摘要:
The invention relates to an enteric-coated capsule containing cationic nanoparticles for oral insulin delivery, in particular to a type of cationic nanoparticle including a polycationic and mucoadhesive polymer and a biodegradable polymer, wherein each of the nanoparticles has positive surface charge and enhanced permeability for paracellular insulin delivery; the enteric-coated capsule further includes a pH-sensitive polymer as the coating. The enteric-coated capsule containing cationic nanoparticles, when being orally administered to a subject, are configured to prevent the acidic degradation of the active substance such as insulin before being released from said cationic nanoparticles to a specific absorption site along the gastrointestinal tract.

The present invention discloses the pH-sensitive nanoparticles composed of pH-sensitive polymer, hydrophobic material, internal stabilizer, external stabilizer content and insulin drug. The present invention also includes a method for preparation of pH-sensitive nanoparticles, in particular, a multiple emulsions solvent evaporation method. The pH-sensitive nanoparticles of the present invention show good pH-sensitive property with 100-300 nanometer particle size. Significant decrease in blood glucose level is observed in streptozotocin (STZ)-induced diabetic rats and the bioavailability of insulin is more than 10% after oral administration of the insulin-loaded pH-sensitive nanoparticles.

Message management and classification techniques are described. In one or more implementations, a message received from a sender for delivery via a user account is examined to extract one or more features of the message. A determination is then made as to whether the message corresponds to one or more categories based on the extracted features, the categories usable to enable features to be applied to the message in a user interface.

One or more techniques and/or systems are provided for defining a message behavior profile for a sender, which may be used to categorize messages from the sender. A message behavior profile may be defined based upon, for example, message distribution behavior of the sender (e.g., volume, frequency, variance in content amongst messages sent to recipients, etc.); recipient interactions with messages from the sender (e.g., message read rates, message response rates, etc.); unsubscription options comprised within messages from the sender; and/or other factors. In this way, the message behavior profile and/or features extracted from a message may be used to categorize a message from the sender (e.g., newsletter, commercial advertisements, alert, social network etc.). Categorized messages may be organized into folders, displayed or hidden within views, and/or processed based upon their respective categorizations.

The invention discloses an electronic terminal and a ringtone prompt method for the electronic terminal. A control module of the electronic terminal instructs a ringtone sound source module to play a test ringtone signal, and instructs a ringtone channel switch system to switch all sound channels one by one to output the test ringtone signal; a sound collection module collects an exterior sound signal while each channel is outputting the test ringtone signal and feeds it back to a signal processing module; the signal processing module processes the intensity of the test ringtone signal therein; the control module determines the output channel of a prompt ringtone signal according to the processing result of the collected signal, instructs the ringtone channel switch system to switch to the determined output channel, and instructs the ringtone sound source module to play the prompt ringtone signal.

The present invention provides a method for manufacturing a semiconductor structure, comprising: forming a first contact layer on an exposed active region of a first spacer; forming a second spacer at a region of the first contact layer close to a gate stack to partially cover the exposed active region; forming a second contact layer in the uncovered exposed active region, wherein when a diffusion coefficient of the first contact layer is the same as that of the second contact layer, the first contact layer has a thickness less than that of the second contact layer; and when the diffusion coefficient of the first contact layer is different from that of the second contact layer, the diffusion coefficient of the first contact layer is smaller than that of the second contact layer. Correspondingly, the present invention also provides a semiconductor structure. The present invention is beneficial to the suppression of the diffusion of corresponding compositions from the contact layers into the channel region, reduction of the short channel effects, and improvement of the reliability of the semiconductor structure.
