Exercise increases the angiotensin II effects in isolated portal vein of trained rats

Training in rats adapts the portal vein to respond vigorously to sympathetic stimuli even when the animal is re-exposed to exercise. Moreover, changes in the exercise-induced effects of angiotensin II, a potent venoconstrictor agonist, in venous beds remain to be investigated. Therefore, the present study aimed to assess the effects of angiotensin II in the portal vein and vena cava from sedentary and trained rats at rest or submitted to an exercise session immediately before organ bath experiments. We found that training or exposure of sedentary animals to a single bout of running exercise does not significantly change the responses of the rat portal vein to angiotensin II. However, the exposure of trained animals to a single bout of running exercise enhanced the response of the rat portal vein to angiotensin II. This enhancement appeared to be territory-specific because it was not observed in the vena cava. Moreover, it was not observed inendothelium-disrupted preparations and in preparations treated with Nω-nitro-l-arginine methyl esterhydrochloride, indomethacin, BQ-123 or BQ-788. These data indicate that training causes adaptations in the rat portal vein that respond vigorously to angiotensin II even upon re-exposure to exercise. This increased response to angiotensin II requires an enhancement of the vasocontractile influence of endothelin beyond the influence of nitric oxide and vasodilator prostanoids.

Embolization of splenorenal shunt associated to portal vein thrombosis and hepatic encephalopathy

Hepatic encephalopathy (HE) is a cognitive disturbance characterized by neuropsychiatric alterations. It occurs in acute and chronic hepatic disease and also in patients with portosystemic shunts. The presence of these portosystemic shunts allows the passage of nitrogenous substances from the intestines through systemic veins without liver depuration. Therefore, the embolization of these shunts has been performed to control HE manifestations, but the presence of portal vein thrombosis is considered a contraindication. In this presentation we show a cirrhotic patient with severe HE and portal vein thrombosis who was submitted to embolization of a large portosystemic shunt. Case report: a 57 years-old cirrhotic patient who had been hospitalized many times for persistent HE and hepatic coma, even without precipitant factors. She had a wide portosystemic shunt and also portal vein thrombosis. The abdominal angiography confirmed the splenorenal shunt and showed other shunts. The larger shunt was embolized through placement of microcoils, and the patient had no recurrence of overt HE. There was a little increase of esophageal and gastric varices, but no endoscopic treatment was needed. Since portosystemic shunts are frequent causes of recurrent HE in cirrhotic patients, portal vein thrombosis should be considered a relative contraindication to perform a shunt embolization. However, in particular cases with many shunts and severe HE, we found that one of these shunts can be safely embolized and this procedure can be sufficient to obtain a good HE recovery. In conclusion, we reported a case of persistent HE due to a wide portosystemic shunt associated with portal vein thrombosis. As the patient had other shunts, she was successfully treated by embolization of the larger shunt. (C) 2014 Baishideng Publishing Group Inc. All rights reserved.

Portal hypertension in dogs

Portal hypertension (PH) is the pathological increase in portal vein pressure above normal limits. Two variables control the pressure in the portal system: the resistance to blood flow and blood flow volume in the portal system. If one these variables changes, PH may develop. Classification: Pre-hepatic (e. g. compression of the portal vein), intrahepatic (e. g. chronic hepatitis and cirrhosis) or post-hepatic (e. g. right heart failure). The invasive methods (intravenous catheter) were replaced by an indirect method of diagnosis: Doppler Ultrasound. This technique does not measure portal pressure, but indirectly allows the diagnosis of PH. Average speed of portal flow decrease (<10 cm/s) and hepatofugal flow have been reported in cirrhotic dogs with PH. Currently, the focus of the ultrasound is the detection of acquired collateral portal circulation (ACPC), closely correlated with hepatic encephalopathy. The characterization of these vessels is essential to differentiate them from congenital shunts. They are usually multiple vessels, small and tortuous, with turbulent flow, near to the kidneys, and/or a single and larger vessel, draining into the left renal vein (dilated gonadal vein). Gastric, esophageal and mesenteric varices may occur. After identifying the PH, it is important to determine its origin in order to treat the underlying disease. B-Mode Ultrasound and Doppler are the best choices in cases of suspected PH, because they may recognize not just the hypertension, but also its complications and origin.

It's the freedom to know and traveling around the city in a simple and trivial way. It is a new trend, the future of Web systems development

Preposições em textos do gênero notícia na imprensa paulista: norma e uso no ínicio do século XX

This paper proposes a reflection on processes of variation and change that occurred with the portuguese prepositions a, ate, em and para, taken as a parameter for answers in a broader context, the confrontation between the norm and use and between standard and linguistic variation. We conducted the study based on a corpus composed of all occurrences of the prepositions in question removed news of the newspaper O Combate and O Estado de Sao Paulo. Whereas the main objective of the study is to present and describe the use of these particles in newspaper articles of the Imprensa Paulista, data were collected and quantified by using the statistical package GOLDVARB, and interpretation of results relied (i) assumptions regarding the process variation in the use of prepositions and prepositions replace weak, as the preposition to, for strong prepositions (para, em, até), (ii) in comparison with the grammatical rule in effect at the time, (iii) and in the search for the existence of some historical factor that justifies the selection of a preposition rather than another. Among the hypotheses, we investigate the relationship between these prepositions and whose kind of preachers they introduce supplements: the direction of motion (abstract or concrete) or transfer (material and verbal / perceptual). This theoretical perspective was the Labovian sociolinguistics (Labov, 1972, 1994), which defines the linguistic variable as a representation of two or more different ways to convey a certain information content, being necessary to define it the following criteria set exact number of variants to establish all the multiplicity of contexts in which it appears; develop a quantitative index for measuring the values of variables

Jornalismo econômico como exercício da cidadania: uma análise da divulgação econômica na mídia oficial e nos veículos Universo Online e O Estado de São Paulo

The present study had the intention to demonstrate how the language used by official sources of economy helps to keep the limitation and lack of accessibility of economic journalism to non-specialist readers. Over two weeks, we compared the disclosures in the economics editorial office of the site Universo Online and the newspaper O Estado de S. Paulo to those cited in official reports. From this analysis of more than 50 issues selected for the sample, was observed how the technical language used by the official press makes more difficult the access to information and citizenship. Besides the comparison and description of the reports, the study involved the content analysis employed in the media. It was noted the presence of biased approaches and materials poorly cleared. The language used in many cases was not appropriate to the type of audience for which the news was heading. One of the most serious problems, perhaps, was the copy and paraphrase of press releases. The reports, most are limited to the specialist showed, contrary to the duty of public transparency, while highlighting the problems, the study also showed well-written texts that indicate a promising future for citizen and economic journalism
