Background Lactobacillus reuteri converts glycerol to 3-hydroxypropionic acid (3HP) and 1,3-propanediol (1,3PDO) via 3-hydroxypropionaldehyde (3HPA) as an intermediate using enzymes encoded in its propanediol-utilization (pdu) operon. Since 3HP, 1,3PDO and 3HPA are important building blocks for the bio-based chemical industry, L. reuteri can be an attractive candidate for their production. However
B vitamins and polymorphisms in genes coding for enzymes involved in one-carbon metabolism may affect DNA synthesis and methylation and thereby be implicated in carcinogenesis. Previous data on vitamins B2 and B6 and genetic polymorphisms other than those involving MTHFR as risk factors for gastric cancer (GC) are sparse and inconsistent. In this case-control study nested within the European Prosp
The term gastrointestinal neuromuscular disease describes a clinically heterogeneous group of disorders of children and adults in which symptoms are presumed or proven to arise as a result of neuromuscular, including interstitial cell of Cajal, dysfunction. Such disorders commonly have impaired motor activity, i.e. slowed or obstructed transit with radiological evidence of transient or persistent
In this work the synthesis of waterborne polyurethane/nanosilica nanocomposites by using two differ-ent strategies is presented, starting from a vinyl terminated polyurethane prepolymer (PUP) based onisophorone diisocyanate and polypropylene glycol, and varying the nanosilica content. In one case, thePUP was dispersed in an aqueous solution containing glycerol-functionalized colloidal nanosilica p
Background: Mass screening for celiac disease (CD) as a public health intervention is controversial. Prior to implementation, acceptability to the targeted population should be addressed. We aimed at exploring adolescents' and parents' experiences of having the adolescents' CD detected through mass screening, and their attitudes towards possible future mass screening. Methods: All adolescents (n =
In this work we have calculated U from first principles for the early lanthanides (Ce-Gd) using the constrained random phase approximation (cRPA). We compare the static limit of U with experimental estimations from x-ray photoemission spectroscopy (XPS) and bremsstrahlung isochromat spectroscopy (BIS) spectra and also discuss the frequency dependence of U across the series. The localized subspace
Prediction of the in-plane biaxial strength of paper by the Tsai-Wu failure criterion has in general proved to be in good agreement with experimental data. However, the Tsai-Wu criterion overestimates the strength in some parts of the biaxial tension region. This shortcoming can be corrected by adding a pair of cubic terms to the existing Tsai-Wu criterion. The modified Tsai-Wu criterion presented
Indolyl substituted pyranyl- and cyclohexenyl molybdenum complexes were synthesised through stereoselective nucleophilic addition of indoles to the corresponding cationic 2H-pyran or cyclohexadiene molybdenum complex. Decomplexation of an allylic molybdneum complex by treatment with iodine gave 1-(4-iodo-2-cyclohexenyl)-1H-indole-3-carbonitrile in high regio-selectivity. A new method for preparati
Abstract in UndeterminedThe report is an evaluation of five years of Linnaeus-Palme exchange programme between the chemistry departments at University of Gothenburg, Sweden and University of the West Indies, Jamaica. The exchange programme gives students and teachers at the two universities the possibility to study and teach at the partner university to better understand the international implicat
In a prospective study comprising 310 consecutive patients with carcinoma of the cervix, FIGO stages I-IV, the prognostic significance of clinical and flow cytometric variable was evaluated in a univariate and multivariate analysis. The parameters studied included stage according to FIGO, age, histopathologic grade according to Ackerman and MGS scores, DNA ploidy, S-phase fraction as well as treat
C4b-binding protein (C4BP), an important inhibitor of complement activation, has a unique spider-like shape. It is composed of six to seven identical alpha-chains with or without a single beta-chain, the chains being linked by disulfide bridges in their C-terminal parts. To elucidate the structural requirements for the assembly of the alpha-chains, recombinant C4BP was expressed in HEK 293 cells.
Analytic expression for the exact bit error probability of the (7,5) convolutional code was discussed. Recursive systematic encodes which became especially important as component encoders in concatenated coding schemes were also studied. This technique can calculate the probability distribution of the output log-likelihood ratios of the Max-Log-MAP algorithm in analytic form.
In the development of new food products, more knowledge is needed about the occurrence and quantity of food-borne pathogens in the food chain to be able to implement effective control measures and assure food safety. In addition, improved understanding of how environmental factors and food preservatives effect the microbial virulence expression in foods will enable the formulation of new strategie
In addition to being a key criterion of the sustainable development proviso, for business, the integration of social- and ecological considerations into decision-making is of growing importance for minimising future environmentally-related risk and associated economic costs, as well as gaining a share in growing markets favouring products and companies focusing upon social responsibility and ecolo
In an era of lifelong learning, empowerment of the learner becomes fundamental. Therefore ex-ploitation of the full potential of learning objects depends upon creation of an appropriate infra-structure to promote symmetrical control of inquiry. The learner needs to be empowered because learning is a discovery process and thus must be under his or her own control. In early stages of education it
