La distribuzione dell'attività proteasica nella blastula e nella giovane gastrula diDiscoglossus pictus

1956

Summary Protease activity has been measured in the animal and vegetal half of the blastula and in the dorsal and ventral regions of the early gastrula of Discoglossus pictus. A higher protease activity was found in the dorsal region of the early gastrula, where presumptive chordamesoderm and presumptive neuroectoderm are localized.

Occurrence and regional distribution of calcareous concretions in the rat pineal gland.

1978

Serial sections of 90 Sprague-Dawley rat brains with the pineal in situ were scanned to determine the occurrence and regional distribution of calcareous concretions within the pineal gland and its surrounding leptomeningeal tissue. In 90% of the cases examined concretions were found in varying number and appearance, predominantly lying in the dorsal region of the pineal gland and in the distal portion of the pineal stalk. Discussing the hypothesis advanced by Lukaszyk and Reiter (1975) that the origin of pineal concretions may be related to a neurosecretory process involving a pineal carrier protein, called neuroepiphysin, it is thought that, in view of the intra- and extra-pineal occurrenc…
