Event self-importance, event rehearsal, and the fading affect bias in autographical memory.
Prior research suggests that the negative affect associated with autobiographical memories fades faster across time than the positive affect associated with such memories (i.e., the fading affect bias, FAB). Data described in the present article reveal several moderators of this bias. The FAB is small when events are perceived to be self-important, psychologically open, or self-caused; it is large when events are perceived to be atypical of a person's life. The data also suggest that the FAB is especially large when events are rehearsed in the course of conveying events to others, or when events are being privately savored or solved; this effect does not emerge for various other forms of private rehearsal. Theoretical implications of these results are discussed

Actin-based dynamics during spermatogenesis and its significance*
Actin can be found in all kinds of eukaryotic cells, maintaining their shapes and motilities, while its dynamics in sperm cells is understood less than their nonmuscle somatic cell counterparts. Spermatogenesis is a complicated process, resulting in the production of mature sperm from primordial germ cell. Significant structural and biochemical changes take place in the seminiferous epithelium of the adult testis during spermatogenesis. It was proved that all mammalian sperm contain actin, and that F-actin may play an important role during spermatogenesis, especially in nuclear shaping. Recently a new model for sperm head elongation based on the acrosome-acroplaxome-manchette complex has been proposed. In Drosophila, F-actin assembly is supposed to be very crucial during individualization. In this mini-review, we provide an overview of the structure, function, and regulation characteristics of actin cytoskeleton, and a summary of the current status of research of actin-based structure and movement is also provided, with emphasis on the role of actins in sperm head shaping during spermiogenesis and the cell junction dynamics in the testis. Research of the Sertoli ectoplasmic specialization is in the spotlight, which is a testis-specific actin-based junction very important for the movement of germ cells across the epithelium. Study of the molecular architecture and the regulating mechanism of the Sertoli ectoplasmic specialization has become an intriguing field. All this may lead to a new strategy for male infertility and, at the same time, a novel idea may result in devising much safer contraception with high efficiency. It is hoped that the advances listed in this review would give developmental and morphological researchers a favorable investigating outline and could help to enlarge the view of new strategies and models for actin dynamics during spermatogenesis
