Antioxidant And Anti-diabetic Potential Of Passiflora Alata Curtis Aqueous Leaves Extract In Type 1 Diabetes Mellitus (nod-mice).

Leaves of Passiflora alata Curtis were characterized for their antioxidant capacity. Antioxidant analyses of DPPH, FRAP, ABTS, ORAC and phenolic compounds were made in three different extracts: aqueous, methanol/acetone and ethanol. Aqueous extract was found to be the best solvent for recovery of phenolic compounds and antioxidant activity, when compared with methanol/acetone and ethanol. To study the anti-inflammatory properties of this extract in experimental type 1 diabetes, NOD mice were divided into two groups: the P. alata group, treated with aqueous extract of P. alata Curtis, and a non-treated control group, followed by diabetes expression analysis. The consumption of aqueous extract and water ad libitum lasted 28 weeks. The treated-group presented a decrease in diabetes incidence, a low quantity of infiltrative cells in pancreatic islets and increased glutathione in the kidney and liver (p<0.05), when compared with the diabetic and non-diabetic control-groups. In conclusion, our results suggest that the consumption of aqueous extract of P. alata may be considered a good source of natural antioxidants and compounds found in its composition can act as anti-inflammatory agents, helping in the control of diabetes.

Delivery Of A Urology Online Course Using Moodle Versus Didactic Lectures Methods.

To subjectively and objectively compare an accessible interactive electronic library using Moodle with lectures for urology teaching of medical students. Forty consecutive fourth-year medical students and one urology teacher were exposed to two teaching methods (4 weeks each) in the form of problem-based learning: - lectures and - student-centered group discussion based on Moodle (modular object-oriented dynamic learning environment) full time online delivered (24/7) with video surgeries, electronic urology cases and additional basic principles of the disease process. All 40 students completed the study. While 30% were moderately dissatisfied with their current knowledge base, online learning course delivery using Moodle was considered superior to the lectures by 86% of the students. The study found the following observations: (1) the increment in learning grades ranged from 7.0 to 9.7 for students in the online Moodle course compared to 4.0-9.6 to didactic lectures; (2) the self-reported student involvement in the online course was characterized as large by over 60%; (3) the teacher-student interaction was described as very frequent (50%) and moderately frequent (50%); and (4) more inquiries and requisitions by students as well as peer assisting were observed from the students using the Moodle platform. The Moodle platform is feasible and effective, enthusing medical students to learn, improving immersion in the urology clinical rotation and encouraging the spontaneous peer assisted learning. Future studies should expand objective evaluations of knowledge acquisition and retention.

O desenvolvimento do texto dissertativo em crianças da 4ª série

This reaserch analysed the developmental stage of fourth grade (primary school) children in ability of writting argumentative texts joint with their context. The reason of this reaserch is the lack of new studies in linguistical area and high ratio of unable students to make this kind of text. It will be showed the analysis of making text by public schools children for three months. These data were analysed trying identify argumentative operators, the kinds of arguments used and the stage of the argumentative ability of these children. The study showed that the introduction of argumentative text in first grades give them more chances of succeed, preparing these pupils in their finishing high school. This fact obviously will make easier the development of their critical point of view, helping the students to think about their living social reality.

Sistema de sincronismo entre a colhedora de cana-de-açúcar e o veículo de transbordo

One of the problems found in mechanical harvest of sugar cane is the lack of synchronism between the harvest machine and the infield wagon, causing crop losses as well as operational capacity. The objective of the present research was to design a system capable of helping to synchronize the sugar cane harvest machine with the wagon. The communication between tractor and harvest machine is wireless. Two ultrasound sensors coupled to the elevator and a microprocessor manage such information, generating a correct synchronization among the machines. The system was tested in laboratory and on field performing its function adequately, maintaining the two machines in synchronization, indicating and alerting the operators their relative positions. The developed system reduced the sugar cane lost in 60 kg ha-1 comparing to the harvest with the system turned off.

