文摘Background Evidence on the effects of different exercise interventions on cognitive function is insufficient.Aims To evaluate the feasibility and effects of remotely supervised aerobic exercise(AE)and resistance exercise(RE)interventions in older adults with mild cognitive impairment(MCI).Methods This study is a 6-month pilot three-arm randomised controlled trial.Eligible participants(n=108)were recruited and randomised to the AE group,RE group or control(CON)group with a 1:1:1 ratio.Interventions were delivered at home with remote supervision.We evaluated participants’global cognition,memory,executive function,attention,physical activity levels,physical performance and muscle strength of limbs at baseline,3 months(T1)and 6 months(T2)after randomisation.A linear mixed-effects model was adopted for data analyses after controlling for covariates.Tukey’s method was used for adjusting for multiple comparisons.Sensitivity analyses were performed after excluding individuals with low compliance rates.Results 15(13.89%)participants dropped out.The median compliance rates in the AE group and RE group were 67.31%and 93.27%,respectively.After adjusting for covariates,the scores of the Alzheimer’s Disease Assessment Scale-Cognitive subscale in the AE group decreased by 2.04(95%confidence interval(CI)−3.41 to−0.67,t=−2.94,p=0.004)and 1.53(95%CI−2.88 to−0.17,t=−2.22,p=0.028)points more than those in the CON group at T1 and T2,respectively.The effects of AE were still significant at T1(estimate=−1.70,95%CI−3.20 to−0.21,t=−2.69,p=0.021),but lost statistical significance at T2 after adjusting for multiple comparisons.As for executive function,the Stroop time interference in the RE group decreased by 11.76 s(95%CI−21.62 to−1.90,t=−2.81,p=0.015)more than that in the AE group at T2 after Tukey’s adjustment.No other significant effects on cognitive functions were found.Conclusions Both remotely supervised AE and RE programmes are feasible in older adults with MCI.AE has positive effects on global cognition,and RE improves executive function.
文摘[Objectives]To synthesize evidence on HIIT versus moderate-intensity continuous training(MICT)or routine rehabilitation in stroke survivors.[Methods]We systematically searched 8 databases(PubMed,EMBASE,CENTRAL,Web of Science,SPORTSDiscus,PsycINFO,SCOPUS,CINAHL)up to May 2025.Seventeen randomized controlled trials(RCTs;total n=1142)met inclusion criteria:adults with stroke,device-based HIIT(≥70%HRR/VO 2peak),and outcomes assessing VO 2peak,6-min walk distance(6MWD),or Berg Balance Scale(BBS).Methodological quality was evaluated using the PEDro scale.Pooled effect sizes(Hedges'g)were calculated via random-effects models,with heterogeneity quantified by I^(2).[Results]HIIT significantly improved peak oxygen uptake(VO 2peak)versus controls(g=0.59,95%CI:0.44-0.75,p<0.001;I^(2)=16.29%).Low heterogeneity and symmetrical funnel plots supported robustness.HIIT also enhanced walking endurance(6MWD:g=0.32,95%CI:0.16-0.48,p<0.01;I^(2)=30%).In contrast,no significant benefit was observed for balance function(BBS:g=0.07,95%CI:-0.13-0.26,p=0.50;I^(2)=0%).[Conclusions]HIIT is a safe and highly effective intervention for enhancing aerobic capacity and walking function post-stroke.Its benefits are maximized at higher intensities and longer durations but do not extend to balance improvement.Integrating HIIT into stroke rehabilitation protocols is strongly recommended to promote functional independence.

文摘The conversion of waste resources into fertilizer represents a crucial strategy for optimizing waste utilization and attaining"carbon peak and neutrality"objectives.This approach not only effectively mitigates greenhouse gas emissions but also enhances the organic matter content in soil,thereby supporting the advancement of sustainable agriculture.Currently,the principal fertilizer production technologies utilizing solid waste resources encompass hydrothermal fertilizer production,aerobic fermentation,wrapping fertilizer production,micro-storage fertilizer production,and biochemical rapid decomposition.This paper examines the applicability and limitations of these technologies in practical contexts,and anticipates their developmental trends and future prospects.It aims to offer practical guidance and constructive support for the resource utilization of solid waste and the sustainable development of related industries.
