Is a single nucleotide polymorphism in the alcohol dehydrogenase 7 gene ( alanine to glycine substitution at amino acid 92 ) associated with the risk of squamous cell carcinoma of the head and neck?
The current results support the ADH7 A92G SNP as a marker for the risk of SCCHN in non-Hispanic white populations.
Results indicate the stressor criterion as defined by the DSM may not be informative in characterizing PTSD symptoms and sequelae. In the context of ongoing DSM-5 revision, these results suggest that criterion A1 could be expanded in DSM-5 without much consequence for our understanding of PTSD phenomenology. Events not considered qualifying stressors under the DSM produced PTSD as consequential as PTSD following DSM-III events, suggesting PTSD may be an aberrantly severe but nonspecific stress response syndrome.
