1,9-Nonanedioic acid is one of the valuable building blocks for producing polyesters and polyamides. Thereby, whole-cell biosynthesis of 1,9-nonanedioic acid from oleic acid has been investigated. A recombinant Corynebacterium glutamicum, expressing the alcohol/aldehyde dehydrogenases (ChnDE) of Acinetobacter sp. NCIMB 9871, was constructed and used for the production of 1,9-nonanedioic acid from

In this paper, computation fluid dynamics (CFD) simulations are performed to describe the effect of in-cylinder flow structures on the formation and oxidation of soot in a swirl-supported light-duty diesel engine. The focus of the paper is on the effect of swirl motion and injection pressure on late cycle soot oxidation. The structure of the flow at different swirl numbers is studied to investigat

Background: Severe inflammatory airway diseases are associated with inflammation that does not resolve, leading to structural changes and an overall environment primed for exacerbations. Objective: We sought to identify and inhibit pathways that perpetuate this heightened inflammatory state because this could lead to therapies that allow for a more quiescent lung that is less predisposed to sympto

Restraint stresses appear in structural parts which are prevented from adjusting their shape when subjected to e.g. shrinkage or thermal actions. If the restrained stresses are large, cracking might occur, which can affect the durability of the structure. In the case of restraint effects, the reinforcement required in a bridge to limit the crack widths can be difficult to determine, as the magnitu

We study two-dimensional eigenvalue ensembles close to certain types of singular points in the interior of the droplet. We prove existence of a microscopic density which quickly approaches the equilibrium density, as the distance from the singularity increases beyond the microscopic scale. This kind of asymptotic is used to analyze normal matrix models in [3]. In addition, we obtain here asymptoti

Following intense research efforts, modulation of the immune system has finally proved to be a viable approach for treating malignant disease. Recently, chimeric antigen receptor redirected T cells have achieved promising outcomes in patients with B-cell malignancies and they are currently also being investigated in other haematological malignancies, solid tumours and viral infections. Compared wi

Aim: Attention-deficit/hyperactivity disorder (ADHD) is the most common diagnosis within child- and adolescent psychiatry. Waiting lists and delayed care are major issues. The aim was to evaluate if standardized care (SC) for assessment and treatment of uncomplicated ADHD would reduce resource utilization and increase satisfaction with preserved improvement within the first year of treatment. Meth

We present a new algorithm for solving the LPN problem. The algorithm has a similar form as some previous methods, but includes a new key step that makes use of approximations of random words to a nearest codeword in a linear code. It outperforms previous methods for many parameter choices. In particular, we can now solve the (512,18) LPN instance with complexity less than 2 80 operations in expec

A dominating set of a graph G is a set D⊆ VG such that every vertex in VG- D is adjacent to at least one vertex in D, and the domination number γ(G) of G is the minimum cardinality of a dominating set of G. A set C⊆ VG is a covering set of G if every edge of G has at least one vertex in C. The covering number β(G) of G is the minimum cardinality of a covering set of G. The set of connected graphs

The scientific debate following the initial formulation of the “bad luck” hypothesis in cancer development highlighted how measures based on analysis of variance are inappropriately used for risk communication. The notion of “explained” variance is not only used to quantify randomness, but also to quantify genetic and environmental contribution to disease in heritability coefficients. In this pape

Erlotinib (Tarceva) targets the epidermal growth factor receptor (EGFR), which is commonly overexpressed in human cancers, including lung cancer. We show that erlotinib can be labeled with [(11)C] by reacting the normethyl precursor with [(11)C]-methyl iodide. By using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide proliferation assay, two lung cancer cell lines (A549 and NCI358)

Partially premixed combustion (PPC) is one of several advanced combustion concepts for the conventional diesel engine. PPC uses a separation between end of fuel injection and start of combustion, also called ignition dwell, to increase the mixing of fuel and oxidizer. This has been shown to be beneficial for simultaneously reducing harmful emissions and fuel consumption. The ignition dwell can be

Speed control is the most important aspect of promoting road safety world-wide. The question is how are speeds developing? The European Transport Safety Council concludes: There is little progress on reducing speeds in Europe. Similar conclusions can be drawn from the US and Australia. Attitude surveys show that people’s answers are not very consistent and represent statements without any strong b

BACKGROUND: The epidermal growth factor (EGF) receptors HER2 and HER4 and the ligands HB-EGF and NRG1 are crucial for heart development. The purpose of our study was to investigate the role of the complete EGF system in relation to hypoxia of the heart.METHODOLOGY/PRINCIPAL FINDINGS: We examined the mRNA expression by real time PCR of the 4 receptors and 12 ligands from the EGF-system in paired no

PURPOSE: The goal of this study was to identify proteins down-regulated during bladder cancer progression.EXPERIMENTAL DESIGN: By using comparative proteome analysis and measurement of mRNA, we found a significant down-regulation of S100C, a member of the S100 family of proteins, in T24 (grade 3) as compared with RT4 (grade 1) bladder cancer cell lines. Moreover, quantification of the mRNA level r
