The dynamics of axonal arbors during synaptogenesis and their plasticity in the adult nervous system remain poorly understood. Axonal filopodia, which emerge from the shaft of axonal branches and contain small synaptic vesicle clusters, initiate synaptic formation. We found that the movement of axonal filopodia is strongly inhibited by the neurotransmitter(More)
Disruption of the presynaptically enriched polyphosphoinositide phosphatase synaptojanin 1 leads to an increase of clathrin-coated intermediates and of polymerized actin at endocytic zones of nerve terminals. These changes correlate with elevated levels of PI(4,5)P(2) in neurons. We report that phosphatidylinositol phosphate kinase type Igamma (PIPKIgamma),(More)
The vapor phase deposition of polymeric antimicrobial coatings is reported. Initiated chemical vapor deposition (iCVD), a solventless low-temperature process, is used to form thin films of polymers on fragile substrates. For this work, finished nylon fabric is coated by iCVD with no affect on the color or feel of the fabric. Infrared characterization(More)
Introduction. The order of magnitude of the characteristic values pn [K] of the kernel K(x, y) of a linear integral equation has been discussed by many writers, including Fredholm [4]0), Mercer [ll], Schur [12], Weyl [17, 18], Lalesco [9], Mazurkiewicz [lO], Carleman [l, 2], Gheorghiu [5], and Hille and Tamarkin [8]. The order of magnitude of the singular(More)
