A population pharmacokinetic model was developed to describe alterations in ceftaroline brain disposition caused by meningitis healthy and methicillin-resistant Staphylococcus aureus (MRSA)-infected rats. Blood microdialysate samples were obtained after a single bolus dose of fosamil (20 mg/kg) administered intravenously.
Abstract Ivermectin (IVM) is one of the most widely used antiparasitic drugs worldwide and has become drug choice for anthelmintic tick treatment in beef cattle production. It known that pharmacokinetic parameters are fundamental to rational use a food safety these influenced by different factors. The aim this study was evaluate profile IVM Bos indicus , taurus crossbreed ( B. × ) kept under same field conditions possible impacts sex formulation (1% 3.15%). observed concentration...
Abstract In Brazil, the buffalo milk market has been growing. However, identity and quality standards have not established for this raw material, nor proper distinctions between bovine defined. Currently, State of Rio Grande do Sul (RS) only three producers that supply material officially marketed derivatives. The aim study was to determine in region. Samples were obtained biweekly from farm cooling tanks June 2017 August 2018, reach a total 69 samples. averages results physicochemical...
A bioanalytical LC-MS/MS method was developed and validated to determine ceftaroline in microdialysate samples from plasma brain. Ceftaroline separated using a C18 column mobile phase consisting of water acetonitrile, both with 5 mM ammonium formate acid formic 0.1%, eluted as gradient. monitored electrospray ionization operating on positive mode (ESI+) monitoring the transition 604.89 > 209.3 m/z. The showed linearity concentration range 0.5-500 ng/mL for brain 0.5-2500 coefficients...
Analytical methodology for quantification of 15 antiparasitic drugs and their respective metabolites in laying hen eggs was optimized validated. The method uses acetonitrile as solvent extraction, sodium chloride salting-out, low-temperature purification analysis by LC-MS/MS. A total 348 egg samples were collected 11 states Brazil 50% the presented residues, which albendazole, fipronil, fenbendazole, ivermectin, oxibendazole mebendazole. 12.4% considered non-compliant, residues quantified...
This study analyzed the residue depletion kinetics of ivermectin (IVM) in Nelore and crossbred (Nelore x Angus) cattle aiming to compare profiles between breeds evaluate levels at injection site. IVM 1%, a dose 0.2 mg/kg, was administered
Resumo A produção de leite bubalino é uma atividade que tem crescido nos últimos anos, principalmente devido às características físico-químicas apresentadas pelo leite, o segundo mais produzido no mundo. O objetivo deste trabalho foi implementar um sistema ordenha e monitorar os padrões identidade qualidade do na Estação Experimental Agronômica da Universidade Federal Rio Grande Sul. Amostras foram coletadas quinzenalmente entre meses junho novembro 2021, totalizando dez coletas. As médias...
Abstract Buffalo milk production is an activity that has grown in recent years, mainly due to the physicochemical characteristics found this type of milk, which second most produced world. The objective study was implement a milking system and monitor identity quality standards buffalo at Experimental Agronomic Station Federal University Rio Grande do Sul. Samples were collected fortnightly between June November 2021, totaling ten collections. means obtained end monitoring 4.84 g/100 g for...
