| 24,25-epoxysterols. differentiation of 24r and 24s epimers by 13c nuclear magnetic resonance spectroscopy. | the 24r and 24s epimers of the acetates of 24,25-epoxycholesterol and 24,25-epoxylanosterol have been prepared and purified by preparative normal phase high performance liquid chromatography. neither pair of epimers could be differentiated by 1h nmr. however, the 13c nmr spectra of the epimeric pairs were sufficiently different to permit samples of individual epimers to be assigned as 24r or 24s. | 2010 | 2918248 |
| dose measurements in photodynamic therapy of cancer. | a theory and method for prediction and measurement of the effective absorbed dose in photodynamic therapy of cancer is presented. the method depends on measuring the concentration of the photosensitizer (such as dihematorporphyrin ether), the flux density of the light, and the relative photodynamic effectiveness. previous, less exact methods relied on specifying the drug dosage and delay after injection and or the irradiance at the surface or power from an interstitial fiber. the new formulation ... | 2010 | 2952849 |

| a syngeneic mlr induced in vivo results in t-cell mediated immune suppression. | the proliferation of murine t lymphocytes in response to syngeneic ia bearing non-t cells (syngeneic mixed lymphocyte reaction, smlr) has been shown to generate regulatory t cells in vitro. an in vivo regulatory role has therefore been proposed for the smlr. to study this role more directly, we examined the effects of repeated iv injection of mice with activated syngeneic b cells. three such weekly injections induced a suppression of the plaque forming cell response to a subsequent injection of ... | 2010 | 2952287 |
