In the experiments, the researchers removed the nuclei of mature oocytes from healthy young women who had previously donated eggs for successful infertility treatments. The SCNT technique was then used ...Akahoshi Prechop (temporal approach)
Description:... Straight shafts, cross action. Round handle. Divides nucleus for phacoemulsification. Nuclear division is attained without grooving. nuclei of any hardness can be pre-chopped with pre-chop forceps and nucleus sustainer. Phaco of pre-chopped nuclear fragments is rapid. Risk of rupturing ...UCSD researchers make first direct observations of biological particles in high-altitude ice clouds
