Abstract: Long-term dialysis requires provision of safe and reliable vascular access, often in the form of an arteriovenous (AV) fistula. The primary cause of AV fistula loss or failure is stenosis caused by intimal hyperplasia (IH) in the graft at the venous anastomosis or the distal vein. Disclosed are methods of using photodynamic therapy (PDT) to inhibit IH in blood vessels which may also be used to inhibit IH and SMC growth at the anastomosis of an AV fistula in vivo.

Abstract: A method of producing Hydrogen by reacting a metal selected from the group consisting of Aluminum (Al), Magnesium (Mg), Silicon (Si) and Zinc (Zn) with water in the presence of an effective amount of a catalyst at a pH of between 4 and 10 to produce Hydrogen. The catalyst or other additive is selected to prevent or slow down deposition of the reaction products on the (impair reactions with the) metal that tend to passivate the metal and thereby facilitates the production of said Hydrogen.
Abstract: An optical switch for controllably switching an interface between a reflective state in which incident light undergoes total internal reflection and a non-reflective state in which total internal reflection is prevented. In one such switch a cell contains a fluid. One side of the cell forms the light incident interface. A membrane is suspended in the fluid. One pair of electrodes is applied to opposite sides of the membrane. Another electrode pair is applied to the cell's interface side and to the cell's opposite side. A variable voltage potential is applied between selected ones of the electrodes. Application of the voltage potential between selected ones of the membrane and cell electrodes moves the membrane into optical contact with the interface, producing the non-reflective state. Application of the voltage potential between other selected ones of the membrane and cell electrodes moves the membrane away from optical contact with the interface, producing the reflective state.

Abstract: Stable clones of neural stem cells (NSCs) have been isolated from the human fetal telencephalon. In vitro, these self-renewing clones (affirmed by retroviral insertion site) can spontaneously give rise to all 3 fundamental neural cell types (neurons, oligodendrocytes, astrocytes). Following transplantation into germinal zones of the developing newborn mouse brain, they, like their rodent counterparts, can participate in aspects of normal development, including migration along well-established migratory pathways to disseminated CNS regions, differentiation into multiple developmentally- and regionally-appropriate cell types in response to microenvironmental cues, and non-disruptive, non-tumorigenic interspersion with host progenitors and their progeny. Readily genetically engineered prior to transplantation, human NSCs are capable of expressing foreign transgenes in vivo in these disseminated locations.
