| nonchromaffin paraganglioma (chemodectoma) of thyroid region. | a case of a paraganglioma located over the thyroid cartilage in the midline is reported. the tumor had all the appearances of a carotid body tumor, but its odd location could not be explained on the basis of previously known areas where paraganglionic tissues have been found. since a paraganglioma has also hitherto been described within the thyroid gland, clinicians and pathologists alike are cautioned that unusually located paragangliomas may be expected in the future. | 2003 | 168958 |
| functional consequences of modifying highly reactive arginyl residues of fructose 1,6-bisphosphatase. loss of monovalent cation activation. | modification of pig kidney fructose 1,6-bisphosphatase with 2,3-butanedione (in the presence of amp) results in the loss of activation of the enzyme by monovalent cations. under these conditions about 8 arginyl residues per mole of enzyme were modified. no other residues were modified. no loss of monovalent cation activation occurs when modification with 2,3-butanedione is carried out in the presence of amp plus the substrate fructose 1,6-bisphosphate and 3.2 less arginyl residues were modified. ... | 1975 | 169892 |
| cell-mediated cytotoxicity to chemically-induced rat tumours. | cell-mediated immune reactions against carcinogen-induced rat tumours were demonstrated by the in vitro microcytotoxicity test. lymph-node cells from syngeneic rats immunized against individual aminoazo-dye-induced hepatomas or 3-methylcholanthrene-induced sarcomas were cytotoxic for cells of the immunizing tumour compared with the effects of normal lymph-node cells. only a low level of cross-reactivity was detectable against target cells derived from otherr tumours. conversely, lymph-node cells ... | 1975 | 170224 |
| catabolite repression of pseudomonas aeruginosa amidase: isolation of promotor mutants. | among mutants of pseudomonas aeruginosa isolated from fluoroacetamide medium were some which synthesized amidase at about 5% of the rate of the parent constitutive strain, pac101. seven fluoroacetamide-resistant mutants with low amidase activity gave rise to secondary mutant strains on succinate+butyramide plates. one appeared to be an 'up-promotor' mutant and synthesized amidase at a high rate. this mutant, pac433, was not stimulated by cyclic-amp and was much less sensitive to catabolite repre ... | 1975 | 170366 |
| mapping rnase t1-resistant oligonucleotides of avian tumor virus rnas: sarcoma-specific oligonucleotides are near the poly(a) end and oligonucleotides common to sarcoma and transformation-defective viruses are at the poly(a) end. | the large rnase t1-resistant oligonucleotides of the nondefective (nd) rous sarcoma virus (rsv): prague rsv of subgroup b (pr-b), pr-c and b77 of subgroup c; of their transformation-defective (td0 deletion mutants: td pr-b, td pr-c, and td b77; and of replication-defective (rd) rsv(-) were completely or partially mapped on the 30 to 40s viral rnas. the location of a given oligonucleotide relative to the poly(a) terminus of the viral rnas was directly deduced from the smallest size of the poly(a) ... | 1975 | 170411 |

| a ribosome-dependent gtpase from yeast distinct from elongation factor 2. | three proteins required for poly(u)-directed polyphenylalanine synthesis have been separated from yeast. two of the factors correspond to the elongation factors 1 and 2 described for other eukaryotic systems, according to the criteria of phenylalanyl-trna binding and diphtheria toxin-catalyzed adp-ribosylation. the third protein, while absolutely required for polyphenylalanine synthesis, was a more active ribosome-dependent gtpase than elongation factor 2. | 1976 | 174100 |
| phosphoprotein phosphatase activity in the thyroid. | phosphoprotein phosphatase activity in the calf thyroid was found in various subcellular fractions. the relative amount in each fraction varied according to the substrate used: the 500g fraction had the highest specific activity when protamine was used, while the 5000g fraction was highest when histone was used. triton x-100 tended to increase activity in all the particulate fractions, the greatest change being found in the 105,000g pellet. deae chromatography of the 105,000 g supernatant resolv ... | 1975 | 174136 |
| substrate specificity of lecithin:cholesterol acyltransferase. esterification of desmosterol, b-sitosterol, and cholecalciferol in human plasma. | desmosterol and beta-sitosterol were esterified when incubated with normal human plasma. the initial rate of demosterol esterification was 1.7 times faster, and that of beta-sitosterol 0.4 times slower, than the esterification rate of cholesterol. these ratios were found to be almost the same when plasma from different normal individuals was tested. plasma from a patient with familial lecithin:cholesterol acyltransferase deficiency did not esterify any of the sterols. the esterification of desmo ... | 1975 | 174187 |
| [some physicochemical properties of the dysenteric therapeutic--prophylactic newcastle phages h-17 and h-18 (author's transl)]. | some physico-chemical properties of dysentery therapeutic-prophylactic newcastle-phages h-17 and h-18 were studied. both phages were shown to be resistant to sodium dodecyl sulphate at room temperature. phage h-17 at room temperature was completely inactivated and phage h-18 inactivated by 40% by 1 m sodium hydrochloride. phage h-18 was completely inactivated by 4 m sodium hydrochloride. morphology and sizes of the phages are described. the buoyant density of phage h-17 was found to be 1.497 g/c ... | 1975 | 174322 |

