Background: Transcutaneous electrical acupoint stimulation (TEAS) improves autonomic balance and reduces oxidative stress in subjects with chronic diseases, that decreases the risk of low-grade chronic inflammatory diseases, including cardiovascular diseases. However, these beneficial effects have never been demonstrated in healthy subjects. Objectives: To evaluate the acute effects of TEAS on autonomic balance and oxidative stress of healthy subjects. Methods: A randomized clinical trial was conducted with male healthy subjects (18-30 years old), randomly allocated to control (no intervention; n = 14), placebo (placebo intervention; n = 14) and TEAS group (at PC5 and PC6 acupoints; n = 13). The protocol consisted of accommodation (20 min), intervention (40 min), and recovery (30 min) periods. The acute effects of TEAS on hemodynamics were studied through measurements of heart rate, blood pressure and double product; on the autonomic nervous system by assessing heart rate variability; and on oxidative stress by quantifying reactive oxygen species in saliva samples, collected at the end of each period. Results: TEAS increased heart rate and double-product compared to control and placebo groups (p < 0.01). Moreover, TEAS increased sympathetic and reduced parasympathetic tonus, increasing the sympathovagal balance compared to the control and placebo groups. However, TEAS exerted no effect on oxidative stress in saliva samples. Conclusion: In healthy subjects, TEAS at PC5 and PC6 acupoints acutely improved autonomic balance, increasing sympathetic and reducing parasympathetic tonus, reflecting little improvement on hemodynamic responses. Whether it could be used as a cardioprotective strategy remains uncertain since it exerted no effect on oxidative stress.

Pereira Daniela Figueiredo Corrêa,Parron Fernandes Karen Barros,Aguiar Andreo Fernando,Casonatto Juliano 대한뇌신경재활학회 2024 뇌신경재활 Vol.17 No.1

Patients experiencing a cerebrovascular event are vulnerable to declining nutritional status, hindering rehabilitation. This study aims to analyze the association between malnutrition risk and hospital rehabilitation indicators in ischemic stroke sur vivors (ISS). This analytical study examined medical records of 160 adult patients (69.3 ± 13 years). Undernutrition risk (UR; independent variable) and rehabilitation indicators (dependent variables) like hospital stay, clinical outcome, functionality, stroke severity, food intake, mobility (bedridden), mechanical ventilation, and enteral nutrition were assessed. Data were dichotomized, and the chi-square test identified associations (p ≤ 0.05), followed by Poisson regression for prevalence ratios. Patients at UR had 2-fold higher risk of death (95% confidence inter val [CI], 0.99–4.79), 1.8-fold higher risk of high stroke severity (95% CI, 1.06–3.11), 76% higher chance of being bedridden (95% CI, 1.28–2.44), and 3-fold higher risk of mechanical ventilation (95% CI, 1.20–9.52). UR in hospitalized ISS is associated with deteriorating rehabilitation indicators, including mobility, decreased food intake, mechanical ventilation use, and neurological deficit, indicating an increased mortality risk post-stroke

Rosana Martínez-Smit,Juan Fernando Aristizabal,Valfrido Antonio Pereira Filho 대한치과교정학회 2019 대한치과교정학회지 Vol.49 No.5

In this report, we describe the successful use of alternate rapid maxillary expansions and constrictions with a hybrid hyrax–mandibular miniplate combination and simultaneous orthodontic treatment for the management of severe Class III malocclusion due to maxillary hypoplasia in an 11-year-old girl. The devices were removed after 20 months of treatment, and the family was instructed about a careful control and retention program that should be followed in accordance with the patient’s growth. The final result included the correction of Class III malocclusion with adequate function and excellent facial esthetics, which restored the patient’s self-esteem and provided personal motivation. The outcomes showed good stability after 24 months of retention. The decrease in the duration of active treatment is the most important finding from the present case. Considering that facial esthetics in adolescence is a determining factor for the development of a personality and interpersonal relationships, we recommend the use of this protocol for growing patients, who will exhibit not only an improved physical appearance but also a better quality of life.

