Parameters for curvilineared residual strength envelope

Seiichi GIBO, S. Nakamura

The residual friction coefficient was found to decrease with the increasing effective normal stress at the lower half of the effective normal stress, while it was constant at the higher half. Based on this finding, the curvilinered residual strength envelope was divided …

Microtubule organization during rabbit fertilization by intracytoplasmic sperm injection with and without sperm centrosome

Junko Morita, Yukihiro Terada, Yoshihiko Hosoi, Nahoko Fujinami et autres

Aim: In most mammalian fertilization, the sperm introduces the centrosome, which acts as a microtubule organizing center (MTOC) and is essential for pronuclear movement. In rabbit fertilization, biparental centrosomal contribution in microtubule organization has been suggested. Methods: To reveal the function and …

Human Sperm Aster Formation and Chromatin Configuration in Rabbit Oocytes Following Intracytoplasmic Sperm Injection Using a Piezo-Micromanipulator

Fardin Amidi, A Abolhassani, Yukihiro Terada, Azim Hedayatpour et autres

In human fertilization, the sperm centrosome nucleates a radial array of microtubules called the sperm aster. The sperm aster is responsible for apposition of male and female pronuclei, and later gives rise to the first meiotic spindle. The objective of this study …

INTRACYTOPLASMIC SPERM INJECTION: STILETTO CONCEPTION OR A STAB IN THE DARK

Yukihiro Terada, S. Nakamura, Junko Morita, Calvin R. Simerly et autres

To describe the importance of molecular and cellular analyses in intracytoplasmic sperm injection (ICSI) the authors review the literature on biological challenges in ICSI and associated techniques. Several matters can be proposed in molecular and cellular challenges in ICSI for safety and …
