Abstract: An ultra-high temperature fracturing fluid, including the following components in mass percentages: 0.4 wt %-0.8 wt % of a polymer thickener, 0.015 wt %-0.02 wt % of a non-metallic crosslinking agent, 0.04 wt %-0.06 wt % of a gel breaker and the rest is water. The polymer thickener is obtained by a polymerization of acrylamide, acrylic acid, 2-acrylamido-2-methylpropanesulfonic acid, rigid monomer and cationic hydrophobic monomer in a weight ratio of 55-70:15-20:15-20:0.5-3:0.1-1.0, the polymerization temperature is 30-40° C. and the polymerization time is 8-10 hours. The fracturing fluid of the present invention can effectively solve the technical problems that traditional fracturing fluids are easily decomposed at high temperatures and affect performance.
Abstract: The titanium plating solution production method including measuring a titanium plating solution containing fluorine and titanium by cyclic voltammetry under the following conditions, and adding titanium to the titanium plating solution so that the potential difference between the spontaneous potential and the Ti3+/Ti4+ redox potential is 0.75 V or more. Conditions: when the temperature of the titanium plating solution is 650° C. to 850° C. and when glassy carbon is used as a working electrode, platinum is used as a pseudo-reference electrode and titanium is used as a counter electrode, the potential scanning is repeatedly performed on the working electrode for at least five times at a scanning speed of 1 mV/sec to 500 mV/sec between a lower potential limit which is the immersion potential of the working electrode and an upper potential limit which is a potential that is 2 V to 4 V higher than the lower potential limit.

Abstract: The transmembrane metalloproteinase-disintegrin ADAM8 mediates cell adhesion and shedding of ligands, receptors, and extracellular matrix components. ADAM8 is abundantly expressed in breast tumors and derived metastases compared to normal tissue, especially in triple-negative breast cancers (TNBCs). High ADAM8 levels predicted poor patient outcome, and ADAM8 promoted an aggressive phenotype of TNBC cells in culture. Tumors derived from TNBC cells with ADAM8 knockdown failed to grow beyond a palpable size and displayed poor vascularization. Circulating tumor cells and brain metastases were also significantly reduced. ADAM8 stimulated angiogenesis through release of VEGF-A and cell migration through ?1-integrin activation. Treatment with anti-ADAM8 antibody in vivo resulted in reduced primary tumor burden and reduced metastases. Furthermore, antibody treatment of established tumors profoundly decreased metastases in a resection model.
Abstract: Methods, tip assemblies and kits are provided for introducing material into cells. The tip assemblies include an attachment portion, a channel portion, and a constriction that function to reduce fluid pressure as a fluid passes through the constriction portion from the channel portion, whereby the tip assemblies form pores in the membranes of cells and introduce material into the cells. The material includes for example one selected from the group of: an inorganic compound, a drug, a genetic material, a protein, a carbohydrate, a synthetic polymer, and a pharmaceutical composition.

Abstract: Embodiments of the present invention relate to a novel approach to automatically detect the occurrence of evoked potentials, quantify the attributes of the signal and visualize the effect across a high number of spinal cord epidural stimulation parameters. This new method is designed to automate the current process for performing this task that has been accomplished manually by data analysts through observation of the raw EMG signals, which is laborious and time-consuming as well as being prone to human errors. The proposed method provides fast and accurate framework for activation detection and visualization of the results within five main algorithms.
