27. Detection of antibodies to alphaviruses by enzyme-linked immunosorbent assay.
Cell culture-derived antigens detected antibodies to alphaviruses in human sera with the enzyme-linked immunosorbent assay technique. Results correlated with those from hemagglutination inhibition and neutralization tests.

28. Heterotopic Heart Transplantation in Three Patients at the Texas Heart Institute
Seventy-three orthotopic and three heterotopic transplantations have been done in our institution, and in this report, we describe the procedure and outcome of those who underwent heterotopic transplantation.

29. Cardiac Transplantation in a Patient with Septicemia After Prolonged Intraaortic Balloon Pump Support: Implications for Staged Transplantation
After initial support with an intraaortic balloon pump, and since the introduction of cyclosporine for immunosuppression, five patients have undergone cardiac transplantation in our institution with good results. Not one of these patients died of sepsis in the immediate postoperative period. We report the clinical course of one such patient to show the advan

30. Current methods for circulatory support.
Although the concept of artificial circulatory support has existed for almost 200 years, it has only been within the last 4 decades that engineers and physicians have developed mechanical devices that can 1) temporarily support the circulation in a patient until the heart recovers or a new heart can be transplanted, or 2) permanently replace a failed heart.

31. Use of a Left Ventricular Assist Device as a Bridge to Transplantation in a Pediatric Patient
Despite many advances in heart transplantation and in mechanical circulatory support, the benefits of staged cardiac transplantation have not been extended to the pediatric transplant recipient, chiefly because implantable circulatory assist devices are still too large. Extracorporeal devices, however, can overcome this impediment. Here we report the 1st cas

32. Studies of the Transferrin Receptor on both Human Reticulocytes and Nucleated Human Cells in Culture: COMPARISON OF FACTORS REGULATING RECEPTOR DENSITY
The transferrin receptor, present on reticulocytes and nucleated cells in tissue culture, has been measured with both immunoassay techniques and transferrin binding studies. The total cellular immunoreactive receptor is rapidly lost from erythrocytes during the process of reticulocyte maturation (from as many as 400,000 molecules to <20,000 molecules/reticul

33. Surgical Technique and Hemodynamic Characteristics of Partial Cardiac Replacement With an Artificial Left Ventricle
To evaluate a method of mechanical replacement of the left ventricle in patients with left ventricular failure, we used a single mechanical ventricle in experimental animals. Identical mechanical ventricles were placed in six Hereford calves to obtain data for partial replacement. Four of the animals were weaned from cardiopulmonary bypass, and the other two

34. Genetic loci of hemolysin production in Streptococcus faecalis subsp. zymogenes.
Two plasmids corresponding to molecular weights of 38.5 X 10(6) and 3.6 X 10(6) have been identified in Streptococcus faecalis subsp. zymogenes strain X-14. The larger plasmid is required for hemolysin-bacteriolysin production. Strain L2, a nonlytic nitrosoquanidine mutant of strain X-14, still harbors the hemolytic plasmid and produces the lysin component,

35. Late results of bulbar trigeminal tractotomy: Some remarks on recovery of sensibility
Re-examination of eight patients in whom bulbar trigeminal tractotomy had been performed 13 to 15 years previously showed that four had no complaints, and the other four had only very slight complaints about pain. In two patients a Spiller-Frazier operation had been performed after tractotomy, in two patients exairesis of the infraorbital or supraorbital ner

36. Roles of the Escherichia coli heat shock sigma factor 32 in early and late gene expression of bacteriophage T4.
We have analyzed early and late T4 gene expression at the levels of transcription and translation in rpoH+ (sigma 32+) and rpoH mutant cells infected under heat shock conditions. We found, as expected, that Escherichia coli cells must be adapted before infection to high temperature by the heat shock response to allow early T4 transcription, subsequent late g
