This study examined the antioxidant and anticancer activities of the petroleum ether extracts from the roots of Platycodon grandiflorum A. DC, which is a plant used as both a herbal medicine and food in Asia. Extracts from Platycodon grandiflorum in petroleum ether were fractionated (fractions I-V) by silica gel column chromatography using gradient solvents (petroleum ether: ethyl ether, 9:1-5:...

PURPOSE To evaluate the roles of CB1 cannabinoid receptors in cellular functions of trabecular meshwork (TM) cells, including cell migration, adhesion, morphology and cytoskeleton changes. METHODS Noladin ether, a selective CB1 receptor agonist, and SR141716A, a selective CB1 receptor antagonist, were used to characterize the cellular functions of cultured porcine TM cells. Fluorescence assis...

The objective of this study was to investigate the aquatic-toxic effects of glyoxal-containing cellulose ether with four different glyoxal concentrations (0%, 1.4%, 2.3%, and 6.3%) in response to global chemical regulations, e.g., European Union Classification, Labeling and Packaging (EU CLP). Toxicity tests of glyoxal-containing cellulose ether on 11 different microbial strains, Microcystis ae...

Cholesterol and ether lipids are ubiquitous in mammalian cell membranes, and their interactions are crucial in ether lipid mediated cholesterol trafficking. We report on cholesterol's molecular interactions with ether lipids as determined using a combination of small-angle neutron and X-ray scattering, and all-atom molecular dynamics (MD) simulations. A scattering density profile model for an e...

ETHER has long been known to cause a short period of analgesia before inducing unconsciousness and surgical anesthesia. In 1794, Thomas Beddoes had already provided relief with a short inhalation of ether for a young woman suffering from a painful mastitis John Snow also alluded to that initial analgesic stage in his 1847 book on ether. Deep anesthesia was rarely sought or reached in the early ...

Sleep alterations after a 1-min exposure to ether vapor were studied in rats to determine if this stressor increases rapid eye-movement (REM) sleep as does an immobilization stressor. Ether exposure before light onset or dark onset was followed by significant increases in REM sleep starting approximately 3-4 h later and lasting for several hours. Non-REM (NREM) sleep and electroencephalographic...

The ether-lipid precursor sn-1-O-hexadecylglycerol (HG) can be used to compensate for early metabolic defects in ether-lipid biosynthesis. To investigate a possible metabolic link between ether-linked phospholipids and the rest of the cellular lipidome, we incubated HEp-2 cells with HG. Mass spectrometry analysis revealed major changes in the lipidome of HG-treated cells compared to that of unt...

the entomopathogenic fungus beauveria bassiana (bals.) vuill. is one of the important arthropod pathogens that can play an important role in the regulation of mite populations in agricultural ecosystems. in this study, the combined effect of a native isolate of fungus b. bassiana (eut105) and ether-extract of plant, ginkgo biloba was evaluated against the two-spotted spider mite, tetranychus ur...

the do1(18c6)fi (mwli. na. k and i 8c6=18-crown-6) complexes have been chosen as the model systems toinvestigate the nature of chemical bonds between alkali metal cations and large mffitidentaie orgmnic ligands.the b3lyp/6-3i+g(d,p) level of calculation has been used for obtaining equilibrium geernetnes and p(r)functions (electron density distributions). by the aid of fundamental physical theor...
