O suco de laranja é um alimento rico em substâncias antioxidantes, como os flavonoides cítricos, vitamina C e carotenoides, que podem reduzir o estresse oxidativo que está relacionado à gênese das doenças cardiovasculares, diabetes e câncer. No entanto, o processamento da laranja para obtenção do suco interfere no tipo e quantidade dos compostos antioxidantes, podendo comprometer as ações esperadas. O objetivo deste trabalho foi avaliar a atividade antioxidante do suco de laranja, comparando os resultados após a ingestão aguda do suco de laranja fresco e do suco de laranja pasteurizado comercialmente em indivíduos adultos saudáveis. Cada voluntário foi submetido a dois tratamentos: ingestão aguda de suco de laranja fresco e, após intervalo de 30 dias, ingestão aguda de suco de laranja pasteurizado. Nos dois tratamentos foram colhidas amostras de sangue dos indivíduos antes e após a ingestão do suco de laranja. O efeito antioxidante total foi mensurado pelo ensaio do radical ABTS+ (2,2'azinobis (3-etilbenzenotiazolina 6-sulfônico) e pelo ensaio de TBARS (substâncias reativas ao ácido tiobarbitúrico) nas amostras de sangue. Observou-se um aumento de 2,2% na capacidade antioxidante do sangue a partir de 4 horas após a ingestão do suco de laranja fresco e que se manteve estável até 24 horas do consumo (p<0.05). Já com a ingestão do suco de laranja pasteurizado, a capacidade antioxidante se manteve estável e equivalente ao suco de laranja fresco nas primeiras 4 horas, mas aumentou 1,4% após 8 horas, permanecendo neste nível até as 24 horas seguintes (p<0.05). Após a ingestão do suco fresco, os níveis de peroxidação lipídica, diminuíram 27% nas primeiras 4 horas. Porém, a partir das 8 h retornaram ao valor inicial. Os resultados após o consumo do suco pasteurizado mostraram uma redução da peroxidação lipídica em 18% a partir das 4 horas e 8 h (p<0.05), e esta redução se acentuou (27%) às 24 h ...

Objective: To assess the attitudes and knowledge about hepatitis by scholars and dental practitioners from Recife and its metropolitan region. Method: The research protocol was submitted and approved by the Ethics and Human Research Committee of the Federal University of Pernambuco. There were included 230 undergraduate students in dentistry and 104 dentists who exercise their professional activity in Recife and its Metropolitan Region. They signed a consent form and answered a questionnaire, the evaluative instrument, with objective questions about biosafety, transmission of hepatitis and sexually transmitted diseases. Results: About the types of hepatitis 133 (57.8%) students and 61 (58.7%) professionals claimed to know the types A, B and C. Concerning transmission 31 (13.5%) students and 25 (24.0%) professionals said that the main route of transmission were sexual and bloodstream respectively. Relating to imunization 221 (96.1%) students and 99 (95.2%) professionals reported that have been vaccinated against hepatitis B, however, only 126 (54.8%) students and 55 (52.9%) professionals have followed the immunization’s schema. Regarding the cleaning of the office equipment, 18.7% of the students replied that they do not know who does it. 56.7% of professionals said that it was performed with alcohol 70 ° GL.Conclusions: The findings indicate that there is a concern for biosafety but the knowledge about the forms of hepatitis transmission and biosecurity measures need to be better settled.

A case report of a patient who presents as chief complaint presence of stained restorations in the anterior teeth. After analysis and discussion of the clinical therapeutic approaches to be adopted, it was observed the presence of type class IV restorations on teeth 11 and 21, due to an oblique coronal fracture in the past. But the patient was not satisfied with the aesthetic result, then where was planned the realization of the removal of the restorations, for subsequently be used direct restorative materials for the correction of form, function and esthetics. The final result showed that the restorations were able to return the form, function and aesthetic dental, thereby evidencing the proven development of restorative dentistry in the solution of aesthetic problems.

The aim of the present study was to verify, through the response surface methodology, the optimum conditions for the combined use of aqueous extract of white lupine (Lupinus albus L.) and tropical pitanga juice (Eugenia unifl ora L.) in the development of a drink. Therefore, the independent variables were represented by the volume of aqueous extract of lupine (mL) and by the volume of pitanga juice (mL). The dependent variables (responses) were obtained through sensory test of acceptance (“appearance”, “aroma”, “taste” and “overall acceptability”). The combined optimization of the variables pointed the second formulation (50mL of aqueous extract of lupine and 30mL of pitanga juice) of the experimental project as the most adequate. In conclusion it was possible to get a drink with attractive sensory characteristics using aqueous extract of white lupine and tropical pitanga juice. The usage of response surface methodology made possible the determination of regions of maximum acceptance for each attribute evaluated in the formulation of a drink with aqueous extract of white lupine and pitanga juice, with a minimum of tests.

Infection with hepatitis C virus is a worldwide public health problem it affects about 170 to 250 million people worldwide may lead to complications such as cirrhosis and hepatocellular carcinoma. Patients with chronic hepatitis C most often is inadequate nutrient intake, macro and micronutrients, which induces changes in nutritional status and lipid profi le. Supplementation with vitamin C has shown benefi t. Limited information is available on levels of vitamin C in this type of illness. The study aimed to evaluate the effect of regular intake of orange juice on the nutritional and dietetic of patients with chronic hepatitis C infection. The study enrolled 23 patients volunteers, 13 men and 10 women treated at the Special Health Service of Araraquara (SESA). They consumed for 8 weeks 500 mL.d-1 of pasteurized orange juice. At baseline and after 8 weeks of juice intake the patients were evaluated for anthropometric parameters. The dietary intervention with 500 mL.d-1 with orange juice during the 8 weeks did not alter the nutritional status of patients.
