Keissl., which exhibits host specificity toward Populus species. To elucidate the molecular response mechanisms of A. alternata under fludioxonil fungicide stress, the fungus was cultured at the half-maximal effective concentration (EC₅₀) of fludioxonil. Transcriptomic and metabolomic profiles were analyzed using mycelia harvested under these conditions. Comparative analysis revealed 1,001 differentially expressed genes (DEGs) in the resistant strain (RS) relative to the wild-type strain (WT), comprising 628 upregulated and 373 downregulated genes. Concurrently, 524 differentially accumulated metabolites (DAMs) were identified, with 336 upregulated and 188 downregulated metabolites. KEGG pathway enrichment demonstrated pronounced upregulation in glycerophospholipid metabolism, α-linolenic acid metabolism, nucleic acid biosynthesis, and glycosylation processes. Conversely, arachidonic acid and galactose metabolism pathways were suppressed. Significant downregulation was observed in phosphatidylinositol signaling, aflatoxin biosynthesis, and cutin/suberin/wax biosynthesis pathways. Transcriptomic profiling further indicated that upregulated DEGs were predominantly associated with amino sugar/nucleotide sugar metabolism, ABC transporters, aflatoxin biosynthesis, and purine metabolism, while downregulated DEGs were enriched in N-glycan biosynthesis, endoplasmic reticulum protein processing, steroid biosynthesis, and riboflavin metabolism. Fludioxonil exerted substantial inhibitory effects on fungal growth, pathogenicity, and metabolic activity. Mechanistically, A. alternata counteracted fungicide-induced stress through modulation of its antioxidant defense system. This integrative multi-omics study delineates the dynamic gene expression and metabolic reprogramming in A. alternata under fludioxonil exposure, providing novel insights into potential molecular targets and informing the development of next-generation fungicidal strategies for phytopathogen control.展开更多

文摘We sincerely thank the authors of the commentary1 for their thoughtful analysis and constructive critique of our systematic review on ischemic preconditioning(IPC)and placebo effects in exercise capacity and athletic performance.2Their attention to methodological details,particularly concerning the inclusion and timing of warm-up protocols across studies,is commendable and contributes meaningfully to the ongoing refinement of IPC research in sports science.
文摘We highly commend Dr Souza et al.1for their systematic review research.The authors conducted a detailed investigation into the effects of ischemic preconditioning(IPC)on athletic performance,comparing it with placebo and no-intervention conditions.The study found that while IPC demonstrated superior effects over the no-intervention group in certain metrics(e.g.,time to exhaustion),its performance did not significantly surpass that of the placebo group.This suggests that the potential benefits of IPC may partially stem from participants’psychological expectations,or placebo effects.The study also highlighted the significant impact of placebo interventions on athletic performance,emphasizing the importance of distinguishing between placebo and no-intervention conditions in experimental designs.
文摘BACKGROUND Cardiac resynchronization therapy(CRT)has been a major therapeutic advancement for patients with heart failure and electrical dyssynchrony.While CRT improves symptoms,reduces hospitalizations,and enhances survival,the role of implantable cardioverter-defibrillators(ICDs)alongside CRT in patients with non-ischemic cardiomyopathy(NICM)remains controversial.To evaluate and compare the outcomes of CRT with ICD(CRT-D)versus CRT with pacemaker-only(CRT-P)in individuals diagnosed with NICM,with a specific focus on the elderly.METHODS A comprehensive search of PubMed,Embase,and the Cochrane Central Register of Controlled Trials was conducted in January 2024.Studies comparing CRT-D and CRT-P in patients with NICM were included,with subgroup analyses focusing on patients aged 75 years and older.RESULTS Twelve studies,including two randomized clinical trials,with a total of 62,145 patients and 16,754 pooled death events(9,171 in CRT-D and 7,583 in CRT-P),were analyzed.CRT-D was associated with a significantly lower risk of all-cause mortality compared to CRT-P(pooled OR=0.72;95%CI:0.61-0.85;P<0.01),with significant heterogeneity(I2=83%).RCT subgroup analysis,was not statistically significant(pooled OR=0.82;95%CI:0.64-1.06;P=0.41;I2=0%).In patients older than 75 years,no significant difference in mortality risk was observed(pooled OR 0.96;95%CI:0.81-1.15;I2=39%).CONCLUSION Our meta-analysis suggests that the addition of ICD therapy to CRT in patients with NICM significantly reduces all-cause mortality.However,this benefit does not extend to cardiovascular mortality,likely due to the primary role of ICDs in preventing sudden cardiac death rather than other causes such as progressive heart failure.The survival advantage of CRT-D is most pronounced in younger patients,with those over 75 years of age deriving less benefit.This highlights the importance of careful patient selection,considering age and comorbidities,when deciding on ICD implantation in NICM patients.

