Aim: The nonlinear elimination rate of THC and metabolites in blood complicates the interpretation of last cannabis use, which is an important information in DUID cases. We evaluated cannabinoids in blood and hydrolysed urine from 50 DUID cases in order to gain additional information about last cannabis use. Methods: THC, THC-OH and THC-COOH were analysed in blood and hydrolysed urine (βglucuro...

Open Access Currently, endoscopic ultrasonography (EUS) is the best available tool for evaluation of a subepithelial lesion (SEL). However, imaging study alone with EUS does not always provide an accurate diagnosis. 1 If the information provided by EUS on the echogenicity and originating layer of SEL is not typical for an " educated guess, " patients may become anxious because of the uncertaint...

Dear Dr. Bedrossian: Here in, we report our study regarding the value of additional or minimal number of ThinPrep slides per case needed to establish a correct diagnosis on cytology specimens. The objective of this study is to explore whether preparing a second ThinPrep (TP) slide that presumably contains additional clusters would improve the diagnostic accuracy of fine needle aspiration (FNA)?...

In this paper‎, ‎we give the notions of crossed polymodule and cat$^1$-polygroup‎ ‎as a generalization of Loday's definition‎. ‎Then‎, ‎we define the pullback cat$^1$-polygroup and we obtain some results in this respect‎. ‎Specially‎, ‎we prove that by a pullback cat$^1$-polygroup we can obtain a cat$^1$-group‎.

An origin-based solution algorithm, named OBTAIN (origin-based traffic assignment for infrastructure networks), was recently developed for solving the traffic assignment problems (Bar-Gera and Boyce, 2003). This algorithm defines the solution variables in an intermediate way between links and routes, and has been proven to be superior to the link-based Frank-Wolfe method in both computational t...

in this paper, we study fuzzy substructures in connection withhv-structures. the original idea comes from geometry, especially from thetwo dimensional euclidean vector space. using parameters, we obtain a largenumber of hyperstructures of the group-like or ring-like types. we connect,also, the mentioned hyperstructures with the theta-operations to obtain morestrict hyperstructures, as hv-groups...
