'Sense of place' has become a central concept in the analysis of the cultural, personal and mental health risks posed by a changing climate. However, such place-related understandings of mental health and wellbeing remain largely limited to Indigenous health contexts. In this article we argue the relevance of sense of place in understanding the mental health impacts of climate change on family farmers who retain close living and working relationships to the land. We conducted a community-based qualitative case study located in the Western Australian Wheatbelt - a region that has experienced some of the most significant climate change in Australia...

PURPOSE: By 2006, women constituted 34% of academic medical faculty, reaching a critical mass. Theoretically, with critical mass, culture and policy supportive of gender equity should be evident. We explore whether having a critical mass of women transforms institutional culture and organizational change. METHODS: Career development program participants were interviewed to elucidate their experiences in academic health centers (AHCs). Focus group discussions were held with institutional leaders to explore their perceptions about contemporary challenges related to gender and leadership...

Wastewater-based epidemiology (WBE) employs the analysis of wastewater to detect and quantify drug use and discharge within a community. In this work, transformation products (TP) by microbes in the environment were identified after incubations in wastewater and an isolated microbial strain. The microbial strain was isolated from an enrichment culture of wastewater supplemented with 3,4-methylenedioxy-pyrovalerone, and identified by matrix assisted laser desorption - time of flight mass spectrometry as Pseudomonas putida (P...

AIMS: The aim of this work was to isolate novel lignin degrading organisms. METHODS AND RESULTS: Several pure cultures of bacteria that degrade lignin were isolated from bacterial consortia developed from decaying biomass. Among the isolates, Rhizobium sp. strain YS-1r (closest relative of Rhizobium petrolearium Strain SL-1) was explored for its lignin degrading ability. Microcosm studies showed that strain YS-1r was able to degrade a variety of lignin monomers, dimers, and also native lignin in switchgrass and alfalfa...

Post-war medical debates about the psychiatric consequences of married women's economic behaviour witnessed far more divergence and collision between perspectives than has often been acknowledged. Practitioners who approached women primarily as facilitators of family health-as wives and mothers-were mistrustful of the competing demands presented by paid employment. They were faced by a growing spectrum of opinion, however, which represented women as atrophying in the confines of domestic life, and which positioned work as a therapeutic act...

BACKGROUND Aberrant activation of Wnt/β-catenin has been shown to promote ovarian cancer proliferation and chemoresistance. Pyrvinium, an FDA-approved anthelmintic drug, has been identified as a potent Wnt inhibitor. Pyrvinium may sensitize ovarian cancer cells to chemotherapy. MATERIAL AND METHODS The effect of pyrvinium alone and its combination with paclitaxel in ovarian cancer was investigated using an in vitro culture system and in vivo xenograft models. The mechanisms of its action were also analyzed, focusing on the Wnt/β-catenin pathway...

Ghrelin and nesfatin-1 are two peptidyl hormones primarily involved in food intake regulation. We previously reported that the amount of dietary carbohydrates, protein and lipids modulates the expression of these peptides in goldfish in vivo. In the present work, we aimed to characterize the effects of single nutrients on ghrelin and nesfatin-1 in the intestine and hepatopancreas. First, immunolocalization of ghrelin and NUCB2/nesfatin-1 in goldfish hepatopancreas cells was studied by immunohistochemistry. Second, the effects of 2 and 4h-long exposures of cultured intestine and hepatopancreas sections to glucose, L-tryptophan, oleic acid, linolenic acid (LNA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on ghrelin and nesfatin-1 gene and protein expression were studied...

Fluid-phase endocytosis is a homeostatic process with an unknown role in tumor initiation. The driver mutation in pancreatic ductal adenocarcinoma (PDAC) is constitutively active KRas(G12D), which induces neoplastic transformation of acinar cells through acinar-to-ductal metaplasia (ADM). We have previously shown that KRas(G12D)-induced ADM is dependent on RAC1 and EGF receptor (EGFR) by a not fully clarified mechanism. Using three-dimensional mouse and human acinar tissue cultures and genetically engineered mouse models, we provide evidence that (i) KRas(G12D) leads to EGFR-dependent sustained fluid-phase endocytosis (FPE) during acinar metaplasia; (ii) variations in plasma membrane tension increase FPE and lead to ADM in vitro independently of EGFR; and (iii) that RAC1 regulates ADM formation partially through actin-dependent regulation of FPE...

The physical properties of the extracellular matrix play an essential role in guiding stem cell differentiation and tissue morphogenesis both in vivo and in vitro. Existing work to investigate the role of matrix mechanics in directing stem cell proliferation, self-renewal, and differentiation has been limited by the poor attachment and survival of human pluripotent cells cultured on soft matrices (Young's modulus E ≲ 1000 Pa). To address this limitation we developed a protocol for generating semi-interpenetrating networks of polyacrylamide and recombinant basement membrane...

BACKGROUND: Japanese encephalitis virus (JEV) is a neurotropic flavivirus causing mortality and morbidity in humans. Severe Japanese encephalitis cases display strong inflammatory responses in the central nervous system and an accumulation of viral particles in specific brain regions. Microglia cells are the unique brain-resident immune cell population with potent migratory functions and have been proposed to act as a viral reservoir for JEV. Animal models suggest that the targeting of microglia by JEV is partially responsible for inflammatory reactions in the brain...

: Wolbachia is an intracellular endosymbiont present in most arthropod and filarial nematode species. Transmission between hosts is primarily vertical, taking place exclusively through the female germline, though horizontal transmission has also been documented. Several studies indicate that Wolbachia is capable of transfer between somatic and germline cells during nematode development and in adult flies. However, the mechanisms underlying horizontal cell-to-cell transfer remain largely unexplored...

: Organohalide respiring bacteria can be difficult to enrich and isolate, which can limit research on these important organisms. The goal of this research was to develop a method to rapidly (minutes to days) enrich these organisms from a mixed community. The method presented is based on the hypothesis that organohalide respiring bacteria would be more hydrophobic than other bacteria as they dehalogenate hydrophobic compounds. The developed method tests this hypothesis by separating a portion of putative organohalide respiring bacteria, those phylogenetically related to Dehalococcoides mccartyi, at the interface between a hydrophobic organic solvent and aqueous media...

Chronic infections with hepatitis B and hepatitis C viruses (HBV and HCV) account for the majority of cases of cirrhosis and hepatocellular carcinoma. Current therapies for the infections have limitations and improved efficacy is necessary to prevent complications in carriers of the viruses. In the case of HBV persistence, the replication intermediate comprising covalently closed circular DNA (cccDNA) is particularly problematic. Licensed therapies have little effect on cccDNA and HBV replication relapses following treatment withdrawal...

In 2002, the Physician Charter on Medical Professionalism was published to provide physicians with guidance for decision making in a rapidly changing environment. Feedback from physicians indicated that they were unable to fully live up to the principles in the 2002 charter partly because of their employing or affiliated health care organizations. A multistakeholder group has developed a Charter on Professionalism for Health Care Organizations, which may provide more guidance than charters for individual disciplines, given the current structure of health care delivery systems...

Calcium phosphate-based (CaP) biomaterials are commonly used in bone reconstructive surgery to replace the damaged tissue, and can also serve as vectors for local drug delivery. Due to its inhibitory action on osteoclasts, the semi-metallic element gallium (Ga) is used for the systemic treatment of disorders associated with accelerated bone resorption. As it was demonstrated that Ga could be incorporated in the structure of CaP biomaterials, we investigated in the present work the biological properties of Ga-loaded CaP biomaterials...
