| [discovery of viroids and possible relationship with human and veterinary medicine]. | the researches of diener and co-workers and those of the semancik's group, have recently established that some plant diseases, such as potato spindle tuber, citrus exocortis disease and chrysanthemum stunt, are caused by a new class of pathogens, named viroids. these are the smallest known agents (they are smaller than viruses) having a molecular weight of ca 10(5) daltons, and composed of a highly structured rna, rich in guanine-cytosine base pairs without a capsid. little is known about the or ... | 1975 | 132907 |
| newer knowledge in comparative virology--its contribution to human health research. | like other comparative sciences, and despite its recent beginning comparative virology has already contributed useful applications and observations to human health research. teachings derived from the study of marek's disease found application in that of burkitt's lymphoma, and may lead to a possible vaccine against the human disease. equally useful information came from the study of canine distemper in the development of a chorio-allantoic membrane attenuated measles vaccine, and in our knowled ... | 1975 | 167504 |

| neurophysin in the brain and pituitary gland of normal and scrapie-affected sheep--i. its localization in the hypothalamus and neurohypophysis with particular reference to a new hypothalamic neurosecretory pathway to the median eminence. | by use of an immunofluorescence histochemical technique with a cross-species reactive antiserum to porcine neurophysin-ii the precise localization of neurophysin in the pituitary gland and the hypothalamic area of the brain of the sheep has been determined. neurophysin was confined to neurosecretory pathways originating from the supraoptic and paraventricular hypothalamic nuclei. the major pathway terminates in the neurohypophysis but in addition a second neurophysin-containing pathway proceeds ... | 1976 | 11370513 |

| genetic markers in herdwick sheep: no correlation with succeptibility or resistance to experimental scrapie. | genetic markers were studied in herdwick sheep, bred at compton, with special reference to genetically selected lines which differ in susceptibility or resistance to experimentally produced scrapie. there were no correlations between susceptibility to the disease and albumin, pre-albumin, esterase and haemoglobin phenotypes, and between reduced glutathione levels and alpha-mannosidase isoenzymes, the latter possibly representing a previously undescribed genetic marker in sheep. | 1977 | 606000 |

| replication of the scrapie agent in ocular neural tissues. | optic nerves and retinas removed from hamsters experimentally inoculated with the scrapie agent contain a high titer of infectivity. ophthalmoscopic examination of these animals revealed gross lesions of retinopathy as early as 3 weeks before the onset of clinical signs of brain degeneration. these results suggest that the scrapie agent may spread centrifugally in nerve fibers after intracerebral inoculation and that the scrapie-associated retinopathy seen in hamsters is directly induced by the ... | 1980 | 6767244 |
| virologic and neurohistologic findings in dairy goats affected with natural scrapie. | virologic and neurohistologic findings in three dairy goats that became affected with scrapie while living with naturally infected suffolk sheep were essentially like those in affected sheep. virus, detected by mouse inoculation, was widespread in non-neural sites, particularly in lymphatic tissues and intestine. im most sites, titers of virus ranged from 3.0 to 3.5 log10 mouse intracerebral ld50/30 mg of tissue. virus was in nervous tissue in much higher titer. ranging from 5.1 to 5.8 log10, th ... | 1980 | 6767304 |
| sensitivity of scrapie infectivity to detergents and 2-mercaptoethanol. | exposure of fractions obtained from scrapie-infected mouse brain to triton x-100 resulted in no change in its infectivity except after sedimentation. infectivity was reduced after exposure to 2-mercaptoethanol but only in the presence of sds. these results support the view that protein is an important component of the scrapie agent and that disulfide bonds may play a part in maintaining the structural integrity of the infectious agent. | 1980 | 6768695 |

| scrapie agent contains a hydrophobic protein. | the scrapie agent causes a degenerative nervous system disorder of sheep and goats. considerable evidence indicates that the scrapie agent contains a protein that is necessary for infectivity [prusiner, s. b., groth, d. f., cochran, s. p., masiarz, f. r., mckinley, m. p. & martinez, h. m. (1980) biochemistry 19, 4883-4891], but direct demonstration of a protein moiety has been hampered by lack of sufficiently purified preparations. employing preparations of the scrapie agent enriched 100- to 100 ... | 1981 | 6273882 |
| ultrastructural cytochemical studies of cerebral microvasculature in scrapie infected mice. | alkaline phosphatase, 5'-nucleotidase nucleoside diphosphatase and thiamine pyrophosphatase activities were studied by cytochemical method applied to electron microscopy of brain microvasculature in normal and scrapie infected mice. in control mice, the major location of all phosphatases studied was the luminal plasma membrane of the endothelial cells. in scrapie infected mice, changes in activity and distribution of the above mentioned phosphatases manifested themselves in the appearance of the ... | 1981 | 6111887 |

