This study utilized the Community Multi-scale Air Quality (CMAQ) model to simulate the spatial distribution of benzene, toluene, and xylene (BTX) concentrations in Ulsan metropolitan region (UMR), where large national industrial complexes (IC) are located. Through controlling the pollutant emissions in major IC, this study has performed a quantitative analysis on the influence of pollutant emissions from the IC on the BTX concentrations in surrounding urban areas. The seasonal modeling results indicated that the average BTX concentrations were high around the petrochemical complexes, with higher concentrations in the surrounding urban areas during the summer...

Measuring mental health accurately is an important endeavor for screening purposes. Depression scales, such as the Center for Epidemiologic Studies Depression (CES-D) scale, have been well-established among different populations. Yet, little work has been done to examine the reliability and validity of the CES-D among older American Indians and Alaska Natives. The purpose of our study was to examine the factor structure, reliability, and concurrent validity of the full 20-item and abbreviated 12-item CES-D scale with a sample of older American Indians...

Recent epidemiological data indicate that the popularity of electronic cigarettes (e-cigarettes), and consequently nicotine use, is rising in both adolescent and adult populations. As nicotine is a known developmental neurotoxin, these products present a potential threat for those exposed during early life stages. Despite this, few studies have evaluated the toxicity of e-cigarettes on the developing central nervous system (CNS). The goal of this study was to assess neurotoxicity resulting from early life exposure to electronic cigarette aerosols in an in vivo model...

BACKGROUND: Although significant progress has been made in reducing malaria transmission globally in recent years, a large number of people remain at risk and hence the gains made are fragile. Funding lags well behind amounts needed to protect all those at risk and ongoing contributions from major donors, such as the President's Malaria Initiative (PMI), are vital to maintain progress and pursue further reductions in burden. We use a mathematical modelling approach to estimate the impact of PMI investments to date in reducing malaria burden and to explore the potential negative impact on malaria burden should a proposed 44% reduction in PMI funding occur...

Bluetongue is a ruminant infectious disease that is characterized by hyperpyrexia, leukocyte decrease and mucosal ulcerative inflammation changes. In this study, three segments of Bluetongue virus (BTV)-8 VP2 protein (BTV-8A, 8B, and 8C) were cloned into pET-28a (+) and pMAl-c5X vectors and expressed in Escherichia coli BL21 (DE3) as histidine (His)-tagged (His-8A/8B/8C) and maltose-binding protein (MBP)-tagged (MBP-8A/8B/8C) fusion proteins. After purification, His-8A/8B/8C were used to immunize BALB/mice and MBP-8A/8B/8C were used to screen for monoclonal antibody (mAb)-secreting hybridomas...

BACKGROUND: Prior studies have suggested that, among the domains of depressive symptoms, low positive affect (PA) may have a distinct relationship with smoking cessation and relapse. However, the empirical basis for PA-focused interventions cessation is limited, with some mixed findings. OBJECTIVES: Using a large, diverse sample of treatment-seeking smokers, this study tested the hypothesis that PA adds unique predictive value beyond the effects of the other symptom domains in models of cessation and relapse...

Asthma is an aberrant inflammatory condition of the airways affecting approximately 1 in 10 children in affluent countries. An increasing body of evidence suggests that microbial exposures during a "critical window" of development in early life play a central role in determining future asthma susceptibility. However, like the disease itself, considerable heterogeneity exists among studies in which researchers have investigated the associations between particular microbial taxa and asthma immunology. As our understanding of asthmatic pathology evolves to enable clearer definition of asthma endotypes, it will be important to consider the impact of various environmental factors on each endotype...

As many as 70% to 97% of individuals with chronic kidney disease (CKD) report fatigue. Fatigue is one of the common, troubling symptoms that affects one's quality of life. This narrative review summarizes the evidence and gaps about the epidemiology, causative factors, and assessment of fatigue in individuals with CKD. Most studies are focused on the hemodialysis population, with very few focused on the peritoneal dialysis and transplant populations in which fatigue is also prevalent. Understanding fatigue and its correlates can help in assessing fatigue and in implementing interventions to alleviate fatigue...

Epidemiological studies conducted around the world have reported that the under-five mortality rate (U5MR) is closely associated with income and educational attainment. However, geographic elements should also remain a major concern in further improving child health issues, since they often play an important role in the survival environment. This study was undertaken to investigate the relationship between the U5MR, geographic, and socioeconomic factors, and to explore the associated spatial variance of the relationship in China using the geographically weighted regression (GWR) model...

BACKGROUND: Since 1975, childhood cancer incidence rates have gradually increased in the United States; however, few studies have conducted analyses across time to unpack this temporal rise. The aim of this study was to test the hypothesis that increasing cancer incidence rates are due to secular trends in pregnancy characteristics that are established risk factors for childhood cancer incidence including older maternal age, higher birthweight, and lower birth order. We also considered temporal trends in sociodemographic characteristics including race/ethnicity and poverty...
