codons. Intriguingly, inserting an RBS site upstream of the ATG codon regained the expression of the 6×His tag, as shown with pSeSD-N-lacS. These results have yielded novel insight into the archaeal translation mechanism. The crenarchaeon Sulfolobus can utilize N-terminal coding sequences of proteins to specify translation initiation in the absence of an RBS site.

Abstract

Background: Chemerin is an important risk factor of insulin resistance. Non-alcoholic fatty liver has typical characteristics of insulin resistance. The aim of this study was to explore the potential role of chemerin in NAFLD., Methods: 45 subjects included 22 control subjects (A group) and 23 subjects diagnosed with non-alcoholic fatty liver disease (B group) participated in the study. 23 patients in the NAFLD group received oral daily metformin at a dose of 20 mg/kg/day for 24 weeks follow-up. Chemerin and insulin resistance markers were determined at baseline and 24 weeks., Results: The levels of WHR, BMI, FINS, HOMA-IR, TG, ALT, AST, and Chemerin in B group were significantly higher than A group. After 24 weeks of metformin treatment, the levels of WHR, AST, ALT, TG, chemerin and HOMA-IR were significantly reduced (p < 0.05) and other indexes were not changed significantly. Correlation analysis indicated that serum chemerin concentrations were positively correlated with BMI, WHR, HOMA-IR, FINS, TG, ALT, and AST levels. Logistic regression analysis showed chemerin, TG, and ALT were independent variables associated with NAFLD., Conclusions: These findings showed a significant increase of chemerin level in NAFLD patients. Metformin treatment can improve NAFLD and decrease the level of chemerin. Chemerin, TG, and ALT were independent variables associated with NAFLD.
