  • Publication number: 20150368291
    Abstract: The present invention disclosed N-acetyl amino acid ester derivatives of betulin and the preparation method thereof, the method comprising the steps that in the presence of an alkaline substance, a catalyst and a racemization-inhibitor, the carboxyl group of N-acetyl amino acid is activated by a coupling agent; and then the activated N-acetyl amino acid is reacted with betulin via esterification reaction to obtain the N-acetyl amino acid ester derivative of betulin. The present invention provided a simple synthesis method to synthesize the N-acetyl amino acid ester derivatives of betulin by using betulin as a precursor compound and modifying the molecular structure of betulin. Such structural modification of betulin significantly enhances the anti-tumor activity of the betulin derivatives and therefore has important values.

  • Publication number: 20150363958
    Abstract: According to aspects of the present disclosure, certain areas of the display screen are logically considered to be “privileged.” For example, a user may run a utility program and selected areas of the wallpaper to be privileged. In another example, a utility scans the wallpaper looking for, say, a face or text and marks the location around the face or text as privileged. In any case, when an icon (or other visual information) needs to be placed on the display screen, the icon is preferentially placed at a location that does not overlap with the privileged areas. If no non-privileged area is available, then an alert can be sent to the user.

  • Publication number: 20150358587
    Abstract: Dissolution tester assembly that tests pharmaceutical tablets includes a frame that operatively supports a vessel having an interior into which a tablet is placed, a camera assembly supported by the frame and including a shaft having a hollow portion and an end that extends into the vessel interior, and an imaging system for imaging the tablet during the dissolution process to enable display of the images on a monitor. The imaging system includes a first camera positioned in the hollow portion of the shaft and oriented to image downward toward a bottom of the vessel, and/or a second camera positioned on the frame at a location directly below the vessel and oriented to image upward toward the bottom of the vessel. An attachment, such as a paddle for stirring or a basket for retaining the tablet, may be positioned at the end of the shaft in the vessel.

  • Publication number: 20150283290
    Abstract: Sterilized wound healing compositions comprise stabilized cyanoacrylate monomers homogenously mixed together with a naphthoquinone 2,3-oxide, including vitamin K oxides. The compositions are sterilized by irradiation, and the sterilized compositions are shelf stable such that their viscosity does not substantially increase following at least two years of shelf storage. The compositions may be used for closure of open wounds, and the compositions enhance the rate of wound healing relative to wounds not closed with the compositions.
