#35 : Tail-First Sperm Injection Significantly Improved the Fertilization Rates More Than the Head-First Sperm Injection Regardless of the Elasticity of the Oocyte Membrane Following Piezo-ICSI

Autor: Kenichiro Hiraoka, Nozomi Uchida, Hayata Nakajo, Moe Sato, Saki Ishikawa, Toshio Sujino, Akira Komiya, Yuko Takayanagi, Yurie Nako, Makiko Tajima, Kiyotaka Kawai

Publikováno v: Fertility & Reproduction, Vol 05, Iss 04, Pp 409-410 (2023)

Background and Aims: Little information is available for investigating the effect of the direction of sperm injected into the cytoplasm on clinical results for human oocytes following intracytoplasmic sperm injection (ICSI). This study aimed to exami

Publikováno v: Clinical and Experimental Obstetrics & Gynecology, Vol 50, Iss 4, p 80 (2023)

Background: Empty follicle syndrome (EFS) is a rare complication in which no oocytes are retrieved in oocyte pick-up (OPU) despite adequate controlled ovarian hyperstimulation (COH). Various studies and systematic reviews have reported that EFS is ma

STRUCTURE OF THE 5' UPSTREAM REGION AND THE REGULATION OF THE RPOS GENE OF ESCHERICHIA-COLI

Autor: Hideo Takahashi, Yuko Takayanagi, Kan Tanaka

Publikováno v: Molecular & General Genetics. 243(No. 5):525-531

The nucleotide sequence of the 5' upstream region of the Escherichia coli rpoS gene was determined and analyzed. At least four promoters responsible for rpoS transcription were identified, and designated P1, P2, P3 and P4, P1 being furthest from the

Stationary phase-specific expression of the fic gene in Escherichia coli K-12 is controlled by the rpoS gene product (sigma 38)

Autor: Takahiro Nakayama, Manjiro Noda, Hideo Takahashi, Yuko Takayanagi, Ryutaro Utsumi, Kan Tanaka, Makoto Kawamukai, Shie Kusafuka

Publikováno v: FEMS microbiology letters. 113(3)

The fic gene, near pabA located at 75 min of the Escherichia coli chromosome, was previously identified as the regulatory factor of cell division. In this paper we have examined how fic gene expression is controlled during the growth cycle using a fi

Heterogeneity of the principal sigma factor in Escherichia coli: the rpoS gene product, sigma 38, is a second principal sigma factor of RNA polymerase in stationary-phase Escherichia coli

Autor: Yuko Takayanagi, Nobuyuki Fujita, Akira Ishihama, Kan Tanaka, Hideo Takahashi

The rpoS gene of Escherichia coli encodes a putative RNA polymerase sigma factor that is considered to be the central regulator of gene expression in stationary phase. The gene product (sigma 38) was overproduced using the cloned rpoS gene and purifi
