Abstract. Proton-transfer-reaction time-of-flight mass spectrometry (PTR-ToF-MS) is a technique commonly used to measure ambient volatile organic compounds (VOCs) in urban, rural, and remote environments. PTR-ToF-MS known produce artifacts from ion fragmentation, which complicates the interpretation quantification of key atmospheric VOCs. This study evaluates extent fragmentation other ionization processes impact urban measurements ions typically assigned isoprene (m/z 69, C5H8H+),...

The ability of normal and cataractous human lenses to accumulate amino acids synthesize proteins was studied under organ culture conditions. As expected, regulate their internal ion levels, against a concentration gradient, continue even in advanced age (> 60 yrs).The fell basically into two groups. Those with low sodium calcium content behaved similar manner lenses, but high contents showed markedly reduced acid synthesized less molecular weight protein. They incorporated, however, much...
AbstractThe 115kDa cytoskeletal beaded filament protein of bovine lens fibres is degraded during opacification induced by increased internal calcium. The monoclonal antibody R2D2 to this has been used in whole lenses and native homogenates follow the process degradation production break-down products. In opaque outer cortex with an Ca2+ 2.0mM, both parent main product (57kDa) were reduced amount almost 60%. No additional products detected antibody. When incubated overnight 10mM could no...
Ionic homeostasis is essential to lens clarity and the epithelium plays a large part in homeostasis, through vectorial transport. In most epithelia maintenance of function depends on cytoskeleton. Capsule/epithelium preparations from human donor lenses have been used for immunohisto-chemical investigations both normal epithelial cell cytoskeletal structure, structural changes induced by increasing calcium. A sustained increase intracellular calcium, incubation with A23187 W7, led loss...
