Forensic Drug Identification by Gas Chromatography- Infrared Spectroscopy . Award Number: 2008-DN-BX-K161 . Robert Shipman, Trisha Conti, PhD, Tara Tighe, MS and Eric Buel, PhD . ABSTRACT . The primary goal of the forensic drug examiner is the unequivocal identification of any controlled substance present in a drug exhibit. Most forensic laboratories routinely employ Gas Chromatography/ Mass Spectrometry (GC/MS) as the preferred method for this examination.
Vasodepressor syncope is a common medical problem that can usually be diagnosed through an accurate history and upright tilt testing. In most cases, long-term therapy is not necessary, and the majority of patients experience a striking decrease in syncopal episodes following a tilt test and the ensuing reassuring explanation from their physician.
Sympathetic innervation will cause vasoconstriction of vessels to GI organs and stuff you DON'T need during a sympathetic (fight or flight) response (in addition to increasing heart rate, etc.). Parasympathetic will cause vasodilation of these vessels, so lots of blood to GI organs during rest and digest.here be vasodilation, which has nothing to do with sympathetic stimulation, to muscle groups that you would be using during the flight or fight response. Those muscles are active and require oxygen and other metabolic needs at that time.
