Static or quasi-static pressure-volume (P-V) curves can be used to determine the lung mechanical properties of patients suffering from acute respiratory distress syndrome (ARDS). According to the traditional interpretation, lung recruitment occurs mainly below the lower point of maximum curvature (LPMC) of the inflation P-V curve. Although some studies have questioned this assumption, setting of positive end-expiratory pressure 2 cmH2O above the LPMC was part of a "lung-protective" ventilation strategy successfully applied in several clinical trials...

Cadmium (Cd), a non-essential metal, stealthily enters the cells by utilizing the essential metal importing pathways. The zinc transporters Zip8, Zip14, and divalent metal transporter 1 (Dmt1) are now emerging as several important metal transporters involved in cellular Cd incorporation and their expressions have been shown to be down-regulated in several Cd-resistant (CdR) cell lines, however, the involvement of these transporters during the development of Cd-resistance in lung cells is unclear. In this study, we therefore check the expression of these metal transporters in our previously established rat lung epithelial cells (LECs) and show that the level of Zip8 is progressively silenced when LECs are adapted to increasing concentrations of CdCl2 (from 1 to 20 μM)...

Tumor genetic testing is standard of care for patients with advanced lung adenocarcinoma but the fraction of patients who derive clinical benefit remains undefined. Here, we report the experience of 860 patients with metastatic lung adenocarcinoma analyzed prospectively for mutations in >300 cancer-associated genes. Potentially actionable genetic events were stratified into one of four levels based upon published clinical or laboratory evidence that the mutation in question confers increased sensitivity to standard or investigational therapies...

The incretin hormones glucagon-like peptide (GLP)-1 and glucose-dependent insulinotropic polypeptide (GIP) are primarily known for their metabolic function in the periphery. GLP-1 and GIP are secreted by intestinal endocrine cells in response to ingested nutrients. Both GLP-1 and GIP stimulate the production and release of insulin from pancreatic β cells as well as exhibit several growth-regulating effects on peripheral tissues. GLP-1 and GIP are also present in the brain, where they provide modulatory and anti-apoptotic signals to neurons...

Exploring traditional medicines may lead to the development of low-cost and non-toxic cancer preventive agents. Si-Wu-Tang (SWT), comprising the combination of four herbs, Rehmanniae, Angelica, Chuanxiong, and Paeoniae, is one of the most popular traditional Chinese medicines for women's diseases. In our previous studies, the antioxidant Nrf2 pathways were strongly induced by SWT in vitro and in vivo. Since Nrf2 activation has been associated with anticarcinogenic effects, the purpose of this study is to evaluate SWT's activity of cancer prevention...

Background.: Primary care is an ideal setting for physical activity interventions to prevent and manage common long-term conditions. To identify those who can benefit from such interventions and to deliver tailored support, primary care professionals (e.g. GPs, practice nurses, physiotherapists, health care assistants) need reliable and valid tools to assess physical activity. However, there is uncertainty about the best-performing tool. Objective.: To identify the tools used in the literature to assess the physical activity in primary care and describe their psychometric properties...

A new batch, flow column electrocoagulation reactor (FCER) that utilises a perforated plate flow column as a mixer has been used to remove fluoride from drinking water. A comprehensive study has been carried out to assess its performance. The efficiency of fluoride removal (R%) as a function of key operational parameters such as initial pH, detention time (t), current density (CD), inter-electrode distance (ID) and initial concentration (C0) has been examined and an empirical model has been developed. A scanning electron microscopy (SEM) investigation of the influence of the EC process on morphology of the surface of the aluminium electrodes, showed the erosion caused by aluminium loss...

Over the last decades, several studies have reported emissions of nitrous oxide (N2 O) from microalgae cultures and aquatic ecosystems characterized by a high level of algal activity (e.g. eutrophic lakes). As N2 O is a potent greenhouse gas (GHG) and an ozone depleting pollutant, these findings suggest that large scale microalgae cultivation (and possibly, natural eutrophic ecosystems) could have significant environmental impacts. Using the model unicellular microalga Chlamydomonas reinhardtii, this study was conducted to investigate the molecular basis of microalgal N2 O synthesis...

Longitudinal Integrated Clerkships (LICs) are beginning to replace traditional short undergraduate rotations in general practice. LIC's differ from traditional rotations in that they are longer, they involve sustained relationships between students, patients and health professionals; and they integrate various strands of medical education. From early development in the US and Australia, LICs are now a fast-growing phenomenon across the world. We present three papers that seek to explain what LICs are, the evidence for their effectiveness and the practicalities of establishing or delivering a longitudinal integrated clerkship...

Psoriatic arthritis (PsA) is a chronic inflammatoryarthropathy that affects joints and entheses andis associated with psoriasis (PsO). There are fiveclinical patterns of PsA: symmetrical polyarthritis,distal interphalangeal arthropathy, asymmetricaloligoarthritis, arthritis mutilans, and spondylitis, withor without sacroiliitis. Concerning PsA, the goals oftherapy are to control inflammation, prevent articulardamage, and reduce discomfort in the affected joints.Although there are many therapeutic options forthe treatment of PsAs, physicians most often beginwith nonsteroidal anti-inflammatory drugs (NSAIDs)for mild disease...

Adverse childhood experiences are associated with an array of health, psychiatric, and behavioral problems including antisocial behavior. Criminologists have recently utilized adverse childhood experiences as an organizing research framework and shown that adverse childhood experiences are associated with delinquency, violence, and more chronic/severe criminal careers. However, much less is known about adverse childhood experiences vis-à-vis specific forms of crime and whether the effects vary across race and ethnicity...

Surgery for early-intermediate oropharyngeal squamous cell carcinoma (OPSCC) may involve using transoral endoscopic approaches or open surgical procedures. "Lateral pharyngotomy" (LP) is an open surgical approach that improves exposure of the oropharyngeal region, while avoiding mandibulotomy. The aim of the present study was to retrospectively analyze our experience with the surgical treatment of early-intermediate OPSCC using the LP approach, and to investigate the potentially prognostic clinical and/or pathological factors that might identify patients at higher risk of recurrence after primary surgery...

Sex-differences in pituitary growth hormone (GH) secretion (pulsatile in males vs near continuous/persistent in females) impart sex-dependent expression to hundreds of genes in adult mouse liver. STAT5, a GH-activated transcription factor that is essential for liver sexual dimorphism, is dynamically activated in direct response to each male plasma GH pulse. However, the impact of GH-induced STAT5 pulses on liver chromatin accessibility and downstream transcriptional events is unknown. Here, we investigate the impact of a single pulse of GH given to hypophysectomized mice on local liver chromatin accessibility [DNase hypersensitive site analysis], transcription rates [hnRNA analysis], and gene expression [quantitative PCR and RNA-Seq] determined 30, 90 or 240 min later...

OBJECTIVE: A recent meta-analysis suggested that opioid substitution therapy (OST) increased uptake of anti-retroviral treatment (ART) and HIV viral suppression. We modelled whether OST could improve the HIV prevention benefit achieved by ART amongst people who inject drugs (PWID). METHODS: We modelled how introducing OST could improve the coverage of ART across a PWID population for different baseline ART coverage levels. Using existing data on how yearly HIV-transmission risk is related to HIV plasma viral load, changes in the level of viral suppression across the population were used to project the relative reduction in yearly HIV-transmission risk achieved by ART, with or without OST, compared to if there was no ART - defined here as the prevention effectiveness of ART...
