BACKGROUND: Neonatal adiposity has many determinants and may be a risk factor for future obesity. Epigenetic regulation of metabolically important genes is a potential contributor. OBJECTIVES: The objective of the study is to determine whether methylation changes in the LEP gene in cord blood DNA are impacted by the maternal environment or affect neonatal adiposity measures. METHODS: A cross-sectional study of 114 full-term neonates born to healthy mothers with normal glucose tolerance was performed...

BACKGROUND: Follicular lymphoma (FL) is an indolent non-Hodgkin lymphoma that has a risk of transformation to more aggressive lymphoma. Relatively little is known about the non-malignant B-cell and T-cell subset composition within the tumor microenvironment and whether altered phenotypes are associated with patterns of lymphoma B-cell heterogeneity. METHODS: Two mass cytometry (CyTOF) panels were designed to immunophenotype B and T cells in FL tumors. Populations of malignant B cells, non-malignant B cells, and T cells from each FL tumor were identified and their phenotypes compared to B and T cells from healthy human tonsillar tissue...

'Black' TiO2 -in the widest sense, TiO2 reduced by various treatments-has attracted tremendous scientific interest in recent years because of some outstanding properties; most remarkably in photocatalysis. While the material effects visible light absorption (the blacker, the better), black titania produced by high pressure hydrogenation was recently reported to show another highly interesting feature; noble-metal-free photocatalytic H2 generation. In a systematic investigation of high-temperature hydrogen treatments of anatase nanoparticles, TEM, XRD, EPR, XPS, and photoelectrochemistry are used to characterize different degrees of surface hydrogenation, surface termination, electrical conductivity, and structural defects in the differently treated materials...

Recent advances in combining flow cytometry and mass spectrometry have led to the development of mass cytometry, allowing for the interrogation of complex cell populations on an unprecedented scale. The volumes and high dimensionality of mass cytometry data pose significant challenges in terms of analysis and visualization. We implement a method called Radviz (1-3), where multidimensional single cell data can be visualized as a projection that maintains the original dimensions and data complexity whilst facilitating analysis and visualization...

When an aqueous NaCl solution with low concentrations of transition metal ions is frozen, most of the solutes are concentrated in the freeze concentrated solutions (FCS). However, Zn2+ is often accumulated at sites where other elements are not detected. X-ray absorption near-edge structure spectroscopy at the Zn K-edge indicates the formation of ZnO. A possible mechanism for the ZnO formation is discussed.

BACKGROUND: Diagnosis of hepatoblastoma (HBL) is based on characteristic clinical and radiological presentation, young age and marked elevation of serum α-fetoprotein (aFP). Fine needle aspiration (FNA) technique is successfully used in the diagnosis of hepatoblastoma. To evaluate the value of FNA in the diagnosis and subtyping of HBL, we report our experience correlated to histological sections (core needle biopsy, CNB). METHODS: From 1991 to 2015, 21 cases from 20 patients were cytologically diagnosed as HBL...

Proteinases are enzymes that can digest other proteins. In chronic wounds, a sub-class of these enzymes with the ability to degrade the extracellular matrix (matrix metalloproteinases, MMPs) have been found to both inhibit healing and to be able to aid in enzymatically debriding a wound. Enzymatic debridement using the enzymes present in a wound is generally called autolytic debridement. Clinicians seeking to employ autolytic debridement typically use occlusive materials such as medical honey, alginate dressings and other occlusive dressings...

Transition of a physiological folded prion (PrP(C) ) into a pathogenic misfolded prion (PrP(S)(c) ) causes lethal neurodegenerative disorders and prion diseases. Anti-prion compounds have been developed to prevent this conversion; however, their mechanism of action remains unclear. Recently, we reported two anti-prion compounds, BMD29 and 35, identified by in silico and in vitro screening. In this study, we used extensive explicit-solvent molecular dynamics simulations to investigate ligand binding inhibition by anti-prion compounds in prion folding over misfolding behavior at acidic pH...

