Multiple factors have been considered to play a role in the development of benign prostatic hyperplasia (BPH), including chronic inflammation, hormones, and epithelial-mesenchymal transition (EMT). Inflammation is regarded as one of the potential inducers of EMT. However, the mechanisms, modulating pro-inflammatory factors (IL-6 and TGF-β1) induce EMT features, have not yet been studied in BPH. In this study, we investigated whether DNA methyltransferases1 (DNMT1) could regulate IL-6 and TGF-β1 induce EMT...

The nutritional essentialities of transition element vanadium (V) as micro-nutrient in farm animals have not yet been established, though in rat model, vanadium as vanadate has been reported to exert insulin-mimetic effect and shown to be needed for proper development of bones. The objective of this study was to determine the effect of V supplementation on growth performance, plasma hormones and bone health status in calves. Twenty-four crossbred calves (body weight 72.83 ± 2.5 kg; age 3-9 months) were blocked in four groups and randomly assigned to four treatment groups (n = 6) on body weight and age basis...

This paper explores the content and extent of the burden of caregiving for Chinese families in transition. It sets out to understand how Chinese families manage to balance family caregiving responsibilities with employment, the impact of the existing social institutions on family caregiving practices, and the risks that caregivers have to face. Data were collected from a sample of 214 workers from 14 manufacturing companies in an industrialized city in central China in 2013. Analysis revealed that common types of eldercare were assisting with activities of daily living and medical related care; middle aged employed respondents were most likely to be the caregivers to older family members; financial and time demands of care were challenging for caregivers, but women with more education and a secure job responded to the pressure of care giving better than those with less education and insecure jobs...

Cationic, anionic and non-ionic hydrogels having acrylamide polymer backbones were synthesized via free radical polymerization with N,N-methylenebisacrylamide (BIS) as crosslinker. The chemical structures of the hydrogels were characterized by Fourier Transform Infrared Spectroscopy (FTIR). Physicochemical properties such as swelling kinetic, maximum swelling capacity, volume phase transition temperature (VPTT) and wettability (static water contact angle) of hydrogels swollen in aqueous and cell culture medium, at room and cell culture temperatures were studied...

We probe counter-ion specific effects in nano-confined electrical-double-layers (EDLs) by means of direct force measurements across a model slit pore in the extended surface forces apparatus. By variation of solution composition, we compare four different counter-ions with dissimilar hydration properties, namely Na(+), K(+), Cs(+) as well as H3O(+), all confined between (001) mica surfaces. We discuss the results in terms of a recently proposed π-transition model, evoking hydrated ion layering as the recurrent structural element in highly confined EDLs...

The effects of carbon quantum dots (CQDs) on the dynamic properties of bovine serum albumin (BSA) were investigated using pendant drop profile analysis method. Moreover, the effects of CQDs on the competitive adsorption of BSA and dipalmitoyl phosphatidylcholine (DPPC) were examined. CQDs reduce the fluorescence intensity of BSA and cause a red shift in fluorescence emission. The quenching constant at pH 4.3 is almost twice as large as that of the value obtained at pH 6.0. A small amount of CQDs does not influence the dynamic surface adsorption properties of BSA molecules...

Sodium dodecylsulfate (SDS) - a simple single tailed surfactant (STS) can form stable vesicles from its micellar solution without any additives under the mediation of solid surfaces. To further understand the mechanism of this transition on the molecular level, molecular dynamics simulations are performed to study segments of SDS bilayers (as part of vesicles) in the bulk solution systematically, at the moment that the lower leaflet of bilayers already detached from solid surfaces. The SDS membrane would rather keep their bilayers structure than return to micelles when the initial interdigitated degree (δi) between alkyl chains is more than 8...

Cu2SnS3 (CTS) thin films have been successfully deposited on a cost-effective stainless steel substrate by simple and inexpensive chemical bath deposition (CBD) method. The films are deliberated in provisos of their structural, morphological, optical and photoelectrochemical (PEC) properties before and after annealing treatment, using various physico-chemical techniques. The XRD studies showed the formation of triclinic phase of CTS films with nanocrystalline structure. Also, the crystallinity is enhanced with annealing and the secondary phase of Cu2S observed...

An in-silico system to encode structure, bonding and properties of coordination complexes is developed. The encoding is achieved through a semantic XML markup frame. Composition of the coordination complexes is captured in terms of central atom and ligands. Structural information of central atom is detailed in terms of electron status of valence electron orbitals. The ligands are encoded with specific reference to the electron environment of ligand centre atoms. Behaviour of ligands to form low or high spin complexes is accomplished by assigning a Ligand Centre Value to every ligand based on the electronic environment of ligand centre atom...

