文摘Lithium–sulfur(Li–S)batteries are promisingcandidates for next-generation energy storagegiven their high energy density and potential low cost.Chemically activated carbon(CAC)is often used fortheir cathodes,because it has a high specific surfacearea for sulfur loading.We have developed a pressurizedphysical activation(PPA)method that producedan activated carbon(PPAC)with a high specific surfacearea comparable to that of CAC.The pore structure of PPAC could be changed and its use as a cathode material for Li–Sbatteries was investigated.Battery tests at different capacity rates(C-rates)showed that it had a much improved high-rate performancewith a discharge capacity of 900 mAh/(g of sulfur)at 1 C,in contrast to only 600 mAh/(g of sulfur)for CAC.Porestructure analyses showed that PPAC prepared at a high activation temperature(1000℃)had unusual channel-like mesoporesbetween the microdomains that are the basic structural units of artificial carbon materials.These are connected to microporesdeveloped in each microdomain,and deliver ions from the surroundings to the internal pores and vice versa.The well-developedmicropores and mesopores of PPAC respectively ensured the high adsorption of lithium polysulfides and a high rate ofion diffusion.Compared to CAC,PPAC is a high-performance,low-cost cathode material that is promising for use in futureLi–S batteries.

文摘To maintain soil quality under long-term saline water irrigation,the influence of manure on soil physical properties was examined.Long-term saline irrigation has been conducted from 2015 to 2024 at the Nanpi Eco-Agricultural Experimental Station of Chinese Academy Sciences in the Low Plain of the North China Plain,comprising four irrigation treatments:irrigation once at the jointing stage for winter wheat with irrigation water containing salt at fresh water,3,4 and 5 g·L^(–1),and maize irrigation at sowing using fresh water.Manure application was conducted under all irrigation treatments,with treatments without manure application used as controls.The results showed that under long-term irrigation with saline water,the application of manure increased the soil organic matter content,exchangeable potassium,available phosphorus,and total nitrogen content in the 0–20 cm soil layer by 46.8%,117.0%,75.7%,and 45.5%,respectively,compared to treatments without manure application.The application of manure reduced soil bulk density.It also increased the proportion of water-stable aggregates and the abundance of bacteria,fungi,and actinomycetes in the tillage soil layer compared to the controls.Because of the salt contained in the manure,the application of manure had dual effects on soil salt content.During the winter wheat season,manure application increased soil salt content.The salt content was significantly reduced during the summer maize season,owing to the strong salt-leaching effects under manure application,resulting in a smaller difference in salt content between the manure and non-manure treatments.During the summer rainfall season,improvements in soil structure under manure application increased the soil desalination rate for the 1 m top soil layer.The desalination rate for 0–40 cm and 40–100 cm was averagely by 39.1%and 18.9%higher,respectively,under manure application as compared with that under the nomanure treatments.The yield of winter wheat under manure application was 0.12%lower than that of the control,owing to the higher salt content during the winter wheat season.In contrast,the yield of summer maize improved by 3.9%under manure application,owing to the increased soil nutrient content and effective salt leaching.The results of this study indicated that manure application helped maintain the soil physical structure,which is important for the long-term use of saline water.In practice,using manure with a low salt content is suggested to reduce the adverse effects of saline water irrigation on soil properties and achieve sustainable saline water use.

文摘Overweight and obesity are significant public health concerns worldwide due to their association with many chronic health conditions.This has resulted in the development of various interventions focused on weight loss to reduce the associated health burden.Physical activity is an important lifestyle behavior associated with enhanced health.Evidence supports that many of the benefits of physical activity are realized independent of initial weight status or whether weight loss is achieved,with some benefits additive to what is achieved with weight loss alone.These benefits include enhanced cardiometabolic,brain,cognitive and psychological health,and others.Moreover,in adults with overweight or obesity,physical activity has independent effects on cardiorespiratory fitness,muscular strength,physical function,and mobility.There are also benefits to body composition,with physical activity improving the quality of key tissues,such as skeletal muscle,which may not occur with diet-induced weight loss.Therefore,physical activity is an important public health target for adults with overweight or obesity to provide a wide range of health benefits that extend beyond those of weight loss alone.However,physical activity recommendations and programming efforts should consider the unique characteristics of adults with overweight or obesity to be most effective,and should support a focus on mobility,physical function,and other health outcomes.

