Publication number: 20230172088Abstract: The new plant variety ‘Pheasant Tail’ is part of the long leaves sansevieria varieties. It can reach 90 cm in length, with an average of approximately 4-7 leaves per plant. The new plant variety ‘Pheasant Tail’ is cylinder shaped, the arrangement of the leaves is in the form of a rosette. Leave colors are very different compared to its parent variety (‘Wintergreen’), but like its parent variety the new plant variety ‘Pheasant Tail’ shows also variegated bands on the leaves with no distinguishable margins and produces more leaves per rosette. Additionally, new plant variety ‘Pheasant Tail’ shows, unlike the parent variety, high resistance to anthracnose disease caused by C.sansevierae which gives the new variety a greater competitive advantage as well as its sister variety ‘Spearmint’ (Patent No. U. S. 32,333).Type: ApplicationFiled: November 27, 2021Publication date: June 1, 2023Applicant: UNIVERSIDAD DE COSTA RICAInventor: Arturo BRENES ANGULO

Patent number: 10562958Abstract: A method for producing injectable pharmaceutical formulations of blood-derived protein materials includes the steps of fractioning the source material in a polymer/salt aqueous two-phase system in the presence of phenol, purifying the top phase of the system by means of precipitation with caprylic acid and purifying the bottom phase by means of thermocoagulation, increasing the purity of the materials in both phases through chromatography, removing viral particles by means of the nanofiltration of both preparations, and formulating, stabilizing, and packaging the resulting materials.Type: GrantFiled: April 8, 2011Date of Patent: February 18, 2020Assignee: UNIVERSIDAD DE COSTA RICAInventors: Álvaro Segura Ruiz, Mariángela Vargas Arroyo, Guillermo León Montero, Mauren Villalta Arrieta, María Herrera Vega, Yamileth Angulo Ugalde

Patent number: 10278949Abstract: A biotechnology process that employs membrane technology for obtaining an extract rich in tannins of ellagic acid from blackberries (Rubus spp.) and from other fruits that contain these compounds, as well as to the extract obtained using this method. The method is essentially based on baromembrane technologies that allow mechanical separation and effective fractionation between the polyphenol compounds, by interactions between the physico-chemical properties thereof, the material of the membrane and the molar mass of same, thereby allowing enrichment of a fraction of the natural extract with ellagic acid tannins and modification of the content thereof in terms of anthocyanins and other compounds such as sugars and acids.Type: GrantFiled: May 11, 2012Date of Patent: May 7, 2019Assignees: UNIVERSIDAD DE COSTA RICA, CENTRO INTERNACIONAL DE COOPERACION EN INVESTIGACION AGRICOLA PARA EL DESARROLLO, CIRAD, CENTRO INTERNACIONAL DE ESTUDIOS SUPERIORES EN CIENCIAS AGRONOMICAS, SUPAGROInventors: Oscar Gerardo Acosta Montoya, Ana Mercedes Perez Carvajal, Manuel Dornier, Fabrice Vaillant
