Apolipoprotein E(APOE) genotypes and their corresponding protein(Apo E) isoforms may influence the biophysical properties of the cell membrane lipid bilayer. However, the role of APOE in central nervous system pathophysiology extended beyond its lipid transport function. In the present review article, we analyzed the links existing between APOE genotypes and the neurobiology of neuropsychiatric symptoms in neurodegenerative and vascular diseases. APOE genotypes(APOE ε2, APOE ε3, and APOE ε4) were implicated in common mechanisms underlying a wide spectrum of neurodegenerative diseases, including sporadic Alzheimer's disease, synucleinopathies such as Parkinson's disease and Lewy body disease, stroke, and traumatic brain injury. These shared pathways often involved neuroinflammation, abnormal protein accumulation, or responses to acute detrimental events. Across these conditions, APOE variants are believed to contribute to the modulation of inflammatory responses, the regulation of amyloid and tau pathology, as well as the clearance of proteins such as α-synuclein. The bidirectional interactions among Apo E, amyloid and mitochondrial metabolism, immunomodulatory effects, neuronal repair, and remodeling underscored the complexity of Apo E's role in neuropsychiatric symptoms associated with these conditions since from early phases of cognitive impairment such as mild cognitive impairment and mild behavioral impairment. Besides Apo E-specific isoforms' link to increased neuropsychiatric symptoms in Alzheimer's disease(depression, psychosis, aberrant motor behaviors, and anxiety, not apathy), the APOE ε4 genotype was also considered a significant genetic risk factor for Lewy body disease and its worse cognitive outcomes. Conversely, the APOE ε2 variant has been observed not to exert a protective effect equally in all neurodegenerative diseases. Specifically, in Lewy body disease, this variant may delay disease onset, paralleling its protective role in Alzheimer's disease, although its role in frontotemporal dementia is uncertain. The APOE ε4 genotype has been associated with adverse cognitive outcomes across other various neurodegenerative conditions. In Parkinson's disease, the APOE ε4 allele significantly impacted cognitive performance, increasing the risk of developing dementia, even in cases of pure synucleinopathies with minimal co-pathology from Alzheimer's disease. Similarly, in traumatic brain injury, recovery rates varied, with APOE ε4 carriers demonstrating a greater risk of poor long-term cognitive outcomes and elevated levels of neuropsychiatric symptoms. Furthermore, APOE ε4 influenced the age of onset and severity of stroke, as well as the likelihood of developing stroke-associated dementia, potentially due to its role in compromising endothelial integrity and promoting blood–brain barrier dysfunction.展开更多

文摘Objective The rising prevalence of childhood obesity is closely associated with suboptimal dietary patterns.To address this public health concern,we conducted a comprehensive study to examine the association between coarse cereals consumption and body fat percentage(BFP)in Chinese children and adolescents.Methods The study included 48,305 children aged 6–17 years from 28 districts/counties in 14 provinces across seven regions of China(24,152 girls and 24,153 boys).BFP was examined using bioelectrical impedance analysis in the early morning.Coarse cereals consumption was assessed using a Food Frequency Questionnaire and categorized into three groups:0 g/1,000 kcal per day,0–10 g/1,000kcal per day,and>10 g/1,000 kcal per day(daily consumption of coarse cereals×1,000/total energy consumption).Quantile regression model was used to analyze the association between coarse cereals and BFP,adjusting for potential confounders such as age,pubertal development stage,urban/rural and regional factors,total daily dietary energy consumption,sedentary time,moderate-to-high physical activity,household income,parental education,and consumption of other foods.Results Boys aged 6–10,11–14,and 15–17 years had median daily coarse cereals consumptions of6.6 g,7.1 g,and 5.7 g,with BFP of 19.6%,19.5%,and 17.5%(all P<0.05).Girls in the same age groups showed consumption of 7.1 g,8.4 g,and 6.7 g,with BFP of 20.3%,26.4%,and 31.0%(all P<0.05).The quantile regression results for boys showed that daily consumption of coarse cereals was significantly correlated with their BFP in the 0.15,0.25,and 0.50 quartiles,with regression coefficients of-0.257,-0.221,and-0.330,respectively,after adjusting for potential confounders(P<0.05).For girls,there was a significant correlation with PBF at the 0.05,0.15,0.25,0.50,0.75,and 0.85 quartiles,with regression coefficients of-0.258,-0.366,-0.372,-0.431,-0.472,and-0.503(P<0.05 for all).Conclusions Coarse cereals consumption among Chinese children and adolescents remains relatively low.Higher consumption was inversely associated with BFP in children aged 6–17 years.Future interventional studies should assess how increased coarse cereals consumption prevents childhood obesity.
文摘Selecting the initial antipsychotic dose is a high-impact decision in acute schizophrenia.A randomized study found that starting lurasidone at 80 mg/day for 1 week(then flexible titration)produced earlier reductions in Positive and Negative Syndrome Scale positive symptoms than 40 mg/day,without higher discontinuations for adverse events or a metabolic penalty over 6 weeks.These data support an individualized approach:Start at 80 mg/day when rapid control of positive symptoms or agitation is needed and tolerance permits;start at 40 mg/day when akathisia risk or patient preference argues for caution,with a planned day-7 review for up-titration.The open-label design,dose convergence after week 1,and the lack of stratified randomization limit attribution of longer-term advantages to starting dose.Even so,the trial reframes initial dose as a modifiable lever for the early course rather than a one-size-fits-all rule and warrants confirmation in larger,double-blind randomized trials.

