Progressos e perspectivas da criopreservação da pele de mamíferos como estratég...
Borges, Alana Azevedo; Pereira, Alexsandra FernandesThe cryopreservation of skin is an interesting tool for the conservation of animal biodiversity. In this context, different protocols have been employed and methodological adjustments, especially on the type and the concentration of the cryoprotectants, are constantly being developed for both domestic and wild mammals. Although both methods of cryopreservation, freezing and vitrification, have been used for tis...
Superoxide dismutase and catalase activity in collared peccary (Pecari tajacu) ...
Santos, Érika Aparecida Araújo dos; Sousa, Patrícia Cunha; Silva, Andreia Maria da; Paiva, Ariana Lopes Correia; Lago, Arthur Emmanuel de AraújoThe study of the seminal plasma help us to understand the mechanisms by which reactive oxygen species (ROS) affect the sperm. The antioxidant enzymes, as the superoxide dismutase - SOD and catalase - CAT, are capable of removing the oxidative agents before they produce injuries. The aim of the current study was to investigate the activity of antioxidant enzymes SOD and CAT in seminal plasma, and their associati...
The placental barrier of Kerodon rupestris (Rodentia: caviidae)
Oliveira, Moacir Franco de; Oliveira, Gleidson Benevides de; Bezerra, Ferdinando Vinícius Fernandes; Câmara, Felipe VenceslauThe placenta of the rodents generally has a chorial-allantoic, discoid and hemochorial shape. Since they resemble the process of human placentation, such characteristics make this order an interesting experimental model for understanding placentation, placental barrier and the physiological mechanisms involved in maternal-fetal exchanges. Due to the fact that Kerodon rupestris may be used as placental model, cu...
Ultrasonographic findings of the mammary gland, liver, gallbladder, spleen, and...
Sousa, Francisco Carlos de; Melo, Carlos Henrique Sousa de; Batista, Ribrio Ivan Tavares Pereira; Sanchez, Deisy Johana DiazIn transgenic murine models, the study of certain organs or tissues can be performed after euthanasia of some specimens. However, this practice may not be economically feasible when applied to livestock such as transgenic goats. It is necessary to use minimally invasive methods to perform in vivo studies of organs that may be affected by disorders related to the activity of the transgene, particularly during mi...
