- Widespread species tend to have larger populations and better environmental adaptability, enabling them to expand their ranges, whereas narrow-range species are limited to specific areas and conditions.
- The study uses a species complex of wild rats in Southeast Asia and China to analyze the genomic differences between widespread and narrow-range species, finding that the former exhibit higher genetic diversity.
- The researchers identified 13 specific genes related to nervous system development that are shared among the widespread species, suggesting these genes are important for their adaptive evolution and speciation.
Article Synopsis
- Many plants, particularly Gaoben, hold significant medicinal and economic value and are used in traditional Chinese medicine for various treatments.
- The study focused on the complete chloroplast genome sequences of three Gaoben-related species, revealing that they have similar structures and are challenging to distinguish using standard DNA barcoding methods.
- The research identified specific DNA barcodes and suggested phylogenetic revisions for these genera, contributing valuable data for future identification and study of medicinal plants in the Apiaceae family.
Objective: To investigate the feasibility of vestibulotomy above the displaced facial nerve.
Methods: From January 2000 to January 2002, eight patients with severe congenital conductive hearing loss underwent the vestibulotomy above displaced facial nerve and reconstruction of the ossicular chain with a total ossicular replacement prosthesis, which all for the congenital middle ear deformity and the facial nerve overhang and concealed the oval window niche or lied inferior to the oval window. In four of eight cases, the facial nerve was transposed in order to access the oval window niche.
