RESUMO

The objective of this study was to determine if the combined effect of ewe grazing and the incorporation of sage by-products in the lamb feed enhances the Segureña ewe and lamb antioxidant status. For that, the endogenous (related to blood antioxidant enzymes) and exogenous (plasma antioxidant activity) antioxidant systems of ewes and lambs were studied at the physiological stages of lactation, after weaning and at the end of the fattening period. Major results indicated that grazing improved the enzymatic antioxidant defense of ewes during the stressful period of lamb weaning, and also, the antioxidant status of the ewe plasma at both physiological stages: lactation and after lamb weaning. With regards to the lambs, ewe grazing stimulated the antioxidant enzymatic defense during lactation, but not the antioxidant capacity of the plasma. At the end of the fattening period, the inclusion of sage by-products in the lamb diet (10% w/w) enhanced both the enzymatic cascade and antioxidant capacity of the lamb plasma. The antioxidant capacity of the lamb meat was also studied and the benefits of sage were detected in samples from the deltoideus muscle. Thus, Mediterranean grazing stimulated the antioxidant defense in ewes, while the inclusion of sage by-products in the lamb diets enhanced the antioxidant status of both blood and meat.

RESUMO

OBJECTIVE: Reduced performance in several cognitive domains has been repeatedly related to hepatitis C virus (HCV). Nevertheless, there is no consensus about the severity or cognitive profile. Moreover, other possible influential variables are scarcely controlled. The aim of this study is to define the specific cognitive profile in HCV after controlling for confounding variables. METHODS: Forty-two HCV patients were distributed in 2groups according to the presence of co-infection with human immunodeficiency virus; a third group with 22 healthy controls was also included. The neuropsychological assessment included tests that assess processing speed, executive functioning, verbal memory, visual memory and working memory. Measures of depression (BDI), anxiety (HAM-A), fatigue (MAF), anhedonia (PAS), insomnia (ISI), quality of life (SF-36) and history of drug abuse (DAST-20) were taken in order to explore differences among groups and to control for their possible influence on cognitive performance. RESULTS: HCV patients (including human immunodeficiency virus-coinfection) performed significantly worse in all cognitive measures. However, when the effect of BDI, HAM-A, MAF, ISI, SF-36 & DAST-20 was controlled, only verbal memory of HCV patients differed among groups. Coinfected patients performed worse in verbal memory. CONCLUSIONS: According to previous studies verbal memory is the unique cognitive domain related to the effect of HCV. The present study does not support that the neurovirulence effect of HCV is decreasing cognitive performance in HCV patients. Nevertheless, the present study cannot relate the fronto-striatal disruption with the cognitive performance in HCV patients.

RESUMO

The main goal of the present study was to describe the volatile profile of three different basil genotypes (Genovese and Green and Purple Iranian), and the impact that water stress (75% and 50% field capacity) and storage time (up to 7days) have under mild refrigerated conditions. The chromatographic profile pointed to three different chemotypes: linalool/eugenol, neral/geranial, and estragol, for Genovese, Green, and Purple genotypes, respectively. Water stress depleted the volatile profile of these three landraces, due to a reduction in the absolute concentrations of some of the components related to fresh aroma (linalool, nerol, geraniol and eugenol). The stability of the basil volatile profile during storage varied depending on the water stress that had been applied. Concentration reductions of close to 50% were quantified for most of the components identified in the Purple genotype.
