Deslocamento de abomaso em vacas leiteiras

The genetic selection and the nutritional management to improve milk production make the dairy cattle more susceptible to the development of diseases, such as the abomasal displacement. It is the most frequently detected abomasal problem and it is the main cause of abdominal surgeries in dairy cattle. It is a multifactorial disease that occurs mainly in dairy cattle of high production during the puerperium. The abomasal displacement can occur to the right (DAD) or to the left (DAE), being the former more frequent than the latter. It is related to feeding management and occurs in animals that also have other diseases such as hypocalcaemia, ketosis and retained placenta. The disease causes economical losses in dairy cattle because of the costs with treatment, reduction of production, increase of the interval between the parturition, loss of body weight, early discard of the matrix and mortality. The most usual clinical signs are apathy, dehydration, low to serious ruminal timpanismo (gas accumulation in the abomasum) with reduction or lack of motility, liquid splash sound during the ballottement of the right flank, metallic sound to percussion, presence of a structure similar to distended viscera in the thorax or in the paralombar cavity on the side corresponding to the displacement, and liquefied, dark, scarce and fetid feces. The treatment is surgical, and the most used technique is the omentopexy on the left flank. The hidroelectrolytic correction must be performed and the concomitant diseases must be treated. The prophylaxis consists of adequate nutrition and pre-parturition management, besides reduction of stress and other diseases of the puerperium

A relação entre a escola e a família do jovem: um estudo em duas escolas públicas

Faço parte do grupo de estudos sobre Jovens, Violência e Educação que desenvolve o estudo que procura compreender os modos de inserção da escola no bairro e os modos de inclusão dos jovens na comunidade e na própria escola. Os objetivos gerais do estudo são caracterizar os modos de inserção das escolas e dos jovens no bairro, o imaginário dos jovens sobre a escola, sobre seus projetos de vida e a prevenção da violência escolar. A participação neste grupo de pesquisa fez com que interesse se direcionasse à temática família, escola e comunidade. Assim sendo constituem-se objetivos específicos deste estudo: investigar a relação escola/família. Este estudo foi feito em duas escolas da periferia da cidade de Rio Claro- SP. Essas escolas atendem alunos moradores na região que pertencem aos extratos sócios econômicos mais baixos da população. O bairro é conhecido na cidade como violento, com ocorrências de assassinatos, tiroteios, brigas e presença do tráfico de drogas. Tanto é que este bairro é considerado área prioritária pela Prefeitura Municipal de Rio Claro – SP para intervenções que objetivem a prevenção da violência de jovens. Os dados coletados por meio de questionários e entrevistas foram pelo grupo com alunos do 8º ano e 9º ano do ensino fundamental e 1º ano do ensino médio. Esses dados serão analisados neste estudo

Ecologia molecular como ferramenta no estudo populacional do último megamamífero sulamericano: a anta (Tapirus terrestris) no Pantanal de Nhecolândia, MS

O presente estudo foi desenvolvido no Núcleo São Miguel Arcanjo do Parque Estadual Carlos Botelho, situado na Serra de Paranapiacaba, região sudeste do estado de São Paulo, Brasil. Quantificaram-se os regenerantes lenhosos ≤ 10 cm de altura sob interferência da cobertura de Calathea communis Wanderley & S. Vieira (Maranthaceae), envolvendo os ambientes de encosta e fundo de vale, em três períodos: junho e outubro de 2011, assim como em fevereiro de 2012. Foram utilizados os parâmetros de densidade, sobrevivência e colonização (input) para a caracterização da regeneração. No sorteio dos pontos de amostragem, cada um de 6transectos (aproximadamente 1 Km de extensão) foi sub-dividido em 20 frações de 50 metros, sendo sorteados 10 pontos por transecção. Do total de 120 parcelas (1X1m) que amostraram as plântulas, 60 localizaram-se em ambiente de fundo de vale e 60 na encosta, sendo que em cada condição topográfica 30 parcelas foram montadas sob a cobertura de C.communis e 30 na sua ausência. Os dados foram discutidos com base na aplicação de uma análise de variância fatorial, associada ao teste de Tukey de comparação de médias “a posteriori”. Observou-se que, para a densidade, a presença e ausência de Calathea communis geraram diferenças significativas (p≤0,05) nos períodos de outubro/2011 e fevereiro/2012, no entanto, para os ambientes topográficos só ocorreu variação significativa da densidade no período de fevereiro/2012. Quanto à sobrevivência, as diferenças significativas foram relacionadas à topografia, mas apenas no período de fevereiro/2012. Considerando-se os valores de input, estes foram maiores nas parcelas situadas em fundo de vale e em condições de ausência de Calathea, embora tais diferenças não sejam significativas (p≥0,05), segundo indicações da análise de variância

