The apoptotic effect of sarsasapogenin from Anemarrhena asphodeloides on HepG2 human hepatoma cells.
Sarsasapogenin, a kind of mainly effective components of Anemarrhena asphodeloides Bunge (Liliaceae) has the effects of being anti-diabetes and improving memory. However, there are few reports focusing on its anti-tumor effects. In this study, the sarsasapogenin was extracted from rhizomes of A. asphodeloides Bunge and applied to inhibit HepG2 human hepatoma cells. MTT assay showed that sarsasa...
Relativistic wave functions for elements with Z = 37-54 [Su & Coppens (1998). Acta Cryst. A54, 646-652] have been fitted with a linear combination of Slater-type functions as defined by Bunge, Barrientos & Bunge [At. Data Nucl. Data Tables (1993), 53, 113-162], for use in charge-density analysis and other applications. In addition, numerical relativistic wave functions have been calculated for ...
گونه a. hotkanensis massoumi & mirtadzadini به عنوان گونه جدید متعلق به بخش microphysaاز کرمان معرفی می گردد. گونه جدید با محور برگی بلند، برگچه های واژ تخم مرغی با نوک تخت یا اندکی شیاردار، با گلاذین کم گل و اندکی واژگون و همچنین با کاسه بزرگ که نیمه فوقانی آن برنگ قرمز می باشد از کلیه گونه های خویشاوند جدا می گردد. این گونه با a. meimandicus maassoumi & vakili و a. reuterinanus bunge...
Three kinds of polyphenols of Salvia miltiorrhiza Bunge, 3,4-dihydroxyphenyllactic acid, salvianolic acid B and protocatechualdehyde, were separated and purified in one step with solvent system n-hexane-ethyl acetate-methanol-acetic acid-water (1:6:1.5:1.5:8) by high-speed counter-current chromatography. Acetic acid was successfully used to increase the partition of high polar target compounds ...
In response to constant criticism that methods for conceptual modeling in information systems lack theoretical foundations, several approaches have been proposed. Among these, ontological approaches have recently received considerable attention. Though MCCARTHY and HAYES already in 1969 had called for ‘‘metaphysically adequate modeling,’’ it was not before 1986 that WAND and WEBER commenced wor...
Until relatively recently, we thought that the human central nervous system (CNS) was unable to regenerate. However, with the initial discovery of remyelination within the brain and the spinal cord in cat (Bunge, Bunge and Ris. Ultrastructural study of remyelination in an experimental lesion in adult cat spinal cord. J Biophys Biochem Cytol 1961;10:67-94.) and later in human (Prineas and Connel...
Astragalus mongholicus Bunge has long been used to treat cardiovascular disease in Chinese traditional medicine. However, its mechanisms are not fully understood. In this study, we explored potential mechanisms and protective effects of total flavonoids of Astragalus (TFA) on cardiovascular disease using in vitro experiments and diet-induced atherosclerotic rabbits. We identified six components...
