1. Expression profile of endothelin receptors (ETA and ETB) and microRNAs-155 and -199 in the corpus cavernosum of rats submitted to chronic alcoholism and diabetes mellitus
Recent evidence shows that chronic ethanol consumption increases endothelin (ET)-1 induced sustained contraction of trabecular smooth muscle cells of the corpora cavernosa in corpus cavernosum of rats by a mechanism that involves increased expression of ETA and ETB receptors. Our goal was to evaluate the effects of alcohol and diabetes and their relationship

2. Myostatin promotes distinct responses on protein metabolism of skeletal and cardiac muscle fibers of rodents
Myostatin is a novel negative regulator of skeletal muscle mass. Myostatin expression is also found in heart in a much less extent, but it can be upregulated in pathological conditions, such as heart failure. Myostatin may be involved in inhibiting protein synthesis and/or increasing protein degradation in skeletal and cardiac muscles. Herein, we used cell c

3. Bone turnover after bariatric surgery
ABSTRACT Objective The aim of the present study was to evaluate parameters of bone and mineral metabolism after bariatric surgery. Subjects and methods This sectional study included data from medical records from 61 bariatric surgery (BS) patients (minimum period of 6 months after the procedure) and from 30 class II and III obese patients as a control gr

4. Alanyl-glutamine attenuates 5-fluorouracil-induced intestinal mucositis in apolipoprotein E-deficient mice
Apolipoprotein E (APOE=gene, apoE=protein) is a known factor regulating the inflammatory response that may have regenerative effects during tissue recovery from injury. We investigated whether apoE deficiency reduces the healing effect of alanyl-glutamine (Ala-Gln) treatment, a recognized gut-trophic nutrient, during tissue recovery after 5-FU-induced int

5. The shift from low to high non-structural protein 1 expression in rotavirus-infected MA-104 cells
A hallmark of group/species A rotavirus (RVA) replication in MA-104 cells is the logarithmic increase in viral mRNAs that occurs four-12 h post-infection. Viral protein synthesis typically lags closely behind mRNA synthesis but continues after mRNA levels plateau. However, RVA non-structural protein 1 (NSP1) is present at very low levels throughout viral rep

6. Protein metabolism, feed energy partitioning, behavior patterns and plasma cortisol in Nellore steers with high and low residual feed intake
The objective was to evaluate protein turnover, nitrogen balance, feed energy partitioning, behavior patterns and plasma cortisol in Nellore (B. indicus) cattle with high and low residual feed intake (RFI = actual minus expected dry matter intake). Seventy-two Nellore steers (16 to 21 months-old, 334±19 kg initial body weight) were fed a feedlot diet for 70

7. Atividade física e suplementação nutricional de leucina associadas ao crescimento tumoral : estudo do perfil hormonal de ratos implantados com carcinossarcomia de Walker 256 / Physical activity and nutritional supplementation with leucine associated with tumor growth : study of hormonal profile in Walker 256
The cancer-cachexia is characterized by the development of anorexia, asthenia, weight loss, early satiety, anaemia and especially changes in the metabolism of carbohydrate, fat and protein in these cancer patients. The amino acid leucine acts promoting cell signalling by inhibiting the protein catabolism and stimulating the protein synthesis in skeletal musc

8. Protein turnover, amino acid requirements and recommendations for athletes and active populations
Skeletal muscle is the major deposit of protein molecules. As for any cell or tissue, total muscle protein reflects a dynamic turnover between net protein synthesis and degradation. Noninvasive and invasive techniques have been applied to determine amino acid catabolism and muscle protein building at rest, during exercise and during the recovery period after

9. Use of conditioners in the production of Tifton 85 grass hay
The objectives of this study were to estimate the curve of dehydration, bromatological composition and occurrence of fungi in Tifton 85 grass, submitted to four methods of dehydration. The curves of dehydration were studied in a completely randomized design with a 4 × 11 factorial scheme with four drying systems (1 conditioning + 1 turn-over; 2 conditioning

10. Haptoglobin gene subtypes in three Brazilian population groups of different ethnicities
Haptoglobin is a plasma hemoglobin-binding protein that limits iron loss during normal erythrocyte turnover and hemolysis, thereby preventing oxidative damage mediated by iron excess in the circulation. Haptoglobin polymorphism in humans, characterized by the Hp*1 and Hp*2 alleles, results in distinct phenotypes known as Hp1-1, Hp2-1 and Hp2-2, whose frequen

11. Protein metabolism, body chemical composition, carcass traits and meat quality of Nellore steers (Bos indicus) as a function of their residual feed intake / Metabolismo protéico, composição corporal, características de carcaça e qualidade de carne de novilhos Nelore (Bos indicus) em função de seu consumo alimentar residual
Residual feed intake (RFI) is a feed efficiency trait that is independent of growth rate and mature weight. Genetic improvement in RFI may reduce the costs of feeding cattle, however a better understanding of biological processes underlying variation in RFI is necessary. Moreover, associations between RFI and carcass quality have been poorly investigated in

12. O papel do sistema dopaminérgico nigroestriatal na neurobiologia do sono / The role of the dopaminergic nigrostriatal system in the sleep neurobiology.
Dopamine (DA) is critically involved in regulating neural processes responsible for complex movements and emotions. Alterations in central dopaminergic neurotransmission have been implicated in important neurological and psychiatric disorders such as Parkinsons disease (PD) and schizophrenia. In addition, DA has recently been recognized as instrumental in th
