摘要:
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).
摘要:
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.
摘要:
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.
摘要:
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.

摘要:
The present disclosure relates to an anatomically aligned prosthetic ankle with a passive assist and associated methods. The prosthetic ankle includes a talus movably coupled to a tibia section by a connector about which the talus is pivotal such so during locomotion by a user of the prosthetic ankle. The passive to assist provides a selected dorsi-flexion force to aid in the push-off or pre-swing phases of gait for the user.
摘要:
Provided here are methods of treating Niemann-Pick disease type C (NPC) in a subject or delaying the onset of NPC in a subject by administering to the subject an immunomodulator, or a modulator of amyloid precursor protein (APP) function, or a combination thereof.
摘要:
In one aspect, methods of reversing or delaying the progression of Alzheimer's disease in a subject having Alzheimer's disease or delaying the onset of Alzheimer's disease in a subject having mild cognitive impairment are provided. In some embodiments, the method comprises administering to the subject an oxysterol inhibitor.
