PURPOSE Sperm processing (e.g., centrifugation) used in preparation for assisted reproduction can result in excessive generation of reactive oxygen species (ROS) and potential sperm damage. The use of antioxidants during sperm processing has been shown to prevent iatrogenic sperm damage, including DNA damage. In this study, we evaluated the effect of caffeic acid phenethyl ester (CAPE) on oxida...

AIM The purpose of this study was to evaluate the effects of caffeic acid phenethyl ester (CAPE) on palatal mucosal defects and tooth extraction sockets in an experimental model. MATERIALS AND METHODS Forty-two male Sprague-Dawley rats with a mean age of 7 weeks and weighing 280-490 g were used in this study. The rats were randomly divided into two groups: group A (the control group, n=21) an...

Fire has had a profound effect on the evolution of worldwide biotas. The Cape Floristic Region is one of the world's most species-rich regions, yet it is highly prone to recurrent fires and fire-adapted species contribute strongly to the overall flora. It is hypothesized that the current fire regimes in the Cape could be as old as 6-8 million years (My), while indirect evidence indicates that t...

Recently, both Rennó and Ingersoll (1996, hereafter RI) and Emanuel and Bister (1996, hereafter EB) derive theoretical formulas for the convective available potential energy (CAPE), the fractional area covered by active updrafts, and the vertical velocity in the active updrafts for atmospheres in radiative–convective equilibrium. The theories of RI and EB differ primarily in the means of closur...

The Cape Floristic Region is exceptionally species-rich both for its area and latitude, and this diversity is highly unevenly distributed among genera. The modern flora is hypothesized to result largely from recent (post-Oligocene) speciation, and it has long been speculated that particular species-poor lineages pre-date this burst of speciation. Here, we employ molecular phylogenetic data in c...

The active component of the honeybee hive product propolis, caffeic acid phenethyl ester (CAPE), induces a selective growth suppressive and toxic effect toward cloned rat embryo fibroblast cells transformed by adenovirus type 5 (Ad5) or the Ad5 E1A transforming gene versus untransformed cloned rat embryo fibroblast cells (Z-z. Su et al., Mol. Carcinog., 4: 231-242, 1991). The present study was ...

Four species of Rhimphoctona (Xylophylax) collected from P. R. China are reported. Two of them are new to science: Rhimphoctona (Xylophylax) maculifemoralis Luo and Sheng, sp.nov. reared from Tetropium castaneum (Linnaeus), and Rhimphoctona (Xylophylax) immaculata Luo and Sheng, sp.nov. One is a new record for China, R. (Xylophylax) rufocoxalis ( Clément 1924 ) reared from T. castaneum (Linnaeu...

This article describes a method of moral counselling developed in the Radboud University Medical Centre Nijmegen (The Netherlands). The authors apply insights of Paul Ricoeur to the non-directive counselling method of Carl Rogers in their work of coaching patients with moral problems in health care. The developed method was shared with other health care professionals in a training course. Exper...
