The response of a novel long-period fiber grating (LPFG) with a period of 180 µm to a surrounding refractive index (RI) was investigated. The results displayed that, with the increase in RI of the surrounding media of cladding glass in the grating region, the resonant peak located at 1336.4 nm in the transmission spectrum gradually shifts towards a shorter(More)
OBJECTIVE To compare the effects of crude and wine-processed Rhei Radix et Rhizoma on upper-energizer disease and hepatic energy metabolism in mice. METHODS The streptococcal pneumonia rats model and acetic acid burning mouth ulcers rats model were established and randomly divided into three groups: model group, crude Rhei Radix et Rhizoma group and(More)
OBJECTIVE To analyze the differences of volatile components of medicinal materials from Perilla frutescens (Perillae Folium; Perillae Caulis; Perillae Fructus). METHODS The volatile components were identified by HSGC/MS. The relative percentage content of the components were determined by peak area normalization method and the content change of common(More)
1. The purpose of the present study was to investigate the effect of piperine (PP) on the pharmacokinetics of rosmarinic acid (RA) in rat plasma and to determine whether PP could enhance the oral bioavailability of RA via inhibition of its glucuronidation. 2. The pharmacokinetic profiles of RA between oral administration of RA (50 mg/kg) alone and in(More)
A mono-adenine-functionalized pillar[5]arene and a guest including uracil were prepared. They formed a novel four-unit [c2]daisy chain both in the solid state and in a chloroform solution. As far as we know, this [c2]daisy chain is the first one without a covalently bound linear thread. This unique assembly behavior is mainly induced by hydrogen-bond(More)
