Caracterização físico-química de frutos de umbuzeiro para consumo in natura em dois estádios de maturação.

O Banco Ativo de Germoplasma (BAG) de umbus (Spondias tuberosa Arruda) da Embrapa Semiárido possui 200 genótipos que representam a variabilidade genética da espécie no semiárido brasileiro, apresentando frutos com diferentes tamanhos, teores de açúcares, vitamina C, acidez, entre outras características de interesse. Por este motivo, objetivou-se com esse trabalho, avaliar a qualidade físico-química de frutos de umbuzeiros do BAG da Embrapa Semiárido, visando identificar genótipos com potencial para o consumo in natura e/ou processamento. Utilizou-se delineamento fatorial 6x2, sendo 6 genótipos e 2 estádios de maturação, com 4 repetições e 5 frutos por repetições. Os genótipos utilizados foram: BGU37, BGU44, BGU48, BGU52, BGU55 e BGU68; e dois estádios de maturação: frutos ?inchados? e frutos totalmente maduros. Determinou-se os sólidos solúveis (SS), a acidez titulável e a relação SS/AT dos frutos. De acordo com os resultados, os genótipos avaliados apresentaram altos teores de SS e AT, sendo os genótipos BGU44 e BGU48 os mais indicados para o consumo in natura e processamento, pois apresentaram a maior relação SS/AT no estádio de maturação ?inchado?.Para frutos em estádio maduro, os genótipos BGU37 e BGU52 são os mais adequados, devido ao maior valor de sólidos solúveis

Effect of the intracerebroventricular administration of GR 113808, a selective 5-HT4 antagonist, on water intake during hyperosmolarity and hypovolemia

We demonstrate here that acute third ventricle injections of GR 113808, a highly selective 5-HT4 antagonist, decrease water intake induced by a previous salt load while potentiating drinking elicited by hypovolemia induced by previous subcutaneous administration of polyethylene glycol in male Wistar rats (200 ± 20 g). At the dose of 160 nmol/rat, third ventricle injections of GR 113808 induced a significant reduction of water intake in salt-loaded animals after 120 min as compared to salt-loaded animals receiving third ventricle injections of saline (salt load + GR = 3.44 ± 0.41 ml, N = 12; salt load + saline = 5.74 ± 0.40 ml, N = 9). At the dose of 80 nmol/rat, GR 113808 significantly enhanced water intake in hypovolemic animals after 120 min as compared to hypovolemic animals receiving third ventricle injections of saline (hypovol + GR = 4.01 ± 0.27 ml, N = 8; hypovol + saline = 2.41 ± 0.23 ml, N = 12). We suggest that central 5-HT4 receptors may exert a positive drive on water intake due to hyperosmolarity and a negative input on drinking provoked by hypovolemia

Changes in Adolescents' Oral Health Status: Responsiveness of the Child Perception Questionnaire 11-14.

Changes in oral health status following treatment should be assessed clinically as well as by patients' reported outcomes. This study investigated changes on oral-health-related quality of life (OHRQoL) of adolescents enrolled in a comprehensive oral health care program for caries and gingival conditions. The sensitivity of the Child Perception Questionnaire11-14 (CPQ11-14) to detect clinical changes, that is, its responsiveness, was assessed. A total of 618 10-15-year adolescents answered the questionnaire before treatment and 560 at follow-up after 1 year. In the follow-up, 2 additional global transition judgment questions were asked. The adolescents were clinically and radiographically examined. At the baseline, 374 adolescents needed only nonoperative treatment, whereas 274 needed non- and operative treatments. After 1 year, the adolescents were regrouped according to the fulfillment of their treatment needs in Group 1 (n = 363) needing/receiving nonoperative treatment only; Group 2 (n = 98) needing/receiving both non- and operative treatments; Group 3 (n = 99) receiving nonoperative treatment only, while needing also operative treatment. The CPQ11-14 total mean change scores by the global transition judgment on self-perceived oral health status indicated significant differences (p < 0.001, ANOVA; internal responsiveness). The effect of the program for the treatment groups was significant (p = 0.014, ANCOVA; external responsiveness). The effect size for the change scores was of moderate magnitude. In conclusion, an overall improvement of adolescents' OHRQoL was observed following 1-year oral health care program for caries and gingival conditions. The CPQ11-14 was internally and externally sensitive to detect substantial clinical changes. The CPQ11-14 seems appropriate for measuring long-term changes on adolescents' OHRQoL
