In mouse AA amyloid, residues 50–64 are exposed, while residues 65–86 adopt a U-shaped structure that is, except for residues 66–72, largely exposed and in loose contact with the other protomer. A non-conserved sequence insertion at position 86 of the precursor protein sequence sets apar...
The administration of testosterone to castrated male rats increased the rate of gap junctions between folliculo-stellate cells; however, progesterone and 17beta-estradiol did not affect the formation of gap junctions. The administration of progesterone to ovariectomized female rats increased the rate of...
The pituitary anterior lobes of male rats castrated at the age of 45 days were investigated histologically and histometrically at various time-intervals of between 10 and 300 days after operation. The total number of the cells of the glands was counted on the serial sections made of the glands...
