Dispersal of new nests within and across hives of solitary bees and wasps.(1905-06-24) Hallett, PeterOntario Ecology and Ethology Colloquium, abstract, 2002.Item A Stone-Weierstrass theorem for group representations(1978-01-01) Repka, JoeIt is well known that if G is a compact group and π a faithful (unitary) representation, then each irreducible representation of G occurs in the tensor product of some number of copies of π and its contragredient. We generalize this result to a separable type I locally compact group G as follows: let π be a faithful unitary representation whose matrix coefficient functions vanish at infinity and satisfy an appropriate integrabillty condition. Then, up to isomorphism, the regular representation of G is contained in the direct sum of all tensor products of finitely many copies of π and its contragredient.We apply this result to a symplectic group and the Weil representation associated to a quadratic form. As the tensor products of such a representation are also Weil representations (associated to different forms), we see that any discrete series representation can be realized as a subrepresentation of a Weil representation.Item The Spectroscopy of Transition States in H+H2 Reaction, and NaI Photodissociation(1983-01-01) Foth, H.-J.; Mayne, H. R.; Poirier, R. A.; Polanyi, J. C.; Telle, H. H.(a). We have computed an approximate absorption spectrum for unstable intermediates H3≠ which constitute the transition states in the fundamental exchange reaction H+H2→H3≠→H2+H. Reaction takes place across the Siegbahn, Liu, Truhlar, Horowitz(SLTH) ground state energy surface, and electronic excitation is to the bound statethat correlates with H*(22P)+H2. Features in the spectrum are indicative of thefavored turning points for the mean of many classical trajectories across the SLTHsurface. (b). Preliminary experimental data are reported which give evidence of emissionarising from the transition states of NaI≠* in the (cw or pulsed) photolysis ofNaI→222nmNaI≠*→Na*(32P)+I.The observed transition state emission is compared with a simple calculation.Item The world of the newborn(New York: Basic Books, 1988) Maurer, Daphne; Maurer, CharlesA prominent psychologist known for her work on infant behavior and a science writer-photographer together provide a remarkable picture of infancy from the baby's own perspective.Item Quadratic subfields on quartic extensions of local fields(1988-01-01) Repka, JoeWe show that any quartic extension of a local field of odd residue characteristic must contain an intermediate field. A consequence of this is that local fields of odd residue characteristic do not have extensions with Galois group A4 or S4. Counterexamples are given for even residue characteristic.Item The Approach to Carcinoma of the Proximal Hepatic Ducts: More Radical or More Conservative(1989-01-01) Langer, B.Item Survey of Neisseria gonorrhoeae Antimicrobial Susceptibility in Ontario(1990-01-01) Loo, Vivian G; Simor, Andrew E; Jaeger, Ruth; Low, Donald EThe minimal inhibitory concentrations (MICs) of penicillin, tetracycline, erythromycin, cefoxitin, ceftriaxone and spectinomycin were determined for 300 consecutive strains of Neisseria gonorrhoeae collected from physicians’ offices in Ontario. Only four isolates were found to produce beta-lactamase. Of the remaining 296 isolates, five (1.7%) had penicillin MICs greater than or equal to 1 mg/L, 78 (26.3%) had tetracycline MICs greater than or equal to 1 mg/L, 13 (4.4%) had cefoxitin MICs greater than or equal to 1 mg/L and 43 (14.5%) had erythromycin MICs greater than or equal to 1 mg/L. Two isolates (0.7%) had high level tetracycline resistance with MICs greater than or equal to 16 mg/L. All N gonorrhoeae isolates were susceptible to ceftriaxone and to spectinomycin.Item Coalition vs. racism(Centre for Women's Studies in Education, 1990-10-01) Taylor, Barbara ; Silversmith, DoreenItem A Review of Tuberculous Meningitis in a Canadian Pediatric Hospital(1991-01-01) Navas, Lissette; Wang, ElaineTuberculous meningitis is a disease associated with high morbidity and mortality. Experience with this disease at the Hospital for Sick Children in Toronto was reviewed to determine whether changes in prognosis have occurred in the past decade. All patients from whom the organism was recovered from the cerebrospinal fluid, or who had a positive Mantoux test in association with a compatible history, were included. Thirteen patients were identified from 1978 to 1989. The median age was six years (range 11 months to 17.5 years). Nine patients were born in Canada, but all except one were members of recently immigrant families. History of close contact with an adult with tuberculosis, or travel to an endemic