Avian Influenza virus (AIV) is a major concern for the global poultry industry. Since 2012, several countries have reported AIV outbreaks among domestic poultry. These outbreaks had tremendous impact on poultry production and socio-economic repercussion on farmers. In addition, the constant emergence of highly pathogenic AIV also poses a significant risk to human health. In this study, we used a chicken lung epithelial cell line (CLEC213) to gain a better understanding of the molecular consequences of low pathogenic AIV infection in their natural host...

Microplastics (<5 mm) are contaminants of emerging global concern. They have received considerable attention in scientific research, resulting in an increased awareness of the issue among politicians and the general public. However, there has been significant variation in sampling and extraction procedures used to quantify microplastics levels. The difference in extraction procedures can especially impact study outcomes, making it difficult, and sometimes impossible, to directly compare results among studies...

Emerging evidence has suggested that cytoreductive prostatectomy (CRP) allows superior oncologic control when compared to current standard of care androgen deprivation therapy alone. However, the safety and benefit of cytoreduction in metastatic prostate cancer (mPCa) has not been proven. Therefore, we evaluated the incidence of complications following CRP in men newly diagnosed with mPCa. A total of 68 patients who underwent CRP from 2006 to 2014 at four tertiary surgical centers were compared to 598 men who underwent radical prostatectomy for clinically localized prostate cancer (PCa)...

Histone modifications and histone variants barcode the genome and play major roles in epigenetic regulations. Chromatin immunoprecipitation (ChIP) coupled with next-generation sequencing (NGS) is a well-established method to investigate the landscape of epigenetic marks at a genomic level. Here, we describe procedures for conducting ChIP, subsequent NGS library construction, and data analysis on histone modifications and histone variants in Arabidopsis thaliana. We also describe an optimized nuclear isolation procedure to prepare chromatin for ChIP in the liverwort, Marchantia polymorpha, which is the emerging model plant ideal for evolutionary studies...

Despite well-documented benefits of colorectal cancer (CRC) screening, African Americans are less likely to be screened and have higher CRC incidence and mortality than Whites. Emerging evidence suggests medical mistrust may influence CRC screening disparities among African Americans. The goal of this systematic review was to summarize evidence investigating associations between medical mistrust and CRC screening among African Americans, and variations in these associations by gender, CRC screening type, and level of mistrust...

Staphylococcus aureus is a major cause of skin and soft-tissue infection. The bacterium expresses four major proteases emerging as virulence factors; aureolysin (Aur), V8 protease (SspA), staphopain A (ScpA), and staphopain B (SspB). We hypothesized that human galectin-3, a β-galactoside-binding lectin involved in immune regulation and antimicrobial defense, is a target for these proteases, and that proteolysis of galectin-3 is a novel immune evasion mechanism. Indeed, supernatants from laboratory strains and clinical isolates of S...

The emergence of pan-resistant Klebsiella pneumoniae strains is an increasing concern. In the current study we describe a cluster of 9 pan-resistant K. pneumoniae ST147 isolates encountered in 4 patients over nearly one year in 3 hospitals of the United Arab Emirates. The isolates exhibited highly similar genotypes. All produced chromosomally encoded OXA-181 and the majority also produced the NDM-5 carbapenemase. Similarly to the previously described single isolate from the UAE, MS6671, the mgrB was disrupted by a functional, ISEcp1-driven blaOXA-181 insertion causing resistance to carbapenems...

Biodiversity is of critical value to human societies, but recent evidence that biodiversity may mitigate infectious-disease risk has sparked controversy among researchers. The majority of work on this topic has focused on direct assessments of the relationship between biodiversity and endemic-pathogen prevalence, without disentangling intervening mechanisms; thus study outcomes often differ, fuelling more debate. Here, we suggest two critical changes to the approach researchers take to understanding relationships between infectious disease, both endemic and emerging, and biodiversity that may help clarify sources of controversy...

Landscape change and altered host abundance are major drivers of zoonotic pathogen emergence. Conservation and biodiversity management of landscapes and vertebrate communities can have secondary effects on vector-borne pathogen transmission that are important to assess. Here we review the potential implications of these activities on the risk of Lyme borreliosis in the United Kingdom. Conservation management activities include woodland expansion, management and restoration, deer management, urban greening and the release and culling of non-native species...

Sleep is a universal physiological state evolutionarily conserved among species, but the molecular basis for its regulation is still largely unknown. Due to its electroencephalogram criteria, sleep has long been investigated and described mostly in mammalian species. The fruit fly, Drosophila melanogaster, has emerged as a genetic model organism for studying sleep. The Drosophila sleep is behaviorally defined, and is tightly regulated by circadian and homeostatic processes, like mammals. Genetic analyses using Drosophila have successfully identified a number of conserved regulatory mechanisms underlying sleep between flies and mammals...

BACKGROUND: Injuries contribute to a substantial proportion of the burden of disease in Kenya. Trauma registries can be a very useful source of data to understand patterns of injuries and serve to provide information about potential improvements in the care of injured patients. In Kenya, health facility-based injury data has been largely administrative. Our aim was to develop and implement a prospective trauma registry at the largest trauma hospital in Kenya, the Kenyatta National Hospital, and to understand the nature of injuries presenting to the hospital, their treatment and care, and their outcomes...

BACKGROUND: Anaplasma phagocytophilum is an emerging tick-borne zoonotic pathogen of increased interest worldwide which has been detected in northern Africa. Anaplasma platys is also present in this region and could possibly have a zoonotic potential. However, only one recent article reports on the human esposure to A. phagocytophilum in Morocco and no data are available on canine exposure to both bacteria. Therefore, we conducted a cross-sectional epidemiological study aiming to assess both canine and human exposure to Anaplasma spp...
