Gamete activation: basic knowledge and clinical applications

BACKGROUND The first clues to the process of gamete activation date back to nearly 60 years ago. The mutual activation of gametes is a crucial event during fertilization. In the testis and ovaries, spermatozoa and oocytes are in a state of meiotic and metabolic quiescence and require reciprocal signals in order to undergo functional changes that lead to competence for fertilization. First, the ...

Transfer Factor. Basic Properties and Clinical Applications

included a review of some notable empirical evidence, analyzed and related in a wellthought out epidemiologic fashion. While the text is necessarily complex in parts, its appeal should not be limited; there is something in it to interest everyone. Perhaps a more rational and less zealous attitude concerning the use of marijuana, and its impact on us all, will accompany a widespread reading of t...

Aberrometry: basic science and clinical applications.

This paper addresses the concept, measurement and applications of wave aberrations. The ocular optics is not perfect. Apart from conventional low order aberrations (such as defocus and astigmatism) retinal images are degraded by other high order aberrations. Aberrometers typically measure ray deviations at the retinal plane, as a function of pupil position, i.e. local derivatives of the wave ab...
