BACKGROUND Malaria and alcohol consumption both represent major public health problems. Alcohol consumption is rising in developing countries and, as efforts to manage malaria are expanded, understanding the links between malaria and alcohol consumption becomes crucial. Our aim was to ascertain the effect of beer consumption on human attractiveness to malaria mosquitoes in semi field conditions...

Flavor quality is of major importance to the consumer, but the flavor characteristics of beer appear to deteriorate greatly with time, at a rate depending on the composition of the beer and its storage conditions (notably pH). Prior to identifying the influence of pH on the development of the most intense staling flavors found in aged lager beers, the corresponding key flavor compounds were det...

Current pharmacotherapies for alcohol dependence in humans (e.g., naltrexone, acamprosate) are meeting with only limited therapeutic success. The development of novel pharmacotherapies is urgently needed but is reliant upon the screening of large numbers of candidate "anticraving" drugs using appropriate animal models. The development of animal models is complex because (1) laboratory animals a...

During beer fermentation, the brewer's yeast Saccharomyces cerevisiae experiences a variety of shifting growth conditions, culminating in a low-oxygen, low-nutrient, high-ethanol, acidic environment. In beers that are bottle conditioned (i.e., carbonated in the bottle by supplying yeast with a small amount of sugar to metabolize into CO2), the S. cerevisiae cells must overcome these stressors t...

Fluorometry, ion-exchange chromatography, electrophoretic separations and Fourier transform±infrared (FT±IR) spectra were used to determine and characterize amino acids and proteins in 15 di€erent beer samples. Proteins precipitated by ammonium sulfate yielded complex electrophoretic patterns. The major bands corresponded to 45±40 kDa as determined by a two-dimensional gel electrophoresis (2-DE...

Process hygiene plays a major role in the production of high quality beer. Knowledge of microorganisms found in the brewery environment and the control of microbial fouling are both essential in the prevention of microbial spoilage of beer. The present study examined the growth of surface-attached beer spoilage organisms and the detection and elimination of microbial biofilms. Moreover, the det...

Extinction promotes abstinence from drug seeking. Extinction expression is an active process, dependent on infralimbic prefrontal cortex (ilPFC). However, the neurocircuitry mediating extinction expression is unknown. Here we studied the neural mechanisms for expression of extinction of alcoholic beer seeking in rats. We first examined the pattern of activation in prefrontal cortex projections ...

The spoilage of beer by bacteria is of great concern to the brewer as this can lead to turbidity and abnormal flavors. The polymerase chain reaction (PCR) method for detection of beer-spoilage bacteria is highly specific and provides results much faster than traditional microbiology techniques. However, one of the drawbacks is the inability to differentiate between live and dead cells. In this ...
