The value of high-flow nasal cannula oxygen therapy in treating novel coronavirus pneumonia.

Objective: This study aimed to investigate the value of high-flow nasal cannula (HNFC) oxygen therapy in treating patients with severe novel coronavirus pneumonia (COVID-19).

Methods: The clinical data of 22 patients with severe COVID-19 were collected. The heart rate (HR), respiratory rate (RR) and oxygenation index (PO /FiO ) at 0, 6, 24 and 72 hours after treatment were compared between the HFNC oxygen therapy group and the conventional oxygen therapy (COT) group.

Internal transcribed spacer 2 (ITS2) barcodes: A useful tool for identifying Chinese .

Premise Of The Study: The genus in the Rutaceae family of trees and shrubs has a long history of domestication and cultivation in Asia for both economic and medicinal purposes. However, many species are morphologically similar and are easily confused. This often leads to false authentication of source materials and confusion in herbal markets, hindering their safe utilization and genetic resource conservation.

The complete chloroplast genome of an aromatic Chinese pepper ().

The Chinese pepper () is a flowering plant in the family Rutaceae, native to eastern China and Taiwan. Like many other members of the Rutaceae, it is an economically important aromatic crop known for its volatile oil and nutrition. We determined the complete chloroplast genome sequences for using IIumina sequencing.
