1. 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

2. Avaliação da associação entre o tratamento com metformina e suplementação nutricional com leucina no metabolismo protéico de ratos portadores do tumor de Walker 256 / Effects of metformin treatment associated to leucine rich-diet on protein metabolism in Walker 256 tumour-bearing rats
O crescimento do câncer promove o desenvolvimento de caquexia em função de intensa espoliação de nutrientes, principalmente, de gordura e proteína corpórea total. A via de sinalização da mTOR controla o crescimento celular e alguns estudos apontam que a inibição dessa via por metformina (M) pode diminuir a taxa de desenvolvimento tumoral. Desse mo

3. Avaliação dos efeitos da hipertermoterapia por ultrasom associada a agentes antiangiogênicos no tratamento do tumor experimental de walker / EVALUATION OF THE HIPERTHERMOTHERAPY EFFECTS BY ULTRASOUND ASSOCIATED TO ANTIAGIOGENIC AGENTS IN THE TREATMENT OF WALKER EXPERIMENTAL TUMOR
The traditional methods of cancer treatment, like the chemotherapy and radiotherapy, even though they are effective in many types of tumours, they find frequently resistant neoplasic cells population, beyond presenting a low security margin to the patients. The hyperthermia use associated to the chemotherapy and radiotherapy are plenty mentioned as profitabl

4. Cancer-caquexia e suplementação nutricional : impacto da dieta rica em leucina no controle do metabolismo proteico muscular
Caquexia, presente na maioria dos hospedeiros com câncer, é um estado caracterizado pela perda involuntária de peso. Pacientes com caquexia apresentam expectativa de vida muito reduzida e menor qualidade de vida. Nos pacientes com câncer-caquexia há intensa mobilização de substratos dos tecidos da carcaça do organismo hospedeiro ocorrendo, preferenci

5. Physical training associated to tumor growth and nutritional suplementation in Walker 256 tumor-bearing rats / Atividade fisica associada ao crescimento tumoral e suplementação nutricional : estudo experimental em ratos jovens portadores do carcinossarcoma de Walker 256
The intense nutrients mobilisation of the host carcass tissue, in function of the neoplastic growth, leads to the host cachexia. Present in most of the patients with cancer, the cachexia is the state characterized by the involuntary weight loss that overtakes the protein muscle depletion increasing the degradation and/or decreasing the protein synthesis proc

6. Comparison of rat liver and Walker 256 carcinosarcoma tRNAs.
The complete nucleotide sequences of both rat liver and Walker 256 mammary carcinosarcoma tRNAAsn reveal that they are identical except for the nucleotide present in the wobble position of the anticodon loop. The rat liver tRNAAsn contains the Q nucleoside, whereas the tumour tRNAAsn contains an unmodified guanosine. The tRNAs from both tissues also show sig

7. Experimental hypercalcaemia and whole blood clotting
Experimental hypercalcaemia was induced in rats by (1) transplantation of the solid Walker 256 tumour, and (2) intraperitoneal injections of calcium gluconate. Whole blood clotting was studied by means of thromboelastography and whole blood clotting times in polystyrene and glass test tubes. At serum calcium levels between 10·3 and 11·5 m-equiv/l a slight
