The present disclosure relates to a bone graft composition containing hydroxypropyl methylcellulose and a preparation method therefor. More specifically, a bone graft composition containing hydroxypropyl methylcellulose in an amount that provides optimum osmotic properties and shape retainability, and a preparation method therefor.

Gamma ray and e-beam irradiation provided efficient sterilization of certain self-assembling peptides (including RADA16 in solution) without substantial degradation of the major peptide, while, e.g., another self-assembly peptide, QLEL12 was significantly degraded following irradiation. Irradiation sterilization enhances the rheological property of, for example, RADA16 hydrogel once applied to tissue at a physiological pH. The rheological property increase can result in higher efficacy in a variety of biomedical applications.

A method for sterilising a platelet lysate in the liquid state comprising at least the endogenous growth factors TGF-beta 1, EGF, PDGF-AB, IGF-1, VEGF and bFGF. The method comprising freezing the liquid platelet lysate in order to obtain a frozen platelet lysate, and irradiating the frozen platelet lysate with ionising radiation in order to obtain a sterilised platelet lysate, the irradiation being adapted so as to preserve at least 80% of the concentration of at least one of the endogenous growth factors chosen from the group consisting of TGF-beta 1, EGF, PDGF-AB, IGF-1 and VEGF.

The present disclosure is directed to a method of making a composition by combining a vehicle, e.g., a single phase vehicle, and an insoluble component comprising a beneficial agent, and sterilizing the composition using ionizing radiation prior to use, wherein the beneficial agent is stable following exposure to a sterilizing dose of ionizing radiation. Related compositions and methods are provided.

The invention refers to a process for preparing sterile active pharmaceutical ingredients (APIs) useful in the preparation of sterile product for ophthalmic use. The process comprises the gamma-ray sterilization treatment of the APIs powder in a protective atmosphere.

A biocompatible material for bone repair is described. The bone repair composition includes a mixture of a type I collagen, a type I collagen-glycosaminoglycan coprecipitate, tricalcium phosphate; and bioactive glass. Methods of using the composition for bone repair, and a kit for the bone repair composition are also described.

A ready-to-use, gamma-ray sterilized, surgical antiseptic composition comprising an initial non-toxic concentration of povidone-iodine above a minimum effective concentration of available iodine, iodide in sufficient quantity to provide donor iodine upon gamma irradiation to stabilize said povidone-iodine and maintain said minimum effective concentration of available iodine, and a buffered saline solution.

The invention refers to a process for preparing sterile active pharmaceutical ingredients (APIs) useful in the preparation of sterile product for ophthalmic use. The process comprises the gamma-ray sterilization treatment of the APIs powder in a protective atmosphere.
