Rheotaxis of Biomphalaria Glabrata on vertical substrates and its role in the recolonization of habitats treated with molluscicides
(Fundação Oswaldo Cruz. Instituto Oswaldo Cruz., 2020)
Locomotion and righting behavior of sea stars: a study case on the bat star Asterina stellifera (Asterinidae)
(Universidad de Costa Rica, 2021)
Getting to and away from the egg, an interplay between several sperm transport mechanisms and a complex oviduct physiology
(Elsevier Ireland, 2020-12-01)
In mammals, the architecture and physiology of the oviduct are very complex, and one long-lasting intriguing question is how spermatozoa are transported from the sperm reservoir in the isthmus to the oocyte surface. In ...
Rheotaxis of Biomphalaria Glabrata on vertical substrates and its role in the recolonization of habitats treated with molluscicides
(Fundação Oswaldo Cruz. Instituto Oswaldo Cruz., 1988)
Os autores observaram exemplares de Biomphalaria glabrata subindo contra corrente em uma parede vertical de uma vala, constatando que os caramujos que apresentavam esse comportamento durante a aplicação de miluscicida neste ...
Mechanisms of the sperm guidance, an essential aid for meeting the oocyte
(AME Publishing, 2017-03)
In mammals, ejaculated spermatozoa must migrate into the female reproductive tract in order to reach and fertilize the oocyte (Figure 1). The number of spermatozoa that reach the oviductal isthmus (where they attach to ...
Sperm Chemotaxis in Mammals
(Bentham Science Publishers, 2015)
Sperm cells evolved to acquire a sophisticated motility structure called a flagellum which gives spermatozoa a self-propelling force. Nonetheless, in internal fertilizing species such as mammals, the length and complexity ...
Actividad antioxidante de la Silimarina y sus componentes (Silidianina, Silicristina y Silibinina) y su efecto sobre la conservación de semen porcino (Sus scrofa) refrigerado
(Universidad Nacional de ColombiaMedellín - Ciencias - Maestría en Ciencias - BiotecnologíaFacultad de CienciasMedellín, ColombiaUniversidad Nacional de Colombia - Sede Medellín, 2022-11)
Durante la refrigeración, el espermatozoide porcino puede experimentar estrés oxidativo, osmótico, químico y térmico, que afectan su capacidad fecundante. La adición de antioxidantes al diluyente espermático constituye una ...
