The fatty acid composition of microsamples from 10 AGA term, 8 SGA term, 7 AGA preterm and 4 SGA preterm, 2-4 day old infants and their mothers were analyzed. In AGA preterm newborns the mean percent of palmitic and stearic acid was lower and the mean percent of linoleic acid was higher than in AGA term infants indicating that there is an increase in fatty(More)
Experimental and clinical studies indicate that low molecular weight heparins (LMWH) may inhibit cancer and/or metastasis. The purpose of this study was to investigate whether it is possible to design non-anti-coagulant, anti-metastatic compounds based on heparin. The LMWH Tinzaparin and a series of non-anti-coagulant (NAC) heparin derivatives, varying in(More)
The fatty acid composition of the major plasma lipids and blood lymphocyte phospholipids was studied in four patients before and after 1 month of parenteral nutrition including 2 to 3 g/kg/day of Intralipid fat and in four matched controls before and after 1 month of breast-feeding. After treatment with Intralipid the concentration of polyunsaturated fatty(More)
The contamination of the widely used lifesaving anticoagulant drug heparin in 2007 has drawn renewed attention to the challenges that are associated with the characterization, quality control and standardization of complex biological medicines from natural sources. Heparin is a linear, highly sulfated polysaccharide consisting of alternating glucosamine and(More)
Since low-molecular-weight heparins (LMWHs) are eliminated preferentially via the kidneys, the potential for accumulation of these agents (and an increased risk of bleeding) is of particular concern in populations with a high prevalence of renal impairment, such as the elderly and patients with cancer. The risk of clinically relevant accumulation of(More)
A method for the determination of angiotensin-converting enzyme in serum (S-ACE; EC 3.4.15.1.) with use of 3-(2-furylacryloyl)-L-phenylalanyl-glycyl-glycine (FAPGG) as substrate has been adapted for the Cobas Bio microcentrifugal analyser. The method allows 24 determinations per hour in a sample volume of 28 microliters with a within run precision of less(More)
Protamine sulphate is an effective inhibitor of heparin and is used clinically to neutralise both low molecular weight heparins (LMWH) and unfractionated heparin (UFH). However, protamine sulphate does not fully counter the anti-Xa effect of LMWH, even in excess (>40 μg to 1 IU/ml). To investigate the molecular basis for this observation, the residual(More)
