Excessive alcohol use is extremely prevalent in the United States, particularly among trauma‐exposed individuals. While several studies have examined genetic influences on alcohol use and related problems, this has not been studied in the context of trauma‐exposed populations. We report results from a genome‐wide association study of alcohol consumption and associated problems as measured by the alcohol...
A method for the extraction and analysis of ink samples was developed using microscopy with direct analyte probe nanoextraction coupled to nanospray ionization mass spectrometry (DAPNe-NSI-MS) for localized chemical analysis of document inks. Nanomanipulation can be effectively coupled to nanospray ionization mass spectrometry providing picomolar sensitivity, and the capability to analyze ultra-trace...
