  • Patent number: 11963970
    Abstract: The present disclosure discloses a preparation method of ginseng composition with high ginsenoside bioavailability. The composition is composed of ginseng powder of 250 meshes or more and ?-cyclodextrin, and the mass ratio of the ginseng powder to the ?-cyclodextrin is 1:0.05. Results show that when ?-cyclodextrin is used as a solid dispersant and added to the 1000-mesh ginseng powder at a mass ratio of 5%, the total dissolution amount is maximum; and furthermore, animal experiments (SD rats) show that the area under the plasma drug concentration-time curve (AUC0-48 h) after 48 h of ginseng powder ingestion is maximum, indicating that in-vivo bioavailability of the ginseng powder is the highest. The method of this application can effectively inhibit the aggregation of the ultra-finely pulverized 1000-mesh ginseng powder by adding the ?-cyclodextrin, thus significantly improving the total dissolution amount of ginsenoside.

  • Publication number: 20240120363
    Abstract: A self-aligned plug may be formed between deep trench isolation (DTI) etching cycles. Accordingly, etch depth in areas of a pixel sensor with large CDs (e.g., at an X-road) is reduced, which prevents trench loading. As a result, a floating diffusion (FD) region, associated with photodiodes of the pixel sensor, is not damaged during the DTI etching cycles. Reduced chances of damage to the FD region improves performance of the pixel sensor and prevents electrical shorts and failures, which increases yield and conserves time and raw materials used in forming the pixel sensor.
