Pharmacokinetic study of long-acting oxytetracycline in cows. Estudio cinético de oxitetraciclina de larga acción en bovinos de Iechería
(1996)
Pharmacokinetics of a long-acting formula of oxytetracycline (OTC) in one formulation of dymetylacetomide, was studied in seven-cows after i.m. administration (20 mg/kg of body weight). Serum OTC concentration was measured ...
Influence of Bleaching Gel Peroxide Concentration on Color and Penetration through the Tooth Structure
(2021-05-01)
AbstraAct Aim and objective: The purpose of this study was to assess the effect of hydrogen peroxide concentration on the bleaching efficacy and penetration through the tooth structure. Materials and methods: One hundred ...
Relationship between ivermectin concentrations at the injection site, muscle and fat of steers treated with traditional and long-acting preparations
(Pergamon-Elsevier Science Ltd, 2017-07)
Ivermectin (IVM) is broad-spectrum compound active against endo and ecto-parasites of clinical relevance in veterinary and human medicine. It is commercially available to use in livestock animals as injectable formulations ...
Delay nonlinear boundary conditions as limit of reactions concentrating in the boundary
(ACADEMIC PRESS INC ELSEVIER SCIENCESAN DIEGO, 2012)
In this work, we are interested in the dynamic behavior of a parabolic problem with nonlinear boundary conditions and delay in the boundary. We construct a reaction-diffusion problem with delay in the interior, where the ...
Melatonin in Arabidopsis thaliana acts as plant growth regulator at low concentrations and preserves seed viability at high concentrations
(Elsevier France-editions Scientifiques Medicales Elsevier, 2015-09-12)
Since the discovery of melatonin in plants, several roles have been described for different species, organs, and developmental stages. Arabidopsis thaliana, being a model plant species, is adequate to contribute to the ...
Influence of the concentration of Sb2O3 on the electrical properties of SnO2 varistors
(2011)
Varistors are electronic materials with nonohmic behavior. In traditional SnO2 varistors, CoO acts as a densifying agent, Nb2O5 increases the electrical conductivity of SnO2 grains, and Cr2O3 produces a more uniform ...
Differences in the hydroxylation pattern of flavonoids alter their chemoprotective effect against direct- and indirect-acting mutagens
(Elsevier B.V., 2014-07-15)
The antimutagenicity of ten flavonoids, differing in their hydroxylation patterns against direct-acting and indirect-acting mutagens, namely 4-nitro-o-phenylenediamine, sodium azide, mitomycin C, benzo[a]pyrene, aflatoxin ...
Comparison of different regimens of estradiol benzoate treatments followed by long-acting progesterone to prepare noncycling mares as embryo recipients
(Elsevier B.V., 2016-10-15)
The present study evaluated the influence of different regimens of estradiol benzoate (EB) treatments followed by a single dose of long-acting progesterone (LA P4) on plasma estrogen and P4 concentrations in noncyclic mares ...
The anthelmintic pyrantel acts as a low efficacious agonist and an open-channel blocker of mammalian acetylcholine receptors
(Pergamon-Elsevier Science Ltd, 2001-08)
Pyrantel is an anthelmintic which acts as an agonist of nicotinic receptors (AChRs) of nematodes and exerts its therapeutic effects by depolarizing their muscle membranes. Here we explore at the single-channel level the ...
