Abstract:
This invention pertains to disulfide-linked conjugates of therapeutic agents containing at least one thioamide group with polymer comprising at least one thiol group, so as to provide a controlled release pharmaceutical composition for administration to animals for the prophylaxis or treatment of various conditions or diseases. The therapeutic agent conjugate may comprise an inactive or weakly active prodrug form which may be converted into the original therapeutic compound by the natural action of reducing agents in vivo . The composition may comprise a mixture of polymers each with a different thioamide-containing agent attached, or a polymer conjugated with a mixture of thioamide-containing agents. Modified properties of the therapeutic compound potentially provided by the polymer itself, as well as by other compounds also appended to the polymer, include but are not limited to greater water solubility, longer in vivo half-life (due to larger size of the conjugate), slower release from a sustained-release depot (due to larger size of the conjugate), better oral bioavailability and tissue-specific targeting.
Abstract:
Long term culture of resting T lymphocytes. The present invention provides methods and compositions for maintaining resting, mature T lymphocytes (cells) for long term in the absence of mitogens, antigens, or stimulatory cytokines, in which the T cells maintain their ability to respond to mitogens and allogeneic cells. T cells cultured under such conditions can be used as target cells for retroviral vector-mediated gene transfer and implemented in certain gene therapy applications. The culturing conditions described herein allow for the continuous availability of T lymphocytes for various pharmacological, diagnostic, gene therapy, and experimental purposes, and can be utilized for any application requiring non-stimulated T lymphocytes. In specific examples, umbilical cord blood and peripheral blood T lymphocytes and endothelial-like adherent monocytes are cultured in DMEM, 2 % 2-mercaptoethanol containing either 20 % horse serum, or RPMI 2 % 2-ME containing 10 % fetal calf serum supplemented with basic fibroblast growth factor for up to three months.
Abstract:
An interactive graphic computer methodology has been developed allowing a surgical resident or trauma surgeon to utilize a series of body images to record the location, type, complexity and physiology severity of trauma injuries via an interface device such as a mouse controller. The methodology incorporates, as a primary machine/human interface, a plurality of color graphic screens which share a common relational data base. Those graphic screen images include: (1) skin and superficial anatomy (for location of sites and types of injuries or burns), (2) skull, facial bones and CNS neurologic exam with automated calculation of GCS, (3) skeletal and joint anatomy (for orthopedic injuries), (4) spinal cord injury exam, (5) thoraco-abdominal viscera, (6) liver, pancreas and biliary tract, (7) retroperitoneal organs and structures, (8) vascular anatomy, (9) lung and tracheo bronchial tree. After data entry, injuries can be grouped for reporting and coding (i.e., fractures, organ injuries, lacerations, etc.). For specific types of injury, severity criteria are determined, therapeutic management guidelines estimated and state of the art therapeutic suggestions and cautions provided.
Abstract:
A method of synthesis of new and useful single-stranded DNAs which have a stem-loop configuration (ss-slDNA). The method is an DOLLAR i (in vivo) or an in vitro synthesis. Replicating vehicles which produce these ss-slDNAs. The ss-slDNAs are described. Uses for these slDNAs are disclosed. They can be used for introducing random mutations, they lend themselves for replication by a variant of the PCR method. They can also be used for regulating gene function. Other uses are disclosed.
Abstract:
The invention relates to compositions and methods to isolate nucleic acids, and the identification of polyadenylation sites in a gene of interest.
Abstract:
A method, device, and system is disclosed to detect whether one or more analytes of interest are present on a cell or cell organelle surface. The device includes a cartridge that includes a channel having a bottom surface that includes at least one immobilized patch of reagents with a binding affinity for one of the analytes of interest. The method introduces a fluid containing at least one cell or cell organelle into the channel, measures the velocity of at least one cell or cell organelle individually over each of the immobilized patches at a plurality of defined time intervals or distances for each patch, discards some of the largest velocity measurements, and compares the mean value of the remaining velocity measurements to a control value to determine whether the analyte of interest is present on the surface of the cell or cell organelle.
Abstract:
The present invention relates generally to dental diseases, caries and periodontal disease. More specifically, the invention relates to Lactoferrin and PAK fusion peptides (PAK-LF), along with therapeutic, diagnostic and research uses for these polypeptides. The present invention also provides methods of treating dental diseases, caries and periodontal disease.
Abstract:
Disclosed herein are compositions and methods for the treatment and/or prevention of pathological conditions associated with ischemia/reperfusion injury and/or hypoxic injury of myocardial cell or tissue.
Abstract:
This application discloses methods for treating, preventing and/or alleviating the symptoms of type II diabetes and diabetes-related disorders or complications. The invention provides a novel approach to treating and managing disorders and symptoms related to elevated plasma glucose concentrations and insulin resistance, characterized by few side effects and low toxicity. In particular, the invention provides 2-hydroxy-benzoic anilide compounds and derivatives, and compositions thereof, which can control blood- glucose and increase insulin sensitivity by reducing plasma glucose concentration and cellular energy efficiency.