| mononucleosis-associated subacute sclerosing panencephalitis. | a thirteen-year-old girl died of subacute sclerosing panencephalitis (sspe) which occurred as part of a complex encephalitic illness related to acute infectious mononucleosis. the cerebrospinal fluid (csf) epstein-barr virus (ebv) fluorescent antibody (fa) titer was 1:64. electron microscopic examination revealed 17 nanometer (nm) diameter paramyxovirus-like nucleocapsids in brain sections and 90 nm diameter herpes virus-like enveloped particles in negatively stained brain tissue extracts. indir ... | 1976 | 175632 |
| immunopathogenicity and oncogenicity of murine leukemia viruses. ii. infection of mice and rats with scripps leukemia virus. | the pathologic consequences of infection of newborn mice and rats with mulv (scripps leukemia virus--slv) were observed. serum mulv p30 concentrations of most strains were elevated 20 to 100 times that of controls while mulv gp70 levels were elevated only 1.1 to 14.8 times, probably reflecting in part the higher concentrations of gp70 in control sera but also indicating the lack of parallelism in regulation of synthesis of these two viral antigens. infected mice of most strains developed immunol ... | 1976 | 175661 |
| lesions resembling gout in patients with rheumatoid arthritis. | although roentgenographic appearances are seldom important in establishing the diagnosis of rheumatoid arthritis or gout, atypical appearances of individual lesions may confuse the distinction between these two conditions. sixteen patients with rheumatoid arthritis were selected to illustrate joint and soft tissue lesions which resemble gout. the lesions are divided into five broad categories on the basis of the appearance and sites of bone erosion as well as the nature of soft tissue changes. s ... | 1997 | 175682 |

| an in vitro system for studying insulin release caused by secretory granules-plasma membrane interaction: definition of the system. | 1. an in vitro system is described in which insulin beta-granule-plasma membrane interaction can be studied. 2. the system shows an absolute requirement for physiological amounts of ca2+ (2 mum) in order for insulin release to proceed. 3. atp (5 mum) is abot to augment the ca2+ effect. 4. glucose (17 mm) alone does not cause insulin release but in the presence of ca2+ is as effective as atp. 5. when glucose, atp and ca2+ are added together a positive cooperative effect is produced with over 85% ... | 1976 | 178856 |
| neurochemical changes in the cat's spinal cord due to orthodromic tetanic stimuli. i: phospholipids. | posttetanic potentiation of monosynaptic reflexes has been used as a paradigm for neuronal plasticity. the explanation for this phenomenon is an increased responsiveness of the synaptic junctions. this would basically require chemical changes of the nervous structures involved. the ventral horn area of the spinal cord was therefore analyzed neurochemically. the determination of the phospholipids revealed an alteration of their composition. sphingomyelin, phosphatidylcholine and phosphatidylinosi ... | 1975 | 178883 |
| mechanism of plasma cyclic amp response to hypoglycemia in man. | the effect of insulin-induced hypoglycemia on plasma cyclic amp levels was studied in normal volunteers, adrenalectomized, and sympathectomized subjects. significant increases in plasma glucagon were observed in all groups. normal subjects all had two- to threefold rises in plasma camp while no response was seen in any adrenalectomized or sympathectomized subject. these findings suggest that the mechanism for enhanced plasma camp release during insulin-induced hypoglycemia is catecholamine depen ... | 1976 | 178982 |

