As the total cost of renewable electricity falls lower than the price of fossil fuel, not only can electricity be used to replace fossil fuels using batteries in vehicles but it can also be used to produce fuels. This makes it possible to replace fuels in sectors not easily directly electrified. It also provides new ways of balancing the electricity system. When renewable electricity is cheap a lo

Glycophospholipids combine the structural versatility of phospholipids and carbohydrates, but their potential as excipients and performance in other related applications remains largely unexplored due to their low natural abundance. We have synthesized four novel phosphatidyl saccharide conjugates with different carbohydrate head groups; glucose, galactose, fructose and xylose by using a Phospholi

Cytokines provide signals that regulate immature normal and acute myeloid leukemia (AML) cells in the bone marrow microenvironment. We here identify interleukin 4 (IL4) as a selective inhibitor of AML cell growth and survival in a cytokine screen using fluorescently labeled AML cells. RNA-sequencing of the AML cells revealed an IL4-induced upregulation of Stat6 target genes and enrichment of apopt

Adhesion is a key component of hematopoietic stem cell regulation mediating homing and retention to the niche in the bone marrow. Here, using an RNA interference screen, we identify cytohesin 1 (CYTH1) as a critical mediator of adhesive properties in primary human cord blood-derived hematopoietic stem and progenitor cells (HSPCs). Knockdown of CYTH1 disrupted adhesion of HSPCs to primary human mes

In vitro and animal studies suggest that bioactive constituents of coffee and tea may have anticarcinogenic effects against cutaneous melanoma; however, epidemiological evidence is limited to date. We examined the relationships between coffee (total, caffeinated or decaffeinated) and tea consumption and risk of melanoma in the European Prospective Investigation into Cancer and Nutrition (EPIC). EP

The protection of trade secrets in Portugal and Spain has been derived from general legal principles (of Civil Law, Penal Law and Unfair Marketing Law). This chapter on implementation of the Trade Secrets Directive (TS Directive) in Portugal and Spain presents the traditional views and positions and the implementation of the TS Directive into the respective national legal orders.In Portugal, imple

Background: Residual tumor volume (RTV) and extent of resection (EOR) have previously been shown to affect survival in glioblastoma (GB) patients. Quantitative radiological assessment (QRA) of these factors could potentially affect clinical decision-making in the postoperative period. Purpose: The first aim was to evaluate the reproducibility of different volume estimation methods of RTV and EOR b

The study of biological mechanisms involved in human fetal brain development requires suitable models. To date, most findings have been acquired from animal models that fail to account for human-specific developmental traits. To counteract this limitation, a novel in vitro model is proposed where human pluripotent stem cells are differentiated into a coherent fetal brain tissue in a gradient formi

Nanoplastics are emerging environmental contaminants that increasingly threaten soil ecosystems, yet their effects on microbial behavior remain poorly understood. This is mainly due to the lack of experimental tools capable of directly observing microbial dynamics in situ under realistic soil-like conditions. Here, we present a proof-of-concept system that enables real-time, high-throughput monito

Smart microscopy represents a paradigm shift in biological imaging, moving from passive observation tools to active collaborators in scientific inquiry. Enabled by advances in automation, computational power, and artificial intelligence, these systems are now capable of adaptive decision-making and real-time experimental control. Here, we introduce a theoretical framework that reconceptualises sma

Low back pain is common and negatively impacts quality of life and workplace productivity. However, few studies have focused on small- and medium-sized enterprises (SMEs) where risk factors are prevalent. This cross-sectional study examined the association and structural relationships between physical and social factors in low back pain among Japanese SME workers. We analyzed survey data collected

Alzheimer’s disease (AD) accounts for about 70% of neurodegenerative diseases and is a cause of cognitive decline and death for one-third of seniors. AD is currently underdiagnosed, and it cannot be effectively prevented. Aggregation of amyloid-β (Aβ) proteins has been linked to the development of AD, and it has been established that, under pathological conditions, Aβ proteins undergo structural c

An economic model describing manufacturing costs is implemented within the frame of a case study. The implemented economic model is developed to enable analyses of the cost items and parameters influencing the cost of a part or a batch and also to make simulations for the purpose of investigating the economic outcome of future development activities. The aim of the case study was to identify activ

Parvalbumin- (PV-) containing basket cells constitute perisomatic GABAergic inhibitory interneurons innervating principal cells at perisomatic area, a strategic location that allows them to efficiently control the output and synchronize oscillatory activity at gamma frequency (30–90 Hz) oscillations. This oscillatory activity can convert into higher frequency epileptiform activity, and therefore c

Emissions of greenhouse gases in all sectors of society must reach near zero, in developed countries preferably by 2050, in order to reach climate policy objectives. Alternatives and strategies for the energy and transport sectors are relatively well understood but the basic industries are often overlooked, not least in sustainability transition and innovation system studies. The policy and techn

Self-renewal of hematopoietic stem cells (HSCs) and leukemia-initiating cells (LICs) has been proposed to be influenced by low oxygen tension (hypoxia). This signaling, related to the cellular localization inside the bone marrow niche and/or influenced by extrinsic factors, promotes the stabilization of hypoxia inducible factors (HIFs). Whether HIF-1α can be used as a therapeutic target in the tre

Acquisition of homozygous activating growth factor receptor mutations might accelerate cancer progression through a simple gene-dosage effect. Internal tandem duplications (ITDs) of FLT3 occur in approximately 25% cases of acute myeloid leukemia and induce ligand-independent constitutive signaling. Homozygous FLT3-ITDs confer an adverse prognosis and are frequently detected at relapse. Using a mou

Popular Abstract in Swedish Avhandlingen består av en inledning och 4 artiklar. Den första artikeln, Young people and alcohol: an econometric analysis, analyser bestämningsfaktorerna för ungdomars konsumtion av alkohol ur ett hälsoekonomiskt perspektiv. Huvudresultatet i artikeln är att ungdomar som har föräldrar som är villiga att tillhandahålla alkohol till dem är mer benägna att dricka alkohol,This thesis consists of four essays on risky health behaviour among adolescents. In the first paper, Young people and alcohol: an econometric analysis, the purpose was to analyse the determinants of adolescent drinking behaviour within an economic-theoretical framework. The results showed that having parents willing to supply alcohol increased the frequency of beer-, wine-, and spirits-consumption
