Structuring Sustainability Science

It is urgent in science and society to address climate change and other sustainability challenges such as biodiversity loss, deforestation, depletion of marine fish stocks, global ill-health, land degradation, land use change and water scarcity. Sustainability science (SS) is an attempt to bridge the natural and social sciences for seeking creative solutions to these complex challenges. In this ar

Muscle tissue saturation in humans studied with two non-invasive optical techniques; a comparative study

Muscle tissue saturation (StO(2)) has been measured with two non-invasive optical techniques and the results were compared. One of the techniques is widely used in the hospitals - the CW-NIRS technique. The other is the photon time-of-flight spectrometer (pTOFS) developed in the Group of Biophotonics, Lund University, Sweden. The wavelengths used in both the techniques are 730 nm and 810 nm. A cam

Design and Feasibility of an International Study Assessing the Prevalence of Contact Allergy to Fragrances in the General Population: The European Dermato-Epidemiology Network Fragrance Study

Background/Aims: Data on contact allergy to fragrances in the general population are limited. Data from allergological services suggest that the frequency of contact allergy to fragrances is increasing. The European Dermato-Epidemiology Network (EDEN) Fragrance Study aims to obtain reliable data on the prevalence of contact allergy to fragrances and other sensitizers of the European baseline serie

Interfacial tension and surface pressure of high density lipoprotein, low density lipoprotein, and related lipid droplets.

Lipid droplets play a central role in energy storage and metabolism on a cellular scale. Their core is comprised of hydrophobic lipids covered by a surface region consisting of amphiphilic lipids and proteins. For example, high and low density lipoproteins (HDL and LDL, respectively) are essentially lipid droplets surrounded by specific proteins, their main function being to transport cholesterol.

Loss of TFB1M results in mitochondrial dysfunction that leads to impaired insulin secretion and diabetes.

We have previously identified Transcription Factor B1 Mitochondrial (TFB1M) as a Type 2 Diabetes (T2D) risk gene, using human and mouse genetics. To further understand the function of TFB1M and how it is associated with T2D we created a β-cell specific knockout of Tfb1 m, which gradually developed diabetes. Prior to the onset of diabetes, β-Tfb1 m(-/-) mice exhibited retarded glucose clearance due

Fabrication of bottle-shaped nanochannels in fused silica using a self-closing effect

The spatial control of molecular motor function, using nanostructured surfaces, is of great interest for the development of commercial devices for diagnostics and high-throughput drug screening with molecular motors as targets. In the present study we have fabricated 100-300 nm wide nanochannels, completely subsurfaced on fused silica chips, with the aim to interface them with a microfluidic syste

Genetic association analysis of LARS2 with type 2 diabetes

LARS2 has been previously identified as a potential type 2 diabetes susceptibility gene through the low-frequency H324Q (rs71645922) variant (minor allele frequency [MAF] 3.0%). However, this association did not achieve genome-wide levels of significance. The aim of this study was to establish the true contribution of this variant and common variants in LARS2 (MAF > 5%) to type 2 diabetes risk. We

Serum from patients with systemic vasculitis induces alternatively activated macrophage M2c polarization.

Anti-neutrophil cytoplasmic antibody associated vasculitides (AAV) are conditions defined by an autoimmune small vessel inflammation. Dying neutrophils are found around the inflamed vessels and the balance between infiltrating neutrophils and macrophages is important to prevent autoimmunity. Here we investigate how sera from AAV patients may regulate macrophage polarization and function. Macrophag

Gender imbalance in a university hierarchy: can stimulus from outside prompt change?

Abstract in UndeterminedThe article draws on the reports by 12 guest professors - all women - who participated in an EU-financed pedagogical project within a Swedish university's postgraduate studies course, the purpose of which was to address equal opportunities in academia. It has been established that women with doctoral degrees are not being absorbed into the research community. The purpose of

Serum estradiol is associated with lean mass in elderly Swedish men

Objective: Association studies in men have shown that androgens are inversely related to fat measures, while the relation between sex steroids and lean mass remains unclear. We, therefore, investigated the associations between serum sex steroid levels and body composition in elderly men with a main focus on lean mass measures. Design and methods: A cross-sectional survey of a population-based coho

LES of the interaction between a premixed flame and complex turbulent swirling flow

In this paper the Triple Annular Research Swirler, a fuel injector characterized by complex design with three concentric air passages, has been studied numerically. A swirl-stabilized lean premixed flame has been simulated by means of Large Eddy Simulation. The computations characterize successfully the dynamics of the flame and their interactions with the complex swirling flow. The flame is stabi

Search for gravitational waves from binary black hole inspiral, merger, and ringdown in LIGO-Virgo data from 2009-2010

We report a search for gravitational waves from the inspiral, merger and ringdown of binary black holes (BBH) with total mass between 25 and 100 solar masses, in data taken at the LIGO and Virgo observatories between July 7, 2009 and October 20, 2010. The maximum sensitive distance of the detectors over this period for a (20, 20)M-circle dot coalescence was 300 Mpc. No gravitational wave signals w

V/P SPECT as a diagnostic tool for pregnant women with suspected pulmonary embolism.

The purpose of the study was to assess the prevalence of pulmonary embolism (PE) and other lung diseases among pregnant women with suspected PE and to calculate the radiation exposure to patient and fetus in this population. As a secondary aim, we evaluated the negative predictive value of a normal ventilation/perfusion single photon emission computed tomography (V/P SPECT) examination in pregnanc

Effects of a 3-year intervention: The Copenhagen School Child Intervention Study.

INTRODUCTION: This study assessed short and long term effects of a 3-year controlled school-based physical activity (PA) intervention on fatness, cardiorespiratory fitness (VO2peak) and cardiovascular disease (CVD) risk factors in children. METHODS: The study involved 18 schools (10 intervention and 8 controls) and included a follow-up 4 years after the end of intervention. The analyses included 6

Singular-Value Decomposition of Solution Operators to Model Evolution Equations

We consider evolution equations generated by quadratic operators admitting a decomposition in creation-annihilation operators without usual ellipticity-type hypotheses; this class includes hypocoercive model operators. We identify the singular-value decomposition of their solution operators with the evolution generated by an operator of harmonic oscillator type, and in doing so derive exact charac
