BACKGROUND: Renal cell carcinoma (RCC) is one of the most common types of cancer in developed countries. Bone marrow stromal cell antigen 2 (BST2) gene, which encodes BST2 transmembrane glycoprotein, is overexpressed in several cancer types. In the present study, we analyzed the expression and function of BST2 in RCC. MATERIALS AND METHODS: BST2 expression was analyzed by immunohistochemistry in 123 RCC cases. RNA interference was used to inhibit BST2 expression in a RCC cell line...

SDF-1/CXCR4 activation facilitates myocardial repair. Therefore, we aimed to activate the HIF-1α target genes SDF-1 and CXCR4 by dimethyloxalylglycine (DMOG)-induced prolyl-hydroxylase (PH) inhibition to augment CXCR4+ cell recruitment and myocardial repair. SDF-1 and CXCR4 expression was analyzed under normoxia and ischemia ± DMOG utilizing SDF-1-EGFP and CXCR4-EGFP reporter mice. In bone marrow and heart, CXCR4-EGFP was predominantly expressed in CD45+/CD11b+ leukocytes which significantly increased after myocardial ischemia...

BACKGROUND: Breast cancer radiotherapy increases the risk of heart failure (HF) with preserved ejection fraction (HFpEF). Cardiomyocytes are highly radio-resistant but radiation specifically affects coronary microvascular endothelial cells with subsequent microvascular inflammation and rarefaction. The effects of radiation on left ventricular (LV) diastolic function are poorly characterized. We hypothesized that cardiac radiation exposure may result in diastolic dysfunction without reduced EF...

Understanding virus-host interactions is crucial for vaccine development. This study investigates such interactions using fluorescent nanodiamonds (FNDs) coated with vaccinia envelope proteins as the model system. To achieve this goal, we noncovalently conjugated 100-nm FND with A27(aa 21-84), a recombinant envelope protein of vaccinia virus, for glycosaminoglycans (GAGs)-specific targeting and imaging of living cells. Another recombinant protein A27(aa 33-84) that removes the GAGs-binding sequences was also used for comparison...

BACKGROUND: A few bioactivities of constituents from Gynostemma laxum, which has been collected in Vietnam, have been reported until now. There is no report about the effects of constituents from G. laxum although the nuclear factor (erythroid-derived 2)-like 2 (Nrf2)-mediated heme oxygenase-1 (HO-1) antioxidant defense system is involved in neuroprotection in the brain. Therefore, we investigated whether quercetin (2), benzoic acid (10) and their analogues (1, 3-9 and 11) from G. laxum have the antioxidant and neuroprotective activities and also their underlying mechanism...

The forced oscillation technique (FOT) can provide unique and clinically relevant lung function information with little cooperation with subjects. However, FOT has higher variability than spirometry, possibly because strategies for quality control and reducing artifacts in FOT measurements have yet to be standardized or validated. Many quality control procedures either rely on simple statistical filters or subjective evaluation by a human operator. In this study, we propose an automated artifact removal approach based on the resistance against flow profile, applied to complete breaths...

This study compared the efficacy and safety of a human acellular dermal matrix (ADM), D-ADM, with a conventional care arm and an active comparator human ADM arm, GJ-ADM, for the treatment of chronic diabetic foot ulcers. The study design was a prospective, randomized controlled trial that enrolled 168 diabetic foot ulcer subjects in 13 centers across 9 states. Subjects in the ADM arms received one application but could receive one additional application of ADM if deemed necessary. Screen failures and early withdrawals left 53 subjects in the D-ADM arm, 56 in the conventional care arm, and 23 in the GJ-ADM arm (2:2:1 ratio)...

AIMS: Cell matrix modulating protein SPARCL-1 is highly expressed by astrocytes during CNS development and following acute CNS damage. Applying NanoLC-MS/MS to CSF of RRMS and SPMS patients, we identified SPARCL-1 as differentially expressed between these two stages of MS, suggesting a potential as CSF biomarker to differentiate RRMS from SPMS and a role in MS pathogenesis. METHODS: This study examines the potential of SPARCL-1 as CSF biomarker discriminating RRMS from SPMS in 3 independent cohorts (n=249), analyses its expression pattern in MS lesions (n= 26), and studies its regulation in cultured human brain microvasculature endothelial cells (BEC) after exposure to MS-relevant inflammatory mediators...

The enzymes that determine protein O-GlcNAcylation, O-GlcNAc transferase (OGT) and O-GlcNAcase (OGA), act on key transcriptional and epigenetic regulators and both are abundantly expressed in the brain. However, little is known about how alterations in O-GlcNAc cycling affect human embryonic stem cell (hESC) neural differentiation. Here, we studied the effects of perturbing O-GlcNAcylation during neural induction of hESCs using the metabolic inhibitor of OGT, peracetylated 5-thio-N-acetylglucosamine (Ac4-5SGlcNAc)...

Immunoglobulin (Ig) affinity maturation depends on somatic hypermutation (SHM) in variable (V) regions initiated by activation-induced cytidine deaminase (AID). AID induces transition mutations by C→U deamination on both strands, causing C:G→T:A. Error-prone repairs of U by base excision and mismatch repairs create transversion mutations at C/G and mutations at A/T sites. In Neuberger's model, it remained to clarify how transition/transversion repair is regulated. We investigate role of AID-interacting GANP (germinal-center associated nuclear protein) in IgV SHM profile...

Interventions are needed to address frailty and other behaviors (e.g., drug and alcohol use) among prefrail and frail homeless women (P/FHW). The purpose of this pilot randomized controlled trial (RCT) was to compare the efficacy of a Frailty Intervention (FI) versus a Health Promotion (HP) program among P/FHW (N = 32). Structured instruments assessed sociodemographics, individual, situational, health-related, and behavioral factors. While program differences were not statistically significant with the main outcome variables, medium-to-large effect sizes were found in favor of the HP program as it relates to physical and overall frailty, as well as, any drug use, alcohol use, and drug dependency...

Newly emerged molecular markers in gliomas provide prognostic values beyond the capabilities of histologic classification. BRAF mutation, especially BRAF V600E, is common in a subset of gliomas and may represent a potential prognostic marker. The aim of our study is to investigate the potential use of BRAF mutations on prognosis of glioma patients. Four electronic databases were searched for potential articles, including PubMed, Scopus, ISI Web of Science, and Virtual Health Library (VHL). Data of hazard ratio (HR) for overall survival (OS) and progression-free survival (PFS) were directly obtained from original papers or indirectly estimated from Kaplan Meier curve (KMC)...

PURPOSE: There is some evidence that eating disorders (ED) and Attention-deficit/hyperactivity disorder (ADHD) share common clinical features and that ADHD might contribute to the severity of eating disorders. A greater understanding of how the presence of comorbid ADHD may affect the psychopathological framework of eating disorder seems of primary importance. The aim of our study was to evaluate rates of ADHD in three ED subgroups of inpatients: anorexia nervosa restricting type (AN-R), anorexia nervosa binge-eating/purging type (AN-BP) and bulimia nervosa (BN)...

BACKGROUND: Poor antiretroviral therapy (ART) adherence leads to drug resistance and treatment failures. The options for second and third line ART regimens, particularly for pediatric patients, are very limited in low and middle-income countries. HIV-infected children are mostly passive drug-takers, thus caretakers play a very important role in assuring ART adherence. Pediatric ART adherence is still a challenging problem in Vietnam since non-adherence is the major risk factor for treatment failure...