Objective: The aim of this study was to identify suitable polynomial regression for modeling the average growth trajectory and to estimate the relative development of the rib eye area, scrotal circumference, and morphometric measurements of Guzerat young bulls.Methods: A total of 45 recently weaned males, aged 325.8±28.0 days and weighing 219.9±38.05 kg, were evaluated. The animals were kept on Brachiaria brizantha pastures, received multiple supplementations, and were managed under uniform conditions for 294 days, with evaluations conducted every 56 days. The average growth trajectory was adjusted using ordinary polynomials, Legendre polynomials, and quadratic B-splines. The coefficient of determination, mean absolute deviation, mean square error, the value of the restricted likelihood function, Akaike information criteria, and consistent Akaike information criteria were applied to assess the quality of the fits. For the study of allometric growth, the power model was applied.Results: Ordinary polynomial and Legendre polynomial models of the fifth order provided the best fits. B-splines yielded the best fits in comparing models with the same number of parameters. Based on the restricted likelihood function, Akaike's information criterion, and consistent Akaike's information criterion, the B-splines model with six intervals described the growth trajectory of evaluated animals more smoothly and consistently. In the study of allometric growth, the evaluated traits exhibited negative heterogeneity (b<1) relative to the animals' weight (p<0.01), indicating the precocity of Guzerat cattle for weight gain on pasture.Conclusion: Complementary studies of growth trajectory and allometry can help identify when an animal's weight changes and thus assist in decision-making regarding management practices, nutritional requirements, and genetic selection strategies to optimize growth and animal performance.

Souza, Velci Queiroz de,Pereira, Arione da Silva,Silva, Giovani Olegario da,Carvalho, Fernando Iraja Felix de,Oliveira, Antonio Costa de The Korean Society of Crop Science 2008 Journal of crop science and biotechnology Vol.11 No.1

This work aimed to evaluate 11 potato families for insect resistance horticultural traits. The families were derived from crosses between introduced insect resistant and adapted genotypes. A randomized complete block design, with three replications was used. The plot consisted of 25 genotypes of a family, summing up to 75 genotypes tested per family. Two susceptible cultivars were included in the experiment as checks. The genotypes were evaluated for insect resistance, tuber yield traits, tuber appearance and tuber skin smoothness. The genetic value for the intensity of insect attack in the leaves and in the tubers was lower(higher resistance) in the 11 families than in the checks. For yield traits, there was no predominant effect among the families regarding the origin of the resistant donor species(Solanum berthaultii and/or S. chacoense). However, there was a large contribution of the C-1485-16-87 recurrent parent in crosses with resistant genotypes for tuber yield and tuber number. In relation to tuber appearance, only the family derived form the C-1485-16-87/ ND140(S. berthaultii) cross did not differ from the checks. had genetic value tuber skin smoothness, it was identified that families derived from S. berthaultii resistant parents showed higher genetic values than the check cultivars. For tuber skin smoothness, the genetic values of the families neither differed significantly from each other nor from the checks.

Objective: An experiment was conducted to evaluate the effects of increasing levels of spineless cactus (0%, 33%, 66%, and 100%) used as a substitute for wheat bran in buffalo diets on quantitative and qualitative traits of the meat and carcass. Methods: Twenty Murrah buffaloes at 18 months of age, with a mean initial weight of 292.9±57.3 kg, were randomly allocated to four treatments with five replicates. The animals were slaughtered after 90 days in the feedlot. The effects of spineless cactus as a replacement for wheat bran in the diet of the buffaloes on the carcass and meat traits, slaughter weight, carcass yield and carcass measurements were studied. Results: Increased spineless cactus levels led to linear reduction in average daily gain, slaughter weight, hot and cold carcass weight, compactness index and in the amount of muscle in the carcass, and there is no difference between the control treatment and the 33% replacing level for these parameters. The quality of the meat was not influenced by the treatments. Conclusion: Spineless cactus can replace wheat bran by up to 33% in sugarcane-based diets for buffaloes, without influencing quantitative and qualitative traits of the meat and carcass.