文摘BACKGROUND The beneficial effects of sodium-glucose co-transporter-2 inhibitors(SGLT2i)on adverse cardiac outcomes in diabetic patients are well-established.However,the effects of SGLT2i against cancer therapy-related cardiotoxicity remain understudied.We investigated the association between SGLT2i and cardiac outcomes in cancer patients.METHODS PubMed,Embase,and the Cochrane Library were searched from their inception until September 30,2024 for studies evaluating the effects of SGLT2i in patients with cancer.The primary outcomes included incident heart failure(HF),HF exacerbation,HF hospitalization,atrial fibrillation/atrial flutter(AF/AFL),myocardial infarction,and all-cause mortality.The secondary outcomes included acute kidney injury and sepsis.Odds ratio(OR)with 95%CI was pooled.RESULTS Thirteen studies with 85,596 patients were included.Compared to non-SGLT2i use,SGLT2i treatment was associated with lower risks of incident HF(OR=0.51,95%CI:0.32-0.79,P=0.003),HF exacerbation(OR=0.74,95%CI:0.63-0.87,P<0.001),AF/AFL(OR=0.67,95%CI:0.55-0.82,P<0.001),myocardial infarction(OR=0.61,95%CI:0.41-0.90,P=0.01),and all-cause mortality(OR=0.44,95%CI:0.28-0.69,P<0.001),but not for HF hospitalization(OR=0.58,95%CI:0.22-1.55,P=0.28).As for safety outcomes,SGLT2i use was associated with lower risks of acute kidney injury(OR=0.68,95%CI:0.57-0.81,P<0.001)and sepsis(OR=0.32,95%CI:0.23-0.44,P<0.001).CONCLUSIONS SGLT2i were associated with lower risks of incident HF,HF exacerbation,AF/AFL,myocardial infarction,allcause mortality,acute kidney injury,and sepsis in cancer patients.
文摘Measuring cardiorespiratory fitness(CRF)is an important predictor of morbidity and mortality in epidemiological studies and clinical settings.1 However,the feasibility of measuring maximal CRF is low due to the time,equipment,and expertise needed to conduct laboratory cardiopulmonary exercise testing(CPET)to determine the maximal rate of oxygen uptake(VO2max)as an objective measure of CRF.Alternatively,indirect estimates of CRF have been applied by measuring maximal duration on treadmill or cycle ergometer tests,2,3 extrapolating maximal CRF from workload or heart rate during submaximal fitness tests,4,5 and using non-exercise algorithms to estimate CRF from an individual’s age,sex,body mass,and physical activity habits.6 It is assumed that objectively measured VO2max is superior to extrapolated and estimated values due to errors associated with the estimated values;7,8 however,until Singh et al.9 newly released article in the Journal of Sport and Health Science,the comparability of these methods in identifying risks for all-cause and cardiovascular disease(CVD)mortality was unknown.

文摘As a mathematical analysis method,fractal analysis can be used to quantitatively describe irregular shapes with self-similar or self-affine properties.Fractal analysis has been used to characterize the shapes of metal materials at various scales and dimensions.Conventional methods make it difficult to quantitatively describe the relationship between the regular characteristics and properties of metal material surfaces and interfaces.However,fractal analysis can be used to quantitatively describe the shape characteristics of metal materials and to establish the quantitative relationships between the shape characteristics and various properties of metal materials.From the perspective of two-dimensional planes and three-dimensional curved surfaces,this paper reviews the current research status of the fractal analysis of metal precipitate interfaces,metal grain boundary interfaces,metal-deposited film surfaces,metal fracture surfaces,metal machined surfaces,and metal wear surfaces.The relationship between the fractal dimensions and properties of metal material surfaces and interfaces is summarized.Starting from three perspectives of fractal analysis,namely,research scope,image acquisition methods,and calculation methods,this paper identifies the direction of research on fractal analysis of metal material surfaces and interfaces that need to be developed.It is believed that revealing the deep influence mechanism between the fractal dimensions and properties of metal material surfaces and interfaces will be the key research direction of the fractal analysis of metal materials in the future.

