F-ACTIN IN ACROSOME-REACTED BOAR SPERMATOZOA
No full text8. L. Castellani Ceresa, M. F. Brivio, G. Radaelli. F Actin in Acrosome Reacted Boar Spermatozoa. Molecular Reproduction and Development, 33, 99 107, 1992.Biochemical and immunoelectron microscopic methods have been used to analyze the distribution of actin in boar spermatozoa and its state of aggregation before and after acrosome reaction. F-actin was detected on sperm head and tail by electron microscopy using an improved phalloidin probe: incubation with a fluorescein-phalloidin complex and an anti-fluorescein antibody, followed by labeling with protein A-gold complex. Gold particles, indicating the presence of F-actin, were localized on the sperm surface of the acrosome-reacted spermatozoa. Specific labeling was localized (1) between the outer acrosomal membrane and the plasma membrane in the equatorial region, (2) between the outer surface of the fibrous sheath and the plasma membrane in the postacrosomal region, (3) around the connecting piece and the neck region, and (4) on the external surface of the fibrous sheath in the principal piece of the tail. Furthermore, after NP-40 extraction, the SDS-PAGE revealed a difference in solubility between reacted and unreacted boar spermatozoa, reflecting actin polymerization. We conclude that most actin in the acrosome reacted boar spermatozoa is polymeric

Degree Variance And Emotional Strategies Catalyze Cooperation In Dynamic Signed Networks
No full textWe study the problem of the emergence of cooperation in dynamic signed networks where agent strategies coevolve with relational signs and network topology. Running simulations based on an agent-based model, we compare results obtained in a regular lattice initialization with those obtained on a comparable random network initialization. We show that the increased degree heterogeneity at the outset enlarges the parametric conditions in which cooperation survives in the long run. Furthermore, we show how the presence of sign-dependent emotional strategies catalyze the evolution of cooperation with both network topology initializations.

ELECTRON-MICROSCOPIC LOCALIZATION OF F-ACTIN IN ACROSOME REACTED BOAR SPERMATOZOA BY MEANS OF A PHALLOIDIN-FITC COMPLEX
No full text7. L. Castellani Ceresa, M. F. Brivio, G. Radaelli. Electron Microscopic Localization of F actin in Acrosome Reacted Boar Spermatozoa by Means of a Phalloidin FITC Complex. J. Submicrosc. Cytol. Phatol., 23, n°2, 347 349, 1991.An immunocytochemical study at the ultrastructural level has been performed in boar spermatozoa in order to clarify the aggregation state of actin before and after the acrosome reaction. A new phalloidin probe has been used to detect F-actin: a phalloidin derivative conjugated with FITC, followed by incubation with an anti-FITC antibody. The protein A-gold technique was then applied for the localization of the antigenic sites. Gold particles were localized on the sperm surface only after the acrosome reaction which was induced by the ionophore A23187
