Glasses formed from nano- and microparticles form a fascinating testing ground to explore and understand the origins of vitrification. For atomic and molecular glasses, a wide range of fragilities have been observed; in colloidal systems, these effects can be emulated by adjusting the particle softness. The colloidal glass transition can range from a superexponential, fragile increase in viscos...

The in vivo survival of hereditary spherocytes has been investigated with the (51)Cr red cell survival technique. Spherocytes invariably showed a shorter survival in a normal recipient than in the donor's own circulation. Moreover transfusion of spherocytes from a mother to her son, both with hereditary spherocytosis, showed that "foreign" spherocytes have a shorter survival than the "self" sph...

BACKGROUND Diabetes has been associated with several complications occasioned by oxidative stress. Thus, in treatment of the condition, these complications must also be taken into consideration. This study evaluates the effect of Cnidoscolus aconitifolius complications of diabetes induced by alloxan, on haematology and sperm morphometry using the Wistar rats. METHODS Diabetes was induced in 2...

Previous work has indicated that inbred mouse strains C57BL/6 and DBA/2 produce red cells differing in their sensitivity to osmotic lysis and that the trait is under multigene control. A recombinant inbred strain (BXD-31), produced from C57BL/6 and DBA/2, has red cells manifesting resistance to osmotic lysis far greater than that of either progenitor. We demonstrate here that the fragility diff...

BACKGROUND Difficulties with the direct antiglobulin test (DAT) and its apparent lack of sensitivity and specificity for immune-mediated hemolytic anemia (IMHA) in dogs have raised skepticism regarding its diagnostic value. OBJECTIVE To compare different DATs and other hematologic parameters in dogs. ANIMALS Anticoagulated blood samples from 59 nonanemic and 46 anemic dogs (± IMHA) from a r...
