Length-weight relationships of fish from sandy beaches / Relação peso-comprimento de 16 espécies de peixes que ocorrem perto de praias arenosas ao longo da bacia do baixo rio Negro na Amazônia brasileira

This study estimated the length–weight relationships of 16 fish species occurring close to the shores of sandy beaches along the lower Negro River basin, Brazilian Amazon. The specimens were captured for one day each month, in October to November 2016, early in the morning and early evening, using trawl net (20 m length and 3.5 m height, 5 mm mesh between opposite knots). Measurements were taken for standard length (SL 0.1 cm precision) and total weight (TW 0.01 g precision). The parameters a and b of the equation WT = a.LTb were estimated. The a values ranged from 0.0018 to 0.0226 and b values ranged from 2.5271 to 3.3244. This study also provides new data on of maximum lengths for six species, Amazonsprattus scintilla, Brycon pesu, Moenkhausia megalops, Pachyurus paucirastrus, Reganella depressa and Trachydoras microstomus, and new reports of the LWRs parameters of 15 fish species.(AU)

Medial malleolus malunion with secondary tibiotalar and syndesmotic incongruence - two case reports and ''box resection'' for its treatment.

INTRODUCTION: Ankle fractures are among the most common injuries treated by orthopaedic surgeons. Malunion is one of the possible complications, and corrective surgery is often used to avoid long-term disability. However, few studies address medial malleolus malunion and the best revision surgery technique is controversial. We describe a new surgical technique, the "box resection". MATERIAL AND METHODS: We present two cases of medial malleolus malunion with secondary talus lateral translation and syndesmotic incongruence. In order to restore a congruent tibiotalar joint, we performed the described technique. RESULTS: We record significant improvement of AOFAS Score and range of motion in both cases, with resolution of pain symptoms. Postoperative radiographs show a congruent mortise with syndesmosis reduction. CONCLUSION: The box resection allowed immediate talus medial translation to its original position. It is a simple and effective solution, with a good functional outcome.

INTRODUCCIÓN: La consolidación viciosa del maléolo interno es una posible complicación en las fracturas maleolares. Su tratamiento es difícil y controvertido, por el momento no hay una solución estándar. Proponemos una nueva técnica quirúrgica para el tratamiento de estos casos que denominamos "resección en caja". MATERIAL Y MÉTODOS: Presentamos dos casos de consolidación viciosa del maléolo interno, asociados con traslación lateral del astrágalo y incongruencia de la sindesmosis, donde aplicamos la técnica quirúrgica descrita. RESULTADOS: En ambos casos, obtuvimos una mejora significativa en el puntaje AOFAS y en el rango de movilidad, así como en la resolución de las molestias por dolor. Las radiografías muestran mortajas congruentes y anatómicas, con una reducción satisfactoria de la sindesmosis. CONCLUSIÓN: La técnica de "resección en caja" es simple y eficaz produciendo un buen resultado clínico y funcional.

Valor nutritivo do capim-xaraés em três intensidades luminosas / Nutritive value of xaraés palisade grass in three light intensities

Este trabalho teve como objetivo avaliar o valor nutritivo e a força de cisalhamento da cultivar de Urochloa brizantha (syn Brachiaria brizantha) cv Xaraés submetida a três intensidades luminosas e quatro cortes. O experimento foi conduzido na FMVZ - Unesp de Botucatu, com delineamento experimental em blocos ao acaso, sendo os tratamentos: luminosidade natural, redução de 30% e 60% de luz, com quatro cortes e três repetições. As análises realizadas foram: composição bromatológica, digestibilidade e a força de cisalhamento. Não houve diferença na digestibilidade entre os tratamentos em nenhum dos cortes, mas a qualidade forrageira foi influenciada pelos níveis de intensidade de luz, tendo o tratamento com 60% de redução de luminosidade apresentado maiores concentrações de proteína bruta e cinzas, menores teores de fibra em detergente neutro, hemicelulose, celulose e força de cisalhamento. Em relação aos cortes estudados, o primeiro teve o menor intervalo de corte e produziu forragem com qualidade superior em comparação ao último, pois obteve menor teor de fibra em detergente ácido, lignina, hemicelulose, celulose e consequente menor força de cisalhamento. Portanto, a redução de 60% de luminosidade é benéfica à qualidade e à força de cisalhamento da cultivar Xaraés.(AU)

