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...

Dietary partitioning often accompanies the increased morphological diversity seen during adaptive radiations within aquatic systems. While such niche partitioning would be expected in older radiations, it is unclear how significant morphological divergence occurs within a shorter time period. Here we show how differential growth in key elements of the feeding mechanism can bring about pronounced functional differences among closely related species. An incredibly young adaptive radiation of three Cyprinodon species residing within hypersaline lakes in San Salvador Island, Bahamas, has recently been described...

Sorghum bicolor is a drought tolerant C4 grass used for production of grain, forage, sugar, and lignocellulosic biomass and a genetic model for C4 grasses due to its relatively small genome (~800 Mbp), diploid genetics, diverse germplasm, and colinearity with other C4 grass genomes. In this study, deep sequencing, genetic linkage analysis, and transcriptome data were used to produce and annotate a high-quality reference genome sequence. Reference genome sequence order was improved, 29.6 Mbp of additional sequence was incorporated, the number of genes annotated increased 24% to 34,211, average gene length and N50 increased, and error frequency was reduced 10-fold to 1 per 100 kbp...

BACKGROUND: Quality of life (QOL) of patients in opioid substitution treatment (OST) is increasingly being addressed in research. However, no disease- or treatment-specific instrument is available to assess the QOL of this target population. The purpose of this project was to develop the first QOL instrument for OST patients. METHODS: Focus groups with 60 OST patients were analyzed using thematic analysis to elicit key QOL themes as perceived by patients. Identified themes were developed into items and refined through pilot testing and cognitive debriefing...

GII.4 noroviruses (NoVs) are a major cause of acute gastroenteritis in humans. A new variant of GII.4, the Sydney variant, has recently become more prevalent on a global scale. Intragenotype recombinations are widespread within the pandemic NoV GII.4 lineage, and are likely to be important forces driving the evolution and emergence of novel GII.4 viruses. In this study, we sought to examine the role that intergenotype recombination has played in the emergence of GII.4 Sydney 2012 variants. The results show that the GII...

BACKGROUND: Deep brain stimulation (DBS) of the subcallosal cingulate gyrus (SCG) is an experimental approach in treatment-resistant depression (TRD). Short-term results of efficacy in DBS are incongruent and studies investigating long-term effects are warranted. METHODS: We assessed efficacy of SCG-DBS in eight patients randomized into a delayed-onset group (sham-DBS four weeks) and a non-delayed-onset group. The primary outcome measure was improvement on the Hamilton Depression Rating-Scale (HAMD-24-item-version)...

In spite of the technological innovation in the biomedical science, cancer remains a critical disease. In this study, we designed a gallic acid/cadmium sulfide (GA/CdS) nanocomposite fabricated on the reduced graphene oxide (GA/CdS-rGO) nanosheets for the treatment system of human kidney cancer cells. The GA/CdS-rGO nanosheets have been prepared using gallic acid as a reducing agent. The characterization of nanocomposites was studied using UV-Vis spectroscope, FT-IR, XRD, SEM and TEM. The microscopic images showed the spherical shape and nano-scaled CdS nanoparticles on the sheet like rGO nanomaterials...

INTRODUCTION: Perceived epilepsy stigma and reduced social well-being are prevalent sources of distress in people with epilepsy (PWE). Yet, research on patient-level correlates of these difficulties is lacking, especially among underserved groups. MATERIALS AND METHODS: Racially/ethnically diverse adults with intractable seizures (N=60, 62% female; 79% Black, 20% Hispanic/Latino, 8% White) completed validated measures of personality (NEO Five Factor Inventory, NEO-FFI-3), perceived epilepsy stigma (Epilepsy Stigma Scale, ESS), and quality of life (Quality of Life Inventory in Epilepsy, QOLIE-89)...

OBJECTIVE: Epilepsy is a chronic disease with an increased risk of stigmatization due to psychosocial consequences of the seizures. Intuitively, one may well conclude that stigmatization would lead to depression in patients with epilepsy as well as in other patient groups with increased risk of stigmatization. Indeed, there are a few studies in support of this intuition. In this study, we aimed to investigate the relationship between level of stigmatization and the severity of the depressive symptoms in our patients with epilepsy...

Water availability and water demand are not evenly distributed in time and space. Many mega water diversion projects have been launched to alleviate water shortages in China. This paper analyzes the temporal and spatial features of 59 mega water diversion projects in China using statistical analysis. The relationship between nine major basins is measured using a network analysis method, and the associated economic, environmental and social impacts are explored using an impact analysis method. The study finds the development of water diversion has experienced four stages in China, from a starting period through to a period of high-speed development...

Dynamic spatial patterns such as traveling waves could theoretically encode spatial information, but little is known about whether or how they are employed by biological systems, especially higher eukaryotes. Here, we show that concentric target or spiral waves of active Cdc42 and the F-BAR protein FBP17 are invoked in adherent cells at the onset of mitosis. These waves predict the future sites of cell divisions and represent the earliest known spatial cues for furrow assembly. Unlike interphase waves, the frequencies and wavelengths of the mitotic waves display size-dependent scaling properties...

Anaerobic digestion (AD) of lignocellulosic biomass i.e. Napier grass (Pennisetum purpureum), was investigated via a series of batch and bench-scale experiments. Two semi-continuous bench-scale horizontal bioreactors were operated in parallel for nearly 300 days, and the reactors were able to handle the organic loading rate (OLR) up to 6 kg volatile solids (VS)/m(3)-d, which was among the highest OLR reported in the literature for lignocellulosic biomass. Hemicellulose was the main structural carbohydrate of lignocellulosic biomass per unit respective mass (dry weight) basis contributing to methane production...

BASC-2 SRP-A scores of 162 American Indian (AI) youth were compared with those of an ethnically diverse sample (N = 200) to explore group equivalence. A MANOVA indicated group differences among the five composites. AIs outscored non-Natives in Inattention/Hyperactivity. We examined AIs' ADHD scores in relation to their acculturation strategies, measured using the Bicultural Ethnic Identity Scale. Culturally marginalized AIs (low White and low Indian acculturation) reported stronger ADHD symptoms than bicultural, assimilated, or separated youth...

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...
