A clinico-morphological study of ataxia-teleangiectasia permits to establish the depth and distribution of lesions. Morphological findings indicate to lesions mainly in the extrapyramidal system, cerebellum, subcortical structures and in the stem structures and spinal cord. Besides, there were changes in the hemispheres in the form of cell atrophy,(More)
A sudden increase of temperature of surrounding medium, even in the sublethal range, induced in Amoeba proteus (strain War) and Amoeba borockensis the synthesis of a new class of proteins, which might be classified as the heat shock proteins (hsp). The new pattern of protein synthesis, determined by incorporation of (35)S-methionine, was detectable within(More)
The enucleated specimens of Amoeba proteus, the anucleate fragments, and the polynucleate individuals which all are capable of cortical contraction but not of locomotion, may be reactivated by the light-shade difference established across their body. Individual cells or fragments migrate toward the shade. The motory polarity and coordinated movement(More)
