Abstract: Ex vivo and in vivo methods of expanding a population of stem and/or progenitor cells, while at the same time reversibly inhibiting differentiation of the stem and/or progenitor cells by providing the stem and/or progenitor cells with an effective amount of at least one copper chelate, so as to maintain a free copper concentration available to said cells substantially unchanged, to thereby expand the population of said stem and/or progenitor cells, while at the same time reversibly inhibit differentiation of said stem and/or progenitor cells.

Abstract: The present invention describes novel, cost-effective and rapid processes suitable for recycling and degradation of specially designed plastics, which are instantly degradable synthetic polymeric plastics having the characteristics and properties of conventional forms of plastics. These novel plastic products are made from a variety of compositions of polymers and their compatible nontoxic modifiers. The resulting novel instant degradable plastic products retain latent solubility properties which are triggered upon mild chemical processes of the present invention, thus enabling cost effective and facile recycling of plastic refuge.

Abstract: A novel class of instant degradable synthetic polymeric plastics having the characteristics and properties of conventional forms of plastics is developed by providing a new application advantage of incorporating latent, labile, dormant chemical bond nuclei such as disulfide and sulfenyl derivatives of the plastic compounds with latent nucleophilic properties. The special advantage of the instant degradable polymers over the existing biodegradable and other degradable polymer counterparts, is their engineering and design, which makes the kinetics of their degradation instant, and the chemical and physical properties of their by-products allows soluble dissolution into non-toxic aqueous solvent media, thus enabling a practical treatment of waste and avoiding bio-hazardous pollution of the environment. These novel plastic products are made from a variety of compositions of polymers and their compatible nontoxic modifiers.
