G Kinman, S Wray
Background: There is growing evidence that presenteeism can be damaging for individuals and organizations. It is, therefore, important to identify the prevalence of working while sick in different working environments and the factors that contribute to such behaviour. Aims: To examine the prevalence of self-reported presenteeism in academic staff working in UK universities and colleges and the extent to which job demands, control, support and work engagement are risk factors...

Reproductive abnormalities are included as health complications in offspring exposed to poor prenatal nutrition. We have previously shown in a rodent model, that offspring born to nutrient restriction during pregnancy are born small, enter puberty early, and display characteristics of early ovarian aging as adults. The present study investigated whether key proteins involved in follicle recruitment and growth mediate ovarian follicle loss. Pregnant rats were randomized to: a standard diet throughout pregnancy and lactation (CON), or a calorie-restricted (50% of control) diet (UN) during pregnancy...

Natural experiments, such as longitudinal observational studies which follow-up residents as they relocate, provide a strong basis to infer causation between the neighborhood environment and health. This study examined whether changes in the level of neighborhood disadvantage were associated with changes in body mass index (BMI) following residential relocation. This analysis included data from 928 residents who relocated between 2007 and 2013, across four waves of the HABITAT study in Brisbane, Australia. Neighborhood disadvantage was measured using a census-derived composite index...

Cigarette smoking is the leading cause of preventable disease and death in the US. Cardiovascular co-morbidities associated with both active and secondhand cigarette smoking indicate the vascular toxicity of smoke exposure. Growing evidence supports the injurious effect of cigarette smoke on pulmonary endothelial cells and the roles of endothelial cell injury in development of Acute Respiratory Distress Syndrome (ARDS), emphysema, and pulmonary hypertension. This review summarizes results from studies of humans, preclinical animal models, and cultured endothelial cells that document toxicities of cigarette smoke exposure on pulmonary endothelial cell functions, including barrier dysfunction, endothelial activation and inflammation, apoptosis, and vasoactive mediator production...

BACKGROUND: Current immunisation levels in England currently fall slightly below the threshold recommended by the World Health Organization, and the three-year trend for vaccination uptake is downwards. Attitudes towards vaccination can affect future decisions on whether or not to vaccinate, and this can have significant public health implications. Interventions can impact future vaccination decisions, and these interventions can take several forms. Relatively little work has been reported on the use of vaccination interventions in young people, who form the next generation of individuals likely to make vaccination decisions...

A novel composite photocatalyst based on Cu₂ZnSnS₄ (CZTS) powders was synthesized and investigated for use as a photocatalyst. CZTS powders were first made using a conventional hydrothermal method and were then used to grow silver nanoparticles hybridized onto the CZTS under various conditions through a microwave-assisted hydrothermal process. After the obtained samples were subsequently mixed with 1T-2H MoS₂, the three synthesized component samples were characterized using X-ray diffractometry (XRD), scanning electron microscopy, transmission electron microscopy (FE-SEM, FE-TEM), UV-visible spectroscopy (UV-Vis), Brunauer-Emmet-Teller (BET), photoluminescence spectroscopy (PL), and X-ray photoelectron spectroscopy (XPS)...

The nutrient removal efficiency of Chlorella vulgaris cultivated in domestic wastewater was investigated, along with the potential to use membrane filtration as a pre-treatment tool during the wastewater treatment process. Chlorella vulgaris was batch cultivated for 12 days in a bubble column system with two different wastewater treatments. Maximum uptake of 94.18% ammonium (NH₄-N) and 97.69% ortho-phosphate (PO₄-P) occurred in 0.2 μm membrane filtered primary wastewater. Membrane filtration enhanced the nutrient uptake performance of C...

Biofilm formation is of growing concern in human and animal health. However, it is still unclear how biofilms are related to mastitis infections in dairy cattle. In this study, a comparison between two tests for biofilm formation and the association between biofilm and the presence of genes associated with biofilm formation were investigated for 92 Staphylococcus aureus isolates from clinical mastitis cases. Congo red agar (CRA) and microtitre test assay (MTA) in vitro phenotypic tests were used to evaluate biofilm formation...

Metal contaminated soils are increasing worldwide. Metal-tolerant plants growing on metalliferous soils are fascinating genetic and microbial resources. Seeds can vertically transmit endophytic microorganisms that can assist next generations to cope with environmental stresses, through yet poorly understood mechanisms. The aims of this study were to identify the core seed endophyte microbiome of the pioneer metallophyte Crotalaria pumila throughout three generations, and to better understand the plant colonisation of the seed endophyte Methylobacterium sp...

