RESUMO

(1) Background and objectives: Maturity-onset diabetes of the young (MODY) is a group of diabetes caused by gene defects related to insulin secretion. MODY1, MODY2, and MODY3 are the most common and account for approximately 80% of all cases. Other types are relatively rare. This study describes the clinical, analytical, and genetic characteristics of a patient with MODY10, and diabetic nephropathy, retinopathy, and functional hypogonadism diagnosis. (2) Materials and methods: A clinical case was analyzed and whole exome generation sequencing (WES) was used to detect mutations related to a monogenic variant. (3) Results: A seventeen-year-old male patient, who was diagnosed with apparent type 1 diabetes at the age of eight was started with insulin therapy. He came to the emergency room with glycemic decompensation, facial, and lower limb edema. During his evaluation, he had near-nephrotic range proteinuria of 2902 mg/24 h, a kidney ultrasound showing mild pyelocalyceal dilation, proliferative diabetic retinopathy, and was also diagnosed with functional hypogonadotropic hypogonadism. These comorbidities improved with adequate glycemic control. WES showed missense variant c.94G>A (p.Gly32Ser) in the INS gene, according to Clinvar corresponding to MODY10. It was a "de novo" variant not reported in his parents. (4) Conclusions: Monogenic diabetes (MD) is rare and MODY10 is among the less frequent types. MODY should be suspected in patients with type 1 phenotype with negative autoimmunity even in the absence of a family history of diabetes. To the best of our knowledge, we present here the first patient with these phenotypic traits of MODY10 reported in Latin America.

RESUMO

SUMMARY: The aim was to analyze the relationship between somatic maturation and physical performance in male youth soccer players belonging to a professional Mexican academy. In 121 male soccer aged 11 to 16 years from a professional academy the peak height velocity (PHV), percentage of adult height (PAS), jump capacity, sprint, intermittent speed and muscle mass were estimated. ANOVA was conducted to compare performance variables among maturity somatic categories and percentiles were calculated based on maturity offset using LMS method. Furthermore, a general linear model was employed to determine the explanatory variables for performance. Post-PHV soccer players demonstrated superior physical performance across several tests compared to Pre-PHV (p<0.001) and Circa-PHV (p<0.001) players. The smoothed percentile values of performance tests, based on somatic maturation, indicated progressive performance enhancement as individuals approached PHV (-2 to 2 years from PHV) (p<0.005). PHV was associated with jump capacity (p<0.001) and intermittent speed (p=0.007) while PAS was associated with time in sprint (p=.0004). In conclusion PHV and PAS explained better performance than chronological age, body composition characteristics, injuries, or training factors.


El objetivo fue analizar la relación entre la maduración somática y el rendimiento físico en futbolistas juveniles masculinos pertenecientes a una academia profesional mexicana. Métodos. En 121 futbolistas masculinos de 11 a 16 años de una academia profesional se estimó la velocidad máxima en altura (VPH), porcentaje de altura adulta (PAS), capacidad de salto, sprint, velocidad intermitente y masa muscular. Se realizó ANOVA para comparar variables de desempeño entre categorías somáticas de madurez y se calcularon percentiles en función de la compensación de madurez utilizando el método LMS. Además, se empleó un modelo lineal general para determinar las variables explicativas del desempeño. Los jugadores de fútbol post-PHV demostraron un rendimiento físico superior en varias pruebas en comparación con los jugadores Pre-PHV (p<0,001) y Circa-PHV (p<0,001). Los valores percentiles suavizados de las pruebas de rendimiento, basados en la maduración somática, indicaron una mejora progresiva del rendimiento a medida que los individuos se acercaban al PHV (-2 a 2 años desde el PHV) (p<0,005). PHV se asoció con la capacidad de salto (p<0,001) y velocidad intermitente (p=0,007) mientras que PAS se asoció con el tiempo en sprint (p=0,0004). En conclusión PHV y PEA explicaron un mejor rendimiento que la edad cronológica, las características de composición corporal, las lesiones o los factores de entrenamiento.