This study aimed to evaluate the nutritive value and shear strength of the Xaraés grass (Urochloa brizantha) under the three intensities of light and four cuts. The experiment was conducted at FMVZ - UNESP, Botucatu, with a randomized block design, with the following treatments: natural luminosity, 30% and 60% light reduction, with four cuts and three replications. The analyzes were bromatological composition, digestibility, and shearing strength. There was no difference in digestibility between the treatments in any of the cuts, forage quality was influenced by the light intensity levels, and the treatment with 60% of light reduction produced higher concentrations of crude protein and ash, lower levels of neutral detergent fiber, hemicellulose, cellulose and shear strength. According to the studied cuts, the first one had the lowest cut interval and produced superior forage compared with the last one, as it obtained lower fiber content in acid detergent, lignin, hemicellulose, cellulose and consequent lower shear force. Therefore, the reduction of 60% of luminosity is beneficial to the quality and shear force of the Xaraés palisade grass.(AU)

Modeling children's development in gross motor coordination reveals key modifiable determinants. An allometric approach.

Children change their body size, shape, and gross motor coordination (GMC) as they grow. Further, GMC is expected to link to changes in children's body size, physical activity (PA), and physical fitness (PF). The objective was to model GMC changes in children followed longitudinally and to investigate associations between these changes and PA and PF levels. A total of 245 children (122 girls) were observed at 6 years of age and followed annually until 9 years. A sequence of allometric models was fitted, that is, 1. body mass, stature, and PA; 2. addition of four PF tests; 3. addition of four more PF tests. In Model 1, changes in GMC are nonlinear, and body mass (-0.60 ± 0.07, P < .001) and stature (2.91 ± 0.35, P < .001) parameter estimates were significant suggesting children with a more linear body size/shape showed higher GMC performances. Girls tend to outperform boys across time, and PA was not associated with GMC changes. Model 2 fitted the data better, and the PF tests (handgrip, standing long jump, 50-yard dash, and shuttle run) were significantly linked to GMC change. In Model 3, adding the remaining PF tests did not change the order of any factors importance. The greatest GMC changes were achieved by children whose body size/shape has an ectomorphic dominance across the years. Considering that leaner and physically fitter children tended to be more coordinated, physical education should also focus on PF development in components related to muscular strength, speed, agility, and aerobic capacity, along with nutritional education to reduce fat mass.

Clinical and Nutritional Factors Associated With Early Mortality After Heart Transplantation.

OBJECTIVE: The aim of this work was to verify the association between clinical and nutritional factors and mortality in the 1st 30 days after heart transplantation. METHODS: This was a retrospective study of patients who underwent heart transplantation in a public hospital in Brazil from January 2013 to August 2015. The clinical and nutritional factors analyzed were: body mass index, body surface area, cachexia, infection, duration of orotracheal intubation, ejection fraction, mean pulmonary pressure, Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) score, hemoglobin, and diabetes mellitus. The primary outcome was mortality in the 1st 30 days after heart transplantation, and secondary outcomes were infection, acute kidney insufficiency, and duration of orotracheal intubation. We performed chi-square test, unpaired t test, and logistic regression in the analyses. A P value of < .05 was considered to be significant. RESULTS: The sample had 103 patients, of which 16 patients (15.53%) died within 30 days after heart transplantation. We observed a relationship between death and orotracheal intubation duration (P < .01), postoperative creatinine (P < .01), acute kidney injury (P < .01), and INTERMACS score (P = .01) in the bivariate analysis but not in the multivariate model. CONCLUSIONS: Clinical and nutritional factors had no impact on mortality up to 30 days after heart transplantation in this study, although orotracheal intubation duration, postoperative creatinine, acute kidney injury, and INTERMACS score were individually associated with early death.

