The Association Between Femoral Artery Intima-Media Thickness and Serum Glucagon-Like Peptide-1 Levels Among Newly Diagnosed Patients with Type 2 Diabetes Mellitus.

Introduction: Endothelium dysfunction and decrease of incretin effects occur early in type 2 diabetes mellitus and these changes contribute to diabetic cardiovascular complications such as atherosclerosis, thick intima-media, coronary, and peripheral arterial diseases. In patients with diabetes, the femoral artery is a site of a high incidence of injury in peripheral vascular diseases, and atherosclerotic changes may appear earlier in the femoral artery compared to the carotid artery. This study was conducted to determine the prevalence of increased femoral artery intima-media thickness (IMT) and atherosclerotic plaque and their correlation with serum glucagon-like peptide-1 (GLP-1) levels in newly-diagnosed patients with type 2 diabetes mellitus.

The Development and Characterization of Near-Isogenic and Pyramided Lines Carrying Resistance Genes to Brown Planthopper with the Genetic Background of Rice ( L.).

Water-soluble chitosan-derived sustainable materials: towards filaments, aerogels, microspheres, and plastics.

Bioinspired materials have aroused great interest as their inherent biocompatible and structural characteristics have given rise to sustainable applications. In this work, we have reported the phase and morphology transformation of chitosan from crystalline nanofibrils into amorphous sheets for fabricating sustainable materials. Acetylation-induced aqueous dissolution of native chitosan nanofibrils affords water-soluble chitosan as a biopolymeric liquid.

Chitin Liquid-Crystal-Templated Oxide Semiconductor Aerogels.

Chitin nanocrystals have been used as a liquid crystalline template to fabricate layered oxide semiconductor aerogels. Anisotropic chitin liquid crystals are transformed to sponge-like aerogels by hydrothermally cross-linked gelation and lyophilization-induced solidification. The hydrothermal gelation of chitin aqueous suspensions then proceeds with peroxotitanate to form hydrogel composites that recover to form aerogels after freeze-drying.

Structural characterization suggests models for monomeric and dimeric forms of full-length ezrin.

Ezrin is a member of the ERM (ezrin-radixin-moesin) family of proteins that have been conserved through metazoan evolution. These proteins have dormant and active forms, where the latter links the actin cytoskeleton to membranes. ERM proteins have three domains: an N-terminal FERM [band Four-point-one (4.

Fragmented implementation of maternal and child health home-based records in Vietnam: need for integration.

Background: Home-based records (HBRs) are globally implemented as the effective tools that encourage pregnant women and mothers to timely and adequately utilise maternal and child health (MCH) services. While availability and utilisation of nationally representative HBRs have been assessed in several earlier studies, the reality of a number of HBRs subnationally implemented in a less coordinated manner has been neither reported nor analysed.

Objectives: This study is aimed at estimating the prevalence of HBRs for MCH and the level of fragmentation of and overlapping between different HBRs for MCH in Vietnam.

Knowledge, attitude and practices: assessing maternal and child health care handbook intervention in Vietnam.

Background: Maternal and Child Health (MCH) Handbook, an integrated MCH home-based record, was piloted in four provinces of Vietnam (Dien Bien, Hoa Binh, Thanh Hoa and An Giang). The study is aimed at assessing the changes in pregnant women's behavior towards the frequencies of their antenatal care service utilizations and their subsequent breastfeeding practices up to six months of age, through the MCH Handbook intervention. This is because the levels of pregnant women's knowledge, attitude and practices (KAP) towards their antenatal care service utilizations and exclusive breastfeeding practices have been previously neither analyzed nor reported in relation to MCH home-based records in the country.

Semiquantitative and quantitative analysis of protein-DNA interactions using steady-state measurements in surface plasmon resonance competition experiments.

One method commonly used to characterize protein-DNA interactions is surface plasmon resonance (SPR). In a typical SPR experiment, chip-bound DNA is exposed to increasing concentrations of protein; the resulting binding data are used to calculate a dissociation constant for the interaction. However, in cases in which knowledge of the specificity of the interaction is required, a large set of DNA variants has to be tested; this is time consuming and costly, in part because of the requirement for multiple SPR chips.

New insights into DNA recognition by zinc fingers revealed by structural analysis of the oncoprotein ZNF217.

Classical zinc fingers (ZFs) are one of the most abundant and best characterized DNA-binding domains. Typically, tandem arrays of three or more ZFs bind DNA target sequences with high affinity and specificity, and the mode of DNA recognition is sufficiently well understood that tailor-made ZF-based DNA-binding proteins can be engineered. We have shown previously that a two-zinc finger unit found in the transcriptional coregulator ZNF217 recognizes DNA but with an affinity and specificity that is lower than other ZF arrays.

Characterization of a family of RanBP2-type zinc fingers that can recognize single-stranded RNA.

The recognition of single-stranded RNA (ssRNA) is an important aspect of gene regulation, and a number of different classes of protein domains that recognize ssRNA in a sequence-specific manner have been identified. Recently, we demonstrated that the RanBP2-type zinc finger (ZnF) domains from the human splicing factor ZnF Ran binding domain-containing protein 2 (ZRANB2) can bind to a sequence containing the consensus AGGUAA. Six other human proteins, namely, Ewing's sarcoma (EWS), translocated in liposarcoma (TLS)/FUS, RNA-binding protein 56 (RBP56), RNA-binding motif 5 (RBM5), RNA-binding motif 10 (RBM10) and testis-expressed sequence 13A (TEX13A), each contains a single ZnF with homology to the ZRANB2 ZnFs, and several of these proteins have been implicated in the regulation of mRNA processing.