| transfer of parental immunity to infectious laryngotracheitis in chicks. | the transfer of parental immunity to infectious laryngotracheitis was appraised by measuring serum antibody levels in 150 chicks from the day of hatch up to five weeks. the breeder flock which had received primary vaccination at eight weeks and a booster at 20 weeks transferred high antibody levels which fell markedly within two weeks and remained constant thereafter. chicks whose parents were vaccinated at 20 weeks only, had low antibody levels throughout. these low levels, in either group of c ... | 1976 | 187298 |
| inhibition of herpesvirus saimiri replication by phosphonoacetic acid, benzo(a)pyrene, and methylcholanthrene. | the present investigations were undertaken to determine the possible effects of two carcinogenic polycyclic aromatic hydrocarbons, benzo(a)pyrene and 3-methylcholanthrene on herpesvirus saimiri replication. the results from these experiments were compared with the effects of phosphonoacetic acid on the virus replication cycle. phosphonoacetic acid inhibited the synthesis of virus-induced intracellular late antigens, membrane antigens and infectious virus but not the synthesis of the early antige ... | 1977 | 187336 |
| sclerosteosis - an autosomal recessive disorder. | sclerosteosis is a rare, potentially lethal skeletal disorder in which massive bony over-growth leads to facial distortion, cranial nerve compression and progressive rise in intracranial pressure. gigantism and syndactyly of the 2nd and 3rd fingers are associated features. in a nationwide investigation in south africa, 25 affected individuals in 15 afrikaner kindreds have been studied. the minimum prevalence of the contition in this community is 1 in 75,000. analysis of pedigree data confirms th ... | 2003 | 187366 |
| the xeroradiographic appearances of some uncommon malignant mammary neoplasms. | the clinical and xeroradiographic appearances are described of four patients with malignant lymphomatous involvement of the breast, two with breast involvement by acute leukaemia, and four with primary fibrosarcoma of the breast. in one patient with malignant lymhoma and multiple palpable masses, the radiological appearance resembled benign mammary dysplasia, but in the three other patients, one with a discrete clinical mass, and two with diffuse clinical involvement, radiological examination of ... | 2003 | 187368 |

| [determination of free and protein bound cortisol, transcortin binding capacity and adrenocorticotropic hormone in the plasma of patients with hypertension]. | the total non-conjugated plasma cortisol in 60 patients with hypertension disease (hd)is 17.5 mkg/ml. the free non-conjugated cortisol represents 8.45 per cent of the total - 1,5 mkg%, considerably (p less than 0.0001) higher than that in healthy subjects. protein conjugated cortisol is 16.0 mkg%. the bounding capacity of transcortin the plasma of hypertonics is considerably decreased (p less than 0.0001) - 15.8 mkg (in healthy - 18.5 mkg) per 100 ml. acth level in the plasma of patients with hd ... | 1994 | 188262 |
| cell surface markers on epithelial-burkitt hybrid cells superinfected with epstein-barr virus. | attempts were made to superinfect two epithelial-burkitt hybrid cell lines, designated d98/hr-1 and d98/raji, with epstein-barr virus (ebv) and to investigate the expression of some cell surfacr markers including histocompatibility antigens, and the presence of b-cell markers, such as receptors for the third complement component and for monkey red blood cells. successful superinfection of d98/hr-1 cells with ebv was made evident by the expression of early antigen and, to a lesser extent, virus c ... | 1977 | 193641 |
| purification and subunit composition of guanosine 3':5'-monophosphate-dependent protein kinase from bovine lung. | the guanosine 3':5'-monophosphate-dependent protein kinase from bovine lung was purified to apparent homogeneity by affinity chromography using 8-2-aminoethylthio-cgmp coupled to sepharose 4b. the kinase activity was purified approximately 6000-fold with an overall recovery of approximately 20%. the product isolated by affinity chromatography contained both cgmp-binding and cgmp-dependent histone kinase activity, indicating that the enzyme was not dissociated into regulatory and catalytic compon ... | 1977 | 193862 |
