the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Envelope of mouse mammary tumor virus studied by freeze-etching and freeze-fracture techniques.
As part of a study of the cell surface changes associated with the production of murine mammary tumor virus, the structure of the envelope of this virus has been examined by using freeze-fracture techniques. Both fracture and deep-etch surfaces were examined. The fracture faces contain 10-nm spheres comparable to those observed on fractured plasma membranes, although fewer in number. Surfaces e...
متن کاملFine structure of Cryptococcus neoformans grown in vitro as observed by freeze-etching.
Cryptococcus neoformans grown on culture media was observed by the freeze-etching technique. In the capsule, short fibrils were seen when freezeetched. This organism was unique in the appearance of the cell wall, which showed two strata. The outer one was dense with particles of about 20 nm in diameter, whereas the inner one was sparse in particles. The appearance of the cell membrane of this o...
متن کاملViewed by Freeze-Etching'
The indigenous microflora of soil were released from the soil materials and concentrated without the occurrence of growth by use of a blending-simple centrifugation procedure. The cell concentrate was then frozen-etched and viewed by transmission electron microscopy. Criteria were established for detecting microbial cells among the residual soil debris. The freeze-etching of the soil cell conce...
متن کاملUltrastructural details in germinating sporangiospores of Rhizopus stolonifer and Rhizopus arrhizus.
Electron microscope examination of sporangiospore sections from Rhizopus stolonifer (Ehrenb. ex Fr.) Lind. and R. arrhizus Fischer revealed details on intracellular organization not previously reported. Aldehyde fixation followed by chromeosmium postfixation permitted clear depiction of ribosomes hitherto unrevealed in these cells. Mitochondria were diversiform. Spore wall structures in the two...