文摘Coconut(Cocos nucifera L.)is a key tropical economic tree valued for its fruit flavor,particularly 2-acetyl-1-pyrroline(2AP),a vital aroma metabolite.To enhance high-aromatic coconut breeding efforts,it is essential to deeply understand the hereditary factors governing the production of 2AP.In this study,a genome-wide association analysis identifies 32 loci that exhibit significant associations with 2AP content based on single nucleotide polymorphism(SNP)variations from 168 aromatic coconut germplasm resources.Transcriptome analysis then pinpoints 22 candidate genes near significant loci involved in 2AP metabolism.Proteins encoded by these genes are involved in amino acid metabolism,glycolysis,and secondary metabolism.Among these,Asparagine synthetase coding gene ASN1,Gamma-glutamylcysteine synthetase coding gene GSH1,and UbiA prenyltransferase coding gene UBIA are enriched in the linkage region constructed by significant locus Chr04_61490504.In particular,the SNP mutation of CnASN1 leads to amino acid changes in the functional region of the coding protein,potentially resulting in differences in 2AP content among haplotype populations.Identifying variations in related candidate genes,particularly the gene CnASN1,provides molecular markers closely associated with 2AP synthesis for coconut breeding and offers further insights into the metabolic mechanisms of 2AP.

文摘The predominant causal agent of poplar leaf blight is the pathogenic fungus Alternaria alternata (Fr.) Keissl., which exhibits host specificity toward Populus species. To elucidate the molecular response mechanisms of A. alternata under fludioxonil fungicide stress, the fungus was cultured at the half-maximal effective concentration (EC₅₀) of fludioxonil. Transcriptomic and metabolomic profiles were analyzed using mycelia harvested under these conditions. Comparative analysis revealed 1,001 differentially expressed genes (DEGs) in the resistant strain (RS) relative to the wild-type strain (WT), comprising 628 upregulated and 373 downregulated genes. Concurrently, 524 differentially accumulated metabolites (DAMs) were identified, with 336 upregulated and 188 downregulated metabolites. KEGG pathway enrichment demonstrated pronounced upregulation in glycerophospholipid metabolism, α-linolenic acid metabolism, nucleic acid biosynthesis, and glycosylation processes. Conversely, arachidonic acid and galactose metabolism pathways were suppressed. Significant downregulation was observed in phosphatidylinositol signaling, aflatoxin biosynthesis, and cutin/suberin/wax biosynthesis pathways. Transcriptomic profiling further indicated that upregulated DEGs were predominantly associated with amino sugar/nucleotide sugar metabolism, ABC transporters, aflatoxin biosynthesis, and purine metabolism, while downregulated DEGs were enriched in N-glycan biosynthesis, endoplasmic reticulum protein processing, steroid biosynthesis, and riboflavin metabolism. Fludioxonil exerted substantial inhibitory effects on fungal growth, pathogenicity, and metabolic activity. Mechanistically, A. alternata counteracted fungicide-induced stress through modulation of its antioxidant defense system. This integrative multi-omics study delineates the dynamic gene expression and metabolic reprogramming in A. alternata under fludioxonil exposure, providing novel insights into potential molecular targets and informing the development of next-generation fungicidal strategies for phytopathogen control.
文摘[Objectives]To evaluate the impact of nasal insulin administration on postoperative delirium(POD)through meta-analysis.[Methods]The Cochrane Library,PubMed,Embase,Web of Science,China National Knowledge Infrastructure(CNKI),Wanfang Database,and China Science and Technology Journal Database(CSTJ)were systematically searched for relevant literature published prior to February 27,2025.Literature screening and data extraction were conducted by two independent researchers in accordance with predetermined inclusion and exclusion criteria.The primary observation indicator was the incidence of POD across various treatment populations.The risk ratio for the primary outcome was calculated using the Mantel-Haenszel method.The secondary outcomes included the adverse effects associated with insulin treatment,which encompassed the glycemic variability indices,the incidence of nasal irritation symptoms following administration,hypoglycemic reactions,and insulin allergic reactions.The study protocol was registered on PROSPERO(CRD420250607492)before data extraction.[Results]A total of five randomized controlled trials involving 357 patients were included in the analysis.In the adult population undergoing surgical procedures,the administration of insulin via nasal delivery was found to significantly reduce the incidence of POD[RR=0.35,95%CI(0.23-0.53),P<0.001].The results of the subgroup analysis indicated that there were notable differences in the effectiveness of various doses of insulin administered nasally in preventing POD.Specifically,both the 20 U dose group[RR=0.45,95%CI:(0.29,0.70),P<0.001]and the 30 U dose group[RR=0.01,95%CI:(0.03,0.42),P<0.001]showed a significantly lower incidence of POD compared to the control group,with statistically significant conclusions.Conversely,the 40 U dose group[RR=0.47,95%CI:(0.17,1.34),P=0.16]yielded no statistically significant difference.Furthermore,the efficacy in preventing POD was found to be greater in the 30 U dose group compared to the 20 U dose group.Additionally,two cases of hypoglycemic reactions and increased nasal irritation symptom scores were reported in the 40 U dose group across the entire study population(P<0.05),suggesting potential adverse risks associated with this dosage.[Conclusions]The nasal administration of insulin significantly decreases the incidence of POD at a specific dosage,with optimal efficacy and high safety observed at a dosage of 30 U.
文摘BACKGROUND Hepatocellular carcinoma(HCC)is among the most aggressive primary liver cancers,leading to significant global mortality.While early diagnosis improves prognosis,treatment decisions,particularly between surgical resection and radiofrequency ablation(RFA),remain controversial.AIM To clarify this issue using sentiment analysis of medical literature alongside a meta-analysis of overall survival(OS).METHODS We included studies comparing liver resection and RFA,excluding case reports,editorials,and studies without relevant outcomes.A systematic search in PubMed and Web of Science identified 197 studies.Abstracts underwent sentiment analysis using Python’s Natural Language Toolkit library,categorizing them as favoring resection,ablation,or neutral.We also performed a meta-analysis using a random-effects model on 11 studies reporting hazard ratios(HRs)for OS.RESULTS Sentiment analysis revealed that 75.1%of abstracts were neutral,14.2%favored resection,and 10.7%favored RFA.The meta-analysis showed a significant survival advantage for liver resection,with a pooled HR of 0.5924(95%confidence interval:0.540-0.649).Heterogeneity was moderate(I²=39.98%).Despite the meta-analysis demonstrating clear survival benefits of liver resection,most abstracts maintained a neutral stance.This discrepancy highlights potential biases or hesitancy in drawing definitive conclusions.CONCLUSION The study emphasizes the need for clinicians to prioritize robust statistical evidence over narrative impressions.Liver resection remains the preferred treatment for HCC in eligible patients.

