Role of free L-carnitine and acetyl-L-carnitine in post-gonadal maturation of mammalian spermatozoa

Autor: C Jeulin, LM Lewin

Publikováno v: Human Reproduction Update. 2:87-102

Spermatozoa are produced in the testis and undergo post-gonadal modifications in the epididymis to acquire fertilizing ability. In epididymal plasma, high-molecular-weight proteins and such small molecules as free-L carnitine convert the gametes into

Morphological and kinetic changes of carp (Cyprinus carpio) spermatozoa after initiation of motility in distilled water

Autor: Marie-Paule Cosson, C. Jeulin, Roland Billard, G. Perchec, Jacky Cosson

Publikováno v: Cell Motility and the Cytoskeleton. 35:113-120

Studies on the flagellar movement of carp spermatozoa induced by dilution in distilled water allowed us to describe a sequence of early, rapid morphological and kinetic changes which begin at the very tip of the flagellum. They cause the progressive

Chantier qualité GA; International audience; Two lines of broilers divergently selected for a high (D+) or a low (D-) AME(n) on a wheat-based diet were studied for morphological and histological characteristics of the digestive tract. A total of 630

Effects of extracellular environment on the osmotic signal transduction involved in activation of motility of carp spermatozoa

Autor: Françoise Fierville, C. Jeulin, G. Perchec Poupard, Jacky Cosson, J. L. Gatti, Roland Billard

Publikováno v: Journal of Reproduction and Fertility
Journal of Reproduction and Fertility, Portland Press, 1997, 110, pp.315-327

The mechanism by which a hypo-osmotic shock activates motility of carp spermatozoa was studied. The direct role of osmolality at the axoneme was investigated after demembranation of spermatozoa with Triton X-100 and reactivation in various ionic or a

Changes in flagellar movement of rat spermatozoa along the length of the epididymis: manual and computer-aided image analysis

Autor: C, Jeulin, L M, Lewin, C, Chevrier, D, Schoevaert-Brossault

Publikováno v: Cell motility and the cytoskeleton. 35(2)

The different patterns of motility of rat spermatozoa during epididymal transit were studied in vitro using high-speed videomicroscopy. The sperm images were analysed after manual tracing as well as with a computer imaging system. The present work is

Relationship between sperm ATP content and motility of carp spermatozoa

Autor: Jacky Cosson, C. Jeulin, F. Andre, R. Billard, G. Perchec

Publikováno v: Journal of cell science. 108

Carp spermatozoa are immotile in seminal plasma or in saline solution of high osmolality (> 400 mosmol kg-1). These ‘quiescent’ spermatozoa initiate a progressive forward motility when transferred in freshwater or in saline solution with low osmo

In vitro exposure of rabbit tracheal epithelium to SO(2): Effects on morphology and ciliary beating

Autor: C. Blanquart, Francelyne Marano, C. Jeulin, Christiane Guennou, I. Giuliani, Odile Houcine

Publikováno v: Toxicology in vitro : an international journal published in association with BIBRA. 9(2)

The aim of this in vitro study was to characterize the direct effects of short-term exposure to low concentrations of sulfur dioxide (SO(2)) on both the morphology and the physiology of rabbit tracheal primary cultures. Scanning electron microscopy (
