Long- and short-term effects of mercury pollution on the soil microbiome

Despite the toxicity of mercury (Hg) for organisms in the environment, little is known on its impact on the soil microbiome, especially its chronic effect. Here, we assessed the effects of a long-term contamination of Hg in soils on the bacterial and fungal communities along a gradient of contamination from no to high contamination. Short-term reactions (30 days) of the microbial communities in th

Developing Life Cycle Sustainability Assessment methodology by applying values-based sustainability weighting - Tested on biomass based and fossil transportation fuels

The production and use of transportation fuels can lead to sustainability impacts. Assessing them simultaneously in a holistic way is a challenge. This paper examines methodology for assessing the sustainability performance of products in a more integrated way, including a broad range of social impacts. Life Cycle Sustainability Assessment (LCSA) methodology is applied for this assessment. LSCA of

Temperature performance and food shelf-life accuracy in cold food supply chains – Insights from multiple field studies

A challenge in perishable food industry today is variable and unknown food quality caused by different temperature conditions. This sometimes leads to unreliable printed shelf lives (best before dates) and food waste. Hence, temperature monitoring and control along cold food supply chains (FSCs) are essential for maintaining food quality and safety of perishable food products. This paper evaluates

Will You Intermarry Me? : Determinants and Consequences of Immigrant-Native Intermarriage in Contemporary Nordic Settings

This dissertation examines the determinants and consequences of immigrant-native intermarriage in two Nordic countries, Sweden and Denmark, between 1980 and 2011. An increase in immigration during the second half of the twentieth and early twenty-first century in the countries under study was accompanied by an increase in intermarriage. However, the marriages of natives and some immigrant groups a

Palaeoenvironments, palaeoecology and palaeobiogeography of Late Cretaceous (Campanian) faunas from the Kristianstad Basin, southern Sweden, with applications for science education

I den andra delen av avhandlingen introduceras några konkreta förslag på tillämpningar av paleontologisk kunskap generellt, och forskningsresultat om fossil från Kristianstadsområdet specifikt, som kan användas i undervisning från förskola till gymnasieskola med undervisningsförslag inom de tre områdena; fossil och dinosaurier i förskolan, tidslinjer för utveckling av tidsmedvetenhet samt geovetenThis thesis is thematically divided into two sections: Part1 presents studies related to the palaeoenvironments,palaeoecology and palaeobiogeography of the LateCretaceous (Campanian) faunas from the KristianstadBasin of southern Sweden; Part 2 reports on applicationsof palaeontological research for science education inschools.Part 1 was based on personally conducted fieldworkand biostratigraphical

Multisensory stimulation improves functional recovery and resting-state functional connectivity in the mouse brain after stroke

Stroke causes direct structural damage to local brain networks and indirect functional damage to distant brain regions. Neuroplasticity after stroke involves molecular changes within perilesional tissue that can be influenced by regions functionally connected to the site of injury. Spontaneous functional recovery can be enhanced by rehabilitative strategies, which provides experience-driven cell s

Variation in the Photocurrent Response Due to Different Emissive States in Methylammonium Lead Bromide Perovskites

Thin films and crystals of methylammonium lead bromide (MAPbBr3) perovskites have strong photoluminescence (PL). Previous studies have shown that the emission arises from different states. However, the role of these states in the performance of a solar cell has not been reported. We have used photocurrent and photoluminescence microscopies (PCM and PLM) to investigate the correlation between the p

Familial Risks between Urolithiasis and Cancer

© 2018 The Author(s). Urolithiasis (UL, urinary tract stone disease) has been reported to increase subsequent cancers in the urinary tract. Recently, we showed data that surveillance bias may be an important confounder in the reported associations. In the present approach we want to address the question of possible cancer risk posed by UL mechanistically. Both UL and cancer have strong genetic com

Coverage-dependent oxidation and reduction of vanadium supported on anatase TiO2(1 0 1)

© 2018 Elsevier Inc. Using a multi-technical approach, we studied the oxidation of anatase TiO 2 (1 0 1)-supported vanadium (V) clusters at room temperature. We found by ex situ XPS that the highest oxidation state is +4 at sub-monolayer coverage regardless of the O 2 pressure, and STM studies revealed that the initial oxidation proceeds through oxygen-induced disintegration of V clusters into mon

Inverse analyses of effective diffusion parameters relevant for a two-phase moisture model of cementitious materials

Here we present an inverse analyses approach to determining the two-phase moisture transport properties relevant to concrete durability modeling. The purposed moisture transport model was based on a continuum approach with two truly separate equations for the liquid and gas phase being connected by the sorption kinetics. The moisture properties of ten binder-systems containing fly ash, calcined cl

Evaluation of an assessment instrument for a sexual health curriculum for nurses and midwifery students in Tanzania : The sexual health education professionals scale (SHEPS)

We assessed the structure and content of a new scale, the SHEPS, to assess change in sexual health confidence, knowledge and attitudes in nursing and midwifery students following an intervention (a 2-day standardized workshop on sexual health). Students were 78 Tanzanian nursing and midwifery students attending a University of Health Sciences, who were assessed immediately before and after the wor

Discovery of Small Molecules That Induce Lysosomal Cell Death in Cancer Cell Lines Using an Image-Based Screening Platform

The lysosomal cell death (LCD) pathway is a caspase 3-independent cell death pathway that has been suggested as a possible target for cancer therapy, making the development of sensitive and specific high-throughput (HT) assays to identify LCD inducers highly desirable. In this study, we report a two-step HT screening platform to reliably identify such molecules. First, using a robust HT primary sc

Too Young to Die: Regression Discontinuity of a Two-Part Minimum Legal Drinking Age Policy and the Causal Effect of Alcohol on Health

This study examines the impact of Sweden’s unique two-part Minimum Legal Drinking Age (MLDA) policy on alcohol consumption and health using regression discontinuity design. In Sweden on-licence purchasing of alcohol is legalised at 18 and off-licence purchasing is legalised later at 20 years of age. We find an immediate and significant 6% jump in participation and a larger increase in number of da

Sensitive detection of lysosomal membrane permeabilization by lysosomal galectin puncta assay

Lysosomal membrane permeabilization (LMP) contributes to tissue involution, degenerative diseases, and cancer therapy. Its investigation has, however, been hindered by the lack of sensitive methods. Here, we characterize and validate the detection of galectin puncta at leaky lysosomes as a highly sensitive and easily manageable assay for LMP. LGALS1/galectin-1 and LGALS3/ galectin-3 are best suite

Lysosomal cell death at a glance

Lysosomes serve as the cellular recycling centre and are filled with numerous hydrolases that can degrade most cellular macromolecules. Lysosomal membrane permeabilization and the consequent leakage of the lysosomal content into the cytosol leads to so-called "lysosomal cell death". This form of cell death is mainly carried out by the lysosomal cathepsin proteases and can have necrotic, apoptotic

Identification of Cytoskeleton-Associated Proteins Essential for Lysosomal Stability and Survival of Human Cancer Cells

Microtubule-disturbing drugs inhibit lysosomal trafficking and induce lysosomal membrane permeabilization followed by cathepsin-dependent cell death. To identify specific trafficking-related proteins that control cell survival and lysosomal stability, we screened a molecular motor siRNA library in human MCF7 breast cancer cells. SiRNAs targeting four kinesins (KIF11/Eg5, KIF20A, KIF21A, KIF25), my
