Abstract

The projection of perturbed orbitals onto the virtual orbital space allows partition of induced current density into contributions from individual virtual excitations between occupied and unoccupied orbitals, enabling the assignment of the origin of currents within the ipsocentric method for calculation of molecular magnetic response. The delocalized currents in benzene and planar cyclooctatetraene are described by transitions within the valence space and localized currents in the benzene [pi] system involve excitations outside the valence space.

Abstract

Rotational spectra of 14 different isotopomers of the hydrogen-bonded dimer H20(super ...)HCl have been calculated. In conclusion, the remaining difference, ascribed to motional averaging, implied an operationally defined angle of oscillation for the HCl moiety of 10--12 degrees.

Abstract

Alzheimer's disease (AD) is characterized by the cerebral deposition of [Beta]-amyloid (A[Beta]). A[Beta] plaques also occur in the brains of healthy aged individuals, and A[Beta] concentrations are increased in the cerebrospinal fluid (CSF) in old age. Based on results from an in vitro senescence model on human fibroblasts, it was proposed that the production of the [Beta]-amyloid precursor protein (APP) was increased during aging. No information was available as to whether APP production was also augmented in aged humans. It was therefore the aim of the present study to analyze APP in connective tissue, skeletal muscle, peripheral blood mononuclear cells, and serum samples from young and aged healthy individuals. APP production was assessed by Northern and Western blotting. The expression of the different APP isoforms was studied by reverse transcription-polymerase chain reaction (RT-PCR) technique. The results demonstrate that APP messenger ribonucleic acid (mRNA) and protein concentrations were identical in blood and tissue samples from young and aged individuals and that there were no age-dependent changes in the APP isoform production pattern. Thus, our data strongly argue against the possibility of an altered production of APP during healthy aging and underline the point that in vitro aging models may not accurately reflect the in vivo situation.
