- Human complex metabolic traits are in part regulated by genetic determinants. Here we applied exome sequencing to identify novel associations of coding polymorphisms at minor allele frequencies (MAFs) > 1% with common metabolic phenotypes. The study comprised three stages. We performed medium-depth (8x) whole exome sequencing in 1,000 cases with type 2 diabetes, BMI > 27.5 kg/m(2) and hypertension and in 1,000 controls (stage 1). We selected 16,192 polymorphisms nominally associated (p < 0.05) with case-control status, from four selected annotation categories or from loci reported to associate with metabolic traits. These variants were genotyped in 15,989 Danes to search for association with 12 metabolic phenotypes (stage 2). In stage 3, polymorphisms showing potential associations were genotyped in a further 63,896 Europeans. Exome sequencing identified 70,182 polymorphisms with MAF > 1%. In stage 2 we identified 51 potential associations with one or more of eight metabolic phenotypes covered by 45 unique polymorphisms. In meta-analyses of stage 2 and stage 3 results, we demonstrated robust associations for coding polymorphisms in CD300LG (fasting HDL-cholesterol: MAF 3.5%, p = 8.5 x 10(-14)), COBLL1 (type 2 diabetes: MAF 12.5%, OR 0.88, p = 1.2 x 10(-11)) and MACF1 (type 2 diabetes: MAF 23.4%, OR 1.10, p = 8.2 x 10(-10)). We applied exome sequencing as a basis for finding genetic determinants of metabolic traits and show the existence of low-frequency and common coding polymorphisms with impact on common metabolic traits. Based on our study, coding polymorphisms with MAF above 1% do not seem to have particularly high effect sizes on the measured metabolic traits.

Tidskriftsartikel (refereegranskat)abstract
- Eight European plants, used traditionally against diseases of the respiratory system, have been assayed for in vitro spasmolytic activity on guinea-pig trachea. The plants were collected or cultivated in the south of Sweden, and both water and 67% methanol extracts of the parts reported to be used in the traditional medicine were prepared and assayed. Five of the species did not show any significant activity at concentrations up to 0.6 mg extract per ml organ bath, the methanol extracts of 2 species (Glechoma hederacea and Hyssopus officinale) showed weak activity, while 0.6 mg/ml of the methanol extract of the aerial parts of Artemisia abrotanum relaxed the tone induced by 0.1 μmol/l carbachol almost (80%) as effectively as 2.2 mmol/l terbutaline.

Structure-activity relationships for unsaturated dialdehydes 8( *). Comparative effects of 10 sesquiterpenoids on the sea urchin gamete fertilization.
- 1993

Tidskriftsartikel (refereegranskat)abstract
- The effects of 10 sesquiterpenoids with unsaturated dialdehyde functionalities were studied on fertilization, first cleavage, and calcium permeability of egg membranes of sea urchin gametes. Fertilization was inhibited by nine compounds when sperm was exposed and by five compounds when eggs were exposed (50 mug/ml for 5 min). All compounds except one (9alpha-hydroxymerulidial) inhibited the first cleavage in a dose-response manner. Only one compound (velleral) increased the Ca(2+) permeability of egg membranes at 20 mug/ml. All compounds reduced to a varying extent the ATP-driven Ca(2+) sequestration by non-mitochondrial intracellular compartments. In general, when hydroxylated and non-hydroxylated derivatives of the compounds are compared, the hydroxylated ones present a lower toxicity when measuring fertilization and cleavage inhibition, and reduction of intracellular Ca(2+) sequestration.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- An empirical study of energy use in the residential sector of the five biggest EU countries by population (France, Germany, Italy, Spain, UK) and Sweden from 1990 to 2015 has been carried out to determine the impact that efficiency policies have had. Preliminary results have isolated the effects of (i) energy efficiency focused building codes and (ii) general efficiency policies, and have found that both have had a significant impact on reducing energy demand. A model has been created that will allow further exploration of policies specifically related to the EU Energy Performance of Buildings Directive (EPBD).

Saving energy in residential buildings: the role of energy pricing

- A zero-carbon society requires dramatic change everywhere including in buildings, a large and politically sensitive sector. Technical possibilities exist but implementation is slow. Policies include many hard-to-evaluate regulations and may suffer from rebound mechanisms. We use dynamic econometric analysis of European macro data for the period 1990–2018 to systematically examine the importance of changes in energy prices and income on residential energy demand. We find a long-run price elasticity of −0.5. The total long-run income elasticity is around 0.9, but if we control for the increase in income that goes towards larger homes and other factors, the income elasticity is 0.2. These findings have practical implications for climate policy and the EU buildings and energy policy framework.

The effect of six sesquiterpenoid unsaturated dialdehydes on cell membrane permeability in human neuroblastoma SH-SY5Y cells.

Tidskriftsartikel (refereegranskat)abstract
- The effect of six sesquiterpenes containing an unsaturated dialdehyde functionality, on cell membrane permeability in the human neuroblastoma cell line SH-SY5Y has been studied. The kinetics of the membrane leakage after addition of the sesquiterpenes were determined by measuring the efflux of radioactivity from cells preloaded with tritiated 2-deoxyglucose. The concentrations that gave 5% and 20% efflux of radioactivity as compared with control cells (EC5 and EC20) were determined for each compound. In spite of the structural similarities between the compounds, the effects on cell membrane permeability varied considerably. EC20 for polygodial, which is the most active compound, is 2.5 microM after 20-min incubation, but no leakage could be determined for merulidial even at concentrations as high as 4 mM. Rather, this compound seems to stabilize or fix the cell membrane and a lower efflux of radioactivity was observed as compared to the control cells. A quantitative structure-activity relationship analysis for the five active compounds showed a good correlation between the membrane leakage activity and certain chemical characteristics. Structural features strongly correlated with high activity were found to be: The geometry and the atomic charges of the unsaturated dialdehyde functionality, the dipole moment, the energy difference between the lowest unoccupied molecular orbital and the highest occupied molecular orbital and the lipophilicity.

- IntroductionSex differences in dementia risk, and risk factor (RF) associations with dementia, remain uncertain across diverse ethno-regional groups. MethodsA total of 29,850 participants (58% women) from 21 cohorts across six continents were included in an individual participant data meta-analysis. Sex-specific hazard ratios (HRs), and women-to-men ratio of hazard ratios (RHRs) for associations between RFs and all-cause dementia were derived from mixed-effect Cox models. ResultsIncident dementia occurred in 2089 (66% women) participants over 4.6 years (median). Women had higher dementia risk (HR, 1.12 [1.02, 1.23]) than men, particularly in low- and lower-middle-income economies. Associations between longer education and former alcohol use with dementia risk (RHR, 1.01 [1.00, 1.03] per year, and 0.55 [0.38, 0.79], respectively) were stronger for men than women; otherwise, there were no discernible sex differences in other RFs. DiscussionDementia risk was higher in women than men, with possible variations by country-level income settings, but most RFs appear to work similarly in women and men.

Tidskriftsartikel (refereegranskat)abstract
- From an extract of the roots of Cadaba natalensis Sond. the novel macrocyclic dibenzo-diazacyclododecanedione 1 was isolated together with (S)-2-ethyl-2-methyloxazolidin-5-one (2a). In addition, the five known compounds were obtained. Of these, (R)-5-ethyl-5-methyloxazolidin-2-one (3) is reported as a natural product for the first time. The structures of the isolated compounds were elucidated by analysis of the spectral data, 1D NMR (1H, 13C, and DEPT), 2D NMR (COSY, HMQC, HMBC, and NOESY), and HRESIMS, as well as by the comparison with previously reported data.
