title: Clinical and anatomopathological study of urolithiasis in feedlot lambs subjected to diets with different phosphorus concentrations

description: Abstract Obstructive urolithiasis is common in farmed sheep and has a multifactorial etiology, but inadequate nutritional management is considered the most relevant condition for its occurrence. The objectives of this study were to verify the influence of two diets with different concentrations of calcium (Ca) and phosphorus (P) on the development of obstructive urolithiasis, and to describe the clinical and anatomopathological findings of the urinary system in sheep. Thirty male crossbred Santa Inês and Ile de France lambs were randomly distributed into two groups: Group 1 (G1, n = 15) - Ca: 1.9:1 P and 0.42% P; Group 2 (G2, n = 15) - Ca: P 1.5:1 and 0.65% P. The diets consisting of Coast-cross hay, soybean meal, wheat, and corn were provided for 90 consecutive days with water ad libitum. After the diagnosis of the disease, the lambs were subjected to clinical and surgical treatment, when necessary. Urolithiasis was detected in 36.7% (11/30) of lambs, 26.7% were asymptomatic and 10% (3/30) had urethral obstruction. A lamb was unobstructed after amputation of the urethral process and urethral catheterization, one died of bladder and uroperitoneum rupture, and another was sacrificed after the failure of perineal urethrostomy and cystostomy. The most frequent renal histopathological changes were vascular congestion, dilation, and tubular degeneration. Proteins in the tubular lumen were more pronounced in G2. The diets were rich in concentrate and had adequate Ca:P ratios, but caused calculogenesis, showing that excess minerals and a small amount of roughage can cause disease in the herd.

title: Post-Hoc Comparison Tests for Odds Ratios

description: The null hypothesis of homogeneity of odds ratio across the strata is testedby several tests. When the null hypothesis is rejected, means at least one ofthe odds ratios signicantly diers from others. Post hoc tests are used afterthe null hypothesis of equality of groups is rejected. Those tests aim to revealthe true dierences between groups. In this paper, we propose post-hoc pro-cedures that control familywise type-I error. These procedures provide thehomogeneous subsets that appear in the same homogeneous subset that arenot signicantly dierent. The suggested procedures are applied to severalCOVID-19 data sets.

title: Dietary supplementation of tilapia juveniles reared in bft (bioflocs) tanks with dl-methionine

description: Abstract The present study aimed at determining the effects of dietary DL-methionine supplementation on the water quality, bioflocs composition and Nile tilapia juvenile’s (initial body weight = 2.76 ± 0.06 g) growth performance in BFT rearing tanks (18 fish/100-L tank). Fish were or not subjected to artificial feed restriction. The experimental treatments consisted of two control groups: 1 - no feed restriction, no methionine supplementation; 2 - feed restriction at 25%, no methionine supplementation. There were also four treated groups: 1 - feed restriction at 25%, dietary DL-methionine supplementation at 0.5%; 2 - feed restriction at 25%, dietary DL-methionine supplementation at 1.0%; 3 - feed restriction at 25%, dietary DL-methionine supplementation at 2.0%; 4 - feed restriction at 25%, DL-methionine supplementation of molasses at 1.0. Supplementation of the commercial diet with DL-methionine has not affected either the water quality of the BFT Nile tilapia rearing tanks or the proximate composition of the bioflocs. After 8 weeks, weight gain of fish reared in tanks with feed restriction and dietary DL-methionine supplementation at 1% or 2% has not differed (P&gt;0.05) from the tanks without feed restriction. In conclusion, it is possible to restrict the daily feed allowances of Nile tilapia juveniles reared in BFT tanks at 25%, with no growth performance impairment, if a minimal dietary DL-methionine supplementation of 1.0% is given.

