Every year, around the world, between 250,000 and 500,000 people suffer a spinal cord injury(SCI). SCI is a devastating medical condition that arises from trauma or disease-induced damage to the spinal cord, disrupting the neural connections that allow communication between the brain and the rest of the body, which results in varying degrees of motor and sensory impairment. Disconnection in the spinal tracts is an irreversible condition owing to the poor capacity for spontaneous axonal regeneration in the affected neurons. 展开更多

Races using kitefoil and windfoil surfboards have been in the Olympic Games for the first time in Paris 2024,signalling their relevance in sailing sports.However,the dynamics of these devices is yet not well understood,in particular the influence on the hydrodynamic forces and moments of the distance of the foil to the free surface.Considering this,the present paper documents an experimental investigation in which forces and torque produced,under uniform flow,by a full-scale state-of-the-art hydrofoil(suitable both for kitesurf and windsurf)were measured.A range of velocities,angles of attack,and submergences were tested,leading to Froude numbers based on submergence with maximum values around five,a typical range in actual sailing conditions.From these tests,formulae for the hydrodynamic coefficients have been proposed.They can be used for developing Velocity Prediction Programs(VPP)for this kind of craft,a necessary tool to plan racing configurations and to analyze their racing performance.With the aim of making the experimental data useful for benchmarking numerical models and for future research on related topics such as foil ventilation and transition to turbulence,the specimen’s 3D file is provided as supplementary material to this paper. 展开更多

During the use of robotics in applications such as antiterrorism or combat,a motion-constrained pursuer vehicle,such as a Dubins unmanned surface vehicle(USV),must get close enough(within a prescribed zero or positive distance)to a moving target as quickly as possible,resulting in the extended minimum-time intercept problem(EMTIP).Existing research has primarily focused on the zero-distance intercept problem,MTIP,establishing the necessary or sufficient conditions for MTIP optimality,and utilizing analytic algorithms,such as root-finding algorithms,to calculate the optimal solutions.However,these approaches depend heavily on the properties of the analytic algorithm,making them inapplicable when problem settings change,such as in the case of a positive effective range or complicated target motions outside uniform rectilinear motion.In this study,an approach employing a high-accuracy and quality-guaranteed mixed-integer piecewise-linear program(QG-PWL)is proposed for the EMTIP.This program can accommodate different effective interception ranges and complicated target motions(variable velocity or complicated trajectories).The high accuracy and quality guarantees of QG-PWL originate from elegant strategies such as piecewise linearization and other developed operation strategies.The approximate error in the intercept path length is proved to be bounded to h^(2)/(4√2),where h is the piecewise length. 展开更多

Effective treatment methods for stroke,a common cerebrovascular disease with a high mortality rate,are still being sought.Exosome therapy,a form of acellular therapy,has demonstrated promising efficacy in various diseases in animal models;however,there is currently insufficient evidence to guide the clinical application of exosome in patients with stroke.This article reviews the progress of exosome applications in stroke treatment.It aims to elucidate the significant potential value of exosomes in stroke therapy and provide a reference for their clinical translation.At present,many studies on exosome-based therapies for stroke are actively underway.Regarding preclinical research,exosomes,as bioactive substances with diverse sources,currently favor stem cells as their origin.Due to their high plasticity,exosomes can be effectively modified through various physical,chemical,and genetic engineering methods to enhance their efficacy.In animal models of stroke,exosome therapy can reduce neuroinflammatory responses,alleviate oxidative stress damage,and inhibit programmed cell death.Additionally,exosomes can promote angiogenesis,repair and regenerate damaged white matter fiber bundles,and facilitate the migration and differentiation of neural stem cells,aiding the repair process.We also summarize new directions for the application of exosomes,specifically the exosome intervention through the ventricular-meningeal lymphatic system.The review findings suggest that the treatment paradigm for stroke is poised for transformation. 展开更多

Different forms of programmed cell death have been described to participate in the degeneration of dopaminergic neurons in Parkinson’s disease(PD).Given the critical role that disturbance of mitochondrial homeostasis plays in the pathogenesis of PD,apoptosis can be reasonably considered as one of the cell death pathways involved in neuronal loss(Schon and Przedborski,2011).Multiple lines of evidence support that proposal such as the observations in postmortem human brain samples of PD patients including mitochondrial complex I deficiency,reactive oxygen species generation,and oxidative damage to lipids,proteins,and DNA,among others. 展开更多

Progressive photoreceptor cell death is one of the main pathological features of age-related macular degeneration and eventually leads to vision loss.Ferroptosis has been demonstrated to be associated with retinal degenerative diseases.However,the molecular mechanisms underlying ferroptosis and photoreceptor cell death in age-related macular degeneration remain largely unexplored.Bioinformatics and biochemical analyses in this study revealed xC^(–),solute carrier family 7 member 11-regulated ferroptosis as the predominant pathological process of photoreceptor cell degeneration in a light-induced dry age-related macular degeneration mouse model.This process involves the nuclear factor-erythroid factor 2-related factor 2-solute carrier family 7 member 11-glutathione peroxidase 4 signaling pathway,through which cystine depletion,iron ion accumulation,and enhanced lipid peroxidation ultimately lead to photoreceptor cell death and subsequent visual function impairment.We demonstrated that solute carrier family 7 member 11 overexpression blocked this process by inhibiting oxidative stress in vitro and in vivo.Conversely,solute carrier family 7 member 11 knockdown or the solute carrier family 7 member 11 inhibitor sulfasalazine and ferroptosis-inducing agent erastin aggravated H_(2)O_(2)-induced ferroptosis of 661W cells.These findings indicate solute carrier family 7 member 11 may be a potential therapeutic target for patients with retinal degenerative diseases including age-related macular degeneration. 展开更多

