By reducing APC, decreases in drinking among heavy drinkers as well as among ordinary drinkers will lead to fewer alcohol-related harms. The evidence strongly suggests public health gains from universal policies targeting APC. Reducing APC is furthermore an investment in future public health, as it is likely an efficient way of preventing people from becoming very heavy drinkers, who may cause themselves and others severe health and social problems.

Timely HIV testing has significant implications for HIV prevention and management. Newer HIV testing approaches, namely provider-initiated testing and counselling (PITC), HIV rapid testing (HIV RT) and HIV self-testing (HIV ST), aim to reach those populations most at risk and, particularly, those who have not previously tested for HIV.

This study used semi-structured interviews to examine the (un)acceptability, barriers and facilitators to newer HIV testing approaches (i.e. PITC, HIV RT and HIV ST) among Vietnamese-born migrants (n = 10) in greater-Brisbane, Queensland, Australia.

Vietnamese-born migrants had mixed perspectives on the (un)acceptability of newer HIV testing approaches. PITC was largely viewed by participants as a facilitator to HIV testing for Vietnamese-born migrants. Likewise, HIV RT (undertaken by a doctor in a medical setting, as opposed to a trained community member in a community setting) was generally considered to facilitate HIV testing. HIV ST was largely not considered acceptable to Vietnamese-born migrants and they would prefer to go to a doctor for HIV testing. Several factors were identified that either facilitate or act as barriers to newer HIV testing approaches, including privacy; cost of (accessing) HIV testing; comfort and convenience; healthcare provider relationship; risk perception; symptoms; and technical and emotional support.

There is a need to understand migrants' HIV testing preferences if poorer HIV-related outcomes are to be overcome. selleckchem The findings from this study show a preference for doctor-centred HIV testing, due to enhanced privacy, accuracy and support.

Inducible heat shock protein A1A (HSPA1A) is a member of the 70-kDa heat shock protein A (HSPA) family, which acts as a chaperone to regulate proteostasis; however, HSPA1A also participates as a cytokine in inflammatory regulation, leading to its designation as a chaperokine. This study examined the spatiotemporal expression of HSPA1A protein in the rat myometrium throughout gestation and assessed whether it is secreted as cargo of myometrial cell-derived extracellular vesicles (EVs). Immunoblot analysis demonstrated that HSPA1A expression was markedly elevated during late pregnancy and labour and increased by uterine distension. Myometrial HSPA1A expression insitu increased in myocytes of longitudinal and circular muscle layers from Day 19 through to postpartum, specifically in the cytoplasm and nuclei of myocytes from both muscle layers, but frequently detectable just outside myocyte membranes. Scanning electron microscopy examination of samples isolated from hTERT-HM cell-conditioned culture medium, using EV isolation spin columns, confirmed the presence of EVs. EV lysates contained HSPA8, HSPA1A and the EV markers apoptosis-linked gene 2-interacting protein X (Alix), the tetraspanin cluster of differentiation 63 (CD63), tumour susceptibility gene 101 (TSG101) and HSP90, but not the endoplasmic reticulum protein calnexin. These results indicate that HSPA1A may act as a chaperokine in the myometrium during pregnancy.Trials to improve oocyte developmental competence under metabolic stress by using antioxidants may start before or after oocyte maturation. In the present conceptual study, we aimed to identify the most efficient timing of antioxidant application in relation to a metabolic insult using a bovine invitro embryo production model. Pathophysiological concentrations of palmitic acid (PA) were used to induce metabolic stress during oocyte maturation or embryo development. Trolox (TR; antioxidant) treatment prior to, during or after the PA insult was tested to evaluate the protective, neutralising and rescuing capacity of TR respectively. Changes in embryo developmental competence, mitochondrial activity, reactive oxygen species (ROS) concentrations, blastocyst cell allocation and apoptosis and cell stress-related gene expression were monitored. The improvement in developmental capacity was most obvious when oocytes were preloaded with TR before the PA insult. This protective effect could be explained by the observed combination of increased mitochondrial activity with reduced ROS production. This resulted in blastocysts with normal cell counts and apoptosis, as well as increased nuclear factor erythroid 2-related factor 2 (NRF2) expression (a marker for redox regulatory processes) and normalised the expression of the mitochondrial transcription factor A (TFAM), a marker of mitochondrial biogenesis. These results indicate that 'pretreatment' of oocytes with antioxidants produces embryos that seem to be more resilient to a metabolic stress insult.In cattle, maternal recognition of early pregnancy depends on the effects of the embryonic signal interferon (IFN)-τ. IFN-stimulated genes have been upregulated in the maternal liver during early pregnancy. In this study, primary hepatocyte cell culture models were evaluated for their suitability to test Type I IFN effects invitro. The expression of target genes (interferon-stimulated gene 15 (ISG-15), interferon-induced GTP-binding protein (MX-1), C-X-C motif chemokine 10 (CXCL-10), CXCL-5, insulin-like growth factor 1 (IGF-1), IGF binding protein 2 (IGFBP-2)) was measured using reverse transcription-quantitative polymerase chain reaction in hepatocytes from monoculture or in indirect coculture with Kupffer cells (HKCid) on Days 1, 2, 3 and 4 of culture (n=21 donor cows). Gene expression was also measured on Day 4 after challenging the cultures with recombinant IFNτ, IFNα, progesterone (P4), IFNτ+IFNα or IFNτ+P4 for 6h. A significant increase in the mRNA expression of target genes in hepatocytes was shown in response to stimulation with IFNτ.
