BACKGROUND Cigarette butts are the most common form of litter, as an estimated 4.5 trillion cigarette butts are thrown away every year worldwide. Many chemical products are used during the course of growing tobacco and manufacturing cigarettes, the residues of which may be found in cigarettes prepared for consumption. Additionally, over 4000 chemicals may(More)
Carbatrol, a new dosage form of carbamazepine (CBZ), was developed consisting of three different types of pellets (immediate release, controlled release, and enteric release). The objective of this study was to explore the influence of food on absorption of CBZ. This was a randomized, open-label, single-dose crossover study conducted in 12 healthy(More)
In vitro studies have implicated butyrylcholinesterase (BChE, E.C.3.1.1.8) as the major enzyme for metabolizing cocaine in humans, but little is known about endogenous BChE activity in monkeys and other animals often used in preclinical studies of cocaine. We compared BChE activity in 18 rhesus and 11 squirrel monkeys, using the colorimetric method of(More)
Dihydroergotamine, a 5-hydroxytryptamine antagonist, is used for the treatment of vascular headaches. A high-performance liquid chromatography assay with fluorescence detection is described for the determination of dihydroergotamine in plasma. The assay was validated over the concentration range 0.1-10 ng/ml plasma and applied to the analysis of plasma(More)
In humans, the plasma enzyme butyrylcholinesterase, BChE (EC 3.1.1.8), mediates the in vivo plasma hydrolysis of cocaine to the pharmacologically inactive metabolite ecgonine methyl ester, EME. This enzyme has been purified from human plasma to investigate the potential as a treatment for cocaine intoxication. Cocaine (2.1 micrograms mL-1) was incubated in(More)
Cigarette butts and other tobacco product wastes (TPW) are the most common items picked up in urban and beach cleanups worldwide. TPW contains all the toxins, nicotine, and carcinogens found in tobacco products, along with the plastic nonbiodegradable filter attached to almost all cigarettes sold in the United States and in most countries worldwide.(More)
In humans, the plasma enzyme, butyrylcholinesterase (E.C. 3.1.1.8), metabolizes cocaine to the water-soluble, pharmacologically inactive compounds, ecgonine methylester and benzoic acid. Homogeneous enzyme was purified from human plasma and used to determine the enzyme kinetic parameters of Km and Vmax with cocaine as the substrate. The KM (11.9 microM)(More)
