Many chemical and physical systems can occur in two forms distinguished solely by being mirror images of each other. This phenomenon, known as chirality, is important in biochemistry, where reactions involving chiral molecules often require the participation of one specific

We have developed an electron spin resonance (ESR)-stopped flow technique and employed it for the simple and rapid determination of internal volumes of biomembrane vesicles and liposomes. A vesicle suspension containing a neutral and membrane-permeable spin label, 2,2,6,6-tetramethyl-4-oxopiperidine-1-oxyl (TEMPONE), was

Apoptosis of immature thymocyte of mice induced by dexamethasone and DNA strand-broken cells induced by K2Cr2O7 were tested by comet assay. The results showed that the morphology of apoptotic cells assayed by comet was special. Under the same condition, the
The radicals generated by adriamycin-sensitive (CHO-AB) and adriamycin-resistant (CHO-C5) Chinese hamster ovary cells as well as by adriamycin-sensitive and -resistant human breast cancer cells (MCF7-WT and MCF7-ADR) have been studied with spin-trapping and ESR spectroscopy. During anoxic exposure to adriamycin
