Finegoldia magna is a member of the normal human bacterial flora on the skin and other non-sterile body surfaces, but this anaerobic coccus is also an important opportunistic pathogen. SufA was the first F. magna proteinase to be isolated and characterized. Many bacterial pathogens interfere with different steps of blood coagulation, and here we describe how purified SufA efficiently and specifica

Cholesterol-lowering effects of oats have been demonstrated in both animals and human subjects. However, the crucial properties of oat-containing diets that determine their health effects need to be further investigated to optimise their use. A mouse model would be a valuable tool, but few such studies have been published to date. We investigated the effects of oat bran on plasma cholesterol and l

Tumors can induce the generation and accumulation of immunosuppressive cells such as myeloid-derived suppressor cells (MDSCs) in a tumor microenvironment, contributing to tumor escape from immunological attack. Although dendritic cell-based cancer vaccines can initiate antitumor immune responses, tumor-educated dendritic cells (TEDCs) involved in the tolerance induction have attracted much attenti

OBJECTIVES: The methyltransferase genotype and pregnancy both influence the arsenic metabolism phenotype, but it is unknown whether these factors interact, explaining the drastic changes in the efficiency of arsenic metabolism observed among pregnant women. The aim of this study was to evaluate the relative contribution of the methyltransferase genotype and pregnancy to the arsenic metabolism phe

BACKGROUND: Phosphoinositide (PI) 3-kinase and its second messenger products, phosphatidylinositol 3,4,5-trisphosphate (PtdIns(3,4,5)P(3)) and phosphatidylinositol 3,4-bisphosphate (PtdIns(3,4)P(2)), play important roles in signalling processes crucial for cell movement, differentiation and survival. Previously, we isolated a 32kDa PtdIns(3,4,5)P(3)-binding protein from porcine leukocytes. This pr

BACKGROUND: Recently we have shown that serotonin receptors may be involved in prostate cancer development. In ovarian carcinogenesis, oestrogen may play a role. As oestrogen seems to mediate at least some of its biological effects through serotonin, we decided to evaluate if serotonin receptors are expressed in ovary and in ovarian tumours and if the expression is correlated to ovarian tumour dev

Small intestinal lamina propria (SI-LP) CD103(+) dendritic cells (DCs) are imprinted with an ability to metabolize vitamin A (retinol), a property underlying their enhanced capacity to induce the gut-homing receptors CC chemokine receptor-9 and α4β7 on responding T cells. In this study, we demonstrate that imprinting of CD103(+) DCs is itself critically dependent on vitamin A and occurs locally wi

AIM: To assess the prognostic value of repetitive serum samples of neuron specific enolase (NSE) and S-100B in cardiac arrest patients treated with hypothermia. METHODS: In a three-centre study, comatose patients after cardiac arrest were treated with hypothermia at 33 degrees C for 24h, regardless of cause or the initial rhythm. Serum samples were collected at 2, 24, 48 and 72h after the arrest a

We report the purification of betaglycan, a low-abundance membrane proteoglycan with high affinity for transforming growth factor-beta (TGF-beta). Betaglycan solubilized from rat embryo membrane preparations was purified to near-homogeneity by sequential chromatography through DEAE-Trisacryl, wheat germ lectin-Sepharose, and TGF-beta 1-agarose. Purified betaglycan has properties similar to betagly

DESIGN: Cross-sectional study. SETTING: University-based rehabilitation center. PARTICIPANTS: Tai Chi practitioners (n=24; age+/-SD, 68.5+/-6.6 y) and control subjects (n=20; age, 71.3+/-6.7 y) were recruited. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Measures included the following: (1) subjects' intentional weight shifting to 8 different spatial positions within their base of support

Glucose metabolism is subjected to diurnal variation, which might be mediated by alterations in the transcription pattern of clock genes and regulated by hormonal factors, as has been demonstrated for insulin. However, whether also glucagon is involved in the diurnal variation of glucose homeostasis is not known. We therefore examined glucagon secretion after meal ingestion (meal tolerance test) a

The equation , whereH is Heaviside's step function, appears for example in continuous sedimentation of solid particles in a liquid, in two-phase flow, in traffic-flow analysis and in ion etching. The discontinuity of the flux function atx=0 causes a discontinuity of a solution, which is not uniquely determined by the initial data. The equation can be written as a triangular 2×2 non-strictly hyperb

The membrane lipid glucosylceramide (GlcCer) is continuously formed and degraded. Cells express two GlcCer-degrading β-glucosidases, GBA and GBA2, located in and outside the lysosome, respectively. Here we demonstrate that through transglucosylation both GBA and GBA2 are able to catalyze in vitro the transfer of glucosyl-moieties from GlcCer to cholesterol, and vice versa. Furthermore, the natural

OBJECTIVE: The tyrosine kinase receptor Axl is expressed in the vasculature and Gas6 is the ligand. The extracellular part of Axl (sAxl) can be found in circulation. The aim of this study was to determine plasma concentrations of Gas6 and sAxl in patients with abdominal aortic aneurysms (AAA) and to evaluate if Gas6 and sAxl can be used as biomarkers. DESIGN AND METHODS: Immunoassays for sAxl and

The Medtronic Resting Heart System (RHS) is a heparin-coated, closed perfusion circuit. Clinical results indicate less haemodilution and reduced complement activation, when compared with a traditional circuit leading to fewer postoperative blood transfusions. We evaluated the potential clinical benefits, including reduced transfusion requirements, when using the RHS compared with conventional card

A major phytoplankton change occurred during the late 1930s and early 1940s in Koljö Fjord, a sill fjord on the Swedish west coast. Dinoflagellate cyst concentrations increased tenfold over a short period of time, from hundreds of cysts per gram sediment to thousands; and the species composition of both dinoflagellate cysts and diatoms changed markedly. These changes took place during a period of

Abstract in UndeterminedThe hitherto most successful theory explaining why similar industrialized market economies have developed such varying systems for social protection is the Power Resource Theory (PRT), according to which the generosity of the welfare state is a function of working class mobilization. In this paper, we argue that there is an under-theorized link in the micro-foundations for

Background: Nurse assistants working in residential care facilities need support to ensure that they provide high-quality care for the residents and support for relatives, from admission to bereavement. Aim. The aim was to describe the nurse assistants' experience of how an intervention with a palliative care approach, had influenced them in their work in residential care for older people. Parti
