Hollander JM, Thapa D, Shepherd DL. Physiological and structural differences in spatially distinct subpopulations of cardiac mitochondria: influence of cardiac pathologies. Am J Physiol Heart Circ Physiol 307: H1–H14, 2014. First published April 28, 2014; doi:10.1152/ajpheart.00747.2013.—Cardiac tissue contains discrete pools of mitochondria that are characterized by their subcellular spatial a...

The Abeta peptide is the major protein component of amyloid deposits in Alzheimer's disease (AD). Age-related microenvironmental changes in the AD brain promote amyloid formation that leads to cell injury and death. Altered levels of metals (such as Cu and Zn) exist in the AD brain, and because Cu and Zn can be bound to the Abeta in the amyloid plaques, it is thought that these binding events i...

In the present study, platinum nanoparticles were synthesized through an effective, facile and green method using H14[NaP5W30O110], a Preyssler-structured polyoxometalate, under UV light irradiation. Preyssler plays the roles of photocatalyst, reducing agent and stabilizer in the synthesis of Pt nanoparticles. The effect of different parameters, i.e. time, propan-2-ol volume, pH, molar ratio of...

E nveloped viruses acquire a lipid membrane when they bud across a cellular membrane during virus assembly. In cell entry, the viral membrane must be fused to the host-cell membrane to deliver the viral genome into the cytoplasm for replication. Membrane fusion is therefore an essential step in the life cycle of enveloped viruses, and a great deal of research in recent years has been directed a...

Recent technological improvements have extended the application range of dielectric permittivity biomass measurements to on-line monitoring of physiological changes during bacterial fermentations. In an industrial fermentation of Bacillus thuringiensis, it is important to verify the intactness of bacterial plasmid content in all steps of culture. Changes in certain plasmid resident properties o...