RESUMO

SUMMARY: Frailty affects the functional autonomy (FA) of older adults and could manifest itself in muscle imbalances in the limbs, resulting in a disparity in size and strength between them. In Chile, information on the relationship between muscle strength (MS) levels and FA asymmetries in older women is limited. This study related the levels of MS, anthropometric parameters, and asymmetries of the lower and upper limbs, with the FA of a group of older Chilean women. The study included 39 women who participated, and their FA was evaluated using the GDLAM index (IG). Based on the score obtained in the IG, they were classified by percentiles as Group 1 with favorable FA (P ≤ 50) and Group 2 with low FA (P > 50). Anthropometric parameters were BMI, fat percentage, bone mass, circumferences (arm, thigh, calf), diameters (humerus, femur) and upper/lower limb strength was evaluated to determine asymmetries. The differences between the covariates of both groups were evaluated using the student's t test and the Mann-Whitney test for independent samples. G1 presented less asymmetry (p > 0.05) in the lower limbs and greater calf circumference than G2 (p < 0.05). G1 presented greater bilateral strength (dominant and non-dominant limb) compared to G2 (p < 0.05). The covariates of age, anthropometry, MS, and lower/upper limb asymmetries influence FA in older women.


La fragilidad afecta la autonomía funcional (AF) de las personas mayores y podría manifestarse en desequilibrios musculares en los miembros, dando lugar a una disparidad de tamaño y fuerza entre ellos. En Chile, la información que relaciona los niveles de fuerza muscular (FM) y las asimetrías con la AF en mujeres mayores es limitada. Este estudio relacionó los niveles de FM, parámetros antropométricos y asimetrías de los miembros inferiores y superiores, con la AF de un grupo de mujeres mayores chilenas. Participaron 39 mujeres, cuya AF se evaluó mediante el índice GDLAM (IG). En función de la puntuación obtenida en el IG, se clasificaron por percentiles en Grupo 1 con AF favorable (P ≤ 50) y Grupo 2 con AF baja (P > 50). Los parámetros antropométricos fueron IMC, porcentaje de grasa, masa ósea, circunferencias (brazo, muslo, pantorrilla), diámetros (húmero, fémur) y se evaluó la fuerza de los miembros superiores/ inferiores para determinar asimetrías. Las diferencias entre las covariables de ambos grupos se evaluaron mediante la prueba t de student y la prueba de Mann-Whitney para muestras independientes. G1 presentó menor asimetría (p > 0,05) en los miembros inferiores y mayor perímetro de pantorrilla que G2 (p < 0,05). G1 presentó mayor fuerza bilateral (miembro dominante y no dominante) en comparación con G2 (p < 0,05). Las covariables de antropometría, FM y asimetrías de extremidades inferiores/superiores influyen en la AF en mujeres mayores.

RESUMO

The present study aimed to estimate the height growth curve for Mexican boys and girls based on their body mass index (BMI) status (normal and overweight/obese) and to develop a height Lambda, Mu, and Sigma (LMS) growth reference for Mexican children aged 2 to 18 years. Methods: Chronological age and height records (7,097 boys and 6,167 girls) were obtained from the Mexican National Survey of Health and Nutrition database. Height growth curves were fitted using the Preece-Baines 1 (PB1) model and the LMS method. Results: Age at peak height velocity (APHV) was 12.4 and 12.7 years for overweight-obese and normal-weight boys, respectively, and was 9.6 and 10.4 years for overweight-obese and normal-weight girls, respectively. Growth velocity was higher at the age of take-off (TO) in overweight-obese children than in normal-weight children (5.2 cm/year vs. 5 cm/year in boys and 6.1 cm/year vs. 5.6 cm/year in girls); nevertheless, the growth velocity at APHV was higher for normal-weight children than for overweight-obese children (7.4 cm/year vs. 6.6 cm/year in boys and 6.8 cm/year vs. 6.6 cm/year in girls, respectively). Distance curves developed in the present study and by the World Health Organization (WHO) using LMS showed similar values for L and S parameters and a higher M value compared with the WHO reference values. Conclusion: This study concluded that overweight-obese children had earlier APHV and lower PHV than normal-weight children. Furthermore, Mexican children and adolescents were shorter than the WHO growth reference by age and sex.

