In vitro antimicrobial activity of a new series of 1,4-naphthoquinones
(2002) [Artigo de periódico]The antibacterial activity of a series of 1,4-naphthoquinones was demonstrated. Disk diffusion tests were carried out against several Gram-positive and Gram-negative bacteria. The compound 5-amino- 8-hydroxy-1,4-naphthoquinone ... -
In vitro differentation of embryonic stem cells into cardiac-like and neuronal-like cells
(2008) [Artigo de periódico]Células-tronco embrionárias são linhagens celulares pluripotentes capazes de se multiplicar indefinidamente e com grande capacidade de diferenciação celular. São isoladas de embriões em estágio pré-implantacional e podem ... -
In vitro differentiation of embryonic stem cells into cardiac-like and neuronal-like cells
(2008) [Artigo de periódico]Embryonic stem cells are pluripotent cell lines with the capacity of self-renewal and a broad differentiation plasticity. They are isolated from preimplantation embryos and can be cultured in vitro for long time without ... -
In vitro efficiency of disinfectants against salmonella enteritidis samples isolated from broiler carcasses
(2008) [Artigo de periódico]The threat to public health represented by Salmonella is at least partially a consequence of its ecology in poultry hosts. Good manufacturing practices in the processing plant can reduce the contamination of poultry products, ... -
In vitro evaluation of antimicrobial activities of Eugenia caryophyllata and origanum vulgare against avian Escherichia coli isolates
(2015) [Artigo de periódico]Background: The use of conventional antibiotics to prevent this infection is a usual in the poultry industry, specially to reduce the mortality associated with colibacillosis. Essential oils have demonstrated broad spectrums ... -
In vitro evaluation of essential oils derived from Piper nigrum (Piperaceae) and Citrus limonum (Rutaceae) against the tick Rhipicephalus (Boophilus) microplus (Acari: Ixodidae)
(2017) [Artigo de periódico]The present research aimed to study the chemical composition and acaricidal activity of Citrus limonum and Piper nigrum essential oils against the cattle tick Rhipicephalus microplus. GC-MS analysis of C. limonum essential ... -
In vitro method to evaluate virus competition between BVDV-1 and BVDV-2 strains using the PrimeFlow RNA assay
(2019) [Artigo de periódico]Bovine viral diarrhea viruses (BVDV), segregated in BVDV-1 and BVDV-2 species, lead to substantial economic losses to the cattle industry worldwide. It has been hypothesized that there could be differences in level of ... -
