Neural regeneration peptides and methods for their use in treatment of brain damage

The invention discloses a family of peptides termed NRP compounds or NRPs that can promote neuronal migration, neurite outgrowth, neuronal proliferation, neural differentiation and / or neuronal survival, and provides compositions and methods for the use of NRPs in the treatment of brain injury and neurodegenerative disease. NRP compounds can induce neurons and neuroblasts to proliferate and migrate into areas of damage caused by acute brain injury or chronic neurodegenerative disease, such as exposure to toxins, stroke, trauma, nervous system infections, demyelinating diseases, dementias, and metabolic disorders. NRP compounds may be administered directly to a subject or to a subject's cells by a variety of means including orally, intraperitoneally, intravascularly, and directly into the nervous system of a patient. NRP compounds can be formulated into pharmaceutically acceptable dose forms for therapeutic use. Methods for detecting neural regeneration, neural proliferation, neural differentiation, neurite outgrowth and neural survival can be used to develop other neurally active agents.

Biocompatible wound dressing

A biocompatible wound dressing comprised of a pad for insertion substantially into a wound site and a wound drape for sealing enclosure of the foam pad at the wound site. The pad, comprised of a foam or other like material having relatively few open cells in contact with the areas upon which cell growth is to be encouraged so as to avoid unwanted adhesions, but having sufficiently numerous open cells so that drainage and negative pressure therapy may continue unimpaired, is placed in fluid communication with a vacuum source for promotion of fluid drainage, as known in the art. The pad is further comprised of an ultra-low density fused-fibrous ceramic, or a bioabsorbable branched polymer, or cell growth enhancing matrix or scaffolding.

Systems for Atomic Layer Deposition of Oxides Using Krypton as an Ion Generating Feeding Gas

An atomic layer deposition system and method utilizing radicals generated from a high-density mixed plasma for deposition is disclosed. A high-quality oxide or oxynitride can be deposited by exposing a substrate to a first precursor which is adsorbed onto the substrate during a first phase of one deposition cycle. After purging the deposition chamber, the substrate is exposed to a second precursor which includes oxygen radicals and krypton ions formed from the high-density mixed plasma. The ions and radicals are formed by introducing a radical generating feed gas (e.g., O2) and an ion generating feed gas into a plasma chamber and exciting the gases to form the high-density mixed plasma. The radicals and ions are then introduced to the substrate where they react with the first precursor to deposit a layer of the desired film. Krypton is preferably used as the ion generating feed gas because the metastable states of krypton lead to an efficient dissociation of oxygen into oxygen radicals when compared with other inert gases.

Flash Heating in Atomic Layer Deposition

System and methods for flash heating of materials deposited using atomic layer deposition techniques are disclosed. By flash heating the surface of the deposited material after each or every few deposition cycles, contaminants such as un-reacted precursors and byproducts can be released from the deposited material. A higher quality material is deposited by reducing the incorporation of impurities. A flash heating source is capable of quickly raising the temperature of the surface of a deposited material without substantially raising the temperature of the bulk of the substrate on which the material is being deposited. Because the temperature of the bulk of the substrate is not significantly raised, the bulk acts like a heat sink to aid in cooling the surface after flash heating. In this manner, processing times are not significantly increased in order to allow the surface temperature to reach a suitably low temperature for deposition.
