Synthesis of RNA by mutants of vesicular stomatitis virus (Indiana serotype) and the ability of wild-type VSV New Jersey to complement the VSV Indiana ts G I-114 transcription defect.

The ability of certain vesicular stomatitis virus (VSV; Indiana serotype) temperature-sensitive (ts) mutants to synthesize intracellular viral complementary RNA (vcRNA) at permissive or nonpermissive temperatures for productive infections has been investigated. Mutants belonging to complementation groups II, III, and V synthesize RNA at nonpermissive temperature in amounts essentially equivalent to that obtained at permissive temperatures. Mutant ts G I-114 possesses a thermolabile transcriptase and does not synthesize vcRNA at 40 degrees C; however, mutants ts O I-5, O I-53, O I-78, and O I-80 possess thermostabile transcriptases that are capable of some vcRNA synthesis at 40 degrees C. All five group I mutants are defective in their secondary transcription ability at 40 degrees C. Wild-type VSV New Jersey virus is able to complement the transcription defect of ts G I-114 at 40 degrees C. This complementation is inhibited by puromycin, suggesting that a viral gene product of VSV New Jersey (e.g., its transcriptase or a transcriptase component) is involved. Mokola virus is not able to complement the ts G I-114 defect, although Mokola does synthesize vcRNA in infected cells (in the presence or absence of cycloheximide).

An experiment in health careers recruitment: a summer program at Indiana University.

During the summer of 1973, the Indiana University Division of Optometry, via a Special Project Grant from the National Institutes of Health, conducted its first Summer Institute in the Health Related Professions for High School and College Students. Twenty-seven high school students and twenty-nine college students were brought to Indiana University for intensive sessions in career awareness, curriculum and financial counseling, and academic coursework. Assisted by the staffs of Indiana Health Careers, Inc. and the Indiana University Coordinators for School Science, the Institute awakened new interests and goals, relative to the health career prospectus, within the trainees. As a direct consequence of the summer program, four participants in the college institute were matriculated into schools of medicine, pharmacy, and optometry during the semester following the culmination of the Institute; ten more are participating in the followup program for continued guidance and counseling, seeking 1974 entrance into health professions schools and colleges. This experiment in health professions recruitment for minority, disadvantaged, and low-income students proved to be a viable method of increasing the manpower pool of health professionals.

Coinfection with a rhabdovirus: vesicular stomatitis virus of Indiana and New-Jersey serotypes.

Coinfection of cells with vesicular stomatitis virus (VSV) of Indiana and New-Jersey serotypes were performed. Thermosensitive mutants (ts) of VSV Indiana and the wild type strain (+) of New-Jersey were used. Harvests and titrations were made at permissive(PT) and nonpermissive (NPT) temperatures. It was shown that the harvest was mainly composed of one parental-like infectious particles. The dominance of one serotype over the other was shown to be a function of the relative multiplicity of the two viruses; the presence of a thermosensitive lesion imparts a disadvantage to the corresponding serotype. Non parental-like particles were also detected. As expected, these particles were detected only in two conditions. 1) Harvest performed at NPT and titrations allowed at PT.- Most of the infectious particles (i.e. twin particles) resistant to anti-Nj serum developped a plaque (i.e. mixed-plaque)containing virions of both serotypes: Indiana (ts) and New-Jersey (+). After sonication or EDTA treatment of the harvest, prior to titrations, no more mixed-plaques were formed. Examination of the harvest by electron microscopy showed that 7-17 % of the particles formed aggregates; therefore, it is likely that the twin-particles are in fact aggregates. 2) Harvest performed at PT and titrations allowed at NPT.-It has been shown that 1 % of the wild type infectious particles was resistant to anti-Nj serum even though being of Nj genotype. It was inactivated by a mixture of anti-Nj and anti-In sera and therfore behave as pseudotypes. But since twin particles, when plated at Nt, would give rise to an homogenous progeny from New-Jersey (+), they could be confused with pseudotypes. Under those conditions there is no absolute evidence that phenotypic mixing really occurs between VSV of Indiana and New-Jersey serotypes.

