Among the most co-occurring conditions in autism spectrum disorders (ASD), there are sleep disorders which may exacerbate associated behavioral disorders and lead to intensification of existing autistic symptoms. Several studies investigating the use of melatonin in the treatment of sleep disorders in ASD have shown comparative efficiency in sleep with little or no side effects. Here we report a case of ASD with non-24-hour rhythm and the effect of melatonin in circadian parameters by actigraphy. ...

Different parasites that commonly occur concomitantly can influence one another, sometimes with unpredictable effects. We evaluated pathological aspects of dogs naturally co-infected with Leishmania infantum and Ehrlichia canis. The health status of the dogs was investigated based on histopathological, hematological and biochemical analyses of 21 animals infected solely with L. infantum and 22 dogs co- infected with L. infantum and E. canis. The skin of both groups showed chronic, predominantly ...

We evaluated the mechanisms involved in insulin-induced vasodilatation after acute resistance exercise in healthy rats. Wistar rats were divided into 3 groups: control (CT), electrically stimulated (ES) and resistance exercise (RE). Immediately after acute RE (15 sets with 10 repetitions at 70% of maximal intensity), the animals were sacrificed and rings of mesenteric artery were mounted in an isometric system. After this, concentration–response curves to insulin were performed in control condition ...

The sacrococcygeal teratoma (SCT) is the most frequent tumor in the neonatal period. Alpha-fetoprotein (AFP) levels fall after tumoral resection, although the time required for level normalization has not been established. The authors evaluate the time required for AFP levels to reach normal levels in 6 infants with prenatal diagnosis of SCT who underwent surgery for resection. The mean time required for AFP level normalization was 9 months. All patients were alive and 1 had neurogenic bladder. AFP ...

The purpose of this study was to quantify, identify and compare the protozoa populations in the rumen of different ages of beef cattle raised in tropical pastures during the dry season. We sampled the ruminal fluid of 36 steers, 34 cows and 30 calves, all crossbred Nelore. The ruminal fluid was diluted in 10% formaldehyde solution and decimal dilutions were prepared in saline solution to quantify small, medium and large protozoa in Sedgewick Rafter chamber. A total of 135,800 protozoa were evaluated ...

Higher MIS has been associated with higher mortality and poorer health-related quality of life (HRQOL) in maintenance hemodialysis (MHD) patients. It is interesting to investigate associations of each component with mortality and patient-reported outcomes (PROs), that is, HRQOL and depression symptoms, and if MIS associations are generalizable for diverse populations.

Understanding the architecture of gene expression is fundamental to unravel the molecular mechanisms regulating complex traits in bovine, such as intramuscular fat content (IMF) and backfat thickness (BFT). These traits are economically important for the beef industry since they affect carcass and meat quality. Our main goal was to identify gene expression regulatory polymorphisms within genomic regions (QTL) associated with IMF and BFT in Nellore cattle. For that, we used RNA-Seq data from 193 Nellore ...

MicroRNAs (miRNAs) are key regulators of gene expression, potentially affecting several biological processes, whose function can be altered by sequence variation. Hence, the integration of single nucleotide polymorphisms (SNP) and miRNAs can explain individual differences in economic traits. To provide new insights into the effects of SNPs on miRNAs and their related target genes, we carried out a multi-omic analysis to identify SNPs in miRNA mature sequences (miR-SNPs) associated with fatty acid (FA) ...

Feed efficiency helps to reduce environmental impacts from livestock production, improving beef cattle profitability. We identified potential biomarkers (hub genes) for feed efficiency, by applying co-expression analysis in Longissimus thoracis RNA-Seq data from 180 Nelore steers. Six co-expression modules were associated with six feed efficiency-related traits (p-value ≤ 0.05). Within these modules, 391 hub genes were enriched for pathways as protein synthesis, muscle growth, and immune response. Trait- ...

Abstract Mineral content affects the biological processes underlying beef quality. Muscle mineral concentration depends not only on intake-outtake balance and muscle type, but also on age, environment, breed, and genetic factors. To unveil the genetic factors involved in muscle mineral concentration, we applied a pairwise differential gene expression analysis in groups of Nelore steers genetically divergent for nine different mineral concentrations. Here, based on significant expression differences ...

Background: Estrogens are involved in glycemic regulation, playing an important role in the development and/or progression of insulin resistance. For that, estrogens regulate the expression of the glucose transporter protein GLUT4 (codified by the solute carrier family 2 member 4 gene, Slc2a4), thus modulating adipose and muscle glucose disposal. This regulation is a balance between ESR1-mediated enhancer effect and ESR2-mediated repressor effect on Slc2a4 gene. However, molecular mechanisms involved ...

Em muitos debates sobre as relações entre ciência e sociedade, em particular quanto à aceitação das tecnologias ou à percepção de seus riscos, existe uma hipótese subjacente: a de que a ignorância gera medo, e o medo gera desconfiança ou hostilidade contra a ciência e a tecnologia. Neste artigo mostramos que essa hipótese é questionável. Com base numa recente enquete nacional, apontamos que atitudes otimistas sobre ciência e tecnologia não dependem do nível escolar ou da informação declarada ou ...

Oxyrhopus trigeminus from Irapé Power Plant (IPP) contained vitellogenic follicles and eggs in both rainy and dry seasons and clutch size was not correlated with female snout–vent length (SVL). Sexual dimorphism was evident. Females attain larger SVL but males have longer tails. We found three females from Santa Clara Power Plant (SPP) with vitellogenic follicles, all of them collected ...

Stafne bone defects (SBDs) are generally located in the lingual cortex, close to the mandibular angle. We report the occurrence of multiple SBDs in an asymptomatic patient, a 60-year-old man, referred to a radiology clinic to undergo examination for the purpose of implant planning. The case of multiple SBD presented here, probably the first reported in the literature, reinforces the hypothesis that some cases of SBD may be the result of a focal failure during the ossification of the mandible.
