Background: Patients with rheumatic diseases have profound alterations in the immune system as a result of underlying diseases and the treatments used, which increases the risk of occurrence and severity of infections, including enteroparasitosis. The current treatment for rheumatoid arthritis involves immunosuppressive therapies powerfully needed for screening infectious processes. The prevalence of parasitic infections in rheumatoid arthritis patients is not currently documented in literature. The objective of the current study was to determine the prevalence of parasitic diseases in a population with RA. Methods: We collected demographic and socioeconomic data from 67 patients at the Hospital Universitário de Brasília from July 2015 to April 2016. All patients underwent a parasitological examination of their stool and multiple variables were analyzed using Poisson regression method. Results: The mean age of patients was 53.9 years. They were predominantly in women (94%) and caucasian (47.8%). The mean disease duration was 9.2 years and most patients had the disease in remission or light activity. The prevalence of parasitic infections in these patients was 11.9%, all cases being that of protozoa of the following species: Endolimax nana, Entamoeba histolytica and Entamoeba coli. The final multivariate analysis indicated that the presence of disease had a significant statistical relationship between the presence of enteroparasitosis and rheumatoid arthritis with no fatigue by VAS (p = 0.0488) and best current health index by VAS (p = 0.0012). Conclusion: This study indicates that the prevalence of enteroparasitoses in a population with Rheumatoid Arthritis was 11.9% and all cases were found of protozoa. 展开更多

Non-human primates(NHPs)serve as necessary reservoir hosts of parasites that create diseases to human.A close interaction between human and NHP can make a pathway for transmission of zoonotic diseases.To prevent zoonotic infection of zoo keepers,park visitors as well as keeping the captive NHPs in healthy state,it is necessary to carry out regular parasitological examination and treatment.A total of 72 fecal samples of Olive Baboon(n=39)and Common Langur(n=33)irrespective of their age and sex were collected from two zoological gardens of Bangladesh.Eggs and oocysts of seven gastrointestinal(GI)parasites were observed and identified in samples of both host species.The prevalence of GI parasites recorded was 100%.In case of Olive Baboon,the protozoan prevalence was higher(53.83%)than that of helminths,but opposite scenario was seen in case of Common Langur.Besides,higher intensity of coccidian oocysts in both hosts was recorded in the study. 展开更多

Esophageal stricture refers to a pathological narrowing of the esophageal lumen,causing dysphagia and impairing the patient's quality of life.There are various etiologies including esophageal malignancy,peptic injury,caustic ingestion,postsurgical anastomosis,radiation therapy,and inflammatory disorders such as eosinophilic esophagitis.The primary goal in managing esophageal strictures is to relieve dysphagia by maintaining luminal patency.Endoscopic dilation remains the mainstay of treatment for most benign strictures,with either bougie or balloon dilators.For patients who develop refractory or recurrent strictures that are difficult to manage with dilation alone,adjunctive therapies like intralesional steroid injections,topical or injected mitomycin C,incisional therapy,stent placement,and finally surgery may enhance outcomes and reduce the frequency of repeat procedures.The present review focuses on the basics of dilation and adjunctive strategies for the management of esophageal stricture. 展开更多

Rocky outcrops function as island-like environmental filters and pivotal ecological refuges for local and regional biodiversity,with their inherent topographic and microclimatic dynamics directly shaping vegetation composition and distribution across slopes.This study inventoried the flora of a rocky outcrop slope within Brazil's Caatinga biome,a seasonally dry tropical forest,to analyze species distribution patterns and their relationship with microtopographic conditions.The slope was stratified into base,middle and top segments according to slope gradient,with specimens collected over seven months of field expeditions,followed by taxonomic processing to compile a floristic inventory.The survey documented 60 species,53 genera,and 28 families,with Fabaceae,Euphorbiaceae,and Malvaceae emerging as the most representative families;herbaceous species dominated,followed by trees and shrubs.Species richness declined along the topographic gradient as altitude increased,with 43%of flora comprising species widespread across Brazilian biomes and 20%endemic to the Caatinga.Variations in species distribution across slope positions suggest that topographic heterogeneity may drive distinct pedological and microclimatic conditions,directly influencing vegetation dynamics in rock outcrops.These findings underscore the role of microtopography in structuring plant communities in harsh environments. 展开更多