RESUMO

The aim of the present study was to analyze the effects of visual morphological classification based on body structure, maturity, and musculosity on the morphometry of the reproduction system and productive parameters of beef heifers. The study was conducted for 84 days, during winter season in Brazil. Thirty non-pregnant Nellore heifers, with an average body weight 338 kg and average age 18 months, were used for the study. The heifers were housed in collective pens and fed corn silage (70%) and concentrate (30%) twice a day. All heifers were weighed weekly without prior fasting. Morphological evaluation of body structure, maturity, and musculosity was conducted in the third-middle of the experimental period by a trained evaluator, adopting a comparative methodology of visual evaluation on a scale from 1 to 6, and the heifers were classified according to the visual assessment. The effects of visual classification, time, and interactions were analyzed, considering significant effects was detected (p < 0.05). The significant (p < 0.05) results obtained were compared using Tukey test. Morphological classification did not influence the morphometry of the reproductive system or implied on time interactions. Body structure, maturity, and musculosity had no effect on dry matter intake, body weight gain, feed efficiency, and carcass dressing. However, body weight and feed efficiency were influenced by the experimental time. For both variables, significant variations were detected after 63 days of finishing in the feedlot (p < 0.001), indicating that maximum productive efficiency of feedlot-finished Nellore beef heifers was achieved at a mean body weight of 424 kg.

RESUMO

Objetivo: Evaluar la utilidad de la estimación de la presión de la arteria pulmonar fetal obtenida por ecografía doppler como indicador de madurez fetal y su correlación con los resultados neonatales en un grupo de pacientes que asistan al área de sala de parto del Hospital Central de San Cristóbal, entre marzo y julio de 2023. Métodos: Se trata de un estudio observacional, descriptivo, correlacional. La muestra fue de 90 mujeres (90 fetos) con embarazo simple entre 34 y 40 semanas de gestación. Resultados: De las variables doppler analizadas, se evidenció que la presión de la arteria pulmonar fetal disminuyó significativamente (p < 0,001) con el avance de la edad gestacional. Se determinó que existe una asociación significativa inversa entre la presión de la arteria pulmonar fetal y la madurez fetal (p < 0,001), de manera que a menor valor de la presión de la arteria pulmonar fetal se tiene un mayor porcentaje de madurez fetal. Un punto de corte de la presión de la arteria pulmonar fetal ubicado en 55,9 mm Hg determinó la sensibilidad y especificidad más alta conjuntamente para el diagnóstico de madurez pulmonar fetal, siendo su sensibilidad de 93,75 % y especificidad de 80,77 %. Con un valor predictivo positivo de 92,31 % y un valor predictivo negativo de 84 %. Conclusión: La estimación de la presión de la arteria pulmonar fetal obtenida mediante ecografía doppler es útil como indicador de madurez fetal(AU)


Objective: To evaluate the usefulness of the estimation of fetal pulmonary artery pressure obtained by doppler ultrasound as an indicator of fetal maturity and its correlation with neonatal outcomes in a group of patients attending the delivery room area of the Hospital Central de San Cristobal, between March and July 2023. Methods: This is an observational, descriptive, correlational study. The sample consisted of 90 women (90 fetuses) with a single pregnancy between 34 and 40 weeks of gestation. Results: From the doppler variables analyzed, it was evidenced that the fetal pulmonary artery pressure decreased significantly (p < 0.001) with advancing gestational age. It was determined that there is a significant inverse association between fetal pulmonary artery pressure and fetal maturity (p < 0.001), such that the lower the fetal pulmonary artery pressure value, the higher the percentage of fetal maturity. A fetal pulmonary artery pressure cut-off point located at 55.9 mm Hg jointly determined the highest sensitivity and specificity for the diagnosis of fetal lung maturity, its sensitivity being 93.75% and specificity being 80.77%. With a positive predictive value of 92.31% and a negative predictive value of 84%. Conclusion: The estimation of fetal pulmonary artery pressure obtained by doppler ultrasound is useful as an indicator of fetal maturity(AU)

