    摘要: The present invention provides a method for production of functional proteins including hormones by renal cells in a three dimensional co-culture process responsive to shear stress using a rotating wall vessel. Natural mixture of renal cells expresses the enzyme 1-a-hydroxylase which can be used to generate the active form of vitamin D: 1,25-diOH vitamin D3. The fibroblast cultures and co-culture of renal cortical cells express the gene for erythropoietin and secrete erythropoietin into the culture supernatant. Other shear stress response genes are also modulated by shear stress, such as toxin receptors megalin and cubulin (gp280). Also provided is a method of treating in-need individual with the functional proteins produced in a three dimensional co-culture process responsive to shear stress using a rotating wall vessel.

    摘要: A polymer composition comprises (a) a stereospecific, preferably fermentation derived, polyester of molecular weight Mw over 100000 consisting of repeating units of formula --O--C.sub.m H.sub.n --CO-- in which n=2m and units with m=3 and m=4 with respectively a C.sub.1 and C.sub.2 side group on the carbon atom next to oxygen in the polymer chain are copolymerised together, m being 3 in 70-95 mol percent of such units; and (b) at least one alkyl phenol in which the alkyl group preferably contains at least one tertiary carbon atom adjacent to or within 4 carbon atoms of the phenol nucleus. The alkyl phenol may be hindered and may contain a C.sub.1-6 alkoxy group para to the phenolic hydroxy group. Suitable alkyl phenols include 2-tert-butyl-4-hydroxy-anisole and alpha- or delta- tocopherol and others usable as antioxidants in foods, oils and polymer systems. The polyester and alkyl phenol and relative proportions thereof are preferably chosen to provide inhibition of crystallisation of the polyester corresponding to an Avrami `k` parameter less than 0.03.

    摘要: A hydroxycarboxylic acid copolyester of R-stereospecific configuration contains a majority of first repeating units capable of forming a highly crystalline high-melting homopolyester and a minority of second repeating units capable when randomly copolycondensed with said first repeating units of lowering the melting point of said homopolyester and is characterised by one or more of: higher crystalline melting point, shorter crystallising time, higher notched impact strength at age 1 month, as compared with corresponding random polyester, and said majority repeating units in the polyester chain being present in blocks longer than correspond to their over-all molar proportionality. The copolyester may be made by fermentation, controlling the distribution of repeating units by reference to the pattern of feeding substrates corresponding to the respective repeating units.
