The Hippo pathway is an oncosuppressor signalling cascade that plays a major role in the control of cell growth, tissue homoeostasis and organ size. Dysregulation of the Hippo pathway leads to aberrant activation of the transcription co-activator YAP (Yes-associated protein) that contributes to tumorigenesis in several tissues. Here we identify glucocorticoids (GCs) as hormonal activators of YAP. Stimulation of glucocorticoid receptor (GR) leads to increase of YAP protein levels, nuclear accumulation and transcriptional activity in vitro and in vivo...

Little is known about the experiences of Vietnamese men who have sex with men in accessing HIV testing and treatment. We aimed to explore barriers to access and uptake of antiretroviral therapy (ART) among HIV-positive men who have sex with men in Hanoi. During 2015, we conducted qualitative interviews with 35 participants recruited using snowball sampling based on previous research and social networks. Key individual impediments to ART uptake included inadequate preparation for a positive diagnosis and the dual stigmatisation of homosexuality and HIV and its consequences, leading to fear of disclosure of HIV status...

IgE antibodies are key mediators of anti-parasitic immune responses, but their potential for cancer treatment via antibody-directed cell-mediated cytotoxicity (ADCC) has been little studied. Recently, tumor antigen-specific IgEs were reported to restrict cancer cell growth by engaging high-affinity Fc receptors on monocytes and macrophages, however, the underlying therapeutic mechanisms were undefined and in vivo proof-of-concept was limited. Here, an immunocompetent rat model was designed to recapitulate the human IgE-Fcε receptor system for cancer studies...

BACKGROUND: When performing arthroscopic ankle arthrodesis for end-stage ankle arthritis, internal fixation is performed using bone screws after appropriate preparation. However, optimal characteristics of bone screws have not been examined in terms of pressure force. Objective comparisons of bone-screw performance may provide information on procedures for arthroscopic ankle arthrodesis. The study objectives were to determine whether it was possible to measure compressive force changes using the newly developed device and to infer all screw characteristics from measurement results when used in actual surgeries...

Negative racial stereotypes tend to associate Black people with threat. This often leads to the misidentification of harmless objects as weapons held by a Black individual. Yet, little is known about how bodily states impact the expression of racial stereotyping. By tapping into the phasic activation of arterial baroreceptors, known to be associated with changes in the neural processing of fearful stimuli, we show activation of race-threat stereotypes synchronized with the cardiovascular cycle. Across two established tasks, stimuli depicting Black or White individuals were presented to coincide with either the cardiac systole or diastole...

BACKGROUND AND AIMS: Hypoxia inducible factor 1 alpha subunit (HIF1A) is a transcription factor that controls the cellular response to hypoxia and is activated in hepatocytes of patients with non-alcoholic fatty liver disease (NAFLD). NAFLD increases risk for cholesterol gallstone disease by unclear mechanisms. We studied the relationship between HIF1A and gallstone formation associated with liver steatosis. METHODS: We performed studies with mice with inducible disruption of Hif1a in hepatocytes, via a Cre adenoviral vector (iH-HIFKO mice), and mice without disruption of Hif1a (control mice)...

Individuals differ in their awareness of afferent information from within their bodies, which is typically assessed by a heartbeat perception measure of 'interoceptive accuracy' (IAcc). Neural and behavioural correlates of this trait have been investigated, but a theoretical explanation has yet to be presented. Building on recent models that describe interoception within the free energy/predictive coding framework, this paper applies similar principles to IAcc, proposing that individual differences in IAcc depend on 'precision' in interoceptive systems, i...

Interoception refers to the sensing of the internal state of one's body. Interoception is distinct from the processing of sensory information concerning external (non-self) stimuli (e.g. vision, hearing, touch and smell) and is the afferent axis to internal (autonomic and hormonal) physiological control. However, the impact of interoception extends beyond homeostatic/allostatic reflexes: it is proposed to be fundamental to motivation, emotion (affective feelings and behaviours), social cognition and self-awareness...