area in the preceding six months, was present in seven cases. All patients had clinical manifestations and mild pleocytosis with elevated protein content in the cerebrospinal fluid. Patients were all diagnosed within 20 days after admission (median one day). Computed tomography scan of the head was abnormal in all patients within three weeks of admission. No patient died, although long term sequelae developed in five. The prognosis of tuberculous meningitis has improved in the past decade. Although a specific reason for this improvement cannot be definitively stated, earlier diagnosis and better chemotherapy may contribute.Item Blunt Liver Trauma at SunnybrookMedical Centre: A 13 Year Experience(1991-01-01) Hanna, Sherif S.; Pagliarello, G.; Taylor, G.; Miller, H.; Scarth, H. M. C.; Brenneman, F.Between June 1, 1976 and June 30, 1989 The Regional Trauma Unit at Sunnybrook Medical Centre inToronto, Ontario, Canada received 3730 patients. Of these 335 (9%) sustained a liver injury, 95% beingdue to blunt trauma. Open peritoneal lavage was performed on 80% of liver trauma patients (267/335),99% being true positive.A laparotomy was performed on 97% of patients (324/335). Major surgical treatment was required in132 patients (41%) and minor treatment in 192 patients (59%). The remaining 11 patients were treatedconservatively (n = 3) or died during resuscitation (n = 8).Morbidity directly related to the liver injury was seen in 29 of 249 surviving patients (11%) althoughoverall morbidity was 27% (67/249). Reoperation was required in 6% (14/249) with abscess orhematoma accounting for 11 of 14 operations.The overall mortality rate was 26% (86/335). Eighty two percent of patients (n = 276) had a grade I, IIor III liver trauma according to Moore’s classification with a mortality of 12% (n = 32). The remaining18% of patients (n = 59) had a grade IV or V liver trauma with a mortality of 44% (n = 26). Of the 86deaths, head injury accounted for 48 (56% of deaths); liver hemorrhage for 17 (20%), liver sepsis for(1%) and other causes for 20 deaths (23%). Thus death due to the liver injury itself (hemorrhage andsepsis) occurred in 18 out of 335 patients (5% overall). Head injury accounted for the death of 48 out of335 patients (14% overall).Over the past 13 years a trend has occurred at our institution whereby we are seeing less liver traumain our population of multiply injured patients from 12% (1976–1983) down to 7% (1985–1989); with agradual decline in overall mortality from 32% (1976–1983) to 19% (1985–1989), whereas the precentageof deaths due to head injuries and liver injury have increased.Item Imported Arbovirus Infections in Canada 1974-89(1991-01-01) Artsob, Harvey; Spence, LeslieFrom 1974 to 1989, sera from symptomatic patients with histories of recent travel outside Canada were tested for antibodies to several arboviruses, principally of the alphavirus and flavivirus families. Diagnostic seroconversions were documented in 84 individuals from six provinces, including one alphavirus (Chikungunya) and 83 flavivirus seroconvertors. Dengue 1 virus was isolated from the blood of one patient. Most flavivirus seroconvertors were likely infected with dengue virus, but infections with tick-borne encephalitis, St Louis encephalitis and Powassan viruses were also recognized. Patients had histories of recent travel to the Caribbean, South America, Asia, Africa, North America (outside Canada), Tahiti, Fiji and Europe. Possible imported infections due to Japanese encephalitis, Ross River, western equine encephalitis and Colorado tick fever viruses were also encountered.Item Clinical Significance and Characterization of AZT-Resistant Strains of HIV-1(1991-01-01) Wainberg, Mark A; Rooke, Ronald; Tremblay, Michel; Li, XuGuang; Parniak, Michael A; Gao, Qing; Yao, Xiao-Jian; Tsoukas, Chris; Montaner, JSG; Fanning, M; Ruedy, JA number of laboratories have now independently confirmed that zidovudine (AZT)-resistant strains of human immunodeficiency virus type 1 (HIV-1) may be isolated from patients undergoing prolonged therapy with this drug. In certain instances, such drug-resistant viral isolates have been obtained from patients with clinical acquired immune deficiency syndrome (AIDS), while in others, isolation of drug-resistant strains has been achieved in the case of HIV seropositive, asymptomatic subjects. Most of the evidence points to a series of mutations within the polymerase gene of HIV-1, which encodes viral reverse transcriptase, as being responsible for development of the drug-resistant phenotype. It further appears that over 50% of patients treated with AZT for periods longer than six months are likely to yield drug-resistant strains of HIV-1 in their