PURPOSE: Low-dose non-enhanced computed tomography (LDCT) has been shown to provide low radiation exposure with proper diagnostic accuracy compared to standard dose non-enhanced computed tomography (SDCT) in patients with renal colic. The goal of our study is to estimate the accuracy of LDCT and SDCT interpretation by emergency medicine residents who primarily treated patients with renal colic. MATERIALS AND METHODS: Thirty sample images of both LDCT and SDCT from renal colic patients were extracted from January 2013 to December 2015 in a tertiary teaching hospital...

In theory, human diseases in which a specific cell type degenerates, such as neurodegenerative diseases, can be therapeutically addressed by replacement of the lost cells. The classical strategy for cell replacement is exogenous cell transplantation, but now, cell replacement can also be achieved with in situ reprogramming. Indeed, many of these disorders are age-dependent, and "rejuvenating" strategies based on cell epigenetic modifications are a possible approach to counteract disease progression. In this context, transient and/or partial reprogramming of adult somatic cells towards pluripotency can be a promising tool for neuroregeneration...

Researchers have consistently advocated positive associations between religion and well-being. The present research takes a step forward and explores potential mechanisms behind the same. The mediating role of a surprisingly neglected mechanism, positive virtues, specifically gratitude, forgiveness and altruism, is studied through a quantitative study on a sample of 220 adult respondents residing in Delhi NCR. The participants adhered to one of the six major religions present in India. Mediational analysis revealed that gratitude mediated the relationship between religiosity, spirituality and well-being via two pathways of forgiveness and altruism...

The aim of this study was to estimate the prevalence of binge drinking by regions in Spain and assess the effect of individual and contextual factors related to this drinking pattern in adolescents. A cross-sectional study was performed with data from the 2014 Spanish School Survey on Drug Use (ESTUDES) in students aged 14-18 years (N = 34,259). The outcome was binge drinking in adolescents during the last 30 days. Individual independent variables were socioeconomic variables and variables related to access to alcohol and its availability...

BACKGROUND: Medication use is high among nursing home (NH) residents, but there is a lack of longitudinal studies, determining medication use at admission and its evolution over time. AIM: Describing the evolution of the medication use two years after entering a NH, compared to the baseline observations and exploring the relation to the physical and mental health. METHODS: Data from the observational prospective Ageing@NH study, based on an inception cohort of newly admitted residents at NHs (65+) was used, selecting those consenting and with medication chart available...

Although young people in South Africa are growing up in an era where their socioeconomic circumstances are seemingly better than those of their parents' generation, they face greater risks in their trajectory to adulthood. This is mainly because the environment in which they are making sexual decisions is also rapidly evolving. Currently, South Africa has the highest prevalence of HIV and AIDS in the world among young people aged 15-24. This study examined the effect of sexual behaviours initiated in adolescence on enrolment in post-secondary education...

There has been a secular decline in age at menarche since the 19th century. Early-maturing women are more likely to have their sexual debut at a younger age, which in turn gives rise to a host of reproductive health and social problems. This study used data from five waves of National Demographic and Health Surveys conducted in the Philippines between 1993 and 2013 to examine the trends and socioeconomic differentials in age at menarche and sexual debut. The changing trend in age at menarche and sexual debut was examined across birth cohorts, and logistic regressions were used to identify the determinants of early sexual debut...

Nitric oxide (NO) is a therapeutic implicated for the treatment of diseases affecting lymphatic tissues, which range from infectious and cardiovascular diseases to cancer. Existing technologies available for NO therapy, however, provide poor bioactivity within lymphatic tissues. In this work, we address this technology gap with a NO encapsulation and delivery strategy leveraging the formation of S-nitrosothiols on lymphatic-targeting Pluronic-stabilized, poly(propylene sulfide)-core nanoparticles (SNO-NP). We evaluated in vivo the lymphatic versus systemic delivery of NO resulting from intradermal administration of SNO-NP benchmarked against a commonly used, commercially available small molecule S-nitrosothiol NO donor, examined signs of toxicity systemically as well as localized to the site of injection, and investigated SNO effects on lymphatic transport and NP uptake by LN-resident cells...

As pregnancy progresses the placental syncytiotrophoblast increasingly assumes control of maternal glucose homeostasis through the release and counter-balancing effects of placental lactogen (PL) and placental variant growth hormone (GH-V). While local actions of these hormones on placental growth and function are likely to exist, each also exerts indirect actions to ensure fetal nutritional availability through modulation of the maternal insulin/insulin-like growth factor axis. Peripheral insulin resistance results from the increasing levels of GH-V in the maternal circulation and is counter-balanced by an increase in insulin availability through an expansion of maternal pancreatic β-cell mass...

Atherosclerosis is considered a chronic inflammatory disease of the arterial wall. Recently, compelling evidence has arisen for the role of monocytes and neutrophils and a particular protein complex that resides within these cells - the NLRP3 inflammasome - in atherosclerosis-associated inflammation. It is now also known that cholesterol crystals are present through all stages of atherosclerosis and can activate the NLRP3 inflammasome within these inflammatory cells to produce interleukin 1β and interleukin 18 - key mediators in the inflammatory cascade that drive plaque progression and instability...