Macroscopic, Histological, and Microbiological Characterization of Contact Lesions at the Tibiotarsal Region of Broilers

Ricardo Cavani,Marcela da Silva Rubio,Khauston Augusto Pereira Alves,Lucas José Luduverio Pizauro,Marita Vedovelli Cardozo,Paulo Lourenço Silva,Iran José Oliveira Silva,Fernando Antônio Avila 한국축산식품학회 2022 한국축산식품학회지 Vol.42 No.2

Brazil is considered as a great broiler feet exporter, especially for the Chinese trade. Contact lesions at the tibiotarsal region are responsible for economic losses and there is no model for its classification, thereby this study presents a fast and practical grade system to be used in the poultry industry and proposes these lesion characterizations into three different grades. For this, correlation was made between macroscopic, histological findings and microbiological quantification (Escherichia coli, Staphylococcus spp., Streptococcus spp. and sulphite-reducing clostridia) from contact lesions in the tibiotarsal region of 112 broiler carcasses, divided in four groups (n=28), accordingly to the lesion’s intensity. There were no significant differences in microbiological quantification among the groups (p>0.05) except for the grade 3 group, as grade 1 and 2 lesions were in the early stages and histopathological changes such as ulceration were not observed. In grade 3 lesion group, it was observed bacterial cocci grume and ulceration at the articular region and significantly higher microbiological count (p<0.05) for E. coli and Staphylococcus spp. In conclusion, the visual standard proposed in this work, correlated and confirmed by the histopathologic, and microbiologic characterization, allows to precise and fast ascertainment of the contact lesion grade in the tibiotarsal regions of broiler carcasses. Moreover, it should be highlighted that grades 1 and 2 alterations are not caused by an inflammatory process caused by pathogenic agents and should not be considered a public health risk.

JPEG Pleno: Providing representation interoperability for holographic applications and devices

Peter Schelkens,Touradj Ebrahimi,Antonin Gilles,Patrick Gioia,오관정,Fernando Pereira,Cristian Perra,Antonio M. G. Pinheiro 한국전자통신연구원 2019 ETRI Journal Vol.41 No.1

Guaranteeing interoperability between devices and applications is the core role of standards organizations. Since its first JPEG standard in 1992, the Joint Photographic Experts Group (JPEG) has published several image coding standards that have been successful in a plethora of imaging markets. Recently, these markets have become subject to potentially disruptive innovations owing to the rise of new imaging modalities such as light fields, point clouds, and holography. These so‐called plenoptic modalities hold the promise of facilitating a more efficient and complete representation of 3D scenes when compared to classic 2D modalities. However, due to the heterogeneity of plenoptic products that will hit the market, serious interoperability concerns have arisen. In this paper, we particularly focus on the holographic modality and outline how the JPEG committee has addressed these tremendous challenges. We discuss the main use cases and provide a preliminary list of requirements. In addition, based on the discussion of real‐valued and complex data representations, we elaborate on potential coding technologies that range from approaches utilizing classical 2D coding technologies to holographic content‐aware coding solutions. Finally, we address the problem of visual quality assessment of holographic data covering both visual quality metrics and subjective assessment methodologies.

Carolina R. Barbosa,Gabriel H. Machado,Hugo M. Azevedo,Fernando S. Rocha,José C. Filho,Arielly A. Pereira,Otávio L. Rocha 대한금속·재료학회 2020 METALS AND MATERIALS International Vol.26 No.3

In this work, solidification and T6-heat treatment experiments were performed with the Al7Si0.3Mg alloy in order to investigatethe effect of processes parameters on the microstructure and microhardness (HV). A directional solidification devicewas used, and the solidification thermal parameters investigated were the growth and cooling rates (VL and TR). The heattreatment applied was the T6 (T6-HT), under the following conditions: solution treatment for 3 h at 520 ± 2 °C, followed byquenching in warm water (70 ± 20 °C), aging for 1, 2, 3 and 4 h at 155 ± 2 °C and air-cooling. The microstructure observedin both as-cast and T6-heat treated samples is composed of a primary phase consisting of an Al-rich dendritic network andsecondary eutectic phases, located within the interdendritic regions, formed by Si and Mg2Siparticles and Fe-intermetallicphases. The dendritic microstructure was characterized by secondary dendritic spacing (λ2) and, for both investigated samples,a single mathematical expression was proposed on the λ2 dependence with the position in the ingot. Spheroidized-likeeutectic Si particles have been found in both analyzed samples for finer microstructures. Elements quantitative and qualitativemicroanalysis by SEM/EDS as well as HV measurement at the dendritic and interdendritic regions attest to the effectivenessof the T6-heat treatment. It is highlighted in this work that mathematical expressions have been proposed to characterizethe HV dependence on aging time.
