The lysozyme of hen's egg white is used in winemaking to control spontaneous lactic acid bacteria (LAB). A total of eight LAB strains, isolated from grape must and wine, were used to assess the inhibitory effects of wine phenolics on lysozyme activity. The presence of phenolics, extracted from grape pomace, in growth medium reduced the mortality rate due to(More)
AIMS To investigate the interactions between Botrytis cinerea and other moulds during grape withering and postharvest infection to obtain noble-rotten grapes. METHODS AND RESULTS Strains of Botrytis cinerea, Penicillium expansum, Penicillium crustosum, Aspergillus niger, Fusarium verticilloides and Alternaria alternata, isolated from naturally withered(More)
AIMS To explain the role of Saccharomyces cerevisiae and Saccharomyces uvarum strains (formerly Saccharomyces bayanus var. uvarum) in wine fermentation. METHODS AND RESULTS Indigenous Saccharomyces spp. yeasts were isolated from Amarone wine (Italy) and analysed. Genotypes were correlated to phenotypes: Melibiose(-) and Melibiose(+) strains displayed a(More)
The comparison of various adiposity indices in children and adolescents shows that there is a great similarity between the indices, and also between their ability to distinguish extreme groups. The adiposity indices used are highly correlated with weight and subscapular skinfold thickness, and are not generally independent of height. Differences in these(More)
The authors sought to assess the role of arbitration by a third reader of discordant double readings to reduce the rate of recalls to diagnostic assessment. A consecutive series of 7,660 double readings of screening examinations were considered. Discordant recalls were arbitrated by an expert reader (negative/positive). Diagnostic assessment was performed(More)
In hypertensive cardiac hypertrophy, the elevated coronary perfusion pressure compensates importantly for the raised coronary resistance. An imbalance between perfusion and left ventricular (LV) mass, such as that occurring with rapid or excessive blood pressure lowering, may result in an inadequate oxygen supply. In 28 primary hypertensives (Group A) with(More)
AIMS The study of the fermentation performance of Saccharomyces cerevisiae strains under high sugar stress during the vinification of partially dried grapes. METHODS AND RESULTS Microvinification of partially dried grape must with sugar concentration of 35 degrees Brix was performed using four commercial strains to carry out alcoholic fermentation. A(More)
Osteoporosis is characterized by bone mineral density (BMD) decreasing and spongy bone rearrangement with consequent loss of elasticity and increased bone fragility. Quantitative computed tomography (QCT) quantifies bone mineral content but does not describe spongy architecture. Analysis of trabecular pattern may provide additional information to evaluate(More)
This study was undertaken to test whether the emphasized systemic vasomotion during sympathetic activation in hypertension is shared by the pulmonary circulation. To this end, 10 normotensive and 29 primary hypertensive subjects were investigated during adrenergic stimulation by mental arithmetic and cold pressor test. Both stimuli induced a systemic(More)
