BACKGROUND: A number of social drinkers claim that they do not experience next-day hangovers despite consuming large quantities of alcohol. The aim of this study was to investigate the characteristics of drinkers who claim to be hangover immune and compare them with drinkers who do report having hangovers. METHODS: A total of 36 social drinkers participated in a naturalistic study consisting of a hangover day (alcohol consumed) and a control day (no alcohol consumed)...

Hangover refers to the cluster of physiological and behavioral symptoms that occur following the end of a drinking episode. While hangover has been studied after the typical oral consumption of alcohol, the occurrence of hangover following intravenous (IV) alcohol administration in human laboratory studies has not been previously reported. This study characterizes hangover symptoms and post-infusion drinking behavior following acute IV alcohol administration in social drinkers. Twenty-one to thirty-year-old healthy social drinkers (n = 24) underwent an alcohol clamp session at breath alcohol concentration of 0...

In cytoplasmic inheritance, structural states of a parent cell could be transmitted to offspring cells via two mechanisms. The first is referred to as the hangover of parent structure, where the structure itself remains and faithfully transmits within offspring cells; the second is structural inheritance, wherein the parent structure functions as a template for development of new offspring structure. We estimated to what extent the parent structure affects the development of offspring structure by structural inheritance, using a clone of the diatom Cyclotella meneghiniana The cell has two siliceous valves (a cell wall part at both cell poles): one is inherited from the parent and the other is newly formed...

The effects of high-dose ethanol intoxication on cognitive flexibility processes are not well understood, and processes related to hangover after intoxication have remained even more elusive. Similarly, it is unknown in how far the complexity of cognitive flexibility processes is affected by intoxication and hangover effects. We performed a neurophysiological study applying high density electroencephalography (EEG) recording to analyze event-related potentials (ERPs) and perform source localization in a task switching paradigm which varied the complexity of task switching by means of memory demands...

BACKGROUND: The aim of this study was to examine the relationship between urine ethanol concentration and alcohol hangover severity. METHODS: N = 36 healthy social drinkers participated in a naturalistic study, comprising a hangover day and a control day. N = 18 of them have regular hangovers (the hangover group), while the other N = 18 claim to be hangover immune (hangover-immune group). On each test day at 9.30 am, urine samples were collected. Participants rated their overall hangover severity on a scale from 0 (absent) to 10 (extreme), as well as 18 individual hangover symptoms...

RATIONALE: Alcoholism is a complex disorder in which diverse pathophysiological processes contribute to initiation and progression, resulting in a high degree of heterogeneity among patients. Few pharmacotherapies are presently available, and patient responses to these are variable. The nociceptin/orphanin FQ (NOP) receptor has been suggested to play a role both in alcohol reward and in negatively reinforced alcohol seeking. Previous studies have shown that NOP-receptor activation reduces alcohol intake in genetically selected alcohol-preferring as well as alcohol-dependent rats...

In this study, heat-treated cucumber juice was assessed for its protective effect on blood alcohol levels and hepatic alcohol metabolic enzyme system in experimental rats. Initially, during detoxification of alcohol, all groups were orally dosed to 22% alcohol (6ml/kg body weight) along with different concentrations of heat-treated cucumber juice (10, 100 and 500mg/kg) and commercial goods for hangover-removal on sale (2ml/kg). Cucumber juice was dosed before 30 min, and simultaneously after 30min of alcohol administration, and its hepatoprotective effect on blood alcohol levels and hepatic alcohol metabolic enzyme system in experimental rats was evaluated...

BACKGROUND: The Alcohol Use Disorder and Associated Disabilities Interview Schedule-IV (AUDADIS-IV) and AUDADIS-5 are diagnostic interviews used in major epidemiological and other studies of alcohol use disorder (AUD). Much of what we know regarding the prevalence of AUD in the United States is based upon this interview. However, past research and meta-analytic evidence suggest that differential operationalization of the AUD criteria across instruments can lead to differential endorsement of symptoms and resulting AUD diagnosis rates...