title: Quality of sorghum silage in the feed-out period: evaluation of hybrids, silo layers, and mass structure

description: Abstract This study aimed to evaluate the chemical and fermentation quality of silage from two sorghum hybrids in different layers of the silo feed-out face, as well as the interference of the aerobic exposure time of structured and/or unstructured silo face (after feed-out). The AG-2005E hybrid silage presented higher crude protein content and higher pH compared to hybrid AG-60298 (6.33% and 4.0 versus 6.06% and 3.8, respectively). Silages from stratum 0 to 20cm had the lowest dry matter content and the highest crude protein content (38% and 6.35%, respectively). The pH did not differ between layers, and the NH3 content was higher in the stratum 60 to 80cm (4.5%). During 72 hours of aerobic exposure, the unstructured silage presented a higher increase in temperature than the silage from the structured face, but this period was not enough to result in differences in dry matter, mineral matter, NH3, and pH. The chemical and fermentation quality of the silage was directly influenced by hybrid and silo stratum. After aerobic exposure, silage from the structured face seems to suffer less interference compared to the silo feed-out face.

title: Forecasting the number of vehicles thefts in Campinas/Brazil using a Generalized Linear Autoregressive Moving Average model

description: By definition, thefts are considered the act of taking away other people's mobile possessions for personal use or for others, affecting crime rates, economic indicators and enabling recent studies to create risk zones in society, contributing to insurance pricing in actuarial methods. This paper analyzes the number of vehicle thefts of 38 locations near Campinas/São Paulo, Brazil, using a GLARMA(p,q) model with Poisson and Negative Binomial response. The main feature of GLARMA(p,q) is to consider the peculiarities of counting data as high dispersion. As a result, it was possible to verify the adequacy and usefulness of the model for counting data. With specific techniques for estimating time series related to the public security area, patterns can be better understood, revealing relevant information that can be added to decision-making processes to direct public policies.

title: Chemical composition, fractionation of carbohydrates and nitrogen compounds, ruminal degradation kinetics, and in vitro gas production of cactus pear genotypes

description: Abstract The aim of this study was to evaluate the chemical composition, fractionation of carbohydrates and nitrogen compounds, degradation parameters, and in vitro ruminal fermentation of cactus pear genotypes. The experiment was conducted in a completely randomized design with 4 cactus pear genotypes and 4 replicates. The evaluated cactus pear genotypes were: Miúda (Nopalea cochenillifera Salm Dyck), IPA Sertânia (Nopalea cochenillifera), Gigante (Opuntia ficus indica Mill), and Orelha de Elefante Mexicana (Opuntia stricta Haw), all in natura. Samples were randomly collected at different points in the experimental area. Whole plants were collected 24 months after field crop establishment. N. cochenillifera Salm Dyck presented the highest dry matter, acid detergent insoluble protein, non-fibrous carbohydrate, total digestible nutrients, digestible energy, total carbohydrates, and fractions A + B1 (P&lt;0.05), while presenting lower neutral detergent fiber corrected for ash and protein, acid detergent fiber, and cellulose in relation to the other genotypes studied (P&lt;0.05). The in vitro true digestibility of neutral detergent fiber was high for the genotypes N. cochenillifera Salm Dyck and N. cochenillifera Dyck, which also presented high in vitro total gas production (P&lt;0.05). The cactus pear genotypes show adequate chemical characteristics to be composed part of diets offered to ruminants. However, supplementation is necessary to increase the dry matter and fiber contents. The Nopalea cochenillifera Salm Dyck genotype presented the highest proportions of total digestible nutrients, non-fibrous carbohydrates, non-protein nitrogen, unavailable nitrogen fraction total, and high gas production in relation to the other analyzed genotypes 24 months after field crop establishment.

title: A generalized time series model based on Kumaraswamy distribution to predict double-bounded relative humidity data

description: In this study, Kumaraswamy seasonal autoregressive moving average (KSARMA) model was developed to predict double-bounded relative humidity time-series data. In the proposed model, we used the conditional maximum-likelihood method to estimate parameters of the model. For the conditional score vector and conditional Fisher information matrix, the closed type expression were derived. This paper conjointly discusses interval estimation, hypothesis testing, model selection and forecasting. We also used a Monte Carlo simulation to evaluate the finite sample performance of conditional likelihood estimators (CMLEs) and white noise test.