RESUMO

Recent estimates of the size at first maturity (L50) of Sardinella brasiliensis showed contradictory results with a decreasing in the fish stock biomass encompassed by increasing values of L50. The methodological approach used hereby allowed to separate sardines classified in the virginal maturity stage from those categorized in the recovery stage, and ready for one next spawning event. This study evaluated the hypothesis of the existence of separated stocks experiencing distinct environmental conditions and fishing pressures which may have altered L50 estimates using a robust dataset based on biological samples collected along the entire species distribution area in the southeast-south Brazilian coast [Rio de Janeiro (RJ), São Paulo (SP), Paraná (PR), Santa Catarina (SC) and Rio Grande do Sul (RS)] between 2000 and 2018. A reclassification of the gonadal maturity stages provided a more realistic estimate of L50. Combining biological, reproductive, fishing data and the mean temperature of the catch (MTC), the leave-one-out classification correctly re-assigned individuals with an overall accuracy of 85% [100% (RJ), 45% (SP), 99% (PR), 99% (SC) and 82% (RS)]. The connectivity between the local populations of S. brasiliensis off RJ (23°S) and the southern populations is limited, contrasting to spatial structured semi-discrete population-units found between SP and RS (24°S-30°S). The northern extreme population-unit (RJ, 22°S-23°S) showed an expressive reduction of L50, and a negative correlation was detected between the increasing MTC values and the abundance of early maturing individuals and recruits of the species. Stock specific L50 estimates seemed to act as indicators of long term environmental fluctuations.

RESUMO

The short-tail yellownose skate, Zearaja brevicaudata, occurs off southern Brazil and along the Argentine continental shelf, including waters surrounding the Islas Malvinas and the upper slope, and is very frequently caught by trawl fisheries throughout its range. The age, growth, and maturity of Z. brevicaudata were investigated using 204 individuals collected by commercial fishing vessels from northern Argentina, between March 2016 and September 2019. Age was determined on a sample comprising vertebrae from 151 individuals, 60 males, ranging in size from 391 to 956 mm total length (TL), and 91 females, ranging in size from 324 to 1060 mm TL. Maximum ages determined for males and females were 22 and 29 years, respectively. A Bayesian framework was employed with a set of three candidate models to estimate growth parameters (von Bertalanffy, Gompertz, and Logistic). The von Bertalanffy model had the best fit, and the sexes showed undistinguishable growth parameters. For sexes combined, derived growth mean parameters (± S.D.) were L∞ = 1081 mm ± 64.34 mm, k = 0.09 ± 0.01 years-1, and L0 = 248 mm ± 23.52 mm. The age at maturity was estimated at 13.15 and 14.66 years for males and females, respectively.

RESUMO

SUMMARY: The handgrip strength is used as a means of individual's health prediction during life. It is used as an indicator of the nutrition status, bone fragility, presence of sarcopenia and it correlates with certain diseases and clinical complications. The research goal was to analyze the results of the hand dynamometry test, based on the chronological and biological age, and to offer normative and referent standards about children and adolescents from the Republic of North Macedonia. The study was conducted on a sample of 4031 respondents of both sexes at the age 6-14 years. In order to achieve the research goals, the measured characteristics were of the weight, height, sitting height and handgrip strength. The body mass index and biological maturity values (APHV) were obtained by using formulas. On the basis of the obtained results, it can be concluded that statistically significant differences in handgrip strength are established between the boys and girls of all age categories. Also, statistically significant differences between boys and girls are established in the hand dynamometry test of all APHV levels. In general, the use of the APHV allows a better categorization of the performance of the studied children and adolescents. With boys, the correlation between the chronological age and test was 68 %, and with girls - 77 %. The normative referent standards of the hand dynamometry test are presented in percentiles for both sexes. Thye hand dynamometry test's results during childhood and adolescence should be analyzed and interpret on the basis of biological age, and not on the chronological age. These tools can help specialists who work with children and adolescents in ethnic and epidemiological context.


