artemisinin extracted from artemisia annua l. is the best medicine with the highest efficiency, the most effective and the lowest toxicity in treating ague nowadays. at present, most studies focus on artemisinin and its derivatives, while the study and report about the other active components are rare. this paper purposed to further discover new indication of artemisia annua l. connecting with ...

background: there is controversy over the potential benefits/harms of the usage of angiotensin-converting enzyme inhibitors (aceis) or angiotensin receptor blockers (arbs) as regards the postoperative mortality of coronary artery bypass grafting (cabg). this study investigates the correlation between the in-hospital mortality of cabg and the preoperative administration of acei/arb. methods: out...

measurement of availability and mobility of heavy metals in river sediments is required in order to understand the behavior of these metals and to prevent potential toxic hazards. leaching column experiments were conducted for four sediment samples to determine the degree of mobility and the distribution of zn, cd, ni, cu, and pb because of an application of spiked heavy metals in sediments. se...

Flavonoids are potentially immunomodulatory factors and it may be inferred that these phytochemicals contribute to immunomodulatory properties of the Allium family. In the present study, we investigated the potential mechanism underlying the immunomodulatory effect of shallot and its ethyl acetate (EA) fraction as flavonoid-rich sources. Ex vivo, effects of a hydroalcoholic extract of shallot, ...

found we could duplicate the observed fraction of doublet craters found on Earth, Venus, and Mars. Our results suggest At least 10% (3 out of 28) of the largest known impact craters that any search for asteroid satellites should place emphasis on Earth and a similar fraction of all impact structures on on km-sized Earth-crossing asteroids with short-rotation Venus are doublets (i.e., have a com...

Between 2001 and 2003 the London Health Commission undertook health impact assessments (HIAs) on a series of strategies developed by the Greater London Authority and the Mayor of London. The HIAs were rapid, each involving a literature review and a participant workshop. In all cases the reports made a series of recommendations that were given to the Mayor. The HIAs led to changes and ensured th...
