Investigation of Burkholderia cepacia nosocomial outbreak with high fatality in patients suffering from diseases other than cystic fibrosis

Over a 1-y period, 26 inpatients at the Jordan University Hospital in Amman were detected with bacteraemia (23 cases) or respiratory tract colonized with B. cepacia (3 cases). A combination of genetic identification and molecular typing has proved that all cases were caused by a single epidemic strain of B. cepacia genomovar IIIa. Nosocomial infections could be documented in 21/26 (81%) patients,

Resonant photoemission at the 2p edge in compounds containing Mn with different valences

We have investigated the Raman-Auger crossover of the Mn 2p non-radiative decays in bulk MnO. For the highest kinetic energy transition in the Mn 2p3p3p decay, Raman behaviour is observed up to approximate to 3.4 eV above the resonance energy (maximum of the L-3 absorption). In the case of the 2p3p3d and 2p3d3d transitions a similar situation occurs up to approximate to 5 eV above the resonance en

False positive results in class-specific rheumatoid factor (RF) assays due to interaction between RF and Fc fragments of anti-immunoglobulin indicator reagents

A recently developed, simple immunological method, diffusion-in-gel ELISA, has been adapted for class-specific determination of rheumatoid factor (RF). Evidence was obtained of an analytical error due to interaction between RF and antigenic determinants on the Fc part of the indicator immunoglobulin (Ig) molecules used. This was eliminated by replacing the usual indicator reagent, complete Ig mole

Prediction of death in patients with primary intracerebral hemorrhage: a prospective study of a defined population.

OBJECT: Predictors of early (30-day) and long-term (1-year) mortality rates after primary intracerebral hemorrhage (ICH) were studied in a large population in southern Sweden. METHODS: All cases of primary ICH, verified using computerized tomography (CT) scanning or autopsy study, were prospectively registered at the 12 hospitals covering a defined population of 1.14 million during the calendar ye

Retroelement distributions in the human genome: variations associated with age and proximity to genes.

Remnants of more than 3 million transposable elements, primarily retroelements, comprise nearly half of the human genome and have generated much speculation concerning their evolutionary significance. We have exploited the draft human genome sequence to examine the distributions of retroelements on a genome-wide scale. Here we show that genomic densities of 10 major classes of human retroelements

L-Arabinose metabolism in Candida arabinofermentans PYCC 5603(T) and Pichia guilliermondii PYCC 3012: influence of sugar and oxygen on product formation

L-Arabinose utilization by the yeasts Candida arabinofermentans PYCC 5603(T) and Pichia guilliermondii PYCC 3012 was investigated in aerobic batch cultures and compared, under similar conditions, to D-glucose and D-xylose metabolism. At high aeration levels, only biomass was formed from all the three sugars. When oxygen became limited, ethanol was produced from D-glucose, demonstrating a fermentat

Fairness in Communication and Computer Network Design

In communication networks, fair sharing of resources is an important issue for one main reason. The growth of network capacity is in general not matching the rapid growth of traffic. Consequently, the resources consumed by each user have to be limited. This implies that users cannot always be assigned the end-to-end bandwidth they ask for. Instead, the limited network resources should be distribut

Shifts between clear and turbid states in a shallow lake: multi-causal stress from climate, nutrients and biotic interactions

We used long-term monitoring data to assess causes behind a recent shift front a clear to a turbid water state in Lake Takern, Sweden. The lake has a previous record of shifts between clear-water and turbid states. but the causes behind these shifts are not well known. During the recent shift, which occurred in 1995-1997, Submerged vegetation Subsequently declined after a 30-year period of clear-w

Recirculation of process water in the production of ethanol from softwood

In the production of ethanol from lignocellulosics, large quantities of water are needed in various process steps. In industrial processes, recycling of process streams is necessary to minimise fresh water requirements and decrease the amount of wastewater produced. This leads to increases in various substances, both volatile and non-volatile which inhibit fermentation. In the present Study ethano

Wheelchair Passengers and Local Public Transport Vehicles: Perceptions of Safety and Comfort

Popular Abstract in Swedish Målet med kollektivtrafik är bl a att anordna transportförsörjning för alla samhällsgrupper på ett samhällsekonomiskt effektivt vis. En grupp medborgare är rullstolsburna resenärer, vars speciella förutsättningar ställer särskilda krav på transportsystemets utformning. För att utröna dessa speciella förutsättningar på ett ansvarsfullt sätt, är det viktigt att man anläggEliciting wheelchair-seated passengers’ perspective of safety and comfort is both useful and mandatory, particularly for researchers, clinicians, transit authorities, and for operators during purchase and use of vehicle technologies in existing and planned future transport systems. Therefore, the overarching objective of this thesis was to delineate the question of safety and comfort as perceived

Development of a carbon nanotube paste electrode osmium polymer-mediated biosensor for determination of glucose in alcoholic beverages

This paper describes a new amperometric biosensor for glucose monitoring. The biosensor is based on the activity of glucose dehydrogenase (GDH) and diaphorase (DI) co-immobilized with NAD(+) into a carbon nanotube paste (CNTP) electrode modified with an osmium functionalized polymer. This mediator was demonstrated to shuttle the electron transfer between the immobilized diaphorase and the CNTP ele

Analysis of a Probing Control Strategy

In this paper we analyse an extremum controller based on a pulse technique. The idea is to superimpose probing pulses to the control signal and use the size of the pulse response in the output for feedback. The probing control strategy has been used with success for the control of the substrate feeding in E. coli cultivations. The stability analysis is done here for systems of Hammerstein type wit

Assessment of Left Ventricular Dysfunction and Remodelling by Determination of Atrioventricular Plane Displacement and Simplified Echocardiography

Heart failure is a common disease characterised by poor prognosis and frequent hospitalisations, constituting a major economic burden to society. Mortality and morbidity can be reduced by optimal treatment, requiring objective evaluation of cardiac function and anatomy. The development of symptomatic HF can be prevented by initiating adequate treatment in early stages when LVD is still asymptomati

Chronic suppurative otitis media in Tanzanian school children and its effects on hearing

OBJECTIVES: To compare different treatment regimens of chronic suppurative otitis media (CSOM) in school children, in regard to their consequence in hearing and discharge from the ear drum perforation. DESIGN: Randomised controlled trial. SETTING: Randomly selected primary schools within Dar es Salaam. SUBJECTS: Three hundred and twenty eight children between 5-17 years of age with CSOM in one or

5-ALA for photodynamic photorejuvenation - Optimization of treatment regime based on normal-skin fluorescence measurements

Background and Objectives: Photodynamic therapy using 20% 5 aminolevulinic acid (5-ALA) has recently been introduced as a new tool in optical skin rejuvenation. The primary objective of this study was to optimize incubation time, the topical delivery mechanism (vehicle) and the concentration of 5-ALA by detecting the dynamic changes of normal skin after 5-ALA application. The secondary objective w