文摘Objective Previous studies link lower body mass index(BMI)with increased obsessive-compulsive disorder(OCD)risk,yet other body mass indicators may be more etioloically relevant.We dissected the causal association between body fat mass(FM)and OCD.Methods Summary statistics from genome-wide association studies of European ancestry were utilized to conduct two-sample Mendelian randomization analysis.Heterogeneity,horizontal pleiotropy,and sensitivity analyses were performed to assess the robustness.Results The inverse variance weighting method demonstrated that a genetically predicted decrease in FM was causally associated with an increased OCD risk[odds ratio(OR)=0.680,95%confidence interval(CI):0.528–0.875,P=0.003].Similar estimates were obtained using the weighted median approach(OR=0.633,95%CI:0.438–0.915,P=0.015).Each standard deviation increases in genetically predicted body fat percentage corresponded to a reduced OCD risk(OR=0.638,95%CI:0.455–0.896,P=0.009).The sensitivity analysis confirmed the robustness of these findings with no outlier instrument variables identified.Conclusion The negative causal association between FM and the risk of OCD suggests that the prevention or treatment of mental disorders should include not only the control of BMI but also fat distribution and body composition.

文摘Detecting biomarkers in body fluids by optical lateral flow immune assay(LFIA) technology provides rapid access to disease information for early diagnosis.LFIA is based on an antigen-antibody reaction and is rapidly becoming the preferred choice of physicians and patients for point-of-care testing due to its simplicity,cost-effectiveness,and rapid detection.Observing the optical signal change from the colloidal gold of the traditional LFIA strip has been widely applied for various biomarkers detection in body fluids.Despite the significant progress,rapid real-time detection of color changes in the colloidal gold by the naked eye still faces many limitations,such as large errors and the inability to quantify and accurately detect.New optical LFIA strip technology has emerged in recent years to extend its application scenarios for achieving quantitative detection such as fluorescence,afterglow,and chemiluminescence.Herein,we summarized the development of optical LFIA technology from single to hyphenated optical signals for biomarkers detection in body fluids from invasive and non-invasive sources.Moreover,the challenge and outlook of optical LFIA strip technology are highlighted to inspire the designing of next-generation diagnostic platforms.

