Abstract: A clitoris shield has an oval body with a convex surface and a concave surface, a rectangular laser guide extending longitudinally from the oval body; and an arcuate laser guide extending radially from the convex surface. The clitoris shield is made of a material having a color that disperses, reflects, and/or blocks laser energy. The arcuate laser guard has a longitudinal axis parallel to the longitudinal axis of the oval body and the rectangular laser guide. The concave surface fits a clitoris. The clitoris shield prevents a woman from getting burned on her clitoris during laser hair removal, avoiding pain and permanent damage to the clitoris.

Abstract: The present disclosure relates to methods for selectively hydrogenating acetylene, to methods for starting up a selective hydrogenation reactor, and to hydrogenation catalysts useful in such methods. In one aspect, the disclosure provides a method for selectively hydrogenating acetylene, the method comprising contacting a catalyst composition with a process gas. The catalyst composition comprises a porous support, palladium, and one or more ionic liquids. The process gas includes ethylene, present in the process gas in an amount of at least 20 mol. %; acetylene, present in the process gas in an amount of at least 1 ppm; and 0 to 190 ppm or at least 600 ppm carbon monoxide. At least 90% of the acetylene present in the process gas is hydrogenated, and the selective hydrogenation is conducted without thermal runaway.

Abstract: The subject invention pertains to nucleic acid constructs for post-transcriptional control of expression of a polynucleotide encoding a protein in a cell, wherein the constructs include a metabolite responsive instability element such as the glucose-regulated mRNA instability element. The subject invention further pertains to host cells and vectors comprising the nucleic acid constructs of the invention, as well as probes, methods, and kits for detecting metabolite responsive instability elements or mutations thereof. The present invention further concerns a reporter vector useful for detecting intracellular glucose and glucose-analogs, host cells genetically modified with the reporter vector, and methods for detecting intracellular glucose. The present invention utilizes an element that regulates messenger RNA (mRNA) stability in response to a metabolite such as glucose or a glucose analog.