Platinum(ii) complexes of the formula PtLCl2 [L = 2-(2'-pyridyl)quinoxaline, (pqx) (1), 2,(2'-pyridyl)benzo[g]quinoxaline, (pbqx) (3) and 2,(2'-pyridyl)quinoline, (pqn) (5)] were synthesized and characterized by spectroscopic and X-ray diffraction methods. Also, monodentate coordination of the ligands pqx and pbqx formed the complexes trans-Pt(DMSO)pqxCl2 (2) and trans-Pt(DMSO)pbqxCl2 (4) as it is indicated from X-ray crystal structure and NMR studies. The reaction of the complexes (1), (3) and (5) with DMSO-d6 revealed a ligand-release solvolysis, which was studied by means of NMR techniques...

Capsules with a liquefied core were fabricated via the assembly of polymeric droplets induced by superamphiphobic surfaces. These highly repellent substrates exhibit distinct features such as (i) an easy and precise control over the particle size and shape, (ii) a high encapsulation efficiency, (iii) mild processing conditions, and (iv) the possibility to include any object in either a water or oil-based liquid core, which are not found on the current available strategies. As proof of concept, a photo-cross-linkable derivative of chitosan was used to produce the polymeric shell while a wealth variety of template cores were tested using a reversible cross-linking mechanism, interfacial gelation process or ice...

Sensory neuroscience seeks to understand and predict how sensory neurons respond to stimuli. Nonlinear components of neural responses are frequently characterized by the second-order Wiener kernel and the closely-related spike-triggered covariance (STC). Recent advances in data acquisition have made it increasingly common and computationally intensive to compute second-order Wiener kernels/STC matrices. In order to speed up this sort of analysis, we developed a graphics processing unit (GPU)-accelerated module that computes the second-order Wiener kernel of a system's response to a stimulus...

A previous genome-wide association study (GWAS) performed in 963 Japanese individuals (487 primary biliary cholangitis [PBC] cases and 476 healthy controls) identified TNFSF15 (rs4979462) and POU2AF1 (rs4938534) as strong susceptibility loci for PBC. In this study, we performed GWAS in an additional 1,923 Japanese individuals (894 PBC cases and 1,029 healthy controls), and combined the results with the previous data. This GWAS, together with a subsequent replication study in an independent set of 7,024 Japanese individuals (512 PBC cases and 6,512 healthy controls), identified PRKCB (rs7404928) as a novel susceptibility locus for PBC (odds ratio [OR] = 1...

Bile acids, the metabolites of cholesterol, are signaling molecules that play critical role in many physiological functions. They undergo enterohepatic circulation through various transporters expressed in intestine and liver. Human organic anion-transporting polypeptides (OATP) 1B1 and OATP1B3 contribute to hepatic uptake of bile acids such as taurocholic acid. However, the transport properties of individual bile acids are not well understood. Therefore, we selected HEK293 cells overexpressing OATP1B1 and OATP1B3 to evaluate the transport of five major human bile acids (cholic acid, chenodeoxycholic acid, deoxycholic acid, ursodeoxycholic acid, lithocholic acid) together withtheir glycine and taurine conjugates via OATP1B1 and OATP1B3...

In Germany, the reported syphilis prevalence has increased continuously since 2010, with a total of 6834 syphilis cases being reported in 2015. The largest increase of reported syphilis occurred in men who have sex with men (MSM). The antibiotic agent of choice for treatment of syphilis is still penicillin. There are no penicillin-resistant Treponema pallidum strains. Alternatives are ceftriaxone and doxycycline. In Germany, azithromycin is not approved for treatment of syphilis; however, therapy failures are increasingly reported...

Using a high-throughput approach, we identified lemur tyrosine kinase 2 (LMTK2) as a novel determinant of cell sensitivity to TRAIL. LMTK2 is a poorly characterized serine/threonine kinase believed to play a role in endosomal membrane trafficking and neuronal physiology, and recently found to be mutated in diverse tumor types. We show that LMTK2 silencing sensitizes immortalized epithelial cells and cancer cells to TRAIL, and this phenomenon is accompanied by changes in the expression of BCL2 family members...

Extracellular administration of water-soluble and membrane-permeant analogs of phosphatidylinositol phosphates (PIPs) is a useful strategy for understanding the cellular roles of PIPs as well as the mode of action of drugs whose biological activity is associated with PIPs. We herein established the synthetic route to the dioctanoyl analogue of phosphatidylinositol 3,5-bisphosphate (di-C8-PI(3,5)P2) and its penta(acetoxymethyl) ester (di-C8-PI(3,5)P2/5AM).
