The Development and Validation of a Comprehensive List of Primary Sources in College Reading Instruction
It may be argued that a field only comes of age when its professional membership is able to gain insight into the present and begin to predict the future through the organized studying and the collective valuing of the field\u27s past. As we enter the 1990\u27s, it is time for the field of college reading and learning assistance to achieve a broader perspective that more fully incorporates the field\u27s rich and varied past. To achieve this end, collectively we should endeavor to understand our professional roots through chronicling, interpreting, and evaluating the fundamental ideas, the pedagogical achievements, and the research contributions of our colleagues, both past and present

Biomedical Technologies for In Vitro Screening and Controlled Delivery of Neuroactive Compounds
Hydrogel-coated microelectrode array for neural interface
Recently, hydrogel has been extensively used in various biomedical applications including soft contact
lenses, wound healing materials and as a means for controlled drug delivery and release. In this
study, we propose to use hydrogel as a novel neural interface. Planar microelectrode arrays were
coated with hydrogel in order to improve the quality of the interface and to aid in drug delivery to cells
on microelectrode arrays (MEAs).This work was supported by the International

Synaptic Connectivity of a Low Density Patterned Neuronal Network Produced on the Poly-L-Lysine Stamped Microelectrode Array
Rectangular networks of rat hippocampal neurons have been produced on microelectrode arrays (MEAs). The crossing points of networks were located at the recording electrode sites by aligned microcontact printing (muCP) technique. Polydimethysiloxane (PDMS) stamp was fabricated to print fine poly-L-lysine (PLL) patterns of 2 mum-width lines for neurites and 20 mum-diameter circles for cell bodies. Different densities of neurons were applied on the PLL-stamped MEAs to find how a low density of neurons still has the functional connectivity. From the neural network applied with a density of 200 cells/mm2 , we could observe signal propagation among spontaneous activities. Electrical responses were also evoked by 200 muA current pulse stimulation with 50 mus pulse width. Immunocytostaining was employed to identify dendrites, synapses, and nuclei in the patterned neurons.This work was supported by the International Collaboration

Modulation of cultured neural networks using neurotrophin release from hydrogel-coated microelectrode arrays
Modulation of Cultured Neural Networks Using Neurotrophin Release
Polyacrylamide and poly(ethylene glycol) diacrylate hydrogels were synthesized and
characterized for use as drug release and substrates for neuron cell culture. Protein release
kinetics was determined by incorporating bovine serum albumin (BSA) into hydrogels during
polymerization. To determine if hydrogel incorporation and release affect bioactivity, alkaline
phosphatase was incorporated into hydrogels and a released enzyme activity determined using
the fluorescence-based ELF-97 assay. Hydrogels were then used to deliver a brain-derived
neurotrophic factor (BDNF) from hydrogels polymerized over planar microelectrode arrays
(MEAs). Primary hippocampal neurons were cultured on both control and
neurotrophin-containing hydrogel-coated MEAs. The effect of released BDNF on neurite
length and process arborization was investigated using automated image analysis. An
increased spontaneous activity as a response to the released BDNF was recorded from the
neurons cultured on the top of hydrogel layers. These results demonstrate that proteins of
biological interest can be incorporated into hydrogels to modulate development and function of
cultured neural networks. These results also set the stage for development of hydrogel-coated
neural prosthetic devices for local delivery of various biologically active molecules.This work was supported by the International Collaboration
