Provided are injectable, hyaluronic acid-based hydrogel compositions including conjugated vitamins.

The present invention relates to the contacting of one or more surfaces of an implantable medical device with one or more diketopiperazines (DKPs).

In one aspect, the present disclosure pertains to elutable coating compositions that comprise an excipient comprising a bio-degradable or bio-stable polymer selected from a poly(lactic-co-glycolic acid) (PLGA) or methyl cellulose (MCC), a binding agent; a therapeutic agent. In some embodiments, the elutable coating compositions further comprise a solvent, in which case such compositions may be, for example, applied to a substrate in the form of a layer and subsequently dried, thereby forming an elutable coating on the substrate.

Generally, the invention is in relation to the field of drug delivery devices to augment standard radiation therapy and methods of making and using same. Specifically, this technology utilizes a controlled release of drug from a coated balloon for local intratumoral drug delivery to breast tissue to supplement or replace standard radiation therapy.

The present disclosure relates to compounds, which are useful for regulating the expression of apolipoprotein A-I (ApoA-I), and their use for treatment and prevention of cardiovascular disease and related disease states, including cholesterol- or lipid-related disorders, such as, for example, atherosclerosis.

Disclosed herein are compositions and methods of making and using such compositions. Polyhydric polymers may be converted to derivatives thereof by reaction with divinyl sulfone to provide vinyl sulfone substituted polymers, where the polymers may additionally be crosslinked, and the crosslinked and non-crosslinked derivatives may be used in biomedical and other applications.

A device for protecting neurons and reducing inflammation and adhesion formation following surgery is provided. Also provided is a method for protecting neurons and reducing inflammation and adhesion formation following surgery. The device includes a bioabsorbable substrate and a layer of an oxidation inhibitor mimicking the effects of superoxide dismutase and catalase enzymes located on a surface of the substrate. Oxidation inhibitors that may be used include EUK-8, EUK-134, EUK-189, and EUK-207 (a mimetic of superoxide dismutase/catalase), monosodium luminol or phenyl N-t-butylnitrone or an analog with similar anti-oxidant properties. The oxidation inhibitors reduce oxidative stress and trigger the subject's natural anti-oxidant and anti-inflammatory defenses, thereby reducing neuron death, loss of neuron connectivity, inflammation and scarring and restoring excitatory function of neurons.

A conical shaped venous valve structure formed from collagenous mammalian tissue. The valve structure includes a plurality of fluid flow modulating means that open and allow antegrade blood to be transmitted out of the valve structure and, into and through an associated cardiovascular vessel, when the valve structure is disposed in the cardiovascular vessel and the antegrade blood exhibits a positive pressure relative to the exterior pressure, whereby a negative hydrostatic pressure gradient is generated or present proximate the flow modulating means and/or a first positive pressure differential between first internal valvular pressure and first external valvular pressure is generated proximate the flow modulating regions, and close and prevent retrograde blood from flowing into the valve structure and, thereby, cardiovascular vessel, when a positive hydrostatic pressure gradient is generated or present proximate the flow modulating means and/or the first positive pressure differential transitions to a second pressure differential between second internal valvular pressure and second external valvular pressure, the second pressure differential being lower than the first positive pressure differential.

Disclosed is absorbable bone wax and a preparation method thereof. The preparation method comprises the steps of: 1) mixing polyoxypropylene polyoxyethylene block copolymer (PEG-PPG-PEG) and polyoxypropylene polyoxyethylene random copolymer (PEG-PPG), and stirring evenly under heating to obtain a liquid mixture; 2) under mechanical stirring and heating condition, adding hemostatic starch microspheres to the liquid mixture obtained in step 1) to obtain a uniformly-mixed liquid; and 3) adding a bone repair material to the uniformly-mixed liquid obtained in step 2), and mixing uniformly to obtain a mixed solution, then pouring the mixed solution into a mold or sub-packaged bottle, and leaving at room temperature for solidifying and shaping to give the absorbable bone wax. The absorbable bone wax of the present invention can achieve the effect of rapid hemostasis, changing the relatively single hemostasis method with traditional bone wax which only depends on physical sealing.
