Aim: Acute ingestion of alcohol is often accompanied by cardiovascular dysregulation, malaise and even syncope. The full hemodynamic and cutaneous responses to the combination of alcohol and sugar (i.e., alcopops), a common combination in young people, and the mechanisms for the propensity to orthostatic intolerance are not well established. Thus, the purpose of this study was to evaluate the c...

Sir, We read with interest the review article in Brain by Siclari et al. (2010). Although the authors cite some relevant studies, in our opinion, they do not adequately discuss the possible causal link between alcohol ingestion and disorders of arousal. Siclari and colleagues state ‘criteria for establishing the putative role of an underlying sleep disorder in a specific violent act have been p...

Background: Tincture of opium (TOP) is currently used for maintenance therapy in treatment of opioids addiction. It contains ethanol. The present study was conducted to assess the increase in blood alcohol concentration (BAC) in its users; a process which may interfere with breath-alcohol test performed by law enforcement or traffic police. Methods: A total of 143 individuals were selected rand...

Ingesting alcohol and energy drinks together is associated with a decreased awareness of the physical and mental impairment caused by the alcohol without reducing the actual impairment. This is of particular concern for youth who have a baseline of less mature judgment. Adding energy drinks to alcohol tends to increase the rate of absorption through its carbonation and dilution of the alcohol, ...

Why only a subpopulation (about 15%) of humans develops liver cirrhosis due to alcohol is a critical as yet unanswered question. Liver-specific depletion of augmenter of liver regeneration (ALR) protein in mice causes robust steatosis and hepatocyte apoptosis by 2 weeks; these pathologies regress subsequently with return of ALR expression even at lower than control levels, but the mice develop ...

The effect of a moderate oral dose of ethanol/(0.5 g.kg-1 body weight) on nocturnal arterial oxygen saturation (SaO2) was evaluated in nine male patients with advanced chronic obstructive pulmonary disease (COPD), (median forced expiratory volume in one second (FEV1) 0.9 l, arterial oxygen tension (PaO2) 9.3 kPa, arterial carbon dioxide tension (PaCO2) 5.3 kPa). During the four study nights (tw...

The effect ethanol exerts on the human brain has not yet been addressed by longitudinal magnetic resonance (MR) spectroscopic experiments. Therefore, we longitudinally characterized cerebral metabolite changes in 15 healthy individuals by proton magnetic resonance spectroscopy ((1)H-MRS) subsequent to the ingestion of a standard beverage (mean peak blood alcohol concentration (BAC): 51.43 +/- 1...

Two lines of rats bred to differ in their voluntary alcohol consumption--the alcohol-abstaining UChA rats and the alcohol-drinking UChB rats--differ in how effectively toxic acetaldehyde is removed during alcohol metabolism. UChB animals carry efficient variants of the aldehyde dehydrogenase 2 (ALDH2) genes and have active mitochondria, resulting in fast removal of acetaldehyde. UChA animals, i...