Invasive alien plants are likely to be released from specialist herbivores and at the same time encounter biotic resistance from resident generalist herbivores in their new ranges. The Shifting Defense Hypothesis predicts that this will result in evolution of decreased defense against specialist herbivores and increased defense against generalist herbivores. To test this, we performed a comprehensive meta-analysis of 61 common garden studies that provide data on resistance and/or tolerance for both introduced and native populations of 32 invasive plant species...

Homeless young adults are at risk for alcohol and other drug (AOD) use and risky sexual behavior. Interventions are needed to help these young people reduce their risky behavior, but this population is often difficult to engage and retain in services. We offered a four-session AOD and risky sex reduction program to 100 participants and examined if retention in the program was predicted by a number of factors: demographics, homelessness severity, other service use, AOD behaviors, mental health symptoms, sexual risk behaviors, and readiness to change AOD and condom use...

Latinos are the largest growing population and have the highest fertility rates in the US. In response, this study assessed if late initiation of or no prenatal care (PNC) mediated the relationship among adverse birth outcomes and interactions between immigrant and insurance status. This study used cross-sectional data (2002-2004) limited to 109,399 women of Mexican ethnicity who had singleton births in the San Joaquin Valley, California. We conducted hierarchical mediation analyses. US-born Mexican women who used private or public insurance for PNC were more likely to have infants born at low-birth weight and premature compared to Mexican first generation immigrant women...

Studies point to a relationship between fantasy sports/daily fantasy sports (DFS) play and gambling behavior. However, little is known about the nature of those relationships, particularly regarding the development of gambling problems. This study investigates the nature, frequency, and preferences of gambling behavior as well as problem gambling severity and comorbid conditions among DFS players. Data were collected from an epidemiologic survey of 3634 New Jersey residents on gambling and leisure activities...

In order to multiply and cause disease a virus must transport its genome from outside the cell into the cytosol, most commonly achieved through the endocytic network. Endosomes transport virus particles to specific cellular destinations and viruses exploit the changing environment of maturing endocytic vesicles as triggers to mediate genome release. Previously we demonstrated that several bunyaviruses, which comprise the largest family of negative sense RNA viruses, require the activity of cellular potassium (K+) channels to cause productive infection...

Histones H1 or linker histones are highly dynamic proteins that diffuse throughout the cell nucleus and associate with chromatin (DNA and associated proteins). This binding interaction of histone H1 with the chromatin is thought to regulate chromatin organization and DNA accessibility to transcription factors and has been proven to involve a kinetic process characterized by a population that associates weakly with chromatin and rapidly dissociates and another population that resides at a binding site for up to several minutes before dissociating...

Cadmium (Cd) is a heavy metal that has no known biological function and is toxic for many living organisms. The maximum level of Cd concentration allowed in the international market for wheat grain is 0.2 mg kg-1. Because phenotyping for Cd uptake is expensive and time consuming, molecular markers associated with genes conferring low Cd uptake would expedite selection and lead to the development of durum cultivars with reduced Cd concentrations. Here, we identified single nucleotide polymorphisms (SNPs) associated with a novel low Cd uptake locus in the durum experimental line D041735, which has hexaploid common wheat in its pedigree...

Alcohol dependence and alcoholic liver disease represent a major public health problem with substantial morbidity and mortality. By yet incompletely understood mechanisms, chronic alcohol abuse is associated with increased intestinal permeability and alterations of the gut microbiota composition, allowing bacterial components, bacteria, and metabolites to reach the portal and the systemic circulation. These gut-derived bacterial products are recognized by immune cells circulating in the blood or residing in remote organs such as the liver leading to the release of pro-inflammatory cytokines which are considered important mediators of the liver-gut-brain communication...

Background -Patients with systemic sclerosis-associated pulmonary arterial hypertension (SSc-PAH) have a far worse prognosis than those with idiopathic PAH (IPAH). In the intact heart, SSc-PAH exhibits depressed rest and reserve right ventricular (RV) contractility as compared to IPAH. We tested whether this disparity involves underlying differences in myofilament function. Methods -Cardiac myocytes were isolated from RV septal endomyocardial biopsies from patients with SSc-PAH, IPAH, or SSc with exertional dyspnea but no resting PAH (SSc-d); control RV septal tissue was obtained from non-diseased donor hearts (6-7/group)...

Corticotropin-releasing factor (CRF) neurons in the Paraventricular Nucleus of the Hypothalamus (PVN) initiate Hypothalamic-Pituitary-Adrenal (HPA) axis activity through release of CRF into the portal system as part of a coordinated neuroendocrine, autonomic, and behavioral response to stress. Recent discovery of neurons expressing CRF receptor type 1 (CRFR1), the primary receptor for CRF, adjacent to CRF neurons within the PVN, suggest that CRF also signals within the hypothalamus to coordinate aspects of the stress response...
