A closure for dispensing one or more active agents into a container comprises a sealed or sealable chamber having a breakable wall and a hollow piston slidably mounted in a piston guide. Said hollow piston comprises an outer wall having an end in the chamber and at least one ventilation aperture. Said end has a cutting formation. Said hollow piston is slidable in the piston guide between a ventilation position in which the at least one ventilation aperture allows ventilation of the chamber and a sealed position in which the at least one ventilation aperture is sealed to prevent ventilation of the chamber and a deployed position in which the cutting formation has broken through at least a portion of the breakable wall. The outer wall has a retaining formation which engages with the piston guide to releasably resist sliding of the hollow piston between the ventilation position and the sealed position and the deployed position. The hollow piston may have an outer wall, and said outer wall has an end within the chamber, facing the breakable wall, wherein the cutting end has a first edge having a cutting formation and a gap in said cutting formation.

The present invention provides aspartyl-tRNA synthetase derived proteins (DRS polypeptides) with altered cysteine content, compositions comprising the same, and methods of using such polypeptides and compositions for treating or diagnosing a variety of conditions. The DRS polypeptides of the invention have immunomodulatory properties, and exhibit improved activity and stability.

In one aspect, a particle comprising a core containing at least one pharmaceutically active agent and a coating covering the surface of the particle that comprises a biocompatible adhesive polymer is provided. The core may comprise two or more components, such as two pharmaceutically active agents or a pharmaceutically active agent and a major constituent of the core, having at least one dissimilar chemical or physical property (e.g., molecular weight, solubility, c Log P). In some such embodiments, placement of the uncoated core in certain environments results in the rapid release of a component (e.g., a pharmaceutically active agent) from and/or destabilization and breakdown of the core. In some embodiments, the biocompatible adhesive polymer in the coating acts as a molecular glue to stabilize the core and/or alter the release kinetics of at least one pharmaceutically active agent.

The invention relates to truncated growth factors and variants thereof. The invention also relates to methods of making and using the truncated growth factors.

The present invention generally relates to compositions and methods for treatment of subjects having or at risk of arteriosclerosis, hypertension, sickle-cell anemia, or other conditions. In some cases, the composition may include nitric oxide, peptides, or both. The nitric oxide and/or peptide may be present within a first phase comprising a lecithin, such as phosphatidylcholine. In certain embodiments, the lecithin is present in liposomes, micelles, or other vesicles containing nitric oxide and/or peptide. The composition can take the form of a gel, a cream, a lotion, an ointment, a solution, a solid “stick,” etc., that can be rubbed or sprayed onto the skin. Other aspects of the present invention are generally directed to methods of making or using such compositions, methods of promoting such compositions, kits including such compositions, or the like.