Prion protein preamyloid and amyloid deposits in Gerstmann-Sträussler-Scheinker disease, Indiana kindred.

Gerstmann-Sträussler-Scheinker disease (GSS) is a familial neurological disorder pathologically characterized by amyloid deposition in the cerebrum and cerebellum. In GSS, the amyloid is immunoreactive to antisera raised against the prion protein (PrP) 27-30, a proteinase K-resistant peptide of 27-30 kDa that is derived by limited proteolysis from an abnormal isoform of a neuronal sialoglycoprotein of 33-35 kDa designated PrPSc. Polyclonal antibodies raised against synthetic peptides homologous to residues 15-40 (P2), 90-102 (P1), and 220-232 (P3) of the amino acid sequence deduced from hamster PrP cDNA were used to investigate immunohistochemically the distribution of PrP and PrP fragments in the brains of two patients from the Indiana kindred of GSS. Two types of anti-PrP-immunoreactive deposits were found: (i) amyloid deposits, which were exclusively labeled by anti-P1 antiserum to residues 90-102 of PrP, and (ii) preamyloid deposits, which were labeled by all anti-PrP antisera but did not exhibit the tinctorial and optical properties of amyloid. The latter appeared as diffuse immunostaining of the neuropil that targeted to areas in which amyloid deposits were most abundant. They were partially resistant to proteinase K digestion and consisted ultrastructurally of amorphous, flaky, electron-dense material. These findings substantiate our previous observation that the major amyloid component in the GSS Indiana kindred is an internal fragment of PrP and indicate that full-length abnormal isoforms of PrP and/or large PrP fragments accumulate in brain regions most affected by amyloid deposition. These findings support the view that in the GSS Indiana kindred a stepwise degradation of PrP occurs in situ in the process of amyloid fibril formation.

HIV/AIDS education in Indiana public schools, grades 7-12.

Indiana secondary school principals were surveyed regarding HIV/AIDS education status in their schools. A questionnaire from the Centers for Disease Control was evaluated then modified for the survey. More than 520 school principals responded to the questionnaire mailed to all 680 school principals, grades 7-12, in Indiana. Most schools offer some form of HIV/AIDS education in grades 7-12. HIV education was taught by teachers with different educational backgrounds and school roles. Almost 60% of school principals believe students are at risk for HIV infection. Tests of statistical significance were conducted with regard to principals' opinions and actual practice of HIV/AIDS education in schools. Most schools have responded to the need for HIV/AIDS education, but with a variety of formats, teaching personnel, and teacher training.

Variant infectious bronchitis virus isolated from Indiana chickens.

Infectious bronchitis virus (IBV) associated with a catarrhal tracheitis, sudden decline in egg production, and reduced shell quality was isolated from an Indiana White Leghorn breeder flock. It was found to be serologically different from Massachusetts, Connecticut, Iowa 97, Iowa 609, Florida, Arkansas 99, JMK, Holte, Gray and SE 17 IBV serotypes. Two different Massachusetts vaccine strains protected chickens from respiratory signs but not against virus infection using the isolant for challenge in laboratory trials. The isolant was passed through a 0.22 mu. filter. It was heat (56 C), acid pH (3.0), ether and chloroform labile. In embryos it produced deaths or lesions of infectious bronchitis in one to five days after inoculation. It is suggested that this IBV isolant be designated Indiana-type.

A major focus of Legionnaires' disease in Bloomington, Indiana.