文摘Exercise is a therapeutic approach in cancer treatment,providing several benefits.Moreover,exercise is associated with a reduced risk for developing a range of cancers and for their recurrence,as well as with improving survival,even though the underlying mechanisms remain unclear.Preclinical and clinical evidence shows that the acute effects of a single exercise session can suppress the growth of various cancer cell lines in vitro.This suppression is potentially due to altered concentrations of hormones(e.g.,insulin)and cytokines(e.g.,tumor necrosis factor alpha and interleukin 6)after exercise.These factors,known to be involved in tumorigenesis,may explain why exercise is associated with reduced cancer incidence,recurrence,and mortality.However,the effects of short-(<8 weeks)and long-term(≥8 weeks)exercise programs on cancer cells have been reported with mixed results.Although more research is needed,it appears that interventions incorporating both exercise and diet seem to have greater inhibitory effects on cancer cell growth in both apparently healthy subjects as well as in cancer patients.Although speculative,these suppressive effects on cancer cells may be driven by changes in body weight and composition as well as by a reduction in low-grade inflammation often associated with sedentary behavior,low muscle mass,and excess fat mass in cancer patients.Taken together,such interventions could alter the systemic levels of suppressive circulating factors,leading to a less favorable environment for tumorigenesis.While regular exercise and a healthy diet may establish a more cancer-suppressive environment,each acute bout of exercise provides a further“dose”of anticancer medicine.Therefore,integrating regular exercise could potentially play a significant role in cancer management,highlighting the need for future investigations in this promising area of research.

文摘Background:Statins are the cornerstone of low-density lipoprotein cholesterol(LDL-C)-lowering therapy;however,the therapeutic efficacy of statins in countering atherosclerotic cardiovascular disease(ASCVD)is compromised by the concurrent elevation of proprotein convertase subtilisin/kexin type 9(PCSK9),a pivotal molecule that increases LDL-C levels.Aerobic exercise lowers PCSK9 levels,but the underlying mechanism remains unclear.Therefore,we investigated how aerobic exercise can ameliorate statin-induced increases in PCSK9 levels.Methods:Three-week-old male American Institute of Cancer Research(ICR)mice were fed a high-fat-cholesterol diet(HFD)for 12 weeks and then administered atorvastatin alone or atorvastatin combined with aerobic exercise(Statin+Ex).Moreover,a total of 165 participants with stable coronary heart disease(CHD)enrolled at the Inpatient and Outpatient Departments of the Second Xiangya Hospital of Central South University,China,from January 2018 to July 2020 were randomized into the Statin group(male/female=51/33)and Statin+Ex group(male/female=52/29).Patients in the Statin+Ex group underwent treadmill exercise of 45-60 min/day for 7 days.Results:Aerobic exercise effectively alleviated statin-induced PCSK9 upregulation in human patients with CHD and hypercholesterolemic ICR mice(all p<0.05).Mechanistically,our findings revealed that aerobic exercise induced elevated epoxyeicosatrienoic acids(EETs)plasma levels while concurrently reducing the activity of soluble epoxide hydrolase(sEH)(all p<0.05),an enzyme responsible for EETs degradation.Further,EETs significantly suppressed PCSK9 expression,subsequently reducing the LDL-C levels(all p<0.05);this effect was mediated via the activation of the forkhead box O3a-silent mating type information regulation 2 homolog 6(FoxO3a-Sirt6)axis,with no impact on the sterol regulatory element binding protein 2 and 3-hydroxy-3-methylglutaryl-CoA reductase(SREBP2-HMGCR)pathway.Conclusion:Our study sheds light on the paradigm of"Exercise is Medicine",providing evidence to support the use of statins combined with exercise in reducing LDL-C levels,and unveils potential avenues for clinical applications of sEH inhibitors,presenting novel prospects for therapeutic interventions in ASCVD.

