Rita Kakkart enucleate where rendered nonviable by treatment with mitomycin C. Whole cells were poisoned with a 99% lethal dose of the sulfhydryl reagent iodoacetate. The washed cells were then mixed with the anucleate cytoplasms, fused with inactivated Sendai virus, and planted in rotenone for 20 hours. Where外观 发表于 2025-3-24 04:43:31

Arijit Basu,Barij Nayan Sinhaf haploid cell cultures. In order to exploit the obvious advantages for genetic experimentation of cell populations with a single chromosome set, we have for some time been studying cell lines initiated from haploid as well as diploid frog embryos (1). Since our initial publication in 1962, we have连系 发表于 2025-3-24 20:00:25

In view of the central role played by the circulation in meeting the oxygen demands of the tissues, it is not surprising to find that the cardiocirculatory system has been extensively remodelled in icefish. These adaptations in碎片 发表于 2025-3-24 23:35:40
Dimitra Hadjipavlou-Litina,Eleni Pontikitemperature are less than 0.2 °C close to the permanent ice shelf (Littlepage 1965), and only 2.5 °C in the northern Antarctic (Everson 1970). There is evidence that these stenothermal conditions have existed relatively unchanged for several million years (Kennett 1977). Antarctic fish have therefor
