Abstract: By way of example, a computing system may include an enclave or other similar secured memory location or process. When the system receives new content or data, it may classify the content as potentially harmful and initially render and display the content in the enclave. The user may then select portions of the content to enable or disable in a final version. The content may also be converted to a known “safe” equivalent format that always renders in the enclave. Enclave-rendered content may be signed by the enclave so that they can be considered “trusted” so long as the certificate remains valid and the content is correctly signed.

Abstract: This present invention discloses use of a chloroform/solvent mixture extraction at different solvent-to-feed ratios, followed by evaporation and extraction with ethyl acetate/water; followed by chromatography of the water phase in Teflon or other non-polar resin and Silica gel column chromatography for recovering of individual triterpene glycosides (saponins) of high purity from the freeze dried or spray dried cooking water or dried powderized tissues of the industrial processed sea cucumber Cucumaria frondosa. A resulting glycoside Frondoside A stimulates lysosomal activity of peritoneal macrophages, phagocytosis and oxidative burst in the macrophages at concentrations significantly less than for acute toxicity, hemolysis and sea urchin embryo toxicity.

Abstract: A process and apparatus for purifying water-insoluble particles is disclosed. The process comprises the steps of continuously recirculating a fluid aqueous suspension of the water-insoluble particles between a filtration system and a suspension reservoir; continuously conducting ultrafiltration of the recirculating suspension at the filtration system to separate an aqueous permeate containing the water-soluble impurities from the recirculating fluid aqueous suspension; continuously discharging the permeate generated by ultrafiltration; adding water to the recirculating fluid aqueous suspension undergoing ultrafiltration at approximately the same volumetric rate per hour as permeate is being discharged; monitoring the purity of the recirculating fluid aqueous suspension; and recovering the purified fluid aqueous suspension after the recirculating fluid aqueous suspension has reached a predetermined purity condition. An apparatus is also disclosed for carrying out the above process.
