The effects of 0.15% quasi steady-state end-tidal isoflurane on the contrast sensitivity of five healthy volunteers were investigated by measuring their performance in computer generated letter discrimination tasks. A series of letters were displayed on a computer screen so that the luminance of...
SUMMARYWe have studied the effects of isoflurane or propofol anaesthesia on hepatic giutathione-S-transferase (GST) concentrations in 20 patients during and after prolonged plastic and reconstructive surgery (approximately 10 h). Mean plasma concentrations of GST did not exceed the normal range ...
Laboratory mice are commonly killed via exposure to gradually increasing concentrations of isoflurane and carbon dioxide (CO2) gas. Once rendered insensible using isoflurane or CO2, a high concentration of CO2 is used to decrease time to death. When the switch from isoflurane to a high flow rate...
BackgroundThe arterial pharmacokinetics of ketamine and norketamine enantiomers after racemic ketamine or S-ketamine i.v. administration were evaluated in seven gelding ponies in a crossover study (2-month interval).
Induction of anesthesia by inhalation of isoflurane is a frequently used procedure in models of immunological diseases. Here we investigated effects of a brief exposure to isoflurane on cytokine production by endotoxemic rats. Anesthesia was either performed by pentobarbital/fentanyl without or ...
ObjectivesTo evaluate cardiopulmonary effects and anaesthesia recovery quality in horses anaesthetized with isoflurane receiving medetomidine or S‐ketamine infusions.
ZusammenfassungDie Pyrolyse des Acetats von (+) (1R:4R:6S)-Caran-trans-4-ol (I) führt bei 10 Torr und Temperaturen zwischen 386 und 604° unter Abspaltung von Essigsäure zu einem Kohlenwasserstoff-Gemisch aus (+) (1R:6S)-Δ4-Caren (III), (+) (1R:6S)-Δ3-Caren (IV) und (+) (1R:4R)-trans-Δ2,80p-...
d-(+)-Limonene can be converted into the corresponding bicyclic organoborinate intermediate, B-methoxy-4,8-dimethyl-2-borabicyclo[3.3.1]nonane, by cyclic hydroboration with borane in THF, followed by methanolysis, and distillation of the product. Alternatively, cyclic hydroboration of d-(+)-limo...
Ganoine is a different enamel from “true” enamel. The crystallites end in the middle of the projection of epidermal cell onto the ganoine surface. In contrast, “true” enamel shows the borders of the hexagonal epidermal cells. Cosmine is a combination of tissues (“true” enamel and dentine) ...
In this paper, recursive constructions for cyclic BIB designs and for BIB designs with more general automorphism groups are discussed. First, a brief survey of cyclic BIB designs and 1-rotational BIB designs is given along with two types of recursive constructions for them. Secondly, it is shown...
Normative data from 113 participants, and cross-validation data from 49 additional participants, are presented for the Biber Cognitive Estimation Test (BCET), a 20-item test with five estimation questions in each of four categories: time/duration, quantity, weight, and distance. In Study 1, the ...
BIB designs are shown to be D-optimal for the joint estimation of treatment contrasts and block contrasts over the class of all connected designs with v treatments in b blocks and a total of n observations. As a result, the dual of any BIB design is seen to be D-optimal for the estimation of tre...
This contribution reports on the study of the pore space morphology in two early mature (VRr = 0.59 and 0.61) samples of Posidonia Shale from the Hils Syncline in Germany, using Broad Ion Beam (BIB) polishing and high resolution Scanning Electron Microscopy (SEM). This allows imaging pores with ...
This contribution reports on the distribution of in situ pore-water in preserved clay cores from Belgium (Boom Clay at HADES URF level and clay from the Pittem Member of the Gent Formation) and identification of typical pore-scale damage induced by drying.BIB–cryo-SEM (Broad Ion beam–cryogenic...
Four Haynesville Shale and four Bossier Shale samples were investigated using a combination of Scanning Electron Microscopy (SEM) and Broad Ion Beam (BIB) polishing. This approach enables the microstructure and porosity to be studied down to the mesopore size (
Two new nonpeptide angiotensin II (AII) receptor antagonists, 4'-[(2-n-butyl-6-cyclohexylaminocarbonylamino-benzimidazole-1-yl)-methyl] biphenyl-2-carboxylic acid (BIBS 39) and 2-n-butyl-1-[4-(6-carboxy-2,5-dichlorobenzoylamino)-benzyl]-6-N-(methylaminocarbonyl)-n-pentylamino-benzimidazole ...
With the help of first-principles calculations, we propose a new type of two dimensional (2D) topological insulator BiB with bilayer hexagonal lattice. Its dynamic stability was confirmed by the phonon spectrum. When spin-orbit coupling (SOC) effect is not considered, the low energy electronic s...
The 80% ethanol extract of roselle (Hibiscus sabdariffa Linn.), a medicinal plant in Thailand, was examined for antimutagenic and chemopreventive activity in a colon carcinogenesis model. It reduced about 60–90% of the mutagenicity induced by 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhI...
The metabolism of the carcinogen 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) has been investigated in rabbit liver S9. Two phase I metabolites, N2-OH-PhIP and 4′-OH-PhIP were identified based on UV and mass spectra and co-elution with reference standards. Fortification of the incubat...
This study investigates whether the previous observation that quercetin increases the transport of PhIP through Caco-2 monolayers in vitro could be confirmed in an in vivo rat model.Co-administration of 1.45 μmol PhIP/kg bw and 30 μmol quercetin/kg bw significantly increased the blood AUC(0–8...
