Objective: To understand the homology of sequence type 562 (ST562) strains of Burkholderia pseudomallei which circulated in two separate continents (Asia and Australia) at different times. Methods:SpeⅠrestriction fragments and 4-locus multiple locus variable number tandem repeat analysis (MLVA-4) profiles were extracted from MSHR5858 (ST562 Australia strain) and 350105 (ST562 historical strain of Hainan) genomes respectively by in silico analysis and then compared with the PFGE and MLVA-4 results of five ST562 clinical isolates from Hainan to test their homology...

Objective: A limited understanding exists of the relationship between disability and older persons' living arrangements in low and middle-income countries (LMICs). We examine the associations between living arrangements, disability, and gender for individuals older than 50 years in rural South Africa. Method: Using the Study on global AGEing and adult health (SAGE) survey and Agincourt Health and socio-Demographic Surveillance System (HDSS) data, we explore older persons' self-reported disability by living arrangements and gender, paying particular attention to various multigenerational arrangements...

Alternative pre-mRNA splicing (AS) produces multiple isoforms of mRNAs and proteins from a single gene. It is most prevalent in the mammalian brain and is thought to contribute to the formation and/or maintenance of functional complexity of the brain. Increasing evidence has documented the significant changes of AS between different regions or different developmental stages of the brain, however, the dynamics of AS and the possible function of it during neural progenitor cell (NPC) differentiation is less well known...

Rabies is an important zoonotic disease distributed worldwide. A key question in rabies epidemiology is the identification of factors that impact virus dispersion. Here we apply new analytical methods, based on phylogeographic reconstructions of viral lineage movement, to undertake a comparative evolutionary-epidemiological study of the spatial dynamics of rabies virus (RABV) epidemics in different hosts and habitats. We have compiled RABV data sets from skunk, raccoon, bat and domestic dog populations in order to investigate the viral diffusivity of different RABV epidemics, and detect and compare those environmental factors that impact the velocity of viral spread in continuous spatial landscapes...

A long and winding road led to the discovery of immunoglobulin E (IgE) in 1966 and 1967. We are currently on a long and winding road to understand the immunologic basis of the clinical effects of the anti-IgE antibody omalizumab in asthma. It is possible that patients with asthma (as patients with chronic spontaneous urticaria) benefit in different immunologic ways from omalizumab treatment. This article reviews the history of IgE discovery and current concepts of anti-IgE therapy in asthma.

Smog pollution is a serious public health issue in urban China, where it is associated with public health through a range of respiratory and cardiovascular illnesses. Despite the negative health impacts of smog pollution, individual adaptive behaviors are poorly understood. This knowledge gap hinders the development of effective public policy to support and encourage the adoption of individual adaptive and mitigating behaviors to smog pollution. A questionnaire survey of 1141 randomly sampled individuals in a typical PM2...

Plants are the source of a variety of secondary metabolites, which are often used in the anticancer activity. Discovering new anticancer drug from herbal source is more important in both biological and pharmacological activities. Hence, the objective of this study is to identify the anticancer agent in Callistemon citrinus (Curtis) Skeels (CC) for the treatment of cancer. Very recently we have reported an increased antioxidant activity in the ethanolic and methanolic extracts (EE and ME) of CC but significantly reduced activity (rather increased cytotoxicity), in the n-hexane extract (HE)...

BACKGROUND/AIM: Children born preterm are at risk of neonatal complications but the long-term consequences for everyday functioning is not well known. The study aimed to identify patterns of everyday functioning in preschool children born preterm and at term in relation to perinatal data, neonatal risk factors, behaviour, and socioeconomic status. Registry data and data from parent rated questionnaires were collected for 331 children. METHOD: A person-oriented approach with a cluster analysis was used...

BACKGROUND: Tobacco use is often initiated during adolescence and continued into adulthood despite desires to quit. A better understanding of the neural correlates of abstinence from smoking in adolescents may inform more effective smoking cessation interventions. Neural reward systems are implicated in tobacco use disorder, and adolescent smokers have shown reduced reward-related ventral striatal activation related to increased smoking. METHODS: The current study evaluated nondrug reward anticipation in adolescent smokers using a monetary incentive delay task in fMRI pre- and post- smoking cessation treatment (n=14)...

Molecular weight (MW) distributions in source and treated water in Shanghai, China were investigated to understand the relationship between trihalomethanes formation potential/N-nitrosodimethylamine formation potential (THMFP/NDMAFP) and dissolved organic carbon (DOC) for different MW ranges (<1K, 1-10K, 10-30K, >30KDa). The result of MW distributions in source water indicated a relationship between THMFP/NDMAFP and DOC such that DOC for <1K and 1-30KDa DOC were linearly related to THMFP and NDMAFP, respectively...

Investigating the dependence of the catalysis on the size and structure of materials is of great significance for exploiting catalysts with characteristics of high activity, low cost, and new property. Non-precious metal catalysts bear high hope to meet the increasing demands of industrial applications in a cost-effective and environmentally friendly way. In this work, we take size-controlled BiOCl nanosheets as examples, which are synthesized via a hydrothermal method by changing the reaction conditions. The BiOCl nanosheets were characterized in details to understand their size-property relationships, and were found to exhibit a series of thickness-dependent physicochemical properties, including specific surface area, light absorption, and the separation efficiency of photo-generated charge carriers...

Diffuse agricultural runoff into rivers can result in contamination with herbicides for prolonged periods of time. Chronic exposure to herbicides has the potential to alter toxic impacts in primary producers such as benthic diatoms. Determining how individual diatom taxa respond to herbicide exposure over varied exposure durations is essential for assessing herbicide impacts. This study investigated the responses of various benthic diatom taxa and effects at the community level over 12days of atrazine exposure...

O(6)-Methylguanine (O(6)-MeG) is highly mutagenic and is commonly found in DNA exposed to methylating agents, generally leads to G:C to A:T mutagenesis. To study DNA replication encountering O(6)-MeG by the DNA polymerase (gp90) of P. aeruginosa phage PaP1, we analyzed steady-state and pre-steady-state kinetics of nucleotide incorporation opposite O(6)-MeG by gp90 exo(-). O(6)-MeG partially inhibited full-length extension by gp90 exo(-). O(6)-MeG greatly reduces dNTP incorporation efficiency, resulting in 67-fold preferential error-prone incorporation of dTTP than dCTP...
