Abstract:
A method for dynamic tracking of cardiac vulnerability to ventricular fibrillation is disclosed. A heart is monitored to sense an ECG signal (202) which is amplified (206) and low-pass filtered (208) before it is digitally sampled (210) and stored (212). The location of the T-wave in each R-R interval of the ECG is estimated and each T-wave is partitioned into a plurality of time divisions. The sampled ECG signal in each of the time divisions is summed together and a time series is formed for each of the time divisions such that each time series includes corresponding sums from corresponding time divisions from successive T-waves. Each time series is detrended in order to eliminate the effects of drift and DC bias, and then a method of dynamic estimation is performed on each time series to estimate the amplitude of alternation for each time division (214).

Abstract:
A method is described for the detection of antistreptokinase antibodies in a sample which comprises detection of a complex between lactate dehydrogenase, streptokinase, and antistreptokinase antibodies. The method is useful for the detection of antistreptokinase antibodies in the serum of patients prior to clinical streptokinase administration.

Abstract:
1a- and 7-substituted derivatives of mitosanes containing thiocarbamoyl and glycosyl residues. The compounds possess antibacterial and antitumor activity, with a concomitant reduction in bone marrow toxicity as compared to the parent compounds.
Abstract:
The polynucleotide sequence fragment conferring immunologic specificity to papillomavirus (PV) has been located and isolated. From this information, assays for type-specific PV, including DNA probes, RNA probes, immunoassays and the like are produced. The vaccines against specific PVs may be produced also. Further, the genus-specific amino acid sequence of the L1 capsid protein has been identified.
Abstract:
The non-linear conductance and capacitance characteristics of electrically non-homogeneous materials over a given frequency range are used to identify and analyze such materials.
Abstract:
A method for killing tumor cells in vivo entails providing replication competent herpes simplex virus vectors to tumor cells. A replication competent herpes simplex virus vector, with an essential herpes simplex virus gene which is driven by a tumor-specific or cell-specific promoter that specifically destroys tumor cells and is not neurovirulent. Also, a method for producing an animal model, by ablating a specific cell type in vivo, entails providing replication competent herpes simplex virus vectors to the animal. Such a vector, with an essential herpes simplex virus gene driven by a cell- or tissue-specific promoter, specifically destroys the target cell type. This method of viral-mediated gene therapy employs cell-specific viral replication, where viral replication and associated cytotoxicity are limited to a specific cell-type by the regulated expression of an essential immediate-early (IE) viral gene product.
Abstract:
A method for killing malignant brain tumor cells in vivo entails providing replication competent herpes simplex virus vectors to tumor cells. A replication competent herpes simplex virus vector, with defective expression of the gamma 34.5 gene and the ribonucleotide reductase gene, specifically destroys tumor cells, is hypersensitive to anti-viral agents, and yet is not neurovirulent.
