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.
The common reason behind each syncopal or fainting episode is a temporary lack of oxygen-rich (red) blood getting to the brain. However, many different problems can cause a decrease in blood flow to the brain. Some types of syncope include: Vasovagal syncope. This is the most common type of syncope.