Thirty-nine cases of Legionnaires' disease in a 16-month period were identified in visitors to and residents of Bloomington, Indiana. Thirty-five patients had spent at least one night at the Indiana Memorial Union in the 2 weeks before becoming ill. Five of 32 sporadic cases nationwide between 1 January and 31 March 1978 were retrospectively shown to be in persons who had recently visited the Union. The risk of acquiring Legionnaires' disease as a Union visitor was at least 17 times greater than that for Bloomington residents 20 years or older. Employees who had worked at the Union 5 years or longer were more likely to be seropositive than workers in other Bloomington hotels. Legionnaires' disease bacterium was isolated from five environmental sites in Bloomington. A cooling tower may have been involved in disease spread, but it was not the only source. Hypochlorite solution was added to cooling tower water as a precautionary measure; however, one case was confirmed in a man with Union exposure 9 days after hypochlorite treatment had begun.

The prescription of transdermal nicotine patches for tobacco-using dental patients: current status in Indiana.

As Indiana dentists become involved in office-based smoking cessation efforts, they can prescribe the recently-developed Federal Drug Administration (FDA)-approved nicotine transdermal patch delivery systems for their smoking patients who wish to overcome nicotine addiction. This article reviews the evolutionary and scientific development of transdermal nicotine patch systems within an oral health setting. It discusses dental office-based cessation programs which have been designed by faculty members at the Indiana University School of Dentistry and by dentists who work with the National Cancer Institute. Finally, it presents the rationale for patch usage and specific techniques which are utilized in prescribing and monitoring this medication.

Investigation of an outbreak of velogenic viscerotropic Newcastle disease in pet birds in Michigan, Indiana, Illinois, and Texas.

An outbreak of velogenic viscerotropic Newcastle disease in exotic pet birds in the United States from April through July 1991 was investigated. More than 2,000 pet birds in 5 states (Michigan, Indiana, Illinois, Texas, and Maryland) were tested. Infected birds were found in Michigan, Illinois, Indiana, and Texas. This disease was eradicated without spread to domestic poultry. Epidemiologic investigations revealed the source of infection to be double yellow-headed Amazon parrots suspected to be illegally imported into Texas.

The pathogenesis of vesicular stomatitis virus, serotype Indiana, in Aedes aegypti mosquitoes, after imbibition of a viremic blood meal.

This study showed that Vesicular Stomatitis Virus (Indiana) in most instances was not capable of replicating in Aedes aegypti when imbibed by the mosquitoes on a viremic host. Rapid inactivation of the virus was observed in some cases within 24 hours after imbibition. Attempts to demonstrate virus inactivation by midgut contents in vitro were not successful.

Linkage of the Indiana kindred of Gerstmann-Sträussler-Scheinker disease to the prion protein gene.

The Indiana kindred variant of Gerstmann-Sträussler-Scheinker disease has amyloid plaques that contain prion protein (PrP), but is atypical because neurofibrillary tangles like those of Alzheimer disease are present. To map the position of the disease causing gene, we used three markers for linkage analyses. A missense mutation at codon 198 of the PrP gene (PRNP) is found in all definitely affected individuals and yields a maximum lod score of 6.37 (theta = 0). The disease also is concordant with the two other PRNP-region markers. These results demonstrate tight linkage of the disease-causing gene to PRNP and support the hypothesis that the codon 198 mutation is the cause of IK-GSS. Our studies also suggest that methionine/valine heterozygotes at PRNP codon 129 have a later age of onset of the disease than codon 129 valine/valine homozygotes.

Heterotypic exclusion between vesicular stomatitis viruses of the New Jersey and Indiana serotypes.

Co-infection of cells with vesicular stomatitis viruses of the Indiana and New Jersey serotypes results in interference. Using specifically-labelled immunofluorescent antibodies, it was demonstrated that within any one co-infected cell, one virus serotype replicated to the relative exclusion of the other serotype. This result was further substantiated by an examination of the virus serotypes released by infectious centres co-infected with both viruses. Dominance of one serotype over the other was shown to be a function of the relative multiplicity of the two viruses. Superinfection by the second serotype at a higher multiplicity resulted in dominance by the second virus during the early period (up to 1-5 h) post-infection. After this time, the minority virus was able to overcome this dominance. Dominance of the majority virus was also abolished by u.v; inactivation. Cell protein synthesis appeared to be less affected in cells infected with both serotypes than when infection was with a single serotype.

