| antigenic and structural relationships between avian paramyxoviruses isolated from ducks in hong kong and mississippi, u.s.a. | representative isolates of the paramyxoviruses duck/hong kong/75 and duck/mississippi/75 were shown to be serologically closely related by haemagglutination and neuraminidase inhibition tests. the structural polypeptides of these viruses were also shown to be similar. for each of the isolates tested, polyacrylamide gel electrophoresis in the presence of sds revealed a similar polypeptide pattern consisting, under reducing conditions, of seven polypeptides with apparent mol. wt. ranging from 4600 ... | 1979 | 93619 |
| expression of feline xenotropic rna tumor virus in hybrids between permissive human and non-permissive mouse cells. | somatic cell hybrids were generated by fusing human (a549) cells, cloned after infection with the feline xenotropic ccc virus, to mouse (3t3) cells which are non-permissive for this virus. hybrid clones were found to be capable of expressing infectious virus. ccc virus expression, however, was regulated in the hybrid cells in such a way that 20-200 times less virus was released into the culture fluid than by the human parental line. thus human permissiveness for this virus is co-expressed with m ... | 1979 | 94594 |
| interaction of phenosafranine with nucleic acids and model polyphosphates. iii. heterogeneity in phenosafranine interactions with dna base pairs. | fluorescence and circular dichroism spectral measurements, thermal denaturation studies and binding competition experiments with netropsin and actinomycin d were carried out in systems containing phenosafranine bound to dna's differing in base composition. the investigated properties exhibit a heterogeneity related to the content of a.t and g.c pairs in dna and to the nature of phenosafranine binding modes. at low level of saturation of binding sites (r less than 0.1) phenosafranine does not sho ... | 1979 | 106900 |

| fluorescence of human liver alanine aminopeptidase. | fluorescence of human liver alanine aminopeptidase has been attributed to tryptophan fluorescence. the fluorescence maximum is at 330 nm, 20 nm lower than that for free tryptophan, suggesting that most of the enzyme tryptophans are in a nonpolar environment and are shielded from solvent. quenching of enzyme fluorescence by iodide, pyridine, and n-methyl nicotinamide also demonstrates that enzyme tryptophan residues are largely buried and inaccessible to solvent. those accessible are in negativel ... | 1977 | 143669 |

| ketone bodies are selectively used by individual brain regions. | close study of 3-hydroxybutyrate uptake by brain suggests that its metabolism is limited by permeability. furthermore, the permeability characteristics vary from region to region; areas known to have no blood-brain barrier show the highest rate of utilization. the results imply that rather than substitute fuels, ketone bodies should be considered supplements which partially supply specific areas but are incapable of supporting the entire energy requirement of all brain regions. | 1979 | 451608 |
| contractile properties of extraocular muscle in siamese cat. | siamese cats are albinos with poor visual resolution and severely impaired binocular vision. eey muscle phyiology was studied in siamese cats as a part of a more extensive project on eye muscle properties in cats with deficient binocular vision. isometric contractions of the inferior oblique muscle were recorded in response to single and repetitive muscle nerve stimulation. speed of contraction, measured as twitch contraction time, fusion frequency and rate of tetanic tension rise, was lower in ... | 1979 | 545999 |

| kaposi's sarcoma among aids patients: transmissible venereal tumour by cell engraftment? | the epidemiologic findings of kaposi's sarcoma (ks) among patients with the acquired immunodeficiency syndrome (aids) suggest that human immunodeficiency virus (hiv) infection is insufficient for the development of ks. it was speculated that another sexually transmitted infection is responsible for the markedly increased incidence of ks among patients who acquired hiv infection through sexual intercourse. however, no such contributing infectious agent was consistently identified. the canine tran ... | 1991 | 1865840 |
| suppression of human colorectal carcinoma cell growth by wild-type p53. | mutations of the p53 gene occur commonly in colorectal carcinomas and the wild-type p53 allele is often concomitantly deleted. these findings suggest that the wild-type gene may act as a suppressor of colorectal carcinoma cell growth. to test this hypothesis, wild-type or mutant human p53 genes were transfected into human colorectal carcinoma cell lines. cells transfected with the wild-type gene formed colonies five- to tenfold less efficiently than those transfected with a mutant p53 gene. in t ... | 1990 | 2144057 |
| pancreatic polypeptide inhibits pancreatic enzyme secretion via a cholinergic pathway. | in rat pancreatic slices, rat pancreatic polypeptide (pp) or c-terminal hexapeptide of pp [pp-(31-36)] inhibited potassium-stimulated amylase release in a dose-dependent manner. the inhibition was unaffected by addition of hexamethonium but blocked by atropine. in contrast, pp(31-36) did not have any effect on acetylcholine- or cholecystokinin octapeptide-stimulated amylase release. in addition, when pancreatic slices were incubated with [3h] choline, pp(31-36) inhibited the potassium-evoked rel ... | 1987 | 2446510 |
