Hypoxia-inducible factor-1 (HIF-1) is an important tumor-selective therapeutic target for solid tumors. Icariside II was isolated from Epimedium koreanum through successive fractionation with ethyl acetate, n-butanol, chloroform and hexane, followed by gel column chromatography. Icariside II
Dry ethyl acetate extract containing flavonoids was obtained from above-ground parts of Astragalus corniculatus Bieb. Seven flavonoids were isolated and identified as rutin, hyperoside, isoquercitrin, narcissin, quercetin, kaempferol and isorhamnetin for the first time. The extract was found to be
BACKGROUND
Rhododendron anthopogonoides Maxim, a kind of traditional Tibetan medicine, has been used to remove body heat, body detoxification, cough, asthma, stomachic and swelling, eliminate abundant phlegm and inflammatory for a long time. In the present study, the total phenols and total
Experiments were carried out to study the resistance of rats to an acute effect of ethylacetate vapors at concentrations of 25 to 69 g/m-3 after their 20-day exposure to hypokinesia and 20-day exposure to altitudes of 3200 and 5000 m. The effect of ethylacetate at concentrations of 47 and 10 mg/m-3
In cancer treatment, herbal medicines may be a good choice because of the reduced risk of adverse side effects. Artemisia capillaris has been recognized as a promising candidate due to its hepatoprotective effects. Herein, we investigated whether A. capillaris-derived fraction (ACE-63) could inhibit
Spermacoce hispida (S.hispida), a potential medicinal plant has been traditionally used as an antibacterial, antieczemic, antihypertensive, antidiabetic and antihyperlipidemic agent. Although, this plant has been claimed to protect against oxidative injury and inflammatory conditions Biodegradation of nitroglycerin (NG), an inhibitory, nongrowth substrate present in a multicomponent munition wastewater, was investigated in a pilot-scale batch reactor operated with both aerobic and anoxic cycles. A mixed culture was initially acclimated by gradual introduction of NG into influent
Arachnocampa larvae utilise bioluminescence to lure small arthropod prey into their web-like silk snares. The luciferin-luciferase light-producing reaction occurs in a specialised light organ composed of Malpighian tubule cells in association with a tracheal mass. The accepted model for
Recent evidence indicates that hypoxia-inducible vascular endothelial growth factor (VEGF) has neurotrophic and neuroprotective effects on neuronal and glial cells. On the other hand, recent epidemiological studies showed that daily coffee consumption has been associated with a lower risk of several
OBJECTIVE
To study the effect of Blackcurrant on human umbilical vein endothelial ECV-304 cells injury induced by hydrogen peroxide (H2O2).
METHODS
The H2O2 damaged model was established. The effect of Blackcurrant on injury of ECV-304 activity induced by H2O2 was determined by MTT assay. The levels
BACKGROUND
Rhodiola algida, Saussurea involucrata, and other herbs grown in Qinghai-Tibetan plateau have long been used to prevent and treat acute mountain sickness.
OBJECTIVE
To screen and identify the anti-hypoxic constituents in the herbs grown in Qinghai-Tibetan plateau of Northwestern
