摘要:
Devices that include hosts having internal microcapillary networks are disclosed. The microcapillary networks are formed from interconnected passageways. The interconnected passageways may be formed by removing a fugitive material from a cured host material that forms the host. The resultant host material has many applications, including use as a microfluidic device in applications ranging from fluid mixing to structural repair.
摘要:
A laminate material may include a first flexible layer, and a self-healing composite layer in contact with the first flexible layer. The composite layer includes an elastomer matrix, a plurality of first capsules including a polymerizer, and a corresponding activator for the polymerizer. The laminate material may self-heal when subjected to a puncture or a tear.
摘要:
Disclosed is a hearing aid that includes a first component operable to receive an input and a second component operable to provide an output to at least one ear of a user of the hearing aid. The first component and the second component are electrically coupled together by a closed electrical circuit including at least one electrical conduction pathway formed by skin of the user between the first component and the second component. An electrical signal is transmitted from the first component to the second component with the closed electrical circuit. Communication between the first and second components can be one-way or two-way.
摘要:
A method of making a superconducting structure includes depositing a metal alkoxide on a surface of a metal and hydrolyzing the metal alkoxide on the surface to form a pinhole-free film. The metal is a superconductor. The metal alkoxide may be a compound of formula (I): M4(OPrn)16 (I); where M is zirconium or hafnium, and the purity of the compound is at least 97% as measured by NMR spectroscopy.
摘要:
The therapies described herein can be selectively lethal toward a variety of different cancer cell types and cancer conditions in a subject. The combination therapies described herein can be useful for the management, treatment, control, or adjunct treatment of diseases, where the selective lethality is beneficial in chemotherapeutic therapy, particularly where the disease is accompanied by elevated levels of NQO1.

摘要:
The invention provides polyelectrolyte inks comprising a solvent, a cationic polyelectrolyte, dissolved in the solvent, and an anionic polyelectrolyte, dissolved in the solvent. The concentration of at least one of the polyelectrolytes in the solvent is in a semidilute regime.
摘要:
The invention provides genetic suppressor elements that are derived from the apoptosis-related gene BCL2. The invention provides genetic suppressor elements that are capable of inhibiting BCL2 gene expression and BCL2-mediated suppression of apoptosis in mammalian cells. The GSEs provided by the invention are also useful for sensitizing cancer cells to the cytotoxic effects of chemotherapeutic drugs. The invention provides methods for identifying and obtaining such elements, and therapeutic methods of using such elements for treatment of cancer cells and animals bearing malignant tumors.
摘要:
Provided herein are methods, devices, kits, and articles of manufacture for detecting pregnancy-associated plasma protein-A (PAPP-A) in a biological sample, for instance a whole blood or serum sample obtained from a pregnant subject, and estimating gestational age (GA) based on the detection of PAPP-A, such that clinical or personal decisions informed by GA can be made without ultrasound.
摘要:
The invention relates to the use of a Mechano Growth Factor (MGF) polypeptide or a polynucleotide encoding an MGF polypeptide in the manufacture of a medicament for the prevention or limitation of myocardial damage in response to ischemia or mechanical overload of the heart by preventing or limiting apoptosis in the myocardium.
