Novel binary regulated silicon-carbon materials as high-performance anodes for lithium-ion batteries.

The massive volume dilation, unsteady solid electrolyte interphase, and weak conductivity about Si have failed to bring it to practical applications, although its potential capacity is up to 4200 mAh g. For solving these problems, novel binary regulated silicon-carbon materials (Si/BPC) were done by a sol-gel procedure combined with single carbonization. Analytical techniques were systematically utilized to examine the effects of element doping at several gradients on morphology, structure and electrochemical properties of composites, thus the optimal content was identified.

Chemogenetic activation of astrocytic Gi signaling promotes spinogenesis and motor functional recovery after stroke.

Ischemic stroke is the leading cause of adult disability. The rewiring of surviving neurons is the fundamental process for functional recovery. Accumulating evidence implicates astrocytes in synapses and neural circuits formation, but few studies have further studied how to enhance the effects of astrocytes on synapse and circuits after stroke and its impacts on post-stroke functional recovery.

The relationship between self-assessment living standard and mental health among the older in rural China: the mediating role of sleep quality.

Background And Objective: Mental health imbalance are the main cause of anxiety, depression and happiness reduction in the older. Self-assessment living standard and sleep quality are both influencing factors of mental health. Meantime, self-assessment living standard has an impact on sleep quality.

Gender specific cut-off points of age for disability among rural elderly in Anhui Province, China.

Objective: The purpose of this study was to determine the optimal cut-off values of age for disability in order to predict the risk of disability for older adults in rural areas.

Methods: WHO Disability Assessment Schedule 2.0 was used to assess disability.

Dietary therapy in abdominal aortic aneurysm - Insights from clinical and experimental studies.

Abdominal aortic aneurysm (AAA) is a prevalent vascular disease with high mortality rates upon rupture. Despite its prevalence in elderly populations, there remain limited treatment options; invasive surgical repair, while risky, is the only therapeutic intervention with proven clinical benefits. Dietary factors have long been suggested to be closely associated with AAA risks, and dietary therapies recently emerged as promising avenues to achieve non-invasive management of a wide spectrum of diseases.

Identification of Candidate Genes for Lint Percentage and Fiber Quality Through QTL Mapping and Transcriptome Analysis in an Allotetraploid Interspecific Cotton CSSLs Population.

Upland cotton () has long been an important fiber crop, but the narrow genetic diversity of modern limits the potential for simultaneous improvement of yield and fiber quality. It is an effective approach to broaden the genetic base of through introgression of novel alleles from with excellent fiber quality. In the present study, an interspecific chromosome segment substitution lines (CSSLs) population was established using cultivar Pima S-7 as the donor parent and cultivar CCRI35 as the recipient parent.

Correlation between functional disability and quality of life among rural elderly in Anhui province, China: a cross-sectional study.

Objective: We aimed to explore the correlation between functional disability and quality of life (QoL). And exploring the interaction of functional disability, basic demographic characteristics and health-related information on QoL among the rural elderly in Anhui Province.

Methods: This study used multi-stage stratified cluster sampling in rural Anhui Province from January to July 2018 to conduct a cross-sectional survey of older adults who met the inclusion criteria.

Astrocytic p75 expression provoked by ischemic stroke exacerbates the blood-brain barrier disruption.

The disruption of the blood-brain barrier (BBB) plays a critical role in the pathology of ischemic stroke. p75 neurotrophin receptor (p75 ) contributes to the disruption of the blood-retinal barrier in retinal ischemia. However, whether p75 influences the BBB permeability after acute cerebral ischemia remains unknown.

Nogo receptor impairs the clearance of fibril amyloid-β by microglia and accelerates Alzheimer's-like disease progression.

Alzheimer's disease (AD) is characterized by the progressive accumulation of β-amyloid (Aβ)-containing amyloid plaques, and microglia play a critical role in mediating Aβ clearance. Mounting evidence has confirmed that the ability of microglia in clearing Aβ decreased with aging and AD progress, but the underlying mechanisms are unclear. Previously, we have demonstrated that Nogo receptor (NgR), a receptor for three axon growth inhibitors associated with myelin, can decrease adhesion and migration of microglia to fibrils Aβ with aging.

Long-term inhibition of dipeptidyl-peptidase 4 reduces islet infiltration and downregulates IL-1β and IL-12 in NOD mice.

Dipeptidyl-peptidase 4 (DPP-4) inhibitor (sitagliptin) is a novel anti-hyperglycemia drug in the treatment of type 2 diabetes. However, its potential in type 1 diabetes is still unclear. Recent studies show that increased infection, especially respiratory tract infection, is significantly associated with DPP-4 inhibitors.

The CD200/CD200R signaling pathway contributes to spontaneous functional recovery by enhancing synaptic plasticity after stroke.

Background: Spontaneous functional recovery occurs during the acute phase after stroke onset, but this intrinsic recovery remains limited. Therefore, exploring the mechanism underlying spontaneous recovery and identifying potential strategies to promote functional rehabilitation after stroke are very important. The CD200/CD200R signaling pathway plays an important role in neurological recovery by modulating synaptic plasticity during multiple brain disorders.

The accumulation of microplastics in fish from an important fish farm and mariculture area, Haizhou Bay, China.

Marine fisheries and aquaculture can match growing demand for marine protein from an increasing population. However, the microplastics (MPs) in marine environments may pose a threat to human health through food chains by seafood consumption. The MPs have been found lodged in the digestive tracts and other tissues of various sea animals, nevertheless, little is known in regard to the accumulation of MPs in fish from major fish farms and mariculture areas, especially in non-digestive tissues of fishes.

[Determination of organochlorine and organophosphorus pesticides in soil by gas chromatography-tandem mass spectrometry with accelerated solvent extraction].

A method based on gas chromatography-tandem mass spectrometry (GC-MS/MS) coupled with accelerated solvent extraction (ASE) was developed for the determination of eight organochlorine pesticides (OCPs) and five organophosphorus pesticides (OPPs) in soils. The soil samples were grinded after freeze-drying. Particles with diameters lower than 250 μm were chosen by ion-sieving.

Distribution, sources, and ecological risk assessment of SVOCs in surface sediments from Guan River Estuary, China.

The contamination of semi-volatile organic compounds (SVOCs) in the surface sediments of the Guan River Estuary, China was fully investigated. Total concentrations of 56 species of SVOCs ranged from 132 to 274 ng/g with an average of 186 ng/g (dry weight). Polycyclic aromatic hydrocarbon (PAH) concentrations were positively correlated with clay content and negatively correlated with sediment grain size.
