initiation of swimming activity by trigger neurons in the leech subesophageal ganglion. iii. sensory inputs to tr1 and tr2. | in papers i and ii of this series, we described two pairs of interneurons, tr1 and tr2, in the leech subesophageal ganglion which can trigger swimming activity in the isolated central nervous system (cns). in this paper, we describe sensory inputs to these trigger neurons from previously identified mechanosensory neurons. we found that: weak mechanical stimulation (stroking) of a body wall flap attached to a segmental ganglion in an otherwise isolated cns excites the contralateral tr1 slightly. ... | 2010 | 3023604 |
mutations linked to the pro alpha 2(i) collagen gene are responsible for several cases of osteogenesis imperfecta type i. | we have analysed six south african families with osteogenesis imperfecta type i using three dna polymorphisms associated with the pro alpha 2(i) collagen gene. in four of these families linkage of the pro alpha 2(i) gene and the osteogenesis imperfecta phenotype was suggested, whereas in the remaining two families there was a lack of linkage. no distinct correlation could be made between the phenotypic features of the families studied and linkage or lack of linkage to the pro alpha 2(i) gene. tw ... | 2010 | 3023615 |
structure of replicating simian virus 40 minichromosomes. the replication fork, core histone segregation and terminal structures. | the structure of replicating simian virus 40 (sv40) minichromosomes was studied by dna crosslinking with trimethyl-psoralen. the procedure was used both in vitro with extracted sv40 minichromosomes as well as in vivo with sv40-infected cells. both procedures gave essentially the same results. mature sv40 minichromosomes are estimated to contain about 27 nucleosomes (error +/- 2), except for those molecules with a nucleosome-free gap, which are interpreted to contain 25 nucleosomes (error +/- 2). ... | 1986 | 3023620 |
relative activities of 5'-nucleotidase and adenosine deaminase in atrial and ventricular myocardium--the enzyme paradox. | the 5'-nucleotidase and adenosine deaminase activities were determined for tissue extracts of up to 10 defined regions of the normal dog heart. the specific activity of 5'-nucleotidase was very significantly higher in atrial than in ventricular myocardium (4 x) and was also higher in right than in left sites of the heart (2 x). the reason for the markedly higher specific activity in atrial muscle is not clear and appears paradoxical relative to adenine nucleotide content and pattern of atp decay ... | 1986 | 3025011 |