BACKGROUND: How hospital case-volume affects operative outcomes and cost continues to grow in importance. The purpose of this study is to examine the relationship of case volume with operative outcomes and cost in cleft palate repair. METHODS: Subjects undergoing cleft palate repair between 2004 and 2015 were identified in the Pediatric Health Information System (PHIS). Outcomes were compared between two exposure groups, those undergoing treatment at a high-volume institution (>85th percentile; >60 cases per year), and those undergoing treatment at a low-volume institution...

Team-based care in the outpatient women's health setting has the potential to help alleviate the demand for women's health care providers and to deliver improved quality of care to the growing population of US women. Although teamwork is necessary in the current health care system, most of the current obstetrics and gynecology and advanced practice provider (APP) workforce were not trained for collaborative practice. Core competencies for building an effective outpatient women's health care team are explained and current evidence regarding the specific role of APPs in women's health care is reviewed...

BACKGROUND AND PURPOSE: The Centers for Disease Control and Prevention estimated that there were 29 million falls and 7 million injuries in 2014 in the United States. Falls, decreased balance, and mobility disability are common in older adults and often result in loss of independence. Finding interventions to address these issues is important, as this age group is growing exponentially. Prior studies indicate balance and mobility can be improved by the balance-based torso-weighting (BBTW) assessment implemented through wear of a balance orthotic (BO)...

Diabetes is a metabolic syndrome increasing rapidly due to occupational stress, lack of physical activity, sedentary lifestyle and increasing occurrence of obesity, associated with rapidly growing urbanization and industrialization. Due to erroneous carbohydrate metabolism, diabetics are more prone to chronic complications like nephropathy, neuropathy, retinopathy, coronary artery disease and peripheral arterial disease resulting in tissue damage. Current treatment protocols to these problems produce more serious adverse effects and are costly too...

Few studies have critically evaluated how morphological variation within individual organisms corresponds to variation within and among species. Subindividual variation in plants facilitates such studies because their indeterminate modular growth generates multiple serially homologous structures along growing axes. Focusing on leaf form, we evaluate how subindividual trait variation relates to leaf evolution across Viburnum, a clade of woody angiosperms. In Viburnum we infer multiple independent origins of wide/lobed leaves with toothed margins from ancestors with elliptical, smooth-margined leaves...

Genetic and the essential oil composition variability among twelve Perovskia abrotanoides populations (PAbPs) growing wild in Iran were assessed by ISSR markers, GC-FID and GC-MS, respectively. Nine selected ISSR primers produced 119 discernible bands, of them 96 (80.7%) being polymorphic. Genetic similarity values among populations ranged between 0.07 and 0.79 which indicated a high level of genetic variation. Polymorphic information content, resolving power and marker index generated by ISSR primers were, 0...

When and where to move is a fundamental decision to migratory birds, and the fitness-related costs and benefits of migratory choices make them subject to strong selective forces. Site use and migration routes are outcomes of opportunities in the surrounding landscape, and the optimal migration strategy may be conservative or explorative depending on the variability of the environment occupied by the species. This study applies 25 years of resighting data to examine development in winter migration strategy of pink-footed geese divided among Denmark, the Netherlands and Belgium, and analyse potential drivers of strategy change as well as individuals' likelihood to break with migratory tradition...

Florence Volaire
Plant adaptation to drought has been extensively studied at many scales from ecology to molecular biology across a large range of model species. However, the conceptual frameworks underpinning the definition of plant strategies, and the terminology used across the different disciplines and scales are not analogous. 'Drought resistance' for instance refers to plant responses as different as the maintenance of growth and productivity in crops, to the survival and recovery in perennial woody or grassland species...

Increased life expectancy, due to the rise in life quality and the decline in mortality rates, is leading to a society in which the population aged 60 and over is growing more rapidly than the entire population. Although various models and model organisms have been employed to investigate the mechanism of aging, induced pluripotent stem cells (iPSCs) are useful candidates to study human aging and age-related human diseases. This work discusses how iPSCs can be used as an alternative to the model organisms such as yeast, Caenorhabditis elegans, Drosophila melanogaster, or the mouse...

Global warming is resulting in increased frequency of weather extremes. Root-associated fungi play important roles in terrestrial biogeochemical cycling processes, but the way in which they are affected by extreme weather is unclear. Here, we performed long-term field monitoring of the root-associated fungus community of a short rotation coppice willow plantation, and compared community dynamics before and after a once in 100 yr rainfall event that occurred in the UK in 2012. Monitoring of the root-associated fungi was performed over a 3-yr period by metabarcoding the fungal internal transcribed spacer (ITS) region...