The application of different coatings on solar photovoltaic(PV)panels can be an efficient solution to increase performance and further mitigate the emission of greenhouse gases.This study uses the Life Cycle Assessment(LCA)methodology and the environmental payback concept to analyze the effects of the application of a nano-silica coating on a solar PV system installed in the Brazilian Northeast.Firstly,an uncoated reference 16.4 MW PV system is designed,and the detailed inventory is presented(PV panels,supporting structure,inverters,junction boxes,cables,transportation,maintenance and operation-including the replacement of equipment).The results of the LCA quantify the greenhouse gas emissions associated with the PV system.Electricity production is estimated by technical and local climate data.Subsequently,the environmental payback time of the system is calculated,which is the time required for the PV system to offset the emissions associated with system manufacturing,operation,and disposal.This is the first Brazilian study to verify the effects of a self-cleaning coating on a solar PV system throughout its lifetime,compared to the uncoated(reference system).The original photovoltaic system emitted 22,534,773 kg CO_(2)-eq,with an environmental payback of 5 years and 1 day.When the self-cleaning coating is applied,the emissions are 21,511,317 kg CO_(2)-eq(almost 5%lower)with a payback of 4 years,1 month and 26 days.The application of self-cleaning coatings reduces the required area for installation(due to increased efficiency),and not only reduces emissions but is also aligned with global sustainability targets and contributes to the concept of sustainable and intelligent cities. 展开更多

Rolling noise is produced by vibration of the wheels and track,induced by their combined surface roughness.It is important to know the relative contributions of the different sources,as this affects noise control strategies as well as acceptance testing of new rolling stock.Three different techniques are described that aim to use pass-by measurements to separate the wheel and track components of rolling noise.One is based on the TWINS model,which is tuned to measured track vibration.The second is based on the advanced transfer path analysis method,which provides an entirely experimental assessment.The third is based on the pass-by analysis method in combination with static vibroacoustic transfer functions which are obtained using a reciprocity method.The development of these methods is described and comparisons between them are presented using the results from three experimental measurement campaigns.These covered a metro train,a regional train and a high-speed train at a range of speeds.The various methods agree reasonably well in terms of overall trends,with moderate agreement in the mid-frequency region,and less consistent results at low and high frequency. 展开更多

In this editorial,we discuss the recent article by Regassa et al,published in the World Journal of Diabetes,which highlights the potential role of platelet indices(PI)in predicting poor glucoregulation in patients with type 2 diabetes mellitus(T2DM).Given the high morbidity and mortality associated with T2DM,there is a constant need to find new and accessible methods for predicting and treating individuals with this condition.The pathophysiology of T2DM involves systemic inflammation,metabolic dysfunction,and an increased risk of vascular injury,which are commonly associated with the development of microvascular and macrovascular complications,such as cardiovascular diseases and neuropathies.The link between these complications and T2DM requires further elucidation but may be explained by prolonged exposure to high glycemic levels and increased advanced glycation end products.PI might play an important role in determining whether some individuals are prone to poor glucoregulation.Recent evidence encourages the scientific efforts to demonstrate the consistency of this role and its applicability in monitoring glucoregulation,underscoring the importance of the study by Regassa et al. 展开更多

The Northeast region is the main producer of guava in Brazil,generating employment and income.However,water availability means that producer’s resort to using water with high salinity,which harms plant development,especially during the seedling formation phase.The adoption of techniques that mitigate the deleterious effect of salinity is increasingly necessary,such as the use of elicitors such as ascorbic acid.The purpose of this study was to analyze the morphophysiology of guava seedlings under saline and ascorbic acid levels.The study was carried out by applying treatments composed of five saline levels(SL=0.3;1.3;2.3;3.3 and 4.3 dS m^(-1))and four levels of ascorbic acid—AA(0,200,400,and 600 mg L^(-1)),in a 5×4 factorial arrangement,adopting a randomized block design.Gas exchange and growth of guava seedlings are limited from 0.3 dS m^(-1).Using 400 mg L^(-1)of AA reduces damage from salinity on stomatal conductance,transpiration,and net assimilation rate up to the estimated SL of 1.80 dS m^(-1).In contrast,AA level 412 mg L^(-1)increased instantaneous water use efficiency up to the salinity of 2.3 dS m^(-1).AA level of 600 mg L^(-1)attenuated salt stress effects on leaf area and height/stem diameter ratio up to SL of 2.05 dS m^(-1).The number of leaves and the absolute and relative growth rates were stimulated by AA under the lowest saline level. 展开更多

Force control merged with motion control represent the fundamental low level requirements for the most complex tasks to be performed by any robot.In particular,robust motion and force controllers allow robots to deal with real-world uncertainties among other disturbances.In this paper,an admittance-based force controller using the Active Disturbance Rejection Control approach is proposed,which allows to perform robot force control without a force sensor.In addition,a theoretical synthesis of the control law including an extended state observer for the estimation of the robot–surface force interaction and their formal stability analysis is presented.The validation of the proposal is depicted by numerical simulations using the dynamical model of a two degrees of freedom robot manipulator,for both a constant and a time-varying force control tasks with an unknown curved surface,while considering joint measurement noise and force sensors noise and an external disturbance force. 展开更多

