A model for steam gasification of biomass was developed by applying thermodynamic equilibrium calculations. With this model, the simulation of a decentralized combined heat and power station based on a dual fluidized-bed steam gasifier was carried out. Fuel composition (ultimate analysis and moisture content) and the operating parameters, temperature and(More)
Following a severe septic abdominal infection induced by sublethal cecal ligation and puncture (CLP) in mice, a phase of depressed immune reactivity occurred two days after CLP characterized by a reduced capacity to produce TNF. To determine whether this reduced TNF production causes immunoparalysis as determined by increased susceptibility to bacterial(More)
Using tumor necrosis factor receptor type 2 (TNFR2)-deficient mice and generating bone marrow chimeras which express TNFR2 on either hematopoietic or nonhematopoietic cells, we demonstrated the requirement for TNFR2 expression on tissue cells to induce lethal cerebral malaria. Thus, TNFR2 on the brain vasculature mediates tumor necrosis factor-induced(More)
Twenty-one patients, aged 50 to 75 yr, received orthopedic surgery for lumbar spinal stenosis during the period of 1975-79. Presentation and management are discussed and surgical results evaluated clinically. Twenty of these patients had subjective pain relief as well as functional improvement, indicating that decompressive laminectomy offers an improved(More)
The occurrence of peritoneal adhesions in surgical patients is positively correlated with tumor necrosis factor (TNF) levels. In a model of septic peritonitis-cecal ligation and puncture-TNF neutralization prevented formation of peritoneal adhesions and increased mortality, most likely because localization of the septic focus was prevented. To discriminate(More)
A marked elevation of sialyltransferase activity (STA) was observed in a solid tumor of plasma cells, which had been removed from a patient with multiple myeloma (MM), as compared to normal lymphatic tissues. STA was also determined in mononuclear bone marrow cells of 10 patients with MM and found to be 12 times higher than that of bone marrow mononuclear(More)
907 patients were operated on for fracture of the proximal femur in 1986-1987 and were then followed for an average of 7 months. There was a relatively high rate of complications in those over the age of 71, in whom mortality reached 15.5%, while the overall mortality was 6.8%. There was also a high rate of complications in those operated 3 or more days(More)
The continuous intraventricular administration of small daily doses of morphine by means of an implantable pump is an effective method of obtaining considerable pain reduction for patients suffering from otherwise untractable carcinoma pain. We consider this method of treatment to be an excellent alternative to the epidural and intrathecal application.(More)
Snapping or triggering of fingers is a common complaint, the most frequent cause being tenosynovitis of the flexor tendon sheath. Injury of the flexor tendon as a precursor of triggering is infrequent. Foreign body granuloma of the tendon sheath as an antecedent factor has not been yet recorded. We report a case of stenosing tenosynovitis of the flexor(More)
