Abstract: Clinical management of human cancer is dependent on the accurate monitoring of residual and recurrent tumors. We have developed a method, called personalized analysis of rearranged ends (PARE), which can identify translocations in solid tumors. Analysis of four colorectal and two breast cancers revealed an average of nine rearranged sequences (range 4 to 15) per tumor. Polymerase chain reaction with primers spanning the breakpoints were able to detect mutant DNA molecules present at levels lower than 0.001% and readily identified mutated circulating DNA in patient plasma samples. This approach provides an exquisitely sensitive and broadly applicable approach for the development of personalized biomarkers to enhance the clinical management of cancer patients.

Abstract: A method executable via operation of configured processing circuitry to identify applications by remote monitoring may include initiating remote communication with a target device through an access point, the access point providing network access to the target device, providing a series of ping messages to the target device via the access point to determine a delay signature of an application running on the target device, and generating application identification information based on the delay signature.
Abstract: The present invention relates to the field of cancer. More specifically, the present invention relates to the use of biomarkers to detect colorectal cancer. In one aspect, the present invention provides methods for qualifying colorectal cancer status including, but not limited to, diagnosis, prognosis, and risk stratification, in patients. In one embodiment, a method for diagnosing colorectal cancer (CRC) in a patient comprises the steps of (a) collecting a sample from the patient; (b) measuring the methylation levels of one or more biomarkers in the sample collected from the patient; and (c) comparing the methylation levels of the one or more biomarkers with predefined methylation levels of the same biomarkers that correlate to a patient having CRC and predefined methylation levels of the same biomarkers that correlate to a patient not having CRC, wherein a correlation to one of the predefined methylation levels provides the diagnosis.

Abstract: Controlled release dosage formulations for the delivery of one or more HIF-1 inhibitors are provided. The controlled release formulations contain one or more HIF-1 inhibitors conjugated to or dispersed in a polymeric vehicle. The one or more HIF-1 inhibitors can be dispersed or encapsulated in a polymeric matrix. In some embodiments, the one or more HIF-1 inhibitors are covalently bound to a polymer, forming a polymer-drug conjugate. Polymeric vehicles can be formed into implants, microparticles, nanoparticles, or combinations thereof. Controlled release HIF-1 formulations provide prolonged therapeutic benefit while lowering side effects by releasing low levels of one or more HIF-1 inhibitors and/or HIF-1 inhibitor conjugates over a prolonged period of time. Controlled release dosage formulations can be used to treat or prevent a disease or disorder in a patient associated with vascularization, including cancer, obesity, and ocular diseases such as wet AMD.

The detector may further include an aerosol focuser configured to capture and focus the aerosol such that the aerosol is configured to be encapsulated within the droplet in order to cause the assay reagent to react in the droplet. The detector may even further include an interrogator configured to interrogate the droplet in order to detect the agent within the aerosol.
Abstract: A method of preserving a cell-free protein expression system includes preserving a cell extract with a first non-reducing sugar alcohol to provide a preserved cell extract, preserving a reaction buffer with a second non-reducing sugar alcohol to provide a preserved reaction buffer, and preserving an energy source, so that the cell extract, the reaction buffer, and the energy source are preserved separately.
Abstract: An embodiment in accordance with the present invention provides a method for applying task-based performance predictors (measures of noise, spatial resolution, and detectability index) based on numerical observer models and approximations to the local noise and spatial resolution properties of the CBCT reconstruction process (e.g., penalized-likelihood iterative reconstruction). These predictions are then used to identify projections views (i.e., points that will constitute the scan trajectory) that maximize task performance, beginning with the projection view that maximizes detectability, proceeding to the next-best view, and continuing in an (arbitrarily constrained) orbit that can be physically realized on advanced robotic C-arm platforms.

Abstract: A method for isolating a computer platform includes receiving a service request from an external requestor via a network at processing circuitry associated with a hardware barrier between the computer platform and the network, causing the service request to be loaded into a first buffer having a dual port connection to a corresponding second buffer of the computer platform, providing an indication to the computer platform to indicate the service request is loaded into the first buffer to be pulled into the second buffer of the computer platform, responsive to processing of the service request by the computer platform, receiving a message indicating a response loaded in the second buffer has been pushed to the first buffer, and communicating the response to the external requestor. The buffers form the only access point to the computer platform. The indication is the only communication initiated from the external requestor that crosses the hardware barrier without control by the computer platform.

Abstract: The invention provides methods and compositions for administration of allogeneic lymphocytes as an exogenous source of CD4+ T cell help for endogenous, tumor-reactive CD8+ T cells. Depletion of CD8+ T cells from the donor lymphocyte infusion reduces the risk of sustained engraftment and graft-versus-host disease. Removal of regulatory T cells from the infused population may augment the ability of non-regulatory T cells to provide help for endogenous effectors of anti-tumor immunity. Allogeneic T cell therapy is typically given in the context of allogeneic stem cell transplantation, in which the patient receives highly immunosuppressive conditioning followed by an infusion of a stem cell graft containing unselected populations of mature T cells. In the treatment described here, the graft is engineered to minimize the possibility of sustained donor cell engraftment, and the anti-tumor effector T cells derive from the host.

Abstract: A method for producing a spatially patterned structure includes forming a layer of a material on at least a portion of a substructure of the spatially patterned structure, forming a barrier layer of a flourinated material on the layer of material to provide an intermediate structure, and exposing the intermediate structure to at least one of a second material or radiation to cause at least one of a chemical change or a structural change to at least a portion of the intermediate structure. The barrier layer substantially protects the layer of the material from chemical and structural changes during the exposing. Substructures are produced according to this method.
Abstract: The prostate-specific membrane antigen (PSMA) is increasingly recognized as a viable target for imaging and therapy of cancer. Various 99mTc/Re-labeled compounds were prepared by attaching known Tc/Re chelating agents to an amino-functionalized PSMA inhibitor with or without a variable length linker moiety. Ex vivo biodistribution and in vivo imaging demonstrated the degree of specific binding to engineered PSMA+ PC3 PIP tumors.
