The aim of this study is to reveal how the oil-in-water interface of triolein emulsions in aqueous solutions is affected by the lipase activity when using five different surfactants as emulsifiers. For this purpose Dynamic Light Scattering (DLS) and Small Angle X-ray Scattering (SAXS) were applied. Lipases are enzymes that catalyses the hydrolysis of ester bonds of lipids, i.e lipolysis, and act a

Preconception health status, especially of women, but also of men, is known to influence pregnancy outcomes. Despite knowledge of the growing importance of preconception health, numerous challenges remain for conducting research in this population and delivering appropriate clinical care. The 2023 Global Pregnancy Collaboration annual workshop focused on exploring preconception health as it relate

In a rapidly changing world, it is of fundamental importance to understand processes constraining or facilitating adaptation through microevolution. As different traits of an organism covary, genetic correlations are expected to affect evolutionary trajectories. However, only limited empirical data are available. We investigate the extent to which multivariate constraints affect the rate of adapta

G protein-coupled estrogen receptor (GPER), or GPR30, is a membrane receptor reported to mediate non-genomic estrogen responses. Tamoxifen is a partial agonist at GPER in vitro. Here, we investigated if GPER expression is prognostic in primary breast cancer, if the receptor is treatment-predictive for adjuvant tamoxifen, and if receptor subcellular localization has any impact on the prognostic val

Objective: Pre-clinical studies have identified marker- and tumor compartment-defined functionally distinct macrophage subsets. Our study analyzes marker-defined macrophage subsets in different tumor compartments of high-grade serous ovarian cancer (HGSC). Methods: A discovery cohort (N = 113) was subjected to immunohistochemistry (IHC) analyses. CD68-positivity was confirmed for CD11c-, CD80- and

Whether loci that influence fasting glucose (FG) and fasting insulin (FI) levels, as identified by genome-wide association studies, modify associations of diet with FG or FI is unknown. We utilized data from 15 US and European cohort studies comprising 51,289 persons without diabetes to test whether genotype and diet interact to influence FG or FI concentration. We constructed a diet score using s

Purpose: Single-photon emission computed tomography (SPECT) of striatal dopamine transporters (DAT) has been used to demonstrate presynaptic dopaminergic dysfunction and to monitor the progression of Parkinson's disease. In parkinsonian patients who were implanted with embryonic mesencephalic tissue in the striatum, positron emission tomography (PET) has shown an increase in striatal [F-18]dopa up

Methanol is an alternative fuel offering a lower well-to-wheel CO2 emission as well as a higher efficiency, given that the fuel is derived from biomass. In addition to reduced CO2, methanol does not emit soot particles when combusted which is a great advantage when attempting to reduce NOX levels due to the effectively non-existing NOX-soot trade-off. The engine setup used was a Scania D13 engine

Dredged material resulting from deepening and maintenance activities of the Aveiro Harbor inlet channel, northwestern coast of Portugal, has been used to mitigate the erosion trend recorded on nearby beaches (from Barra to Costa Nova Beach) through direct placement of sand by using standard dredge equipment. The disposal activities of dredged material have been undertaken at two main sites: betwee

A commercially available fuel, E85, a blend of ~85% ethanol and ~15% gasoline, can be a viable substitute for fossil fuels in internal combustion engines in order to achieve a reduction of the greenhouse gas (GHG) emissions. Ethanol is traditionally made of biomass, which makes it a part of the food-feed-fuel competition. New processes that reuse waste products from other industries have recently

Background: Growing evidence suggests an association between Parkinson’s disease (PD) and diabetes mellitus (DM). At the cellular level, long-term elevated levels of glucose have been shown to lead to nigrostriatal degeneration in PD models. However, the underlying mechanism is still unclear. Previously, we have elucidated the potential of type 2 diabetes mellitus (T2DM) in facilitating PD progres

In order to cater for the increasingly complex society several countries have adopted a capabilities-based planning approach, including capability assessments, as part of their preparedness for disasters. Since the number of actors who are dependent on each other is increasing, capability assessments are made based on assumptions of other actors’ capabilities. It is therefore crucial to understand

The growing proportion of green energy in the electricity grids brings with it a growing need of grid stabilizing resources to counteract the inherent intermittency of renewable energy resources. This is where the grid scale energy storages come in handy. They efficiently offset the intermittencies of solar, wind etc. resources by energy arbitrage and peak shifting. This thesis looks into the econ

Surfaktanter används inom många applikationer idag för att stabilisera eller förbättra proteiners funktion. Kartläggning av hur surfaktanter interagerar med proteiner påbörjades redan för flera årtionden sedan, men är ännu inte fullständig. Genom att förstå detta bättre kan surfaktanters användningsområden effektiviseras ytterligare och få produkter som läkemedel och rengöringsmedel som är effektiToday, proteins are used in a huge variety of industrial application ranging from detergents and pharmaceuticals to cosmetical products. Surfactants have the potential to increase solubility of poorly soluble protein, as well as hindering proteins in formulation to interact with the interface and thus protecting them from degradation. Even if the use of protein-surfactant system dates back decades

Introduction: Achieving and retaining a low background signal is essential for analytical techniques, especially for extremely accurate systems such as supercritical fluid chromatography (SFC) coupled with high-resolution mass spectrometry (HRMS) since the limits of detections are heavily dependent on the background signal. Background: A standard option to ensure a low background signal is the usa

The study investigates the relationship between drinking water quality and birth outcomes in Colombia, focusing on early neonatal mortality and low birth weight. Using nationally representative Demographic and Health Survey data, the study combines logistic, multilevel and spatial analysis to assess individual-level and geographic determinants of neonatal health. The results show that mothers expo

The purpose of this study is to investigate the extent to which the composition of the board of directors determines directors’ remuneration in Swedish listed companies. The method approach is quantitative and deductive and a multiple linear regression model analyzes the panel data. The theoretical framework consists of previous research on board compensation and theories such as agency theory, re