文摘Alzheimer’s dementia(AD)and type 2 diabetes(T2D)are interrelated global public health problems,and the current epidemics of both AD and T2D are insulin resistance diseases.Thus,AD and T2D may share common risk factors such as an unhealthy diet,lifestyle,and obesity.Meat products is an important part of the diet of consumers worldwide.This systematic review and meta-analysis aims to assess and estimate the effect of meat products consumption on AD and T2D in humans.Web of Science,MEDLINE,PubMed,Cochrane Library,and Embase were searched from January 2012 to April 2024.29 articles reported 32 cohort studies with 1785769 subjects,with 3546 AD cases and 91092 T2D cases that met the inclusion criteria and were included in our analysis.Consumption of various meat products increased the risk of T2D(hazard ratios(HR)=1.19,95%confidence intervals(CI):1.13−1.26,P=0.000;I2=88.5%),consumption of smoked,grilled/roasted and fried meat products was more likely to induce T2D(HR=1.24,95%CI:1.18−1.30,P=0.000;I2=76.1%),but was borderline significant for the risk of AD(HR=1.11,95%CI:0.98−1.25,P=0.094;I2=58.8%),with consumption of mainly livestock and poultry products increasing the risk(HR=1.21,95%CI:1.03−1.42,P=0.017;I2=66.8%).The association between meat products consumption and AD risk was influenced by meat type and sample size,while the risk of T2D was influenced by meat type,follow-up and sex.A daily intake of 27,123 and 170 g of livestock products increased the risk of T2D by 10%,51%and 70%respectively,whereas the risk of T2D was reduced when the intake of various meat products was less than 23 g/day.

文摘Metal foils have emerged as one of the promising materials for anode-free batteries due to their high energy density and scalability in production.The unclear lithium plating/stripping kinetics of metal foil current collectors in anode-free batteries was addressed by using the non-destructive distribution of relaxation times(DRT)analysis to systematically investigate the lithium transport behavior of 14 metal foils and its correlation with electrochemical performance.By integrating energy-dispersive spectro scopy(EDS),cyclic voltammetry(CV),and galvanostatic testing,the exceptional properties of indium(In),tin(Sn),and silver(Ag)were revealed:the Li-In alloying reaction exhibits high reversibility,Li-Sn alloys demonstrate outstanding cycling stability,and the Li-Ag solid-solution mechanism provides an ideal lithium deposition interface on the silver substrate.The DRT separates the polarization internal resistance of lithium ions passing through the SEI layer(R_(sei),τ2)and the polarization internal resistance of lithium ions undergoing charge transfer reaction at the electrolyte/electrode interface(R_(ct),τ3)by decoupling the electrochemical impedance spectroscopy(EIS).For the first time,the correlation betweenτ2,τ3,and the cycle life/Coulombic efficiency of alloy/solid-solution metals was established,while non-alloy metals are not suitable for this method due to differences in lithium deposition mechanisms.This study not only illuminates the structure-property relationship governing the lithium kinetics of metal foil electrodes but also provides a novel non-destructive analytical strategy and theoretical guidance for the rational design of stable anodes in high-energy-density batteries,facilitating the efficient screening and optimization of anode-free battery.

