Methods of detecting insulator dysfunction and oncogene activation for screening, diagnosis and treatment of patients in need thereof
The present application generally to the diagnosis and treatment of diseases resulting from the alteration of chromatin boundaries between topologically-associated domains. In particular, the present application relates to detection of mutations causing DNA hypermethylation phenotypes, CpG methylation within CTCF binding motifs, and aberrant gene expression caused by altered chromatin topology. Applicants show that IDH mutant gliomas exhibit hyper-methylation at CTCF binding sites, compromising binding of this methylation-sensitive insulator protein. Applicants also demonstrate that loss of CTCF at a domain boundary permits a constitutive enhancer to aberrantly interact with the receptor tyrosine kinase gene PDGFRA, a prominent glioma oncogene. Thus, Applicants have uncovered that IDH mutations may promote gliomagenesis by disrupting chromosomal topology and allowing aberrant regulatory interactions that induce oncogene expression. |

The object of this invention is a process for manufacturing, conditioning and stabilization of a family of base additives sodium, potassium, boron, silicon, zinc, calcium oxides, among others, prepared by physicochemical and chemical synthesis methods that form nanometric structures, reformulated with deflocculant, sequestrants and dispersants additives that allow to obtain a dispersion or powder capable to decrease the sintering temperature of a ceramic body due to the high fluxing power, which is maximized by the use of nanotechnology in the structures obtained. The process consists in the preparation of nucleation seeds of metal, silicates and carbonates oxides by means of a physicochemical process, and which allow nanometric structures to grow by means of a chemical process in a chemical synthesis process wet basis of sodium, boron, silicon, zinc, potassium and calcium oxides. The combination of these oxides allows structuring elements of high fluxing power due to their high surface area and physicochemical composition. The additives prepared in this invention are chemically stabilized with deflocculating agents, which allow the additives to be incorporated into the aqueous medium grinding process of the ceramic body. Applications made with the additives of this invention allow the sintering temperature of a red body to be reduced from 1150° C. to 1000° C. and in porcelain bodies from 1180° C. to 1050° C., with the use of 0.2 to 5% of the additive, or increasing the speed of the heat treatment by up to 20%, and it can be used in the manufacture of bathroom fittings, molding parts, components for tooling, coatings, valances, enamels, vitrified pastes and other ceramic components. The present invention proposes several nanostructured additive formulations with high performance fluxing properties, which allow to optimize and standardize the sintering process and to improve the mechanical properties of the ceramic body. It also proposes different methods of application of the additive in ceramic formulations. |

Control device for hybrid vehicle
Since a maximum rotation speed is set to a lower value when a supercharging pressure from a supercharger is high than when the supercharging pressure is low, an engine torque is decreased at a relatively low engine rotation speed and the engine rotation speed is less likely to fall into a high-rotation state. Since the maximum rotation speed is set to a relatively high value when the supercharging pressure is relatively low and the engine rotation speed is less likely to fall into a high-rotation state, the engine torque is not decreased at a relatively high engine rotation speed and power performance can be easily secured. Accordingly, it is possible to curb a decrease in power performance due to a decrease in the engine torque and to prevent the engine rotation speed from falling into a high-rotation state. |

The sacrificial component can include oxidizing agents such as chlorates, perchlorates, nitrates, dichromates, nitramides, and/or sulfates imbedded in a polymeric matrix, and the oxidizing agents can be 30 wt. % to 80 wt. % of the sacrificial component. The sacrificial component can further include one or more of unoxidized metal powder fuels, flammable gas-filled polymeric bubbles, one or more metallocenes and/or one or more metal oxide particles, one or more polymers with nitroester, nitro, azido, and/or nitramine functional groups, one or more burn rate suppressants such as oxamide, ammonium sulphate, calcium carbonate, calcium phosphate, and ammonium chloride, and non-combustible hollow bubbles and/or inert particles. The polymeric matrix can have a limiting oxygen index of less than about 30. |