| inability to transmit scrapie by transfection of mouse embryo cells in vitro. | infectivity of nucleic acid from highly infectious mouse scrapie brains was studied by transfecting the nucleic acid in vitro prior to inoculation into animals. foetal mouse brain and whole mouse embryo cultures were chosen as the cells used for the transfection. as an internal control, infectious nucleic acid was recovered from bacteriophage phi x174 and whole virus particles were obtained when cultures were transfected with herpes simplex virus dna. in contrast, none of the animals inoculated ... | 1982 | 6278059 |
| changes in the nigrostriatal system following microinjection of an unconventional agent. | the effect of apomorphine, a direct dopamine receptor agonist, was studied in golden hamsters after unilateral injection of scrapie agent (strain 263k) into the nigrostriatal system. twenty-five received an injection into the left striatum and 24 into the left substantia nigra. varying volumes (5, 1 and 0.5 microliterss) and dilutions of the homogenate (10(-2), 10(-3), 10(-4)) were used. the duration of the incubation period (delay of appearance of clinical signs of the disease) was dependent on ... | 1982 | 6807492 |
| experimental scrapie in golden syrian hamsters: temporal comparison of in vitro cell-fusing activity with brain infectivity and histopathological changes. | golden syrain hamsters were inoculated intracerebrally with the hamster-adapted 263k strain of scrapie virus, and the evolution of in vitro cell fusing activity induced by brain suspensions was compared with brain infectivity titers and histological changes. cell-fusing activity abruptly appeared 4 weeks after inoculation, 1 week before the earliest detectable histopathological changes, at an infectivity level of 7.6 log 50% lethal doses per g of brain. cell-fusing activity was sustained through ... | 1982 | 6809626 |

| scrapie-associated fibrils in creutzfeldt-jakob disease. | scrapie of sheep, and creutzfeldt-jakob disease (cjd) of man belong to a group of transmissible encephalopathies which have been successfully transmitted to a variety of hosts. in susceptible hosts, these diseases are characterized by progressive degeneration of the central nervous system leading inevitably to death. the agents responsible for these diseases have not yet been identified, but they exhibit similar physicochemical characteristics. abnormal fibrils designated 'scrapie associated fib ... | 1983 | 6358899 |
| ultrastructural morphology of amyloid fibrils from neuritic and amyloid plaques. | the structure of partially purified, cns amyloid fibrils from three different sources have been compared by negative stain em. the fibrils isolated from brains with senile dementia of alzheimer type were 4-8 nm in diameter, narrowing every 30-40 nm and apparently composed of two 2-4 nm filaments. the fibrils from a gerstmann-sträussler syndrome brain were 7-9 nm in diameter, narrowing every 70-80 nm and with a suggestion that they are composed of two 3-5 nm filaments. the fibrils isolated from 8 ... | 1983 | 6683919 |
| scrapie in france: some possible predisposing factors in the naturally-acquired disease of sheep. | a nationwide survey of the occurrence of scrapie in france during the 12-year period 1968-1979 has shown the disease to be more widespread than previously thought. the data suggest that certain sheep raising practices, such as transhumance (nomadic grazing), pen and pasture alternations, and use of animals for milk production, may play a possible role in disease prevalence. | 1983 | 6685940 |

| sheep lymphocyte antigens and scrapie. | the frequencies of 15 lymphocyte antigens were determined in 2 experimental flocks of herdwick sheep derived from the same foundation stock. the blue flock had been bred for resistance, and the red flock for susceptibility, to a standard dose of the ssbp/1 source of scrapie injected subcutaneously. although there were marked frequently differences between the 158 red flock and 51 blue flock sheep tested these differences could be attributed to genetic drift. within the red flock no significant f ... | 1984 | 6470228 |
| [karyological characteristics of continuous mouse cell lines infected with the scrapie agent]. | a karyological study of murine cell line l, latently infected with different strains of the scrapie agent (compton and c-506) showed that the both variants number of chromosomes and the number of robertson's translocations of chromosomes decrease insignificantly with an increase in the time of subcultivation. the use of the c-method of differential chromosome staining revealed four new analogous chromosomes in both experimental cell lines. this phenomenon is probably specific for this infected c ... | 1984 | 6539520 |
