From August through December 2015, beachcast bird survey programs reported increased deposition of common murres ( Uria aalge) on central and northern California beaches, but not on southern California beaches. Coastal wildlife rehabilitation centers received more than 1,000 live, stranded, and debilitated murres from Sonoma County to San Luis Obispo County during August-October. Approximately two-thirds of admitted birds were after-hatch-year birds in emaciated body condition and in various stages of molt, with extremely worn plumage...

Introduction: Commercial divers, high altitude pilots, and astronauts are exposed to some inherent risk of decompression sickness (DCS), though the mechanisms that trigger are still unclear. It has been previously showed that diving may induce increased levels of serum angiotensin converting enzyme. The renin angiotensin aldosterone system (RAAS) is one of the most important regulators of blood pressure and fluid volume. The purpose of the present study was to control the influence of angiotensin II on the appearance of DCS...

BACKGROUND: The envelope protein of lentiviruses are type I transmembrane proteins, and their transmembrane domain contains conserved potentially charged residues. This highly unusual feature would be expected to cause endoplasmic reticulum (ER) localization. The aim of this study was to determine by which means the HIV-1 Env protein is transported to the cell surface although its transmembrane domain contains a conserved arginine residue. RESULTS: We expressed various chimeric proteins and analyzed the influence of their transmembrane domain on their intracellular localization...

BACKGROUND: Patients with lower extremity peripheral artery disease (PAD) are at increased risk of major adverse cardiovascular events (MACE) and major adverse limb events (MALE). There is limited information on the prognosis of patients who suffer MALE. OBJECTIVES: Among participants with lower extremity PAD, we investigated: 1) if hospitalizations, MACE, amputations, and deaths are higher after first episode of MALE compared with PAD patients who do not experience MALE and 2) the impact of treatment with low dose rivaroxaban and aspirin compared to aspirin alone on the incidence of MALE, peripheral vascular interventions, and all peripheral vascular outcomes over a median follow-up of 21 months...

Background: Responsible for 25% of all US cancer deaths, lung cancer presents complex care-delivery challenges. Adoption of the highly recommended multidisciplinary care model suffers from a dearth of good quality evidence. Leading up to a prospective comparative-effectiveness study of multidisciplinary vs. serial care, we studied the implementation of a rigorously benchmarked multidisciplinary lung cancer clinic. Methods: We used a mixed-methods approach to conduct a patient-centered, combined implementation and effectiveness study of a multidisciplinary model of lung cancer care...

Understanding the activation and internalization of G protein-coupled receptors (GPCRs) using conditional approaches is paramount to developing new therapeutic strategies. Here, we describe the design, synthesis, and testing of ExONatide , a benzylguanine-linked peptide agonist of the glucagon-like peptide-1 receptor (GLP-1R), a class B GPCR required for maintenance of glucose levels in humans. ExONatide covalently binds to SNAP-tagged GLP-1R-expressing cells, leading to prolonged cAMP generation, Ca2+ rises, and intracellular retention of the receptor...

Coproduction of research between consumers of mental health services and nonconsumer mental health researchers is increasing. There is some research available describing consumer perspectives of this experience. However, there is a notable lack of research on other (nonconsumer) researcher experiences of and views about consumer involvement in coproduced research. A qualitative exploratory study was undertaken to examine perspectives of mental health researchers about consumer involvement in research. In-depth individual interviews were undertaken with 11 nonconsumer mental health researchers in Australia and New Zealand...

Most cancers end up with the death of patients caused by the formation of secondary tumors, called metastases. However, how these secondary tumors appear and develop is only poorly understood. A fine understanding of the multiple steps of the metastasis cascade requires in vivo models allowing high spatiotemporal analysis of the behavior of metastatic cells. Zebrafish embryos combine several advantages such as transparency, small size, stereotyped anatomy, and easy handling, making it a very powerful model for cell and cancer biology, and in vivo imaging analysis...

Adult neurogenesis is the process by which neural stem cells give rise to new functional neurons in specific regions of the adult brain, a process that occurs throughout life. Significantly, neurodegenerative and psychiatric disorders present suppressed neurogenesis, activated microglia, and neuroinflammation. Traffic-related air pollution has been shown to adversely affect the central nervous system. As the cardinal effects of air pollution exposure are microglial activation, and ensuing oxidative stress and neuroinflammation, we investigated whether acute exposures to diesel exhaust (DE) would inhibit adult neurogenesis in mice...

BACKGROUND: The effect of menopausal hormone therapy (MHT)-previously known as hormone replacement therapy-on cardiovascular health remains unclear and controversial. This cross-sectional study examined the impact of MHT on left ventricular (LV) and left atrial (LA) structure and function, alterations in which are markers of subclinical cardiovascular disease, in a population-based cohort. METHODS: Post-menopausal women who had never used MHT and those who had used MHT ≥3 years participating in the UK Biobank who had undergone cardiovascular magnetic resonance (CMR) imaging and free of known cardiovascular disease were included...

Streptococcus pneumoniae is a leading cause of pneumonia and a significant economic burden. Antibiotic-resistant S. pneumoniae has become more prevalent in recent years and many pneumonia cases are caused by S. pneumoniae that is resistant to at least one antibiotic. The ubiquitin ligase natural killer lytic-associated molecule (NKLAM/RNF19b) plays a role in innate immunity and studies using NKLAM-knockout (NKLAM-KO) macrophages have demonstrated that NKLAM positively affects the transcriptional activity of STAT1...

The objective of this study was to assess the contribution of iodine intake from iodised household salt, iodised salt in instant noodles, and iodine in ground water in five regions of Indonesia. Secondary data analysis was performed using the 2013 Primary Health Research Survey, the 2014 Total Diet Study, and data from food industry research. Iodine intake was estimated among 2719 children, 10-12 years of age (SAC), 13,233 women of reproductive age (WRA), and 578 pregnant women (PW). Combined estimated iodine intake from the three stated sources met 78%, 70%, and 41% of iodine requirements for SAC, WRA and PW, respectively...

The number of people living with and beyond cancer is at an all time high. These survivors are not necessarily living well, as adverse side effects from cancer and its treatment can last up to 5 years and leave patients at a higher risk of developing secondary cancers and other chronic illnesses. Exercise has been proven to be a safe and effective method of intervention to decrease mortality and overall improve health outcomes. The biological mechanism through which this occurs is an area of research that is in its infancy and not well defined...

Ionic fluorophores are powerful tools for the study of environmental science and bio-imaging. However, traditional ionic dyes usually require long synthetic steps and suffer from aggregation-caused quenching effect. Here we report a water-soluble ionic aggregation-induced emission luminogen called DBTA, which is readily accessed by a novel one-step reaction. The switchable emission manipulated by hydrogen bonding provided solid evidence for the restriction of intramolecular motions as the mechanism of AIE phenomenon...
