LAMELLAE IN THE SPINDLE OF MITOTIC CELLS OF WALKER 256 CARCINOMA [PDF]

Journal of Cell Biology, 1961
In mitotic cells of Walker 256 carcinoma some four-layered lamellar structures were observed which had the appearance of paired cysternae of the ER. Two inner membranes were regular, smooth surfaced, and closely applied to each other. The two outer membranes were somewhat irregularly placed in relation to the inner pair; they showed attached RNP ...

Delivery and Metabolic Fate of Doxorubicin and Betulin Nanoformulations In Vivo: A Metabolomics Approach [PDF]

Metabolites
Background: Betulins (betulin, betulinic acid and lupeol) demonstrated antitumor and chemopreventive activity but showed low bioavailability due to their self-aggregation in hydrophilic environments.
