Beatrice Resses in division were followed by phase-contrast and polarization optics. When a kinetochore of a metaphase bivalent was irradiated, the birefringence of the associated kinetochore fiber was lost. Then the bivalent shifted to the pole toward which the other unirradiated kinetochore was oriented. Suc

Beatrice Re) replaced the endogenous pancreas by transplanting insulin-producing tissue encapsulated in a semipermeable but immunoprotective membrane to study the effects of absence of vascularization on the survival of tissues. It took, however, until 1943 before the concept of immunoisolation was established

hat replicate in vertebrates or plants. The viruses have to be propagated in arthropod larvae or in arthropod cells. Baculoviruses have been developed as successful expression vectors for the following reasons: (a) baculoviruses are easy to work with and safe to handle, (b) recombinant baculoviruses

ria is that they contain far fewer protein kinases than eukaryotic cells, making it possible to prepare Cdk and Cyclin components in their unphosphorylated state. This facilitates the study of both positive and negative regulation via phosphorylation. Here we describe methods for purification of Cdk

Beatrice Reity resulting from hyperactivation of EAA ionotropic receptors, new information is beginning to emerge pertaining to other forms of excitatory transmitter neurotoxicity. Surprisingly, some of the new forms are triggered not by hyperactivation but by hypoactivation of EAA receptors. Over the past sev

These early events are accompanied by epithelial to mesenchymal transformation, after which the transformed cells

Upon increasing the positive streaming velocity, the ATPase activity first increases and then decreases. On the contrary, at negative streaming velocities, corresponding to lengthening, the ATPas
