Alzheimer's disease (AD) represents the major form of dementia in the elderly. In recent years, accumulating evidence indicate that obesity may act as a risk factor for AD, while the genetic link between the two conditions remains unclear. This bioinformatics analysis aimed to detect the genetic link between AD and obesity on single nucleotide polymorphisms (SNPs), gene, and pathway levels based on genome-wide association studies data. A total of 31 SNPs were found to be shared by AD and obesity, which were linked to 7 genes...

BACKGROUND: Atherogenic diabetes is associated with an increased cardiovascular risk and mortality in diabetic individuals; however, the impact of insulin resistance (IR) in lipid metabolism in preclinical stages is generally underreported. For that, we evaluated the capacity of IR to predict an atherogenic lipid subfraction profile. METHODS: Complete clinical evaluation and biochemical analysis (lipid, glucose profile, LDL, and HDL subfractions and LDL phenotype and size) were performed in 181 patients...

Eccentric exercise has been shown to exert beneficial effects in both lipid profile and insulin sensitivity. Antioxidant supplementation during chronic exercise is controversial as it may prevent the physiological training-induced adaptations. The aim of this study was to investigate: 1) the minimum duration of the eccentric exercise training required before changes on metabolic parameters are observed and 2) whether antioxidant supplementation during training would interfere with these adaptations. Sixteen young healthy men were randomized into the Vit group (1 g of vitamin C and 400 IU vitamin E daily) and the placebo (PL) group...

Maonan nationality is a relatively conservative and isolated minority in China. Little is known about the association of the Slit-Robo Rho GTPase activating protein 2 gene (SRGAP2) single nucleotide polymorphisms (SNPs) and serum lipid levels in the Chinese populations. This study was performed to clarify the association of the SRGAP2 rs2483058 and rs2580520 SNPs and their haplotypes with serum lipid traits in the Maonan and Han populations. Genotyping of the 2 SNPs was performed in 2444 unrelated subjects (Han, 1210 and Maonan, 1234) by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and then confirmed by direct sequencing...

The wyosine hypermodification found exclusively at G37 of tRNA(Phe) in eukaryotes and archaea is a very complicated process involving multiple steps and enzymes, and the derivatives are essential for the maintenance of the reading frame during translation. In the archaea Pyrococcus abyssi, two key enzymes from the Trm5 family, named PaTrm5a and PaTrm5b respectively, start the process by forming N1-methylated guanosine (m(1)G37). In addition, PaTrm5a catalyzes the further methylation of C7 on 4-demethylwyosine (imG-14) to produce isowyosine (imG2) at the same position...

BACKGROUND: Atherosclerosis is a chronic inflammatory disease of the artery wall where both innate and adaptive immunity play important roles. Modulation of the immune response against the stress protein antigen, heat shock protein (HSP) 60, by administration of mycobacterial HSP65 (mbHSP65) orally and/or nasally shows promising therapeutic results in young animals in the sense of less severe experimental atherosclerosis; however, the case of aged animals with already established atherosclerosis has so far never been investigated...

Vitamin B12 (cyanocobalamin, CNCbl) is an essential cofactor-precursor for two biochemical reactions in humans. When ingested, cobalamins (Cbl) are transported via a multistep transport system into the bloodstream, where the soluble protein transcobalamin (TC) binds Cbl and the complex is taken up into the cells via receptor mediated endocytosis. Crystal structures of TC in complex with CNCbl have been solved previously. However, the initial steps of holo-TC assembly have remained elusive. Here, we present four crystal structures of the beta domain of human TC (TC-beta) in different substrate-bound states...

BACKGROUND: COPD is a pulmonary disorder often accompanied by cardiovascular disease (CVD), and current treatment of this comorbidity is suboptimal. Systemic inflammation in COPD triggered by smoke and microbial exposure is suggested to link COPD and CVD. Mesenchymal stromal cells (MSC) possess anti-inflammatory capacities and MSC treatment is considered an attractive treatment option for various chronic inflammatory diseases. Therefore, we investigated the immunomodulatory properties of MSC in an acute and chronic model of lipopolysaccharide (LPS)-induced inflammation, emphysema and atherosclerosis development in APOE*3-Leiden (E3L) mice...

BACKGROUND: Bile leaks and anastomotic strictures are important complications of hepaticojejunostomy (HJ). Evidence suggests that the use of hepatic round ligament (HRL) to buttress HJ may be beneficial. This study evaluates the feasibility of this approach. METHODS: HJs performed over 2 years (Jun 2014- May 2016), with HRL reinforcement, were analyzed. Operative outcomes measured included technical difficulty, blood loss, time necessary for flap harvest, and reinforcement of HJ...

BACKGROUND: Increasing physical activity (PA) effectively in those who are inactive is challenging. For those who have subjective memory complaints (SMC) or mild cognitive impairment (MCI) this is a greater challenge necessitating the need for more engaging and innovative approaches. The primary aim of this trial is to determine whether a home-based 6-month PA intervention with individual goal-setting and peer mentors (GM-PA) can significantly increase PA levels in insufficiently active older adults at increased risk of developing Alzheimer's disease (AD)...

ApoE expression status was proved to be a highly specific marker of energy metabolism rate in the brain. Along with its neighbor, Translocase of Outer Mitochondrial Membrane 40 kDa (TOMM40) which is involved in mitochondrial metabolism, the corresponding genomic region constitutes the neuroenergetic hotspot. Using RNA-Seq data from a murine model of chronic stress a significant positive expression coordination of seven neighboring genes in ApoE locus in five brain regions was observed. ApoE maintains one of the highest absolute expression values genome-wide, implying that ApoE can be the driver of the neighboring gene expression alteration observed under stressful loads...

Introduction: Bacterial or viral diseases are one of the major causes of death in patients with chronic kidney disease (CKD). These patients show a quantitative reduction of levels of antibodies over time. Among the infectious diseases that affect CKD patients, stands out hepatitis B (HB). Immunization and control of antibodies levels against the hepatitis B surface antigen (anti-HBs) are ways to prevent the HB infection in this population. Patients with anti-HBs levels ≥10 IU/ml are considered adequate responders, whereas those with anti-HBs levels ≥ 100 IU/ml are considered excellent responders...

We describe a platform utilizing two methods based on hydrogen-deuterium exchange (HDX) coupled with mass spectrometry (MS) to characterize interactions between a protein and a small-molecule ligand. The model system is apolipoprotein E3 (apoE3) and a small-molecule drug candidate. We extended PLIMSTEX (protein-ligand interactions by mass spectrometry, titration, and H/D Exchange) to the regional level by incorporating enzymatic digestion to acquire binding information for peptides. In a single experiment, we not only identified putative binding sites, but also obtained affinities of 6...