文摘Electron–hole(e–h)recombination is a fundamental process that governs energy dissipation and device efficiency in semiconductors.In two-dimensional(2D)materials,the formation of tightly bound excitons makes exciton-mediated e–h recombination the dominant decay pathway.In this work,nonradiative e–h recombination within excitons in monolayer MoS2 is investigated using first-principles simulations that combine nonadiabatic molecular dynamics with𝐺𝑊and real-time Bethe–Salpeter equation(BSE)propagation.A two-step process is identified:rapid intervalley redistribution induced by exchange interaction,followed by slower phonon-assisted recombination facilitated by exciton binding.By selectively removing the screened Coulomb and exchange terms from the BSE Hamiltonian,their respective contributions are disentangled—exchange interaction is found to increase the number of accessible recombination pathways,while binding reduces the excitation energy and enhances nonradiative decay.A reduction in recombination lifetime by over an order of magnitude is observed due to the excitonic many-body effects.These findings provide microscopic insights for understanding and tuning exciton lifetimes in 2D transition-metal dichalcogenides.
文摘Complex genetic relationships between neurodegenerative disorders and neuropsychiatric symptoms have been shown, suggesting shared pathogenic mechanisms and emphasizing the potential for developing common therapeutic targets. Apolipoprotein E(APOE) genotypes and their corresponding protein(Apo E) isoforms may influence the biophysical properties of the cell membrane lipid bilayer. However, the role of APOE in central nervous system pathophysiology extended beyond its lipid transport function. In the present review article, we analyzed the links existing between APOE genotypes and the neurobiology of neuropsychiatric symptoms in neurodegenerative and vascular diseases. APOE genotypes(APOE ε2, APOE ε3, and APOE ε4) were implicated in common mechanisms underlying a wide spectrum of neurodegenerative diseases, including sporadic Alzheimer's disease, synucleinopathies such as Parkinson's disease and Lewy body disease, stroke, and traumatic brain injury. These shared pathways often involved neuroinflammation, abnormal protein accumulation, or responses to acute detrimental events. Across these conditions, APOE variants are believed to contribute to the modulation of inflammatory responses, the regulation of amyloid and tau pathology, as well as the clearance of proteins such as α-synuclein. The bidirectional interactions among Apo E, amyloid and mitochondrial metabolism, immunomodulatory effects, neuronal repair, and remodeling underscored the complexity of Apo E's role in neuropsychiatric symptoms associated with these conditions since from early phases of cognitive impairment such as mild cognitive impairment and mild behavioral impairment. Besides Apo E-specific isoforms' link to increased neuropsychiatric symptoms in Alzheimer's disease(depression, psychosis, aberrant motor behaviors, and anxiety, not apathy), the APOE ε4 genotype was also considered a significant genetic risk factor for Lewy body disease and its worse cognitive outcomes. Conversely, the APOE ε2 variant has been observed not to exert a protective effect equally in all neurodegenerative diseases. Specifically, in Lewy body disease, this variant may delay disease onset, paralleling its protective role in Alzheimer's disease, although its role in frontotemporal dementia is uncertain. The APOE ε4 genotype has been associated with adverse cognitive outcomes across other various neurodegenerative conditions. In Parkinson's disease, the APOE ε4 allele significantly impacted cognitive performance, increasing the risk of developing dementia, even in cases of pure synucleinopathies with minimal co-pathology from Alzheimer's disease. Similarly, in traumatic brain injury, recovery rates varied, with APOE ε4 carriers demonstrating a greater risk of poor long-term cognitive outcomes and elevated levels of neuropsychiatric symptoms. Furthermore, APOE ε4 influenced the age of onset and severity of stroke, as well as the likelihood of developing stroke-associated dementia, potentially due to its role in compromising endothelial integrity and promoting blood–brain barrier dysfunction.

文摘The inability to access brain tissue has greatly hindered our ability to study and care for individuals suffering from psychiatric and neurological conditions.Critics have questioned efforts to develop peripheral blood biomarkers in neurological and psychiatric disorders based on the assertion that disease pathology is limited to the brain.The discovery that all tissues,including the brain,release extracellular vesicles(Raposo and Stoorvogel,2013)and cell free DNAs(Chan et al.,2013)into various body fluids has provided a potential way to measure activity from inaccessible tissues like the central nervous system(CNS)and has given rise to the term“liquid biopsy.”The development of liquid biopsies that can diagnose and predict the course of psychiatric and neurological disorders would be transformative.The ability to predict episodic events such as mania,depression,and risk for suicide would be particularly useful for psychiatric care as it would enable the development of interventions that prevent mortality and improve outcomes.Additionally,biomarkers that are informative about drug response and aid in treatment decisions would be a significant advance in psychiatric care as it would prevent patients from having to endure multiple courses of ineffective treatments and side effects.

