    Dependence of EPSP efficacy on synapse location in neocortical pyramidal neurons (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-03-09
    Description: Neurons receive thousands of synaptic inputs throughout elaborate dendritic trees. Here we determine the somatic impact of excitatory postsynaptic potentials (EPSPs) generated at known dendritic sites in neocortical pyramidal neurons. As inputs became more distal, somatic EPSP amplitude decreased, whereas use-dependent depression increased. Despite marked attenuation (〉40-fold), when coactivated within a narrow time window (approximately 10 milliseconds), distal EPSPs could directly influence action potential output following dendritic spike generation. These findings reveal that distal EPSPs are ineffective sources of background somatic excitation, but through coincidence detection have a powerful transient signaling role.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, Stephen R -- Stuart, Greg J -- New York, N.Y. -- Science. 2002 Mar 8;295(5561):1907-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neuroscience, John Curtin School of Medical Research, Australian National University, Canberra, ACT 0200, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11884759" target="_blank"〉PubMed〈/a〉

    Ti-catalyzed Si nanowires by chemical vapor deposition: Microscopy and growth mechanisms (2001)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Si nanowires grow rapidly by chemical vapor deposition on Ti-containing islands on Si surfaces when an abundant supply of Si-containing gaseous precursor is available. The density of wires is approximately the same as the density of the nucleating islands on the Si surface, although at least two different types of islands appear to correlate with very different wire growth rates. For the deposition conditions used, a minority of long, defect-free wires form, along with more numerous wires containing defects. Energy-dispersive x-ray spectroscopy shows that the Ti-containing nanoparticles remain at the tip of the growing wires. The estimated diffusion coefficient of Si in TiSi2 is consistent with the catalyzing nanoparticle remaining in the solid phase during nanowire growth. © 2001 American Institute of Physics.

    Nanowires of four epitaxial hexagonal silicides grown on Si(001) (2002)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: Epitaxial self-assembled silicide nanowires can be grown on Si (001) if the magnitude of the lattice mismatch between epilayer and substrate is large along one crystal axis and small along the perpendicular axis. This phenomenon is illustrated with four examples: ScSi2, ErSi2, DySi2, and GdSi2, which have lattice mismatches of −4.6%, 6.3%, 7.6%, and 8.9%, respectively, along one of the Si 〈110〉 directions and mismatches of 0.8%, −1.6%, −0.1%, and 0.8%, respectively, along the perpendicular Si〈110〉 direction. The resulting self-assembled nanowires have widths and heights in the range of 3–11 and 0.2–3 nm, depending on the lattice mismatches. The average lengths of the nanowires are in the range 150–450 nm, and are determined primarily by kinetic issues. The epitaxial growth of silicide nanowires should prove interesting to those studying quasi-one- dimensional systems. © 2002 American Institute of Physics.

    Optical characterization of GaAs pyramid microstructures formed by molecular beam epitaxial regrowth on pre-patterned substrates (2001)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: Arrays of GaAs pyramids with square (001) bases of length 1–5 μm have been fabricated by molecular beam epitaxy regrowth on pre-patterned GaAs (001) substrates. The optical properties of the pyramid faces have been studied by microreflection and microtransmission imaging measurements with light (λ=900–1000 nm) incident through the pyramid base. Digitized charge coupled device images indicate that total internal reflection occurs at the {110} pyramid facets and that their reflectivities are greater than 80%, provided overgrowth of the facets does not occur. These properties suggest that such structures may be suitable as the top mirror in novel micron-scale vertical microcavity devices. © 2001 American Institute of Physics.

    The role of α1D-adrenoceptors in prostatic contraction examined using protection studies (2002)

    Notes: 1 The aim of the study was to investigate the role of the α1D-adrenoceptor in α1-adrenoceptor-induced contraction of human prostate by means of protection experiments. 2 Responses of human prostate strips to noradrenaline were recorded, along with responses of rat aorta and vas deferens, tissues possessing predominantly α1D- and α1A-adrenoceptors respectively, for comparison. α1-adrenoceptors were then inactivated by incubation with the irreversible antagonist phenoxybenzamine. In some tissues α1A- or α1D-adrenoceptors were ‘protected’ from inactivation by incubation in the presence of the selective α1A- or 1D-adrenoceptor antagonists 5-methylurapidil and BMY 7378 before recording further responses to noradrenaline. 3 Phenoxybenzamine reduced the maximum noradrenaline-induced response and the potency of noradrenaline in all tissues. In rat vas deferens and human prostate, 5-methylurapidil protected α1A-adrenoceptors in a concentration–dependent manner. In rat aorta, 10 nm BMY 7378 almost fully protected α1D-adrenoceptors. However, concentrations of BMY 7378 up to 30-fold higher failed to protect receptors in the human prostate. 4 These results suggest that in human prostate functional α1D-adrenoceptors do not contribute to noradrenaline-induced contractile responses.

    Muscarinic receptors of the urinary bladder: detrusor, urothelial and prejunctional (2002)

    Notes: 1 The parasympathetic nervous system is responsible for maintaining normal bladder function, contracting the bladder smooth muscle (detrusor) and relaxing the bladder outlet during micturition. 2 Contraction of the bladder involves direct contraction via M3 receptors and an indirect ‘re-contraction’ via M2-receptors whereby a reduction in adenylate cyclase activity reverses the relaxation induced by β-adrenoceptor stimulation. 3 Muscarinic receptors are also located on the epithelial lining of the bladder (urothelium) where they induce the release of a diffusible factor responsible for inhibiting contraction of the underlying detrusor smooth muscle. The factor remains unidentified but is not nitric oxide, a cyclooxygenase product or adenosine triphosphate. 4 Finally, muscarinic receptors are also located prejunctionally in the bladder on cholinergic and adrenergic nerve terminals, where M1-receptors facilitate transmitter release and M2 or M4-receptors inhibit transmitter release. 5 In pathological states, changes may occur in these receptor systems resulting in bladder dysfunction. Muscarinic receptor antagonists are the main therapeutic agents available for treatment of the overactive bladder, but whether their therapeutic effect involves actions at all three locations (detrusor, prejunctional, urothelial) has yet to be established.
