摘要:
A hair care composition which comprises a plurality of cross-linked polymer particles, said polymer being the polymerization product of at least two monomer units selected from the group consisting of monoalkenyl aromatic compounds, alkyl esters derived from a saturated alcohol and acrylic or methacrylic acid, and vinyl esters of an aliphatic carboxylic acid is useful for controlling sebum on hair without providing undue whiteness to the hair.
摘要:
A composition which comprises (A) a plurality of cross-linked polymer particles, said polymer being the polymerization product of at least two monomer units selected from the group consisting of monoalkenyl aromatic compounds, alkyl esters derived from a saturated alcohol and acrylic or methacrylic acid, and vinyl esters of an aliphatic carboxylic acid; and said cross-line polymer particles being loaded with (B) an active ingredient, the weight ratio of the active ingredient (B) to the polymer particles (A) being from 0.05 to 50:1, is useful to release the active ingredient over an extended period of time while controlling sebum on skin and hair.

摘要:
Provided are polypeptides having the effects of inhibiting hepatitis B virus x protein (HBx) and polynucleotides encoding the peptides. Also provided are peptidomimetics, functional fragments and functional variants thereof, as well as the encoding genes thereof. The polypeptides and peptidomimetics can be used for the treatment and prevention of liver diseases resulted from hepatitis B virus infection, including hepatitis, cirrhosis and liver cancer.
摘要:
A smart card with two read-write modes includes antenna layer, and an antenna and a chip module circuits on the antenna layer, wherein the antenna and the chip module circuit are electrically connected via an elastic conductive device. The invention also provides a manufacturing method of the aforesaid smart card with two read-write modes, which includes steps of: embedding an antenna on a back side or a front side of an antenna layer; after completing embedding on the antenna layer, add bedding sheets, printed sheets and protection films respectively above and underneath the antenna layer, then laminating to obtain a card base carrier; cutting card from the treated whole-sheet card base carrier to obtain a card base, and milling slots on the obtained card base, then finally encapsulating.
摘要:
A method, device, and system for communication signal transmission are provided, which relate to the field of communications, so as to improve reception performance of the network. The method includes dividing, by a multi-frequency receiver, Radio Frequency (RF) signals by frequency bands received from an antenna to obtain RF signals of different frequency bands; sending a first group of RF signals of a predetermined frequency band to an RF unit so that the RF unit converts the received first group of the RF signals of the predetermined frequency band into first baseband digital signals and sends the first baseband digital signals to a baseband processing unit; and converting a second group of the RF signals of the predetermined frequency band into second baseband digital signals and sending the second baseband digital signals to the baseband processing unit by using a digital baseband interface.
