Granted: 2009-03-10
Abstract: The invention disclosed is a process for determining the cytoprotective activity of plasma that prevents the destruction of endothelial cells and forestalls the development of a number of diseases such as atherosclerosis, preeclampsia, edema, nephrotic syndrome, and stroke. The present invention includes a method of diagnosing a patient's proclivity to develop a disease having a correlation to a reduction in the concentration of pI 5.6 albumin in the plasma by determining a value indicative of the concentration of the pI. 5.6 albumin that is not bound to VLDL  ("non-VLDL-bound pI 5.6 albumin") in the patient's blood serum. The preferred embodiment of the process utilizes in vitro methods to obtain an indicator of the non-VLDL-bound pI. 5.6 albumin instead of directly measuring the concentration of the non-VLDL-bound pI 5.6 albumin.

Abstract: The present invention pertains to a process for sulphiding a catalyst composition comprising at least one hydrogena-tion metal component of Group VI and/or Group VIII of the Periodic Table, and an S-containing organic additive wherein the catalyst composition is first contacted with an organic liquid, followed by the catalyst being contacted with hydrogen and a sulphur-contain-ing compound in the gaseous phase. Catalysts sulphided by the process according to the invention show a higher activity than the same catalysts which have not been sulphided. It is preferred to carry out the process according to the invention ex situ, where it solves the problem of difficult start-up and the formation of undesirable side products in the hydrotreating unit. The organic liquid may be a hydrocarbon with a boiling range of 150-500 °C, preferably white oil, gasoline, diesel, gas oil, or mineral lube oil. The S-containing organic additive preferably is a mercapto-compound, more preferably a mercaptocarboxylic acid represented by the general formula: HS-RI-COOR, wherein R1 stands for a divalent hydrocarbon group with 1-10 carbon atoms and R stands for a hydrogen atom, an alkali metal, an alkaline earth metal, ammonium, or a linear or branched alkyl group having 1 to 10 carbon atoms.

When expressed, the sequence encoding the xylose isomerase confers to the host cell the ability to convert xylose to xylulose which may be further metabolised by the host cell. Thus, the host cell is capable of growth on xylose as carbon source. The host cell preferably is a eukaryotic microorganism such as a yeast or a filamentous fungus. The invention further relates to processes for the production of fermentation products such as ethanol, in which a host cell of the invention uses xylose for growth and for the production of the fermentation product. The invention further relates to nucleic acid sequences encoding eukaryotic xylose isomerases and xylulose kinases as obtainable from anaerobic fungi.