La fuerza de prensión se utiliza como medio para predecir la salud del individuo durante la vida. Se utiliza como indicador del estado nutricional, fragilidad ósea, presencia de sarcopenia y se correlaciona con determinadas enfermedades y complicaciones clínicas. El objetivo de la investigación fue analizar los resultados de la prueba de dinamometría manual, con base en la edad cronológica y biológica, y ofrecer estándares normativos y referentes sobre niños y adolescentes de la República de Macedonia del Norte. El estudio se realizó en una muestra de 4031 encuestados de ambos sexos con edades comprendidas entre 6 y 14 años. Para lograr los objetivos de la investigación, las características medidas fueron el peso, la altura, la altura al sentarse y la fuerza de prensión. El índice de masa corporal y los valores de madurez biológica (APHV) se obtuvieron mediante fórmulas. Sobre la base de los resultados obtenidos, se puede concluir que se establecen diferencias estadísticamente significativas en la fuerza de prensión manual entre niños y niñas de todas las categorías de edad. Asimismo, se establecen diferencias estadísticamente significativas entre niños y niñas en la prueba de dinamometría manual de todos los niveles APHV. En general, el uso del APHV permite una mejor categorización del desempeño de los niños y adolescentes estudiados. En los niños, la correlación entre la edad cronológica y la prueba fue del 68 %, y en las niñas, del 77 %. Los estándares normativos referentes de la prueba de dinamometría manual se presentan en percentiles para ambos sexos. Los resultados de la prueba de dinamometría manual durante la infancia y la adolescencia deben analizarse e interpretarse en función de la edad biológica y no de la edad cronológica. Estas herramientas pueden ayudar a los especialistas que trabajan con niños y adolescentes en un contexto étnico y epidemiológico.

RESUMO

This study determines the reproductive patterns of puye (Galaxias maculatus) under culture conditions. A population of 567 wild fish was caught in the Cautín River, Chile, and held in captivity for four years. Mortality, sex ratio, gonadosomatic index (GSI), sexual maturity stages, spawning period, type and frequency of spawning, and fecundity were measured. The fish grew throughout the experimental period, with the fastest rate during the first half of the first year of life. The highest mortality occurred during the first three months of the experiment and during the spawning season. The sex ratio was almost 1:1 (female:male). First sexual maturity was reached at one year of age, with an average weight of 0.85 ± 0.01 g, total length of 4.85 ± 0.16 cm, and condition factor 0.0074. The highest GSI in both females (12.14 ± 0.74) and males (17.7 ± 2.70) was recorded in August. Nevertheless, the females spawned 3 to 10 times between September and February, with the highest reproductive peak between September and October. The number of embryos per female per day varied from 1 to 429, while the total number of embryos per female during the entire season evaluated varied from 163 to 1044. There was a high correlation (r = 0.82) between absolute fecundity and body weight. Although further studies are needed in this field, these results are basic for establishing future reproductive programs in captivity as a strategy for sustainable fisheries and aquaculture management.

RESUMO

Approaches to safety culture assessment may have many limits if supported exclusively by quantitative methods. Based on this, a research team developed a quantitative-qualitative approach to assess the maturity of the safety culture on an oil platform. To that end, the team sought to develop and test a method consisting of an initial ethnographic phase followed by four other distinct phases: definition of homogeneous groups; production of customized questionnaires; quantitative evaluation; and qualitative assessment. The results show the emergence of trends, from pre-defined themes in safety culture to specific levels of maturity for each of the homogeneous groups. At the same time, it was perceived that the maturity level of the groups is defined from the daily work practices developed by each one of them. This experience allowed us to propose a framework for assessing the maturity levels of safety culture for the oil and gas industry.