Background Supplementation of choline chloride in culture medium programs the preimplantation bovine embryo to increase weaning weight of the resultant calf.Here,it was hypothesized that similar programming actions of choline can be induced by feeding rumen-protected choline(RPC)to beef cows during the periconceptional period.Results A preliminary experiment was conducted to determine changes in circulating concentrations of choline and its metabolites after RPC supplementation.Suckled beef cows were individually fed 0,30,60,and 90 g of RPC(i.e.,0,8.6,17.3 and 25.9 g choline chloride)and blood samples were collected at random times after feeding.There were no differences in plasma concentrations of choline or its metabolites between groups.In the second experiment,effects of feeding 60 g/d RPC from d-1 to 7 relative to timed artificial insemination were examined for suckled beef cows.Feeding RPC did not affect pregnancy or calving rates,pregnancy losses,plasma concentrations of pregnancy-associated glycoproteins,gestation length or calf birth weight.Calves from RPC fed dams were lighter than control calves at~118 days of age(range 75–150;age included in the statistical model)and at weaning at~248 days of age.There was no effect of treatment on hip height at~118 days of age although there was a trend for RPC calves to be shorter at weaning.Weight/height ratio was lower for RPC than control at both 118 and 248 days of age.Treatment did not affect testis weight at~118 days of age.Conclusions Supplementation of RPC during the periconceptional period programmed development to alter calf phenotype in the postnatal period.The net result,reduced body weight,was the opposite of the phenotype caused by the addition of choline to embryo culture medium. 展开更多

Focusing on the reform of talent training under the background of the integration of production and education in vocational education,this paper takes Xinjiang Vocational College of Physical Education as the research object.Based on the field survey data of 36 enterprises and public institutions in Urumqi and Kashgar regions from May to June 2023,it systematically analyzes the demand characteristics,ability requirements of employers for sports professionals,and their feedback on current training programs.The research finds that employers have a strong demand for talent in sports training and physical education,and generally attach importance to professional skills and comprehensive quality,but they believe that graduates need pre-job training to be competent for the positions.Most units recognize the existing curriculum structure and support school-enterprise cooperation.Accordingly,this paper proposes that we should take moral education as the fundamental,optimize professional positioning,reconstruct the modular curriculum system,strengthen practical teaching and the integration of“courses,certificates,competitions,and posts,”deepen the coordination of production and education,and build a new employment-oriented training mechanism for high-quality sports technical and skilled talents. 展开更多

Severe aortic stenosis has increased exponentially as a result of the aging of the population.Transcatheter aortic valve replacement(TAVR)procedures increase by 20%-30%per year in Spain.Referred patients are increasingly older,have comorbidities,and frailty.TAVR cardiac rehabilitation(CR)programs significantly improve both functional capacity and quality of life of patients.However,there are no guidelines on how to carry out them and few elderly patients are referred to CR.Furthermore,mortality in women who undergo TAVR is higher than in men and even fewer are referred to CR programs.Multidisciplinary patient care,including comorbidities and frailty,is essential.It is necessary to ensure exquisite continuity of care during TAVR,CR,and the rest of the patient's life.Telerehabilitation could be an option in some lower-risk patients to include more patients in CR programs after TAVR,given the high demand.This article reviews the evidence on why CR should be performed in post-TAVR patients and proposes a practical and novel approach to the care process and the recommended aspects and components of the CR program. 展开更多

A two-phase monadic approach is presented for monadically slicing programs with procedures. In the monadic slice algorithm for interprocedural programs, phase 1 initializes the slice table of formal parameters in a procedure with the given labels, and then captures the callees' influence on callers when analyzing call statements. Phase 2 captures the callees' dependence on callers by replacing all given labels appearing in the corresponding sets of formal parameters. By the introduction of given labels, this slice method can obtain similar summary information in system-dependence-graph(SDG)-based algorithms for addressing the calling-context problem. With the use of the slice monad transformer, this monadic slicing approach achieves a high level of modularity and flexibility. It shows that the monadic interprocedural algorithm has less complexity and it is not less precise than SDG algorithms. 展开更多

To solve the problems that the exception handling code is hard to test and maintain and that it affects the robustness and reliability of software, a method for evaluating the exception handling of programs is presented. The exception propagation graph (EPG) that describes the large programs with exception handling constructs is proposed by simplifying the control flow graph and it is applied to a case to verify its validity. According to the EPG, the exception handling code that never executes is identified; the points that are the most critical to controlling exception propagation are found; and the irrational exception handling code is corrected. The constructing algorithm for the EPG is given; thus, this provides a basis for automatically constructing the EPG and automatically correcting the irrational exception handling code. 展开更多