Vitamin D serum levels are associated with handgrip strength but not with muscle mass or length of hospital stay after hip fracture

Objectives: The aim of this study was to evaluate the association between serum levels of 25(OH) vitamin D-3 with midupper arm muscle circumference (MUAMC), handgrip strength and length of hospital stay (LOS) after hip fracture.Methods: In total, 102 consecutive patients with hip fracture over the age of 65 were admitted to the orthopedic unit and prospectively evaluated. All of the patients were treated according to specific protocols depending on the type of fracture. Anthropometric measurements and handgrip strength were performed, and blood samples were taken for serum biochemistry and 25(OH) vitamin D-3 analysis within the first 72 h of admission. All of the patients were followed during their hospital stay, and the length of stay was recorded.Results: Of the patients, two were excluded because of pathologic fractures. In total, 100 patients with a mean age of 80 +/- 7 y were included in the analysis. Among these patients, 73% were female, and 37% had vitamin D deficiency. The median LOS was 7 (5-11) d. Patients with vitamin D deficiency had lower handgrip strength in univariate analysis. In the multiple linear regression analysis with robust standard error, serum vitamin D levels adjusted by age and sex were associated with handgrip strength but not with MUAMC and LOS after hip fracture.Conclusions: In conclusion, vitamin D serum levels were associated with handgrip strength but not with muscle mass or length of hospital stay after hip fracture.

Effects of castration and of testosterone replacement on alpha(1)-adrenoceptor subtypes in the rat vas deferens

The contractions of the rat vas deferens in response to noradrenaline are mediated through alpha(1A)-adrenoceptors. We observed participation of alpha(1B)-adrenoceptors in these contractions after castration. We now investigated the time course of this plasticity and the effects of testosterone by determining the actions of competitive antagonists on noradrenaline-induced contractions after 7, 14, 21 and 30 days of castration. BMY 7378 (8-[2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl]-8-azaspiro[4.5]decane-7,9-dione dihydrochloride) antagonised noradrenaline-induced contractions in control and castrated rats with low pA(2) values (approximately = 6.8). In control vas deferens, WB 4101 (2-(2,6-dimethoxyphenoxyethyl)aminomethyl-1,4-benzodioxane hydrochloride) had a slope in the Schild plot no different from 1.0, while slopes lower than 1.0 (approximately 0.6) were observed for vas deferens from castrated rats. Chloroethylclonidine was ineffective in the control vas while it inhibited noradrenaline-induced contractions in vasa from castrated rats and converted the complex antagonism by WB 4101 into simple competitive antagonism. Treatment of castrated rats with testosterone prevented the effects of castration. The results suggest that alpha(1B)-adrenoceptors are detectable in vas deferens from at least the 7th through the 30th day after castration and that testosterone prevents this plasticity.

Inhibition of diethylnitrosamine-initiated alcohol-promoted hepatic inflammation and precancerous lesions by flavonoid luteolin is associated with increased sirtuin 1 activity in mice

Chronic and excessive alcohol consumption is an established risk for hepatic inflammation and carcinogenesis. Luteolin is one of the most common flavonoids present in plants and has potential beneficial effects against cancer. In this study, we examined the effect and potential mechanisms of luteolin supplementation in a carcinogen initiated alcohol-promoted pre-neoplastic liver lesion mouse model. C57BL/6 mice were injected with diethylnitrosamine (DEN) [i.p. 25 mg/kg of body weight (BW)] at 14 days of age. At 8 weeks of age mice were group pair-fed with Lieber-DeCarli liquid control diet or alcoholic diet [ethanol (EtOH) diet, 27% total energy from ethanol] and supplemented with a dose of 30 mg luteolin/kg BW per day for 21 days. DEN-injected mice fed EtOH diet displayed a significant induction of pre-neoplastic lesions, a marker associated with presence of steatosis and inflammation. Dietary luteolin significantly reduced the severity and incidence of hepatic inflammatory foci and steatosis in DEN-injected mice fed EtOH diet, as well the presence of preneoplastic lesions. There was no difference on hepatic protein levels of sirtuin 1 (SIRT1) among all groups; however, luteolin supplementation significantly reversed alcohol-reduced SIRT1 activity assessed by the ratio of acetylated and total forkhead box protein O1 (FoXO1) and SIRT1 target proliferator-activated receptor gamma, coactivator 1 alpha (PGC1α). Dietary intake of luteolin prevents alcohol promoted pre-neoplastic lesions, potentially mediated by SIRT1 signaling pathway.
