Revista Brasileira de Zootecnia , 2006,
Abstract: RESUMO Avaliaram-se o pH e a concentra o de am nia ruminal (N-amoniacal), a taxa de passagem, o balan o de compostos nitrogenados e a produ o de proteína microbiana em novilhos Holandês x Zebu alimentados com dietas contendo quatro níveis de proteína bruta (10,5; 12; 13,5 e 15%), com base na matéria seca. As dietas foram constituídas de 65% de feno de capim-tifton 85 e 35% de concentrado. Foram utilizados quatro bovinos castrados fistulados no rúmen e abomaso, com peso vivo médio inicial de 487,3 kg, distribuídos em um quadrado latino 4 x 4. Cada período experimental teve dura o de 20 dias: dez para adapta o às dietas e dez para coletas. O pH e N-amoniacal foram mensurados no fluido ruminal imediatamente antes e 2, 4, 6 e 8 horas, após o fornecimento da dieta. A taxa de passagem foi determinada pelo modelo unicompartimental, utilizando-se óxido de cromo como indicador. Para determina o da produ o de proteína microbiana, utilizaram-se as bases purinas (RNA) no abomaso como indicador microbiano. A concentra o de am nia e o pH ruminal foram influenciados pelos tempos de coleta, estimando-se valores máximos de 17,43 e 6,54 mg/dL, às 3,62 e 4,17 horas após a alimenta o, respectivamente. A taxa de passagem da digesta n o foi afetada pelas dietas, registrando-se valor médio de 3,69%/h. Os fluxos de compostos nitrogenados no abomaso e a eficiência de síntese microbiana também n o foram afetados pelos níveis de proteína bruta das dietas, ao passo que o balan o de nitrogênio, expresso em g/dia, aumentou linearmente com o incremento de proteína bruta.

Abstract: the objective of this trial was to study the effects of different dietary levels of crude protein (cp) on intake and apparent total tract, intestinal, and ruminal digestibilities of nutrients in holstein x zebu steers. the diets contained [dry matter (dm) basis]: 10.5, 12, 13.5, or 15% of cp and a forage (tifton 85):concentrate ratio of 65:35. four castrated animals averaging 487.3 kg of body weight at the beginning of the trial and fitted with both abomasum and rumen cannulas were randomly assigned to a 4 x 4 latin square. each experimental period lasted 20 days with 10 days for diet adaptation and 10 days for sample collection (feces, abomasum digesta, ruminal content, and urine). chromium oxide was used as the external marker for determination of fecal excretion. increasing dietary levels of cp did not change significantly the intakes of dry matter (dm), organic matter (om), neutral detergent fiber (ndf), and total digestible nutrients (tdn). however, intake of cp increased while that of ether extract (ee) and non-fiber carbohydrate (nfc) decreased with the increment of dietary cp. apparent total tract digestibilities of dm, om, and cp all increased linearly by increasing the dietary cp from 10.5 to 15%. except for intestinal digestibility of cp that increased 2.77 percentage units for each 1% increment in the diet cp, the different dietary cp levels did not affect intestinal and ruminal digestibilities of all remaining nutrients in the current trial.

Civitas , 2002,
Abstract: O conhecimento, a informa o e a comunica o foram o paradigma da estrutura e do funcionamento das sociedades atuais. Tomando por base a pressuposto de que o conhecimento é sempre contextualiza o pelas condi es que o tornam possível, e que ele só progride na medida em que transforma essas mesmas condi es, estudam-se os movimentos sociais e as entidades representativas da sociedade, como as organiza es n o-governamentais, enquanto espa os de produ o, organiza o e inova o de conhecimentos. Cenários de disputas simbólicas onde se confrontam matrizes cognitivas e políticas diferenciadas, nesses espa os formam-se a cada vez, múltiplas configura es de comunica o e informa o, que apontam para novas formas de organizar os conhecimentos na sociedade, com sentido emancipatório. A idéia de terceiro conhecimento é construída para estudar as redes de produ o de sentidos assim constituídas.

Abstract: the objective was to undertake a careful review of a consecutive series of 120 patients with colorectal cancer approached by laparoscopic surgery (video-group, 60 patients) and by laparotomy (lap-group, 60 patients), during 12 months (may 2009 to may 2010). the average age was 58 years and 58.8 years in group-lap and 57.3 years in video-group, the majority being females in both groups (lap-group - 55.0% and video-group - 61.7%, general mean 58.3 years). all patients in both groups underwent colonoscopy and biopsy with histopathologic diagnosis of adenocarcinoma. as far as distribution of tumors in the large intestine in lap-group, 43 tumors were located in the rectum, rectosigmoid and sigmoid colon (71.7%) versus 45 in video-group (75.0%), but with differences between low rectum (lap-group 13,3%, video-group 16.7%) and upper rectum (lap-group 30.0%, video-group 16.7%), sigmoid and rectosigmoid (lap-group 28.4%, video-group 41.6%). the most performed surgery was abdominal rectosigmoidectomy (lap-group 27 cases, 45.0%; and video-group 33 cases, 55,0%), followed by right hemicolectomy (lap-group 16 cases, 26,6%; and video-group 13 cases, 21.7%). the extensions of the surgical specimens were greater in lap-group (mean 46.1 cm vs. 30.0 cm in video-group), but due to higher number of surgeries that resulted in longer specimens. when comparing same surgical techniques, the difference does not persist as in cases of retosigmoidectomy (lap-group with 32 cases, mean 28.2 cm; and video-group with 39 cases, mean 26.6 cm). with regard to tnm staging t3n0m0, tumors was the most common in lap-group with 30 cases (50.0%) and video-group with 35 cases (58.4%). regarding the lymph nodes count in surgical specimens, no difference was noted: total of 810 lymph nodes in specimens of lap-group with a mean of 13.5 nodes per specimen, and total of 862 lymph nodes in video-group with an average of 14.3 nodes per specimen. no difference was noted in relation to the count of lymph nodes in su

Abstract: Urinary tract infection (UTI) is a frequent pathology among HTLV-I+ individuals being capable of severely compromising the kidneys and bladder. Molecular characteristics of uropathogenic Escherichia coli (UPEC) from HTLV-I+ infected individuals are unknown. UPEC isolates from HTVL-I+ individuals, with and without clinical symptoms of myelopathy, were submitted to genetic typing seeking to infer bacterial diversity and potential virulence. 71 bacterial isolates were characterized according to random amplified polymorphic DNA and phylotypes. Phylotyping classified E. coli into four phylogenetic groups: A (18.3%), B1 (16.9%), B2 (39.4%), and D (25.3%) and 8 phylotypes according to the presence of the genetic sequences chuA, yjaA and the DNA fragment TSPE4.C2: (5.6%) and + (12.6%) in phylogroup A, + (7.0%) and ++ (9.8%) in B1, +++ (32.3%) and ++ (7.0%) in B2, + (15.4%) and ++ (9.8%) in D. The B2 phylogroup was the most prevalent among HTLV associated myelopathy and asymptomatic individuals. RAPD-PCR typing revealed a high degree of bacterial polymorphism indicating a non-clonal origin. Genotypes were not found to be distributed according to clinical status or epidemiological features. Our results lead us to suggest that the neurological impairment in HTLV-I+ individuals can be a risk factor for urinary infections due E. coli which are caused by distinct bacterial lineages.
