Abstract:
This invention provides a class of androgen receptor targeting agents (ARTA). The agents define a new subclass of compounds, which are selective androgen receptor modulators (SARM). Several of the SARM compounds have been found to have an unexpected androgenic and anabolic activity of a nonsteroidal ligand for the androgen receptor. Other SARM compounds have been found to have an unexpected antiandrogenic activity of a nonsteroidal ligand for the androgen receptor. The SARM compounds, either alone or as a composition, are useful for a) male contraception; b) treatment of a variety of hormone-related conditions, for example conditions associated with Androgen Decline in Aging Male (ADAM), such as fatigue, depression, decreased libido, sexual dysfunction, erectile dysfunction, hypogonadism, osteoporosis, hair loss, anemia, obesity, sarcopenia, osteopenia, osteoporosis, benign prostate hyperplasia, alterations in mood and cognition and prostate cancer; c) treatment of conditions associated with Androgen Decline in Female (ADIF), such as sexual dysfunction, decreased sexual libido, hypogonadism, sarcopenia, osteopenia, osteoporosis, alterations in cognition and mood, depression, anemia, hair loss, obesity, endometriosis, breast cancer, uterine cancer and ovarian cancer; d) treatment and/or prevention of acute and/or chronic muscular wasting conditions; e) preventing and/or treating dry eye conditions; f) oral androgen replacement therapy; g) decreasing the incidence of, halting or causing a regression of prostate cancer; and/or h) inducing apoptosis in a cancer cell.
Abstract:
Polypeptide and peptide fragments of CD9 as well as antibodies raised against those fragments of CD9. Uses of polypeptide and peptide fragments of CD9, antibodies, and inhibitors of CD9-related kinases include modifying cell behavior such as adhesion, motility, proliferation, survival, cell spreading, invasiveness, pericellular FN matrix assembly, and cell-to-cell interaction.
Abstract:
The presently disclosed subject matter involves methods of predicting response in a subject to treatment for a disease with a VEGF targeted therapeutic, and for evaluating and/or monitoring treatment for a disease involving use of a VEGF targeted therapeutic in a subject. Such methods involve determining a level of ANGPTL4 expression in a biological sample from the subject; and comparing the level of ANGPTL4 expression in the sample with a reference, wherein the subject is predicted to be a likely responder or non-responder based on the ANGPTL4 expression in the sample relative to the reference. Administering a VEGF targeted therapeutic to the subject is initiated or continued when the subject is predicted to be a likely responder.
Abstract:
Tooth remineralization compositions are provided for preventing and treating tooth decay and dental erosion in a patient. The composition comprises a remineralizing agent encapsulated in a polymer. In various embodiments, the remineralizing agent may be in a polymeric chitosan microspheres and/or nanospheres and the remineralizing agent comprises calcium and/or phosphate. Methods of preparation and use of the remineralization compositions are also disclosed.
Abstract:
A catalyst is provided for the two electron reduction of oxygen. The catalyst can be reversible or near-reversible. The catalyst comprises a gold and a cobalt coordination complex, i.e., N,N'-bis(salicylidene)ethylene- diaminocobalt (II) (cobalt salen) or a derivative thereof. The cobalt coordination complex can be polymerized to form a film, for example, via electropolymerization, to cover a gold surface. Also provided are metal-air batteries, fuel cells, and air electrodes that comprise the catalyst, as well as methods of using the catalyst, for example, to reduce oxygen and/or produce hydrogen peroxide.
Abstract:
The present invention is a method and kit for determining responsiveness of a subject to treatment with a Type I interferon based upon the expression of gene signatures shown to be stimulated by interferon. A method for testing the propensity of a test compound to induce a Type I interferon response is also provided.
Abstract:
A process of producing magnesium metal includes providing magnesium carbonate, and reacting the magnesium carbonate to produce a magnesium-containing compound and carbon dioxide. The magnesium-containing compound is reacted to produce magnesium metal. The carbon dioxide is used as a reactant in a second process. In another embodiment of the process, a magnesium silicate is reacted with a caustic material to produce magnesium hydroxide. The magnesium hydroxide is reacted with a source of carbon dioxide to produce magnesium carbonate. The magnesium carbonate is reacted to produce a magnesium-containing compound and carbon dioxide. The magnesium-containing compound is reacted to produce magnesium metal. The invention also relates to the magnesium metal produced by the processes described herein.
Abstract:
Materials prepared from polydienes, such as poly(cyclohexadiene), and hydrophilic polymers, such as poly(alkylene oxide), are described. Methods of making the materials and their use in fuel cell membranes, batteries, breathable chemical-biological protective materials, and templates for sol-gel polymerization are also provided. The materials can be crosslinked and sulfonated, and can include copolymers and polymer blends.
Abstract:
Provided herein are steroidal compounds that are androsta-5,7-dienes or a pregna-5,7-dienes and ultraviolet B (UVB) conversion products thereof which includes pharmaceutical compositions of the steroidal compounds. Also provided is a method for producing hydroxylated metabolites of cholecalciferol via the P450scc (CYPl IA 1) or CYP27B 1 enzyme systems and the hydroxylated metabolites so produced. In addition, a method for inhibiting proliferation of either a normally or abnormally proliferating cell by contacting the cell with any of the compounds described herein. A related method is provided of treating a condition associated with the proliferating cell such as a cancer, a skin disorder, a defect in cell differentiation, cosmetic, prophylaxsis, or healthy cell maintenance.
Abstract:
The present invention describes a novel mechanism of adhesion by flagellated Gram-negative bacteria such as enterotoxigenic Escherichia coli (ETEC), where the bacteria secretes a protein, EtpA which binds to the conserved region of the flagellin protein located at the tip of the flagella. The present invention also discloses that EtpA-mediated interaction and intestinal colonization require interaction with flagellin. Also disclosed herein is a vaccine composition that can be used for either active or passive immunization of mammals for the prevention or treatment of infections caused by flagellated Gram-negative bacteria.
