چکیده
We analyze properties of electromagnetic radiation in helical undulators with a particular emphasis on the orbital angular momentum of the radiated photons. We demonstrate that all harmonics higher than the first one radiated in a helical undulator carry an orbital angular momentum. We discuss some possible applications of this phenomenon and the ways of effective generation of these photons in a helical undulator. We call for review of results of experiments performed where the higher harmonics radiated in a helical undulator might be involved.

In vitro stability of free and glucuronidated cannabinoids in blood and plasma following controlled smoked cannabis.
BACKGROUND Blood and plasma cannabinoid stability is important for test interpretation and is best studied in authentic rather than fortified samples. METHODS Low and high blood and plasma pools were created for each of 10 participants after they smoked a cannabis cigarette. The stabilities of Δ(9)-tetrahydrocannabinol (THC), 11-hydroxy-THC (11-OH-THC), 11-nor-9-carboxy-THC (THCCOOH), cannabi...
متن کاملCannabinoid disposition in oral fluid after controlled smoked cannabis.
BACKGROUND We measured Δ(9)-tetrahydrocannabinol (THC), 11-nor-9-carboxy-THC (THCCOOH), cannabidiol (CBD), and cannabinol (CBN) disposition in oral fluid (OF) following controlled cannabis smoking to evaluate whether monitoring multiple cannabinoids in OF improved OF test interpretation. METHODS Cannabis smokers provided written informed consent for this institutional review board-approved st...
متن کاملCannabinoids in exhaled breath following controlled administration of smoked cannabis.
BACKGROUND Δ(9)-Tetrahydrocannabinol (THC), 11-nor-9-carboxy-THC (THCCOOH), and cannabinol (CBN) were measured in breath following controlled cannabis smoking to characterize the time course and windows of detection of breath cannabinoids. METHODS Exhaled breath was collected from chronic (≥4 times per week) and occasional (<twice per week) smokers before and after smoking a 6.8% THC cigarett...
متن کاملSimultaneous and sensitive analysis of THC, 11-OH-THC, THC-COOH, CBD, and CBN by GC-MS in plasma after oral application of small doses of THC and cannabis extract.
Besides the psychoactive Delta(9)-tetrahydrocannabinol (THC), hashish and marijuana as well as cannabis-based medicine extracts contain varying amounts of cannabidiol (CBD) and of the degradation product cannabinol (CBN). The additional determination of these compounds is interesting from forensic and medical points of view because it can be used for further proof of cannabis exposure and becau...
متن کاملQuantitative analysis of contraction band and coagulation necrosis after ischemia and reperfusion in the porcine heart.
To assess the importance of contraction band necrosis (CBN) in reperfusion, CBN, coagulation necrosis (CN), and infarct size, expressed as CBN + CN, were quantitatively analyzed in 25 porcine hearts without collateral circulation. The left anterior descending coronary artery was ligated for 20, 30, 60, and 120 min and then reperfused for 8 hr (groups 1 to 4, respectively). Five hearts were not ...
متن کاملIdentification of recent cannabis use: whole-blood and plasma free and glucuronidated cannabinoid pharmacokinetics following controlled smoked cannabis administration.
BACKGROUND Δ⁹-Tetrahydrocannabinol (THC) is the most frequently observed illicit drug in investigations of accidents and driving under the influence of drugs. THC-glucuronide has been suggested as a marker of recent cannabis use, but there are no blood data following controlled THC administration to test this hypothesis. Furthermore, there are no studies directly examining whole-blood cannabino...
