Pre-treatment of sisal pulp prior to its anaerobic digestion was investigated using an activated sludge mixed culture under aerobic conditions in batch bioreactors at 37 degrees C. The progression of aerobic pre-treatment of the residue in relation to the activities of some extracellular hydrolytic enzymes in the slurry was monitored. The highest activity of hydrolytic enzymes was obtained at 9 h
Responses to isotonic quick releases of rabbit urinary bladder strips and rat portal veins activated by AC-stimulation and K+-high medium were studied. The AC stimulation was adjusted to give the same tension as th K+-contractures. Releases were performed at peak of the contractions (which was attained after 1.5-4.5 s AC-stimulation or 2-3 min in K+-high solution). The length response consisted of
Background: Retinoids are vital for embryonic development; both excesses and deficiencies of vitamin A are known to give similar patterns of birth defects. Concentrations of retinol in newborns and in pregnant women have been investigated, but concentrations of the biologically active metabolite all-trans retinoic acid and its isomer 13-cis retinoic acid have not. Objective: We measured serum conc
Background: Relapse of hepatitis C virus (HCV) infection after liver transplantation (LT) is universal. Tolerance for treatment with pegylated-interferon (peg-IFN) and ribavirin (RBV) is suboptimal and withdrawals due to adverse events frequent. We sought to improve tolerance for treatment to improve outcome. Methods: We used concentration-guided RBV dosing to achieve an intended 10 mu mol/L conce
In this study we have investigated whether the carbon isotopic signature differs between different groups and species of marine phytoplankton depending on growth phase, nutrient conditions and salinity. The 15 investigated algal species, representing the Bacillariophyceae, Chlorophyceae, Cryptophyceae, Cyanophyceae, Dinophyceae and Haptophyceae classes were grown in batch monocultures and analysed
Aim: To investigate the therapeutic effects of fluorouracil (5-Fu) and octreotide (Oct) continuous regional arterial infusion (CRAI,) alone or in combination, was administered in a canine model of severe acute pancreatitis (SAP). Materials and Methods: The animals were divided into five groups; group A (Sham), group B (SAP), group C (SAP and 5-Fu), group D (SAP and Oct), and group E (SAP and 5-Fu
Purpose: To investigate the use of different modes of transport and long-term changes among stroke survivors with cognitive functional limitations (CFLs), and to study differences among sub-groups (decreased/ceased vs. unchanged and increased public transport use) regarding physical functional limitations (PFLs), CFLs, depression, and social activity outside home. Method: Survey of 79 individuals
Aim: The purpose of this study was to investigate the relationship between maximum oxygen uptake (VO2PEAK) and body fat in young children on a population-based level. Methods: Participants were 586 children (311 boys and 275 girls) aged 6.8 +/- 0.4 years, recruited from a population-based cohort. VO2PEAK was measured by indirect calorimetry during a maximal exercise test. Percent body fat (BF%) wa
A cochlear implant (CI) is a device that provides individuals with severe to profound hearing impairment (SPHI) with auditory stimulation, which makes it possible for them to develop skills related to spoken communication. We have little knowledge about how hearing with a CI influences cognitive and communicative development and there is a need for development of methods for assessment. The genera
Popular Abstract in Swedish När Immanuel Kant år 1795 lät publicera sin lilla skrift Om den eviga freden väckte den stor uppmärksamhet över hela Europa och översattes snart till flera språk. Hur kom det sig att den i samband med tvåhundraårsjubileet 1995 åter var så populär att flera av världens tongivande filosofer diskuterade den och skrev artiklar om den? Nutida tänkare lockas dock av andra idéThis dissertation, a contribution to the history of ideas, is a study of Immanuel Kant’s 1795 monograph Zum ewigen Frieden (Perpetual Peace) and its effective history. The intention is to show how this particular work has been formed, read, discussed and interpreted for about 200 years. Considering the attention the work received on its bicentennial anniversary in comparison with the attention it
Background:To evaluate the relationships between postnatal change in circulatory insulin-like growth factor I (IGF-I) concentrations, brain volumes, and developmental outcome at 2 years of age in very preterm infants.Methods:IGF-I was measured weekly and nutritional intake was calculated daily from birth until a postmenstrual age (PMA) of 35 weeks. Individual beta coefficients for IGF-I, IGF-I(B)
Many individuals treated for depression suffer relapse or recurrence after treatment. Known risk factors include number of previous depressive episodes and residual symptoms after treatment. Both relapse/recurrence rates and predictors of relapse/recurrence, however, may differ between various settings. To perform a naturalistic evaluation of the sustained effectiveness of treatment for adult clin
Following the development of large-scale use of biomass energy in the EU, international biofuel trade is a plausible scenario and something that is already taking place in Northern Europe. This paper focuses on Swedish biofuel imports, both direct and indirect imports, the latter which derive from the fact that part of the imported pulpwood and timber end up as fuel. The objective is to describe t
We investigated the role of blood components in the adhesion of staphylococci to biological and artificial surfaces under well-defined flow conditions by using the Cone and Plate(let) Analyzer. An enzyme-linked immunosorbent assay-like binding assay with biotinylated bacteria determined the extent of bacterial adhesion to subendothelial extracellular matrix (ECM), polystyrene (PS) and adult bovine
Background-Leukocyte concentration in blood is a classical marker of systemic inflammation. Whether high leukocyte counts are associated with incidence of heart failure (HF) is unknown. This population-based study explored whether the leukocyte concentrations were associated with incidence of hospitalizations due to HF. Methods and results-Leukocyte counts were measured in 16 940 men from the gene
The thermoresponsive copolymer of N-isopropylacrylamide (NIPAM) with 1-vinylimidazole (VI), poly(NIPAM-VI), synthesized by radical polymerization has been used to purify the histidine-tagged green flourescent protein (His-tag GFP) from recombinant E. coli by metal-chelate affinity precipitation. The purified protein was immobilized on the BIAcore sensor chip by carbodiimide coupling. Affinity bind
Objectives: To compare the cost-effectiveness of the treatment of ankylosing spondylitis (AS) with infliximab in the United Kingdom over lifetime estimated from two different clinical trials and adjusted for clinical practice guidelines. Methods: A cost-effectiveness model was developed to incorporate clinical, epidemiological, and economic data and allow extrapolation of trial results and incorpo
Human galectins have functionally divergent roles, although most of the members of the galectin family bind weakly to the simple disaccharide lactose (Galss1-4Glc). To assess galectin-glycan interactions in more detail, we explored the binding of several important galectins (Gal-1, Gal-2, and Gal-3) on a glycan microarray containing hundreds of structurally diverse glycans. All three galectins exh
