Metastatic disease is responsible for most cancer deaths, and hematogenous spread through circulating tumor cells (CTC) is a prerequisite for tumor dissemination. CTCs may undergo epithelial–mesenchymal transition where many epithelial cell characteristics are lost. Therefore, CTC isolation systems relying on epithelial cell markers are at risk of losing important subpopulations of cells. Here, a
Lipase-(Lipozyme TL IM) catalyzed interesterification of triacylglycerols was studied at water activities (a(w)) from 0.22 to 0.8. The substrates trilaurin (LLL) and 1,3-palmitin-2-olein (POP) were used in equimolar amounts to facilitate separate measurements of the interesterification in the sn-1,3 positions and changes in the fatty acid (FA) composition in the sn-2 position. The reaction at a(w)
The anticoagulant vitamin K-dependent protein S (PS) circulates in plasma in two forms, 30% free and 70% being bound to the complement regulatory protein C4b-binding protein (C4BP). The major C4BP isoform consists of 7 alpha-chains and 1 beta-chain (C4BP beta(+)), the chains being linked by disulfide bridges. PS binds to the beta-chain with high affinity. In plasma, PS is in molar excess over C4BP
Background: Some patients with allergic asthma treated with anti-IgE (Xolair (R)) do not become symptom free. Better criteria for response assessment than allergy skin tests or IgE determination are needed. The impact of the size of the disease relevant allergen-specific IgE antibody fraction, i.e. the percentage of IgE antibody of total IgE, was evaluated in cat allergic patients treated with the
Thin, free films based on Kollicoat SR:Eudragit NE blends were prepared by casting or spraying aqueous dispersions of these polymers, and were thoroughly characterized with respect to their water uptake behavior, water permeability, dry mass loss kinetics, mechanical properties and drug release patterns. A mechanistic mathematical model based on Fick's law of diffusion was used to quantify the exp
Objective: To test the hypothesis that the growth hormone (GH) receptor (GHR) d3/fl polymorphism influences anthropometry and body composition in the general population. Design and Setting: The Swedish Obese Subjects (SOS) reference study is a cross-sectional population-based study, randomly selected from a population registry. A sub-group of the population-based Malmö Diet and Cancer Study (MDC-C
Various samples of the solid solution Gd2NixCu2-xMg were synthesized from the elements in sealed tantalum ampoules in an induction furnace. All members crystallize with the tetragonal Mo2FeB2 type structure, space group P4/mbm, and they were characterized on the basis of Guinier powder patterns and energy dispersive X-rays analyses. The lattice parameters decrease with increasing nickel content in
Background Hyperandrogenicity in women is a risk factor for cardiovascular disease and noninsulin-dependent diabetes mellitus (NIDDM). Estradiol alone decreases hyperandrogenicity and have beneficial effects on glucose metabolism and plasma lipids in postmenopausal women with type 2 diabetes. Objectives To analyse effects on glucose homeostasis and plasma lipids by 2 mg estradiol and 1 mg noreth
Popular Abstract in Swedish Kroniskt Obstruktiv Lungsjukdom (KOL) är idag världens fjärde vanligaste dödsorsak vars dödlighetsfrekvens ökar. KOL är en lungsjukdom som nästan alltid beror på rökning och i hela världen är cirka 600 miljoner människor drabbade av sjukdomen. Detta gör KOL till världens vanligaste kroniska sjukdom. I Sverige beräknas sjukvårdskostnaderna för KOL att uppgå till ca 9,1 mProteomic analysis of bronchoalveolar lavage (BAL) fluid from smokers at risk of developing chronic obstructive pulmonary disease (COPD) and never smokers is described. COPD is currently the world's fourth leading cause of death and its prevalence is increasing. The leading cause of COPD is smoking and an estimated 600 million people in the world suffer from COPD which makes it the world's most co
Intracellular lipolysis is a major pathway of lipid metabolism that has roles, not only in the provision of free fatty acids as energy substrate, but also in intracellular signal transduction. The latter is likely to be particularly important in the regulation of insulin secretion from islet beta-cells. The mechanisms by which lipolysis is regulated in different tissues is, therefore, of considera
Liver plays a key role in the metabolism of plasma apolipoproteins, endogenous lipids and lipoproteins. Hepatocellular carcinoma (HCC) is one of the most common fatal malignant tumors in China and in other Southeast Asian countries. This has been attributed to the high incidence of hepatitis B infection. Hepatitis B proteins, such as the hepatitis B X protein (HBx) that is large hepatitis B surfac
Glucocorticoids play a role in the origin of the features of the metabolic diseases. Alpha-ketoglutarate (AKG) is defined as glutamine homologue and derivative, conditionally an essential amino acid. In the liver, glutamine serves as a precursor for ureagenesis, gluconeogenesis and acute phase protein synthesis The aim of the study was to determine the effect of AKG administered to piglets prenata
In this paper we study an optimization problem relevant for wireless networks. In such networks links are subject to capacity disruptions caused by changing weather/channel condition that force to adapt the modulation and coding schemes to the observed condition. To cope with this issue in network optimization, we need to consider a so called link availability set A and a routing strategy that can
What happens to law when social institutions which ground its normativity become unstable and transitory? How can regulation make sense when fleetingness and fluidity become the enduring property of social structures? The social consequences of globalisation and the rise of the network society have heightened and expanded human agency’s powers of reflexivity vis-à-vis social structures. They have
OBJECTIVE: 5-azacytidine (azacytidine), a DNA hypomethylating agent, was recently approved as the first therapeutic agent for the treatment of myelodysplastic syndromes. The present subcutaneous dosing schedule, 75 mg/m(2) for 7/28 days, is based on early clinical studies and may constitute a practical problem for patients. The present in vitro study aimed at evaluating the pharmacodynamics of aza
The calcineurin/nuclear factor of activated T cells ( NFAT) signaling pathway has been found to play a role in regulating growth and differentiation in several cell types. However, the functional significance of NFAT in the vasculature is largely unclear. Here we show that NFATc1, NFATc3, and NFATc4 are expressed in human myometrial arteries. Confocal immunofluorescence and Western blot analysis r
The concentration-response relation for Ca2+ (0.2-5.0 mM) of high-K+ contractures (40 mM) in the rat portal vein during respiratory inhibition by 0.2 mM cyanide was investigated. A reduction of force in the presence of cyanide to about 30% of control was associated with a leftward shift of the normalized concentration-response relation. When force at the plateau of high-K+ contractures (at about 2
To estimate the incidence and extension of visceral organ infarction, and to evaluate potential causes, in patients with autopsy-verified nonocclusive mesenteric ischaemia (NOMI) and transmural intestinal infarction. In Malmo, Sweden, the autopsy rate between 1970 and 1982 was 87%, creating possibilities for a population-based study. Amongst 23 446 clinical autopsies, 997 cases were coded for inte
An integrated process for purifying a 6.1 kilo base pair (kbp) plasmid from a clarified Escherichia coli cell lysate based on an ultra/diafiltration step combined with polymer/polymer aqueous two-phase system and a new type of chromatography is described. The process starts with a volume reduction (ultrafiltration) and buffer exchange (diafiltration) of the clarified lysate using a hollow fibre me