RESUMO

INTRODUCTION: Maturity-onset diabetes of the young (MODY) is a rare disease due to a single gene mutation that affects several family members in most cases. The Krüppel-like factor 11 (KLF11) gene mutation is associated with decreased insulin sensitivity to high glucose levels. KLF 11 has been implicated in the pathogenesis of MODY type 7 but given its low prevalence, prolonged subclinical period, and the emergence of new information, doubts are raised about its association. METHODS: A literature search of the PubMed, Scopus, and EBSCO databases was performed. The terms "Diabetes Mellitus, Type 2/genetics", "Mason-Type Diabetes" , "Maturity-Onset diabetes of the young", "KLF11 protein, human", and "Maturity-Onset Diabetes of the Young, Type 7" were used"., "Diagnosis" The search selection was not standardized. RESULTS: The KLF1 mutation is rare and represents <1% of the mutations associated with monogenic diabetes. Its isolation in European family lines in the first studies and the emergence of new variants pose new diagnostic challenges. This article reviews the definition, epidemiology, pathophysiology, diagnosis, and treatment of MODY type 7. CONCLUSION: MODY type 7 diabetes represents a rare form of monogenic diabetes with incomplete penetrance. Given its rarity, its association with impaired glucose metabolism has been questioned. Strict evaluation of glycemic control and the appearance of microvascular complications are key areas in the follow-up of patients diagnosed with MODY 7. More studies will be required to characterize the population with KLF11 mutation and clarify its correlation with MODY.

RESUMO

Purpose: This study aimed to compare the degree of maturation and development of fetal pig segmental intestinal tissue with that of spheroids created by in-vitro reaggregation of dissociated fetal intestinal cells after transplantation into immunodeficient mice. Methods: Fetal pig small intestines were transplanted as segmental grafts into the omentum and subrenal capsules of immunodeficient mice or enzymatically treated to generate single cells. Spheroids made by in-vitro reaggregation of these cells were transplanted into the subrenal capsules of immunodeficient mice. The segmental grafts and spheroids were harvested four and eight weeks after transplantation, and the structural maturity and in-vivo development of these specimens were histologically evaluated. Results: The spheroids were engrafted and supplied blood vessels from the host mice, but an intestinal layered structure was not clearly observed, and there was almost no change in size. On the other hand, the segmental grafts formed deep crypts in the mucus membrane, the inner circular layer, and outer longitudinal muscles. The crypts of the transplanted grafts harvested at eight weeks were much deeper, and the smooth muscle layer and the enteric nervous system were more mature than those of grafts harvested at the fourth week, although the intestinal peristaltic wave was not observed. Conclusions: Spheroids created from fetal small intestinal cells could not form layered structures or mature sufficiently. Conversely, segmental tissues structurally matured and developed after in-vivo transplantation and are therefore potential grafts for transplantation.

RESUMO

The aim of this study was to estimate the size at first sexual maturity (Lm) for 36 species belonging to 24 families from the marine habitat of Balochistan and Sindh in Arabian Sea, Pakistan through maximum length based an empirical and logistic model using commercial catch during June 2020 to May 2021. Individual total length (TL) was noted up to 0.1 cm using measuring broad. The Lm was calculated using two formulae; (i) log (Lm) = - 0.1246 + 0.9924 * log (Lmax) for Elasmobranchs and (ii) log (Lm) = -0.1189 + 0.9157* log (Lmax) for ray-finned fishes. The minimum Lm was recorded as 10.27 cm TL for Caranx malabaricus and 108.38 cm TL for Isurus oxyrinchus, respectively. Around Lm with 58.33% species were ranges from 19.00 cm to 25.00 cm TL. This study was estimated 16 newly Lm which is globally absent and rest 20 Lm are absent in the Arabian Sea (Pakistan coastal habitats). Therefore, the results will be helpful for the sustainable management and conservation of these marine fishes through the establishment of mesh size of trawl nets based on the size at sexual maturity (Lm).


