- Data on macrofungal diversity and distribution patterns were compiled for major geographical regions of the world. Macrofungi are defined here to include ascomycetes and basidiomycetes with large, easily observed spore-bearing structures that form above or below ground. Each coauthor either provided data on a particular taxonomic group of macrofungi or information on the macrofungi of a specific geographic area. We then employed a meta-analysis to investigate species overlaps between areas, levels of endemism, centers of diversity, and estimated percent of species known for each taxonomic group for each geographic area and for the combined macrofungal data set. Thus, the study provides both a meta-analysis of current data and a gap assessment to help identify research needs. In all, 21,679 names of macrofungi were compiled. The percentage of unique names for each region ranged from 37% for temperate Asia to 72% for Australasia. Approximately 35,000 macrofungal species were estimated to be "unknown" by the contributing authors. This would give an estimated total of 56,679 macrofungi. Our compiled species list does not include data from most of S.E. Europe, Africa, western Asia, or tropical eastern Asia. Even so, combining our list of names with the estimates from contributing authors is in line with our calculated estimate of between 53,000 and 110,000 macrofungal species derived using plant/macrofungal species ratio data. The estimates developed in this study are consistent with a hypothesis of high overall fungal species diversity.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Limited comparative studies assessing the health-related quality of life (HRQL) in heart failure (HF) patients with preserved vs. low ejection fraction (LVEF) have been disparate. AIMS: The aims of this study were a) to characterize HRQL in a large population of HF patients with preserved and low LVEF and b) to determine the factors associated with worse HRQL. METHODS: Patients with symptomatic HF (NYHA Class II-IV) enrolled in the Candesartan in Heart Failure: Assessment of Reduction in Mortality and Morbidity (CHARM) HRQL study completed the Minnesota Living with Heart Failure questionnaire at randomization. Patients were stratified into 2 HF cohorts: preserved LVEF (>40%) and low LVEF (

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Lipid lateral segregation in biomimicking model membranes has recently become a topic of great interest due to the biological coupling to the concept of functional rafts. In the studies of liquid-liquid phase coexistence it is found that lateral phase separation into liquid ordered and liquid disordered phases takes place in ternary systems consisting of one unsaturated and one saturated lipid, together with a sterol. The phase behavior is critically dependent on the components with respect to chain length, degree of unsaturation and sterol structure and the driving force of the phase separation is closely related to the ordering effect of the sterol on the lipid chains. This study presents NMR data for binary and ternary systems composed of mixtures of sphingomyelins, phosphatidylcholines and cholesterol. Order parameters were obtained from perdeuterated chains in the saturated lipid and diffusion data of both the saturated and unsaturated lipids were measured with the pulsed field gradient NMR method. Data were analyzed with regard to phase separation into liquid and solid phases.

Tidskriftsartikel (refereegranskat)abstract
- A simple and easy-to-use extraction method for aqueous samples based on hollow fibre-supported liquid membrane (HF-SLM) followed by liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) was developed to determine ivermectin and transformation products, the monosaccharide (TP1) and the aglycon of ivermectin (TP2). The proposed method attained enrichment factors up to 80, after optimising parameters, such as fibre length, organic solvent, stirring speed, salt level, pH in samples/fibre, extraction time and fibre emptying technique. Method validation with tap and lake water samples provided good linearity and detection limits of 0.2, 1.6 and 0.9 mu g/l for ivermectin, TP1 and TP2 in lake water with RSD below 15%.
