Cannabinoids are a group of 21 carbon terpenophenolic compounds produced uniquely by Cannabis sativa and Cannabis indica species.[1,2] These plant-derived compounds may be referred to as phytocannabinoids. Although delta-9-tetrahydrocannabinol (THC) is the primary psychoactive ingredient, other known compounds with biologic activity are cannabinol, cannabidiol, cannabichromene, cannabigerol, te...

This randomised, double-blind, placebo-controlled, cross-over study was designed to identify which pharmacodynamic parameters most accurately quantify the effects of delta-9-Tetrahydrocannabinol (THC), the predominantly psychoactive component of cannabis. In addition, we investigated the acceptability and usefulness of a novel mode of intrapulmonary THC administration using a Volcano vaporizer ...

We give a ncw method for direct reconstruction of threc-dimcnsional objects from a fcw electron micrographs taken at angles which nced not exceed a range of 60 degrees. Thc method works for totally asymmctric objects, and rcquircs littlc computer timc or storage. It is also applicable to X-ray photography. and may greatly reduce the exposurc compared to current methods of body-scction radiography.

Recent phenomenological-theoretical studies' 4 have discussed var1ous poss1ble modes of coexistence of superconducting and magnetic order in those ternary compounds which exhibit re-entry from the superconducting state to a normal-resistive (but ferromagnetic) state.

then, under mild restrictions on Q, thc resulting feedback system is a "good" system by most classical criteria. An equally significant result is as follows [2 I. Given a feedback control law u = -k'x for the system (I), which is known to yield an asymptotically stable closed-loop system, then a ncccssary and sufficient condition for this control law to bc optimal with respcct to a performance ...

BACKGROUND Oral fluid (OF) testing is increasingly important for drug treatment, workplace, and drugged-driving programs. There is interest in predicting plasma or whole-blood concentrations from OF concentrations; however, the relationship between these matrices is incompletely characterized because of few controlled drug-administration studies. METHODS Ten male daily cannabis smokers receiv...

Knowledge of results (KR)--information feedback about goal achievement--has been one of the most extensively examined variables in motor learning. In most natural movement learning situations, however, instructors more common]y provide augmented information regarding various kinematic or kinetic aspects of the movement pattern itself (sometimes termed knowledge of performance, KP). But despite ...