Body mass index, cardiorespiratory fitness and cardiometabolic risk factors in youth from Portugal and Mozambique.

OBJECTIVES: The objectives of this study are to examine differences in cardiometabolic risk indicators, as well as their prevalences, in Portuguese and Mozambican youth, and to investigate the associations between weight status and cardiorespiratory fitness levels with cardiometabolic risk. METHODS: The sample comprises 721 adolescents (323 Mozambican and 398 Portuguese), aged 10-15 years. Anthropometry (height, sitting height, weight and waist circumference), blood pressure, serum-fasting triglycerides, high-density lipoprotein cholesterol and glucose, and cardiorespiratory fitness were measured. Maturity offset was estimated and a cardiometabolic risk score adjusted for sex, age and biological maturity was computed. Adolescents were classified as normal weight and overweight/obese as well as fit or unfit (cardiorespiratory fitness). RESULTS: Portuguese youth have better cardiometabolic and cardiorespiratory fitness profiles. About 32% and 30% of Portuguese boys and girls, respectively, are overweight/obese; in Mozambicans, these prevalences are 7.5% for boys and 21% for girls; in addition, 81.6% of Portuguese boys and 77.7% of Portuguese girls were classified as cardiorespiratory fit, against 54% and 44.4% of Mozambican boys and girls, respectively. No statistically significant differences (P>0.05) were found between Mozambicans and Portuguese for the cluster of three or more cardiometabolic risk indicators. A positive relationship (P<0.001) was found between weight status and cardiometabolic risk in adolescents from both countries; however, a negative association (P<0.001) between cardiorespiratory fitness and cardiometabolic risk was only found among Portuguese youth. CONCLUSIONS: Portuguese and Mozambican youth differ in their cardiometabolic risk profiles, body weight and cardiorespiratory fitness, favoring Portuguese. Overweight/obesity and low cardiorespiratory fitness levels are related to a worse cardiometabolic risk profile, being relevant to design public health intervention strategies to reduce excess weight and increase cardiorespiratory fitness.

Effect of exercise training on Ca2+ release units of left ventricular myocytes of spontaneously hypertensive rats

In cardiomyocytes, calcium (Ca2+) release units comprise clusters of intracellular Ca2+ release channels located on the sarcoplasmic reticulum, and hypertension is well established as a cause of defects in calcium release unit function. Our objective was to determine whether endurance exercise training could attenuate the deleterious effects of hypertension on calcium release unit components and Ca2+ sparks in left ventricular myocytes of spontaneously hypertensive rats. Male Wistar and spontaneously hypertensive rats (4 months of age) were divided into 4 groups: normotensive (NC) and hypertensive control (HC), and normotensive (NT) and hypertensive trained (HT) animals (7 rats per group). NC and HC rats were submitted to a low-intensity treadmill running protocol (5 days/week, 1 h/day, 0% grade, and 50-60% of maximal running speed) for 8 weeks. Gene expression of the ryanodine receptor type 2 (RyR2) and FK506 binding protein (FKBP12.6) increased (270%) and decreased (88%), respectively, in HC compared to NC rats. Endurance exercise training reversed these changes by reducing RyR2 (230%) and normalizing FKBP12.6 gene expression (112%). Hypertension also increased the frequency of Ca2+ sparks (HC=7.61±0.26 vs NC=4.79±0.19 per 100 µm/s) and decreased its amplitude (HC=0.260±0.08 vs NC=0.324±0.10 ΔF/F0), full width at half-maximum amplitude (HC=1.05±0.08 vs NC=1.26±0.01 µm), total duration (HC=11.51±0.12 vs NC=14.97±0.24 ms), time to peak (HC=4.84±0.06 vs NC=6.31±0.14 ms), and time constant of decay (HC=8.68±0.12 vs NC=10.21±0.22 ms). These changes were partially reversed in HT rats (frequency of Ca2+ sparks=6.26±0.19 µm/s, amplitude=0.282±0.10 ΔF/F0, full width at half-maximum amplitude=1.14±0.01 µm, total duration=13.34±0.17 ms, time to peak=5.43±0.08 ms, and time constant of decay=9.43±0.15 ms). Endurance exercise training attenuated the deleterious effects of hypertension on calcium release units of left ventricular myocytes.

