Long-term preservation of established fibroblast lines from six-banded armadillos (Euphractus sexcintus, Linnaeus, 1758) by extended passage and cryopreservation.

Establishing new somatic cell cultures has raised significant attention as an effective and convenient way to preserve genetic samples for different applications. Although many lines have been established in model animals, none derived from six-banded armadillo species is currently available. We report the successful isolation and characterization of fibroblasts from six-banded armadillos, evaluating the cell quality after extended culture and cryopreservation.

Chemical composition variation of essential oils of Desf. from different vegetational formations.

This study aims to provide information about the chemical profile of the essential oil from resin in areas of , , and Humid Forest. In order to obtain the essential oils, oil-resin was submitted to hydrodistillation process, and the chemical components were analyzed by gas chromatography coupled to mass spectrometry (GC/MS). Twenty-six constituents were identified in the essential oil of resin, of which 12 were present in , 15 in and 18 in Humid Forest, with β-bisabolene, caryophyllene oxide, γ-muurolene, α-caryophyllene and β-caryophyllene common to the three phytophysiognomies.

Therapeutic indications, chemical composition and biological activity of native Brazilian species from Psidium genus (Myrtaceae): A review.

Ethnopharmacological Importance: Brazilian medicinal species of the Psidium genus are rich in secondary metabolites such as terpenes and phenolic compounds and present biological activities for several human diseases. For the native Psidium species, there are no specific research reports for any member of the genus about ethnobotanical research, hindering the joint analysis of its therapeutic indications together with the scientific evidence already investigated.

Study Objective: Analyze the therapeutic indications, the main chemical constituents, and the biological activities of native species of the Psidium to Brazil.
