Abstract Background: PRKAG2 syndrome typically manifests in adolescence and early adulthood, progressing with left ventricular hypertrophy, arrhythmias, and risk of sudden death. Findings of echocardiographic markers before clinical manifestation in children of patients affected by the disease can facilitate prevention strategies and therapeutic planning for this patient group. Objective: To identify the existence of echocardiographic findings that manifest early in children of parents affected by PRKAG2 syndrome, while they are still asymptomatic. Methods: In this cross-sectional observational study, 7 participants who were children of parents with established diagnosis of PRKAG2 syndrome, between the ages of 9 months and 12 years, with proven genetic diagnosis, underwent conventional and advanced echocardiography. Their findings were compared to those of a control group composed of 7 age- and sex-matched volunteers who were healthy from a cardiovascular point of view. P values < 0.05 were considered significant. Results: Conventional echocardiography showed statistically significantly higher values in the case group for left atrium, interventricular septum, left ventricular posterior wall, indexed ventricular mass, and relative wall thickness (p < 0.05). Global longitudinal systolic strain on 2-dimensional echocardiography did not show statistical significance between the case and control groups. None of the parameters on 3-dimensional echocardiography showed statistical significance between groups. Conclusion: Children diagnosed with PRKAG2 showed echocardiographic findings indicative of a tendency toward cardiac hypertrophy. Echocardiography can be a useful tool in the evaluation and follow-up of this patient group before the onset of clinical manifestations.

Abstract Objective To investigate the epidemiology of injury types among jiu-jitsu practitioners, as well as the incidence regarding different skill and experience levels, through the question: "What are the characteristics and prevalence of musculoskeletal injuries in Jiu-Jitsu practitioners?". Methods Since the beginning of the study, in August 2020, we conducted a search on the MEDLINE, LILACS, and SciELO electronic databases. We included cross-sectional studies published between 2018 and 2023 on the epidemiology of the types of injuries among jiu-jitsu practitioners that compared their incidence regarding different levels of ability and experience. Two independent researchers performed the data extraction and assessed the risk of bias. Results Seven studies were included. The common outcomes involved 2,847 jiu-jitsu practitioners. A high prevalence in the knee joint and chest and rib areas was reported. Considering the difference in experience level among the practitioners, we could observe that most of the individuals included were beginners. Among the age groups observed, male practitioners older than 30 years of age were the ones who presented the highest rate of musculoskeletal injury, especially during training sessions. Conclusion There is a high prevalence of musculoskeletal injuries among jiu-jitsu practitioners. The most affected anatomical segments are the knee joint, the chest, and the rib region, followed by the shoulder joint. The related factors change according to certain variables, being more common during training in male individuals over 30 years of age and beginners in the sport. jiujitsu jiu jitsu question What JiuJitsu Jiu Jitsu . practitioners?" study 2020 MEDLINE LILACS databases crosssectional cross sectional 201 202 bias 2847 2 847 2,84 reported observed 3 sessions region variables sport practitioners? 20 284 84 2,8 28 8 2,

Abstract The objective was to perform a spatial analysis of the hospital mortality rate (HMR) due to severe acute respiratory syndrome (SARS) attributed to COVID-19 among children and adolescents in Brazil from 2020 to 2021. A cluster method was used to group federal units (FUs) based on HMR. In 2020, clusters with high HMRs were formed by north/northeast FUs. In 2021, there was a reduction in HMR. Clusters with higher rates remained in the N/NE region. Regional differences were observed in the HMR. The findings may reflect social inequalities and access to hospital care, especially in the under 1-year-old age group due to the severity of the disease in this group.