Endurance exercise training attenuated the deleterious effects of hypertension on calcium release units of left ventricular myocytes.

Níveis de inclusão do farelo de arroz parboilizado em rações para leitões na fase de creche / Inclusion levels of parboiled rice bran in piglet diets in the nursery phase

Foram conduzidos dois ensaios para avaliar a utilização do farelo do farelo integral de arroz parboilizado (FIAP) em rações para leitões na fase de creche. No primeiro, foram utilizados 14 suínos machos castrados para a avaliação nutricional do ingrediente em ensaio de digestibilidade. O delineamento experimental foi o inteiramente ao acaso, com dois tratamentos e sete repetições por tratamento. O FIAP apresenta 17,15% de PB, elevado teor em fibras (33,75% de FDN e 15,91% de FDA) e teor reduzido de energia metabolizável, próximo a 2320kcal/kg. No segundo experimento, foram utilizados 60 leitões machos castrados, com o objetivo de avaliar o desempenho zootécnico, a ocorrência de diarreia e a viabilidade econômica do farelo de arroz parboilizado. O delineamento experimental foi em blocos ao acaso, com cinco tratamentos (0, 4, 8, 12 e 16% de inclusão) e seis repetições. Não houve diferença significativa entre o tratamento controle e os tratamentos teste (P>0,05), assim como para a análise de regressão, em que os crescentes níveis de inclusão do ingrediente não resultaram em piora no desempenho (P>0,05). O FIAP pode ser incluído até o nível de 16% em rações para leitões na fase de creche.(AU)

Two assays were conducted to evaluate the parboiled rice bran in piglet's diets in the nursery phase. In the first, 14 male castrated piglets were allotted to determine the nutritional value of parboiled rice bran in a digestibility assay. A completely randomized design, with 2 treatments and 7 replicates per treatment were used. The parboiled rice bran presents 17.15% of CP and high fiber content (33.75% of NDF and 15.91% of ADF) and low metabolizable energy (2320kcal/kg). In the second assay, 60 male castrated piglets were used to evaluate the effect of inclusion on productive performance, diarrhea incidence and economic viability of parboiled rice bran. A randomized block design was used, with 5 treatments (0, 4, 8, 12 and 16%) and 6 replicates. There was no difference between treatments and control treatment as well as in regression analysis, and the increasing levels of parboiled rice bran did not reduce the performance of animals. In conclusion, parboiled rice bran can be included up to 16% in diets for piglets in the nursery phase.(AU)

No segundo experimento, foram utilizados 60 leitões machos castrados, com o objetivo de avaliar o desempenho zootécnico, a ocorrência de diarreia e a viabilidade econômica do farelo de arroz parboilizado. O delineamento experimental foi em blocos ao acaso, com cinco tratamentos (0, 4, 8, 12 e 16% de inclusão) e seis repetições. Não houve diferença significativa entre o tratamento controle e os tratamentos teste (P>0,05), assim como para a análise de regressão, em que os crescentes níveis de inclusão do ingrediente não resultaram em piora no desempenho (P>0,05). O FIAP pode ser incluído até o nível de 16% em rações para leitões na fase de creche...

Two assays were conducted to evaluate the parboiled rice bran in piglet's diets in the nursery phase. In the first, 14 male castrated piglets were allotted to determine the nutritional value of parboiled rice bran in a digestibility assay. A completely randomized design, with 2 treatments and 7 replicates per treatment were used. The parboiled rice bran presents 17.15% of CP and high fiber content (33.75% of NDF and 15.91% of ADF) and low metabolizable energy (2320kcal/kg). In the second assay, 60 male castrated piglets were used to evaluate the effect of inclusion on productive performance, diarrhea incidence and economic viability of parboiled rice bran. A randomized block design was used, with 5 treatments (0, 4, 8, 12 and 16%) and 6 replicates. There was no difference between treatments and control treatment as well as in regression analysis, and the increasing levels of parboiled rice bran did not reduce the performance of animals. In conclusion, parboiled rice bran can be included up to 16% in diets for piglets in the nursery phase...

