  • Publication number: 20190015350
    Abstract: Symmetrically and asymmetrically branched homopolymers are modified at the surface level with functional groups that enable forming aggregates with a taxane, such as, paclitaxel and derivatives thereof, which are water insoluble or poorly water soluble. The aggregates are formed by interaction of a taxane and a homopolymer. Such aggregates improve drug solubility, stability, delivery and efficacy.

  • Publication number: 20190010550
    Abstract: The present invention provides a method for detecting transplantation failure of a transplanted organ or cells which comprises detecting a donor-positive but recipient-negative DNA marker in the recipient's plasma using pyrophosphorolysis activated polymerization. Because of the high sensitivity, specificity and selectivity of pyrophosphorolysis activated polymerization, transplantation failure can be detected at early stages and treatment can be initiate earlier.

  • Publication number: 20180031542
    Abstract: A method of evaluating an action includes (1) obtaining a first stem-cell data related to a subject before performing the action, (2) performing the action on the subject, (3) obtaining a second stem-cell data related to the subject after performing the action, and (4) identifying the effect of the action on the subject based on the first stem-cell data and the second stem-cell data. The subject may be a human or an animal. The action may be taking a drug or taking a nutrient or dietary supplement, which may include fucoidan. Each of the first and second stem-cell data may include the count of a type or types of stem cells and/or the percentage of the type or types of stem cells and may be obtained by the same method including counting cells using a cell counter or cell counting device such as flow cytometer.

  • Publication number: 20180024122
    Abstract: A method of obtaining stem cells includes (1) a subject (such as a human or an animal) taking or being subjected to an action, (2) after the subject taking or being subject to the action, the subject waiting for a predetermined time interval (such as between 30 minutes and 2 hours), (3) after the subject waiting for the predetermined time interval, taking a tissue sample (such as a peripheral blood of the subject) from the subject, and (4) collecting the stem cells from the tissue sample. The step of the subject taking or being subjected to the action may include the subject taking a herb medicine or an object containing fucoidan. The stem cells may be configured for a dental implant surgery. The stem cells may include a CD9(+), CD349(+) cell between 0.1 and 6.0 micrometers in size and/or a Lgr5(+) cell between 0.1 and 6.0 micrometers in size.
