Tin contamination in sediments of Lake Zurich: source, spread, history and risk assessment.

Unlabelled: Industrial activities of a silk dyeing factory in Thalwil, on the shore of Lake Zurich, Switzerland, caused extreme Sn contamination of lake sediments. In this study, we determine the contamination source, spread, and age using a multiproxy approach. We used X-ray fluorescence spectroscopy (XRF) core scanning and further geochemical analyses to assess the contamination spreading and thickness in the sedimentary column.

Interactive effects of rhizospheric soil microbes and litter on the growth of the invasive hyperaccumulator in cadmium-contaminated soil.

Both rhizospheric soil microbes and shoot litter input can have profound effects on plant performance; however, their interactive effects on plants in Cd-contaminated soils remain poorly understood. We grew an invasive hyperaccumulator, , in sterilized and unsterilized rhizosphere soil without litter or with a low (0.2%, dry weight ratio) or a high amount (1%) of litter from in soil with low (5 mg kg) or high (10 mg kg) concentrations of Cd.

Design: Retrospective cohort study.

Participants: Adult patients undergoing phacoemulsification at 8 United Kingdom National Health Service clinical centers between July 2003 and March 2015.

Pathology Findings and In-Life Correlates in the Nonclinical Development of Adeno-Associated Virus (AAV)-Based Retinal Gene Therapies.

Adeno-associated virus (AAV)-based vectors are the most frequently used platform for retinal gene therapy. Initially explored for the treatment of loss-of-function mutations underpinning many inherited retinal diseases, AAV-based ocular gene therapies are increasingly used to transduce endogenous cells to produce therapeutic proteins, thus producing site-specific biofactories. Relatively invasive ocular routes of administration (ROA) mean prominent procedure-related in-life, and histopathological findings may be observed with some regularity.

Can We Use Genomic Data to Predict Maladaptation to Environmental Change?

Climate change is happening fast, maybe too fast for some species and populations to adapt in time. Therefore, practice and science are highly interested in predicting how populations may react to future changes. Such information could be used to identify populations at risk or sources for assisted gene flow.

WATCH: A Workflow to Assess Treatment Effect Heterogeneity in Drug Development for Clinical Trial Sponsors.

This article proposes a Workflow for Assessing Treatment effeCt Heterogeneity (WATCH) in clinical drug development targeted at clinical trial sponsors. WATCH is designed to address the challenges of investigating treatment effect heterogeneity (TEH) in randomized clinical trials, where sample size and multiplicity limit the reliability of findings. The proposed workflow includes four steps: analysis planning, initial data analysis and analysis dataset creation, TEH exploration, and multidisciplinary assessment.

Objective: This qualitative study aimed to explore patients' experiences with a novel treatment approach for endometriosis-associated pain, termed 'sinosomatics'. Specifically, it sought to understand women's experiences of the treatment and its components, the effects of the treatment on biological, psychological, and social levels, and how the women interpreted the changes they experienced.

Methods: We conducted ten semi-structured interviews with patients, who had undergone the complementary treatment for endometriosis-associated pain.

Impact of dementia and mild cognitive impairment on bone health in older people.

Mild cognitive impairment, dementia and osteoporosis are common diseases of ageing and, with the increasingly ageing global population, are increasing in prevalence. These conditions are closely associated, with shared risk factors, common underlying biological mechanisms and potential direct causal pathways. In this review, the epidemiological and mechanistic links between mild cognitive impairment, dementia and skeletal health are explored.

Centenarians-the way to healthy vascular ageing and longevity: a review from VascAgeNet.

The prevalence of centenarians, people who lived 100 years and longer, is steadily growing in the last decades. This exceptional longevity is based on multifaceted processes influenced by a combination of intrinsic and extrinsic factors such as sex, (epi-)genetic factors, gut microbiota, cellular metabolism, exposure to oxidative stress, immune status, cardiovascular risk factors, environmental factors, and lifestyle behavior. Epidemiologically, the incidence rate of cardiovascular diseases is reduced in healthy centenarians along with late onset of age-related diseases compared with the general aged population.

The Topology of Poly(2-methyl-2-oxazine) Shells on Nanoparticles Determines Their Interaction with Serum and Uptake by Immune Cells.

