Abstract:
A needle access assembly and method for obtaining percutaneous needle access with little or no fluoroscopy. The method can include selecting a target for percutaneous access, directing a laser guide at a desired needle-insertion angle and in line with the selected target, aligning the needle access assembly with the laser, and inserting the needle into the target.
Abstract:
In one aspect, engineered hematopoietic stem cells comprising a heterologous expression cassette are provided. In some embodiments, the expression cassette comprises a promoter operably linked to a polynucleotide that encodes a 1α-hydroxylase protein, wherein the 1α-hydroxylase protein is human cytochrome P450 family 27 subfamily B member 1 (CYP27B1).
Abstract:
A thin chitosan-based material can be used for biomedical applications. The chitosan has been treated in a nitrogen field by applying energy to ionize nitrogen in and around the chitosan material. A single or multiple such treatments may be employed. For example, the chitosan material may be irradiated under nitrogen using γ-irradiation, treated under a nitrogen plasma, or both. A thin chitosan material can be readily treated by surface modifying treatments such as irradiating under nitrogen using γ-irradiation, treating under a nitrogen plasma, or both.

Abstract:
Irradiation treatment can be used before, during, or after a surgical treatment or other injury to the brain to decrease or prevent subsequent injury. Injury to the brain during surgery can induce the infiltration of peripheral immune cells, including splenic immune cells, into the brain. The infiltration of immune cells can create acute elevations in brain edema and blood-brain barrier disruption thereby decreasing neurological recover and patient outcomes. Irradiation of peripheral immune cells, or the region of the body in which the cells are derived, can allow for inactivation of the cells and prevent infiltration into the surgical site, for example, the brain.
Abstract:
A substance for treating a cerebral amyloid angiopathy related condition or disease affecting cerebrovasculature in a patient, comprising an inhibitor that causes inhibition of the formation of membrane attack complex of the complement system; and a vehicle for transporting the inhibitor into the cerebrovasculature; where the inhibition by the inhibitor is sufficient to decrease the incidence of or to prevent the incidence of cytolysis of the smooth muscle cells. A method for treating a cerebral amyloid angiopathy related condition or disease affecting cerebrovasculature in a patient, comprising: a) identifying a patient with a cerebral amyloid angiopathy related condition or disease; b) providing one or more than one substance that comprises an inhibitor that causes inhibition of the formation of membrane attack complex of the complement system, c) administering one or more than one dose of the one or more than one substance to the patient.

Abstract:
In one aspect, anabolic agent fusion proteins and compositions comprising anabolic agent fusion proteins are provided. In some embodiments, the anabolic agent fusion protein comprises a platelet derived growth factor (PDGF) or a fibroblast growth factor (FGF) and an Asp-Ser-Ser tripeptide (DSS) repeat sequence. In another aspect, methods of promoting bone growth and methods of treating a fracture using anabolic agent fusion proteins and compositions comprising anabolic agent fusion proteins are provided.
Abstract:
A chitosan material is treated in a nitrogen field by applying energy to ionize nitrogen in and around the chitosan, and the chitosan material is formulated into a hydrogel which can be utilized as a drug delivery vehicle for medicaments or therapeutic agents to treat certain conditions, such as cancers.
