Two deaths involving 3, 4-methylenedioxypyrovalerone (MDPV) are reported. MDPV is a synthetic cathinone stimulant found in "bath salts" with neurological and cardiovascular toxicity. Biological specimens were analyzed for MDPV by GC/MS and LC/MS. A White man was found dead with signs of nausea and vomiting after repeatedly abusing bath salts during a(More)
The pharmacokinetics of a co-trimoxazole preparation (Bactrim Forte) containing trimethoprim (TMP) 160 mg and sulphamethoxazole (SMZ) 800 mg were determined in six young adults (29.3 +/- 4.4 s.d. years) and six elderly people (78.6 +/- 6.6 s.d. years). Following oral administration of a single dose, the pharmacokinetic parameters of SMZ and its(More)
Left ventricular size following endurance, sprint, and strength training. Med. Sci. Sports Exercise, Vol. 14, No. 5, pp. 344-347, 1982. Left ventricular dimensions in adolescent boys were determined before and after three types of training regimens: endurance (END), N = 8, means = 16.8 yr; sprint (SPR), N = 8, means = 16.3 yr; strength (STR), N = 12, means(More)
A predominantly right ventricular variant of isolated noncompaction cardiomyopathy is a potentially lethal disease entity, which only recently has become recognized in the clinical and cardiac imaging literature. There are currently few established morphologic criteria for the diagnosis other than right ventricular dilation and presence of excessive(More)
Chlamydia trachomatis, the most common bacterial sexually transmitted disease agent worldwide, enters a viable, non-dividing and non-infectious state (historically termed persistence and more recently referred to as the chlamydial stress response) when exposed to penicillin G in culture. Notably, penicillin G-exposed chlamydiae can reenter the normal(More)
In most katydids, females listen to and locate a stationary, singing male for mating. Pair formation differs in phaneropterine katydids where pairs form duets and the male typically Þnds the female after hearing her acoustic reply to his song. We recorded the duetting behavior of two cryptic species of phaneropterines, Amblycorypha rotundifolia (Scudder)(More)
In brief: Echocardiographic studies permit direct, accurate measurements of the ventricular wall thickness and cavity diameter. The authors review several of these studies, which show that elite athletes' left ventricles are larger than those of sedentary persons. Left ventricular wall thickness is greater in athletes excelling in sports involving static(More)
The pharmacokinetics of Hydergine was studied following intramuscular administration in a group of 6 subjects aged 76-86 and following oral administration in 6 subjects aged 66-86. Comparison with a control group of healthy volunteers (average age of 25) showed: --a marked reduction (- 50%) in renal clearance (p less than 0.001), related to the decrease in(More)
To document the effects of endurance training upon left ventricular dimensions, an echocardiographic examination was performed on 11 young (19 +/- 1 years) and 13 middle-aged (40 +/- 3 years) subjects before and after a 20-week endurance training program. The maximal working capacity was increased by 28% and 27% in young and in middle-aged subjects,(More)
