Effects of hydrogen bonding and the axial ligand interaction on the B800 band in two LH2 complexes Rhodopseudomonas (Rps.) acidophila and Rhodospirillum (Rs.) molischianum have been theo retically investigated by using density functional theory. The local electrostatic environment of the B800 bacteriochlorophyll is simulated as an atomic charge field consisting of the pigments in the protomer unit

M1 aminopeptidases comprise a large family of biologically important zinc enzymes. We show that peptide turnover by the M1 prototype, leukotriene A4 hydrolase/aminopeptidase, involves a shift in substrate position associated with exchange of zinc coordinating groups, while maintaining the overall coordination geometry. The transition state is stabilized by residues conserved among M1 members and i

The global nature of businesses has increased the geographical dispersion of operations and has made the location decision an important strategic perspective for manufacturing firms. The consensus view is that three major plant location factors must be kept in mind: (1) access to low-cost manufacturing, (2) proximity to market, and (3) access to development competences. Two options for changing th

The Sound Environment Centre at Lund University was established in March 2005. The centre is the first of its kind, both nationally and internationally. It is tasked with studying sound as a phenomenon, sound worlds and sound environments from a multi- and interdisciplinary perspective. It is a Lund University-wide body for education and research as well as external engagement in general for matte

Bakteriella infektioner är ett stort globalt hälsoproblem och mer detaljerad kunskap om värd-bakterieinteraktioner är nödvändiga för att kunna bemöta den ökande antibiotikaresistensen. Nordenfelt-labbet använder unik biosensorteknologi tillsammans med avancerad videomikroskopi och bildanalystekniker för att studera tidiga värd-bakterieinteraktioner. Den molekylära sammansättningen av bakterier ochBacterial infections represent a major global health issue and more detailed knowledge about host-bacteria interactions are needed to counteract the rising bacterial resistance to antibiotics. The Nordenfelt Lab uses unique biosensor technology in conjunction with advanced live imaging and image analysis techniques to study initial host-pathogen interactions. The molecular surface composition of

In the past two decades, the eddy covariance technique has been used for an increasing number of methane flux studies at an ecosystem scale. Previously, most of these studies used a closed path setup with a tunable diode laser spectrometer (TDL). Although this method worked well, the TDL has to be calibrated regularly and cooled with liquid nitrogen or a cryogenic system, which limits its use in r

The Amazon Basin is a unique region to study atmospheric aerosols, given their relevance for the regional hydrological cycle and the large uncertainty of their sources. Multi-year datasets are crucial when contrasting periods of natural conditions and periods influenced by anthropogenic emissions. In the wet season, biogenic sources and processes prevail, and the Amazonian atmospheric composition

Wildfires are a natural disturbance shaping boreal forests, but their effects on soil microbial communities and biogeochemical cycling remain unclear, particularly in Fennoscandia. We investigated the impact of fire severity and post-fire management on the soil microbial community two years after a boreal wildfire in Sweden. We quantified growth rates of bacteria, saprotrophic fungi (SF), ectomyco

-Reduced arterial compliance precedes changes in blood pressure, which may be mediated through alterations in vessel wall matrix composition. We investigated the effect of the collagen type I-alpha1 gene (COL1A1) +2046G>T polymorphism on arterial compliance in healthy individuals. We recruited 489 subjects (251 men and 238 women; mean age, 22.6+/-1.6 years). COL1A1 genotypes were determined using

Ligand induced activation of the beta-receptor for platelet-derived growth factor (PDGF) leads to activation of Src family tyrosine kinases. We have explored the possibility that the receptor itself is a substrate for Src. We show that Tyr934 in the kinase domain of the PDGF receptor is phosphorylated by Src. Cell lines expressing a beta-receptor mutant, in which Tyr934 was replaced with a phenyal

Background/Aims: We have observed a difference between patients on low-flux hemodialysis (HD) or peritoneal dialysis and patients on hemodiafiltration (HDF) or high-flux HD in the capacity of transmigrated leukocytes to mobilize CD11b in response to inflammatory stimuli compared with healthy subjects. This could be due to different interstitial chemokine concentrations. Methods: We measured concen

The effect of strain and transforming growth factor beta on equine tendon fibroblasts (tenocytes) was assessed in vitro. Tenocytes were isolated from flexor and extensor tendons of horses from foetal to 10 years of age. These cells were cultured until confluent on collagen-coated silicone dishes. Cyclic biaxial strain of 9 +/- 1% was applied at 0.5 Hz for 24 hours with or without added TGFbeta1 or
