摘要:
In a combined process for the thermal and chemical treatment of lignocellulose-containing biomass and for the production of furfural, biomass is supplied to a cooker in batches, is heated in the cooker under the addition of cooking liquor, and cellulose or pre-treated biomass is withdrawn from the cooker in batches. In order to guarantee a high yield of furfural, cooking liquor is withdrawn from the cooker during the heating phase and is fed to a furfural production plant, and the cooking liquor at least largely freed from pentoses and furfural is returned to the cooker.

An in vitro method for the risk stratification of patients with stable arteriosclerosis, especially stable coronary artery disease, is disclosed wherein the concentration of procalcitonin is determined in the circulation of such patients using a highly sensitive PCT assay, and wherein within the range of PCT concentrations in the typical normal range of healthy individuals cutoff values are defined which distinguish groups of individual patients with stable arteriosclerosis in accordance with personal cardiac risk, and patients are allotted to one of said risk groups on the basis of their individual PCT concentrations.
摘要:
The present invention relates to a process for producing viscose pulp from lignocelluloses, such as hardwood, softwood or annual plants, in which process the lignocellulose is treated in a digester at first with saturated steam to prehydrolyze hemicelluloses and subsequently, without flashing, with hot black liquor (HSL) of a preceding sulfate pulp digestion as well as, if desired, under addition of fresh white liquor (WL) to neutralize the acidic reaction products formed, neutralization liquor (NL) thus being formed in the digester. Upon addition of the amount of alkali required for delignification in the form of fresh white liquor (WL), if desired, in combination with a displacement of neutralization liquor (NL) and temperature adjustment, digestion then will take place with or without temperature gradient. When reaching the desired degree of digestion, digestion is terminated by displacement of the hot black liquor (HSL) with cold alkaline washing filtrate (WF), at the same time the pulp is freed from still adhering lignin degradation products, and the thus obtained pulp is discharged from the digester at a temperature of below 100.degree. C.

The present invention relates to materials and procedures for evaluating patients suffering from cardiovascular conditions, particularly acute coronary syndromes. In particular, the presence, amount, or enzymatic activity of glutathione peroxidase-1 in a patient sample, alone or in combination with one or more other markers, provides diagnostic and/or prognostic information. While applicable to diseases and conditions in which inflammation is generally manifested, the methods and compositions described herein are particularly applicable to acute coronary syndromes, including conditions selected from the group consisting of unstable angina, non-ST-elevation non-Q wave myocardial infarction, ST-elevation non-Q wave MI, and transmural (Q-wave) MI.
