Differential Effects of Alcohol on Memory Performance in Adolescent Men and Women with a Binge Drinking History.
2017
Aims Binge drinking (BD) is characterized by intermittent consumption of large quantities of alcohol in short periods. This pattern of drinking is prevalent among adolescents, and has been associated with undermined learning and memory ability. This study investigates the relationships between a history of BD and the effects of acute exposure to alcohol on learning and memory performance in adolescent men and women. Methods A high, acute dose of alcohol or control refreshment was administered to a sample of 172 adolescent undergraduate students, some of which had a history of BD and others of which had refrained from alcohol consumption. Subsequently, immediate visual memory (IVM) and worki…
Fermentative stress adaptation of hybrids within the Saccharomyces sensu stricto complex.
2008
Along the fermentation process yeasts are affected by a succession of stress conditions that affect their viability and fermentation efficiency. Among the stress conditions the most relevant are high sugar concentration and low pH in musts, temperature and, as fermentation progresses, ethanol accumulation. Nowadays, due to the demanding nature of modern winemaking practices and sophisticated wine markets, there is an ever-growing search for particular wine yeast strains possessing a wide range of optimized, improved or novel enological characteristics. Traditionally, the species S. cerevisiae and S. bayanus within the Saccharomyces sensu stricto species are considered some of the most impor…
