Morphological Analysis of Human Embryonic Development Using Time-Lapse Cinematography (2006)

Yasuyuki Mio

The dynamic observation of human gametes and the early stage of embryos is of paramount interest for clarifying the physiological events during the fertilization process. We present our morphological...

Analysis of Physiological Process in Early Stage of Human Embryos after ICSI using Time-lapse Cinematography (2005)

Yumi Adachi, Chie Takeshita, Yuka Wakatsuki, Kyoko Iwata, Yukari Kato, Yukiho Ueno, ...

In order to evaluate the physiological events in early stage of human embryos after intracytoplasmic sperm injection (ICSI), we have developed new embryo culture system on the stage of inverted...

Yumi Adachi, Chie Takeshita, Yuka Wakatsuki, Kyoko Iwata, Yukari Kato, Yukiho Ueno, ...

In order to evaluate the physiological events in early stage of human embryos after intracytoplasmic sperm injection (ICSI), we have developed new embryo culture system on the stage of inverted...

Morphometric and cytogenetic characteristics of testicular germ cells and Sertoli cell secretory function in men with non-mosaic Klinefelter's syndrome (2002)

Yamamoto, Yasuhisa, Sofikitis, Nikolaos, Mio, Yasuyuki, Loutradis, Dimitrios, Kaponis, Apostolos, Miyagawa, Ikuo

BACKGROUND: Klinefelter's syndrome is the most frequent chromosomal abnormality in infertile men. In this study, the chromosomes of round spermatids and spermatogonia/primary spermatocytes from men...

Highly sensitive quantitative telomerase assay of diagnostic testicular biopsy material predicts the presence of haploid spermatogenic cells in therapeutic testicular biopsy in men with Sertoli cell-only syndrome (1999)

Yamamoto, Yasuhisa, Sofikitis, Nikolaos, Mio, Yasuyuki, Miyagawa, Ikuo

The role of a telomerase assay in the recognition of Sertoli cell-only syndrome with testicular foci of haploid cells was evaluated. Men with Sertoli cell-only syndrome (n = 23) were given a...

Endocrinology: Reduced implantation rate associated with a subtle rise in serum progesterone concentration during the follicular phase of cycles stimulated with a combination of a gonadotrophin-releasing hormone agonist and gonadotrophin (1995)

Harada, Tasuku, Yoshida, Souichi, Katagiri, Chieko, Takao, Naruhisa, Ikenari, Takaaki, Toda, Toshiko, ...

Our objective was to assess the effects of subtle increases in serum progesterone concentration (1.0–2.0 ng/ml) on the outcome of in-vitro fertilization (IVF), particularly on the quality of...

Assessment of functional integrity of frozen-thawed mouse embryos by albumin and leucine uptake (1994)

Onohara, Yoshimasa, Harada, Tasuku, Tanikawa, Masahiro, Mio, Yasuyuki, Terakawa, Naoki

To assess the effects of freezing–thawing on metabolic functions of embryos prior to implantation, we measured the uptake of [125I]bovine serum albumin (BSA) and [3H]leucine in 2-cell mouse...
