8 results about "Human thyroid" patented technology

A cricothyrotomy medical training device includes a ribbed tube representative of a human trachea, the ribbed tube having a first end and a second end. A first protrusion extends from the first end of the ribbed tube, the first protrusion being representative of a human thyroid cartilage. A second protrusion extends from the ribbed tube near the first end, the second protrusion being representative of a human cricoid cartilage. The second protrusion is longitudinally spaced between the first end and the second end. A first marking material is disposed at the first and second protrusions for representing a location of human skin. A second marking material disposed between the first and second protrusions to identify a location of a human cricothyroid membrane.

The invention relates to medical training aids. The claimed method includes preparing models of bone and cartilage structures and molds for blood vessel and thyroid models by 3D printing. A plastisol containing polyvinyl chloride is used for simulating a thyroid and blood vessels. This plastisol is poured into the molds for the blood vessel and thyroid models and held until it has cooled. A plastisol containing powdered graphite and a metal glitter for echogenicity is used for simulating lymph nodes and tumorous growths. Lengths of jute twine are laid in molds, into which a plastisol with added glitter is poured, the plastisol is held until it has cooled, and neck muscle models are cut out. A plastisol containing dyes is poured into a master neck mold to produce a skin model. The models of the muscles, vessels, thyroid, bone and cartilage structures, trachea, lymph nodes and tumorous growths are arranged in the master neck mold, into which a plastisol containing glitter is poured, the assembly is left to cool before being removed and the skin model is attached. The technical result is that the structure of the phantom more closely resembles the structure of a human thyroid.

The invention discloses a nucleic acid, a pharmaceutical composition containing the nucleic acid, a saRNA conjugate containing the nucleic acid, and a preparation method and application of the saRNA conjugate, and belongs to the technical field of biological medicines. The saRNA, the modified saRNA and the saRNA conjugate provided by the invention are combined with a promoter of a human thyroid hormone receptor beta (THRB) gene in a targeting manner, so that the expression of the THRB gene is activated. The saRNA, the modified saRNA and the saRNA conjugate provided by the invention have wide application prospects in the treatment application of the non-alcoholic fatty liver disease.

A chimeric protein comprising an extracellular domain of human thyroid-stimulating hormone receptor (TSHR), said domain lacking a C-terminal segment comprising at least the segment from amino acid residue 301 to 413 of TSHR.

On the basis of a Galpha s-cAMP-PKA signal channel, which plays a normal physiological role in vivo, of thyroid stimulating hormone and the regulation and control effect of the thyroid stimulating hormone on thyroid hormone synthesis, a normal human thyroid follicular epithelial cell line Nthy-ori 3-1 is transformed into a TSHR overexpressed stable cell line for the first time, the expression quantity of TSHR in a cell membrane is obviously increased, and the TSHR expression level is improved; the response sensitivity of the Nthy-ori 3-1 cell to a thyroid stimulating hormone drug is obviously improved; by detecting the synthesis level of cAMP and thyroid hormone before and after the stimulation of the thyroid stimulating hormone, it is verified that the TSHR overexpression Nthy-ori 3-1 cell line established in the research has great superiority for determining the biological activity of the human thyroid stimulating hormone.
