The present invention discloses compositions and methodologies for the utilization of probiotic organisms in therapeutic compositions. More specifically, the present invention relates to the utilization of one or more species or strains of lactic acid-producing bacteria, preferably strains of Bacillus coagulans, for the control of gastrointestinal tract pathogens, including antibiotic-resistant gastrointestinal tract pathogens, and their associated diseases by both a reduction in the rate of colonization and the severity of the deleterious physiological effects of the colonization of the antibiotic-resistant pathogen. In addition, the present invention relates to the utilization of therapeutic compounds comprised of lactic acid—producing bacteria and anti-microbial agents such as antibiotics, anti-fungal compounds, anti-yeast compounds, or anti-viral compounds. The present invention also discloses methodologies for: (i) the selective breeding and isolation of probiotic, lactic acid-producing bacterial strains which possess resistance or markedly decreased sensitivity to anti-microbial agents (e.g., antibiotics, anti-fungal agents, anti-yeast agents, and anti-viral agents); and (ii) treating or preventing bacteria-mediated infections of the gastrointestinal tract by use of the aforementioned probiotic bacterial strains with or without the concomitant administration of antibiotics. While the primary focus is on the treatment of gastrointestinal tract infections, the therapeutic compositions of the present invention may also be administered to buccal, vaginal, optic, and like physiological locations.

A composition and method for producing interconnective macroporous, resorbable and injectable calcium phosphate-based cements (MICPCs). The composition of the invention sets to poorly crystalline apatitic calcium phosphate after mixing a powder component and an aqueous solution. The multiphasic calcium phosphate components in the cement resorb at different rates allowing the timely replacement by new bone. The interconnected macroporosity in the cement allows for vascularization, entrapment of growth factors, cell colonization and tissue ingrowth. This MICPC can be used for dental and medical applications relating to bone repair, augmentation, reconstruction, regeneration, and osteoporosis treatment, and also for drug delivery, and as scaffolds for tissue engineering.

An aeroponic plant growing system includes a water reservoir and growing chambers for growing plants in an aeroponic environment. A pump, a water distribution manifold, and water lines are used to provide water and nutrients from the water reservoir to sprayers in the growing chambers where the water and nutrients are sprayed on the roots of plants growing therein. The water distribution manifold and water lines preferably are provided as closed loop systems, such that water is provided to all sprayers despite a blockage in the manifold or a water line. Non-absorbed water and nutrients are returned to the water reservoir from the growing chambers on water return lines via a filter that includes multiple types of filter media, including filter media that support the colonization of organisms that support plant growth.

The present invention provides safe paint and coating compositions comprising at least one environmentally acceptable phytochemical such as, but not limited to capsicum, grapefruit seed extract and menthol suitable for use in preventing the colonization of a treated surface by a variety of biological species.
