BACKGROUND The pine tip moth, Rhyacionia leptotubula (Lepidoptera: Tortricidae) is one of the most destructive forestry pests in Yunnan Province, China. Despite its importance, less is known regarding all aspects of this pest. Understanding the genetic information of it is essential for exploring the specific traits at the molecular level. Thus, we here(More)
The complete nucleotide sequence of the mitochondrial genome of the pine tip moth Rhyacionia leptotubula (Lepidoptera, Tortricidae) was determined. The entire genome is 15,877 bp in length, encoding the standard set of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and an A+T-rich control region. The gene order is typical of Lepidoptera and differs(More)
Bactrocera correcta (Diptera: Tephritidae) is one of the most serious pest insects in south China and surrounding Southeast Asian countries. The family Tephritidae includes over 4257 species distributed worldwide, so the complete mitochondrial genome would be helpful for bio-identification, biogeography and phylogeny. The B. correcta genome consists of 15(More)
A new catechin derivative named as sterilin A (1), and three known compounds, (+)-catechin (2), kaji-ichigoside F1 (3) and 2α,3α,19α-trihydroxyurs-12-en-28-oic acid-28-O-β-D-xylopyranosyl-(1 → 2)-β-D-glucopyranoside (4), was isolated from the fresh fruits of Rosa sterilis. Their structures were elucidated by means of extensive spectroscopic analysis and by(More)
The authors report their own experiences with the diagnosis and therapy of 7 cases of nasopharyngeal angiofibroma with extranasal and extrapharyngeal involvement, thereby attempt to formulate the surgical approach for resection of huge nasopharyngeal angiofibroma with extensive involvement. The results suggested that appropriate surgical approach was of(More)
OBJECTIVE To evaluate the efficacy of cartilage tympanoplasty in the treatment of adhesive otitis media. METHODS From June to October, 2008, 18 patients with adhesive otitis media (18 ears) were treated with tragus cartilage tympanoplasty. The air-bone gap changes and the self-perceived symptomatic improvement were evaluated at 1 month and 1 year after(More)
