13. Oxygen consumption remains stable while ammonia excretion is reduced upon short time exposure to high salinity in Macrobrachium acanthurus (Caridae: Palaemonidae), a recent freshwater colonizer
ABSTRACT Palaemonid shrimps occur in the tropical and temperate regions of South America and the Indo-Pacific, in brackish/freshwater habitats, and marine coastal areas. They form a clade that recently (i.e., ~30 mya) invaded freshwater, and one included genus, Macrobrachium Bate, 1868, is especially successful in limnic habitats. Adult Macrobrachium acanthu

14. Participation of the arcRACME protein in self-activation of the arc operon located in the arginine catabolism mobile element in pandemic clone USA300
ABSTRACT Staphylococcus aureus pandemic clone USA300 has, in addition to its constitutive arginine catabolism (arc) gene cluster, an arginine catabolism mobile element (ACME) carrying another such cluster, which gives this clone advantages in colonisation and infection. Gene arcR, which encodes an oxygen-sensitive transcriptional regulator, is inside ACME an

15. Chronic tophaceous gout in patients with psoriasis
Abstract: Psoriasis is a chronic inflammatory disease of multifactorial etiology influenced by genetic, immunological, and environmental factors. We report the case of a patient with psoriasis for more than 25 years who developed hyperuricemia and chronic tophaceous gout with unusual appearance. In psoriasis, hyperuricemia may occur by increased epidermal ce

16. Effects of purine nucleotide administration on purine nucleotide metabolism in brains of heroin-dependent rats
ABSTRACT Heroin is known to enhance catabolism and inhibit anabolism of purine nucleotides, leading to purine nucleotide deficiencies in rat brains. Here, we determined the effect of exogenous purine nucleotide administration on purine nucleotide metabolism in the brains of heroin-dependent rats. Heroin was administrated in increasing doses for 9 consecutive

17. Aminotransferase and glutamate dehydrogenase activities in lactobacilli and streptococci
ABSTRACT Aminotransferases and glutamate dehydrogenase are two main types of enzymes involved in the initial steps of amino acid catabolism, which plays a key role in the cheese flavor development. In the present work, glutamate dehydrogenase and aminotransferase activities were screened in twenty one strains of lactic acid bacteria of dairy interest, either

18. Nutritional assessment as predictor of complications after hematopoietic stem cell transplantation
ABSTRACT Introduction: Nutritional support is pivotal in patients submitted to hematopoietic stem cell transplantation. Nutritional status has been associated with time of engraftment and infection rates. In order to evaluate the association between nutritional parameters and clinical outcomes after transplantation a cohort of transplant patients was retros

19. Biomolecules produced in liquid-state fermentation by a marine-derived fungus, Penicillium roqueforti
Screening of biomass of a new marine-derived strain of Penicillium roqueforti, as produced by liquid-state fermentation, led to the identification of several volatile organic compounds active in the fatty acid pathway as well as fragments produced by their catabolism, terpenoids, and metabolites from the shikimic acid pathway. In addition, five non-volatile

20. Ciclooxigenase-2 modula in vivo a expressão de marcadores da osteoclastogênese e genes envolvidos no metabolismo ósseo em resposta ao lipopolissacarídeo bacteriano / Ciclooxygenase-2 modulates in vivo the expression of osteoclastiogenesis makers and genes involved in bone metabolism in response to bacterial lipopolysaccharide
During an inflammatory response, several mediators are locally released in order to stimulate cellular and humoral immune response. Through the action of cyclooxygenase and lipoxygenase enzymes structural changes occur in the arachidonic acid chain leading to synthesis of prostaglandins or leukotrienes and lipoxins, respectively. Such mediators are responsib

21. 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

22. 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

23. Investigação de parâmetros de estresse oxidativo e inflamação em pacientes com doença de Fabry submetidos à terapia de reposição enzimática : correlações com globotriaosilceramida
Fabry disease (FD) is an X-linked inborn error of glycosphingolipid catabolism due to deficient activity of C-galactosidase A. Patients present as main findings angiokeratomas in skin and acroparesthesias and usually die in adult age of renal failure and stroke. As a consequence of the enzyme deficiency, the substrates (mainly globotriaosylceramide - Gb3) ac

24. Crescimento, hematologia e metabolismo de pacu (Piaractus mesopotamicus) submetido ao exercício aeróbico e alimentado com níveis crescentes de proteínas
The composition of the diet, the metabolic adaptations and variations in the activity of the fish are the main factors responsible for seasonal changes in physiological variables. It is known that aerobic exercise can improve the fish growth due to: the enhancement of feed conversion, reduced dominance, increased protein synthesis and lipid and glucose catab
