On-chip enzyme reactors are often used in medical/pharmaceutical analysis due to their inherent advantages, such as high sample throughput, low reagent consumption, stability, reproducibility and low cost. The present work describes a different application of such microreactors, namely, elimination of interfering ascorbate signals in glutamate monitoring using ascorbate oxidase modified silicon ch
Airborne dust samples from damp (n = 9) and control (n = 9) residences were analyzed for microorganisms (molds and bacteria), bacterial markers (3-hydroxy fatty acids and muramic acid), and adsorbed volatile organic compounds (VOCs). The number of mold species was greater in the damp residences than in the controls (23 vs.18) and nine mold species were found only in damp residences. The levels of
Protein C (PC), a 62 kDa multi-modular zymogen, is activated to an anticoagulant serine protease (activated PC or APC) by thrombin bound to thrombomodulin on the surface of endothelial cells. PC/APC interacts with many proteins and the characterisation of these interactions is not trivial. However, molecular modelling methods help to study these complex biological processes and provide basis for r
In 1986, Keil provided an O(n(2)) time algorithm for the problem of covering monotone orthogonal polygons with the minimum number of r-star-shaped orthogonal polygons. This was later improved to O(n) time and space by Gewali et al. in [L. Gewali, M. Keil, S.C. Ntafos, On covering orthogonal polygons with star-shaped polygons, Information Sciences 65 (1992) 45-63]. In this paper we simplify the lat
Using the Fourier Transform Spectrometer at Lund Observatory, intensity calibrated spectra of singly ionized zirconium have been recorded and analyzed. Oscillator strengths for 263 Zr II spectral lines in the region 2500-5400 angstrom have been derived by combining new experimental branching fractions with previously measured radiative lifetimes. The transitions combine 34 odd parity levels with 2

Objective: The aim in this study was to assess the association between individual plasma carotenoid levels (alpha-carotene, beta-carotene, lycopene, beta-cryptoxanthin, lutein, zeaxanthin) and fruit and vegetable intakes recorded by a calibrated food questionnaire (FQ) and 24- h dietary recall records (24HDR) in nine different European countries with diverse populations and widely varying intakes
The thesis deals with the determination of the post peak behaviour of concrete in pure tension, and combined tension (compression) and shear. A test arrangement has been developed in order to determine the post peak behaviour of concrete expressed as stress - displacement curves. The theoretical basis of the thesis is in accordance with the "Fictitious Crack Model" which is a model based on the s
I denna artikel diskuteras betydelsen av kroppen som en uppmärksam och aktiv aktör i rituell praktik, förankrad i en specifik social och historisk kontext, de kanadensiska mi’kmaqindianernas livsvärld. Mi’kmaqs möjlighet att arbeta om den kulturella kropp det dominerande samhället har implementerat i dem, öppnar nya vägar att göra sig av med destruktiva mönster som de medvetet eller omedvetet har
The effect of thermal ionization on the growth of soot particles has been analyzed by detailed kinetic modeling of a low-pressure premixed acetylene flame. The detailed kinetic model considers the oxidation of fuel, the formation and growth of polycyclic aromatic hydrocarbons, and particle inception, coagulation, as well as mass growth via surface reactions. A numerical method has been developed,
Objective. Ileal pouch anal anastomosis ( IPAA) is the preferred method for restorative surgery in patients with ulcerative colitis who have to undergo proctocolectomy. The most common complication is pouchitis and several studies have pointed to the microbiota of the pouch as being a risk factor. The aim of this study was to follow the development of the bacterial microbiota in pouches during the
This article examines the use of demonizing rhetoric by the Chinese Communist Party during the first decades of the People’s Republic after 1949. It chronicles the rise, flourishing, and ultimate post-Mao demise of a political discourse predicated on an ‘essential’ distinction between people and non-people. With the help of illustrations lifted from public and until recently classified sources, it
Since 1999 the Swedish National Board of Health and Welfare (Socialstyrelsen) has been piloting a project entitled “Children’s Needs in Focus” (BBIC). The aim of this development project is to develop a uniform system of assessing, planning and reviewing in social work with children. It is inspired by the Integrated Children’s System (ICS) in Great Britain and the Swedish Dartingtonproject. The Br
BACKGROUND: A standardised technique using a suction-induced mini-erosion that allows serial sampling of dermal interstitial fluid (IF) for 5 to 6 days has been described. In the present study, we studied permeability changes as a function of time. METHODS: We examined IF concentrations of total protein concentration and the concentration of insulin (6.6 kDa), prealbumin (55 kDa), albumin (66 kDa)
Popular Abstract in Swedish Cirkulationen i de minsta kärlen, de s.k. mikrovaskulära utbyteskärlen är viktig för vävnadens syre- och näringstillförsel. Mikrocirkulationen utgörs av de minsta artärerna, kapillärerna, och de minsta venerna. I kapillärerna och i de minsta venerna sker utbytet av näring, syre, samt koldi-oxid och andra metabola restprodukter. För fettlösliga ämnen som koldioxid och syThis thesis presents some effects of Rho kinase, prostacyclin (PGI2) and nitric oxide (NO) in relation to trauma and inflammation by evaluating their effects on microvascular perfusion and permeability in mouse brain and in cat skeletal muscle. PGI2 and NO are endogenous vasoactive substances produced by the endothelium. They are vasodilators with antiaggregatory/antiadhesive and permeability-redu