文摘Objective:We assessed the risk for physical inactivity due to inadequate health literacy using multivariable analysis in a large middleaged population.Methods:This cross-sectional mail survey using a self-administered questionnaire was conducted in 2020 and included 33,902 community residents aged 40-64 years from 5 cities in Osaka Prefecture,Japan.Of these,12,446(36.7%)agreed to participate in the survey.After exclusion of those with regular visits to medical institutions and those with missing data,the analysis included 3742 participants.Health literacy was measured by the communicative and critical health literacy(CCHL)scale,and participants were classified into 3 groups(low,medium,and high health literacy groups)by the tertiles of the CCHL scale score.Physical inactivity was defined as not completing at least 150 min of moderate-intensity physical activity throughout the week.Results:After adjustment for age,gender,education level,occupation,economic status,living alone,and stages of health behavior change,the multivariable-adjusted odds ratios(ORs)for physical inactivity were 1.36(95% confidence interval[CI]:1.16-1.59,P<0.001)in the medium health literacy group and 1.70(95%CI:1.36-2.11,P<0.001)in the low health literacy group compared with the high health literacy group.Conclusions:This large-scale study provides compelling evidence that those with inadequate health literacy are at higher risk for physical inactivity among middle-aged adults.
文摘Objective:To analyze the impact of maternal-infant separation on the physical and mental state of high-risk pregnancy patients and explore the clinical efficacy of targeted nursing interventions.Methods:A total of 80 high-risk pregnancy patients treated in our hospital from January 2023 to January 2024 were selected as the study subjects.These patients were randomly divided into an observation group and a control group(40 cases each)using a random number table.The control group received routine high-risk pregnancy nursing care,while the observation group received specialized maternal-infant separation nursing interventions in addition to routine care.The psychological and physiological states and nursing satisfaction of the two groups were compared before and after the intervention.Results:The SAS scores,SDS scores,and sleep quality scores of the observation group were significantly lower than those of the control group,with statistically significant differences(p<0.05).The incidence of postpartum hemorrhage in the observation group was significantly lower than that in the control group,and the initiation time of lactation was significantly earlier than that in the control group,with both differences being statistically significant(p<0.05).The nursing satisfaction of the observation group was significantly higher than that of the control group(80%vs.32/40),with a statistically significant difference(p<0.05).Conclusion:Maternal-infant separation exacerbates anxiety and depression in high-risk pregnancy patients,reduces sleep quality,increases the risk of postpartum hemorrhage,and delays the initiation of lactation.Specialized nursing interventions for maternal-infant separation can improve the physical and mental state of high-risk pregnancy patients,reduce the incidence of postpartum complications,and enhance nursing satisfaction,making them worthy of clinical application and promotion.

