[radioimmunological aspects of neuropeptides].	immunological aspects of neurosecretory peptides are relevant to antibody generation, labelling of peptides for radioimmunoassays and in particular the metabolism of neuropeptides. antibodies were generally produced by adsorption or polymerization (using different approaches and various coupling agents) of peptides with intrinsic antigenic molecules preceding their administration to recepient animals (rats, guinea pigs, rabbits and sheep) with adjuvants. antibodies were also obtained by injectin ...	1978	96897
[formation of cutaneous nerve trunks in the chick. ultrastructural and quantitative analysis].	in chick skin structuration of nervous trunks takes place at 14-15 days of incubation, at the time of formation of the adult pattern of cutaneous innervation. at this same stage, myelogenesis begins, but develops mainly after hatching: only 4% of axons are myelinated at hatching, 40% in 6-week old chickens and 60% in adults. this "critical" stage (14-15 days of incubation) apparently corresponds to the stabilization of cutaneous nerve supply.	1978	96985
[nature of the mutations that determine the ability of bacillus subtilis a-50 to sporulate at high glucose concentrations in the medium].	the ability of bacillus subtilis a-50 to sporulate in the medium containing high glucose concentrations is caused by at least two mutation types: pts mutations and cat (or tgl) mutations, both of them affecting differently the level of alkaline proteinase synthesis. the decrease of the level of enzyme activity in the case of pts mutation (glur3 mutant) occurs at the expense of glucose transport disturbance. the mutation cat (tgl) (mutant glur5) causes the increase in enzyme synthesis at the expe ...	1978	97172
biosynthesis of delta-aminolevulinic acid by blue-green algae (cyanobacteria).	when levulinic acid, a competitive inhibitor of delta-aminolevulinic acid dehydratase, was added to growing cultures of blue-green algae (cyanobacteria), delta-aminolevulinic acid was excreted into the medium and cell growth was inhibited.	1978	97274

a developmental model for studying choline acetyltransferase transport in chick motoneurons.	the proximodistal axonal transport of choline acetyltransferase (chac) has been studied in the chick sciatic nerve in the absence of any experimental manipulation. the phenomenon utilized by us is a physiological transient fall in the activity of chac. this fall occurs in most areas of the chick central nervous system after hatching, and moves toward the periphery along the nerves. having ruled out the presence of transient inhibitors, the movement of the fall towards skeletal muscles has been c ...	1979	94010
alien h-2 allospecificities in murine chemically-induced tumors.	sera from c3h/heha mice immunized with syngeneic methylcholanthrene-induced sarcoma react with allogeneic thymus, lymphoma and leukemia cells. the presence on leukemia and lymphoma cells of h-2 specificities expressed on normal cells of other h-2 haplotypes from the one in which the tumor originates is described. it was observed that the reaction of antisera to h-2 specificities with lymphoma cells was blocked by anti-mca sarcoma sera. the cross-reactivity between mc sarcomas, thymus, leukemia a ...	1979	94037
