Abstract: This invention provides a method for preparing electrospraying particles to improve stability of polyphenol including the following steps: preparing a pectin-silica composite; adding polyphenolic compounds into the pectin-silica composite to prepare a core solution; and coaxial electrospraying the core solution and a shell solution to prepare electrospraying particles loaded polyphenol. This method utilizes a pectin-silica composite as a polyphenol loading carrier, improves the encapsulating efficiency of polyphenols, reduces the contact probability of polyphenols with oxygen and water, and improves the stability of polyphenols; and an acidic aqueous solution is used as a shell solution to synergize with the pectin-silica composite to further improve the stability of polyphenols.

Abstract: The present disclosure discloses use of combined inhibition of LncRNA SAMMSON and BRAF kinase for delaying adaptive drug-resistance of melanoma. The present disclosure reveals that the RAF/MEK/ERK kinase can rapidly up-regulate the RNA level of LncRNA SAMMSON in BRAF-mutated melanoma cells. Knocking down the SAMMSON can significantly facilitate the BRAF kinase inhibitor vemurafenib-induced apoptosis and increase the sensitivity of the cells to vemurafenib.

Abstract: The invention discloses a method for preparing a water-soluble phytosterol nano-dispersion system with intestinal targeted release function, which comprises the following steps: preparing a phytosterol solution; preparing an ethanol aqueous solution containing pectin; then adding zein to obtain a zein pectin solution; mixing the phytosterol solution and the zein pectin solution by means of ultrasonic treatment to obtain a nanoparticle dispersion liquid; rotavaping the nano-particle dispersion liquid to remove ethanol and water to obtain a zein/pectin loaded phytosterol nano-dispersion system. In this invention, not only an ultrasonic method and an anti-solvent method are adopted, but also a pectin component is added with zein as an entrapping agent, which ensures an effective entrapping of phytosterol by zein while further facilitating to form a more compact interface structure and improving a stability of the nano-dispersion system.

Abstract: In one embodiment, the inductor includes: a substrate, arranged with multiple lower conducting layers, a magnetic core, disposed on the substrate, and an insulating cover, covering the substrate and wrapping the magnetic core. Multiple upper conducting layers are arranged on a surface of the insulating cover. The upper conducting layers and the lower conducting layers are alternately connected to form at least one coil winding around the magnetic core. Two ends of the coil are respectively used to conduct external electrical signals.

Abstract: An illumination lamp is provided. The illumination lamp includes a hollow pillar tube being light-transmissive, at least one inner light tube accommodated in the hollow pillar tube, and an electrode set disposed at one distal end of the hollow pillar tube and electrically connected to the inner light tube in the hollow pillar tube.

Abstract: A saw for use with a blade coolant that includes a main body, a blade supported for rotation by the main body, and a drive member coupled to the blade and operable to rotate the blade. The saw further includes a coolant supply that is removably coupled to the main body and configured to store the blade coolant. A valve is coupled to the coolant supply, and the valve includes a valve member movable between an open position and a closed position. The valve member is held in the open position when the coolant supply is connected to the main body of the saw and the valve member is biased toward the closed position when the coolant supply is disconnected from the main body of the saw.

Abstract: The invention is a tamperproof electronic voting machine with intuitive user interfaces that is accessible and usable by voters with a wide range of disabilities, including those voters that are blind, deaf, blind deaf, or have dexterity disabilities. The voting machine preferably records votes through a button based interface or an ink probe interface. The invention accommodates cumulative voting and instant runoff voting.

Abstract: A light assembly is provided. The light assembly includes at least one ultraviolet (UV) lamp and a wavelength-converting member. The wavelength-converting member encircles the UV lamp and includes a substrate, and a wavelength-converting layer disposed on the substrate and faces the UV lamp. In this way, the wavelength-converting layer is energized by the ultraviolet light emitted from the UV lamp to emit a visible light in turn.

Abstract: The present invention is an ink-based electronic voting apparatus that generates a paper ballot for every voter. The voter marks a ballot with a probe as he/she would with a conventional ink-based system. In one embodiment, the paper ballot is situated underneath the surface of an input board electrically connected to a computer. A vote is cast when the probe is depressed onto the ballot at a designated input point. The electrical interaction between the probe and the input board generates a vote signal for recording and causes ink to be released from the probe to mark a corresponding spot on the paper ballot. As such, votes are electronically recorded for fast tabulation while paper ballots are generated for manual and/or optical scanner recounts to safeguard against computer errors and tampering. Furthermore the voting apparatus has a built-in mechanism to prevent undervoting and overvoting and thus increases valid votes.

Abstract: A card edge connector includes an insulating body having a central slot formed at a longitudinal direction thereof. A pair of locking devices is installed at both opposite distal ends of the insulator body and each locking device has a metal unit. The metal unit is formed by bending the first arm and the second arm upwards by the first arm. The second arm is placed outside the first arm and has a stop portion for limiting over-movement of the first arm. More space and material is saved because of its simple structure, convenient production, easy assembly and disassembly so as to enhance production efficiency.