文摘The existence of the"stomach-knee axis"and the potential independent association between"Helicobacter pylori(Hp)infection and knee osteoarthritis(KOA)"have been substantiated through multiple lines of evidence,including epidemiological studies of the"stomach-knee axis",investigations into the pathological mechanisms linking"Hp infection and arthritis",as well as research on co-treatment drugs and the anti-inflammatory mechanisms relevant to"gastritis and arthritis".The investigation into"stomach and knee joint treatment"is grounded in the concept that the"stomach-knee axis"aligns with the"combined bi of body constituents and zang organs"theory.Clinical cases have demonstrated that therapeutic strategies of"stomach and knee joint treatment"can mitigate KOA damage by modulating the"stomach-knee axis"and eradicating Hp infection in the stomach.This study aims to contribute novel insights into the cross-system treatment of KOA.Further investigation into the"stomach-knee axis"may yield innovative strategies for the prevention and management of KOA,potentially through the eradication of Hp.

文摘With the gradual advancement of research methods and technologies,various biological processes have been identified as playing roles in the pathogenesis of neurodegenerative diseases.However,current descriptions of these biological processes do not fully explain the onset,progression,and development of these conditions.Therefore,exploration of the pathogenesis of neurodegenerative diseases remains a valuable area of research.This review summarizes the potential common pathogeneses of Alzheimer’s disease,Parkinson’s disease,amyotrophic lateral sclerosis,Huntington’s disease,frontotemporal lobar dementia,and Lewy body disease.Research findings have indicated that several common biological processes,including aging,genetic factors,progressive neuronal dysfunction,neuronal death and apoptosis,protein misfolding and aggregation,neuroinflammation,mitochondrial dysfunction,axonal transport defects,and gut microbiota dysbiosis,are involved in the pathogenesis of these six neurodegenerative diseases.Based on current information derived from diverse areas of research,these biological processes may form complex pathogenic networks that lead to distinctive types of neuronal death in neurodegenerative diseases.Furthermore,promoting the regeneration of damaged neurons may be achievable through the repair of affected neural cells if the underlying pathogenesis can be prevented or reversed.Hence,these potential common biological processes may represent only very small,limited elements within numerous intricate pathogenic networks associated with neurodegenerative diseases.In clinical treatment,interfering with any single biological process has proven insufficient to completely halt the progression of neurodegenerative diseases.Therefore,future research on the pathogenesis of neurodegenerative diseases should focus on uncovering the complex pathogenic networks,rather than isolating individual biological processes.Based on this,therapies that aim to block or reverse various targets involved in the potential pathogenic mechanisms of neurodegenerative diseases may be promising directions,as current treatment methods that focus on halting a single pathogenic factor have not achieved satisfactory efficacy.

文摘Electrical energy can be harvested from the rotational kinetic energy of moving bodies,consisting of both mechanical and kinetic energy as a potential power source through electromagnetic induction,similar to wind energy applications.In industries,rotational bodies are commonly present in operations,yet this kinetic energy remains untapped.This research explores the energy generation characteristics of two rotational body types,disk-shaped and cylinder-shaped under specific experimental setups.The hardware setup included a direct current(DC)motor driver,power supply,DC generator,mechanical support,and load resistance,while the software setup involved automation testing tools and data logging.Electromagnetic induction was used to harvest energy,and experiments were conducted at room temperature(25℃)with controlled variables like speed and friction.Results showed the disk-shaped body exhibited higher energy efficiency than the cylinder-shaped body,largely due to lower mechanical losses.The disk required only two bearings,while the cylinder required four,resulting in lower bearing losses for the disk.Additionally,the disk experienced only air friction,whereas the cylinder encountered friction from a soft,uneven rubber material,increasing surface contact losses.Under a 40 W resistive load,the disk demonstrated a 17.1%energy loss due to mechanical friction,achieving up to 15.55 J of recycled energy.Conversely,the cylinder body experienced a 48.05%energy loss,delivering only 51.95%of energy to the load.These insights suggest significant potential for designing efficient energy recycling systems in industrial settings,particularly in manufacturing and processing industries where rotational machinery is prevalent.Despite its lower energy density,this system could be beneficially integrated with energy storage solutions,enhancing sustainability in industrial practices.