文摘Alzheimer's disease is the primary cause of dementia and imposes a significant socioeconomic burden globally.Physical exercise,as an effective strategy for improving general health,has been largely reported for its effectiveness in slowing neurodegeneration and increasing brain functional plasticity,particularly in aging brains.However,the underlying mechanisms of exercise in cognitive aging remain largely unclear.Adiponectin,a cell-secreted protein hormone,has recently been found to regulate synaptic plasticity and mediate the antidepressant effects of physical exercise.Studies on the neuroprotective effects of adiponectin have revealed potential innovative treatments for Alzheimer's disease.Here,we reviewed the functions of adiponectin and its receptor in the brains of human and animal models of cognitive impairment.We summarized the role of adiponectin in Alzheimer's disease,focusing on its impact on energy metabolism,insulin resistance,and inflammation.We also discuss how exercise increases adiponectin secretion and its potential benefits for learning and memory.Finally,we highlight the latest research on chemical compounds that mimic exerciseenhanced secretion of adiponectin and its receptor in Alzheimer's disease.
文摘Background:The topic of this review is the study of the gut microbiota(GM),and the use of probiotics,especially in humans,as a new frontier in the field of prevention and health in general.The beneficial effects and functions performed by probiotics in the GM are increasingly at the centre of both scientific,medical,and pharmaceutical interest.It is now known that diet and probiotics can modify the GM,although in these situations there is a need for greater and more in-depth research regarding the methods and timing of treatment.However,the relationship between physical activity,GM,and probiotics is still largely unclear,as regards certain mechanisms between physical exercise and probiotics in humans.Discussion:In this study,we tried to demonstrate whether and how physical exercise was able to alter the composition of the microbiota and how probiotics can facilitate it.Therefore,alteration of the microbiota was considered in terms of both diversity and composition.Conclusions:The ones examined propose vastly different physical exercises,both in terms of timing and type of intervention itself,and the use of probiotics.
文摘Background:Depression is prevalent among female college students,with eating behavior potentially related to this issue.This study examines the relationship between eating behavior and depression,focusing on the role of social appearance anxiety and physical activity.Methods:We recruited 2161 female college students from nine universities in China via convenience sampling.Data was collected via an online questionnaire.Eating behavior was assessed via the Eating Behavior Scale short form(EBS-SF),depression was measured via the Center for Epidemiological Studies Depression Scale(CES-D),social appearance anxiety was evaluated via the Social Appearance Anxiety Scale,and physical activity was assessed via a single-item question.Descriptive statistics were analyzed via SPSS 26.0,and moderated mediation analysis was conducted via PROCESS version 3.5.Results:Unhealthy eating behavior was significantly associated with higher levels of depression(β=0.285,p<0.001).Social appearance anxiety mediated this relationship,accounting for 46%of the total effect(β=0.132,95%CI=[0.108,0.158]).The interaction effect between eating behavior and physical activity was significantly and negatively correlated with depression(β=−0.052,p<0.01).The association between eating behavior and depression was stronger under conditions of low physical activity(β=0.210,p<0.001)than under conditions of high physical activity(β=0.105,p<0.001).Conclusions:Integrating nutritional guidance,body image acceptance training,and exercise promotion into campus mental health programs is crucial for addressing depression in female college students.Future research should use longitudinal designs and broader participant ranges to increase the general applicability of the findings.

文摘White matter injury is a key factor impacting stroke recovery.Physical exercise can promote white matter repair.Immune cells,especially regulatory T(Treg)cells,contribute to strengthening white matter integrity,yet little is known about the underlying mechanism.To examine this,we established a transient middle cerebral artery occlusion male mouse model.We found that physical exercise elevated brain Treg cells,thereby enhancing neurological recovery,reducing neuroinflammation,promoting myelin debris clearance,and accelerating white matter repair.Depletion of Treg cells caused a decrease in these positive effects of physical exercise.Mechanistically,the rise in osteopontin triggered by physical exercise is dampened when Treg cells are depleted.In addition,Treg-conditioned medium reduced oxygen-glucose deprivation/re-oxygenation-induced microglial inflammation and enhanced phagocytosis,which could be blocked by osteopontin antibodies.Importantly,although Treg infusion could mimic the protective effects of physical exercise,osteopontin blockade partially countered the effects of physical exercise and Treg cells.Finally,our sequencing data revealed a marked upregulation of C-X-C motif chemokine ligand 12(CXCL12)mRNA expression subsequent to physical exercise,which was confirmed at the protein level.Stimulation of Treg cells with stroke brain lysates increased C-X-C motif chemokine receptor 4(CXCR4)expression,indicating a potential role for the CXCL12-CXCR4 axis in recruiting Treg cells.These findings suggest that physical exercise promotes white matter repair after ischemic stroke by Treg cells.

