Abstract: There is provided a method of detecting and/or determining the presence of one or more thyroid-specific nucleic acid, the method comprising annealing the one or more thyroid-specific nucleic acid in the presence of a control nucleic acid, and subjecting each of the one or more thyroid-specific nucleic acid to one or more amplification step in the presence of a mixture comprising a surfactant and an oligonucleotide primer and/or probe capable of hybridizing with the one or more thyroid-specific nucleic acid, wherein the oligonucleotide primer and/or probe comprises a cleavage site and a cleavable 3? end. Also disclosed are methods of detecting and/or determining thyroid cancer recurrence and/or metastasis and thyroid-specific nucleic acid detection mixtures, and kits thereof.

Abstract: A drip irrigation emitter flow channel structural design method and a fractal flow channel drip irrigation emitter product therefor. The method comprehensively considers within a design process the hydraulic performance and anti-blocking performance of a drip irrigation emitter, and mainly comprises stages such as simulation method establishment, flow channel configuration selection, structural parameter determination and flow channel boundary optimization. An optimal flow channel configuration and a structural parameter value range of a drip irrigation emitter flow channel are determined via an optimal value simulation model, thereby defining a drip irrigation emitter primary prototype structural design method.