O objetivo deste estudo foi estimar o tamanho na primeira maturidade sexual (Lm) para 36 espécies pertencentes a 24 famílias do hábitat marinho do Baluchistão e Sindh, no Mar Arábico, Paquistão, por meio de modelo empírico e logístico com base no comprimento máximo usando captura comercial, durante junho de 2020 e maio de 2021. O comprimento total individual (TL) foi anotado até 0,1 cm usando medição ampla. O Lm foi calculado por duas fórmulas; (i) log (Lm) = - 0,1246 + 0,9924 * log (Lmax) para elasmobrânquios; e (ii) log (Lm) = - 0,1189 + 0,9157* log (Lmax) para peixes com nadadeiras raiadas. O Lm mínimo foi de 10,27 cm de TL para Caranx malabaricus, e o máximo, de 108,38 cm de TL para Isurus oxyrinchus. Em 58,33% das espécies com Lm foram encontradas faixas de 19,00 cm a 25,00 cm de TL. Este estudo estimou que 16 espécies com Lm estão globalmente ausentes e as 20 espécies restantes com Lm estão ausentes no Mar Arábico (hábitats costeiros do Paquistão). Portanto, os resultados serão úteis para o manejo sustentável e a conservação desses peixes marinhos por meio do estabelecimento da malhagem das redes de arrasto com base no tamanho na primeira maturidade sexual (Lm).

RESUMO

When applied at growing phase, lighting program aims to obtain quails with body weight and physiological maturity suitable for the beginning of laying. This study evaluated lighting programs at growing phase on performance, sexual maturity and egg quality of meat quail breeders (Coturnixcoturnix) at laying phase. From 7 to 49 days of age, 300 female meat quails were subjected to three lighting programs (natural, intermittent and continuous), with 5 replicates of 20 birds each. At 49 days of age, 240 quails were transferred to a shed, maintaining the same experimental conditions. Meat quails submitted to continuous and intermittent lighting programs had higher weight of reproductive system and lower ages for first egg production and to reach 50% of egg production (P < 0.05). Quails submitted to natural lighting had lower feed intake from 49 to 70 and 71 to 92 days of age and worse feed conversion up to 114 days of age. Continuous and intermittent lighting programs resulted in more precocious quails compared to natural lighting program. Quails submitted to natural lighting at growing phase presented lower egg production during all periods, not differing for birds submitted to continuous and intermittent programs from the second period (71 to 92 days of age). Intermittent and continuous lighting result in better feed conversion of breeding quails up to 114 days and a higher percentage of laying (49 to 136 days), reducing the number of days to produce the first egg and to reach 50% of laying, in relation to natural lighting.


Quando aplicado na fase de crescimento, o programa de luz visa obter codornas com peso corporal e maturidade fisiológica adequados para o início da postura. Este estudo avaliou programas de iluminação na fase de crescimento sobre o desempenho, maturidade sexual e qualidade dos ovos de codornas de corte reprodutoras (Coturnix coturnix) na fase de postura. Durante o período de sete a 49 dias de idade, 300 codornas de corte fêmeas foram submetidas a três programas de iluminação (natural, intermitente e contínuo), com cinco repetições de 20 aves cada. Aos 49 dias de idade, 240 codornas foram transferidas para um galpão, mantendo a mesma distribuição experimental e submetidas às mesmas condições. As aves submetidas aos programas de iluminação contínuo e intermitente na fase de crescimento apresentaram maiores peso relativo do sistema reprodutivo e consequentemente menores idades para produção do primeiro ovo e para atingir 50% da produção de ovos (P < 0.05). As aves que receberam apenas iluminação natural apresentaram menor consumo de ração nos períodos de 49 a 70 e 71 a 92 dias de idade e pior conversão alimentar até 114 dias de idade. Os programas de iluminação contínua e intermitente na fase de crescimento resultaram em codornas mais precoces quando comparados as aves submetidas ao programa de iluminação natural. Codornas submetidas a programa de luz natural na fase de crescimento apresentaram menor produção de ovos durante todos os períodos, não diferindo das aves submetidas a programas contínuos e intermitentes a partir do segundo período (71 a 92 dias de idade). A iluminação intermitente e contínua na fase de crescimento resulta em melhor conversão alimentar de codornas reprodutoras até 114 dias e maior percentual de postura (49 a 136 dias), reduzindo o número de dias para produzir o primeiro ovo e atingir 50% de postura, em relação a iluminação natural.

