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

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 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
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
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.
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
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)
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-
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
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
Background: Standard anti-proliferative chemotherapy is relatively ineffective against slowly proliferating androgen-independent prostate cancer cells within metastatic sites. In contrast, the lipophilic cytotoxin thapsigargin, which causes apoptosis by disrupting intracellular free Ca2+ levels, is effective against both proliferative and quiescent (i.e., G(0)-arrested) cells. However, thapsigargi
Asthma and chronic obstructive pulmonary disease (COPD) both have a high prevalence worldwide and yet each condition remains underdiagnosed. Despite a number of common features, these inflammatory respiratory syndromes have distinct clinical outcomes. COPD represents a greater economic burden than asthma because it has a less favourable prognosis and is associated with greater morbidity and mortal
The kinetic properties of dUTPase from equine infectious anemia virus (EIAV) were investigated. KM (1.1 [plusmn] 0.1 [mu ]M) and kcat (25 s[minus ]1) were found to be independent of pH in the neutral pH range. Above pH 8.0, KM increases slightly. Below pH 6.0, the enzyme is rapidly deactivated. Detergent was found to enhance activity, leaving KM and kcat unaffected. Compared to the Escherichia col
We have fit synthetic visibilities from three-dimensional ((COBOLD)-B-5+PHOENIX) and one-dimensional (PHOENIX, ATLAS 12) model stellar atmospheres of Procyon (F5 IV) to high-precision interferometric data from the VLT Interferometer (K band) and from the Mark III interferometer (500 and 800 nm). These data sets provide a test of theoretical wavelength-dependent limb-darkening predictions. The work
