SCREENING OF IN VITRO-PRODUCED CATTLE EMBRYOS TO ASSESS INCIDENCE AND CHARACTERISTICS OF UNBALANCED CHROMOSOMAL ABERRATIONS

Screening of in vitro-produced cattle embryos to assess incidence and characteristics of unbalanced chromosomal aberrations

In cattle, pregnancy rates of in vitro-produced embryos are lower than those of in vivo-produced embryos.One of the reasons may be the increase in chromosomal aberrations due to in vitro maturation and fertilization of the oocyte.Currently, embryo transfer is commonly applied in nucleus cattle breeding programs, and the embryos are genotyped for ge

Temperature and medium structurization effect on spontaneous evolution of domains and bubbles in magnetic nanostructures

Spontaneous evolutions of domains in magnetic nanowires and of magnetic bubbles in open ferromagnetic nanolayers are investigated using micromagnetic simulations.We compare temperature dependent dynamics of domain wall (DW) systems in Permalloy (Py) nanowires and systems of chiral DWs in ultra-thin nanowires with perpendicular magnetic anisotropy (
