摘要:
Disclosed is the FRIL family of progenitor cell preservation factors and nucleic acids encoding the same. FRIL family members preserve progenitor cells both in vivo and ex vivo. FRIL family members find use as therapeutics for alleviating and/or reducing the hematopoietic progenitor cell-depleting activity of many cancer therapeutics. FRIL family members are also useful for isolating rare, primitive progenitor cells.
摘要:
Described is a circuit arrangement for detection of a tone whose presence indicates insertion of a headphone plug into a jack. The circuit includes a receptacle having contacts configured to receive a plug inserted into the receptacle, a current sense circuit, an amplifier coupled to the current sense circuit and a band pass filter coupled to an output of the amplifier, the band pass filter configured to pass a signal having a frequency in a range of about 2 Hz to 20 Hz. Circuitry converts the passed signal into a digital signal to provide an input signal to a controller to indicate that a headphone plug was inserted into the receptacle.

摘要:
Secreted FXYD family proteins are expressed by intestinal mucosa and/or associated tissues to regulate cell production in intestinal crypts in response to tissue damage. Such tissue damage may arise from disease, exposure to injurious chemicals (e.g., due to poisoning, chemotherapy, chemical weapons), or exposure to injurious radiation (e.g., due to nuclear power accidents, radiological weapons, radiation therapy). Because these proteins are secreted in response to epithelial tissue damage, some of them are implicated in tissue repair response or an inflammatory response which prolongs or exacerbates the tissue damage. Examples of these proteins include FXYD 3, FXYD 4, and FXYD 5. Diagnostic methods based upon the role of the FXYD proteins in epithelial tissue damage are disclosed. Also provided are antibodies raised against the FXYD family proteins, a kit for detecting at least an epitope of a polypeptide, a method of producing an antibody raised against an epitope of a polypeptide, and a method of diagnosing damage to an epithelial tissue.

The present invention relates to a class of fluorescent, organic nanofibrils, and particularly the films comprising entangled piling of these nanofibrils exhibiting effective quenching of their fluorescence upon exposure the vapor of explosives. The invention also relates to a sensor and a method for sensing the explosives vapor and other volatile organic compounds, including the explosives taggants through the modulation of the fluorescence of the nanofibril film and the electrical conductivity of the nanofibrils. The invention also relates to a development of synthetic methods, protocols and techniques that leads to production of various arylene-ethynylene macrocycle (AEM) molecules, which consist of a shape-persistent, toroidal scaffold in planar conformation, with minimal ring strain and highly tunable ring sizes (from 0.5 nm to above 10 nm). The invention also relates to an approach to optimization of the one-dimensional molecular arrangement along the long axis of the nanofibril, which provides increased exciton (excited state) migration (via cofacial intermolecular electronic coupling) and charge transport (via pi-electronic delocalization). A combination of long-range exciton migration and efficient charge transport makes the nanofibrils ideal as sensory materials for detecting explosives and other volatile organic compounds through both optical and electrical sensing mechanisms.

A battery compartment assembly includes a housing and a lid configured to be removably attached to the housing. The lid includes a pair of hinges that engage a corresponding pair of openings in the housing, and a latch that engages a ridge on the housing when the lid is in the closed position. The lid also includes a pair of contacts that extend from the lid to mate with connectors of a control unit to be powered by the batteries in the assembly. A spring is included in the housing for connecting to a positive terminal of a first battery and a negative terminal of a second battery.

The system is further configured for at least one of defining looks, including shot templates, that correspond to particular settings on the production control switcher or settings of parts of the production control switcher; defining sequences of the looks or assigning individual looks to control elements on a computer of the computers; transmitting the looks across the network; and translating of a single look into one or more standard editor commands, and transmitting the commands to the production control switcher.
摘要:
A magneto-striction based, passive optical current sensor is provided that is located at high voltage and communicates to ground level via an optical fiber. The optical current sensor includes a ferromagnetic core, a modulator of magnetostrictive material, e.g. Terfenol-D in a preferred embodiment, that responds to the magnetic field, and two or more matched fiber Bragg gratings that convert this response into a wavelength modulated optical signal that is transmitted via an optical fiber to ground level electronics. To linearize the output of the optical current sensor, the optical sensor includes arrangements to provide both mechanical and magnetic bias to the modulator.