文摘Objectives:Aerobic exercise training can increase skeletal muscle mitochondrial content.Supine exercise training with legs above the heart potentially augments these increases.However,the impact of supine exercise training on mitochondrial biogenesis and cardiovascular adaptations remains unclear.Methods:In this single-centred,randomized,parallel arm trial,19 recreationally active individuals underwent seven sessions of either supine with legs up(SUP;n=9,6 females)or upright with legs down(UP;n=10,7 females)aerobic training on a recumbent bike at 71±7%and 71±2%of peak work rate(WRpeak),respectively.The study aimed to test the effects of training with decreased muscle oxygenation on indices of muscle mitochondrial remodelling.Secondary outcomes included exercise performance,muscle oxygenation,and cardiovascular responses.Results:Secondary outcomes revealed significant interaction effects for time to fatigue(TTF)and WRpeak in the SUP group during supine testing,suggesting enhanced exercise tolerance and performance.No between group interaction effects were observed for upright testing.No clear effects on mitochondrial biogenesis were observed based on expression of mitochondrial protein subunits and transcriptional regulators.Acutely,HRpeak was lower during the SUP Test compared to the UP Test.No central cardiovascular adaptations were observed following training.Conclusions:Our exploratory analyses showed that supine aerobic training more effectively improves supine exercise tolerance and performance compared with upright training,despite no differences in measured proteins related to mitochondrial biogenesis.Further research is needed to elucidate the mechanisms underlying these postural-specific training effects.Registration:clinicaltrials.gov:NCT04151095.
文摘Catalytic oxidation plays a crucial role in chemical industry,in which the utilization of abundant and environmental-friendly oxygen(O_(2))as oxidant aligns with sustainable development principles in green chemistry.However,the intrinsic inertness of ground-state O_(2) molecule poses a long-standing challenge in developing an efficient non-noble metal-based catalyst.Herein,inspired by the electron transfer process in respiratory chain,we engineered long-range N_(V) to mediate Fe_(1) center for O_(2) activation in aerobic oxidation.Combined in/quasi-situ spectroscopic characterizations and control experiments suggest the Fe_(1) site efficiently adsorbs O_(2),and the N_(V) site facilitates electron delocalization to adjacent Fe_(1),providing efficient transformation of O_(2) to reactive oxygen species that boost oxidation reactions mildly.This Fe_(1)--N_(V) single-atom catalyst demonstrates outstanding catalytic performance in aerobic oxidations of alkanes,N-heterocycles,alcohols,and amines under relatively mild conditions.Our findings offer a new perspective for designing high-efficiency heterogeneous catalysts in aerobic oxidations,promising various potential applications.

文摘Background Exercise during neoadjuvant chemoradiotherapy(NCRT)has potential to mitigate treatment-related declines in physical fitness,and to improve clinical outcomes,including toxicity and tumor response.However,optimal frequency and timing of exercise remains to be determined.Therefore,this pilot trial aimed to assess feasibility of 2 different exercise interventions during NCRT in patients with esophageal and rectal cancer and to evaluate potential clinical effects.Methods Patients were randomized into 1 of 3 study arms during NCRT:(a)30-min aerobic exercise in-hospital within 1 h prior to each radiotherapy fraction(ExPR),(b)two 60-min supervised combined aerobic and resistance exercise sessions per week(AE+RE),and(c)usual care(UC).Feasibility was assessed by examining participation rate and exercise adherence.Intervention effects on physical fitness,health-related quality of life,treatment-related toxicity,and tumor response in patients with esophageal cancer were explored using regression analyses and 85%confidence intervals(85%CIs).Results Thirty-seven patients with esophageal cancer(participation rate=45%)and 2 patients with rectal cancer(participation rate=14%)were included.Median session attendance was 98%(interquartile range(IQR):96%–100%)in the ExPR and 78%(IQR:33%–100%)in the AE+RE group.We found clinically relevant benefits of exercise on maximal oxygen uptake(VO2_(max),mL/kg/min)(ExPR:β=9.7,85%CI:6.9–12.6;AE+RE:β=5.6,85%CI:2.6–8.5)and treatment-related toxicity(ExPR:β=–2.8,85%CI:–5.4 to–0.2;AE+RE:β=–2.6,85%CI:–5.3 to 0.0).Additionally,good tumor response was found in 70%in AE+RE and ExPR vs.55%in UC(odds ratio(OR)=1.9,85%CI:0.5–7.7).Conclusion Starting prehabilitation during NCRT is feasible,can increase starting fitness of traditional pre-surgical programs,and has potential to improve clinical outcomes.
