  • Patent number: 10314893
    Abstract: Emerging evidence indicates that diminished activity of the vasoprotective axis of the renin-angiotensin system, constituting angiotensin converting enzyme2 (ACE2) and its enzymatic product, angiotensin-(1-7) [Ang-(1-7)] contribute to pulmonary hypertension (PH). However, clinical success for long-term delivery of ACE2 or Ang-(1-7) would require stability and ease of administration to increase patient compliance. Chloroplast expression of therapeutic proteins enables their bioencapsulation within plant cells to protect from acids and gastric enzymes; fusion to a transmucosal carrier facilitates effective systemic absorption. Oral feeding of rats with bioencapsulated ACE2 or Ang-(1-7) attenuated monocrotaline (MCT)-induced increase in right ventricular systolic pressure, decreased pulmonary vessel wall thickness and improved right heart function in both prevention and reversal protocols.

  • Patent number: 10182948
    Abstract: The invention relates to a method and a device for making absorbent cores used in disposable hygiene pads, the method or device comprising three steps: (A) suctioning of wood pulp fibers mixed with super absorbent polymers into a net structure on a base tissue to form an absorbent core; (B) compressing and embossing absorbent material; and (C) shaping of the absorbent core. The method of the current invention can be used for making different kinds of absorbent pad products. While increasing the tear strength of the product, the method realizes and simplifies the process of making both the absorbent material and the hygiene pad utilizing the absorbent material on the same manufacturing line, and reduces the cost of making the absorbent pads. The absorbent core made by applying the method of the current invention has a new structure formed by super absorbent polymers and wood pulp fibers, wherein the structure enables the super absorbent polymers to be evenly distributed in between the wood pulp fibers.

  • Publication number: 20150209196
    Abstract: The invention provides a multilayer-structure absorbent core for a disposable absorbent article, and a method for preparing the absorbent core, wherein the absorbent core is compacted and formed by each layer; its surface presents a grid-shaped groove; the depth at the intersection point of the grid-shaped groove is bigger than that at the non-intersection point thereof. The invention adopts a new synchronous split-level process; that is, a linear grid-shaped trapezoid-shaped compaction mechanism, of which the height is smaller than that of a circular-platform structure, incompletely compacts the absorbent core and separates the absorbent core into numerous small convex spaces, while a circular-platform structure carries out the dot-shaped compaction for the absorbent core. Under the conditions that the liquid-absorption functions of a deflector layer and a reservoir layer are maintained, the movement of polymer water-absorption material is completely limited while the strength of a core body is enhanced.
