    Abstract: This invention is for improving the manufacturing pharmaceutical grade CBD and other cannabinoids following current Good Manufacturing Practices (cGMP) of the US FDA for use in clinical trials for CNS and other indications by the NIH and other researchers. The major cannabinoids in marijuana (Cannabis) and hemp originate from Cannabigerolic Acid (CBGA) present in the biomass of the plant. Plant enzymes that are specific to different strains of biomass converts CBGA to different carboxylic acids of cannabinoids including Cannabidiolic Acid (CBDA) and Δ9-Tetrahydrocannabinolic Acid (Δ9-THCA). These are relatively stable in the growing and fresh-cut plants. These are converted by thermal decarboxylation to Cannabidiol (CBD) and Δ9-Tetrahydrocannabinol (Δ9-THC), carbon dioxide and water. Cannabinoids can be manufactured by first heating the Cannabis biomass to convert carboxylic acids prior to extraction and purification. Alternatively, and preferably because of manufacturing cost and product stability, the carboxylic acids can be first extracted and purified. They can be utilized in the carboxylic acid form or stored in a stable manner until converted to cannabinoids for use in medicine. This invention provides an efficient method for their conversion utilizing a high-pressure reactor under inert conditions.

    Abstract: This invention is for an improved process to co-encapsulate hydrophobic drugs and hydrophilic drugs in phospholipid liposomes. Non-toxic supercritical or near-critical fluids with/without polar cosolvents are utilized to solubilize phospholipid materials and hydrophobic drugs, and form uniform liposomes to encapsulate hydrophobic drugs and hydrophilic drugs.

    Abstract: St. John's Wort products which have enhanced bioactivity in a serotonin re-uptake assay and enhanced stability are identified and manufactured from Hypericum perforatum biomass with supercritical and near critical fluids with and without polar cosolvents. These fluids are used to fractionate the biomass materials in several sequential steps. In each step, the biomass is subjected to a multiplicity of supercritical or near critical fluid extraction steps, with different solvation conditions used for each fraction. Thus, fractionation of the biomass is effected and the St. John's Wort products are manufactured. In addition to excellent overall yield, the bioactivity and stability of the St. John's Wort products manufactured from Hypericum perforatum biomass with supercritical and near critical fluids with and without polar cosolvents are significantly higher than that obtained by conventional organic phase extraction.

    Abstract: The present invention is for a continuous-flow pathogen reduction apparatus and method, based purely on pathogen inactivation physical principles, for controlling or eliminating trans fusion-transmittable infections from emerging pathogens, pandemic viruses, and bioterrorism threats. The invention inactivates both nonenveloped and enveloped viruses as well as pathogenic bacteria and parasites in human plasma and biologies, while retaining the natural bioactivity, integrity and potency of the treated biologic. The method uses critic al, near-critical or supercritical fluids for viral and pathogen reduction of plasma and biologies. The apparatus is designed to rapidly process high volumes of plasma and biologies with high levels of pathogen reduction in a continuous flow fashion.

    Abstract: This invention relates to methods and systems for removing plaque from arteries and blood vessels in human subjects non-invasively utilizing coated superparamagnetic nanoparticles introduced into the human bloodstream and controlled by external magnetic fields to effect plaque removal. Magnetic nanoparticles are injected into a patient, and magnetic fields are used to move the nanoparticles to the site of an arterial blockage. The nanoparticles are then oscillated by means of an alternating current source and oscillating magnetic field. The nanoparticles impact the plaque deposit, causing it to break up, so that it may be safely disintegrated, dissolved in the bloodstream, digested by enzymes or ions and/or removed with the nanoparticles themselves. The nanoparticles are removed by a unipolar magnetic field directing them to be removed at the point of injection or alternative location in the body. The nanoparticles are also removed by natural bodily functions. The methods and systems are directed to the emergency clearance of arteries in the human body, and the routine annual and quarterly clearance and preventative maintenance of arteries in the human body.
