摘要:
There is disclosed a process of treating or alleviating the symptoms of pathological conditions in which bone density is decreased, which comprises inhibiting, in a mammalian patient suffering from such a condition, the formation in vivo of a tertiary complex of IL-11, its cell surface membrane receptor and the cell surface glycoprotein gp130. Examples of such substances are recombinant soluble IL-11 receptor mutants modified, as compared with native IL-11 receptor, at their gp130 binding site, and peptides which can interact with IL-11. The process of the invention not only inhibits bone resorption and hence bone loss, but also increases the process of bone formation to increase bone density.

The present invention relates to novel classes of compounds which are inhibitors of interleukin-1β converting enzyme (“ICE”). This invention also relates to pharmaceutical compositions comprising these compounds. The compounds and pharmaceutical compositions of this invention are particularly well suited for inhibiting ICE activity and consequently, may be advantageously used as agents against interleukin-1-(“IL-1”), apoptosis-, interferon-γ inducing factor-(IGIF), interferon-γ-(“IFN-γ”) mediated diseases, excess dietary alcohol intake diseases, or viral diseases, including inflammatory diseases, autoimmune diseases, destructive bone disorders, proliferative disorders, infectious diseases, and degenerative diseases. This invention also relates to methods for inhibiting ICE activity and decreasing IGIF production and IFN-γ production and methods for treating interleukin-1, apoptosis- and interferon-γ-mediated diseases using the compounds and compositions of this invention. This invention also relates to methods of preparing the compounds of this invention.
摘要:
Acoustic energy is used to control motion in a fluid. According to one embodiment, the invention directs acoustic energy at selected naturally occurring nucleation features to control motion in the fluid. In another embodiment, the invention provides focussed or unfocussed acoustic energy to selectively placed nucleation features to control fluid motion. According to one embodiment, the invention includes an acoustic source, a controller for controlling operation of the acoustic source, and one or more nucleation features located proximate to or in the fluid to be controlled.
摘要:
Digital to analog converter circuits and methods are provided for producing an analog output voltage indicative of a digital input signal with at least partial insensitivity to error gradients. Described are split-core resistive elements, which include a plurality of one-dimensional or multi-dimensional resistive strings, that may be used to reduce or substantially eliminate the effects that error gradients have on the linearity of the analog output voltages of a resistive string or interpolating amplifier DACs. The resistor strings that make up the split-core resistive elements are configured in such a manner that combining respective output voltages from each of the resistor strings results in an analog output voltage that is at least partially insensitive to the effects of error gradients.
摘要:
Methods and apparatus are presented that facilitate electrophoresis of prior-cast, hydratable separation media, usefully immobilized pH gradient (IPG) strips. The method exploits the swelling of prior-cast, hydratable separation media upon rehydration to help lodge the media in an enclosing member that permits spaced electrical communication with the enclosed separation media. The electrical communication permits a voltage gradient to be established in the enclosed separation medium sufficient to effect separation of analytes therein. Cassettes, buffer cores, electrophoresis systems and kits are presented for effecting the methods of the invention.
摘要:
Techniques of increasing drive strength and reducing propagation delays of a digital logic circuit through the use of feedback are presented. Logic circuitry operative to receive an input signal of the digital logic circuit and a delayed version of an output signal of the digital logic circuit turns “ON” a supplemental drive transistor for a digital state transition of the output signal. The supplemental drive transistor provides supplemental drive current to the digital logic circuit during the output signal digital state transition, thus advantageously reducing propagation delay and increasing fan-out capability. The logic circuitry turns “OFF” the drive transistor once the output signal digital state transition is complete.
摘要:
Nucleic acid molecules are described which encode polypeptides having the enzymatic activity of a fructosyltransferase. Also, vectors, host cells and transgenic plants are described which contain such nucleic acid molecules. Furthermore, processes for producing polyfructose, particularly that of the inulin type, using the hosts described and/or the fructosyltransferase produced by them are described.