title: Anatomy of the basal nuclei of Alouatta belzebul

description: Abstract The basal nuclei are well-defined bodies of neurons with specific functions, located inside the white medullary center of the brain, directly involved with the motor system, participating greatly in the planning and control processes of movements. Studies on these nuclei in non-human primates are small and in the Alouatta belzebul species, nonexistent. The aim of the present study was to describe the morphology of the nuclei at the base of the brain of Alouatta belzebul. Ten male and female Alouatta belzebul brains were used, where after removal and coronal cut of the brain, the Mayland technique was performed to show the basal nuclei. There was the presence of the caudate nucleus, lentiform nucleus (this formed by the putamen, medial globus pallidus and lateral globus pallidus), claustrum and substantia nigra, which, functionally, are related to motor control. The substantia nigra is part of the midbrain and is also related to learning resulting from the effects of dopamine, responsible for activating the reward and addiction system in the telbrain and is also related to the red nucleus, which is also a midbrain nucleus. In Alouatta belzebul the red nucleus is present. It was found in the literature that degeneration of substantia nigra cells can cause Parkinson's disease in Macaca fasciculares, and because Alouatta belzebul has the same anatomical structures in the basal nuclei of the base of Macaca fasciculares, it is suggested that studies of functional evaluation of these structures should be carried out to verify whether Alouatta belzebul can be used as an experimental model for Parkinson's disease.

title: Bayesian inference for the reliability of generalized inverted exponential distribution under progressive type-I interval censoring

description: In this paper, we consider the maximum likelihood (ML) and the Bayesian estimators of the parameters, reliability and hazard functions for the generalized inverted exponential distribution under progressive type-I interval censoring. We propose EM algorithm to obtain the ML estimators. The asymptotic confidence intervals are constructed based on the ML estimators. In order to construct the asymptotic confidence intervals of the reliability and hazard functions, we compute variances of them by using delta method. It is observed that the closed-form expressions for the Bayesian estimates cannot be obtained. So we use Tierney-Kadane's approximation and Gibbs sampling method to obtain these estimates. We also derive the Bayesian credible intervals by using Gibbs sampling. Monte-Carlo simulation study is performed to compare the performances of the proposed methods concerning different sample sizes and censoring schemes. Finally, a real data set is analyzed for illustrative purposes.

title: Zebrafish (Danio rerio) meets bioethics: the 10Rs ethical principles in research

description: Abstract Zebrafish (Danio rerio) is a tropical fish species widely used in research, worldwide. The development of genetically modified animals and the increasing number of zebrafish breeding facilities due to their emerging use in several research fields, opened room for new ethical challenges for research carried out with this species. It is necessary to raise the scientific community’s awareness of the ethical standards and laws in force, on animal research. Thus, the aim of the current study is to describe 10 Rs ethical principles by using zebrafish as model system in research. The classical 3 Rs concerning animal welfare, namely replacement, reduction and refinement; and the added 7 Rs related to scientific (registration, reporting, robustness, reproducibility and relevance) and conduct principles (responsibility, and respect) in zebrafish research are herein presented and critically discussed. The use of these 10 Rs by researchers, institutions and the Animal Ethics Committee is recommended to support regulations, decision-making about and the promotion of zebrafish health and welfare in research.

title: Application of Bayesian analysis on risk factors of coronary artery disease

description: Ischemic heart disease (or Coronary Artery Disease) is the most common cause of death in various countries, characterized by reduced blood supply to the heart. Statistical models make an impact for evaluating the risk factors which are responsible for mortality and morbidity during IHD (Ischemic heart disease). In this work, due to count data, we propose Poisson, Negative Binomial and also utilize a flexible class of zero inflated models such as Zero-Inflated Poisson (ZIP) and Zero-Inflated Negative Binomial (ZINB) models estimated by the method of MLE and are compared to assess the most appropriate model for the underlying data. The forward and backward model selection procedures are also taken to permit the most significant factors associated with heart disease. The ZIP model is identified as the most appropriate one in this work. Moreover, a Bayesian estimation is chosen to account for prior on regression coefficients in a small sample size setting. This estimation also evolves as an alternative to traditionally used MLE based methods for such data. As per our simulation studies: the proposed method has better finite sample performance than the classical method with tighter interval estimates and better coverage probabilities. The simulation is based on R-software.
