Family history of type 1 and type 2 diabetes and risk of latent autoimmune diabetes in adults (LADA)

Background: A family history of diabetes (FHD) is a strong predictor of diabetes risk, yet has rarely been investigated in latent autoimmune diabetes in adults (LADA). This study therefore investigated the risk of LADA and type 2 diabetes (T2D) in relation to FHD, taking into account the type of diabetes in relatives. Methods: Data from a population-based study were used, including incident cases

Strategies for building resilience to hazards in water, sanitation and hygiene (WASH) systems : The role of public private partnerships

The aim of this paper is to enhance understanding of how the resilience of water, sanitation and hygiene (WASH) systems to hazards can be improved. In turn, this aims to inform different strategies for public and private partnerships (PPPs). In a new approach, to acknowledge the multi levelled nature of resilience; risk at the relevant levels are taken into account, (regional/river basin, urban ar

Human modification of global water vapor flows from the land surface

It is well documented that human modification of the hydrological cycle has profoundly affected the flow of liquid water across the Earth's land surface. Alteration of water vapor flows through land-use changes has received comparatively less attention, despite compelling evidence that such alteration can influence the functioning of the Earth System. We show that deforestation is as large a drivi

Multiscale Modelling of Lytic Polysaccharide Monooxygenases

Lytic polysaccharide monooxygenase (LPMO) enzymes have attracted considerable attention owing to their ability to enhance polysaccharide depolymerization, making them interesting with respect to production of biofuel from cellulose. LPMOs are metalloenzymes that contain a mononuclear copper active site, capable of activating dioxygen. However, many details of this activation are unclear. Some aspe

A practical method for measuring the ion exchange capacity decrease of hydroxide exchange membranes during intrinsic degradation

In this work we present a practical thermogravimetric method for quantifying the IEC (ion exchange capacity) decrease of hydroxide exchange membranes (HEMs) during intrinsic degradation mainly occurring through nucleophilic attack of the anion exchanging group by hydroxide ions. The method involves measuring weight changes under controlled temperature and relative humidity. These conditions are cl

Force measurements in stiff, 3D, opaque granular materials

We present results from two experiments that provide the first quantification of inter-particle force networks in stiff, 3D, opaque granular materials. Force vectors between all grains were determined using a mathematical optimization technique that seeks to satisfy grain equilibrium and strain measurements. Quantities needed in the optimization - the spatial location of the inter-particle contact

Diffusion kurtosis imaging of gliomas grades II and III - A study of perilesional tumor infiltration, tumor grades and subtypes at clinical presentation

Diffusion kurtosis imaging (DKI) allows for assessment of diffusion influenced by microcellular structures. We analyzed DKI in suspected low-grade gliomas prior to histopathological diagnosis. The aim was to investigate if diffusion parameters in the perilesional normal-appearing white matter (NAWM) differed from contralesional white matter, and to investigate differences between glioma malignancy

Functional studies of chronic lymphocytic leukemia B cells expressing β2-integrin type complement receptors CR3 and CR4

The expression and role of CR3 (CD11b/CD18) and CR4 (CD11c/CD18) in B cells are not yet explored in contrast to myeloid cells, where these β2-integrin type receptors are known to participate in various cellular functions, including phagocytosis, adherence and migration. Here we aimed to reveal the expression and role of CR3 and CR4 in human B cells. In B cells of healthy donors CR3 and CR4 are sca

Analysis of the heterogeneity in treatment response to Donepezil in Alzheimer’s disease conclusions from the Swedish Alzheimer Treatment Study Group.

In many of the first treatment trials with tacrine, heterogeneity in treatment response was observed and discussed. One third of the patients were considered to be responders to treatment, one third unchanged and one third non-responders. Factors outlined as possible positive predictors of treatment were among others old age, well preserved frontal lobes, and presence of the APOE e4 allele. Unfort

Multicenter patch testing with methylisothiazolinone and methylchloroisothiazolinone/methylisothiazolinone within the international contact dermatitis research group

Background: The preservatives methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) and MI are well-known contact sensitizers. Recently, an increase in the contact allergy frequency for MI 0.2% aqueous (aq) has been seen in many European countries paralleled with an increase in MCI/MI allergy. Many of the MI-allergic patients do not react to MCI/MI 0.01% or 0.02% because the concentration of

PARP1 expression and its correlation with survival is tumour molecular subtype dependent in glioblastoma

Overexpression of PARP1 exists in various cancers, including glioblastoma (GBM). Although PARP1 inhibition is a promising therapeutic target, no comprehensive study has addressed PARP1's expression characteristics and prognostic role regarding molecular heterogeneity in astrocytomas including GBM. Our aim was to evaluate PARP1's associations with survival, WHO grade, lineage specific markers, and

Treatment and suicide in severe depression. A case-control study on antidepressant therapy at last contact before suicide

Treatment at last contact in 89 persons with severe depression who committed suicide was compared with treatment at a corresponding date in 89 matched persons who did not commit suicide. No difference in electroconvulsive therapy use or prescription of antidepressant medication could be shown between those who committed suicide and those who did not. Neither was there a difference in response to t

A generalization of the sparse iterative covariance-based estimator

In this work, we extend the popular sparse iterative covariance-based estimator (SPICE) by generalizing the formulation to allow for different norm constraint on the signal and noise parameters in the covariance model. For any choice of norms, the resulting generalized SPICE method enjoys the same benefits as the regular SPICE method, including being hyperparameter free, although the choice of nor

Fundamental debates and policy choices for supporting innovation in Africa

Over the past three decades, a range of attempts have been made to raise the importance of science, technology and innovation on the policy agenda in Africa. This article explores four themes along which growth paths and patterns may be realized, namely regional and global integration, inclusive innovation, priorities and approaches to diversify African economies, and the role of the state. The ou