Danazol, the established clinical drug has given promising therapeutic results in a series of clinical trials with breast cancer patients. Danazol shares structural similarities with several known PKC agonists and fits well into the C1 domain. Danazol binds to the C1b domain of PKC with Kd of 5.64±1.27 μM. MD simulation studies further support that the PKC-Danazol molecular model is stable and showing minimum distortion to the structure during the simulation period. Immunofluorescence and western-blotting studies indicate that MDAMB-231 cells stimulated with danazol exhibit translocation of PKCα to the plasma membrane...

BACKGROUND AND OBJECTIVES: Assessment of the effects of long-term management on patient quality of life (QOL) would be extremely useful for determining asthma treatment strategies. However, no studies have evaluated QOL over an extended period of time. This study evaluated the changes in QOL, drug management and disease severity in the same asthma patients at an interval of approximately 9 years. METHODS: We re-surveyed asthma patients enrolled in a survey conducted in 2004 to evaluate the effects of approximately a decade of treatment on disease severity and QOL assessed by the Japanese Asthma Health Questionnaire (AHQ-JAPAN)...

A series of 18 novel N-Mannich bases derived from 5-adamantyl-1,2,4-triazole-3-thione was synthesized and characterized using NMR spectroscopy and X-ray diffraction technique. All derivatives were evaluated for their anticancer potential against four human cancer cell lines. Several tested compounds exerted good cytotoxic activities on K562 and HL-60 cell lines, along with pronounced selectivity, showing lower cytotoxicity against normal fibroblasts MRC-5 compared to cancer cells. The effects of compounds 5b, 5e and 5j on the cell cycle were investigated by flow cytometric analysis...

BACKGROUND: Medical students traditionally learn physical examination skills as a rote list of manoeuvres. Alternatives like hypothesis-driven physical examination (HDPE) may promote students' understanding of the contribution of physical examination to diagnostic reasoning. We sought to determine whether first-year medical students can effectively learn to perform a physical examination using an HDPE approach, and then tailor the examination to specific clinical scenarios. Medical students traditionally learn physical examination skills as a rote list of manoeuvres CONTEXT: First-year medical students at the University of Minnesota were taught both traditional and HDPE approaches during a required 17-week clinical skills course in their first semester...

The aim of this study was to identify characteristics independently associated with a higher risk of developing skin damage because of incontinence [incontinence-associated dermatitis (IAD) category 2] in nursing home residents. As part of a larger randomised controlled trial, IAD incidence was monitored for 1 month in a sample of 381 incontinent residents using a validated IAD Severity Categorisation Tool. Data on demographical, physical, functional and psychological characteristics were collected. The overall IAD incidence (category 1-2) was 30·0%, and 6% of the participants developed skin damage (IAD category 2)...

Quinacrine - the drug based on 9-aminoacridine - failed in clinical trials for prion diseases, whereas it was active in in-vitro studies. We hypothesize that aromatic nucleophilic substitution at C9 could be contributing factor responsible for this failure because of the transfer of acridine moiety from quinacrine to abundant glutathione. Here, we described the semi-large-scale synthesis of the acridinylated glutathione and the consequences of its formation on biological and biophysical activities. The acridinylated glutathione is one order of magnitude weaker prion protein binder than the parent quinacrine...

Temporal changes in magnitude of effect sizes reported in many areas of research are a threat to the credibility of the results and conclusions of meta-analysis. Numerous sequential methods for meta-analysis have been proposed to detect changes and monitor trends in effect sizes so that meta-analysis can be updated when necessary and interpreted based on the time it was conducted. The difficulties of sequential meta-analysis under the random-effects model are caused by dependencies in increments introduced by the estimation of the heterogeneity parameter τ(2) ...

BACKGROUND: In Australia, the extensive use of clethodim for the control of Lolium rigidum has resulted in the evolution of many clethodim-resistant L.rigidum populations. Five clethodim-resistant populations of L. rigidum were analysed for the inheritance of clethodim resistance. RESULTS: Reciprocal crosses were made between resistant (R) and susceptible (S) populations. Within crosses, dose responses of reciprocal F1 families of all populations, except A61 were similar each other, indicating clethodim resistance in these populations is encoded on the nuclear genome...
