Brazilian green propolis doesn't have a beneficial effect on the cryopreservati...
Gomes, Henrique Albano Nogueira; Fernandes , Denilsa Pires; Barbosa, Brenna de Sousa; Izzo, Roberta Gonçalves; Santos, Fernanda Araujo dosThis study evaluated the effect of different concentrations of Brazilian green propolis on the cryopreservation of epididymal sperm from domestic cats. Spermatozoa were collected from cauda epididymis by slicing technique in a TRIS extender, preheated to 37ºC. Then, the sperm were evaluated and divided randomly between the control group (without adding propolis in the extender) and the treatment groups (adding ...
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...
Ultrastructural features of agouti (Dasyprocta aguti) preantral follicles cryop...
Wanderleya, Livia Schell; Luza, Hiédely Kenia Machado; Faustino, Luciana Rocha; Lima, Isadora Machado Teixeira; Lopes, Cláudio Afonso PinhoThe objective was to develop an efficient protocol for cryopreservation of agouti (Dasyprocta aguti) ovarian tissue. Agouti ovarian fragments were placed, for 10 min, in a solution containing MEM and fetal bovine serum plus 1.5 M dimethyl sulfoxide (DMSO), ethylene glycol (EG) or propanediol (PROH); some of those fragments were subsequently cryopreserved in a programmable freezer. After exposure and/or thawing,...
Correlation between weight, length and fetal membranes of rock cavies (Kerodon ...
Oliveira, Moacir Franco de; Oliveira, Gleidson Benevides de; Rodrigues, Márcio Nogueira; Bezerra, Ferdinando Vinícius FernandesFoi avaliada a existência de correlação entre diferentes anexos fetais de mocós e determinada a relação entre peso do feto e peso da placenta, relação entre o peso do feto e comprimento do cordão umbilical e a relação entre o peso do feto e comprimento do feto. Foram utilizados anexos fetais e fetos de três, cinco e seis fêmeas, respectivamente, no terço inicial, médio e final de gestação, obtidas no Centro de ...
Comparison between powder coconut water (ACP®) and Tris as extenders for canine...
Silva, Alexandre Rodrigues; Cardoso, Rita de Cássia Soares; Silva, Lúcia Daniel Machado daThe present study compared powder coconut water (ACP®) and Tris extenders on canine semen cryopreservation by classic evaluation and thermoresistance test. Five stud dogs were submitted to two semen collections by digital manipulation. Sperm fractions were analyzed regarding to its color, volume, sperm concentration, motility, vigor and morphology. Semen samples were divided into two aliquots: the first one was...
