BCS1L is a chaperone necessary for the incorporation of Rieske Fes and Qcr10p into complex III (CIII) of the respiratory chain. Mutations in the BCS1L gene cause early fetal growth restriction and a lethal neonatal disease in humans, however, the pathogenesis remains unclear. Here, we analysed the expression of BCS1L during mouse embryonic development and compared its expression with that of the m

Interactions between two ectomycorrhizal fungal species, Piloderma croceum Erikss. and Hjortst. and Piloderma sp. 1 (found to colonise spruce roots and wood ash granules in the field), were investigated in wood ash amended substrates. The comparative ability of these fungi to colonise roots of non-mycorrhizal spruce (Picea abies (L.) Karst.) seedlings was studied in relation to factorial combinati

Beside agricultural soils, tropical rainforest soils are the main source of atmospheric N2O. Current estimates of the global N2O source strength of tropical rainforest soils are still based on rather simplistic upscaling approaches and do have a large range of uncertainty. In this study, the biogeochemical ForestDNDC-tropica model was recalibrated and intensively tested on the site scale prior to

Department of Occupational and Environmental Medicine, Institute of Laboratory Medicine, Lund University Hospital, S-221 85 Lund, Sweden. The aim of this study was to investigate if the uptake of N-methyl-2-pyrrolidone (NMP), a widely used industrial chemical, increases after exposure to NMP in humid air compared to dry air. NMP has been described to be an airway irritant and a developmentally to

Popular Abstract in Swedish Lignin är ett biobränsle som kan extraheras från sulfatmassaindustrins koklutar (svartlut). Lignin kan även användas som specialkemikalie. Massaindustrin har därmed tillgång till en än så länge outnyttjad källa för inkomster. Dessutom kan ligninuttag leda till processförbättringar under kokning och blekning av pappersmassan. I det här arbetet har ligninuttag med keramiLignin is a potential biofuel which can be extracted from kraft cooking liquor. Lignin can also prove valuable as a speciality chemical. By extracting lignin potential economical revenue can be gained by pulp mills, as well as technical benefits such as easier delignification and bleaching. The subject of this work was the extraction of lignin from kraft cooking liquor using ceramic ultrafiltrati

Lactobacillus acidophilus DSM 20079 is the producer of a novel bacteriocin termed acidocin D20079. In this paper, mode of action using three various concentrations of acidocin D20079 (2,048, 128 and 11.3 AU/ml) was determined against an indicator strain L. delbrueckii subsp. lactis DSM 20076. These concentrations all led to marked decreases in both the number of viable cells and in optical density

Three fragrances, limonene, benzaldehyde, and phenethylalcohol (that differ in their polarities), were solubilized in hexagonal liquid crystal using the polyethylene oxide-polypropylene oxide-polyethylene oxide, (EO27 PO61 EO27), P-104 triblock copolymer, and water. The interlayer spacing of the hexagonal liquid crystals were established using small-angle x-ray scattering (SAXS). The SAXS data are

Hematopoietic stem cells (HSCs) are defined by their unique properties to self-renew and differentiate into all hematopoietic cell lineages. Residing in the bone marrow (BM), adult HSCs are organized in a hierarchy of cells that differ in their self-renewal and proliferative capacity. Exact relationships of the various cells in the hematopoietic hierarchy, their potential to commit to certain line

The aim of the present study was to investigate the pharmacodynamics of moxifloxacin against strains of Streptococcus pyogenes with different susceptibilities to erythromycin by using an in vitro kinetic model simulating human pharmacokinetics of moxifloxacin at oral doses of 400 and 200 mg, respectively. When the different strains of S. pyogenes were exposed to the higher dose, the number of bact

Hemolytic uremic syndrome (HUS) includes a heterogeneous group of hemolytic disorders. Among the identified causes of HUS are infections, particularly infections with Shiga toxin-producing ESCHERICHIA COLI (STEC), complement disorders, and disorders interfering with the degradation of von Willebrand factor (VWF). Other causes for atypical HUS include the cobalamin metabolism; pregnancy/hemolysis,

Popular Abstract in Swedish Den senglaciala och Holocena strandförskjutningen i Östersjön har sin grund i samspelet mellan den isostatiska landhöjningen och den eustatiska havsyteförändringen, vilka är orsakade av den senaste inlandsisens tillväxt och avsmältning. Detta samspel ledde till relativa förändringar av vattenytan i världshaven och har medfört att den nuvarande Östersjön tidvis varit isoLateglacial and Holocene shoreline displacement along the Baltic coast resulted from both the isostatic land uplift and the ice-volume-equivalent sea-level rise. Relative changes of these two components led to alternating contact/isolation of the Baltic Basin with the North Sea during the Holocene. The Littorina transgression was a significant palaeoceanographic change that took place during the m
