Reconstruction of Nasal Tip Using "Seagull-shaped" Cavum Concha Cartilage Composite Scaffold.

Background: The nasal tip plays a crucial role both esthetically and functionally. The application of nasal tip grafts is an effective method for improving nasal tip form. Ear cartilage is a common choice for nasal tip grafts, but it still presents several challenges in clinical application that need to be addressed.

Horizontally transferred genes in the genome of Pacific white shrimp, Litopenaeus vannamei.

Background: In recent years, as the development of next-generation sequencing technology, a growing number of genes have been reported as being horizontally transferred from prokaryotes to eukaryotes, most of them involving arthropods. As a member of the phylum Arthropoda, the Pacific white shrimp Litopenaeus vannamei has to adapt to the complex water environments with various symbiotic or parasitic microorganisms, which provide a platform for horizontal gene transfer (HGT).

Results: In this study, we analyzed the genome-wide HGT events in L.
