Objective: To study the phytochemical and anxiolytic property of Cow urine Betel vine extract in albino mice. Methods: The anxiolytic activity of Cow urine Betel vine extract at (250 and 500mg/kg, p.o) in mice was assessed by using elevated plus-maze and light –dark model. Results: The Cow urine Betel vine extract significantly reduces the duration of time spent in the closed arm in Elevated plus-maze model and decreased entries into dark chamber in the Light-Dark model at the doses of 250 and 500mg/kg respectively.
Objetivou-se por esse estudo determina a melhor equação que estime a área de folhas de tomateiro das cultivares (Solanum Iycopersicum) mestiço e ozone através das medidas do comprimento e largura da superfície foliar. Um total de 800 folhas foram utilizadas, onde se obteve suas medidas do comprimento (C), largura (L), área foliar observadas (AFO) e produto da multiplicação do comprimento com a largura (CL). Foram testados os modelos linear de primeiro grau e potencia, obtidos através de AFO como variável dependente em função de C, L ou CL com amostra de 700 folhas.
The aim of this study was to evaluate the effects of different levels of nitrogen in deferred Brachiaria (Syn.Urochloa) brizantha cv. Marandu pastures on the intake, digestibility, and performance of Nellore heifers. A completely randomized design was adopted, with four treatments (nitrogen levels) and four replicates (number of fertilized paddocks). Initially, 48 Nellore heifers with an average age of 8 months and with an initial body weight of 179 kg were distributed at the rate of three animals per paddock into all treatments in a continuous grazing system with variable stocking rate.
This study has shown that the time tendencies of the earth surface atmospheric pressure in the southern part of Chad strictly occur in the interval 955.0 – 985.0 hPa and this variability is negligible as indicated by the low values of their standard deviation. It also indicates that one can accurately estimate missed data of the earth surface atmospheric pressure by the average values of its monthly or yearly means.
The effects of spatially varying temperature on resident birds of Ethiopia was evaluated. The resident bird data was treated at the guild level and the response variable was guild species richness. The guilds considered were granivores, frugivores, insectivores and raptors. The species richness of all the guilds considered declined significantly in response to spatially increased temperature.
Trypanosomaevansi causes a highly pathogenic disease in equines popularly known as "Surra". In Brazilian Pantanal, outbreaks are recorded due to the large population of horses. Losses to livestock are due to inefficient treatments. Trypanosomes are vulnerable to purine metabolism because they do not have the De novopathway and they satisfy their requirements by salvaging the preformed bases demonstrating acomplete purine dependence on their hosts. Among the components of this system, we highlight Adenosine,which has its concentration controlled by the enzyme Adenosine Deaminase (ADA).
Background: Staphylococcus aureus is a Gram-positive bacterium responsible for the development of infections of varying degrees of complexity. In addition, due to resistance phenomena, treatment against this pathogen has become increasingly ineffective, making it necessary to search for new molecules with antibacterial activity. Objective: The present study aims to evaluate isoeugenol antibacterial activity against clinical strains of Staphylococcus aureus through in vitro assays.
Resumo: Refletir acerca das estratégias de ensino-aprendizagem utilizadas na graduação de enfermagem no processo ensino-aprendizagem. Método: Trata-se de um artigo de revisão narrativo, com enfoque reflexivoque foi suportada pela referencial teórico de Paulo Freire. Os procedimentos para a construção da reflexão foram: seleção do tema central para ponderação, discussão e seleção de publicação nacionais e internacionais que fossem alinhados ao tema e ao referencial teórico capazes de permitir a discussão.
According to the opinion of the leading experts in the field of Cyber Security over the last few years there has been a transition from the stage of Cyber Criminality to the stage of Cyber War. In order to respond adequately to the new challenges, the expert community has two main approaches: to adopt the philosophy and methods of Military Intelligence, and to use Artificial Intelligence methods for counteraction of Cyber Attacks.