Abordagem sobre os diferentes processos de secagem empregados na obtenção de extratos secos de plantas medicinais / Approach on different drying processes employed for obtaining dry extracts from medicinal plants

Na indústria farmacêutica de fitoterápicos, o extrato seco é considerado tecnologicamente viável para fins de produção em larga escala, devido à estabilidade física, química e microbiológica, além da facilidade de padronização dos princípios ativos. Entre as técnicas de secagem empregadas na preparação de extratos secos, encontra-se a nebulização ou spray-dryer, o leito de jorro, a liofilização e a evaporação rotativa. A escolha do processo de secagem é motivada pela potencialidade dos diferentes equipamentos secadores, na secagem de materiais presentes na forma líquida, no caso, soluções extrativas de plantas medicinais, fornecendo um produto de alta qualidade e com investimento relativamente baixo.

In the pharmaceutical industry of herbal medicines, the dried extract is considered technologically feasible for large-scale production, due to its physical stability, possibility of chemical and microbiological analyses and the ease of standardization of the active ingredients. Among the drying techniques used in the preparation of dry extracts are a mist or spray-dryer, the spouted bed, freeze-drying and rotary evaporation. The choice of the drying process is motivated by the potential of different drying equipments and materials present in liquid form, in this case, solutions of herbal extracts provide a high quality product and a relatively modest investment.

Teor de flavonóides totais em produtos contendo pata-de-vaca (Bauhinia L. ) comercializados em farmácias de Recife/PE / Total flavonoid content in products containing "pata-de-vaca" (Bauhinia L. ) sold in pharmacies in Recife/PE

O objetivo deste estudo foi avaliar, através de metodologia espetrofotométrica, o teor de flavonóides totais em produtos contendo pata-de-vaca (Bauhinia L.) comercializados em farmácias de Recife, estado de Pernambuco, Brasil. Foi utilizada metodologia de complexação com cloreto de alumínio. Os resultados foram expressos em µg equivalentes de rutina por mililitro (µg ER mL-1). Foram adquiridos e avaliados nove produtos (drogas rasuradas, extratos e cápsulas). As concentrações de flavonóides totais das amostras variaram de 1,663 ± 0,144 a 28,698 ± 0,187 µg ER mL-1. Os resultados não apresentaram uniformidade quanto à concentração de flavonóides totais, indicando falta de padronização nas preparações fitoterápicas e possível ineficácia dos produtos comercializados.

The aim of this study was to evaluate, through spectrophotometric methodology, the total flavonoid content in products containing "pata-de-vaca" (Bauhinia L.) sold in pharmacies in Recife, state of Pernambuco, Brazil. The methodology of complexation with aluminum chloride was used. The results were expressed as µg of rutin equivalents per milliliter (µg RE mL-1). Nine products (drug erasures, extracts and capsules) were purchased and evaluated. The concentrations of total flavonoids in the samples ranged from 1.663 ± 0.144 to 28.698 ± 0.187 µg RE mL-1. The results showed no uniformity as to the total flavonoid content, indicating a lack of standardization in herbal preparations and a possible inefficiency of the marketed products.

Immunohistochemical expression of types I and III collagen antibodies in the temporomandibular joint disc of human foetuses.

The objective was to study the morphology of the articular disc and analyse the immunohistochemical expression of types I and III collagen markers in the temporomandibular joint (TMJ) disc of human foetuses of different gestational ages. Twenty TMJ from human foetuses supplied by Universidade Federal de Uberaba with gestational ages from 17 to 24 weeks were studied. The gestational age of the foetuses was determined by measuring the crown-rump (CR) length. Macroscopically, the foetuses were fixed in 10% formalin solution and dissected by removing the skin and subcutaneous tissue and exposing the deep structures. Immunohistochemical markers of type I and III were used to characterize the existence of collagen fibres. Analysis of the immunohistochemical markers of types I and III collagen revealed the presence of heterotypical fibril networks.