Developing high-efficient flame-retardant coatings is crucial for fire safety polymer and battery fields.Traditional intumescent coatings and ceramifiable coatings struggle to provide immediate and prolonged protection simultaneously,which limits the applicability.To address this,an innovative bi-layered coating with organic/nano-inorganic additives is inspired by differential response behaviors,enabling relay response effect with both fast-acting and extended protection.Specifically,two layers function continuously in the form of a relay.With a mere 320 microns,the bi-layered coating withstands fire temperatures of up to 1400℃for at least 900 s.Consequently,the coating effective prevented burn through in aluminum plates and glass fabric-reinforced epoxy resin,which otherwise were burned through in 135 and 173 s,respectively.Meanwhile,the bi-layered coating suppressed the formation and decomposition of solid interface layer in lithium soft-package batteries,leading to prolonged electrochemical stability and fire safety.Additionally,the bi-layered coating with a fast response endows polyurethane foam with rapid self-extinguishing,preventing ignition even under exposure to strong fire of 1400℃.Shortly,our work offers new insights into the design and development of thin,high-performance,and multi-application flame-retardant coatings. 展开更多

Advancing 3D magnesium(Mg)development beyond current limitations requires controlling Mg alloy degradation in pre-designed,low-dimension architectures.This study reveals a mechanistic switch in the corrosion behavior of Mg alloy(3.6%Al,0.8%Zn)diamond lattice structures,induced by plasma nanosynthesis(400 eV Ar^(+)ions,fluence 1×10^(17) ions/cm^(2)).Plasma treatment of the Mg alloy increases surface Mg from 1.5%to 14.5%,enhances carbonate formation,and generates a nanostructured surface with a Mg carbonate layer over an oxide/hydroxide layer.In vitro and in vivo analyses over 8 wk demonstrate how this treatment fundamentally alters the degradation process and stability of these 3D architectures.While untreated samples initially formed a protective film that subsequently diminished,DPNS-treated samples demonstrated an inverse corrosion behavior.X-ray photoelectron spectroscopy(XPS)and electrochemical impedance spectroscopy(EIS)confirmed the presence of a stable,protective layer composed of magnesium oxide,magnesium hydroxide,and magnesium carbonate on the DPNS-treated surfaces.After 14 days,the DPNS-treated sample exhibited a more positive corrosion potential(-0.69 V versus-1.36 V)and a marginally lower current density(0.73 mA/cm^(2)compared to 0.75 mA/c^(2))relative to the control.This protective layer,combined with modified surface topology,initiated a core-to-periphery degradation pattern that maintained structural integrity for up to 8 wk post-implantation.These findings support the conclusion that the DPNS-treated scaffold demonstrates sustained improved corrosion resistance over time compared to the untreated control.Micro-CT revealed plasma-treated samples retained larger struts(504.9±95.3μm at 8 wk)and formed larger H_(2) pockets extending 14.2 mm from the implant center,versus 4.9 mm in controls.This corrosion behavior switch enhances stability but risks pore clogging,offering insights for tailoring Mg alloy degradation and H_(2) evolution in 3D architectures for biomedical applications. 展开更多

Purpose – The vibration of the rails is a significant source of railway rolling noise, often forming the dominantcomponent of noise in the important frequency region between 400 and 2000 Hz. The purpose of the paper is toinvestigate the influence of the ground profile and the presence of the train body on the sound radiation fromthe rail.Design/methodology/approach – Two-dimensional boundary element calculations are used, in which therail vibration is the source. The ground profile and various different shapes of train body are introduced in themodel, and results are observed in terms of sound power and sound pressure. Comparisons are also made withvibro-acoustic measurements performed with and without a train present.Findings – The sound radiated by the rail in the absence of the train body is strongly attenuated by shieldingdue to the ballast shoulder. When the train body is present, the sound from the vertical rail motion is reflectedback down toward the track where it is partly absorbed by the ballast. Nevertheless, the sound pressure at thetrackside is increased by typically 0–5 dB. For the lateral vibration of the rail, the effects are much smaller. Oncethe sound power is known, the sound pressure with the train present can be approximated reasonably well withsimple line source directivities.Originality/value – Numerical models used to predict the sound radiation from railway rails have generallyneglected the influence of the ground profile and reflections from the underside of the train body on the soundpower and directivity of the rail. These effects are studied in a systematic way including comparisons with measurements. 展开更多

