Biosynthetic profiles of neutrophil serine proteases in a human bone marrow-derived cellular myeloid differentiation model

Background and Objectives. Human leukocyte elastase, proteinase 3 and cathepsin G are neutrophil granule proteins belonging to the hematopoietic serine protease superfamily. In addition to their established roles in inflammation, they have recently been implicated as regulators of granulopoiesis and mediators of apoptosis. We set out to characterize the individual biosynthetic profiles of these pr

Cyanobacterial chemical warfare alters zooplankton commuinty composition

1) Toxic algal blooms widely affect our use of water resources both with respect to drinking water and recreation. However, it is not only humans, but also organisms living in freshwater and marine ecosystems, that may be affected by algal toxins. 2) In order to assess if cyanobacterial toxins affect the composition of natural zooplankton communities, we quantified the temporal fluctuations in mi

Endothelin receptor changes during inflammation in the lung.

Popular Abstract in Swedish Svensk sammanfattning (Swedish Summary) Inflammatoriska sjukdomar i luftvägarna tillhör ett av de vanligaste skälen till ohälsa. Astma, både allergisk och icke allergisk, kan debutera redan under de första levnadsåren och kan på lång sikt ge kroniskt nedsatt lungfunktion. Bland medelålder's och äldre personer är kronisk obstruktiv lungsjukdom (KOL) vanligast, oftast etEndothelin-1 (ET-1) is an extremely potent smooth muscle spasmogen well known from the vascular system but also active within the airways. The importance of its proinflammatory and co-mitogenic properties has become increasingly evident, the endothelin system also having been shown to mimic the signal features of asthma, COPD and other pulmonary diseases. The present thesis concerns the role of th

The aim of this thesis is to investigate the functions of the word "tot" 'whole; each; all' in old and modern Romanian, by studying the syntax, morphology and semantics of this word as part of or in combination with a noun phrase (NP). An attempt is made to find out the status of "tot" in a classification of numerals, articles and adjectives. The present work consists of four separate studies (i.

Man hittar sin nisch. Om män i socionomyrket - karriär, minoritet och maskulinitet

This dissertation is about men as a minority in a female profession, that of university- trained social worker. The aim is to illuminate the relationship between work and gender on the basis of career, minority, and masculinity in the profession of social work. By means of questionnaires sent to all the men who trained as social workers in Lund 1980–1985 (the 1980s generation) and 1993–2003 (the 1

Fulminating clostridial septicemia in children treated for lymphoproliferative disorders

Overwhelming Clostridium septicum infection in 2 children, 1 and 4 yr old, with acute lymphoblastic leukemia and B-cell non-Hodgkin malignant lymphoma, respectively, as well as fatal C. perfringens infection in a 3-yr-old child with histiocytosis-X are reported. A neutropenic patient with fever, abdominal symptoms and hypotension--but otherwise being well--must be suspected of having clostridial d

Supported liquid membrane extraction for identification of phenolic compounds in the nutrient solution of closed hydroponic growing systems for tomato

The objective of the present study was to adapt and develop suitable methods to study the occurrence metabolites in the nutrient solution of hydroponically grown tomato. The organic-chemical nature of the nutrient solution from tomato grown in closed hydroponic systems was studied by supported liquid membrane technique (SLM) and analyzed by high-performance liquid chromatography (HPLC). Further, w

Optimisation of steam pretreatment of SO2-impregnated mixed softwoods for ethanol production

Pretreatment of mixed softwoods with SO2 impregnation and steam for production of ethanol has been investigated. The optimal conditions, both for sugar yield and ethanol yield, to assess the effect of inhibitors formed in the pretreatment, have been determined. The parameters investigated were: SO2 concentration (1-6% (w/w) dry matter), temperature (190-230 degrees C) and residence time (2-15 min)

Lean NOx reduction in real diesel exhaust with copper and platinum titania based monolithic catalysts

A study on the catalytic behaviour of a copper and a platinum titania based monolithic catalyst in the reduction of nitrogen oxides with hydrocarbons in real diesel conditions was carried out. A Volvo TD 7.31 engine was used as gas source, and diesel fuel was the reductant. In these conditions, both catalysts were active in the reduction reaction. The influence of various operating parameters on t
