the current study highlights the in vitro antioxidant and antitumor activity of the previously-synthesized hydrazone derivatives against various free radicals and human cancer cell lines, respectively. the anticancer efficacies of the compound were tested by measuring cytotoxicity in cancer cell lines hela, a549, and non-cancerous nl20 cells. compounds possessing electron-donor methoxy and meth...

Background: Three types of cell lines have been established from mouse blastocysts: embryonic stem (ES) cells, trophoblast stem (TS) cells, and extra-embryonic endoderm (XEN) cells, which have the potential to differentiate into their respective cognate lineages. ES cells can differentiate in vitro not only into somatic cell lineages but into extra-embryonic lineages, including trophectoderm an...

The present study was carried out to determine the free radical scavenging properties of some plants, found in Malaysia. The air-dried leaves of each plant (20 g) were soaked in distilled water (1:20; w/v) for 72 h at room temperature. Collected supernatants were tested for free radical scavenging activity against the DPPH and superoxide anion radical scavenging assays. All extracts were found ...

introduction: different dosimetric modalities (e.g., ionization chambers, semiconductors, tlds, radiographic films) often have some problems determining isodose curves and percentage depth doses in high dose gradient regions. research has been ongoing to develop portable high resolution dosimetry devices with accurate absolute dosimetry capabilities and easy data analysis. the ‘presage’ dosimet...

Background & Aim: Chorisia is an important Bombacaceous plant that is traditionally used for a variety of ailments. Due to its richness in several bioactive phytocompounds, some Chorisia species showed a wide range of important biological effects. Accordingly, the present work was undertaken to comparatively evaluate the antioxidant potential and effects on adipogenesis of <em...

Free radicals involved in a number of diseases due to the oxidative damage to DNA, lipids, and proteins and which can result in failure of cellular functions. Dried plant bulbs and leaves methanolic and ethanolic extracts were prepared. Total antioxidant activities of the methanolic extracts of Romulea ramiflora and Gagea fibrosa were determined using β-caroten-linoleic acid assay. Romulea-...
