摘要:
A valve prosthesis (43), such as an artificial venous valve, having a support frame (11) and leaf structure comprising one or more leaflets (78, 79) in which the outer edge (112) of each leaflet engages the inner circumference of the bodily passageway along a serpentine path urged against the passageway by an expandable frame, while the inner edges move in response to fluid to restrict retrograde flow. Optionally, one or more elements (31, 32) can extend from the support frame/leaf structure to provide centering support and/or protection from the leaflet adhering to the vessel wall. In one embodiment, the centering support structure (164) comprises a second or third expandable frames (31, 32) attached to and extending from the proximal and/or distal ends of main valve structure and support frame. In another embodiment, one or more support elements extend outward from the valve support frame to engage the vessel wall to provide greater longitudinal stability.

The present inventions are directed to compositions and methods regarding the reprogramming of other cells (such as embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), MSCs, fibroblasts, hematopoietic stem cells, endothelian stem cells, adipocytes, chondrocytes, osteoblasts, osteoclasts and endothelial cells) into chondrogenic cells without introducing exogenous genes to the samples. In particular, the present inventions are directed to transducible materials that are capable of transducing into the biological samples but are not genes or causing genetic modifications. The present inventions also are directed to methods of reprogramming the path of biological samples or treating diseases using the tranducible compositions thereof.

The present invention relates to use of bisphosphonate formulations for the treatment and management of HIV/AIDS. The method of the invention comprises administering a formulation comprising an effective amount of a bisphosphonate that specifically inhibits the activity and/or decreases the number of monocytes and/or macrophages, thereby reducing or eliminating HIV reservoirs. The invention also provides a method of complementing an HIV antiviral therapy, such as the highly active antiretroviral therapy (HAART), with a bisphosphonate formulation to improve clinical outcome.

Methods for detecting an infection with Mtb in a subject are disclosed. The methods include detecting the presence of CD8 + T cells that specifically recognize an Mtb polypeptide. The methods include in vitro assays for detecting the presence of CD8 + T cells in a biological sample, and in vivo assays that detect a delayed type hypersensitivity reaction. The methods also include detecting Mtb polypeptides and polynucleotides.
摘要:
Methods for producing an immune response to Mycobacterium tuberculosis (Mtb) are disclosed herein. In several examples, the immune response is a protective immune response. In additional embodiments, methods are disclosed for inhibiting an infection with Mtb, preventing an infection with Mtb, or treating an infection with Mtb. Pharmaceutical compositions for the inhibition, prevention and/or treatment of tuberculosis are also disclosed.
摘要:
Provided herein are HIV-1 vaccines comprising a carrier and a population episensus antigen determined using the EpiGraph approach. Also provided are HIV-1 vaccines comprising a carrier, a population episensus antigen, and a tailored antigen. Also provided are methods of designing and producing an HIV-1 vaccine for a subject comprising designing vaccine antigens to optimally cover the diversity within a geographic area using an antigen amino acid sequence generated using the EpiGraph approach, and producing said designed vaccine antigen. Also provided are methods of inducing an effector memory T cell response comprising designing the one or more EpiGraph amino acid sequences, producing a vaccine comprising the one or more EpiGraph amino acid sequences and a vector, and administering the vaccine to a subject. Further provided are methods of treating HIV-1 in a subject comprising administering an effective amount of the described HIV-1 vaccines to the subject in need thereof.
摘要:
Disclosed herein are compounds that bind to the vesicular monoamine transporter 2 (VMAT2), pharmaceutical compositions comprising those compounds, and methods of treatment using said compounds and pharmaceutical compositions.
摘要:
A system and method for conducting a clinical trial of a medical treatment of human patients. The system uses an array of sensors in the patient's home for substantially continuously monitoring one or more objective functions of the patient. The monitored objective functions of the patient are compared against a baseline set of data for the monitored objective functions for the patient or a set of patients. The comparison includes detecting a trend of deviation between the one or more monitored objective functions of the patient and the baseline set of data. The trend of deviation can be correlated with an application or nonapplication of the medical treatment to the patient.
