Metabolismo oxidativo e card��aco de equinos submetidos a exerc��cio de baixa intensidade antes e ap��s suplementa����o com antioxidante

The present study aimed to evaluate cardiac and lipoperoxidation markers in horses subjected to low intensity and long duration (TLD) exercise test, before and after vitamin E supplementation. For this purpose, 10 horses were used, subjecting them to the first TLD with a workload based on individual maximal oxygen uptake (VO2max). Then, horses received vitamin E (dl-alpha-tocopherol) during 59 days at a daily oral dose of 1,000IU, and thereafter they performed a second TLD with the same protocol as the first. Blood samples were collected to determine plasma malondialdehyde (MDA) as an index of lipoperoxidation, serum cardiac troponin I (cTnI) and creatine kinase MB isoenzyme (CK-MB) as cardiac markers. As a result of the exercise, there was no significant increase in MDA or cTnI, but serum CK-MB increased suggesting myocardial stress. The supplementation was able to minimize reactive oxygen species production, as evidenced by lower concentrations of MDA at all times evaluated, but it didn't cause protective effect on the myocardium. It was concluded that the low intensity and long duration exercise promoted light myocardial stress in horses and vitamin E supplementation reduced lipoperoxidation.

Metabolismo da videira ���syrah��� no semi��rido nordestino sob tr��s estrat��gias h��dricas

The almost complete absence or misdistribution of water as a natural resource frequently constitute a limiting factor for plant growth and development in the semi-arid northeastern Brazil. In this context, the use of appropriate irrigation techniques is an essential and indispensable factor for proper functioning of the primary and secondary metabolisms in plants. This study aimed to assess the metabolism of the Syrah grapevine in the semi-arid northeastern Brazil, by using three irrigation strategies (controlled deficit irrigation [CDI], deficit irrigation [DI], and full irrigation [FI]). The research was conducted at Embrapa Semiarid (Embrapa-Brazilian Agricultural Research Corporation), Experimental Field of Bebedouro, municipality of Petrolina, state of Pernambuco, Brazil. The statistical design was randomized blocks, with a 3 x 6 factorial scheme. Six samplings were performed throughout the experiment cycle at 54, 60, 73, 87, 101, and 115 days after pruning (DAP). We analyzed the total soluble sugars, reducing sugars, total soluble protein, and invertase activity. Analysis of variance and the F test were performed for all analyzed variables. The means were compared using the Tukey test at 5% significance. At the end of the experiment cycle, DI was found to increase the average acid invertase activity in the plant cell wall. Further, by the end of the experiment cycle, the total soluble sugars and reducing sugars increased in all plants in the three irrigation strategies. Thus, we conclude that it is possible to reduce water consumption in vineyards of the semi-arid northeastern Brazil, without significantly affecting the protein and sugar metabolisms in the plants.

Uso da entrevista em disserta����es e teses produzidas em um programa de p��s-gradua����o em educa����o

The interview has been a widely used procedure of research in humanities. Despite the frequent use, researches are not always supported in the literature on research methodology. The aim of this study was to analyze how the interview was used in dissertations and theses in a graduate Program in Education at a university in Sao Paulo state. This study examined 167 final papers developed in to period of five years. Variables focused were: justification for the use of interview, type of interview used, guide elaboration and adaptation, kind of analysis, among others. The results showed that it is still necessary to incorporate the contents of the research methodology underlying the use of the interview to achieve the scientific rigor for this procedure.

Mobili��rios adaptados para pessoas com paralisia cerebral: um levantamento das teses e disserta����es produzidas no Brasil

The Assistive Technology makes the lives of people without disabilities more practical, but for people with disabilities it can make things possible. For these individuals can provide the conditions, making their limitations are not obstacles to their social and personal empowerment, and may contribute to their effective participation in tasks that were previously impossible, such as remaining seated correctly. A segment on which the necessary assistive technology works, is the adaptation of furniture such as chairs, tables, chairs-to-wheels for individuals with disabilities, as well as cerebral palsy. The study aimed to conduct a survey and brief description of theses and dissertations produced in Brazil on furniture adapted for students with cerebral palsy. We made searching in databases of libraries of major universities and federal state national banks, theses and dissertations. Nine studies were selected for description. It was concluded that there is a considerable array of professionals, both in engineering as the field of rehabilitation, to contribute in the adaptation, creation and even the manufacture of furniture for children with cerebral palsy and that the securities most studied are the chairs and their components.

Estresse oxidativo, altera����es metab��licas e renais decorrentes da elevada ingest��o de sacarose: efeito protetor da N-acetilciste��na (NAC)

Oxidative stress is related with physiopathology of diabetes mellitus type II and with its secondary complications, such as diabetic nephropathy. Thus, the purpose of this study was to examine the effects of n-acetylcysteine NAC, an antioxidant from Allium cepa, on oxidative stress, morphometrical and nutritional parameters and basal metabolism and energetic substrate utilization, serum glucose and oral glucose tolerance test (OGTT), and renal function of high-sucrose intake rats. Animals were initially divided into three groups. Rats in the control group (C; n=10) were given free access to a standard chow and water; (S; n=10) group received standard chow and 30% sucrose in its drinking water; (SN; n=5) group received standard chow and 2g/L NAC and 30% sucrose in its drinking water. After 25 days of treatments, rats were submitted to indirect calorimetry in fasted and feed states. After 30 days of treatments, rats from C and S groups were divided into four groups of five rats each. The (CC) and (SS) groups were given an intra-gastric dose 0,6mL saline (0,9%NaCl) and the (CNAC) and (SNAC) groups were treated with a intra-gastric dose of 0,6mL NAC (160g/day), and then everybody received a intra-gastric dose of glucose solution (20%) for the OGTT. Animals of S and SN groups have higher liquid consumption and lower food consumption than C group. Calorimetric analyses confirm that despite of the final body weight had not statistical difference among groups, S group have lower resting metabolic rate when compared to C and SN animals. Besides, S group has higher respiratory quotient, higher carbohydrate oxidation and lower lipid oxidation, both in fasted and feed states, than C and SN groups, evidencing the beneficial effect of NAC. Fasting plasma glucose is increased in SS and SNAC animals when compared to CC and CNAC, however SN group has glicemic level at 30 min before OGTT decreased when ...(Complete abstract click electronic access below)

Spirulina e exerc��cio f��sico no controle do metabolismo muscular da glicose em ratos diab��ticos

O Diabetes mellitus �� um problema de sa��de p��blica mundial. Tal doen��a �� caracterizada pela redu����o da secre����o (Diabetes mellitus tipo1) ou da a����o (Diabetes mellitus tipo2) da insulina, acarretando hiperglicemia, al��m de altera����es no metabolismo das prote��nas e dos lip��deos. As consequ��ncias para o organismo s��o variadas, incluindo hipertens��o, nefropatias, retinopatias e cardiopatias. Atualmente existe grande interesse nas ervas medicinais, como hipoglicemiantes naturais, entre elas, a spirulina. A spirulina parece ser boa fonte prot��ica para a alimenta����o, tem boa aceita����o e n��o apresenta efeitos t��xicos aparentes. Al��m disso, ela pode exercer efeitos ben��ficos no tratamento de algumas doen��as como c��ncer, desnutri����o, obesidade, hipercolesterolemia, hipertens��o arterial, diabetes mellitus,entre outras. Tendo em vista a grande possibilidade utilizar a spirulina na dieta, o presente estudo visa analisar o metabolismo muscular da glicose em ratos diab��ticos. N��o foram encontradas diferen��as significativas entre os grupos nas vari��veis metab��licas estudadas