文摘Diabetes mellitus(DM)has become one of the most serious and common chronic diseases around the world,leading to various complications and a reduction in life expectancy.Increased sedentary behavior(SB)and decreased physical activity(PA)are important contributors to the rising prevalence of DM.This article reviews the research progress on the pathogenesis of DM,the effects of SB and PA on the risk of DM,aiming to explore the influence of different PA intensities,amounts,frequencies,durations and types on the incidence of DM.Research has shown that blood glucose levels tend to increase with the prolongation of SB.Within a certain range,PA intensity and PA amount are negatively correlated with the risk of DM;Performing PA for more than 3 days per week maintains normal glucose tolerance and lower blood pressure;Engaging in 150–300 min of moderate intensity exercise or 75–150 min of high-intensity exercise per week reduces the risk of DM;PA during leisure time reduces the risk of DM,while PA during work increases the risk of DM;Both aerobic training and resistance training reduce the risk of DM,and the combination of the two training methods produces better benefits;Various types of exercises,such as cycling,soccer,aerobics,yoga,tai chi,all reduce the risk of DM.In summary,prolonged SB increases the risk of DM,while appropriate PA reduces the risk of DM.As the intensity,amount,and frequency of PA increase,the effect of reducing DM risk becomes more significant.Different exercise methods have different effects on reducing DM risk.

文摘The ongoing revolution in information technology is reshaping human life. In the realm of health behavior, wearable technology emerges as a leading digital solution,capturing physical behaviors (i.e., physical activity, sedentary habits, sleep patterns) within the 24-h cycle of daily life. Wearables are applied in research, clinical practice, and as lifestyle devices;most obvious, they promise to be a key element for increasing human physical activity, one of the biggest health challenges nowadays.
文摘Physical inactivity remains a pressing global public health concern.Prolonged periods of sedentary behavior have been linked to heightened risks of non-communicable diseases such as cardiovascular diseases and type 2 diabetes,while engaging in any form of physical activity can elicit favorable effects on health.Nevertheless,epidemiological research indicates that people often struggle to meet recommended physical activity guidelines,citing time constraints,lack of exercise equipment,and environmental limitations as common barriers.Exercise snacks represents a time-efficient approach with the potential to improve physical activity levels in sedentary populations,cultivate exercise routines,and enhance the perception of the health benefits associated with physical activity.We review the existing literature on exercise snacks,and examine the effects of exercise snacks on physical function and exercise capacity,while also delving into the potential underlying mechanisms.The objective is to establish a solid theoretical foundation for the application of exercise snacks as a viable strategy for promoting physical activity and enhancing overall health,particularly in vulnerable populations who are unable to exercise routinely.

文摘A complex geological environment with faults can be encountered in the process of coal mining.Fault activation can cause instantaneous structure slipping,releasing a significant amount of elastic strain energy during underground coal mining.This would trigger strong rockburst disasters.To understand the occurrence of fault-slip induced rockbursts,we developed a physical model test system for fault-slip induced rockbursts in coal mine drifts.The boundary energy storage(BES)loading apparatus and bottom rapid retraction(BRR)apparatus are designed to realize energy compensation and continuous boundary stress transfer of the surrounding rocks for instantaneous fault slip,as well as to provide space for the potential fault slip.Taking the typical fault-slip induced rockburst in the Xinjulong Coal Mine,China,as the background,we conducted a model test using the test system.The deformation and stress in the rock surrounding the drift and the support unit force during fault slip are analyzed.The deformation and failure characteristics and dynamic responses of drifts under fault-slip induced rockbursts are obtained.The test results illustrate the rationality and effectiveness of the test system.Finally,corresponding recommendations and prospects are proposed based on our findings.

