| x-linked mental retardation: transmission of the trait by an apparently unaffected male. | a pedigree is presented in which an apparently unaffected man transmitted the gene for x-linked mental retardation to at least four of his 12 daughters. none of his 12 sons was mentally retarded. these findings may be explained by a somatic mutation and germinal mosaicism in the father or by a half chromatid mutation in maternal gametes. | 1978 | 263439 |
| cytotoxic activity of aeromonas hydrophila. | most strains of aeromonas hydrophila tested demonstrated cytotoxic activity on several tissue-cultured cell lines. the cytotoxin is heat-labile, non-dialyzable, and immunologically distinct from that of shigella dysenteriae and clostridium perfringens. none of the aeromonas isolates was found to be enterotoxigenic by either tissue culture or rabbit ileal loop assays. | 1978 | 711344 |

| major histocompatibility complex products restrict the adherence of cytolytic t lymphocytes to minor histocompatibility antigens or to trinitrophenyl determinants on schistosomula of schistosoma mansoni. | we have previously shown that schistosomula passaged through mice acquire histocompatibility (h) antigens that can be recognized either by alloantibody or by alloreactive cytolytic t lymphocytes (ctl). the latter specifically adhere to but fail to damage the parasite. in this paper we describe the use of trinitrophenyl (tnp)-labeled schistosomula to show that the adherence of ctl with specificity for tnp-modified syngeneic cells is restricted by the major histocompatibility complex (mhc) in a fa ... | 1979 | 88051 |
| antigenic determinants of influenza virus hemagglutinin. ii. antigenic reactivity of the isolated n-terminal cyanogen bromide peptide of a/memphis/72 hemagglutinin heavy chain. | gel filtration of a cyanogen bromide digest of pure intact hemagglutinin from a/memphis/102/72 influenza virus allowed the isolation of a variety of fragments. one of these fragments consists of three cyanogen bromide peptides (cnl and cn3 from ha1, and cnl from ha2) which remain linked together by disulphide bonds. this fragment was found to be antigenically active, as it was able to form antigen-antibody complexes (detected by affinity chromatography of radioiodinated peptide-igg mixtures on p ... | 1979 | 88123 |

| the intra-nucleolar localization of amplified rdna in xenopus laevis oocytes. | a fluorescent feulgen-stain was adapted in order to demonstrate dna-containing structures inside the amplified nucleoli of xenopus laevis. at all stages of oogenesis this method reveals granules or complex structures of dna in each nucleolus. the micronucleoli which do not stain with this method and which do not reveal an internal structure in low molarity saline, unlike real nucleoli are considered as nucleolus-like bodies. the dna-containing structures in the nucleoli can be composed of one or ... | 1979 | 90588 |
| characterization of a type-c virus produced by co-cultures of human leukemic bone-marrow and fetal canine thymus cells. | the putative human helper virus ska-21/a204v, isolated by nooter et al. in 1977 from human leukemic bone-marrow cells following co-culture with normal fetal canine thymus cells, cf2th, has been characterized with respect to its major viral core protein, reverse transcriptase, and nucleic acid sequences. the results of these analyses show that this virus is not distinguishable from the woolly monkey type-c virus, ssav-1, by the techniques employed. | 1979 | 90662 |
| latex fetuin spheres as probes for influenza virus neuraminidase in productively and abortively infected cells. | fetuin bound latex spheres do not adhere to the membranes of non-infected cells but adhere to those of cells productively infected by fowl plague virus (fpv dobson strain). in contrast, asialo fetuin spheres do not attach to the membranes of productively infected cells. moreover latex fetuin spheres incubated with extracts of productively infected cells and extensively washed are specifically enriched in neuraminidase activity without any trace of haemagglutinin. these observations suggest that ... | 1979 | 91354 |
| connectivity of the auditory forebrain nuclei in the guinea fowl (numida meleagris). | injection of tritiated leucine and proline into the nucleus ovoidalis of the guinea fowl (numida meleagris) produces terminal labeling in the palaeostriatum and in three adjacent zones (field l1-l3) of the auditory neostriatum (an). l2, situated between l1 and l3, receives the main input and corresponds to the former field l of rose. these neuroanatomically defined zones of the auditory neostriatum are also characterized by differing properties of their neurons. injection of radioactive material ... | 1979 | 91442 |

