TL;DR: It is proposed that the basal ganglia are involved directly in the manifestation of RJM in the rat, and microinjection of picrotoxin into the rostral part of the head of the caudate-putamen complex produced rhythmical potentials.

TL;DR: A patient with a superior sagittal sinus thrombosis which occurred during the postpartum period is reported, and coagulation studies revealed persistently decreased antithrombin III (AT III) activity.

TL;DR: It is concluded that the abnormal molecules were unable to align their gamma-chains in an anti-parallel fashion because of inaccessibility of the molecules with a profoundly perturbed conformation near the carboxyl terminal region of the gamma-chain included in the D domain.
Abstract: In an abnormal fibrinogen with gamma-Met-310 to Thr substitution accompanied by an extra oligosaccharide attached to gamma-Asn-308, factor-XIIIa-mediated intermolecular gamma-dimer formation of fibrin was found to be markedly delayed. The delayed gamma-dimer formation was not due to impaired fibrin polymerization because the fibrinogen gamma-chain also failed to be efficiently cross-linked by factor XIIIa. Since fluorescent amine was normally incorporated into the abnormal gamma-chain by factor XIIIa, we conclude that the abnormal molecules were unable to align their gamma-chains in an anti-parallel fashion because of inaccessibility of the molecules with a profoundly perturbed conformation near the carboxyl terminal region of the gamma-chain included in the D domain.
