Publication number: 20190284636Abstract: Ratio of neutrophils to lymphocytes (NLR) is here associated with immune suppression and decreased survival times in multiple solid tumors. Based on immune cell-specific DMRs and validated cell deconvolution algorithms, the NLR in blood from glioma patients was estimated and glioma patients had elevated mdNLR scores compared to controls. The patient mdNLR scores were increased in patients with grade IV tumors compared to grade II/III. High mdNLR scores were associated with shorter survival. Candidate single (myeloid-associated) gene loci that were highly correlated with the mdNLR were identified. Single myeloid differentiation loci provide a simpler and cheaper alternative to the mdNLR, which requires complex array data. Immunomethylomics are useful and more convenient than conventional cell analysis in profiling glioma risk and survival.Type: ApplicationFiled: October 26, 2017Publication date: September 19, 2019Applicants: BROWN UNIVERSITY, THE REGENTS OF THE UNIVERSITY OF CALIFORNIA, UNIVERSITY OF KANSAS, THE TRUSTEES OF DARTMOUTH COLLEGEInventors: Karl Kelsey, John Wiencke, Devin Koestler, Brock Christensen

Patent number: 10417187Abstract: In embodiments, secure compression algorithms are provided that may be employed as a single operation on raw data to produce compressed and encrypted data. In embodiments, the algorithms described herein may be performed using any type of dictionary based encryption. In one embodiment, upon adding a new prefix to a dictionary table, the dictionary table may be permuted to randomize the entries into the table. The randomization may be based upon a permutation value generated by a deterministic pseudo-random generator and/or pseudo-random function. Other embodiments of randomization may be employed to provide secure compression. For example, instead of permuting the entire table upon adding a prefix, the prefix may be randomly added to the table.Type: GrantFiled: June 3, 2014Date of Patent: September 17, 2019Assignee: Brown UniversityInventors: James Kelley, Roberto Tamassia

Patent number: 10339706Abstract: A system and method of estimating the body shape of an individual from input data such as images or range maps. The body may appear in one or more poses captured at different times and a consistent body shape is computed for all poses. The body may appear in minimal tight-fitting clothing or in normal clothing wherein the described method produces an estimate of the body shape under the clothing. Clothed or bare regions of the body are detected via image classification and the fitting method is adapted to treat each region differently. Body shapes are represented parametrically and are matched to other bodies based on shape similarity and other features. Standard measurements are extracted using parametric or non-parametric functions of body shape. The system components support many applications in body scanning, advertising, social networking, collaborative filtering and Internet clothing shopping.Type: GrantFiled: June 14, 2018Date of Patent: July 2, 2019Assignee: BROWN UNIVERSITYInventors: Michael J.

Patent number: 10307527Abstract: Systems, compositions, methods and kits employ protein shells, such as ferritin or viral capsid shells, herein called nanobubbles, to enhance X-ray images of cells or body tissue under certain x-ray imaging methods. The nanobubbles have sub-micron size such as about 10 nm, about 40, 60, or 100 nm and may be functionalized for effective delivery to or uptake by a target tissue, in vivo or a cell culture. The nanobubbles are hollow, having a central core which may be empty or contain a fluid, such that the shells effectively form long-lived bubbles in the imaged environment, and are of low electron density and have different scattering properties than the surrounding tissue. X-ray imaging by spatial frequency heterodyne imaging enhances visualization or detection of tissue regions bearing the shells. The protein shells may be further treated to assure biocompatibility and/or to resist undesired interactions with non-targeted tissue, such as scavenging by the liver, or attack by the immune system.Type: GrantFiled: April 21, 2015Date of Patent: June 4, 2019Assignees: Brown University, Montana State UniversityInventors: Christoph Rose-Petruck, Trevor Douglas, Danielle Rand, Masaki Uchida
