This study aimed to accessed the current status of the physical activity and the prevalence of comorbidity among the elderly (≥ 65 years old) in rural areas and to investigate the effect of physical activity intensity on hypertension-diabetes comorbidity in the elderly. A cross-sectional survey was conducted in Jia County, Pingdingshan, Henan Province from July 1 to August 31, 2023. A questionnaire was used to collect information on socio-demographic factors and chronic diseases, and the IPAQ (short form) to collect information about physical activity.

Sex-Specific Association between HO-1 (GT)n Promoter Polymorphism and Large-Artery Atherosclerosis Stroke.

Aims: Oxidative stress is a central factor in the pathogenesis of atherosclerosis and potentially exhibits sexual dimorphism. The induction of heme oxygenase-1 (HO-1) serves as a crucial mechanism against reactive oxygen species toxicity in the vascular wall, and this induction is regulated by the promoter (GT)n repeat length. We aim to investigate whether or not HO-1 gene (GT)n polymorphism is associated with the occurrence of large-artery atherosclerotic (LAA) stroke.

Inflammation May Mediate the Effects of Fluoride on Liver and Kidney Function of Adults: Cross-Sectional Studies in China.

To assess associations among fluoride exposure, the inflammation, and liver and kidney functions, a total of 1646 adults aged ≥ 18 years were recruited in cross-sectional studies conducted in 2017 and 2022 in fluorosis areas. Questionnaire surveys were administered to obtain the demographic information. Urine and blood samples were collected for determinations of urinary fluoride (UF), aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TBIL), blood urea nitrogen (BUN), serum creatinine (SCr), serum uric acid (SUA), and white blood cell (WBC) counts.

Brain Frailty on Neuroimaging Beyond Chronological Age Is Associated with Functional Outcome After Endovascular Thrombectomy in Patients with Anterior Large Vessel Occlusion.

Background: Current guidelines have not recommended an upper age limit for endovascular thrombectomy (EVT) in patients with large vessel occlusion (LVO) stroke. However, elder age links to an increased risk of poor outcome. This study aimed to investigate the efficacy of EVT in elderly versus non-elderly patients and determine the respective factors of poor outcome.

Resource Segmentation: A New Dimension of the Segmentation Hypothesis in Drought Adaptive Strategies and Its Links to Tree Growth Performance.

The segmentation hypothesis, a framework for understanding plant drought adaptive strategy, has long been based on hydraulic resistance and vulnerability. Storage of water and carbohydrate resources is another critical function and shapes plant drought adaption and fitness together with hydraulic efficiency and vulnerability. However, patterns and implications of the interdependency of stored water and carbohydrate resources in the context of the segmentation hypothesis are poorly understood.

β-cyclodextrin polymers as a new sorbent for solid-phase extraction of xenobiotics in Urine.

This study systematically assessed the performance of a newly developed solid-phase extraction (SPE) material, cellulose-supported aminated β-cyclodextrin polymer (amine-β-CDP@Cellulose), in determining 44 xenobiotics, encompassing endocrine-disrupting chemicals (EDCs), pharmaceuticals, and food additives in urine samples. The primary objective of the research was to synthesize a new sorbent, optimize the extraction protocol, and elucidate the underlying adsorption and desorption mechanisms. Following optimization, it was observed that amine-β-CDP@Cellulose achieved recoveries ranging from 80 % to 120 % for 28 of the 44 targeted xenobiotics, with only three compounds showing recoveries below 50 %.

Investigating the relationship between built environment and urban vitality using big data.

Urban vitality reflects the dynamic interaction between residents' activities and the urban environment, playing a pivotal role in fostering social and economic development. It enhances urban quality, competitiveness, and residents' well-being. Despite extensive scholarly attention, previous research has often overlooked the integration of big data and the spatial heterogeneity inherent in urban environments.

Relevance of peripheral inflammation indexes in different collateral circulation for intracranial hemorrhage in acute anterior circulation ischemic stroke patients undergoing endovascular treatment.