Abstract: The aim of this study was to estimate genetic parameters and select superior mango genotypes using the mixed-models approach. The 16 genotypes, varieties and hybrid selections, were evaluated regarding physical and physical-chemical traits of the fruit using the REML/BLUP methodology. Mango fruit weight and pulp weight can be selected indirectly based on fruit length and diameter, which are more easily evaluated. The hybrids CPAC 26394, Lita, and Rosa 46 stand out in regard to fruit size. The genotypes R12P09, CPAC 2293, Roxa, Omega, Alfa, and Lita have better quality fruit than the Tommy Atkins variety that is widely used in commercial orchards. The Roxa variety has pulp with little or no fiber, a trait that is of great importance to consumers and for industrial processing. The genotypes Alfa, CPAC 5895, Ômega, R10P08, R12P09, R13P10, Rosa 2, Rosa 36, and Rosa 46 have pulp free of internal breakdown. The varieties and hybrid selections of mango show variability regarding fruit traits, and the REML/BLUP methodology is efficient for selection of genotypes with desirable fruit traits in mango.

Abstract Vegetative propagation methods of acerola cherry are important in standardizing orchards and fruit quality, and the cutting process has been investigated as a promising alternative. The present work aimed to propose the best combination of substrate and cutting type (herbaceous and semi-woody) to provide a greater root rate and seedling development. The trial was conducted in a greenhouse at the State University of Maranhão, in São Luís - MA under intermittent nebulization conditions. The cuttings with dimensions of 10 cm were treated with indole butyric acid (IBA) at a concentration of 2,000 mg L-1, and as substrate were used vermiculite (MV), Plantmax ® (PL) (commercial substrate based on decomposed pine bark), agricultural soil + tanned and sieved bovine manure (S + M) (50% + 50%, v / v); and vegetable soil (VS) composed of fresh soil with the remains of decomposed plants (leaves, stems, bark, and tree fern). The experiment was laid out in a randomized complete design in a 2 x 4 factorial arrangement (2 types of cuttings x 4 substrates) with eight replications with five cuttings per plot. At 60 days after the establishment of the trial, it was concluded that the best combination for rooting cuttings was vermiculite with herbaceous cuttings because they favor a higher rooting rate (95.0%). The alternative substrate composed of soil and tanned bovine manure provided promising results in the rate of rooting (72.5%), root formation, and vegetative development of the aerial part. quality semiwoody semi woody semi-woody Maranhão conditions 1 IBA (IBA 2000 000 2,00 L1, L1 L 1, L-1 MV, MV , (MV) PL (PL commercial bark bark) S M 50% 50 (50 v) VS (VS leaves, leaves (leaves stems fern. fern . fern) ( substrates plot 6 95.0%. 950 95.0% 95 0 (95.0%) 72.5%, 725 72.5% 72 5 (72.5%) formation part 200 00 2,0 L- (MV (5 95.0 9 (95.0% 72.5 7 (72.5% 20 2, 95.

ABSTRACT We present a case report detailing the successful phacoemulsification surgery with artificial iris implantation for two individuals with oculocutaneous albinism. These women suffered from cataracts, resulting in reduced visual acuity and heightened photophobia due to iris pigmentary epithelium deficiency. The patients underwent phacoemulsification along with prosthetic artificial iris implantation into the posterior chamber. This intervention resulted in improved visual acuity, reduced photophobia and glare, and an overall enhanced quality of life. Our report highlights two cases of successful phacoemulsification and artificial iris implantation in patients with oculocutaneous albinism and cataracts, leading to improved visual acuity, reduced photophobia, and enhanced quality of life. Notably, there are no prior records in South American literature of cataract surgery combined with artificial iris implantation for oculocutaneous albinism patients up to the time of this publication. cataracts deficiency chamber glare life Notably publication

