Lifestyle recommendations for the prevention and management of metabolic syndrome: an international panel recommendation.
2017
The importance of metabolic syndrome (MetS) lies in its associated risk of cardiovascular disease and type 2 diabetes, as well as other harmful conditions such as nonalcoholic fatty liver disease. In this report, the available scientific evidence on the associations between lifestyle changes and MetS and its components is reviewed to derive recommendations for MetS prevention and management. Weight loss through an energy-restricted diet together with increased energy expenditure through physical activity contribute to the prevention and treatment of MetS. A Mediterranean-type diet, with or without energy restriction, is an effective treatment component. This dietary pattern should be built …
Vicarious Social Defeat Increases Conditioned Rewarding Effects of Cocaine and Ethanol Intake in Female Mice
2023
Stress is a critical factor in the development of mood and drug use disorders. The social defeat model is not appropriate for female rodents due to their low level of aggression. Therefore, a robust female model of social stress needs to be developed and validated. The aim of the present study was to unravel the long-lasting effects of vicarious social defeat (VSD) on the conditioned rewarding effects of cocaine and ethanol intake in female mice. Although VSD seems to be a good model for inducing behavioral and physiologic endophenotypes induced by stress, there are no studies to date that characterize the effect of VSD on cocaine or alcohol use. The results confirm that VSD females showed …
P-76D-PENICILLAMINE, AN ACETALDEHYDE SEQUESTERING AGENT, REDUCES ETHANOL PREFERENCE IN ALCOHOL-NAÏVE RATS
2015
In previous investigations, we demonstrated that D-penicillamine (DP), a sulfhydryl aminoacid which has been studied as sequestration agent of acetaldehyde (ACD), is able to prevent the alcohol deprivation effect (ADE) but not voluntary ethanol consumption. Both results were obtained in long-term ethanol-experienced Wistar rats. Based on a previous …
Alcohol boosts pheromone production in male flies and makes them sexier
2020
The attraction of Drosophila melanogaster towards byproducts of alcoholic fermentation, especially ethanol, has been extensively studied 1–4. However, the adaptive value of this behavior has not been elucidated. Previous studies have suggested anthropomorphic interpretations of D. melanogaster behavior towards alcohols 5,6. Here, we instead assert that there exists a simple yet vital biological rationale for alcohol contact and consumption by these insects. We show that exposure to alcohols, especially methanol, results in an immediate amplification of fatty acid ester pheromone levels, which in turn elevates the probability that a male will successfully compete for a female during courtshi…
Influence of indigenous Hanseniaspora uvarum and Saccharomyces cerevisiae from sugar-rich substrates on the aromatic composition of loquat beer
2022
The demand for unique and exclusive food products and beverages is constantly on the increase. One of the products that mostly evolved to encounter market dynamics in the last decade is craft beer. For a long time, craft breweries have included fruit in beer production to enrich flavour and aroma profile of different beer styles. In this study, for the first time, the use of Saccharomyces and non-Saccharomyces yeast strains isolated from high -sugar matrices (manna and fermented honey by-products) were investigated to diversify fruit craft beer pro-duction, in order to improve the fermentation process and highlight the complexity of aroma profiles generated during alcoholic fermentation. Tw…
Sucrose medium osmolality as a regulator of anabolic and catabolic parameters inZymomonas culture
1996
This study focuses on the growth of Zymomonas mobilis strain 113 S and its ethanol and levan production under the conditions of increasing sucrose medium osmolality caused by NaCl, KCl, sorbitol or maltose. The increase in medium osmolality (700-1,500 mosml/kg) was accompanied by the inhibition of growth (growth rate, biomass yield) and ethanol production (specific productivity and yield). In contrast, levan synthesis was less affected or even stimulated and, as a consequence, levan specific productivity was increased significantly. A decrease in the anabolic growth parameters correlated with a parallel inhibition of glucose-6-P dehydrogenase and alcohol dehydrogenase (isoenzyme ADH II) act…
P-78D-PENICILLAMINE PREVENTS THE ALCOHOL DEPRIVATION EFFECT IN THE OPERANT SELF-AMINISTRATION PARADIGM
2015
Although pharmacological treatments for relapse prevention have experienced some progress, their general effectiveness can be considered low and the problem could not be considered solved. In recent years, our group has explored the use of acetaldehyde (ACD) sequestering agents as a new and very promising strategy. These agents, such as …
An Animal Model of Alcohol Binge Drinking: Chronic-Intermittent Ethanol Administration in Rodents
2019
Binge drinking (BD), characterized by intermittent consumption of large quantities of alcohol in short periods of time, is the main alcohol consumption pattern in adolescents and young adults. BD has serious biomedical consequences, and it is a prominent risk factor for later development of alcohol use disorders. Rodent models offer exceptional power to study these negative consequences of BD. This chapter focuses on one of these BD models: the chronic-intermittent ethanol administration (CIEA) paradigm. Essentially, CIEA consists of the administration in rats or mice of i.p. injections of ethanol (doses: 3-4 g/kg) for several consecutive days each week, in alternation with several days wit…
Kontinuierlicher exspiratorischer Alkoholnachweis
1995
The absorption of large volumes of irrigation fluid is a major problem in transurethral prostatic surgery (TUR-P). Various indicators have been tested to monitor fluid absorption with regard to continuous registration and sufficient accuracy. The volumetric fluid balance is not suitable as a routine method because of its inaccuracy. Easily accessible parameters are unspecific because of surgical bleeding (haematocrit [Hct]), or are interfered with by physiological counter-regulatory actions (serum sodium [Na] concentration). In 1986 Hulten et al. suggested adding 2% ethanol to the irrigation fluid as a marker and investigated it intermittently in the expired air with an alcohol-test applian…
Acetaldehyde effects in the brain
2015
The effects of alcohol have been widely studied during the past century as alcohol abuse is a major health problem in Western society. In the last years, a growing body of evidence indicates that acetaldehyde, the first oxidation product of ethanol, is one of the mediators of peripheral and central effects of ethanol. Indeed, acetaldehyde has been recently taken into account as the mediator of the rewarding properties of alcohol. The role of acetaldehyde in ethanol-related properties has been proved by enzymatic manipulation studies in which the inactivation of acetaldehyde potentially synthesized in the brain produces the same results as blocking the formation of acetaldehyde by inhibiting…
