BACKGROUND Little is known concerning the enantioselective disposition of 3,4-methylenedioxymethamphetamine (MDMA; ecstasy) in humans. In addition, the potential of utilizing the stereochemical composition of an analyte in biological media for forensic purposes requires investigation. METHODS The enantiomers of MDMA and its demethylated metabolite,(More)
UNLABELLED Chronic wounds are a major healthcare problem costing the United States billions of dollars a year. The American Academy of Dermatology has underscored the significance of wound care in dermatological practice. It is critical for all dermatologists to understand the elements of diagnosis and therapy. We emphasize major aspects of diagnosis and(More)
The aim of this investigation was to examine the effect of 3,4-methylenedioxymethamphetamine (MDMA) administration on arginine vasopressin (AVP) release. (R,S)-MDMA (40 mg) was administered to eight normally hydrated healthy male volunteers (22-32 years) and blood samples were collected up to 24 h. Plasma was assayed for AVP and cortisol by(More)
CONTEXT A method based on two GH-dependent markers, IGF-I and pro-collagen type III N-terminal peptide (P-III-P), has been devised to detect exogenously administered GH. Because previous studies on the detection of GH abuse involved predominantly adult athletes, the method must be validated in adolescent athletes. OBJECTIVE The aim of the study was to(More)
BACKGROUND Immune system activation is frequently reported in patients with Alzheimer's disease (AD). However, it remains unknown whether this is a cause, a consequence, or an epiphenomenon of brain degeneration. OBJECTIVE The present study examines whether immunological abnormalities occur in a well-established murine AD model and if so, how they relate(More)
The current drastic escalation in obesity may be contributing to the exponential rise in drugs used for image enhancement. Drugs such as anabolic-androgenic steroids (AAS) are perceived as a viable method of achieving a perfect physique. They are also the most widely abused drugs in sport. The Internet has encouraged the abuse of expensive drugs,(More)
OBJECTIVE IGF-I and IGF binding protein (IGFBP)-3 levels in man are positively regulated by GH status; in contrast, evidence suggests an inverse relationship between GH status and IGFBP-2. We investigated the effects of somatropin administration on the serum concentrations of these analytes, together with serum and urinary concentrations of GH, to evaluate(More)
tGolgin-1 (golgin-245, trans golgi p230) and golgin-97 are members of a family of peripheral membrane proteins of unknown function that localize to the trans Golgi network (TGN) through a conserved C-terminal GRIP domain. We have probed for GRIP protein function by assessing the consequences of overexpressing isolated GRIP domains. By semi-quantitative(More)
Blood lead and hypertension are associated in adults. We attempted to duplicate this finding in a presumably more susceptible group of children. Small but statistically significant negative corelations were found between blood pressure and lead levels in these children. This indicated to us that the proposed positive relationship did not exist, and that the(More)
