Patent number: 8658193Abstract: Technologies are described herein for styptic compounds comprising a hemostatic or styptic agent suspended within a hydrophobic carrier medium. Example carrier mediums may include waxes, lipids, oils, or combinations thereof. The compound may be a semisolid at room temperature and soft enough to be easily dispensed and formed into or onto bleeding tissue of an animal or human. The hydrophobic qualities of the carrier medium can protect the styptic agent from absorbing moisture. The carrier medium can mechanically support positioning treatments adjacent to the bleeding tissue. The carrier medium can further serve to mechanically seal the tissue to aid in hemostasis while also protecting the tissue from debris and contamination. The carrier medium can aid in maintaining moisture within the tissue. Slurry-based manufacturing processes can support a substantially homogeneous dispersal of styptic agent throughout the carrier medium.Type: GrantFiled: June 8, 2012Date of Patent: February 25, 2014Inventor: Robert J. Greenwald

Patent number: 8357719Abstract: A drug having a muscle relaxing effect can be prepared by binding negatively charged gold nanoparticles having a size of 1.4 nm fitted to synaptic clefts to choline through ionic bonds, thereby inducing gold-sulfur bonds in the Cys loop of an acetylcholine receptor in neuromuscular junction, and thus blocking the electric current induced in signal transduction from a nerve to a muscle, thereby blocking neuromuscular transmission chemically and physically. When the reverse is administered after surgery, the gold-sulfur bonds are broken due to the re-flow of the electric current, and thus the gold nanoparticles are again released and metabolized into neuromuscular junction. Further, such muscle relaxing effect can be applied as an anticonvulsant.Type: GrantFiled: November 22, 2007Date of Patent: January 22, 2013Inventor: Chur Chin

Patent number: 6939566Abstract: Microbicidal formulations are described which are preferably ecologically friendly and non-toxic to mammals, and are highly effective against a broad spectrum of detrimental pathogenic microorganisms. The microbicidal formulation contains complexes having the formula R-M, wherein R is at least one organic chelating moiety and M is at least one metal ion which is microbicidal to at least one microorganism. These complexes can disrupt microorganism activities by penetrating the natural protecting bio-films of such microorganisms through the reaction of the R-group with the organic constituents of these microorganisms while releasing M into their intra-cellular media. Thus, this process exhibits its biocidal activities from the inside-out, contrary to other methods which rely on damaging the protective biofilms.Type: GrantFiled: January 17, 2001Date of Patent: September 6, 2005Inventors: Kareem I.

Patent number: 6630172Abstract: Disinfectant formulations are described which are preferably ecologically friendly and non-toxic to mammals and plants, and are highly effective against a broad spectrum of detrimental pathogenic microorganisms. The microbicidal formulation contains complexes having at least one metal ion which is microbicidal to at least one microorganism and potassium sodium tartrate in some form. When potassium sodium tartrate is used with these metal ions, it enhances the complex-forming properties of such metal complexes while concurrently increases their efficacy and potency at the same level of metal ion concentrations. These microbicidal formulations can be diluted in suitable proportions into aqueous systems to produce the desired dosages for each individual case, depending on the level and the severity of the contamination. The microbicidal formulations can be applied by conventional methods, e.g., spraying, soaking, fogging, impregnation, and the like.Type: GrantFiled: January 22, 2001Date of Patent: October 7, 2003Inventor: Kareem I.

Patent number: 6391879Abstract: A therapeutic solution and application procedure for curing and preventing nail fungus and athlete's foot infections or Onychomycosis comprising a combination of an anti-fungal agent with DMSO in a anhydrous solution of Polyglycol. The DMSO acts as a solvent so that active anti-fungal agents such as Tolnaftate can be delivered directly to fungal infected areas under and around the nail and other areas prone to topical tinea infections. The DMSO, and Tolnaftate dissolved in a viscous solution of polyglycol so that the combined ingredients may be applied directly to the affected areas with superior penetration. The therapeutic solution is formulated by dissolving the Tolnaftate into the DMSO, and then combining the DMSO and polyglycol solutions together to form the therapeutic solution. Repeated applications of the resulting solution on Onychomycosis infected nails over one 4-6 week period yields satisfactory result rates as high as 85-90% without augmenting the therapy with systemic drugs.Type: GrantFiled: August 17, 2000Date of Patent: May 21, 2002Assignee: Astan, Inc.Inventor: Stanley Forrest Reeves

Patent number: 6207699Abstract: Numerous studies have documented that medications which increase brain serotonin (5-HT) are effective anorectic agents which help obese patients lose weight and which also decrease craving for sweets and carbohydrates. Evidence from other studies also indicate that increases in brain 5-HT may help decrease craving for alcohol and cocaine. 5-hydroxy-L-tryptophan, abbreviated 5-HTP, is the immediate precursor of serotonin (5-HT). When administered in combination with an inhibitor of peripheral decarboxylase such as carbidopa, 5-HTP increases brain serotonin. Increases in synaptic 5-HT decreases the firing rate of 5-HT neurons via stimulation of inhibitory 5-HT1a receptors located on the cell bodies in the raphe. This serves as a negative feedback loop. The clinically available beta adreneric receptor antagonist medication pindolol is also a 5-HT1a antagonist, and can be used to increase the ability of 5-HTP to increase brain 5-HT. Previous studies with 5-HTP used doses exceeding 50 mg per day.Type: GrantFiled: June 18, 1999Date of Patent: March 27, 2001Inventor: Richard Brian Rothman
