A filovirus, serologically related to Ebola virus, was detected by "post-embedment" immunoelectron microscopical examination of MA-104 cells. These had been infected by inoculation with serum samples obtained during the 1989 epizootic in cynomolgus monkeys (Macaca fascicularis), imported from the Philippines and maintained at Reston, Virginia, USA, a primate holding facility.

A spicular arrangement of amyloid on the epithelial aspect of the glomerular basement membrane has been seen to a variable degree in silver-stained sections of renal biopsies in eight of 38 patients with amyloidosis. Electron microscopical examination revealed a spectrum of appearances of the amyloid fibrils which would account for this finding. Only two of these eight patients had amyloidosis ...

1. A method for the separation of chromatin threads from the resting nucleus of leukemic cells has been described. 2. The isolation of the chromatin strands was accomplished by purely mechanical means, and the separation, including extraction and purification in the centrifuge, required only about 1 hour. 3. Evidence is presented to show that the chromatin strands are morphologically related to...

In the last decades, the incidence of skin cancer is in continuous growth, but the mortality remains at the same level thanks to the new imaging diagnosis methods and surgical treatment.
