The present invention relates to methods for detecting sulfenylation within thiol groups in proteins, metabolites, or materials. Protein sulfenylation (Cys-SOH) describes the reversible post-translational modification of protein thiols by hydrogen peroxide, and plays a central role in oxidative signaling (see, e.g., Paulsen, C. E. & Carroll, K. S. 2013 Chemical Reviews 113, 4633-679). Growth factor stimulation activates NADPH oxidase enzymes, releasing a local burst of hydrogen peroxide, which transiently oxidizes the nuclcophilic cysteine of protein phosphatases and other proximal redox active thiols (see, e.g., Paulsen, C. E. et al., 2012 Nature Chemical Biology 8, 57-64). In addition to masking functional cysteine's, sulfenylation is also a critical intermediate towards irreversible cysteine oxidation. |

Methods and compositions for assessing germline risk of cancer
Heritable mutations in the BRCA1 and BRCA2 and other genes in the DNA double-strand break (DSB) repair pathway increase risk of breast, ovarian and other cancers. In response to DNA breaks, the proteins encoded by these genes bind to each other and are transported into the nucleus to form nuclear foci and initiate homologous recombination. Flow cytometry-based functional variant analyses (FVAs) were developed to determine whether variants in BRCA1 or other DSB repair genes disrupted the binding of BRCA1 to its protein partners, the phosphorylation of p53 or the transport of the BRCA1complex to the nucleus in response to DNA damage. Each of these assays distinguished high-risk BRCA1 mutations from low-risk BRCA1 controls. Mutations in other DSB repair pathway genes produced molecular phenocopies with these assays. FVA assays may represent an adjunct to sequencing for categorizing VUS or may represent a stand-alone measure for assessing breast cancer risk. |

Miniaturized Fourier-transform Raman spectrometer systems and methods
State-of-the-art portable Raman spectrometers use discrete free-space optical components that must be aligned well and that don't tolerate vibrations well. Conversely, the inventive spectrometers are made with monolithic photonic integration to fabricate some or all optical components on one or more planar substrates. Photonic integration enables dense integration of components, eliminates manual alignment and individual component assembly, and yields superior mechanical stability and resistance to shock or vibration. These features make inventive spectrometers especially suitable for use in high-performance portable or wearable sensors. They also yield significant performance advantages, including a large (e.g., 10,000-fold) increase in Raman scattering efficiency resulting from on-chip interaction of the tightly localized optical mode and the analyte and a large enhancement in spectral resolution and sensitivity resulting from the integration of an on-chip Fourier-transform spectrometer. |

In situ combustion for steam recovery infill
Methods and systems produce petroleum products from a formation by a steam assisted process followed by an in situ combustion process. The steam assisted process utilizes an injector and first producer to form a steam chamber within the formation as the products are recovered. The in situ combustion then starts by injecting an oxidant into the formation and ignition of residual products. A combustion front advances toward a second producer that may be offset in a lateral direction from the first producer. Heat and pressure from the in situ combustion sweeps the products ahead of the combustion front to the second producer for recovery. |

Modified polylactic acid fibers
A method for forming biodegradable fibers is provided. The method includes blending polylactic acid with a polyepoxide modifier to form a thermoplastic composition, extruding the thermoplastic composition through a die, and thereafter passing the extruded composition through a die to form a fiber.

The reaction-induced branching can also increase molecular weight, which may lead to improved fiber ductility and the ability to better dissipate energy when subjected to an elongation force. Through selective control over this method, the present inventors have discovered that the resulting fibers may exhibit good mechanical properties, both during and after melt spinning. |

Elastomeric compositions and their applications
A room temperature curable composition is disclosed. The composition can be used as an encapsulation/potting material. The composition comprises: (i) at least one condensation curable silyl terminated polymer having at least one silicon bonded hydroxyl functional group per molecule; (ii) a cross-linker having at least two hydrolysable groups and selected from certain silanes and/or silyl functional molecules; and (iii) a condensation catalyst selected from the group of titanates and/or zirconates. The molar ratio of the sum of moisture present in the composition and total silicon bonded hydroxyl groups:the catalyst (“the molar ratio”) is >7:1. When the molar ratio is from >7:1 to 10:1, the molar ratio of total silicon bonded hydroxyl groups:total hydrolysable groups is between 0.1:1 to 0.3:1. When the molar ratio is >10:1, the molar ratio of total silicon bonded hydroxyl groups:total hydrolysable groups is between 0.1:1 to 0.5:1. |

Perfluorinated ionomer nanoparticle dispersion solution, and preparation method therefor
Disclosed are: an ionomer nanoparticle dispersion solution formed by dispersing a perfluorinated ionomer having an ion conductive functional group in a solvent mixture including water and an alcohol, and carrying out a reaction under a supercritical condition; and a preparation method thereof. The ionomer nanoparticle dispersion solution has a high azeotropic mixture content in a continuous phase, which is a liquid phase, so as to readily remove a solvent therefrom, and thus a product using the ionomer nanoparticle dispersion solution can be readily fabricated and preparation costs can be reduced. In addition, uniformity of the product is improved because a perfluorinated ionomer having various ion conductive functional groups and various salts thereof is nano-dispersed, in a narrow molecular weight distribution, in the ionomer nanoparticle dispersion solution. |

Solution polymerized styrene-butadiene rubber-polyurethane elastomer material for high performance tire and preparation method thereof
A solution polymerized styrene-butadiene rubber-polyurethane elastomer material and a preparation method thereof are provided. The elastomer material is prepared by performing cast molding on a soft segment and a hard segment in a mass ratio of 100:(20-50); the soft segment includes hydroxyl-terminated solution polymerized styrene-butadiene moiety rubber prepared by an anionic polymerization; the hard segment comprises isocyanate, a small-molecule polyol chain extender and a cross-linking agent; and the soft segment has a molecular weight of 1000-8000 and a glass-transition temperature of −20° C. to −30° C. According to the elastomer material in the disclosure, the hydroxyl-terminated solution polymerized styrene-butadiene rubber is introduced to serve as the soft segment on the basis of synthesis of the traditional polyurethane elastomer, so that the glass-transition temperature of the polyurethane elastomer is regulated, defects such as poor high temperature resistance and undesirable wet-skid resistant grip ability of an existing polyurethane tire are overcome. |

Latex composition for dip molding, and molded product manufactured therefrom
The present invention relates to a latex composition for dip-molding comprising a mixture of latex pigment and carboxylic acid-modified nitrile based copolymer latex which are two types of latex having Tg different to each other, and a dip-molded article produced therefrom.The dip-molded article according to the present invention does not use sulfur and a vulcanization accelerator and thus has a low risk of allergies and can have excellent elasticity, while maintaining the physical properties such as tensile strength and modulus in the trade-off relationship opposite to each other at the levels equal to or higher than those of the prior art, so that the dip-molded article can be easily applied to industries in need thereof, such as industry of rubber gloves, etc. |