Background:Pain associated with cancer is one of the greatest causes of reduced quality of life in patients.Acupuncture is one of the treatments used to address this issue,with the great advantage of having little or no side effects,especially when compared with pharmacological pain-killers.Objective:The aim of this systematic review and meta-analysis was to evaluate the current evidence regarding the efficacy of acupuncture for cancer pain.Search strategy:Six electronic databases(PubMed,EBSCO,Cochrane Library,Scielo,b-On and Scopus)were searched for relevant articles about pain relief in cancer patients from their beginning until 2022using MeSH terms such as“acupuncture,”“electroacupuncture,”“ear acupuncture,”“acupuncture analgesia,”“oncological pain,”and“cancer pain.”Inclusion criteria:Studies included were randomized controlled trials(RCTs)where acupuncture was compared with no treatment,placebo acupuncture or usual care.Data extraction and analysis:Three independent reviewers participated in data extraction and evaluation of risk of bias,and a meta-analysis was conducted.The primary outcome was pain intensity,measured with the visual analog scale,numeric rating scale,or brief pain inventory.Secondary outcomes also assessed were quality of life,functionality,xerostomia,pain interference,and analgesic consumption.Results were expressed as standardized mean difference(SMD)with 95%confidence interval(CI).Results:Sixteen RCTs with a total of 1124 participants were included in the meta-analysis,with the majority of the studies presenting a low or unclear risk of bias.Acupuncture was more effective in reducing pain than no treatment(SMD=–0.90,95%CI[–1.68,–0.12]),sham acupuncture(SMD=–1.10,95%CI[–1.59,–0.61])or usual care(SMD=–1.16,95%CI[–1.38,–0.93]).Conclusion:The results of this study suggest that acupuncture may be an effective intervention to reduce pain associated with cancer.Despite some limitations due to the low quality and small sample size of some included studies,as well as the different types and stages of cancer,acupuncture might provide an effective and safe treatment to reduce cancer pain. 展开更多

Surface modification of graphite anode with electroactive matters has been proven of a more practical strategy in enhancing the performance of Li-ion batteries than exploring alternative novel anode materials.Herein,rutile TiNbO_(4-x) nanoparticles with a tunnel structure are employed as multifunctional decoration substances in combination with a carbon coating layer to improve the rate and cycle properties of mesocarbon microbeads(MCMBs).As compared to pristine MCMB,the Li^(+)diffusion coefficients of the composite anodes are enhanced due to the synergistic effect of TiNbO_(4-x)@C.Meanwhile,the overcharge and voltage polarization of the composite anodes at high rate are obviously minimized due to the current sharing effect of the high-potential TiNbO_(4-x).Moreover,the amorphous Li_(y)TiNbO_(4-x) converted from TiNbO_(4-x) in the initial lithiation process can deliver pseudocapacitive capacity to the composite anodes from the second cycle.All of these functions of TiNbO_(4-x)@Ccoating layer have directly contributed to the improved rate and cycle performance of the MCMB/TiNbO_(4-x)@C composite anodes.The one containing 12.0 wt%TiNbO_(4-x) exhibits a high reversible specific capacity of 118 m Ah·g^(-1)at 10C(1C=372 m A·g^(-1)),together with a high capacity retention of 90.9%after 300 cycles at 3C,which are all much superior to those of pristine MCMB. 展开更多

The aim of this work was to improve the thermal conductivity and electromagnetic shielding of the leakage proof phase change materials(PCMs),in which a polyrotaxane(PLR)was used as a support material to encapsulate PEG 1k or PEG 6k and MXene as multi-functional filler.The PCMs can be processed conveniently by a hot press and the PEG 1k containing samples showed excellent flexibility.We conducted a systematic evaluation of the phase transition behavior of the material,thermal conductivity and electromagnetic shielding performance tests.Notably,the PCMs achieved a high enthalpy values(123.9–159.6 J/g).The PCMs exhibited an increase of 44.3%,and 137.5%in thermal conductivity values with higher MXene content(5 wt%)for PLR-PEG6k and PLR-PEG1k,respectively,and show high shape stability and no leakage during and after phase transition.The introduction of MXene can significantly improve the electromagnetic shielding performance of PCM composites.Typically,higher conductive samples(samples which contain high MXene contents)offer a higher EMI SE shielding,reaching a maximum of 4.67 dB at 5.6 GHz for PLR-1K-MX5.These improvements solve the main problems of organic PEG based PCMs,thus making PLR-PEG-MXene based PCMs good candidates for thermoregulators of both solid-state disks and smart phone.It is worth pointing out that the sample PLR-1k-MX5 can decrease 4.3C of the reference temperature during cellphone running.Moreover,the temperature of the protecting sheet in the simulated solid state disk with PCM was significantly lower(showing a decreasing of 7.9℃)compared with the blank sample. 展开更多

