Cholesterol/sphingolipid microdomains (lipid rafts) in the membrane are involved in protein trafficking, formation of signaling complexes, and regulation of actin cytoskeleton. Here, we show that lipid rafts exist abundantly in dendrites of cultured hippocampal neurons, in which they are associated with several postsynaptic proteins including surface AMPA(More)
The design and implementation of a three-dimensional (3D) location system to provide accurate location information is proposed in this paper. The location information is computed by two techniques. Both Trilateration technique and the Time Difference of Arrival (TDOA) are applied to three sets of collected distance measurements and to obtain accurate(More)
A new continuous cell line, NTU-SE, was established from the pupal tissues of an economically important pest, the beet armyworm Spodoptera exigua (Lepidoptera: Noctuidae). This cell line contains four major morphologic types: round, polymorphic, spindle-shaped, and comma-shaped cells. The population doubling time of this new line in TNM-FH medium(More)
Olfactory transduction in vertebrate olfactory receptor neurons (ORNs) involves primarily a cAMP-signaling cascade that leads to the opening of cyclic-nucleotide-gated (CNG), nonselective cation channels. The consequent Ca2+ influx triggers adaptation but also signal amplification, the latter by opening a Ca2+-activated Cl channel (ANO2) to elicit,(More)
This paper presents the design and implementation of a three-dimensional (3D) location system to provide accurate location information. The location information is computed by applying Trilateration technique on three sets of collected distance measurements. Trilateration technique is implemented to improve the accuracy of the location system. The 3D system(More)