ABSTRACT Objectives: Here, we investigated the effects of hyperventilation on acute lung injury (ALI) in spontaneously breathing rats. Methods: Wistar rats were randomized to receive either intraperitoneal lipopolysaccharides (LPS) or saline, and intravenous infusion of NH4Cl (to induce metabolic acidosis and hyperventilation) or saline. Four groups were established: control-control (C-C), control-hyperventilation (C-HV), LPS-control (LPS-C), and LPS-hyperventilation (LPS-HV). Venous blood gases were collected before and after NH4Cl infusion and analyzed to confirm the presence of metabolic acidosis and hyperventilation. After euthanasia, lung injury was assessed using the ALI score, morphometric quantification of perivascular edema, neutrophil counts in the bronchoalveolar lavage, and mRNA expression of biological markers in the lung tissue. Results: Hyperventilation induced inflammatory lung injury in previously healthy lungs and exacerbated injuries previously induced by LPS (ALI score: C-C=0.14 [IQR 0.12; 0.14]; C-HV=0.36 [IQR 0.31; 0.37]; LPS-C=0.51 [IQR 0.50; 0.54]; LPS-HV=0.58 [IQR 0.56; 0.62]; p<0.01). Perivascular edema, neutrophil counts in bronchoalveolar lavage, and amphiregulin mRNA expression were higher in the LPS-HV group compared to the control group. Conclusions: Hyperventilation increased inflammatory injury in rats with ALI during spontaneous ventilation. These results suggest that the impact of vigorous spontaneous breathing efforts on worsening inflammatory lung injury warrants further investigation.

Abstract Food supplements commonly present nutritional quality, especially in plant-origin foods, contributing to the population's quality of life. The use of babassu mesocarp flour in the preparation of food supplements contributes to human nutrition as it is a nutritionally balanced food concerning carbohydrates, proteins, lipids, and minerals. Babassu fruits were collected in five municipalities in the state of Maranhão/Brazil, and the mesocarp was extracted to develop four food supplement formulations per municipality. Firstly, babassu mesocarp flour was prepared in a drying and sterilization process and, subsequently, the manufacturing process of the babassu coconut flour food supplement was added with natural soy extract. The samples were subjected to proximate composition analysis to determine the percentages of carbohydrates, lipids, proteins, moisture, lignin, and energy values (kcal/100 g). The study presented a product rich in carbohydrates (86%), protein values above 10% in the composition, and an average of 19% lipids, presenting a nutritional balance suitable for daily use by the population and even high-performance athletes. plantorigin plant origin foods populations s life proteins lipids minerals MaranhãoBrazil Maranhão Brazil Maranhão/Brazil municipality Firstly subsequently extract moisture lignin kcal/100 kcal100 kcal 100 (kcal/10 g. g . g) 86%, 86 86% , (86%) 10 19 highperformance high performance athletes kcal/10 kcal10 (kcal/1 8 (86% 1 kcal/1 kcal1 (kcal/ (86 kcal/ (kcal (8 (

Abstract This study explored the effects of L-PRF on pain, soft tissue healing, periodontal condition, and post-extraction bone repair of mandibular third molars (3Ms). A randomized, prospective, triple-blind, split-mouth clinical trial was conducted with 34 volunteers. Eligible patients were randomly allocated into two treatments: G1 (without L-PRF), G2 (alveoli filled with L-PRF), in which the removal of bilateral 3Ms was performed at the same surgical time. Outcomes were assessed according to a visual analogue scale (pain), soft tissue scoring system (wound healing), periodontal probing of mandibular second molar. Bone repair was determined by volumetric analysis (ITK-SNAP software) and fractal analysis (ImageJ software). An intention-to-treat approach to Statistical analysis was used. L-PRF reduced pain in the 7-day postoperative follow-up (p = 0.019) and not only improved soft tissue healing after 1 month of follow-up (p = 0.021), but also probing depth (distal face) in 3 months postoperatively (p = 0.011). Significant alveolar reduction occurred in 3 months after surgery in both treatments (p < 0.05), however, this was more significant in G1 (p = 0.016). The fractal dimension showed no statistical differences. L-PRF improved postoperative clinical parameters of pain, soft tissue healing, and periodontal condition, suggesting that it has a beneficial effect on preserving the alveolar ridge and accelerating the initial repair process.

