  • Patent number: 10371699
    Abstract: The invention describes a method for the identification of compounds which bind to a target component of a biochemical system or modulate the activity of the target, comprising the steps of: a) compartmentalizing the compounds into microcapsules together with the target, such that only a subset of the repertoire is represented in multiple copies in any one microcapsule; and b) identifying the compound which binds to or modulates the activity of the target; wherein at least one step is performed under microfluidic control. The invention enables the screening of large repertoires of molecules which can serve as leads for drug development.

  • Patent number: 10352132
    Abstract: An automatic downhole jetting system for advancing a string and automatically operating a valve mechanism upon contact with a restriction in a wellbore. A jetting unit receives a working fluid, and an activation unit slidably engaged with the jetting unit. The jetting unit includes the valve mechanism for controlling fluid flow out through angled jet ports or through the activation unit. The activation unit can move toward the jetting unit upon contact with a restriction in the wellbore. The activation unit activates the valve mechanism, thereby allowing fluid to flow past the activation unit to remove the restriction. Upon removal of the restriction, the fluid flow deactivates the valve mechanism, thereby closing fluid flow past the activation unit and continuing jetting operation.

  • Patent number: 10016509
    Abstract: Nutritional supplement compositions that may provide sub-cellular phytonutrient delivery include a carrier oil base containing at least one triglyceride and also contain at least one biologically active complex in the carrier oil base. The biologically active complex may include a non-covalent complex of a carbon-60 fullerene, phytonutrient compound, and a triglyceride from the carrier oil base. The phytonutrient compound may be chosen from compounds having the ability to form non-covalent complexes with six-membered aromatic rings of carbon-60 fullerene. Examples of such phytonutrient compound include, for example, phenolic compounds, polyphenolic compounds, phenolic acids, flavonoids, terpenoids, tannins, stilbenes, curcuminoids, coumarins, lignans, quinones, phenylethanoids, carotenoids, astaxanthin, zeaxanthin, or coenzyme Q10. The nutritional supplement compositions may include multiple biologically active complexes in which the phytonutrient compounds are derived from olives, algae, or both.
