Earlier we reported a reduction to 1/30th-1/100th of the original number of infectious particles in the infectious vesicular stomatitis virus (VSV) released from L cells treated with 10 or 30 reference units of interferon per ml. However, in these cultures virus particle production, as measured by VSV particle-associated viral RNA, virus nucleocapsid(More)
Using a method for freeze-drying intact cells, uninfected and murine leukemia virus (MuLV)-infected JLSV9 cell surfaces, as well as murine mammary tumor virus (MuMTV)-infected cell surfaces, were examined by electron microscopy. The 10-nm knobs of MuLV and the 5-nm spikes of MuMTV were clearly revealed on the surfaces of budding viruses and were also found(More)
PURPOSE The purpose of this retrospective study was to determine the prevalence of surgical site infection (SSI) after orthognathic surgery at the Department of Oral and Maxillofacial Surgery of Capital Health and Dalhousie University (Halifax, NS, Canada). PATIENTS AND METHODS A retrospective chart review of all patients undergoing orthognathic surgery(More)
Reactivity of B16 melanoma cell surface proteins with antisera to the major envelope glycoprotein, gp70, of murine leukemia viruses was assessed by radioimmunoprecipitation and sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Surface proteins from cultured monolayers of the B16 melanoma and variant lines B16-F1, B16-F1(1r6), B16-F10, and(More)
In vitro cultured cells are connected by different membrane junctions which may serve as a matrix for the monolayer, but which may also enable intercellu­ lar communication. Some of these intercellular infor­ mation exchanges may be detected by ionic coupling between the cells through so-called “low-resistance junctions” . Gilula and cow orkers1, for(More)
