Multicenter reproducibility of quantitative susceptibility mapping in a gadolinium phantom using MEDI+0 automatic zero referencing

Purpose: To determine the reproducibility of quantitative susceptibility mapping at multiple sites on clinical and preclinical scanners (1.5 T, 3 T, 7 T, and 9.4 T) from different vendors (Siemens, GE, Philips, and Bruker) for standardization of multicenter studies. Methods: Seven phantoms distributed from the core site, each containing 5 compartments with gadolinium solutions with fixed concentra

Lactobacillus reuteri NAD(P)H oxidase : Properties and coexpression with propanediol-utilization enzymes for enhancing 3-hydroxypropionic acid production from 3-hydroxypropionaldehyde

Lactobacillus reuteri metabolizes glycerol through propanediol-utilization (Pdu) pathway to 1,3-propanediol (1,3-PD) via 3-hydroxypropionaldehyde (3-HPA) as intermediate. In the resting cells, the oxidized co-factor obtained in the reaction is regenerated by simultaneous oxidation of 3-HPA to 3-hydroxypropionic acid (3-HP) using propionaldehyde dehydrogenase (PduP), phosphotransacylase (PduL) and

The effects of fixed-strategy agents on local convention emergence in multi-agent systems

Achieving coordination in multi-agent systems has previously been found to be possible by utilizing local conventions as opposed to relying on the emergence of global conventions. On another note, fixed-strategy agents have been researched to manipulate the behaviour of networks with global conventions, but not local conventions. This paper studies how fixed-strategy agents impact local convention

Dendrimer‐amyloid Aggregates Morphology and Cell Toxicity

Dendrimers are branched polymeric structures that have been shown to have a promising antiamyloidogenic potential by interfering with the polymerization process leading to the formation of the amyloid aggregates related to conformational diseases, such as Alzheimer's and prion diseases. It has been established that there is a relationship between the morphology of the amyloid aggregates and the am

Body composition in the elderly estimated with an electrical impedance method.

The purpose of the present study was to test the reliability and validity of a new electrical impedance method for estimating body composition in 35 healthy persons and patients in different sex and age groups, and to obtain basal data on the size of different body composition compartments in elderly individuals in health and disease. The reliability studies showed no significant differences with

Strikes and local politics

Conflicts in the labour market are detrimental to economic growth and welfare. Sweden was among the countries with the highest incidents of industrial disputes in the 1920s, but experienced declining levels from the 1930s onward. Using Swedish data from 1919 to 1938, this column shows that towns with both powerful unions and strong Social Democratic presence experienced labour market peace. The re

Without coal in the age of steam and dams in the age of electricity : An explanation for the failure of Portugal to industrialize before the Second World War

We provide a natural resource explanation for the divergence of the Portuguese economy relative to other European countries before the Second World War, based on a considerable body of contemporary sources. First, we demonstrate that a lack of domestic resources meant that Portugal experienced limited and unbalanced growth during the age of steam. Imports of coal were prohibitively expensive for i

Economic Evaluation of Management of Dementia Patients - A Systematic Literature Review

Objective: The objective is to systematically review the literature on economic evaluations of the interventions for the management of dementia and Alzheimer patients in home, hospital or institutional care. Methods: A systematic search of published economic evaluation studies in English was conducted using specified key words in relevant databased and websites. Data extracted included methods and