circulation. Furthermore, the development of drug resistance soon after initiation of AZT therapy may potentially be correlated with the likelihood of AZT treatment failure. In several instances, cross resistance has been observed between AZT and other nucleosides being considered for potential therapy of HIV-1-associated disease.Item Developmental Expression of IL-2-Receptor Light Chain (CD25) in the Chicken Embryo(1991-01-01) Fedecka-Bruner, Barbara; Penninger, Josef; Vaigot, Pierre; Lehmann, Anne; Martínez-A., Carlos; Kroemer, GuidoThymocyte differentiation obeys the same fundamental principles in mammals as in avianspecies. This parallelism does not only affect the developmentally controlled acquisition ofCD3, 4, 8, and TcR isotype expression, but also concerns CD25, the light chain of the interleukin-2 receptor (IL-2R). On chicken thymocytes, surface CD25, which is recognized by themonoclonal antibody INN Ch16, is first observed during day 11 of embryonic life, and peaksat day 14, when it is expressed by about one-third of all lymphoid cells. CD25 is found onsubsets of all ,thymocyte populations as defined by TcRαβ, TcRγδ, 2, CD4, and CD8 expression,cortical or medullary localization, and is also present on a subset of intrathymic nurse-celllymphocytes. These findings suggest phylogenetic conservation of the IL-2/IL-2R-triggereddifferentiation pathway previously described for mammalian species, thus under-liningits probable functional importance.Item Pathogenesis of Cholesterol Gallstones(1991-01-01) Strasberg, Steven M.; Clavien, Pierre-Alain; Harvey, P. Robert C.Cholesterol gallstone disease is extremely common. Three major stages are recognized for stoneformation, namely bile that becomes supersaturated with cholesterol, cholesterol nucleation leading tocrystal formation and finally retention of the crystals in the gallbladder resulting in stone formation.Supersaturation is common but nucleation into crystals probably requires protein nucleating factors.Impaired motility of the gallbladder causes crystal retention and is probably very important in stoneformation.Item Black women's oral history project(Centre for Women's Studies in Education, 1991-10-30) Hill, RuthItem Comparative Antifungal Activity of Cilofungin (LY121019) against Candida Species, Including Evaluation of Susceptibility Testing Method(1992-01-01) Chagla, Abdul H; Hii, John H; Hoban, Daryl J; Simor, Andrew E; Ferro, Santiago; Witwicki, Evelyn; Poon, Ruby; Low, Donald EThe in vitro activity of cilofungin against 100 Candida species was compared with 5-flucytosine. amphotericin B and ketoconazole by two laboratories independently and in a blinded fashion using a macrotitre dilution broth method in saam-f medium. Cilofungin showed good in vitro activity against Candida albicans. Candida tropicalis and Candida glabrata (90% minimal inhibitory concentration [MIC] 3.2 μg/mL) but was inactive against other Candida species. When testing the susceptibility of cilofungin, 5-flucytosine and amphotericin B at the two centres, approximately 90% of the Candida strains had MICs differing by fourfold or less. However, when testing susceptibility of ketoconazole, only 51% of the Candida strains had MIC differences fourfold or less. MIC susceptibility testing with cilofungin, 5-flucytosine and amphotericin B in saam-f medium is reproducible.Item Comparative Evaluation of Seven Commercial Tests for Detection of Heterophile Antibody in Infectious Mononucleosis(1992-01-01) Skulnick, Martin; Low, Donald E; Simor, Andrew E; Patel, Mohan; George, Pauline; Chua, RobertDetection of heterophile antibodies in infectious mononucleosis is the most rapid and cost-effective method for confirming the clinical diagnosis of the disease. This study compared seven commercial test kits (the Oxoid Infectious Mononucleosis Kit [Oxoid Ltd], Immunoscan Im-Latex [Baxter Travenol], Mono-Latex [Wampole Laboratories], Monospot and Im Screen Test [Ortho Diagnostics], Immunoscan Im-RBC Test [Baxter Travenol], and Infectious Mononucleosis Test [NCS Diagnostics]) to the Davidsohn differential test. All of the kits were shown to be acceptable for use, with specificities and sensitivities greater than 96.5% and 95.5%, respectively.Item Comparative Antifungal Activity of Cilofungin (LY121019) against Candida Species, Including Evaluation of Susceptibility Testing Method(1992-01-01) Chagla, Abdul H; Hii, John H; Hoban, Daryl J; Simor, Andrew E; Ferro, Santiago; Witwicki, Evelyn; Poon, Ruby; Low, Donald EThe in vitro activity of cilofungin against 100 Candida species was compared with 5-flucytosine. amphotericin B and ketoconazole by two laboratories independently and in a blinded fashion using a macrotitre dilution broth method in saam-f medium.
