The invention provides antimicrobial compositions comprising charged cellulose nanofibrils dispersed in an aqueous solution having a dissolved oxygen content of at least 20 mg/L, preferably from 20 to 100 mg/L. The cellulose nanofibrils may have an increased surface charge due to their carboxylic acid content which contributes to their antimicrobial properties. In particular, the carboxylic acid content may be at least about 1000 μmol/g cellulose, preferably at least about 1400 μmol/g cellulose. The compositions are suitable for use in the treatment of wounds, in particular chronic wounds.

The invention provides a “host-guest” supramolecular hydrogel. The hydrogel contains an AAm/NVP interpenetrating polymer network (IPN) with supramolecular cross-linkers assembled from β-lactam/adamantane-containing guest molecule with host polymeric cyclodextrin (PCD). An advantage of this hydrogel is that because of the molecular association of polymeric cyclodextrin and adamantane, the supramolecular hydrogels self-heal without any external stimuli after the hydrogels are severed. The invention also provides methods of making the hydrogel, methods of making the synthesis intermediates, and methods of diagnosis or treatment of β-lactamase-containing bacteria.

A medicinal chewing gum has an inner core containing a first gum base and a first cannabinoid in a lipophilic nanosized form and an outer layer containing a second gum base and a second cannabinoid in a hydrophilic nanosized form, thereby providing quick release of the second cannabinoid in the outer layer and sustained release of the first cannabinoid in the inner layer. At least one of the inner core and the outer layer contains a synergistic compound having a synergistic effect with at least one of the first and second cannabinoids in the treatment of a medical condition.

Treatments for cancer include miriplatin assembled into an ultra-small dot (uPtD) and/or lomitapide or a pharmaceutically-acceptable salt thereof. The uPtD and/or lomitapide can be encapsulated in a nanoparticle for administration to a subject. Some embodiments further include paclitaxel or a pharmaceutically-acceptable salt thereof.

Disclosed are biocompatible cryogels comprising one or more biomolecules, such as antibodies, protein complexes, enzymes, dna and polysaccharides. Also disclosed are methods of making the cryogels.

The present invention provides preparations of MSCs with important therapeutic potential. The MSC cells are non-primary cells with an antigen profile comprising less than about 1.25% CD45+ cells (or less than about 0.75% CD45+), at least about 95% CD105+ cells, and at least about 95% CD166+ cells. Optionally, MSCs of the present preparations are isogenic and can be expanded ex vivo and cryopreserved and thawed, yet maintain a stable and uniform phenotype. Methods are taught here of expanding these MSCs to produce a clinical scale therapeutic preparations and medical uses thereof.

Described herein are ultra-deformable liposomes comprising a first lipid and second lipid. The first lipid comprises a first hydrophilic head linked to a first aliphatic tail, and the second lipid comprises a second hydrophilic head linked to a second aliphatic tail having at least two carbons less than the first aliphatic tail. The ultra-deformable liposomes described herein are useful, for example, as drug delivery vehicles. Accordingly, also described herein are compositions comprising an ultra-deformable liposome and a cargo, such as a drug, as well as methods for delivering a drug, such as an anti-cancer therapeutic, to a tumor.

The present invention provides an advanced absorption and delivery system to an ecdysterone-based nutritional supplement, specifically a turkesterone-based nutritional supplement, a turkesterone hydroxypropyl β-cyclic dextrin complex manufactured using a co-precipitation technique, the manufacturing process including a fluid bed drying system wherein the complex is dried using hot air blown into contact with a fluidized bed.

Disclosed herein are compositions comprising an NSAID such as meloxicam and/or rizatriptan in combination with a cyclodextrin and/or a carbonate or a bicarbonate. These compositions may be orally administered, for example, to improve the bioavailability or pharmacokinetics of the NSAID for the treatment of pain such as migraine, arthritis, and other conditions. Also disclosed herein are methods of treating pain, such as migraine, comprising administering meloxicam and rizatriptan to a human being suffering from pain, such as migraine. For migraine, these methods may be particularly useful when the meloxicam and rizatriptan are administered while the human being is suffering from an acute attack of migraine pain or migraine aura. In some embodiments, the combination of meloxicam and rizatriptan may be administered in a manner that results in a T.sub.max of meloxicam of 3 hours or less.

A zinc oxide nanocomposition is modified with a homobifunctional imidoester compound and an antibiotic composition contains the zinc oxide nanocomposition as an active ingredient. Also, a combination preparation contains the zinc oxide nanocomposite and an antifungal agent. The zinc oxide nanocomposite provides an antibiotic composition which is less toxic while exhibiting excellent antibiotic activity, for example, antiviral, antibacterial or antifungal activity. The antibiotic composition is usable to prevent contamination or infection by viruses, bacteria or fungi, inhibit the growth of viruses, bacteria or fungi, or treat infections by viruses, bacteria or fungi.