The industry's principal objective is to comprehend the optimal application of each metal alloy in terms of corrosion resistance. A key focus lies in exploring alternative approaches to address this corrosive process in a manner that is both sustainable and economically feasible. The major strategy to mitigate this contest involves the utilization of inhibitors. However, it is imperative to note that certain inhibitors pose environmental risks. This study explores the effect of the addition of protic ionic liquids (PILs) on the corrosion of carbon steel (A36) in a saline solution (3.5 wt% NaCl), considering variations in pH and temperature. It focuses on understanding the effects of pH and temperature on the PILs' ability to protect the steel surface. Notably, changes in pH do not affect the protective capacity of the inhibitors. Efficiency values exceeding 72% were achieved under both acidic conditions tested. The study reveals two scenarios: At 40 °C, the PILs effectively protect the steel, with an efficiency of approximately 74% at concentrations of 500 and 1000 ppm. However, at 60 °C, efficiency decreases notably, reaching a maximum of 51% at a concentration of 500 ppm. Afterward, to evaluate the protective effectiveness of these compounds, gravimetric and electrochemical impedance spectroscopy (EIS) serve as the main methods, accompanied by optical and atomic force microscopy (AFM) for evaluating the surface. In electrochemical tests, PILs 1 and 2 exhibit superior efficiency, with film formation, while PILs 3 to 6 demonstrate comparatively lower values. industrys industry s resistance feasible However risks (PILs A36 (A36 3.5 35 5 (3. wt NaCl, NaCl , NaCl) surface Notably 72 tested scenarios 4 C °C 74 50 100 ppm notably 51 Afterward compounds EIS (EIS methods AFM (AFM tests formation A3 (A3 3.

Abstract Concrete presents complex behavior, being a difficult material to define the ideal proportion of its constituents. To overcome this challenge, many mix design methods have been developed over time. However, most of these methods do not consider durability parameters during the procedure. Thus, the objective of this article is to present a mix design method for concrete, with properties of workability (slump rating from 50 mm to 220 mm), axial compressive strength (class of 25MPa to 55MPa), and durability as response parameters. From the application of the proposed method, it was possible to create mix design and performance diagrams. It was noticed that all concretes fell into the pre-established consistency class and presented axial compressive strength results close to the predetermined values.

RESUMO A síndrome corticobasal (SCB) é uma causa rara de demência e compreende combinações variadas de sinais subcorticais (parkinsonismo acinético-rígido, distonia ou mioclonias) com sinais corticais (apraxia, mão alienígena ou déficit sensorial cortical), geralmente assimétricos. Nosso objetivo foi relatar e comparar as apresentações clínica e de neuroimagem de dois pacientes com diagnóstico de SCB. Enquanto o caso 1 apresentava afasia grave não fluente associada a apraxia leve e rigidez de membros, o caso 2 exibia comprometimento cognitivo mais posterior, com padrão de linguagem distinto, erros visuoespaciais e heminegligência. O FDG PET teve papel significativo no diagnóstico, sugerindo, no primeiro caso, degeneração corticobasal e, no segundo, padrão Alzheimer. A SCB tem sido amplamente estudada com o advento de novos métodos in vivo, como o FDG PET cerebral. Estudos que aprofundem a heterogeneidade fenotípica e de biomarcadores da SCB serão de grande importância para melhor classificação, prognóstico e tratamento da doença. (SCB parkinsonismo acinéticorígido, acinéticorígido acinético rígido, rígido acinético-rígido mioclonias apraxia, (apraxia cortical, cortical , cortical) assimétricos membros posterior distinto heminegligência sugerindo segundo Alzheimer vivo cerebral classificação doença

ABSTRACT Corticobasal syndrome (CBS) is a rare cause of dementia and comprises varied combinations of subcortical signs (akinetic-rigid parkinsonism, dystonia, or myoclonus) with cortical signs (apraxia, alien hand or cortical sensory deficit), usually asymmetric. We aimed to report and compare the clinical and neuroimaging presentation of two patients diagnosed with CBS. While case 1 had severe non-fluent aphasia associated with mild apraxia and limb rigidity, case 2 had a more posterior cognitive impairment, with a different language pattern associated with marked visuospatial errors and hemineglect. FDG PET played a significant role in diagnosis, suggesting, in the first case, corticobasal degeneration and, in the second, Alzheimer's disease pattern.
