Abstract Effects were assessed of the dilutants TRIS and ACP - 101c® with the addition of different guinea fowl (Numida meleagris) egg yolk concentrations. Fifteen ejaculates were collected from five goats of the Anglo Nubian breed. The ejaculates were pooled and then divided into 12 groups, two control groups (GC1 TRIS, with 2.5% Gallus gallus domesticus hen egg yolk GOGD), (GC2 Control Group ACP - 101c®, with the addition of 2.5% Gallus gallus domesticus hen egg yolk GOGD) and ten experimental groups (EG), containing TRIS and ACP added with different concentrations of egg yolk from guinea hen (Numida meleagris) (TRIS 2,5% GONM; TRIS 5% GONM; TRIS 10% GONM; TRIS 15% GONM; TRIS 20% GONM; ACP® 2,5% GONM; ACP® 5% GONM; ACP® 10% GONM; ACP® 15% GONM; ACP® 20% GONM). Then cryopreservation was carried out and the samples stored in liquid nitrogen (-196 °C). After seven days, the samples were thawed and assessed for spermatic kinetics, immunofluorescence and sperm morphology. Analysis of GOMN by the CASA system showed that the various parameters were similar to those of GOGD (P>0.05). The membrane integrity, mitochondrial potential and the acrosome were not influenced by the treatment (P>0.05) nor by the dilutant used for cryopreservation (P>0.05). The spermatic morphology was also preserved by the different GOGD and GONM concentrations in the ACP® and TRIS dilutants, with no statistically significant differences (P<0.05). It was concluded that Numida meleagris egg yolk, as external membrane cryoproctant added to the dilutants ACP-101c® and TRIS, improved goat semen quality.

RESUMO Exostoses ou hiperostoses são crescimentos ósseos benignos originados da cortical óssea e dependem de sua localização para uma denominação mais precisa. Os tipos mais comuns encontrados na cavidade oral são o Tórus Palatino e o Tórus Mandibular. Exostoses bucais e palatais acometem a face vestibular do processo alveolar na maxila e/ou na mandíbula (comumente na região de molares e pré-molares) e a superfície do processo alveolar posterior (usualmente na área da tuberosidade maxilar), respectivamente. A etiologia das exostoses ainda não foi esclarecida, mas acredita-se em uma interação entre fatores ambientais e genéticos. São usualmente assintomáticas, a não ser que a mucosa se torne ulcerada. A frequência aumenta com a idade, tendo sua maior prevalência a partir de 60 anos de idade, sendo mais comuns em homens e sofrendo influências étnicas. É importante uma avaliação minuciosa para o correto diagnóstico, visto que outras lesões, como os osteomas, possuem características clínicas semelhantes às das exostoses. A maior parte das exostoses é diagnosticada clinicamente em conjunto com interpretações radiográficas, tornando a biópsia dispensável e o tratamento é usualmente desnecessário. O objetivo deste artigo foi relatar um caso clínico de exostose maxilar bilateral, incomum, em uma paciente do sexo feminino. Se uma quantidade excessiva de osso está presente, as exostoses podem mostrar uma relativa radiopacidade nas radiografias dentárias. Inicialmente foram realizadas radiografias periapicais e radiografia panorâmica para avaliar as alterações. Devido ao tamanho das exostoses, realizou-se uma Tomografia Computadorizada de Feixe Cônico, para confirmação do diagnóstico. A paciente encontra-se em acompanhamento.