文摘Objectives This study aimed to develop and preliminarily assess the quality of a Mindfulness Breast Care(MBC)App to reduce body image distress and stigma among breast cancer survivors(BCSs).Methods The development process of the MBC App involved:1)establishing a research group;2)determining of the content of the MBC App based on Mindfulness-Based Cognitive Therapy and 3)technical exploitation and maintenance.A mixed-methods study was conducted.We selected ten BCSs by a convenience sampling method.After using the APP for three months,five assessed the quality using the Mobile App Rating Scale:User Version(uMARS)and another five were interviewed for process evaluation.Results The MBC App was developed with three modules:1)Library to provide health education information on body image,stigma,mindfulness,recovery and etc;2)Mindfulness Yoga to offer 12 Hatha yoga videos for daily practice;and 3)Mindfulness Practices to have 12 sessions of mindfulness videoconferences.Based on the uMARS data,the MBC App received high ratings for functionality(4.10±0.34),aesthetics(3.93±0.55),information quality(4.10±0.72),and perceived impact(4.03±0.96),as well as moderate ratings for engagement(3.72±0.94)and subjective quality(3.87±0.77).Participants indicated that the MBC App provided reliable knowledge,information,and emotional support.Recommendations from participants included categorizing knowledge in the Library Module,recording videoconferences of mindfulness practice,and adding discussion sessions in the videoconference.Afterward,we optimized the MBC App to enhance the user experience accordingly.Conclusions The MBC App offers online mindfulness interventions specifically for BCSs in China.The preliminary quality assessment indicates that the MBC App may be a promising tool for delivering mindfulness interventions to BCSs.
文摘Hepatocellular carcinoma(HCC)remains a leading cause of cancer-related mortality worldwide,necessitating innovative treatment strategies.Surgical resection and liver transplantation continue to be the gold standards for early-stage HCC;however,advances in imaging and minimally invasive techniques have improved patient selection and outcomes.Additionally,the emergence of targeted therapies and immunotherapy has transformed the treatment landscape for advanced HCC.This review highlights the efficacy of agents such as tyrosine kinase inhibitors,alongside emerging options like immune checkpoint inhibitors,which have shown promise in clinical trials.Furthermore,the role of locoregional therapies,including ablation in the setting of combined treatment,transar-terial chemoembolization and transarterial radioembolization with flow catheters,cone-beam computed tomo-graphy and 4D navigation guidance,is examined in the context of bridging therapies for patients awaiting surgical intervention.The integration of multidisciplinary care approaches and personalized treatment plans is crucial for optimizing outcomes.Future directions for HCC treatment are discussed,including the potential of novel biomarkers in prognosis and treatment response.This comprehensive overview aims to equip clinicians with the latest insights and foster collaborative efforts to improve HCC patient management and survival rates.
文摘Impairments on body function,activities of daily living(ADL)and cognition are common after stroke.Eccentric resistance training(ERT)may be implemented to improve them.The primary objectives were to evaluate whether ERT improves body function,ADL and cognition after stroke.The secondary objectives were to evaluate whether ERT improves strength,gait,quality of life,and self-perceived health.Seven electronic databases were searched:Cochrane Central Register of Controlled Trials,Cochrane Stroke Group Trials Register,PubMed,Epistemonikos,Embase,SPORTDiscus,and WHO International Clinical Trials Registry Platform.Last search was run in December 2023,including studies since 2012.Selection criteria were studies with stroke participants of both sexes,aged 18 or more,with an intervention based on ERT.Accepted languages were English,Spanish or French.First search was done in pairs.Authors removed duplicate studies and those which did not meet inclusion criteria through title and abstracts.Finally,all authors,independently,screened the final search results and extracted data.Of 68 records identified,15 were eligible and 6 were finally included(with moderate risk of bias),analyzing 159 participants.Body function(4 interventions,n=84),gait(4 interventions,n=115)and strength(3 interventions,n?78)showed significantly better results when ERT was performed.Meta-analysis could not be done because of the few studies and their heterogeneity.This review provided low-moderate quality evidence suggesting that ERT might be effective at improving body function,strength,and gait after stroke.Besides,no harm was documented,and it was well-accepted.