BACKGROUND AND AIMS: Small bowel and colorectal muscle biopsies require a surgical approach. Advancing our understanding of the pathophysiology of motility disorders, such as functional bowel disorders, intestinal pseudo-obstruction and slow transit constipation, is hindered by our inability to non-invasively obtain muscularis propria (MP) for evaluation of multiple cell types, including myenteric neurons. The aims of this study were to determine (1) technical feasibility, reproducibility and safety of performing duodenal endoscopic muscle biopsy (dEMB) and rectal endoscopic muscle biopsy (rEMB) using a clip-assist technique; and (2) presence of myenteric neurons in tissue samples...

Cancer is a life-threatening disease, and the occurrence of metastasis, which increases the lethality of primary tumors, is increasing. The epithelial-to-mesenchymal transition (EMT) is a biological process by which epithelial cells lose cell-cell adhesion properties and acquire mesenchymal properties, including motility and invasiveness. EMT is considered an early stage of metastasis; therefore, inhibiting EMT may be an effective anticancer therapy. In the present study, the antimetastatic effect of piperlongumine (PL) was assessed in human cancer cells...

BACKGROUND: The reason for declining risk to psychosis across individuals assessed and meeting Ultra High Risk (UHR) criteria is still unclear. No studies have investigated the potential substantial role of the underlying risk enrichment across all the individuals undergoing an UHR assessment. METHODS: Cohort study including all non-psychotic subjects who were assessed on suspicion of psychosis risk by the OASIS UHR service in the period 2001 to 2015. Posttest (after UHR assessment) and pretest risk (before UHR assessment) of psychosis were stratified and compared across three time periods (2001-2005, 2006-2010, 2011-2015) with Cox analysis and modulating factors were investigated...

The central amygdala (CeA) GABAergic system is hypothesized to drive the development of alcohol dependence, due to its pivotal roles in the reinforcing actions of alcohol and the expression of negative emotion, anxiety and stress. Recent work has also identified an important role for the CeA corticotropin-releasing factor (CRF) system in the interaction between anxiety/stress and alcohol dependence. We have previously shown that acute alcohol and CRF each increase action potential-independent GABA release in the CeA via their actions at presynaptic CRF type 1 receptors (CRF1s); however, the shared mechanism employed by these two compounds requires further investigation...

BACKGROUND: Epithelial to mesenchymal transition (EMT) is considered to be important for cancer invasion and metastasis. Tumour hypoxia, in addition to Transforming Growth Factor-β (TGF-β) and Notch, amongst others, have been suggested to be involved in EMT. We therefore investigated if hypoxia, TGF-β1 and the Notch ligand Jagged-1 alone induced morphological changes with corresponding EMT signatures in different epithelial breast cancer cell lines in vitro. Furthermore, we also studied whether or not TGF-β1, or Jagged-1 in combination with hypoxia added any effect on EMT...

Hydration forces between DNA molecules in the A- and B-Form were studied using a newly developed technique enabling simultaneous in situ control of temperature and relative humidity. X-ray diffraction data were collected from oriented calf-thymus DNA fibers in the relative humidity range of 98%-70%, during which DNA undergoes the B- to A-form transition. Coexistence of both forms was observed over a finite humidity range at the transition. The change in DNA separation in response to variation in humidity, i...

BACKGROUND: Japan has entered the era of super-ageing and advanced health transition, which is increasingly putting pressure on the sustainability of its health system. The level and pace of this health transition might vary across regions within Japan and concern is growing about increasing regional variations in disease burden. The Global Burden of Diseases, Injuries, and Risk Factors Study 2015 (GBD 2015) provides a comprehensive, comparable framework. We used data from GBD 2015 with the aim to quantify the burden of disease and injuries, and to attribute risk factors in Japan at a subnational, prefecture-level...

Megan E Gray, Phillip Nieburg, Rebecca Dillingham
Children and adolescents living with human immunodeficiency virus (HIV) represent a population that requires a unique approach to HIV care. Prevention, testing, initiation of antiretroviral therapy (ART), and retention and engagement in care are critical steps. Each step requires providers to address age-specific barriers, so that successful and prolonged viral suppression can occur. Adherence to ART, disclosure of HIV-positive status, and stigma are examples of struggles faced by youth, their families, and health care providers...

In this paper, we propose a new strategy for retrospective identification of feed phases from online sensor-data enriched feed profiles of an Escherichia Coli (E. coli) fed-batch fermentation process. In contrast to conventional (static), data-driven multi-class machine learning (ML), we exploit process knowledge in order to constrain our classification system yielding more parsimonious models compared to static ML approaches. In particular, we enforce unidirectionality on a set of binary, multivariate classifiers trained to discriminate between adjacent feed phases by linking the classifiers through a one-way switch...

Multi-energy calibration (MEC) is a novel strategy that explores the capacity of several analytes of generating analytical signals at many different wavelengths (transition energies). Contrasting with traditional methods, which employ a fixed transition energy and different analyte concentrations to build a calibration plot, MEC uses a fixed analyte concentration and multiple transition energies for calibration. Only two calibration solutions are required in combination with the MEC method. Solution 1 is composed of 50% v v(-1) sample and 50% v v(-1) of a standard solution containing the analytes...
