Climbing fiber discharges within the rat cerebellar cortex have been shown to display synchrony, especially for climbing fibers terminating in the same parasagittal bands. In addition, Purkinje cells which have the smallest rostrocaudal separation also seem to have the highest degree of synchrony. But this has so far only been investigated for distances down to 250 mum. In the present study, we wa

This paper overviews traffic engineering problems encountered in the design of multiple networks. We mainly inspect the problem of introducing an n x 64kbit/s service into a non-hierarchial telephone network and focus on network dimensioning.

Granins are major constituents of dense-core secretory granules in neuroendocrine cells, but their function is still a matter of debate. Work in cell lines has suggested that the most abundant and ubiquitously expressed granins, chromogranin A and B (CgA and CgB), are involved in granulogenesis and protein sorting. Here we report the generation and characterization of mice lacking chromogranin B (

In the study of aggrecan fragmentation several methods to extract and purify aggrecan from cartilage and synovial fluid (SF) are used. This work compares and evaluates the effectiveness for purification of aggrecan of the most commonly used methods by the ratio of sulfated glycosaminoglycan (sGAG) to protein and by fragment analysis by Western blot. A novel method for purification of aggrecan frag

The aim of this investigation was to assess the Ku70/Ku80 complex as a potential target for antibody imaging of prostate cancer. We evaluated the in vivo and ex vivo tumor targeting and biodistribution of the (111)In-labeled human internalizing antibody, INCA-X ((111)In-DTPA-INCA-X antibody), in NMRI-nude mice bearing human PC-3, PC-3M-Lu2 or DU145 xenografts. DTPA-conjugated, non-labeled antibody

Age is the most important risk factor known for cardiovascular disease manifestations. However, the biological ageing of an individual may be substantially different from the chronological age in what has been called “differential ageing”. This process can be evaluated by arterial stiffness (pulse wave velocity), and the marker of telomere length and by levels of telomerase enzymatic activity. Sev

Seven mols. isolated from lichen species were tested as antioxidants and photoprotectors of UV-B (280-315 nm.) radiation. Perlatolic acid was the best of these seven mols. The decarboxythamnolic, usnic and usnic acid deriv. showed activity as photoprotectors. Finally, thamnolic acid showed good scavenging activity.