文摘Serving as the initiating explosive devices between the propellant tank and the engines,metal-based rupture diaphragms are widely used in ramjet igniters owing to the advantages provided by their simple structure,small size,and low cost.However,the reliability of rupture pressure directly affects the success of engine ignition and rocket launch,which is mainly influenced by factors like material,structure,and residual thickness of the surface notch of the diaphragm.Among those,the geometry of the notch is easy to define and control when compared to the mechanical parameters of the ruptured diaphragm.Thus,to make the diaphragm rupture(1A30 Al)within the required pressure range(0.4 MPa±3.5%)with highly sensitive and reliability,we draw inspiration from the arthropod’s force-sensitive slit organ which encompasses curved microgrooves to design a Ω-shaped notch for the rupture diaphragm.Finite element analysis is used to study the relationship between the burst pressure and geometric dimension of theΩ-shaped and bioinspired microgroove.Based on that,metal-based rupture diaphragms are fabricated by femtosecond laser processing technology,followed by rupture tests.Experiment results demonstrate that the practical rupture pressure of the diaphragm is highly consistent with the finite element analysis results,which verifies the effectiveness of the bionic design.

文摘BACKGROUND Body composition analysis(BCA)is primarily used in the management of conditions such as obesity and endocrine disorders.However,its potential in providing nutritional guidance for patients with Alzheimer’s disease(AD)remains relatively unexplored.AIM To explore the clinical efficacy of BCA-based dietary nutrition scheme on bone metabolism in AD patients.METHODS This retrospective study included 96 patients with AD complicated by osteoporosis who were admitted to The Third Hospital of Quzhou between January 2023 and December 2024.Based on data from previous similar studies,the patients were randomly assigned to either a routine diet(RD)group(n=48)or a personalized nutrition(PN)group(n=48).The RD group received conventional dietary guidance,while the PN group received individualized diet intervention measures based on human BCA.The intervention period lasted for 12 weeks.Bone mineral density(BMD),body mass index(BMI),muscle mass,mineral content,osteocalcin,25-hydroxyvitamin D,procollagen type I N-terminal propeptide(PINP),beta C-terminal telopeptide of type I collagen(β-CTX),and serum calcium were measured and compared between the two groups before and 12 weeks after the intervention.RESULTS No significant differences were observed between groups in terms of age,sex,height,BMI,or other baseline data(P>0.05).In both groups,BMI did not show significant changes after the intervention(P>0.05),whereas muscle mass and mineral content were significantly increased(P<0.05).After the intervention,BMI in the PN group did not differ significantly from that of the RD group,but muscle mass and mineral content were significantly higher in the PN group(P<0.05).After the intervention,a higher proportion of patients in the PN group had a T score>-1 compared to the RD group(P<0.05).The mini-mental state examination(MMSE)score was similar in both groups before the intervention.However,12 weeks after the intervention,the MMSE score in the PN group was significantly higher than that in the RD group(P<0.05).In both groups,the MMSE score significantly increased 12 weeks post-intervention compared to pre-intervention levels(P<0.05).Before the intervention,the levels of osteocalcin,serum calcium,PINP,β-CTX,and 25-hydroxyvitamin D were not significantly different between the two groups(P>0.05).After 12 weeks of intervention,the PN group exhibited higher levels of osteocalcin,serum calcium,and 25-hydroxyvitamin D,as well as lower levels of PINP andβ-CTX,compared to the RD group(P<0.05).In both groups,osteocalcin,serum calcium,and 25-hydroxyvitamin D levels were significantly higher,while PINP andβ-CTX levels were significantly lower after 12 weeks of intervention compared to baseline(P<0.05).CONCLUSION The human BCA-based dietary nutrition regimen plays a crucial role in improving BMD and bone metabolism,with effects that surpass those of conventional nutrition strategies.The findings of this study provide strong evidence for the nutritional management of AD patients.
