BACKGROUND The scapula locator method has associated intra-observer and inter-observer errors caused by the dependency on the observer to locate the scapular landmarks. The potential effect of the pressures applied by the observer on the measured scapular kinematics when this method is used has also been overlooked so far. The aim of this study was to… (More)
Chondrules in the metal-rich meteorites Hammadah al Hamra 237 and QUE 94411 have recorded highly energetic thermal events that resulted in complete vaporization of a dusty region of the solar nebula (dust/gas ratio of about 10 to 50 times solar). These chondrules formed under oxidizing conditions before condensation of iron-nickel metal, at temperatures… (More)
Introduction: The study of primitive carbonaceous chon-drites is an important means of understanding the conditions of the early Solar System. We report new data on the Antarctic find RBT 04133, originally classified as a CR2 carbonaceous chon-drite . However, we show that RBT 04133 is not a CR and has affinities to the CV and CO carbonaceous chondrite… (More)
The Open University's repository of research publications and other research outputs Secondary ion mass spectrometry and x-ray absorption near-edge structure spectroscopy of isotopically anomalous organic matter from CR1 chondrites GRO 95577 Conference Item (2007). Secondary ion mass spectrometry and x-ray absorption near-edge structure spectroscopy of… (More)
The anticancer drug, doxorubicin (DOX), was loaded onto DNA-capped gold nanoparticles (AuNP) designed for specific DOX intercalation. Drug binding was confirmed by monitoring DNA melting temperature, AuNP plasmon resonance maximum, and hydrodynamic radius increase, as a function of [DOX]/[DNA] ratio. The capacity for drug release to target DNA was confirmed.
Introduction: It has long been recognized that both the soluble (SOM) and insoluble (IOM) organic matter in primitive chondrites and IDPs contain organic material with large D and 15 N enrichments . In the SOM there are considerable isotopic variations amongst individual compounds within and between meteorites. Similarly, the IOM varies dramatically in… (More)
Introduction: Primitive chondrites are mineralogi-cally, chemically and isotopically unequilibrated. Isotopic anomalies are common for bulk chondrites and components within them [1-5]. There are multiple causes for the isotopic anomalies. For example, extremely large isotopic anomalies that deviate by orders of magnitude from solar ratios are present in… (More)
Introduction: The organic matter contained within carbonaceous chondritic meteorites has the potential to provide a unique perspective of chemical processes that occurred early in Solar System history. Recently, for example it was concluded that the significant chemical structural variation across Insoluble Organic Matter (IOM) isolates from four petrologic… (More)
