Left Anterior Arborization Block Combined with Right Bundle Branch Block in Canine and Primate Hearts
Interruption of anterior fibers of the left bundle branch system together with right bundle branch block was accomplished experimentally in canine and primate hearts. In both species the electrocardiographic effects included a major alteration of the mean electrical axis to a superior and anterior direction. Epicardial excitation was markedly delayed anteriorly, causing widening of the QRS comp...

متن کاملMolecular basis of dendritic arborization.
The pattern of dendritic branching along with the receptor and channel composition and density of synapses regulate the electrical properties of neurons. Abnormalities in dendritic tree development lead to serious dysfunction of neuronal circuits and, consequently, the whole nervous system. Not surprisingly, the complicated and multi-step process of dendritic arbor development is highly regulat...
متن کاملThe protein dendrite arborization and synapse maturation 1 (Dasm-1) is dispensable for dendrite arborization.
The development of a highly branched dendritic tree is essential for the establishment of functional neuronal connections. The evolutionarily conserved immunoglobulin superfamily member, the protein dendrite arborization and synapse maturation 1 (Dasm-1) is thought to play a critical role in dendrite formation of dissociated hippocampal neurons. RNA interference-mediated Dasm-1 knockdown was pr...
متن کاملControl of dendrite arborization by an Ig family member, dendrite arborization and synapse maturation 1 (Dasm1).
Development of both dendrites and axons is important for the formation of neuronal circuits, because dendrites receive information and the axon is responsible for sending signals. In the past decade, extensive studies have revealed many molecules underlying axonal outgrowth and pathfinding. In contrast, much less is known about the molecular mechanisms that control dendrite development. Here we...
