New structural chromosomal rearrangements in congenital leukemia

The karyotypic abnormalities and clinical data on three patients in whom acute leukemia was diagnosed within the first 6 months of life are presented. The four structural chromosomal rearrangements detected in the bone marrow from these patients, i.e., t(7;12)(q36;p13) and t(1;19)(q11;q11) in case 1, t(2;10;11;12)(q21q31;p13;q13;q24) in case 2, and t(11;19)(q23;p13) in case 3, have not previously

Carriage of penicillin-resistant Streptococcus pneumoniae by children in day-care centers during an intervention program in Malmo, Sweden

BACKGROUND: An increasing incidence of penicillin-resistant Streptococcus pneumoniae (PRP) was detected in Malmo in 1994. OBJECTIVE: To evaluate clonality and factors facilitating the spread of PRP among children in day-care centers (DCCs). METHODS: We used phenotypic and DNA-fingerprinting methods in conjunction with epidemiologic data from the South Swedish Pneumococcal Intervention Project's in

Measurements of the interaction cross sections for Ar and Cl isotopes

We have measured the interaction cross sections (σI) of 31–40Ar and 31–37Cl on carbon targets at energies of around 950 A MeV. The effective matter radii for these nuclei were deduced by a Glauber-model analysis. Combining our matter radii with measured charge radii for Ar isotopes, we could deduce the proton-skin thicknesses for the 32–40Ar isotopes, which were found to increase monotonically wit

A fishy mosasaur: the axial skeleton of Plotosaurus (Reptilia, Squamata) reassessed

The concept of convergence, that is, how unrelated animals independently evolve similar morphological traits, is a fundamental aspect of evolution. Hitherto, the Mesozoic ichthyosaurs were regarded as the sole obligate marine reptiles that achieved a fully streamlined body and a semilunate tail fluke. However, analyses of vertebral centrum morphometrics and process orientation have revealed that a

Transport and sorption phenomena in concrete and other porous media

The work presented in this thesis is mainly focused on transport processes involved in service life predictions of concrete. Two papers and three reports deal with ion transport in pore solution of concrete. One paper and one report deals with moisture transport in concrete and the remaining papers and reports deal with absorption and physical properties related to adsorption for different materia

Chlorophyll biosynthesis in higher plants. Regulatory aspects of 5-aminolevulinate formation

Chlorophyll, heme, phytochrome and siroheme biosynthesis in higher plants is regulated by the supply of their precursor 5-aminolevulinate (ALA), which is derived from glutamate. Glutamate conversion to ALA occurs only in the plastid and requires chloroplast coded tRNA(Glu) and nuclear coded glutamyl-tRNA synthetase, glutamyl-tRNA reductase and glutamate 1-semialdehyde aminotransferase. The chromos

Integral equation for spin dependent unintegrated parton distributions incorporating double In-2(1/x) effects at low x

In this paper we derive an integral equation for the evolution of unintegrated (longitudinally) polarized quark and gluon parton distributions. The conventional Catani-Ciafaloni-Fiorani-Marchesini (CCFM) framework is modified at small x in order to incorporate the QCD expectations concerning the double ln(2)(1/x) resummation at low x for the integrated distributions. Complete Altarelli-Parisi spli

Lifetime measurements for ground term transitions in TaII, WII, and ReII

Lifetime measurements have been made for the radiation emitted in the ground term transitions of the nominal form 5s(2)5p(6)5d(x)6s-5s(2)5p(6)5d(x)6p in Ta II (x = 3), W II (x = 4), and Re II (x = 5). Supporting theoretical calculations have also been performed to characterize configuration interaction and to estimate the degree of decay branching of the upper levels. The lifetime measurements hav

Novel properties of antimicrobial peptides

Endogenous peptide antibiotics are known as evolutionarily old components of innate immunity. Due to interaction with cell membrane these peptides cause permeabilization of the membrane and lysis of invading microbes. However, some studies proved that antimicrobial peptides are universal multifunctional molecules and their functions extend far beyond simple antibiotics. In this review we present a

Småhus med installationsgrund: utvärdering av experimenthus i Halmstad

I denna rapport redovisas resultaten från mätningar utförda i ett experimenthus i Halmstad som är grundlagt med den så kallade installationsgrunden enligt EG-2000 konceptet. Insamlade mätdata används för beräkningar av energianvändningen och energibalansen. Energianvändningen i experimenthuset jämförs med energianvändningen i ett liknande hus grundlagt med platta på mark.

Satiation effects in piscivore prey size selection

We present a functional response model that primarily evaluates effects of satiation in piscivore prey-size selection. The model also includes other passive processes, such as prey-size-dependent encounter rate and prey-size-dependent capture success, where capture success decreases and encounter rate increases with prey size. The model generates a wide variety of outcomes, where small, intermedia

Optimizing conditions for poly(beta-hydroxybutyrate) production by Halomonas boliviensis LC1 in batch culture with sucrose as carbon source

Halomonas boliviensis LC1 is able to accumulate poly(beta-hydroxybutyrate) (PHB) under conditions of excess carbon source and depletion of essential nutrients. This study was aimed at an efficient production of PHB by growing H. boliviensis to high cell concentrations in batch cultures. The effect of ammonium, phosphate, and yeast extract concentrations on cell concentration [cell dry weight (CDW)

External costs and taxes in heat supply systems

A systems approach was used to compare different heating systems from a consumer perspective. The whole energy system was considered from natural resources to the required energy services. District heating, electric heat pumps, electric boilers, natural-gas-, oil- or pellet-fired local boilers were considered when supplying heat to a detached house. The district heat production included wood-chip-

Palliative care as a framework for older people's long-term care.

This article draws on the findings from several years of research on the health problems, quality of life and care of older people, especially during the later years of life, and argues that there is a need to develop and provide care according to the principles of palliative care. The findings indicate that palliative care, including a focus on symptom management, psychosocial and existential iss

Modelling of Drug Release from Reservoir and Matrix Formulations - Multiple Unit Dosage Forms and Swelling and Dissolving Matrix Systems

Popular Abstract in Swedish I denna avhandling behandlas modeller för simulering av läkemedelsfrisättning från enskilda filmdragerade pellets, samtidig frisättning från ett antal filmdragerade pellets, samt frisättning av läkemedel och/eller polymer från svällande polymertabletter. Modellerna är validerade mot experimentella data. Modellen för frisättning från filmdragerade pellets är validerad mIn this work, mathematical models have been developed describing drug release from film-coated reservoir systems as well as drug release and polymer dissolution from swelling and dissolving polymer tablets. The model derivation of both systems is based on a mechanistic approach. The model describing drug release from reservoir systems, i.e. from single, film-coated pellets, was validated against e