Effects of binge drinking on cognitive control and response selection are increasingly recognized in research on alcohol (ethanol) effects. Yet, little is known about how those processes are modulated by hangover effects. Given that acute intoxication and hangover seem to be characterized by partly divergent effects and mechanisms, further research on this topic is needed. In the current study, we hence investigated this with a special focus on potentially differential effects of alcohol intoxication and subsequent hangover on sub-processes involved in the decision to select a response...

Capsosiphon fulvescens is a filamentous green algae in the class Ulvophyceae. It has been consumed as food with unique flavor and soft texture to treat stomach disorders and hangovers, and its economic value justifies studying its nutritional and potential therapeutic effects. In contrast to these applications, only a few taxonomic studies have been conducted on C. fulvescens. In particular, classification and phylogenetic relationships of the C. fulvescens below the order level are controversial. To determine its phylogenetic position in the class, we used rbcL and 18S rDNA sequences as molecular markers to construct phylogenetic trees...

The effect of alcohol hangover on cognitive processing has received little attention. We explored the effect of alcohol hangover on choice response time (RT), a dominant dependent variable (DV) in cognitive research. Prior research of the effect of hangover on RT has produced mixed findings; all studies reviewed relied exclusively on estimates of central tendency (e.g. mean RT), which has limited information value. Here we present novel analytical methods by going beyond mean RT analysis. Specifically, we examined performance in hangover conditions (n=31) across the whole RT distribution by fitting ex-Gaussian models to participant data, providing a formal description of the RT distribution...

AIMS: While inhibition has been studied extensively in correlation to alcohol abuse within the adult population, it has been studied less so in relation to the alcohol consumption habits of young adults. Accordingly, this is the first study with the objective of identifying which subcomponent(s) of inhibitory performance, behaviourally measured by the withholding of a pre-potent response, the cancellation of a pre-potent response and interference inhibition will best predict binge drinking habits among young adults...

The consumption of alcohol is often accompanied by other foods, such as fruits and vegetables. This study is aimed to investigate the effects of 20 selected fruits on ethanol metabolism to find out their potential health benefits and harmful impacts. The effects of the fruits on ethanol metabolism were characterized by the concentrations of ethanol and acetaldehyde in blood, as well as activities of alcohol dehydrogenase and acetaldehyde dehydrogenase in liver of mice. Furthermore, potential health benefits and harmful impacts of the fruits were evaluated by biochemical parameters including aspartate transaminase (AST), alanine transferase (ALT), malondialdehyde, and superoxide dismutase...

BACKGROUND: Alcohol-related blackouts are periods of amnesia that reflect the failure of the brain to record memories of what transpires while drinking. This paper examined the incidence, predictors, and behavioral correlates of blackouts among emerging adults and examined whether questions about blackouts could serve as better markers of risk for other alcohol related harms than questions about levels of consumption. METHODS: In 2012 to 2013, 1,463 (68%) of 2,140 respondents 1-year past high school reported having consumed alcohol...

The pharmacological management of insomnia has lately become a challenge for researchers worldwide. As per the third International Classification of Sleep disorders (ICSD-3) insomnia can be defined as a state with repeated difficulty in sleep initiation, duration, consolidation, or quality that occurs despite adequate opportunity and circumstances for sleep, and results in some form of daytime impairment. The conventional treatments approved for management of insomnia were benzodiazepines (BZDs) (estazolam, quazepam, triazolam, flurazepam and temazepam) and non-BZDs, also known as z-drugs (zaleplon, zolpidem, and eszopiclone), tricyclic antidepressant (TCA) doxepin as well as melatonin agonists, e...

Plant NAD(+)-dependent aminoaldehyde dehydrogenases (AMADHs, EC belong to the family 10 of aldehyde dehydrogenases. They participate in the metabolism of polyamines or osmoprotectants. The enzymes are characterized by their broad substrate specificity covering ω-aminoaldehydes, aliphatic and aromatic aldehydes as well as nitrogen-containing heterocyclic aldehydes. The isoenzyme 1 from tomato (Solanum lycopersicum; SlAMADH1) oxidizes aliphatic aldehydes very efficiently and converts also furfural, its derivatives or benzaldehyde, which are present at low concentrations in alcoholic distillates such as fruit brandy...
