Subgenera of Charidotella Weise with description of a new subgenus and species from Brazil (Coleoptera, Chrysomelidae, Cassidinae, Cassidini)
A new subgenus and species, Charidotella (Chapadacassis subgen. n.) paradoxasp. n. is described and figured from the Chapada plateau in Mato Grosso, Brazil. Subgenera of Charidotella Weise, 1896 are listed, supplemented with basic data, diagnostic table, and a key is proposed. Based on a study of respective type material following new combinations are proposed: Charidotella (Philaspis) stulta (...
متن کاملWhole-Genome Sequence and Annotation of Octopine-Utilizing Pseudomonas kilonensis (Previously P. fluorescens) Strain 1855-344
Here, we report the whole-genome sequence and annotation of Pseudomonas kilonensis 1855-344 (previously known as P. fluorescens 1855-344). The genome contains an octopine oxidase gene cluster consistent with the ability to utilize octopine. A biosynthetic gene cluster was identified for mangotoxin and aryl-polyene using the antiSMASH server.
متن کاملComparative effects of levosimendan, OR-1896, OR-1855, dobutamine, and milrinone on vascular resistance, indexes of cardiac function, and O2 consumption in dogs.
Levosimendan enhances cardiac contractility via Ca(2+) sensitization and induces vasodilation through the activation of ATP-dependent K(+) and large-conductance Ca(2+)-dependent K(+) channels. However, the hemodynamic effects of levosimendan, as well as its metabolites, OR-1896 and OR-1855, relative to plasma concentrations achieved, are not well defined. Thus levosimendan, OR-1896, OR-1855, or...
متن کاملEvoked changes in cardiovascular function in rats by infusion of levosimendan, OR-1896 [(R)-N-(4-(4-methyl-6-oxo-1,4,5,6-tetrahydropyridazin-3-yl)phenyl)acetamide], OR-1855 [(R)-6-(4-aminophenyl)-5-methyl-4,5-dihydropyridazin-3(2H)-one], dobutamine, and milrinone: comparative effects on peripheral resistance, cardiac output, dP/dt, pulse rate, and blood pressure.
Levosimendan enhances cardiac contractility primarily via Ca(2+) sensitization, and it induces vasodilation through the activation of ATP-sensitive potassium channels and large conductance Ca(2+)-activated K(+) channels. However, the concentration-dependent hemodynamic effects of levosimendan and its metabolites (R)-N-(4-(4-methyl-6-oxo-1,4,5,6-tetrahydropyridazin-3-yl)phenyl)acetamide (OR-1896...