RESUMO

The totoaba (Totoaba macdonaldi) is an emblematic species endemic to the Gulf of California, which has been protected since the mid-70 s by Mexican and international laws. For the present study, 153 totoaba individuals were collected from 2011 to 2014, on which gonad histology analyses were carried out. We identified six ovarian phases and eleven oocyte subphases in the gonad development of females; in males, four development phases were identified. The totoaba is an iteroparous species based on the number of breeding opportunities. According to the organization of the ovary and the presence of oocyte subphases, ovarian dynamics can be considered asynchronous, as demonstrated by the multimodal distribution of oocyte diameter. The totoaba is a batch spawner that releases oocytes over several months. The reproductive period spans from February to May, with a reproductive peak in March. Likewise, the gonadosomatic index showed that the reproductive activity of totoaba peaked in March and April. The female:male sex ratio, although variable throughout the sampling period, yielded an overall value of 0.89:1, with non-significant differences between the number of females and males (P > 0.05). The length at first sexual maturity (L50%) was 1 354 mm TL for females and 1 299 mm TL for males. The average fecundity was 2 662 626 (standard error, s.e., 1 021 124) oocytes, and the average relative fecundity was 99 (s.e. 22) oocytes g-1 (ovary-free). The mean and maximum oocyte diameter showed a positive and non-significant (P > 0.05) relationship with the mean sea surface temperature.

RESUMO

The use of mixed nonlinear models reduces the residual variance by including random effects, thereby improving the estimates in growth curves. Therefore, we tested distinct mixed nonlinear models (Richards, Brody, Gompertz, Logistic, and Von Bertalanffy) to model the growth curves of Zebu cattle herds raised on pasture in Brazil. In addition, we evaluated the diversity among breeds using hierarchical cluster multivariate analysis (full linkage) based on asymptotic weight (A), maturity rate (K), absolute growth rate (AGR), and absolute maturity rate (AMR) adjusted to 205, 365, 550, and 730 days of age. Body weight data from 311,834 males and females of Guzerat, Nellore, Tabapuã, and Polled Nellore breeds provided by the Brazilian Association of Zebu Breeders were used. The Brody model considering breed-sex fixed and animal random effects was the most suitable to describe the growth in the four breeds. The Guzerat and Tabapuã males showed increased precocity (higher K values) when compared to polled Nellore and Nellore males, which were characterized by higher A and AMR values. Females were more precocious than males (high K and low A values), particularly within Tabapuã and Guzerat breeds, respectively. Regardless of sex, the highest AGR values were observed from weaning up to 2 years of age in Tabapuã and Guzerat breeds. The cluster analyses revealed two groups: (1) Polled Nellore and Nellore males with high A, AGR_205, AGR_365, AGR_550, and AGR_730 values, represented by large adult animals, and (2) males and females of Guzerat and Tabapuã, characterized as animals of increased precocity. A subgroup encompassing males of Guzerat and Tabapuã was also observed, with intermediate values ​​for all parameters. This information is useful to help breeders and producers in strategies for feeding management and defining the most precocious beef cattle breed to increase the economic gains in pasture-based raising systems.

RESUMO

Plantain is a basic component in the Puerto Ricans' diet and one of the most economically important crops on the Island. Maricongo crops, the predominant cultivar, do not satisfy the demand for fresh and processed products. The objective of this study was to evaluate the nutritional composition and in vitro digestibility of Maiden and FHIA 20 plantains in stages 1 and 5 and compare these data to Maricongo. Estimated glycemic indexes (eGI) of cultivars under conventional cooking processes (i.e., boiling, fried, baked, and steamed) were performed as well. Baked Maricongo stood out because of its lowest rapidly available glucose value (22.06%), constituting a healthier and the first cooking alternative. eGI values were classified as medium and high, where frying and baking processes presented medium values, and boiling displayed the greatest eGI for both stages. In terms of nutritional profile, this research concludes that Maiden could constitute an option to substitute or supplement Maricongo.
