Digestion of sludge and organic waste in the sustainability concept for Malmo, Sweden

Anaerobic digestion of sludge has been part of the treatment plant in Malmo for many years and several projects on optimisation of the digestion process have been undertaken in full scale as well as in pilot scale. In order to facilitate a more sustainable solution in the future for waste management,solid waste organic waste is sorted out from households for anaerobic treatment in a newly built ci

Expression, purification and characterisation of a Bacillus subtilis ferredoxin: a potential electron transfer donor to cytochrome P450 BioI

The fer gene from Bacillus subtilis has been subcloned and overexpressed in Escherichia coli and the protein (Fer) purified to homogeneity. N-Terminal sequencing and mass spectrometry indicate that the initiator methionine is removed from the protein and that the molecular mass is 8732 Da consistent with that deduced from the gene sequence. Amino-acid sequence comparisons indicate that Fer is a fe

Calpain activation and apoptosis in motor neurons of cultured adult mouse spinal cord

Calpain, a Ca2+-dependent cysteine protease, has been implicated in neuronal apoptosis following spinal cord injury. In this study, activation of calpain was investigated in motor neurons of adult spinal cord slices from the mouse, using a cell-permeable fluorogenic calpain substrate and Western blotting. Calpain was rapidly activated in the motor neurons of excised spinal cord slices and calpain

Sigmoidins J and K, two new prenylated isoflavonoids from Erythrina sigmoidea

In addition to the two known compounds neotautenol [2] and erythrinassinate B [4], two new compounds, an isoflavanone named sigmoidin J [1] and a coumestan derivative named sigmoidin K [3], have been isolated and characterized from the root bark of the Cameroonian medicinal plant Erythrina sigmoidea. Their structures have been established as 7, 4'-dihydroxy-2',5'-dimethoxy-6'(gamma, gamma-dimethyl

Vertical, monovocalic and other impossible vowel systems: a review of the articulation of the Kabardian vowels.

The North West Caucasian language Kabardian has a minimal vowel system, the analysis of which has engendered significant controversy. Phonetically, Kabardian is interesting for the extensive assimilation of its few vowel phonemes to the surrounding consonants. Two published descriptions of these assimilations by J. C. Catford ("The Kabardian Language," Maitre Phonetique, 3rd series, 1942, 77, 15-1

Does stage at diagnosis explain the difference in survival after breast cancer in Denmark and Sweden?

Breast cancer survival differs 9 percentage points between the neighbouring countries of Denmark and Sweden. The authors' aim was to analyse whether this was caused by early detection in Sweden. The extent of disease and outcome was compared in two population-based breast cancer cohorts in 1983-1989. Breast cancer management was decentralized in Denmark without mammography screening whereas treatm

Comparison of the PKCalpha and the PKCepsilon C1b Domains: Identification of Residues Critical for PKCepsilon-mediated Neurite Induction.

We showed earlier that over-expression of protein kinase C (PKC) epsilon induces neurite outgrowth. The effect is mediated by a region (PKC epsilon PSC1V3) encompassing the pseudosubstrate, the two C1 domains and part of the V3 region, and is independent of the catalytic activity of the enzyme. In this region, residues immediately N-terminal of the C1b domain are crucial for neurite outgrowth. How

COHb% as a marker of cardiovascular risk in never smokers: results from a population-based cohort study.

Aim: Carbon monoxide (CO) in blood as assessed by the COHb% is a marker of the cardiovascular ( CV) risk in smokers. Non-smokers exposed to tobacco smoke similarly inhale and absorb CO. The objective in this population-based cohort study has been to describe inter-individual differences in COHb% in never smokers and to estimate the associated cardiovascular risk. Methods: Of the 8,333 men, aged 34

Role of stray light in the formation of high-resolution resonant photoelectron spectra: an experimental and theoretical study of N-2

We show that the undular stray light, diffusely scattered by the optical system of a synchrotron beamline, can play an important role in the formation of high-resolution resonant photoelectron (RPE) spectra. The influence of the stray light is mediated through the Stokes doubling effect, with the Lorentzian tail of the spectral function being replaced by a more complicated form. This effect is sho

Electroanalytical study of Prussian Blue modified glassy carbon paste electrodes

Two types of glassy carbon (GC) powder (i.e., Sigradur K and Sigradur G) have been mixed with mineral oil to obtain glassy carbon paste electrodes (GCPE's). The electrochemical behavior of such electrodes at different percentages of glassy carbon has been evaluated with respect to the electrochemistry of ferricyanide as revealed with cyclic voltammetry and the best paste composition was chosen. GC

Fertilitetsbevarande kirurgi vid livmoderhalscancer nu möjlig

This article describes the first Swedish experience with fertility preserving surgery according to the technique of Dargent. Minimally invasive methods gain acceptance in the treatment of other tumours and this method seems to treat adequately and preserve function. The literature is reviewed and discussed. In Sweden about 25-40 women under 30 years of age are each year diagnosed with cancer of th

Broad spectrum of time of detection, primary symptoms and disease progression in infants with HIV-1 infection

The relationship between time of HIV-1 detection, appearance of symptoms and disease progression was studied in all 24 HIV-1-infected infants from a cohort of 117 children who were born to HIV-1-infected mothers and monitored from birth. HIV isolation from plasma and mononuclear cells, HIV-1 DNA PCR (polymerase chain reaction) and, retrospectively, a quantitative assay for HIV-1 RNA were used for

Cartilage proteins and their arthritogenic properties in arthritis

Popular Abstract in Swedish I denna avhandling behandlas brosk proteiners roll såsom antigen och tillgänglighet av immunsystemet i artrit. Sex artiklar omfattas, där fyra presenterar nya djur modeller för reumatoid artrit (RA), en visar hur en genetisk störning av ett broskprotein kan förvärra artrit och den sista hur posttransnationell modifiering av kollagen typ II (CII) påverkar T-cells toleranIn this thesis the role of cartilage proteins and their potential as antigen and availability to the immune system in arthritis were investigated. Six papers are included; where four present new animal models for Rheumatoid arthritis (RA), one shows how genetic disorders in cartilage may affect arthritis and the last how posttranslational modification of collagen type II (CII) affects tolerance.