Background: Asymptomatic intracranial hemorrhage (aICH) is common after endovascular thrombectomy (EVT). Collateral circulation could modify the association between aICH with functional outcome and we aimed to investigate the impact of systemic inflammation index on 3-month outcome under different collateral circulation.

Method: Consecutive patients undertaken EVT were enrolled and classified into non-intracranial hemorrhage (non-ICH), aICH and symptomatic intracranial hemorrhage (sICH) groups according to the neurological status and National Institutes of Health Stroke Scale (NIHSS) changes within 72 hours after EVT.

Nurses' acceptance of nursing information systems: A multi-center cross-sectional study in China.

Background: In China, nursing information systems (NIS) implementation can face numerous barriers to acceptance, including the attitudes of potential users. However, few studies have evaluated this acceptance.

Objective: The aim of this study was to explain the acceptance of NIS utilizing a survey based on unified theory of acceptance and use of technology.

Increased global warming potential during freeze-thaw cycle is primarily due to the contribution of NO rather than CO.

While freeze-thaw cycle (FTC) can influence greenhouse gas emissions, the specific greenhouse gas that responds most strongly to FTC, as well as the underlying mechanisms, remain unclear. Here, we conducted a meta-analysis to explore the responses of global warming potential (GWP) and the fluxes of CO and NO to FTC. Our results showed that FTC treatment significantly increased GWP, NO flux, cumulative GWP, and cumulative NO emissions by 23.

Optimized liquid chromatography-tandem mass spectrometry protocol for enhanced detection of 45 pesticides in water and soil samples.

Rationale: The development of analytical screening techniques for pesticides is crucial for preventing and mitigating environmental contamination. Mass spectrometry-based screening methods differ based on the complexity of the sample matrix and the diversity of the target compounds. One of the major challenges is balancing cost reduction in the extraction process with the optimization of analytical results.

A trait-based root acquisition-defence-decomposition framework in angiosperm tree species.

To adapt to the complex belowground environment, plants make trade-offs between root resource acquisition and defence ability. This includes forming partnerships with different types of root associating microorganisms, such as arbuscular mycorrhizal and ectomycorrhizal fungi. These trade-offs, by mediating root chemistry, exert legacy effects on nutrient release during decomposition, which may, in turn, affect the ability of new roots to re-acquire resources, thereby generating a feedback loop.

Heme Oxygenase-1 Gene (GT)n Polymorphism Linked to Deep White Matter Hyperintensities, Not Periventricular Hyperintensities.

Background: Oxidative stress plays a principal role in the pathogenesis of white matter hyperintensities (WMHs). The induction of heme oxygenase-1 () gene in the brain represents 1 of the pivotal mechanisms to counteract the noxious effects of reactive oxygen species, and the transcriptional modulation of induction depends on the length of a GT-repeat (GT)n in the promoter region. We investigated whether the gene (GT)n polymorphism is associated with the risk of WMHs.

Excessive fluoride can adversely affect bone mineral density (BMD). Oxidative stress and mitochondrial dysfunction are crucial mechanisms of health damage induced by fluoride. Here, a cross-sectional survey involving 907 Chinese farmers (aged 18-60) was carried out in Tongxu County in 2017, aiming to investigate the significance of mitochondrial DNA copy number (mtDNAcn) and oxidative stress in fluoride-related BMD change.

Reactivity of unactivated peroxymonosulfate and peroxyacetic acid with thioether micropollutants: Mechanisms and rate prediction.

Thioether compounds, prevalent in pharmaceuticals, are of growing environmental concern due to their prevalence and potential toxicity. Peroxy chemicals, including peroxymonosulfate (PMS) and peroxyacetic acid (PAA), hold promise for selectively attacking specific thioether moieties. Still, it has been unclear how chemical structures affect the interactions between thioethers and peroxy chemicals.
