MicroRNAs: crucial regulators of placental development
Reproduction - Tập 155 Số 6 - Trang R259-R271 - 2018
Heyam Hayder, Jacob A. O’Brien, Uzma Nadeem, Chun Peng
MicroRNAs (miRNAs) are small non-coding single-stranded RNAs that are integral to a wide range of cellular processes mainly through the regulation of translation and mRNA stability of their target genes. The placenta is a transient organ that exists throughout gestation in mammals, facilitating nutrient and gas exchange and waste removal between the mother and the fetus. miRNAs are express...... hiện toàn bộ

Effects of cryopreservation on semen quality and the expression of sperm membrane hexose transporters in the spermatozoa of Iberian pigs
Reproduction - Tập 134 Số 1 - Trang 111-121 - 2007
S. Sancho, Isabel Casas, H. Ekwall, F. Saravia, Heriberto Rodríguez‐Martinez, Joan E. Rodríguez‐Gil, E. Flores, Elisabeth Pinart, M. Briz, N. García-Gil, Judit Bassols, A Pruneda, E Bussalleu, Marc Yeste, Sergi Bonet
This study evaluated the effects of cooling, freezing and thawing on the plasma membrane integrity, kinetics and expression of two sugar transporters glucose transporter-3 and -5 (GLUT-3 and GLUT-5) in spermatozoa from Iberian boars. Semen samples were collected twice weekly from eight young, fertile Iberian boars of the ‘Entrepelado’ and ‘Lampiño’ breeds. The samples were suspended in a ...... hiện toàn bộ
Changes in sperm quality and lipid composition during cryopreservation of boar semen
Reproduction - Tập 121 Số 3 - Trang 395-401 - 2001
Silvia Cerolini, A. Maldjian, F. Pizzi, T. M. Gliozzi
The effect of cryopreservation on boar sperm viability, motility, lipid content and antioxidant enzymatic activities was studied. Three classes of semen were determined according to a cluster analysis on the basis of the proportion of live and dead cells after freezing and thawing. The classes identified were: high (H, n = 4), average (A, n = 12) and low (L, n = 3) viability. The concentra...... hiện toàn bộ
Induced hyperactivity in boar spermatozoa and its evaluation by computer-assisted sperm analysis
Reproduction - Tập 128 Số 2 - Trang 171-179 - 2004
Harald Schmidt, Günter Kamp
Hyperactivity, a form of sperm motility characterized by vigorous flagellar movements, has been proposed as essential for fertilization in mammals. The objective of the present study was to establish a method for inducing hyperactivityin vitroin boar spermatozoa and to define threshold values to differentiate between hyperactive and non-hyperactive spermatozoa by...... hiện toàn bộ
