摘要:
The invention provides for novel 2-Deoxyadenosine compounds, which can treat HIV infection at low cytotoxicity values. Substitution at the 4′-position provided compounds which demonstrated low cytotoxicity values in an ATP-based cytotoxicity assay.
摘要:
It is disclosed herein that expression of microRNA-26 is decreased in hepatocellular (HCC) tumor tissue relative to non-cancerous tissue, and that a low level of microRNA-26 is associated with a poor clinical outcome. It is also disclosed herein that a low expression level of microRNA-26 is correlated with a favorable response to interferon (IFN)-α therapy in HCC patients. Thus, provided herein is a method of predicting the clinical outcome of a patient diagnosed with HCC comprising detecting the level of microRNA-26 expression in a sample obtained from the patient. Also provided is a method of selecting a patient diagnosed with HCC as a candidate for IFN-α therapy, comprising detecting the level of microRNA-26 expression in a sample obtained from the patient. A method of identifying therapeutic agents for the treatment of HCC, comprising screening candidate agents in vitro to select an agent that increases expression of microRNA-26 in HCC cells are also provided. Further provided are methods of treating a patient diagnosed with HCC and expressing a low level of miR-26, wherein treatment comprises IFN-α therapy.
摘要:
Cytotoxic effects associated with ground fractured silica-containing minerals and silicates, including asbestos, are prevented by coating the silica-containing minerals and silicates with an aqueous solution containing an aqueously compatible silane coupling agent so that a monomolecular film is formed on the surface of the silica-containing minerals and silicates.

Embodiments herein report compositions, methods and uses for dengue-4 (DENV-4) virus constructs. Some embodiments concern a composition that includes, but is not limited to, DENV-4 virus constructs alone or in combination with other constructs, can be used in a vaccine composition to induce an immune response in a subject. In certain embodiments, compositions can include constructs of more than one serotypes of dengue virus, such as dengue-1 virus, dengue-2 virus, or dengue-3 virus in combination with DENV-4 virus constructs disclosed herein. In other embodiments, DENV-4 constructs disclosed herein can be combined in a composition with other flavivirus constructs to generate a vaccine against more than one flavivirus. Other embodiments provide methods and uses for DENV-4 virus constructs in vaccine compositions that when administered to a subject induce an immune response in the subject against DENV-4 that is improved by modified constructs compared to other vaccine compositions.
摘要:
Substituted carbamates of tricyclic compounds which have a cyclic sulfer atom, provide highly potent and selective cholinergic agonist and blocking activity are useful as pharmaceutical agents. Cholinergic disease are treated with these compounds such as glaucoma, Myasthenia Gravis, Alzheimer's disease. Methods for inhibiting esterases, acetylcholinesterase and butyrylcholinesterase are also provided.
摘要:
The present invention relates to cell medium developed to support long term multiplication and permanent establishment of a cell line of human liver epithelial cells. The medium may contain an effective cell growth promoting amount of calcium ions; an effective cell growth promoting amount of glucose; an effective amount of insulin to aid cells in glucose uptake; an effective cell growth promoting amount of hydrocortisone; an effective amount of epidermal growth factor to bind epidermal growth factor receptors on cells; an effective amount of transferrin to increase DNA synthesis in cells; an effective amount of cholera toxin to increase DNA synthesis in cells; an effective amount of triiodothyronine to increase DNA synthesis in cells; and an effective growth promoting amount of mammalian hormones and mitogenic factors, including lipoprotein, cholesterol, phospholipids and fatty acids.
