Aim:
This study aimed to demonstrate that opportunistic health screening at health expos can provide an overall impression of alcohol consumption patterns.
Design:
A repeated cross-sectional survey design, completed over a four-year period (2011-2014), was used to assess the risk of harmful alcohol consumption, within a community setting of older adults, in the South West region of Western Australia.
Methods:
An alcohol screening survey (AUDIT) was used to collect data on alcohol consumption patterns on those aged 65 years and over. A total of 411 surveys were completed.
Results:
There was a statistically significant difference in mean risk scores across the four years (p < .001). 6.3-22.2% of survey completers presented as 'risky', and a further 3.8-12.3% as 'high risk' in terms of alcohol consumption.
Conclusions:
Opportunistic screening for alcohol consumption during health expos can aid the identification of at-risk individuals who may require further education or treatment.

Western Blotting
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.

Oxidation of Alcohols
The process of oxidation in a chemical reaction is observed in any of the three forms:
Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.
