Said preparation can improve hepatic cell degeneration, necrosis, intraheptic hemorrhage, fiber proliferation, and reduce pressure of portal vein in mammal. A preparation method of said preparation is disclosed.
摘要:
The present invention discloses a solenoid valve, it comprises: a movable core, provided with a flange at a lower end thereof; a driving assembly, in which the flange will abut against a bottom portion thereof and can move up against an upper portion thereof within a chamber of the driving assembly; a piston assembly, a central part of which seals a valve port of the solenoid valve, a periphery of which seals an annular chamber formed between the valve port and a valve body of the solenoid valve, the annular chamber being communicated to the inlet connection pipe, the piston assembly being disposed with a conducting hole at a center thereof, which is sealed by the bottom of the driving assembly; when opening the valve port, the flange of the movable core will first be moved to abut against the upper portion of the driving assembly, and then drive the driving assembly to move up in order to open the conducting hole, wherein since flow of fluid from an upper chamber above the piston assembly into an valve body outlet chamber below the piston assembly through the conducting hole via the valve port is larger than flow of fluid into the upper chamber from an inlet connection pipe of the solenoid valve, an upward force of pressure difference is generated on the piston assembly so that such upward force will enable the piston assembly to move up, thereby opening the valve port.

The disclosure provides a radio frequency calibration method for a mobile terminal, including: setting a parameter required for radio frequency calibration of the mobile terminal (201); obtaining PPDM values of power control signals and actual output power (P) values of the mobile terminal corresponding to the PPDM values by using different scanning steps according to linearity of a power curve, or, selecting, by using different selection intervals, part of PPDM values and P value corresponding to the part of PPDM values from calibration data obtained by fine scanning (202); and converting the obtained P values into PAGC values recognizable by the mobile terminal, and storing the PAGC values and the PPDM values corresponding to the PAGC values into a memory of the mobile terminal (203). The disclosure further discloses a radio frequency calibration apparatus for a mobile terminal. Through the solution of the disclosure, the finally obtained calibration data are more approximate to the memory space of the mobile terminal in length, so that the mobile terminal can transmit correct power by querying the calibration data when transmitting power to the outside, thereby reflecting the output characteristics of the mobile terminal more truly and improving the radio frequency output index, such as inner-loop power control, of the mobile terminal.

摘要:
The present invention relates to new compositions and methods useful for preventing, treating and diagnosing metastatic and/or invasive cancer and undesirable angiogenesis. For example, the invention relates to inhibitors of proteases that are specifically expressed in tumors, prodrugs activated in the tumor microenvironment and methods for using those inhibitors and prodrugs to inhibit angiogenesis and tumor cell invasion.
摘要:
Methods for detecting antibody dependent cellular cytotoxicity (ADCC) are described herein. The methods are label-free, and can be performed in real time on adherent cells. The methods can include, for example, (a) monitoring the impedance between electrodes on a non-conducting substrate that supports the growth of target cells in an assay medium; and (b) adding effector cells and an antibody that binds to the target cells to the assay medium; wherein any decrease in the impedance between the electrodes on the substrate following addition of the effector cells and the antibody is indicative of ADCC function having been effected in the assay medium.
摘要:
This invention relates to dietary compositions and to methods for modifying cellular metabolism, metabolic production of reactive oxygen species and the resulting level of reactive oxygen species. The invention is drawn to a composition comprising a combination of carnitine, lipoic acid and polyphenol, which has the effect of enhancing metabolism and reducing oxygen species at the same time. When the composition is fed to older animals, the animals will have improved metabolism at the cellular level and a reduction of oxidative stress. The invention is also drawn to a method of oral administration of carnitine, lipoic acid and polyphenol to a mammalian host, at an effective dose necessary to affect enhanced metabolic processes and reduced oxygen species in animals including humans.
