Abstract: Provided are an apparatus for injecting a liquid into a primo-node and a primo-vascular system tracing system including the apparatus. The apparatus includes a liquid injection tube to inject a liquid into a primo-node of an object, and a suction tube to hold the primo-node to inject the liquid injection tube into the primo-node. The liquid injection tube and the suction tube are formed as one body. The liquid injection tube is inserted into an inner side of the suction tube and an edge unit of the liquid injection tube protrudes to the outside from an inner side of a suction opening of the suction tube.

Abstract: The present disclosure relates to a method of diagnosing metastatic cancer or taxane-based drug-resistant cancer, including: measuring an LMCD1 expression level from a complex formed by bringing, into contact with a sample isolated from a subject, an antibody, peptide, protein, or combination thereof that specifically binds to an LMCD1 protein or a fragment thereof; or a probe, primer, nucleotide, or combination thereof that specifically binds to a nucleotide sequence encoding the LMCD1 protein; and comparing the measured LMCD1 expression level of the sample with a measured LMCD1 expression level of a control, and a kit for diagnosing metastatic cancer or taxane-based drug-resistant cancer, including a composition for diagnosing metastatic cancer or taxane-based drug-resistant cancer.

Abstract: Example embodiments relate to a green-light emitting device including a quaternary quantum well on a vicinal c-plane. The light-emitting device includes a substrate having a vicinal c-plane surface and a light-emitting layer on the vicinal c-plane surface of the substrate. The light-emitting layer includes a quantum well layer of AlxInyGa1-x-yN and quantum barrier layers of InzGa1-zN disposed on and under the quantum well layer respectively, and 0<x<1, 0<y<1, and 0<z<1.