文摘Accurate estimation of mineralogy from geophysical well logs is crucial for characterizing geological formations,particularly in hydrocarbon exploration,CO_(2) sequestration,and geothermal energy development.Current techniques,such as multimineral petrophysical analysis,offer details into mineralogical distribution.However,it is inherently time-intensive and demands substantial geological expertise for accurate model evaluation.Furthermore,traditional machine learning techniques often struggle to predict mineralogy accurately and sometimes produce estimations that violate fundamental physical principles.To address this,we present a new approach using Physics-Integrated Neural Networks(PINNs),that combines data-driven learning with domain-specific physical constraints,embedding petrophysical relationships directly into the neural network architecture.This approach enforces that predictions adhere to physical laws.The methodology is applied to the Broom Creek Deep Saline aquifer,a CO_(2) sequestration site in the Williston Basin,to predict the volumes of key mineral constituents—quartz,dolomite,feldspar,anhydrite,illite—along with porosity.Compared to traditional artificial neural networks (ANN),the PINN approach demonstrates higher accuracy and better generalizability,significantly enhancing predictive performance on unseen well datasets.The average mean error across the three blind wells is 0.123 for ANN and 0.042 for PINN,highlighting the superior accuracy of the PINN approach.This method reduces uncertainties in reservoir characterization by improving the reliability of mineralogy and porosity predictions,providing a more robust tool for decision-making in various subsurface geoscience applications.
文摘BACKGROUND While existing literature on ischiofemoral impingement syndrome(IFI)predominantly emphasizes surgical interventions or generalized physical therapy approaches,there remains a paucity of evidence regarding structured,multimodal rehabilitation programs targeting biomechanical deficits in IFI.This case report evaluates the efficacy of a multimodal rehabilitation program addressing a critical gap in conservative management strategies.CASE SUMMARY The patient underwent comprehensive physical and clinical examination,including hip X-ray and magnetic resonance imaging investigations.The patient completed the Musculoskeletal Health Questionnaire(MSK-HQ)and numerical pain rating scale(NPRS).The patient underwent a two-month tailored structured physical therapy intervention and repeated the same assessment afterwards.The patient's substantial reduction in pain,reflected by a significant decrease in the patient’s NPRS score from 9 to 3 points,signifies a positive clinical response.This outcome,coupled with the significant improvement in the patient's health-related quality of life according to the MSK-HQ score,which increased from 12 to 48 points,underscores the success of our research.CONCLUSION The study highlights the importance of a comprehensive approach to diagnosing and managing IFI,combining clinical assessment with imaging and implementing a multimodal rehabilitation program for optimal outcomes.

文摘The frontal edge of the Makran accretionary wedge is characterized by the development of multiple imbricate thrust faults trending E-W and relatively parallel.However,the mechanisms underlying their formation and the factors controlling their development remain subjects of debate.This paper,based on seismic profile analysis,employs physical simulation experiments to establish a'wedge'type subduction model.The study explores the influence of the initial wedge angle,horizontal sand layer thickness,and the presence or absence of a decollement layer on the structural styles of the thrust wedge.Experimental results indicate that as the initial wedge angle decreases from 11°to 8°,the lateral growth of the thrust wedge increases,whereas vertical growth diminishes.When the horizontal sand layer thickness is reduced from 4.5 cm to 3.0 cm,the spacing between the frontal thrusts decreases and the number of thrust faults increases.Both lateral and vertical growth are relatively reduced,resulting in a smaller thrust wedge.When a decollement layer is present,the structural style exhibits layered deformation.The decollement layer constrains the development of back thrusts and promotes the localized formation of frontal thrusts.In conclusion,the imbricate thrust faults at the frontal edge of the Makran accretionary wedge are primarily controlled by the characteristics of the wedge itself and the presence of the decollement layer.