| shigellosis and escherichia coli diarrhea: relative importance of invasive and toxigenic mechanisms. | shigellae and dysentery-like escherichia coli must invade the epithelium of the colon to cause disease which can present as dysentery, diarrhea, or both. this paper addresses the possible role of a shigella dysenteriae-like (shiga-like) toxin in the pathogenesis of shigellosis and e. coli diarrheal diseases. the possibility for such a role is suggested by the following observations: 1) diarrhea, considered to be a result of secretion of water by the small bowel, is frequently observed in shigell ... | 1979 | 104615 |
| [on the antimicrobial activity of propolis and propolis constituents (author's transl)]. | after a survey of the literature on the antimicrobial activity of the bee product propolis, the authors discuss their own findings as compared to the chemotherapeutical agents streptomycin, oxytetracycline, chloramphenicol, nystatin, griseofulvin and sulphamerazine. according to the results obtained by testing 25 isolated constituents on bacillus subtilis, staphylococcus aureus, candida albicans and trichophyton mentagrophytes, the antimicrobial properties of this mixture of natural substances a ... | 1979 | 108687 |
| patterns of virus-immune t-cell responsiveness. comparison of (h-2k x h-2b) leads to h-2b radiation chimeras and negatively selected h-2b lymphocytes. | negatively selected h-2k(b)d(b) tdl can be induced to respond strongly to vaccinia virus presented in the context of both h-2k(k) and h-2d(b) when stimulated in irradiated h-2k(k)d(b) recipients. addition of excess (h- 2k(k)d(b) x h-2k(b)d(b))f1 tdl, which are low responders to h-2d(b)-vaccinia virus, does not obviously suppress the reactivity pattern of the h-2k(b)d(b) t cells. however, lymphocytes from chimeras made by reconstituting h- 2k(b)d(b) mice with (h-2k(k)d(k) x h-2k(b)d(b))f(l) bone ... | 1979 | 115959 |

| mitomycin c stimulates production of a toxin in shigella species that causes morphological changes in chinese hamster ovary cells. | shigella dysenteriae produced a toxin that caused morphological changes in chinese hamster ovary cells which was different from the neurotoxin (y. takeda, k. okamoto, and t. miwatani, infect. immun. 18:546--548, 1977). it was found that the toxin was produced not only by s. dysenteriae but also by s. flexneri, s. boydii, and s. sonnei. the production of the toxin was stimulated by the addition of 1 microgram of mitomycin c per ml to the culture in the early logarithmic growth phase. | 1979 | 370009 |
| characteristics of lipid a-protein complex from endotoxin of shigella dysenteriae type 1 (s and r strains). | mild acetic acid hydrolysis of endotoxin (lipopolysaccharide-protein complex) of shigella dysenteriae type 1 (s and r forms) yielded a lipid a-protein complex that consisted of amino acids, fatty acids, and sugar and, in terms of chemical composition, displayed no marked differences between the s and r forms. its protein portion (53 to 56%) consisted of at least 16 amino acids. in the fatty acid portion (14 to 18%), myristic, 3-hydroxymyristic, palmitic, and stearic acids accounted for 50%. the ... | 1979 | 370018 |
| construction of plasmid cloning vehicles that promote gene expression from the bacteriophage lambda pl promoter. | two multiple-copy, cole1-type, plasmid cloning vehicles, phub2 and phub4, have been constructed that carry four different single restriction sites down-stream from the phage lambda promoter pl. the promoting activity of pl is switched off at low temperature in the presence of a cits gene that specifies a temperature-sensitive repressor but could be activated by heat induction. cits was located either on the host chromosome, or on a second plasmid prk248 that is compatible with the cloning vehicl ... | 1979 | 372049 |
