20120072988 | DETECTION OF GLOBAL METAMORPHIC MALWARE VARIANTS USING CONTROL AND DATA FLOW ANALYSIS - Malware feature extraction derives semantic summaries of executable malware using global, inter-procedural program analysis techniques. A combination of global, inter-procedural program analysis techniques constructs semantic summaries of malware which automatically detect and discard any noise introduced by transformations and capture the essence of the underlying computations in a succinct form. This is achieved in two ways. First, global control flow analysis techniques are used to derive a high level representation of malware code that, for instance, removes the effects of subroutine calls. Second, global data flow analysis techniques are employed to detect and remove all spurious elements of malware that do not contribute towards its underlying computation, thereby preventing the resulting summaries from being “corrupted” with unnecessary, extraneous elements. | 03-22-2012 |

20100216120 | Rapid infectious virus assay - An assay to detect or quantify HIV infectious virus from clinically relevant cellular compartments, or reservoirs, in anti-retrovirally treated patients whose viral levels are low to undetectable is described. The method detects infectious virus in patients whose plasma viral loads are considered to be below the limit of current PCR based detection methods and thereby is more relevant for guiding treatment. A further advantage is that the method allows viral tropism to be directly determined in the presence of specific inhibitors of CCR5 or CXCR4. Drug sensitivity can also be directly determined without the need to laboriously recover patient virus by culture for extended time periods, a method that allows for viral selection or evolution, which is not desirable. Patient cells, like the blood mononuclear cells, or monocytes, are isolated and cultured in the presence of cytokines like CSF-1/M-CSF or GM-CSF. to promote their differentiation. Cells are activated with lectins, mitogenic antibodies, phorbol esters, Toll Receptor stimulation or inducers of NfKb or NFAT, followed by agents that induce viral release, like ATP or stimulation of autophagy with LiCl, spermidine, or rapamycin. A key aspect of the invention relates to the timing of the addition of these agents for optimal viral release. A further aspect of the invention relates to sensitive detection of released virus which can be accomplished by adding so-called reporter cells which are under control of the HIV TAT protein so that upon infection these cells synthesize proteins or enzymes that allow for the measurement of infectious particles. | 08-26-2010 |