Cyclic poly(2-methyl-2-oxazine) (-PMOZI) brush shells on Au nanoparticles (NPs) exhibit enhanced stealth properties toward serum and different cell lines compared to their linear PMOZI (-PMOZI) counterparts. While selectively recruiting immunoglobulins, -PMOZI shells reduce overall human serum (HS) protein binding and alter the processing of complement factor 3 (C3) compared to chemically identical linear shells. Polymer cyclization significantly decreases NP uptake by nonphagocytic cells and macrophages in both complement-deficient fetal bovine serum (FBS) and complement-expressing HS, indicating ineffective functional opsonization.

Feed additives for methane mitigation: Modeling the impact of feed additives on enteric methane emission of ruminants-Approaches and recommendations.

Over the past decade, there has been considerable attention on mitigating enteric methane (CH) emissions from ruminants through the utilization of antimethanogenic feed additives (AMFA). Administered in small quantities, these additives demonstrate potential for substantial reductions of methanogenesis. Mathematical models play a crucial role in comprehending and predicting the quantitative impact of AMFA on enteric CH emissions across diverse diets and production systems.

Impact of maternal antenatal nutrition and infection treatment interventions on Longitudinal Infant Development and Growth in rural Ethiopia: protocol of the LIDG child follow-up study.

Introduction: Maternal undernutrition and inflammation in utero may significantly impact the neurodevelopmental potential of offspring. However, few studies have investigated the effects of pregnancy interventions on long-term child growth and development. This study will examine the effects of prenatal nutrition and infection management interventions on long-term growth and neurodevelopmental outcomes of offspring.

Paediatric Personalized Research Network Switzerland (SwissPedHealth): a joint paediatric national data stream.

Introduction: Children represent a large and vulnerable patient group. However, the evidence base for most paediatric diagnostic and therapeutic procedures remains limited or is often inferred from adults. There is an urgency to improve paediatric healthcare provision based on real-world evidence generation.

Derivation and validation of the simplified BleedingAudit Triage Trauma (sBATT) score: a simplified trauma score for major trauma patients injured in motor vehicle collisions.

Objectives: To develop and validate a simplified Bleeding Audit Triage Trauma (sBATT) score for use by lay persons, or in areas and environments where physiological monitoring equipment may be unavailable or inappropriate.

Design: The sBATT was derived from the original BATT, which included prehospital systolic blood pressure (SBP), heart rate, respiratory rate, Glasgow Coma Scale (GCS), age and trauma mechanism. Variables suitable for lay interpretation without monitoring equipment were included (age, level of consciousness, absence of radial pulse, tachycardia and trapped status).

A new filamentous phototrophic bacterium Khr17 was isolated as an enrichment culture from the brackish polar lake Bol'shie Khruslomeny. The organism was a halotolerant, strictly anaerobic phototroph possessing photosystem II. Sulfide was required for phototrophic growth.

An overview of climate changes and its effects on health - from mechanisms to One Health.

Human activities, primarily the burning of fossil fuels, widespread deforestation, soil erosion or machine-intensive farming methods, manufacturing, food processing, mining, and construction iron, cement, steel, and chemicals industry, have been the main drivers of the observed increase in Earth's average surface temperature and climate change. Rising global temperatures, extreme weather events, ecosystems disruption, agricultural impacts, water scarcity, problems in access to good quality water, food and housing, and profound environmental disruptions such as biodiversity loss and extreme pollution are expected to steeply increase the prevalence and severity of acute and chronic diseases. Its long-term effects cannot be adequately predicted or mitigated without a comprehensive understanding of the adaptive ecosystems.

Human T9 cells rely on PPAR-γ-mediated cystine uptake to prevent lipid peroxidation and bioenergetic failure.

T9 cells are implicated in allergic skin inflammation and depend on the transcription factor PPAR-γ for full effector function. In this study, we uncovered a role for PPAR-γ in the amino acid metabolism of human T9 cells. In in-vitro-primed T9 cells, PPAR-γ expression positively correlated with the expression of SLC7A8, which encodes LAT2, a transporter of large neutral amino acids, including cystine.

Subchondral bone marrow adipose tissue lipolysis regulates bone formation in hand osteoarthritis.

Objective: Bone marrow adipose tissue (BMAT) is emerging as an important regulator of bone formation and energy metabolism. Lipolysis of BMAT releases glycerol and fatty acid substrates that are catabolized by osteoblasts. Here, we investigated whether BMAT lipolysis is involved in subchondral bone formation in hand osteoarthritis (OA).
