          Preview
          Description

          The bone marrow play an important role as a hematopoietic organ, and bone diseases such as osteomyelitis and myeloma cause severe morbidity. Since the bone marrow is not an organ to which surgical therapy is an option, the bone marrow diseases are mainly subject to medical treatment, such as by chemotherapy. There is a great need for drug delivery systems that have the ability to effectively deliver therapeutic agents to the bones or bone marrows. The inventors have identified novel drug delivery materials that have the ability to target therapeutic agents to the bones with high specificity. These agents also have the ability to result in accumulation of therapeutic agents in bones or bone marrow. This is based on the fact that the vesicles were intravenously administered to a living body and the distribution of the vesicles in the organs in the body was quantitatively analyzed. The experiments have been conducted using rabbit and monkeys.

          Features and Advantages:
          * Nano-sized lipid vesicles (liposome technology)
          * Surface modification of the vesicles with carboxylic acids (SA) and polyethylene glycol (PEG) chains
          * Bone marrow-directing drug delivery material (Intravenous infusion)
          * Site-specific drug delivery system targeting bone marrow for various drugs
          * High blood compatibility and biodegradability

          Possible Applications:
          Drug delivery material which may be used in various applications such as diagnosis, treatment of prevention of diseases of bone, bone marrow, cartilage, and joint

              Description

              DESCRIPTION
              The importance of the filters toxicity concerns has been greatly exacerbated in recent years to the point that the producers of raw materials and technical formulators have implemented various strategies in order to develop stable and safe sunscreens. In this context, the use of “SPF boosters”, raw materials are able to increase the SPF of a formulation of the sun exploiting different mechanisms of action, is an interesting approach in the development of solar products.
              Considerable interest has also led to the preparation of formulations for the protection from oxidizing agents (ozone, hypochlorite and environmental pollutants) responsible for a pathological condition, such as oxidative stress, which can damage different cell structures. Oxidative stress, indeed, involves a degradation of cells and tissues with a loose in their efficiency. The premature aging of the skin is one of the most popular signs. This idea is based on the use of polyvinylpyrrolidone (PVP) functionalized with antioxidant molecules such as rosmarinic acid, ellagic acid, epigallocatechin gallate, resveratrol, hydroxytyrosol, to be used as boosters of SPF and / or protective agents for skin and hair from exogenous factors such as harmful UV radiation, ozone and chemical oxidants.

              APPLICATION
              At present, polymeric and antioxidant compounds, such as polyphenols, are individually used in cosmetic, pharmaceutical and nutraceutical formulations, but no examples of antioxidant-polymer conjugates are reported.
              ADVANTAGES
              The use of polymeric materials functionalized with antioxidant molecules can combine the advantages of both polymeric materials and antioxidant molecules. In particular:
              Lower degradability of the polymer: the conjugation of a polymeric system with antioxidant molecules confers higher stability to the polymer backbone, which will be less susceptible to degradation reactions.
              Increased stability of the antioxidant molecule: the presence of a covalent bond avoids the effects of migration and extrusion of the antioxidant molecule, which are typical of formulations in which the antioxidant is simply mixed with the other ingredients of the preparation.
              Enhanced security: the conjugation of the polymer with the antioxidant molecule reduces the toxic effects related to the skin absorption which can cause various effects including the accumulation in tissues.
              Speed of preparation: the synthetic strategy is easily modulable.
              Easy industrial scale up: the synthetic strategy allows to operate in non-drastic conditions.
