164. Hybridization in Highly Strained Small Ring Hydrocarbons. I. Tricyclo- and Tetracyclopropylidene

Author

M. Randić and L. Jakab

Abstract

The hybridization in tricyclopropylidene and tetracyclopropylidene has been calculated by the method of maximum overlap. The results show that the hybrids describing the central ring have more s character than those in cyclopropane and cyclobutane: sp3·02 and sp3·31 as compared to sp3·86 and sp3·47 respectively. Consequently the central bonds in the two molecules investigated . are stabilized by the cyclopropyl substitutions. An interesting comparison between the maximum overlap hybridization and hybridization based on more elaborated calculations is made.

167. Role of mucoid substances of the aorta in the deposition of lipids

Abstract

THE mechanism of deposition of lipids in the vessel-wall seen from the point of view of the pathogenesis of atherosclerosis represents the central problem of the latter. In agreement with numerous data1–4, our previous investigations5 proved that in the morphogenesis of both human and experimental atherosclerosis the deposition of lipid substances in the aorta is preceded by an increase of metachromatically stainable mucoid substance.

175. Hybridization in Highly Strained Small Ring Hydrocarbons. II. Methylene Biscyclopropylidene and Dimethylene Biscyclopropylidenes

Author

M. Randić and L. Jakab

Abstract

The hybridization in methylene biscyclopropylidene, 1,1'-dimethylene biscyclopropylidene, and 1,2-dimethylene biscyclopropylidene is considered by applying the method of maximum overlap. The results show variations in hybrids describing exocyclic double bonds: for ring carbons from sp~.ss to sp2-85, and for off-ring carbons from sp1-10 to sp1-41, depending on the immediate surounding. Bond overlaps for C=C consequently vary somewhat, the largest bond overlap being of the central C=C bond connecting two three membered rings. The results of the maximum overlap calculations are compared with available experimental data.

Abstract

The wideband planar acoustooptic (AO) Bragg deflector serves as a key element in today's signal processing and communication systems, especially with respect to the AO modulators, the analog light beam scanners, the spectral analysers, convolvers and correlators of wideband RF signals [1].

Abstract

THE acid mucopolysaccharides (MPS) as macro-anions form complexes with proteins and thus they change the isoelectric point of the latter. Based on this property some MPS's are able to inhibit or activate many enzyme systems1.

200. Morphogenetic Plasticity of Neuronal Elements in Cerebellar Glomeruli during Deafferentation-Induced Synaptic Reorganization

Author

Hámori, József, L. Jakab, Robert, and Takács, József

Abstract

Reorganization of the cerebellar glomerulus, the main synaptic complex within the granule cell layer, was investigated using quantitative morphological techniques. All afferents to the cerebellar cortex, including mossy-fibers, were surgically destroyed by undercutting the cerebellar vermis. Fifteen days after the operation, which resulted in the removal of the main excitatory afferent to the glomerulus, a significant reorganization of the whole synaptic complex was observed, whereas the structural integrity of the glomerulus was remarkably well preserved. This was indicated by the observation that the number of granule cell dendrites (≈50 per glomerulus), as well as the number of dendritic digits (≈210 per glomerulus) bearing most of the ≈230 synaptic junctions per glomerulus, did not change significantly after mossy-fiber degeneration. The total number of synapses in the reorganized glomerulus did not change either, despite the disappearance of two-thirds of (excitatory) synaptic junctions caused by mossy-fiber degeneration. In the reorganized glomeruli, however, the inhibitory, GABA-containing Golgi axonal varicosities became the dominant synaptic type—about four-fifths (≈200) of all synapses within the glomerulus—whereas the dendritic synapses between the granule cells represented only one-fifth of all synaptic junctions. The quantitative data of the reorganized cerebellar glomerulus demonstrate both a remarkable constancy and a plasticity of he excitatory granule cells and inhibitory Golgi neurons building up this synaptic complex. constancy (the preservation of certain specific structural features) is represented by an eventually unchanged number of dendrites and synaptic junctions within the deafferented lomerulus. Such constancy was made possible, however, by the morphogenetic plasticity of both nerve-cell types to produce new, dendrodendritic and axo-dendritic synapses to compensate for the loss of mossy-fiber synapses.
