摘要:
Fluidic adaptive lens devices, and systems employing such lens devices such as eyeglasses and zoom lens systems, along with methods of fabricating and operating such lens devices, are disclosed. In one embodiment, the fluidic lens device includes a first partition that is flexible and optically transparent and a second partition that is coupled to the first partition, where at least a portion of the second partition is optically transparent, and where a first cavity is formed in between the first partition and the second partition. The lens device further includes a first fluidic medium positioned within the cavity, the fluidic medium also being optically transparent, and a first component capable of controlling a parameter of the fluidic medium. When the parameter of the fluidic medium changes, the first partition flexes and an optical property of the lens is varied.
摘要:
The present invention provides compositions that are cell permeable antagonists of inositol polyphosphates. In addition, the invention provides methods for enhancing chloride ion secretion from a cell by contacting the cells with cell permeable antagonists of inositol polyphosphates. The invention also provides methods for enhancing chloride ion secretion in an individual by administering cell permeable antagonists of inositol polyphosphates to the individual. The invention additionally provides methods for alleviating a sign or symptom associated with cystic fibrosis in an individual by administering a cell permeable antagonist of inositol polyphosphates to the individual. The invention also provides compositions that are cell permeable agonists of inositol polyphosphates. In addition, the invention provides methods for decreasing chloride ion secretion from a cell by contacting the cell with cell permeable agonists of inositol polyphosphates. The invention also provides methods for decreasing chloride ion secretion in an individual by administering cell permeable agonists of inositol polyphosphates to the individual. The invention additionally provides methods for alleviating a sign or symptom associated with secretory diarrhea in an individual by administering cell permeable agonists of inositol polyphosphates to the individual.
摘要:
The present invention relates to a peptide, which specifically homes to the intracranial, early stage astrocytoma model that grows as islets and harbors co-opted tumor vessels in the brain. The peptide finds its use in targeted delivery of therapeutic substances to invasive brain cancer or metastatic brain lesions as such and in combination with conventional therapies, such as surgery and radiation, and anti-angiogenic therapies, and as a tool in diagnosis of, e.g., invasive brain cancer or metastatic brain lesions.
摘要:
The disclosure provides in vitro and in vivo methods for identifying Heparins and Heparinoids that modulate the activity of selectins. The disclosure also provides Heparins and Heparinoids that modulate the activity of selectins. The identification and isolation of these heparin formulations has the potential to mediate a wide variety of pathologies mediated by P- and/or L-selectin, including hematogenous metastasis, diseases associated with inflammation (e.g., asthma, arthritis, allergic dermatitis), ischemia-reperfusion injury, or other pathologies such as sickle cell anemia. Selectin inhibition can be achieved at plasma concentrations lower than those that cause excessive anticoagulation or unwanted bleeding in a human subject.
