1. Increasing feed allowance in low-fish meal diets allows for a reduction in dietary methionine for juvenile Litopenaeus vannamei raised in green-water tanks
ABSTRACT A 10-week study was conducted to evaluate the effect of feed allowance and graded levels of dietary methionine (Met) on growth performance of Litopenaeus vannamei. Juvenile shrimp of 1.83±0.14 g were stocked in 42 outdoor green-water tanks of 1 m3 under 120 shrimp m−2. Animals were fed under two feed allowances, regular and 30% in excess. Five di

2. Uso de fármacos e consumo de nutrientes por idosos
Background : Physiological changes related to aging leads to nutritional deficiencies that may be aggravated by inadequate intake of nutrients in the diet and polypharmacy. Objectives : The paper 1 had the objective of analyzing the potential pharmacological interactions among drugs taken by elderly patients. The paper 2 aimed to determine the profile of nut

3. Desempenho,composição e utilização de nutrientes no híbrido (cachara x jandiá) alimentados com variações de carboidratos e lipídio na dieta / Performance, carcass composition, and use of nutrients of the hybrid of carnivorous Pseudoplastitoma reticulatum X omnivorous Leiarius marmoratus fed a varied carbohydrate and lipid diet
Avaliou-se a influência de diferentes níveis de carboidratos / lipídios na dieta de peixes (CHO/ L) sobre o desempenho , composição corporal e utilização de nutrientes de híbrido, carnívoros (Pseudoplastistoma reticulatum ) x onívoros (Leiarius marmoratus) . Quatro dietas isoproteicas foram formuladas contendo proteína bruta a 43%, com aumento dos

4. The inhibitory role of sympathetic nervous system in the Ca2+-dependent proteolysis of skeletal muscle
Mammalian cells contain several proteolytic systems to carry out the degradative processes and complex regulatory mechanisms to prevent excessive protein breakdown. Among these systems, the Ca2+-activated proteolytic system involves the cysteine proteases denoted calpains, and their inhibitor, calpastatin. Despite the rapid progress in molecular research on

5. Protein-sparing therapy after major abdominal surgery: lack of clinical effects. Protein-Sparing Therapy Study Group.
OBJECTIVE: A prospective multicenter randomized trial was designed to evaluate the clinical efficacy of postoperative protein-sparing therapy. SUMMARY BACKGROUND DATA: The metabolic effect of postoperative protein-sparing therapy has been shown by several studies, but the clinical utility of this treatment has not been investigated by large prospective trial

6. The Metabolic Response to Hypocaloric Protein Diets in Obese Man
Exogenous protein in the absence of other calories can cause protein-sparing, but the mechanisms involved are controversial. It has been postulated that low insulin and high fat-derived substrate levels are necessary and sufficient conditions for such protein-sparing. We therefore established such conditions with differing protocols of protein input to defin

7. Lack of Cocaine Self-Administration in Mice Expressing a Cocaine-Insensitive Dopamine Transporter
Cocaine addiction is a worldwide public health problem for which there are no established treatments. The dopamine transporter (DAT) is suspected as the primary target mediating cocaine's abuse-related effects based on numerous pharmacological studies. However, in a previous study, DAT knockout mice were reported to self-administer cocaine, generating much d

8. Two distinct mechanisms alter p53 in breast cancer: mutation and nuclear exclusion.
Twenty-seven cases of inflammatory breast cancer were screened for the presence of the p53 protein by immunocytochemical methods using a monoclonal antibody directed against the p53 protein. Three groups were detected: 8 cases (30%) had high levels of p53 in the nucleus of the cancer cells; 9 cases (33%) had a complete lack of detectable staining; 10 cases (

9. Can methotrexate be used as a steroid sparing agent in the treatment of polymyalgia rheumatica and giant cell arteritis?
OBJECTIVE: To investigate whether methotrexate (MTX) has a steroid sparing effect in the treatment of polymyalgia rheumatica (PMR) and giant cell arteritis (GCA). METHODS: We carried out a randomised double blind, placebo controlled study in 40 patients with PMR, six of whom also had clinical symptoms of GCA. A temporal artery biopsy specimen was available f

10. Immunological tolerance to allergenic protein determinants: a therapeutic approach for selective inhibition of IgE antibody production.
Administration of stable conjugates prepared by coupling protein antigens such as ovalbumin or antigen E of ragweed extract to the synthetic random copolymer of D-glutamic acid and D-lysine (D-GL) is effective in inducing a state of long-lasting, antigen-specific immunological tolerance in experimental animals. A striking aspect of the tolerance induced by p

11. Long-term memory for instrumental responses does not undergo protein synthesis-dependent reconsolidation upon retrieval
Recent evidence indicates that certain forms of memory, upon recall, may return to a labile state requiring the synthesis of new proteins in order to preserve or reconsolidate the original memory trace. While the initial consolidation of “instrumental memories” has been shown to require de novo protein synthesis in the nucleus accumbens, it is not known

12. Castration differentially alters basal and leucine-stimulated tissue protein synthesis in skeletal muscle and adipose tissue
Reduced testosterone as a result of catabolic illness or aging is associated with loss of muscle and increased adiposity. We hypothesized that these changes in body composition occur because of altered rates of protein synthesis under basal and nutrient-stimulated conditions that are tissue specific. The present study investigated such mechanisms in castrate