Qualidade pós-colheita de caqui 'fuyu' com utilização de diferentes concentrações de cobertura comestível

One of the main objectives of applying edible coatings on fruits surface is to create a protective film to reduce weight loss due to evaporation and transpiration and also to decrease the risk of fruit rot caused by environmental contamination, in order to improve the visual aspect. Therefore, it is possible to increase shelf life, and decrease post harvest losses. Persimmon is a much appreciated fruit, with high potential for export, but sensitive to handling and storage. This study aimed to evaluate the effect of applying the edible coating Megh Wax ECF-124 (18% of active composts, consisting of emulsion of carnauba wax, anionic surfactant, preservative and water) produced by Megh Industry and Commerce Ltda in three different concentrations (25, 50 and 100%) on post harvest quality of 'Fuyu' persimmon stored for 14 days. The attributes evaluated for quality were: firmness, pH, acidity, soluble solids, weight loss and color. The results showed that application of carnauba wax in different concentrations was effective on decreasing weight loss of persimmon cv. Fuyu and maintenance of color aspects. Treatment at lower concentration, 25%, showed lower rate of discharge, but high concentrations showed lower values of mass loss. Carnauba wax application showed a high potential for use on postharvest conservation, and can be applied together with other technologies, helping to maintain quality for export.

Aceitação-rejeição para estudar e agressividade na escola

The relationship between aggressiveness and peer acceptance-rejection were analyzed in 1281 elementary school children. Sociometric measure was based on three positive and three negative classmates choices. The aggressiveness scales gathered information about familiar, scholar and general situations. There were no statistically insignificant differences among the schools related to the sociometric and aggressiveness in familiar situation measures. The scales of the scholar and general aggressiveness formed two sub-groups, in which two schools showed less aggressiveness and the two other more aggressiveness. Scholar aggressiveness showed significant correlations with the sociometric status in all schools and the general aggressiveness in one of them, suggesting that the most social acceptance, the lesser the student's aggressiveness. As the correlations were low, extreme groups in acceptance-rejection conditions had been studied and the scales of scholar and general aggressiveness had differentiated these groups in only one school.

Metformina interage com o treinamento físico diminuindo a glicemia e aumentando o armazenamento de glicogênio em ratos diabéticos

INTRODUCTION: Like in humans, lower amounts of glycogen are present in tissues of diabetic rats. However, training or drugs that lower glycemia can improve the metabolic control. Metformin increased glycogen while decreased glycemia in normal rats stressed by exercise. OBJECTIVE: In this work we investigated if regular exercise and metformin effects improve the metabolism of diabetic rats. METHODS: Alloxan diabetic Wistar rats treated with metformin (DTM) or not (DT) were trained. Training consisted of 20 sessions of 30 min, 5 days a week. Sedentary diabetic rats served as control (SD and SDM). Metformin (5.6 µg/g) was given in the drinking water. After 48 h resting, glucose (mg/dl) and insulin (ng/mL) was measured in plasma and glycogen (mg/100 mg of wet tissue) in liver, soleus and gastrocnemius. RESULTS: Glycemia decreased in DM group from 435±15 to 230±20, in DT group to 143±8.1 and in DTM group to 138±19 mg/dl. DM group had proportional increase in the hepatic glycogen from 1.69±0.22 to 3.53±0.24, and the training increased to 3.36 ± 0.16 mg/100 mg. Metformin induced the same proportional increase in the muscles (soleus from 0.21±0.008 to 0.42±0.03 and gastrocnemius from 0.33±0.02 to 0.46±0.03), while the training promoted increase on gastrocnemius to 0,53 ± 0,03, only. A high interaction was observed in liver (glycogen increased to 6.48±0.34). CONCLUSION: Very small oral doses of metformin and/or, partially restored glycemia in diabetic rats and decreased glycogen in tissues. Its association with an exercise program was beneficial, helping lower glycemia further and increase glycogen stores on liver of diabetic rats.