ABSTRACT Exostoses or hyperostoses are benign bony outgrowths originating from the cortical bone and depend on their location for a more precise designation. The most common types found in the oral cavity are the torus palatinus and the torus mandibularis. Buccal and palatal exostoses are located along the buccal aspect of the maxilla and/or the mandible (commonly in the premolar and molar areas) and on the palatal aspect of the maxilla (usually in the tuberosity area), respectively. The etiology of exostoses still hasn’t been enlightened but an interaction between environmental and genetic factors is accredited. They are usually asymptomatic, unless the mucosa becomes ulcerated. The frequency of exostoses increases with age, having their biggest prevalence from 60 years old, being more common in men and suffering ethnic influences. A thorough evaluation is important for the correct diagnosis since other lesions have similar clinical characteristics to the exostoses such as osteomas. The majority of exostoses are diagnosed clinically along with radiographic interpretations, making the biopsy dispensable and the treatment is usually unnecessary. The aim of this article was to describe a case report of bilateral maxillary exostosis, unusual, in a female patient. If an excessive amount of bone is present the exostoses may exhibit a relative radiopacity on dental radiographs. Initially, periapical and panoramic radiographs were performed to evaluate the alterations. Due to the size of the exostoses a concomitant Cone Beam Computed Tomography was performed to confirm the diagnosis. The patient is in follow-up.

Abstract Inflammatory external root resorption (IERR) is a pathological process defined by the progressive loss of dental hard tissue, dentin, and cementum, resulting from the combination of the loss of external root protective apparatus and root canal infection. It has been suggested that healing patterns after tooth replantation may be influenced by the genetic and immunological profiles of the patients. The purpose of the present investigation was to evaluate the DNA methylation patterns of 22 immune response-related genes in extracted human teeth presenting with IERR. Methylation assays were performed on samples of root fragments showing IERR and compared with healthy bone tissue collected during the surgical extraction of impacted teeth. The methylation patterns were quantified using EpiTect Methyl II Signature Human Cytokine Production PCR Array. The results revealed significantly higher hypermethylation of the FOXP3 gene promoter in IERR (65.95%) than in the bone group (23.43%) (p < 0.001). The ELANE gene was also highly methylated in the pooled IERR sample, although the difference was not statistically significant (p= 0.054). Our study suggests that the differential methylation patterns of immune response-related genes, such as FOXP3 and ELANE, may be involved in IERR modulation, and this could be related to the presence of root canal infection. However, further studies are needed to corroborate these findings to determine the functional relevance of these alterations and their role in the pathogenesis of IERR.

Resumo Objetivo: investigar a frequência de aleitamento materno exclusivo, a introdução precoce de outros alimentos e a associação com o baixo peso em crianças brasileiras. Métodos: analisaram-se registros de menores de 6 meses com dados inseridos no Sistema de Vigilância Alimentar e Nutricional em 2015; investigaram-se associações, por regressão de Poisson. Resultados: encontraram-se prevalências de aleitamento exclusivo, 56,1% (IC95% 55,3;56,8), baixo peso para idade, 8,1% (IC95% 7,7;8,5), e baixo índice de massa corporal (IMC) para idade, 5,7% (IC95% 5,3;6,7); agua ou chás e fórmulas infantis foram os alimentos introduzidos mais precocemente; crianças em aleitamento materno exclusivo apresentaram menor prevalência de baixo peso (RP=0,73 - IC95% 0,61;0,87) e de baixo IMC (RP=0,69 - IC95% 0,56;0,85); o consumo de fórmulas infantis se associou ao deficit de peso (RP=1,35 - IC95% 1,15;1,58). Conclusão: reforçou-se a importância do aleitamento materno exclusivo para o adequado crescimento até os 6 meses.

Abstract Objective: to investigate the frequency of exclusive breastfeeding, early introduction of other foods and association with prevalence of low weight in Brazilian children. Methods: we analyzed records of children under 6 months of age held on the Food and Nutrition Surveillance System for the year 2015; associations were investigated through Poisson Regression. Results: we found prevalence of 56.1% (95%CI 55.3;56.8) for exclusive breastfeeding, 8.1% (95%CI 7.7;8.5) for low weight for age, and 5.7% (95%CI 5.3;6.7) for low BMI for age; water or teas and infant formulas were the earliest foods introduced; underweight prevalence was lower (PR=0.73 - 95%CI 0.61;0.87) as was prevalence of low BMI (PR=0.69 - 95%CI 0.56;0.85) among exclusively breastfed infants; infant formula intake was associated with low weight (PR=1.35 - 95%CI 1.15;1.58). Conclusion: the importance of exclusive breastfeeding for adequate growth in the first 6 months of life was reinforced.
