文摘Physical activity,moderate aerobic or resistance exercise are well established to offer health benefits and promote healthy aging and longevity.^(1)In contrast,lack of exercise contributes to adverse events,especially in some patients with organ failure.^(2)Therefore,“exercise pills”and“exercise mimetics”have attracted growing interest because of their potential to induce exercise-related health effects despite physical exercise not being performed.^(3)Robust studies over the past decade have identified many natural biomacromolecules,such as peptide,non-coding Ribonucleic Acid(RNAs),and lipids,that are induced by exercise.^(4-6)These molecules trigger physiological adaptations,including promotion of cardiomyocyte proliferation,anti-apoptotic capacity,and healthy tissue growth.7However,identifying or designing an exercise pill that mimics the extensive benefits of exercise is still challenging.

文摘Background:Midlife lifestyle factors,including physical activity,are associated with late-life brain health,yet the role of aerobic exercise on structural brain health in early and mid-adulthood remains poorly understood.This study aimed to examine the effect of aerobic exercise on structural brain age and to explore potential mediators.Methods:In a single-blind,12-month randomized clinical trial,130 healthy participants aged 26-58 years were randomized into a moderate-to-vigorous intensity aerobic exercise group or a usual-care control group.The exercise group attended two supervised 60-min sessions per week in a laboratory setting plus engaged in home-based exercise to achieve 150 min of exercise per week.Brain-predicted age difference(brain-PAD)and cardiorespiratory fitness(CRF)were assessed at baseline and 12 months.Both intention-to-treat(ITT)and completers analyses(including participants who completed post-intervention assessments)were performed.Results:The 130 participants(67.7%female)had an age of 41.28±9.93 years(mean±SD).At baseline,higher CRF(peak oxygen uptake,VO_(2peak))was associated with smaller brain-PAD(β=-0.309,p=0.012).After the intervention,the exercise group showed a decrease in brainPAD(estimated mean difference(EMD)=-0.60;95%confidence interval(95%CI):-1.15 to-0.04;p=0.034)compared to the control group(EMD=0.35;95%CI:-0.21 to 0.92;p=0.217);time×group interaction(between-group difference(BGD)=-0.95;95%CI:-1.72 to-0.17;p=0.019).VO2peak improved in the exercise group(EMD=1.60;95%CI:0.29-2.90;p=0.017)compared to the control group(EMD=-0.78;95%CI:-2.17 to 0.60;p=0.265);time×group interaction(BGD=2.38;95%CI:0.52-4.25;p=0.015).Body composition,blood pressure,and brain-derived neurotrophic factor levels were unaffected.None of the proposed pathways statistically mediated the effect of exercise on brain-PAD.The results from completers were similar.Conclusion:Engaging in 12 months of moderate-to-vigorous exercise reduced brain-PAD in early-to-midlife adults.The pathways by which these effects occur remain unknown.

文摘Early prevention and control of coal spontaneous combustion have emerged as a critical research area in coal mine safety.Due to their sustainability and environmental friendliness,microorganisms have gained attention.A filamentous fungus was collected in the coal mine and identified as Absidia spinosa.Results indicated that the mycelium effectively covered and repaired many coal pores.The oxygen consumption ratio of A.spinosa was higher in coal-containing environments than in coal-free conditions.The fungus significantly impacted aliphatic functional groups,disrupting bridging bonds and side chains connected to aromatic structures and reducing the relative content of C—O bonds.Additionally,A.spinosa increases the ignition temperature by 25.34℃.The total heat release was decreased by approximately 32.58%,and the activation energies were increased.The genome of Absidia spinosa revealed genes related to oxygen consumption,small molecule degradation,and secretion of metabolic products,such as those annotated under GO ID:0140657,etc.The pathways involved in the degradation of small organic molecules(e.g.,ko00626,etc.),carbon fixation,and nitrogen cycling,all linked to coal decomposition.Through oxygen consumption and the alteration of coal-active structures,A.spinosa effectively inhibits CSC,providing an experimental basis for exploring eco-friendly biological control methods in the goaf.

