Glucosides of 1,4-benzoxazine derivatives have been isolated from corn, rye, wheat and Coix Lachryma Jobi seedlings by gel filtration. 2-(2,4-Dihydroxy-7-methoxy-1,4(2H)-benzoxazin-3(4H)-on)-β-β-d-glucopyranoside (DIMBOA-Glc.) 2-(2-hydroxy-7-methoxy-1,4(2H)-benzoxazin-3(4H)-on)-β-d-glucopyranoside (HMBOA-Glc.) were demonstrated in all four plants, with 2-(2,4-dihydroxy-1,4(2H)-benzoxazin-3(4H)-on)-β-d-glucopyranoside (DIBOA-Glc.) corn...
In this work we aimed to study the possibility of using supervised classifiers quantify main components carotid atherosclerotic plaque in vivo on basis multisequence MRI data. data consisting five MR weightings were obtained from 25 symptomatic subjects. Histological micrographs endarterectomy specimens carotids used as a standard reference for training and evaluation. The set subjects was divided (12 subjects) an evaluation (13 subjects). Four different two human readers determined...
An exact scheme is presented to determine the effective viscosity tensor for periodic arrays of hard spherical particles suspended in a Newtonian fluid. In highly symmetric case cubic lattices this characterized by only two parameters. These parameters are calculated numerically three lattice types and whole range volume fractions. The correctness present method its numerical implementation confirmed comparison with analytical results known from literature. Some regular terms determined that...
Abstract Herein, we present the formation of transient radical ion pairs (RIPs) by single‐electron transfer (SET) in phosphine−quinone systems and explore their potential for activation C−H bonds. PMes 3 (Mes=2,4,6‐Me C 6 H 2 ) reacts with DDQ (2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone) P−O bonded zwitterionic adduct Mes P−DDQ ( 1 ), while reaction sterically more crowded PTip (Tip=2,4,6‐ i Pr afforded bond product Tip P(H)(2‐[CMe (DDQ)]‐4,6‐ ‐C ). UV/Vis EPR spectroscopic studies showed...
In the seeds ofAllium altaicun (Pall.)Reyse a set of enzymes was found, metabolizing choline esters, composed active esterases and acetyltransferase. Choline esterase cleaving acetylcholine occurs in five isoenzymes. The enzyme preparation hydrolyses strongly acetylthiocholine sinapine, but weakly butyrylthiocholine (20%) comparison with acetylthiocholine. hydrolysis substrates mentioned is inhibited by physostigmine neostigmine, it not specific inhibitor (BW 284 C51). addition to hydrolytic...
Abstract We present the design and comprehensive investigation of stable para ‐substituted triarylamine–2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone (DDQ) radical ion pairs (RIPs) generated via single‐electron transfer (SET). quantified degree SET in both solution solid phases, utilising a suite spectroscopic techniques including IR, EPR, NMR, single‐crystal X‐ray diffraction (SC–XRD). Our findings reveal that extent is significantly influenced by nature substituents (MeO > t Bu Br) polarity...
It is known that the electromagnetic field caused by a moving charge depends on its acceleration. Therefore, if bunch of charged particles has circular trajectory, self fields in depend radius curvature. We will treat these analytically for one-dimensional bunch, using Lienard-Wiechert potentials. These retarded positions charges bunch. show one only to determine explicitely endpoints The model predicts non-zero tangential and radial forces middle which angular width velocity. Expressions...
