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

Naturally conceived twins with monochorionic placentation have the highest risk of fetal loss

Objective The aim of this study was to estimate the rate of fetal loss in dichorionic (DC) and monochorionic (MC) twin pregnancies stratified according to zygosity and method of conception. Methods In a prospective multicenter observational study women with a twin pregnancy bad an ultrasound scan before 14 + 6 weeks' gestation in order to determine chorionicity. The fetal loss rate, the perinatal,

Influence of methotrexate, TNF blockers and prednisolone on antibody responses to pneumococcal polysaccharide vaccine in patients with rheumatoid arthritis.

Objective. To compare antibody responses to 23-valent pneumococcal vaccine (Pneumovax (R)) in controls and patients with established rheumatoid arthritis (RA) treated with TNF blockers, methotrexate (MTX) or a combination of both. Methods. Patients with RA (n = 149) and healthy controls (n = 47) were vaccinated. Treatment with TNF blockers (etanercept or infliximab) and MTX was given to 50 patient

Det ljusa och det mörka rummet. Fotografiets limbo mellan död och frihet

Artikeln uppmärksammar hur fotografiet på grund av sin speciella relation till tiden och rummet är förankrat dels i en livsbevarande praxis och dels i en dödsbringande frysning av tid och rum. Artikeln prövar om den mystik som omgärdar den fotografiska praxisen kan spåras till en sådan "dubbel identitet".

Performance of distributed information systems

There is an increasing use of distributed computer systems to provide services in both traditional telephony as well as in the Internet. Two main technologies are Distributed Object Computing (DOC) and Web based services. One common DOC architecture investigated in this thesis is the Common Object Request Broker Architecture (CORBA), specified by the Object Management Group. CORBA applications con

Reduced leptin concentrations in subjects with type 2 diabetes mellitus in Sudan.

Differences have been observed in the relationship between leptin and metabolic perturbations in glucose homeostasis. Because no information is available from indigenous African populations with diabetes, the purpose of this study was to investigate the possible associations between leptin and different clinical and biochemical characteristics of a large group of subjects with type 2 diabetes mell

Purification of His(6)-organophosphate hydrolase using monolithic supermacroporous polyacrylamide cryogels developed for immobilized metal affinity chromatography

Organophosphate hydrolase containing hexahistidine tag at the N-terminus of recombinant protein (His(6)-OPH) and expressed in Escherichia coli cells was purified using supermacroporous polyacrylamide-based monolith columns with immobilized metal affinity matrices [Me2+-iminodiacetic acid (IDA)-polyacrylamide cryogel (PAA) and Me2+-N,N,N'-tris (carboxymethyl) ethylendiamine (TED)-PAA]. Enzyme prepa

E-bikes are getting increasingly more popular and often means a purchase of a brand new e-bike. But what if you could upgrade your already existing bike? Kits that convert standard bycycles are nothing new to the market. However, many suffer from being to technical, making it hard to source the correct parts for the users specific bicycle and specific needs. Other kits are much more user friendly

Att läsa för att förstå sin hotade omvärld: en aktionsforskningsstudie om klimatdidaktik och dialogbaserad strategiundervisning.

Denna uppsats syfte är att undersöka sätt att utveckla engagemang i och förståelse av klimatfrågan genom läsundervisning. Metoden jag har valt för att utreda det är aktionsforskning, genomförd på en gymnasieskola i södra Skåne. Där gjorde jag med sex elever en övning utifrån min valda sorts läsundervisning, lässtrategin dialogbaserad strategiundervisning, och en aktuell text om klimathotet. På så

Resultatmanipulering bland svenska företag före konkurs

Syfte: Syftet med denna studie är att undersöka om svenska företag resultatmanipulerar åren innan konkurs. Dessutom syftar denna studie till att undersöka om mängden resultatmanipulering åren innan konkurs korrelerar med hur kapitalintensiva företagen är och med företagens storlek. Metod: Studien har använt den modifierade Jones-modellen för att mäta mängden resultatmanipulering bland 738 svenskaPurpose: The purpose of this study is to examine if Swedish companies perform earnings management four years prior to filing for bankruptcy. This study also aims to examine whether the amount of earnings management before bankruptcy correlates with how capital intense the companies are and the size of the companies. Methodology: The modified Jones model has been used to measure the amount of earn
