Functional significance of responsiveness to capacitating conditions in boar spermatozoa.
TLDR
The combination of sperm responsiveness parameters applied here is a suitable tool for the evaluation of sperm function and improved the prediction level of multiple regression models for farrowing rate and litter size.About:

Journal ArticleDOI
Effects of exposure to triphenyltin (TPT) contaminant on sperm activity in adulthood of Calomys laucha exposed through breastfeeding
Tiane Ferreira de Castro,Antonio Sergio Varela Junior,Francine Ferreira Padilha,Daniela Droppa-Almeida,Graciela Quintana Saalfeld,Diego Martins Pires,Jessica Ribeiro Pereira,Carine Dahl Corcini,Elton Pinto Colares +8 more
TL;DR: The TPT causes alteration of the reproductive parameters, decreasing the activity and sperm quality in individuals exposed in the breastfeeding phase, and presents a reduction in total motility in the groups exposed to TPT.
Tecnologias aplicadas no exame do ejaculado suíno para a produção de doses de sêmen de alta qualidade Technologies used in the assessment of boar ejaculate to produce high quality semen doses
TL;DR: In this article, analises da morfologia e motilidade progressiva sao exames rotineiros for avaliar a qualidade do semen em centrais de IA.
Journal ArticleDOI
Evaluation of common in vitro used chemicals' effect on motility and chromatin stability of boar spermatozoa
Ioannis Tsakmakidis,T. A. A. Khalifa,A. G. Lymberopoulos,Ilias Michos,C. M. Boskos (Κ.Μ. Μποσκοσ) +4 more
TL;DR: In this paper, the authors proposed a method to measure the effectiveness of a drug in terms of its effect on the performance of the drug in vitro and in the field of in vitro drug development.
Journal ArticleDOI
A High Incidence of Sperm with Cytoplasmic Droplets Affects the Response to Bicarbonate in Preserved Boar Semen.
TL;DR: In this paper, the authors examined whether the enhanced presence of cytoplasmic droplets (CD) in boar semen influences sperm's response to the capacitation stimulus bicarbonate during long-term semen storage.

Buriticá Henao,María Elizabet +1 more
TL;DR: The AEA puede ser utilizada in los procesos de crio-congelacion de espermatozoides porcinos para controlar the presentacion of crio–capacitacion of espermaozoides congelados - descongelados.

TL;DR: The gametes, fertilization and early embryogenesis the reproductive systems - the female, the male the pituitary and the hypothalmus, and the reproductive processes and their control.
Journal ArticleDOI
Use of fluorescent probes to assess membrane integrity in mammalian spermatozoa
TL;DR: The technique appeared to provide more reliable estimations of the percentage of functional cells than did motility estimations or assessments of acrosomal integrity, and demonstrated the sensitivity of the sperm plasma membrane to cold shock: virtually all cells rapidly became permeable to the stains after such stress.
Journal ArticleDOI
Cholesterol efflux-mediated signal transduction in mammalian sperm: cholesterol release signals an increase in protein tyrosine phosphorylation during mouse sperm capacitation.
Pablo E. Visconti,XiaoPing Ning,Miguel W. Fornés,Juan G. Alvarez,Paula Stein,Stephanie A. Connors,Gregory S. Kopf +6 more
TL;DR: It is demonstrated that cholesterol release is associated with the activation of a transmembrane signal transduction pathway involving PK-A and protein tyrosine phosphorylation, leading to functional maturation of the sperm.
Journal ArticleDOI
Bicarbonate/CO2, an effector of capacitation, induces a rapid and reversible change in the lipid architecture of boar sperm plasma membranes
TL;DR: It is found that bicarbonate causes a rapid increase in the ability of live boar spermatozoa to bind merocyanine, apparently by perturbing enzymic control processes.
Journal ArticleDOI
Evaluation of in vitro capacitation of stallion spermatozoa.
TL;DR: It was found that merocyanine 540 detects capacitation-related changes much earlier than CTC does, and that flow cytometry for evaluation of capacitation and AR was a quicker and more accurate technique than fluorescence microscopy.
