Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Ecology
  • Enzyme

His primary areas of study are Oocyte, Blastocyst, Cryopreservation, Human fertilization and Embryo. In general Oocyte study, his work on In vitro maturation often relates to the realm of Oxygen tension, thereby connecting several areas of interest. Takashi Nagai has included themes like In vitro and Vitrification in his Blastocyst study.

His work carried out in the field of Human fertilization brings together such families of science as Sperm and Polyspermy. Takashi Nagai has researched Embryo in several fields, including Oxidative stress, Biochemistry, Oviduct, Glutathione and Immunology. As a part of the same scientific study, Takashi Nagai usually deals with the In vitro fertilisation, concentrating on Embryo transfer and frequently concerns with Zygote.

His most cited work include:

  • Successful Piglet Production after Transfer of Blastocysts Produced by a Modified In Vitro System (292 citations)
  • Cryopreservation and ensuing in vitro fertilization ability of boar spermatozoa from epididymides stored at 4°C (170 citations)
  • High survival rate of bovine oocytes matured in vitro following vitrification. (158 citations)

What are the main themes of his work throughout his whole career to date?

Takashi Nagai spends much of his time researching Blastocyst, Oocyte, Embryo, Human fertilization and In vitro. The various areas that Takashi Nagai examines in his Blastocyst study include In vitro fertilisation, Vitrification, Immunology and Cryopreservation. He is interested in In vitro maturation, which is a branch of Oocyte.

His In vitro maturation research is multidisciplinary, incorporating perspectives in Follicular phase and Germinal vesicle. His study in Embryo is interdisciplinary in nature, drawing from both Molecular biology and Biochemistry. His Human fertilization research includes elements of Sperm and Polyspermy.

He most often published in these fields:

  • Blastocyst (38.62%)
  • Oocyte (27.51%)
  • Embryo (26.98%)

What were the highlights of his more recent work (between 2013-2020)?

  • Oocyte (27.51%)
  • Blastocyst (38.62%)
  • Pesticide (6.35%)

In recent papers he was focusing on the following fields of study:

His main research concerns Oocyte, Blastocyst, Pesticide, Human fertilization and Cryopreservation. Particularly relevant to In vitro maturation is his body of work in Oocyte. His Blastocyst study contributes to a more complete understanding of Embryo.

In his work, Tributary, Pesticide residue, Passive sampling and Sampling is strongly intertwined with Environmental chemistry, which is a subfield of Pesticide. As part of the same scientific family, Takashi Nagai usually focuses on Human fertilization, concentrating on Sperm and intersecting with Artificial insemination and Semen. His study looks at the relationship between Cryopreservation and fields such as Vitrification, as well as how they intersect with chemical problems.

Between 2013 and 2020, his most popular works were:

  • Generation of Live Piglets from Cryopreserved Oocytes for the First Time Using a Defined System for In Vitro Embryo Production (43 citations)
  • The effect of binary mixtures of zinc, copper, cadmium, and nickel on the growth of the freshwater diatom Navicula pelliculosa and comparison with mixture toxicity model predictions (23 citations)
  • Leukemia inhibitory factor promotes porcine oocyte maturation and is accompanied by activation of signal transducer and activator of transcription 3. (22 citations)

In his most recent research, the most cited papers focused on:

  • Gene
  • Ecology
  • Enzyme

Takashi Nagai mainly focuses on Oocyte, Environmental chemistry, Pesticide, Blastocyst and Cryopreservation. The Environmental chemistry study combines topics in areas such as Ecology and Aquatic organisms. Takashi Nagai combines subjects such as In vitro fertilisation, In vitro maturation and Human fertilization with his study of Blastocyst.

His work deals with themes such as Sperm, Embryo transfer, Embryo and In Vitro Oocyte Maturation Techniques, which intersect with Human fertilization. His Cryopreservation study incorporates themes from Vitrification and Germinal vesicle. His Vitrification research is multidisciplinary, incorporating elements of Immunology, Reproductive technology, Embryogenesis, Gamete and Cryoprotectant.
