introduction: several supra spinal areas such as rostral ventrolateral medulla (rvlm) area are involved in basic cardiovascular regulation. the kolliker— fuse nucleus (kf) is located in pons and is heavily connected with rvlm. the cardiovascular effect of kf nucleus has been shown and it is suggested that kf is involved in sympathetic vasomotor tone and basic cardiovascular regulation. therefor...

Development of mammals is usually initiated by fertilization of an egg by a sperm. The sperm and the egg have distinct roles to play in launching development of a new generation. The sperm must seek out the egg, fuse with it and deliver its precious haploid nucleus. The egg, on the other hand, must make itself apparent to the sperm and be capable of responding appropriately to its contact. That...

The Kolliker— Fuse nucleus (KF) is located in pons and is heavily connected with RVLM. The cardiovascular effect of KF nucleus has been shown and it is suggested that KF is involved in sympathetic vasomotor tone and basic cardiovascular regulation. Therefor...

We have studied the distribution of neurokinin A-like immunoreactive cell bodies and fibers in the cat brainstem. The densest clusters of perikarya containing the peptide were observed in the periaqueductal gray, inferior colliculus, postpyramidal nucleus of the raphe, medial nucleus of the solitary tract and in the lateral reticular nucleus. By contrast, the interpeduncular nucleus, magnocellu...

We report the first observation of perinatal death attributable to morphological alterations of the parabrachial/Kölliker-Fuse complex. In an infant, born at 41 weeks of gestation with severe signs of asphyxia and dead 20 h after delivery, we observed the presence of rare and immature neurons in the brain stem areas of both lateral and medial parabrachial nuclei and the absence of the character...

Propriobulbar neurons having axonal projections to the Ventral Respiratory Group (VRG) were retrogradely labeled after discrete injections of Fast blue into one of the three physiologically identified subdivisions (Bötzinger Complex, rostral inspiratory and caudal expiratory regions). Neurons that project to these regions were found throughout the rostrocaudal extent of the medulla and the pons...

We have previously reported on the development of explosively formed fuse (EFF) opening switches for use in applications where very long conduction times (lO's or lOG's p.s) are required and where opening times of 1-10 p.s are adequate. In this paper we report on the development of an EFF that allows magnetic flux in the switch to be delivered to the load rather than lost from the circuit. The ...
