Pharmacokinetics of S-ketamine and R-ketamine and their active metabolites after racemic ketamine or S-ketamine intravenous administration in dogs sedated with medetomidine
No full textObjective: To assess the differences in the pharmacokinetic profiles of S-ketamine, R-ketamine and their metabolites, S-norketamine and R-norketamine, and to measure relevant physiologic variables after intravenous administration of racemic (RS) ketamine or S-ketamine alone in Beagle dogs sedated with medetomidine. Study design: Experimental, blinded and randomized crossover study. Animals: A total of six (three female and three male) adult Beagle dogs. Methods: Medetomidine (450 μg m–2) was administered intramuscularly, followed by either S-ketamine (2 mg kg–1) or RS-ketamine (4 mg kg–1) 20 minutes later, both administered intravenously. Blood samples were collected before medetomidine administration and at multiple time points 1–900 minutes following the ketamine administration. Plasma samples were analysed using liquid chromatography–tandem mass spectrometry. Heart rate, respiratory rate, noninvasive blood pressure, haemoglobin saturation with oxygen and body temperature were measured at baseline, before ketamine administration, and 1, 2, 5, 10, 15, 20 and 30 minutes after ketamine administration. All cardiovascular variables, blood glucose, haemoglobin and lactate concentrations were analysed using different linear mixed effects models; the significance was set at p < 0.05. Results: S-ketamine showed a two-compartment kinetic profile; no statistically significant differences were observed between its concentrations or in the calculated pharmacokinetic parameters following S- or RS-ketamine. When the racemic mixture was administered, no differences were detected between R- and S-ketamine concentrations, but the area under the curve (AUC) for R-norketamine was significantly lower than that for S-norketamine. Clinically relevant physiologic variables did not show statistically significant differences following the administration of the racemic mixture or of S-ketamine alone. Conclusions and clinical relevance: This study performed in dogs showed that RS-ketamine and S-ketamine combined with medetomidine showed enantioselective pharmacokinetics as S- and R-norketamine AUCs were different, but S-ketamine levels were identical

Isolation and characterization of a new T-even bacteriophage, CEV1, and determination of its potential to reduce Escherichia coli O157:H7 levels in sheep
No full textBacteriophage CEV1 was isolated from sheep resistant to Escherichia coli O157:H7 colonization. In vitro, CEV1 efficiently infected E. coli O157:H7 grown both aerobically and anaerobically. In vivo, sheep receiving a single oral dose of CEV1 showed a 2-log-unit reduction in intestinal E. coli O157:H7 levels within 2 days compared to levels in the controls.

No full textThis paper presents a summary of the element test simulations (calibration simulations) submitted by 11 numerical simulation (prediction) teams that participated in the LEAP-2017 prediction exercise. A significant number of monotonic and cyclic triaxial (Vasko, An investigation into the behavior of Ottawa sand through monotonic and cyclic shear tests.

The focus of this element test simulation exercise is to assess the performance of the constitutive models used by participating team in simulating the results of undrained stress-controlled cyclic triaxial tests on Ottawa F-65 sand for three different void ratios (El Ghoraiby et al., LEAP 2017: Soil characterization and element tests for Ottawa F65 sand. The George Washington University, Washington, DC, 2017; El Ghoraiby et al., LEAP-2017 GWU Laboratory Tests.

(Eds.), Model tests and numerical simulations of liquefaction and lateral spreading: LEAP-UCD-2017. New York: Springer, 2019). The simulated stress paths, stress strain responses, and liquefaction strength curves show that majority of the models used in this exercise are able to provide a reasonably good match to liquefaction strength curves for the highest void ratio (0.585) but the differences between the simulations and experiments become larger for the lower void ratios (0.542 and 0.515)

Hylomyrma reginae is unlikely to be confused with any other congener because of its very prominent and subtriangular subpostpetiolar process. Two specimens collected in Upper Takutu-Upper Essequibo, Guyana (USNMENT00688778, USNMENT00689009) were designated as intercaste because of the larger body measures [HL (1.16); HW (1.16–1.17); ML (0.76–0.78); SL (0.82–0.84); MOD (0.27–0.28); PNW (0.83–0.84); WL (1.64); PSL (0.34–0.35); PL (0.82– 0.85); PW (0.36–0.38); PPL (0.36); PPW (0.40); GL (1.30); TL (6.04–6.09)], and for having one central and inconspicuous ocellus. Distribution. All known specimens were collected in northern South America (Brazil, French Guiana, Guyana, and Suriname) (Fig. 86). Natural history. This species is recorded from tropical rainforests (in the Amazon and in Inselberg forests; primary and secondary forests) at elevations between 60 and 1051 m. Specimens are frequently found in leaf-litter samples, which suggests that nests are located in fallen logs, rotten wood, between leaves, or inside natural cavities of the superficial soil layers. Except for the presence of intercastes, there is no further information available regarding the biology of H. reginae.
