G protein-coupled receptors (GPCRs) are the largest family of transmembrane signaling proteins. Within the gastrointestinal tract, GPCRs expressed by epithelial cells sense contents of the lumen, and GPCRs expressed by epithelial cells, myocytes, neurons, and immune cells participate in communication amongst cells. GPCRs control digestion, mediate digestive diseases, and coordinate repair and growth. GPCRs are the target of over one third of therapeutic drugs, including many drugs used to treat digestive diseases...

During αβ T cell development, T cell antigen receptor (TCR) engagement transduces biochemical signals through a protein-protein interaction (PPI) network that dictates dichotomous cell fate decisions. It remains unclear how signal specificity is communicated, instructing either positive selection to advance cell differentiation or death by negative selection. Early signal discrimination might occur by PPI signatures differing qualitatively (customized, unique PPI combinations for each signal), quantitatively (graded amounts of a single PPI series), or kinetically (speed of PPI pathway progression)...

Cast immobilization is a noninvasive and effective option in the treatment of fractures in children. However, its use can be associated with complications, such as pressure sores, skin infections, thermal injuries, and joint stiffness. In clinical practice, retained foreign objects in casts are not uncommon. This study aims to ascertain reasons for foreign objects being retained in casts and their effects on the skin. Eighteen children with retained foreign objects in their casts were identified and interviewed...

Outbreaks of infectious diseases can occur after natural disasters as vital services are disrupted and populations move into evacuation centres. National notifiable disease surveillance may be inadequate in these situations because of resource-consuming disease confirmation or system interruptions. Although syndromic surveillance has been used as an alternative in post-disaster situations, no systematic evaluations of it have been published. We evaluated the ad hoc paper-based syndromic surveillance system implemented in evacuation centres in Ibaraki prefecture after the 2011 Great East Japan Earthquake and Tsunami...

BACKGROUND: Childhood cancer survivors treated before 1992, when blood donor screening for hepatitis C virus (HCV) infection was introduced, are at risk of transfusion-transmitted HCV infection. A national HCV screening campaign targeting blood transfusion recipients was launched in Sweden in 2007-2010. The aims of this study were to, among adult childhood cancer survivors in Stockholm County, investigate the prevalence of HCV infection, the natural course of infection, treatment outcome and anti-HCV testing frequency before, during and after the screening campaign and finally to actively screen the untested ones...

Toxic Microcystis spp. blooms constitute a serious threat to water quality worldwide. Aeromonas veronii was isolated from Microcystis sp. colonies collected in Lake Kinneret. Spent Aeromonas media inhibits the growth of Microcystis aeruginosa MGK isolated from Lake Kinneret. The inhibition was much stronger when Aeromonas growth medium contained spent media from MGK suggesting that Aeromonas recognized its presence and produced secondary metabolites that inhibit Microcystis growth. Fractionations of the crude extract and analyses of the active fractions identified several secondary metabolites including lumichrome in Aeromonas media...

While amputation has traditionally been viewed as a failure of therapy, recent developments in amputation surgery and neural interfacing demonstrate improved functionality and bidirectional communication with prosthetic devices. The agonist antagonist myoneural interface (AMI) is one such bi-directional neural communication model comprised of two muscles, an agonist and an antagonist, surgically connected in series within the amputated residuum such that contraction of one muscle stretches the other. By preserving agonist-antagonist muscle dynamics, the AMI allows proprioceptive signals from mechanoreceptors within both muscles to be communicated to the central nervous system...

Natural contexts and family involvement are key features of effective intervention approaches. However, the measurement of community participation and parent engagement with children remains complex. Therefore, we examined the feasibility of combining use of the Language ENvironment Analysis (LENA® ) system and a global positioning system (GPS; i.e., Qstarz® BT-Q1000XT). The LENA is a small speech recognition device that captures and quantifies full-day recordings of the natural language environment. The Qstarz BT-Q1000XT is a wearable GPS data logger that allows identification of the locations a person visits...

This study examined the effects of psychoeducation and stress management techniques on Posttraumatic Stress Disorder (PTSD) symptoms in Libya. The 41 Libyan patients who volunteered to take part in the study were first assessed using the PTSD Checklist. They attended workshops on PTSD symptoms, stress management techniques, and communication skills on three successive days after which they were asked to answer the Coping Inventory for Stressful Situations two weeks after they completed the workshops. Among the 39% of the participants who were diagnosed with PTSD prior to the intervention, 15% met the diagnostic criteria for PTSD after the intervention...

Natural and man-made disasters carry with them major burden and very often the focus is on immediate survival and management of resulting infectious diseases. The impact of disasters directly and indirectly on the well-being and mental health of those affected often gets ignored. The reasons are often stigma and lack of attention to mental health consequences. In addition, often the focus is on preventing the spread of infectious diseases such as waterborne or airborne diseases. This is further complicated by the fact that often aid agencies in offering aid tend to focus on communicable diseases and not on mental health of populations...

Natural hazards are becoming increasingly expensive as climate change and development are exposing communities to greater risks. Preparation and recovery are critical for climate change resilience, and social media are being used more and more to communicate before, during, and after disasters. While there is a growing body of research aimed at understanding how people use social media surrounding disaster events, most existing work has focused on a single disaster case study. In the present study, we analyze five of the costliest disasters in the last decade in the United States (Hurricanes Irene and Sandy, two sets of tornado outbreaks, and flooding in Louisiana) through the lens of Twitter...

In the 21st century, public health is not only about fighting infectious diseases, but also contributing to a "multidimensional" well-being of people (health promotion, non-communicable diseases, the role of citizens and people in the health system etc.). Six themes of public health, issues of the 21st century will be addressed. Climate change is already aggravating already existing health risks, heat waves, natural disasters, recrudescence of infectious diseases. Big data is the collection and management of databases characterized by a large volume, a wide variety of data types from various sources and a high speed of generation...

Adults adjust the informativeness of their utterances to the needs of their addressee. For children, however, relevant evidence is mixed. In this article we explore the communicative circumstances under which children offer informative descriptions. In Experiment 1, 4- and 5-year-old children and adults described a target event from a pair of almost identical events to a passive confederate listener who could either see or not see the referents. Adults provided disambiguating information that picked out the target event but children massively failed to do so (even though 5-year-olds were more informative than 4-year-olds)...

Parks and protected areas can be ideal settings for climate change communication since many visitors have an affinity for natural and cultural settings, and an interest in resource protection. However, climate-based education efforts in the Midwestern United States may need a slightly different approach since this region lacks obvious indicators, such as sea level rise and melting glaciers. Interpretation, an informal communication process designed to transmit scientific information to visitors in leisure-based settings, could be a useful strategy for engaging visitors in climate change discussions...

BACKGROUND: Congenital coronary artery fistula in association with aneurysm of the involved coronary artery in adults is rare. Moreover, the right coronary artery- left atrial fistula is also uncommon. Most of the cases are asymptomatic. However, symptomatic patients need therapeutic interventions. The potential complications associated with this anomaly are life-threatening, therefore, there is a need to explore more on differential diagnosis, investigations, management strategies and prevention of complications...

Rare or orphan diseases often are inherited and overwhelmingly affect children. Many of these diseases have no treatments, are incurable, and have a devastating impact on patients and their families. Regulatory standards for drug approval for rare diseases must ensure that patients receive safe and efficacious treatments. However, regulatory bodies have shown flexibility in applying these standards to drug development in rare diseases, given the unique challenges that hinder efficient and effective traditional clinical trials, including low patient numbers, limited understanding of disease pathology and progression, variability in disease presentation, and a lack of established endpoints...