Research on fires at the wildland-urban inter-face(WUI)has generated significant insights and advance-ments across various fields of study.Environmental,agri-culture,and social sciences have played prominent roles in understanding the impacts of fires in the environment,in protecting communities,and addressing management challenges.This study aimed to create a database using a text mining technique for global researchers interested in WUI-projects and highlighting the interest of countries in this field.Author’s-Keywords analysis emphasized the dominance of fire science-related terms,especially related to WUI,and identified keyword clusters related to the WUI fire-risk-assessment-system-“exposure”,“danger”,and“vulnerability”within wildfire research.Trends over the past decade showcase shifting research interests with a growing focus on WUI fires,while regional variations highlighted that the“exposure”keyword cluster received greater atten-tion in the southern Europe and South America.However,vulnerability keywords have relatively a lower representation across all regions.The analysis underscores the interdisci-plinary nature of WUI research and emphasizes the need for targeted approaches to address the unique challenges of the wildland-urban interface.Overall,this study provides valu-able insights for researchers and serves as a foundation for further collaboration in this field through the understanding of the trends over recent years and in different regions. 展开更多

Background:The benefits of exercise are well known;however,many of the underlying molecular mechanisms are not fully understood.Skeletal muscle secretes myokines,which mediate muscleorgan crosstalk.Myokines regulate satellite-cell proliferation and migration,inflammatory cascade,insulin secretion,angiogenesis,fatty oxidation,and cancer suppression.To date,the effects of different exercise modes(namely,aerobic and resistance exercise)on myokine response remain to be elucidated.This is crucial considering the clinical implementation of exercise to enhance general health and wellbeing and as a medical treatment.Methods:A systematic search was undertaken in PubMed,MEDLINE,CINAHL,Embase,SPORTDiscus,andWeb of Science in April 2023.Eligible studies examining the effects of a single bout of exercise on interleukin15(IL-15),irisin,secreted protein acidic and rich in cysteine(SPARC),oncostatinM(OSM),and decorin were included.A random-effects meta-analysis was also undertaken to quantify the magnitude of change.Results:Sixty-two studies were included(n=1193).Overall,exercise appeared to induce small to large increases in myokine expression,with effects observed immediately after to 60 min post-exercise,although these were mostly not statistically significant.Both aerobic and resistance exercise resulted in changes in myokine levels,without any significant difference between training modes,and with the magnitude of change differing across myokines.Myokine levels returned to baseline levels within 180 min to 24 h post-exercise.However,owing to potential sources of heterogeneity,most changes were not statistically significant,indicating that precise conclusions cannot be drawn.Conclusion:Knowledge is limited but expanding with respect to the impact of overall and specific effects of exercise on myokine expression at different time points in the systemic circulation.Further research is required to investigate the effects of different exercise modes at multiple time points on myokine response. 展开更多

Pancreatic fluid collections(PFCs)result from injury to the pancreas from acute or chronic pancreatitis,surgery,or trauma.Management of these collections has evolved over the last 2 decades.The choice of interventions includes percu-taneous,endoscopic,minimally invasive surgery,or a combined approach.Endoscopic drainage is the drainage of PFCs by creating an artificial communication between the collection and gastrointestinal lumen that is maintained by placing a stent across the fistulous tract.In this editorial,we endeavored to update the current status of endoscopic ultrasound-guided drainage of PFCs. 展开更多

Effective calcium(Ca)management is crucial for optimizing oil palm cultivation and enhancing crop yield.This study aimed to gain insights into the dynamics of Ca concentration,accumulation,exportation,immobilization,and recycling in various oil palm organs relative to plant age.The experiment was conducted at the Agropalma enterprise site in the northeastern region of Para State,Brazil,evaluating seven plant age treatments:2,3,4,5,6,7,and 8 years old.Employing a completely randomized design with four replications.The results demonstrated an age-related increase in Ca concentration in petioles,rachis,arrows,male inflorescences,peduncles,and fruits.Furthermore,Ca accumulation exhibited an upward trend in all organs with progressing plant age.Notably,the study revealed an enhanced Ca use efficiency across all plant organs in correlation with the age of oil palm cultivation.These findings underscore the dynamic nutritional demands of oil palm,influencing Ca immobilization,cycling,and export throughout its developmental stages. 展开更多