文摘BACKGROUND Type 2 diabetes mellitus(T2DM),a chronic metabolic disease with a high global incidence,has become a serious public health challenge.China has the largest number of T2DM patients worldwide,imposing a significant economic burden on the healthcare system.T2DM is closely associated with insulin resistance,impaired pancreatic B cell function,and disordered glucose and lipid metabolism,which can lead to various complications,reducing patients'quality of life and increasing the risk of disability and death.Thus,finding effective preventive and intervention measures is crucial.Exercise therapy,a key part of diabetes management,has gained attention in recent years,with many studies indicating its benefits for blood glucose control and other aspects in diabetic patients.AIM To assess the effectiveness of combined resistance and aerobic exercise interventions on blood glucose control and metabolic indicators in patients with T2DM and to explore their application in diabetes management.METHODS Systematic searches were conducted using PubMed,EMBASE,Cochrane Library,and Chinese databases for relevant randomized controlled trials(RCTs).The inclusion criteria were participants aged≥18 years with T2DM and the intervention involved combined resistance and aerobic exercise for≥8 weeks.The primary outcome indicators were fasting blood glucose,low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),triglycerides(TG),glycated hemoglobin A1c(HbA1c),and total cholesterol(TC)levels.Data analysis was performed using RevMan software,and the interventional effects were assessed using weighted mean differences or standardized mean differences(SMD).RESULTS Six RCTs meeting the inclusion criteria were included,with a total sample size of 366 participants.The meta-analysis results showed that combined resistance and aerobic exercise significantly improved several metabolic indicators in patients with T2DM.Specific results were as follows:(1)For fasting blood glucose,combined exercise was more effective than aerobic exercise alone[SMD=1.22;95%confidence interval(95%CI):0.70,1.74;P<0.00001];(2)LDL-C levels were significantly reduced by the combined intervention(SMD=1.45;95%CI:1.18-1.72;P<0.00001);(3)The combined intervention significantly increased HDL-C levels(SMD=1.42;95%CI:0.98-1.87;P<0.00001);(4)The combined intervention significantly reduced TG levels(SMD=1.12;95%CI:0.85-1.39;P<0.00001;(5)No statistically significant difference was observed in HbA1c between the combined and the aerobic exercise group(SMD=-0.03;95%CI:-1.09 to 1.04;P<0.00001);and(6)The combined exercise intervention group significantly reduced TC levels(SMD=2.66;95%CI:1.93-3.38;P<0.00001).The subgroup analysis results suggest that the effect of exercise interventions may be influenced by various factors,including the patient's age,baseline blood glucose levels,and exercise intensity.CONCLUSION Combined resistance and aerobic exercise intervention significantly improved fasting blood glucose,LDL-C,HDL-C,TG,and TC levels in patients with T2DM,especially in terms of blood glucose control and cardiovascular risk,demonstrating better outcomes than aerobic exercise alone.

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Probiotics have been demonstrated to be effective and safe for hyperuricemia(HUA)and gout treatment.Hence,identifying microbes with high uric acid-or purine-metabolizing ability is highly important.Due to the high load of uric acid in chicken feces,we hypothesized that the chicken gut would be an excellent source for new uric acid or purine-metabolizing microbes.In this study,we examined chicken gut contents to isolate an Enterococcus faecalis strain(designated CML390)that displayed high uric acid-degrading ability.In vitro experiments indicated that E.faecalis CML390 could effectively metabolize uric acid under both aerobic and anaerobic conditions,and the richer the nutrients,the higher the rate of uric acid degradation.By integrating genomics,transcriptomics,and metabolomics analyses,we revealed two pathways involved in aerobic and anaerobic uric acid degradation,respectively,in this isolate.E.faecalis CML390 relies on oxygen to metabolize uric acid into substances such as allantoin under aerobic conditions,while it also harbors a conserved uric acid-inducible gene cluster for anaerobic uric acid metabolism.An in vivo experiment showed that gavage with live E.faecalis CML390 in a mouse model of HUA(established using a combination of uric acid and potassium oxonate)significantly reduced serum uric acid levels and alleviated HUA.Our findings contribute to the exploration of the pathways and mechanisms of uric acid metabolism in intestinal microorganisms and provide a candidate probiotic for the treatment of HUA and gout.

文摘The ocean represents a vast carbon reservoir,where methane concentrations reflect a balance between production and consumption processes.In this study,marine sediments harboring abundant aerobic methanotrophs were incubated under varying methane concentrations.We investigated changes in methane oxidation rates and the community structure of these methanotrophs during incubation.Results demonstrate that methane concentration regulates aerobic methane oxidation.The oxidation rate increased with rising methane concentration up to 50%.However,beyond this threshold,at 80%methane,the oxidation rate declined.Following incubation,the abundance of aerobic methanotrophs increased significantly,with Methylobacterium becoming the dominant genus.Relative abundances of other bacteria potentially associated with alkane degradation,including Planomicrobium,Bacillus,Methylophaga,Erythrobacter,Gillisia and Pontibacter,were also significantly enriched.These findings provide a scientific basis for predicting marine methane emission dynamics,which is crucial for assessing and mitigating the greenhouse gas impact of methane.

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Purpose:The purpose of this narrative review is to:1)summarize findings from the three Studies of a Targeted Risk Reduction Intervention through Defined Exercise(STRRIDE)randomized trials regarding the differential effects of exercise amount,intensity,and mode on metabolic syndrome(MetS);and 2)compare the STRRIDE findings with other published randomized exercise trials related to changes in MetS.Methods:A literature review was performed to investigate the effects of exercise on composite measures of MetS.PubMed was searched between October 2023 and December 2023.To be included in this review,studies must have employed a randomized study design,whereby exercise amount,intensity,or mode was varied.Results:Findings from the STRRIDE trials and other randomized exercise trials suggest:1)there is a relationship between exercise energy expenditure(ExEE)and improvements in composite measures of MetS;2)there may be an asymptotic effect for ExEE beyond which further improvements in MetS are negligible or counterproductive;3)improvements in composite measures of MetS are closely linked to insulin sensitivity;and 4)without controlling for total ExEE,combined aerobic and resistance training interventions offer the most robust improvements for composite MetS outcomes compared to either mode alone.Conclusion:Additional,large-scale,randomized exercise trials should be designed to investigate the potential asymptotic effect and associated threshold for ExEE,the interaction between exercise intensity and baseline insulin sensitivity,and the independent effects of exercise mode on MetS.