文摘Electrochemical metallurgy at low temperature(<473 K)shows promise for the extraction and refinement of metals and alloys in a green and sustainable manner.However,the kinetics of the electrodeposition process is generally slow at low temperature,resulting in large overpotential and low current efficiency.Thus,the application of external physical fields has emerged as an effective strategy for improving the mass and charge transfer processes during electrochemical reactions.This review highlights the challenges associated with low-temperature electrochemical processes and briefly discusses recent achievements in optimizing electrodeposition processes through the use of external physical fields.The regulating effects on the optimization of the electrodeposition process and the strategies for select-ing various external physical fields,including magnetic,supergravity,and ultrasonic fields are summarized from the perspectives of equipment and mechanisms.Finally,advanced methods for in-situ characterization of external physical field-assisted electrodeposition processes are reviewed to gain a deeper understanding of metallic electrodeposition.An in-depth exploration of the mechanism by which external physical fields affect the electrode process is essential for enhancing the efficiency of metal extraction at low temperatures.
文摘BACKGROUND Long-term chemotherapy for patients with gastric cancer(GC),facilitated by peripherally inserted central catheter(PICC)catheterization,reduces vascular damage and enhances drug delivery efficiency but carries risks of catheter-related complications.A combination of group psychological nursing and physical mo-vement care significantly mitigates the risk of venous thrombosis and improves psychological well-being,and enhances motor function,underscoring its clinical importance.AIM To assess group psychological and physical movement nursing in preventing venous thrombosis in patients with PICC GC.METHODS Sixty-five GC patients with PICC,admitted from January 2022 to January 2023,were randomly divided into two groups using the lottery method:A control group(n=35,routine nursing)and an observation group(n=30,routine nursing plus psychological nursing and physical movement nursing).Both groups re-ceived continuous care for 2 weeks.Pre-nursing and post-nursing data on psycho-logical state,physical function,chemotherapy-related thrombosis incidence,and cancer-related fatigue were analyzed using SPSS 26.0 and GraphPad Prism 8.0.RESULTS After nursing,both groups showed reduced Hamilton Anxiety Scale scores and increased General Perceived Self-Efficacy Scale scores,with the observation group performing better(P<0.05).The Functional Comprehensive Assessment score for the observation group after nursing was(65.42±2.35)points,lower than the control group’s(62.19±4.33)points(P<0.05).Although no significant difference was observed in the incidence of venous thrombosis between the two groups(χ2=0.815,P=0.367),the observation group had lower incidence.Both groups showed decreased Revised Piper Fatigue Scale scores,with the observation group scoring lower(P<0.05).CONCLUSION Group psychological and physical movement nursing for patients with PICC reduces venous thrombosis risk,improves psychological well-being,cancer-related fatigue,and physical function,making it highly promotable.

文摘In the ultra-deep strata of the Tarim Basin,the vertical growth process of strike-slip faults remains unclear,and the vertical distribution of fractured-cavity carbonate reservoirs is complex.This paper investigates the vertical growth process of strike-slip faults through field outcrop observations in the Keping area,interpretation of seismic data from the Fuman Oilfield,Tarim Basim,NW China,and structural physical simulation experiments.The results are obtained mainly in four aspects.First,field outcrops and ultra-deep seismic profiles indicate a three-layer structure within the strike-slip fault,consisting of fault core,fracture zone and primary rock.The fault core can be classified into three parts vertically:fracture-cavity unit,fault clay and breccia zone.The distribution of fracture-cavity units demonstrates a distinct pattern of vertical stratification,owing to the structural characteristics and growth process of the slip-strike fault.Second,the ultra-deep seismic profiles show multiple fracture-cavity units in the strike-slip fault zone.These units can be classified into four types:top fractured,middle connected,deep terminated,and intra-layer fractured.Third,structural physical simulation experiments and ultra-deep seismic data interpretation reveal that the strike-slip faults have evolved vertically in three stages:segmental rupture,vertical growth,and connection and extension.The particle image velocimetry detection demonstrates that the initial fracture of the fault zone occurred at the top or bottom and then evolved into cavities gradually along with the fault growth,accompanied by the emergence of new fractures in the middle part of the strata,which subsequently connected with the deep and shallow cavities to form a complete fault zone.Fourth,the ultra-deep carbonate strata primarily develop three types of fractured-cavity reservoirs:flower-shaped fracture,large and deep fault and staggered overlap.The first two types are larger in size with better reservoir conditions,suggesting a significant exploration potential.

文摘Infections associated with titanium(Ti)-based implants present significant challenges in clinical treatments,especially when biofilms already form on the implant surface.Many antimicrobial agents,including antibiotics,metallic nanoparticles and antimicrobial peptides,have been extensively used to deal with Ti implant infections.However,these chemical approaches suffer from potential toxicity,antibiotic resistance and poor long-term antibacterial performance.Hence,physical antibacterial surfaces on Ti-based implants have attracted increasing attention.The antibacterial behavior of different surfaces on Ti-based biomaterials against various bacteria only by physical properties of the implants themselves(e.g.,nanotopography)or exogenous physical stimulus(e.g.,photocatalysis)was reviewed,as well as parameters influencing the physical antibacterial processes,such as size,shape and density of the surface nanotextures,and bacterial growth phases.Besides,mechanisms of different fabrication techniques for the physical antibacterial surfaces on Ti-based biomaterials were also summarized.