The pathogenesis of vesicular stomatitis virus, serotype Indiana, in Aedes aegypti mosquitoes. I. Intrathoracic injection.

Analysis of infectious virus particles after intrathoracic injection revealed that Aedes aegypti mosquito tissues are capable of supporting the growth of vesicular stomatitis virus (VSV), serotype Indiana. Although all tissues assayed (salivary gland, midgut, diverticulum, malphigian tubules, and ovary) were capable of supporting VSV growth, the salivary gland was the only organ capable of maintaining an appreciable amount of virus for periods longer than 9 days postinfection. Electron microscopic studies of infected tissues showed virus particles consistently within the cell cytoplasm of all organs with no evidence of nuclear involvement. Direct evidence of crystalline formation of VSV in the apical cavities of salivary gland tissue was demonstrated.

Clinical trials with ifosfamide: the Indiana University experience.

At Indiana University, we began clinical trials with ifosfamide in 1981. Although our initial efforts were in a variety of tumor types, including pancreatic cancer, we have most recently focused our attention on two tumors that have historically exhibited a higher degree of chemosensitivity--testicular cancer and small cell lung cancer (SCLC). In phase II trials, ifosfamide has proven to have single-agent activity in both diseases. Coupling this data with preclinical observations of synergy with cisplatin and etoposide, we began trials of ifosfamide plus cisplatin with either vinblastine (VeIP) or etoposide (VIP) in patients with recurrent germ cell tumors; we also investigated the use of VIP in SCLC. In third-line or greater therapy for recurrent germ cell tumors, a 36% disease-free status was attained, with 16% of patients continuously free of disease for 5 or more years. Currently, ifosfamide is being evaluated as part of initial therapy in patients with advanced disease. In SCLC, VIP has also been investigated as part of initial therapy in patients with extensive disease. The complete response rate of 38% achieved in 37 evaluable patients has spurred the Hoosier Oncology Group to compare the VIP regimen to cisplatin/etoposide in patients with extensive-disease SCLC. Ifosfamide has the broad range of clinical activity, but its ultimate role as part of initial therapy remains to be discerned.

Salmonella serotypes isolated from the aquatic environment (Wabash River, Indiana, 1973-1976).

During 1973-1976, 833 isolations of salmonellae were made from the aquatic biosphere of the Wabash River, Lafayette, Ind. Of the isolants, 643 were definitively serotyped. Salmonella typhimurium represented 34.4% of the cultures. Salmonella eimsbuettel previously had not been recognized in Indiana. A total of 35 serotypes and 1 untypable group C1 was obtained from the aquatic samples, ie, river water, river bottom sediment, fish, and mussels. Most of the isolants were presumed to be of human origin, because many samplings were made in close proximity to sewage treatment plant outfalls. During the survey period, epidemic salmonellosis had not been reported for the Lafayette-West Lafayette metropolitan area.

Cross-neutralization between vesicular stomatitis virus type Indiana and Chandipura virus.

Using highly potent immune sheep sera, it was possible to demonstrate that: (1) Two rhabdoviruses, classified in the Vesiculovirus genus on morphological grounds but previously considered unrelated, viz., the vesicular stomatitis virus type Indiana (VSV), and Chandipura virus (ChV), show a low-level, but distinct cross-neutralization. This was, in most combinations, considerably increased by complement. (2) The species of cells used for growing the viruses for immunization and for neutralization tests, influenced the level of cross-neutralization. (3) No cross-reaction between VSV and ChV could be detected in the immunodiffusion reaction. (4) Immune sera, raised in sheep by immunization with the two purified rhabdoviruses contained complement-dependent cytotoxic antibodies specifically reacting with the cell species used for growing the viruses.
