Perivascular cells (PC) were recently implied as regulators of metastasis and immune cell activity. Perivascular heterogeneity in clinical samples, and associations with other tumor features and outcome, remain largely unknown.Here we report a novel method for digital quantitative analyses of vessel characteristics and PC, which was applied to two collections of human metastatic colorectal cancer

We studied the relevance of adenomatous polyposis coli (APC)/beta-catenin signalling in the development of breast cancer by analysing the expression of beta-catenin in 54 primary breast tumours (34 ductal and 20 lobular). We showed that 13% of the tumours exhibited upregulated levels of beta-catenin in the cytosol suggesting that defects in APC/beta-catenin signalling components had lowered the ra

The metabolism in vivo in the rat of 125I-prothrombin-chylomicron complexes was compared to that of free 125I-prothrombin injected in saline or together with chyle chylomicrons. The group that obtained 125I-prothrombin-chylomicron complexes exhibited a faster initial decrease of plasma 125I-prothrombin, a higher radioactivity in the liver and more trichloroacetic acid soluble 125I in plasma than i

The effects of chylomicron-prothrombin complexes on platelet activation, including platelet aggregation, serotonin release, arachidonic acid release and increases of platelet cytosolic [Ca2+]i were examined. Furthermore the role of platelet factor Xa on the conversion of chylomicron bound prothrombin to thrombin was studied by using a synthetic inhibitor of factor Xa, TenStop.

This work is an experimental study covering minimum quantity lubrication (MQL) in sheet metal forming. Two different lubricants have been studied. Nanosized graphite platelets (GnP) has been tested as additives to the base oils in order to improve the lubricant performance. The experiments have been performed utilizing a laboratory tribotester based on strip drawing. Friction measurements have bee

Fiber reinforcement polymer (FRP) is a hard-to-treat material used in different areas of up-to-date machine building. It has excellent mechanical properties making the material unique in different engineering solutions such as aircraft, aerospace and boatbuilding. The optimization of holemaking operations in FRP is the main aim of the current investigation.

PurposeUganda is one of many African countries struggling to develop adequate healthcare, particularly in regard to local treatment and access to drugs. The purpose of this paper is to contribute to the understanding of how reducing supply-chain complexity can improve health in developing countries. Design/methodology/approachThis study and evaluation included 50 interviews and 27 site visits of t

Purpose – The purpose of this paper is to provide a review of the critical success factors (CSF) for lean and six sigma and an analysis of these CSF as compared to previously popular change methods. Design/methodology/approach – The paper uses a literature search and comparative analysis complemented with examples from previous case studies. Findings – With only slight variations, the critical suc

Adsorption of different lipases by EP-100 polypropylene powder from pure and pure lipase preparations was studied. Langmuir isotherms described the adsorption equilibria well both for protein and lipase activity adsorption. Adsorption isotherms for five different proteins all gave a similar saturation level of 220 mg protein per g carrier. Twelve commercial lipase preparations were tested for sele

The aim of this study was to thoroughly investigate the possibility of using enzyme catalyzed hydrolysis and alcoholysis of ester bonds in vitamin A and E esters to facilitate their determination in different food formulas. Two vitamin esters, retinyl palmitate and α-tocopheryl acetate were used as model compounds and two food formulas, milk powder and infant formula, were used as model matrices.

Six different lipases were screened for their ability of acidolysis between digalactosyldiacylglycerol (DGDG) and heptadecanoic acid in toluene. Lipases from Geotrichum candidum, Alcaligenes sp. and Penicillium camembertii did not catalyse the acidolysis reaction. Rhizopus arrhizus and Rhizomucor miehei (Lipozyme) catalysed the acidolysis but produced a mixture of DGMG, DGDG, acyl-DGMG and acyl-DG
