The kinetics of kraft lignin (KL) aggregation at alkaline conditions was studied by quasi-elastic light scattering (QELS) and turbidity measurements. Stability ratios (W) for HL were obtained at 70 degreesC and various concentrations of sodium chloride. By analyzing the early-time evolution data of aggregate growth obtained from QELS, fractal dimensions of flocs formed in both reaction-limited clu
Bacterial vaginosis is a change in flora, the cause of which is still unknown in the vast majority of instances. Bacterial vaginosis has generally been used to represent any change in vaginal flora resulting in an assumed loss of lactobacilli. However, whether such a flora represents the genetically normal state of some women is poorly defined. The present 'crude' diagnosis of bacterial vaginosis
BACKGROUND: From the viewpoint of the clinical neuropsychologist, it is not evident if the detection of solvent induced toxic encephalopathy (TE) could be optimized by a modification of the traditional test batteries, adding tests covering new dimensions or monitoring further functional domains. METHODS: To clarify this issue, TE patients were re-examined with (a) the tests traditionally used in s
Osmoderma eremita is a threatened scarab beetle living in the hollows of old deciduous trees and is regarded as an umbrella species of the beetle fauna associated with this habitat. Several methods like pitfall trapping and wood mould sampling have been used to monitor the occurrence of O. eremita, but these methods cannot be applied for trees with certain characteristics. Recently, (R)-(+)--decal
The hypothalamus is the main appetite-regulating center in the brain receiving peripheral signals regarding the metabolic status of the body. Pancreatic procolipase has recently been identified in rat hypothalamus. Procolipase is known mainly for its actions in the intestine where it is cleaved to colipase, an enzyme required for the maintenance of pancreatic lipase activity, and enterostatin, a p
Human gliomas express TGF-beta but, so far the expression of downstream mediators has been investigated in only a few cell lines. We have examined tissue specimens of 23 gliomas: 3 astrocytomas grade II (AST), 8 anaplastic astrocytomas grade III (AAST), and 12 glioblastoma multiforme grade IV (GBM). We analyzed the mRNA expression of TGF-beta1, TGF-beta2, TGF-beta3, the TGF-beta receptors type I (
På socionomutbildningarna i Norden skall studenterna både praktiskt och teoretiskt lära sig socialt arbete. I artikeln redovisas resultat från en undersökning av vilket teoretiskt innehåll socionomutbildningarna lägger i ämnet, hur det integreras i utbildningen och vem som undervisar i ämnet.
A testicular form of hormone-sensitive lipase (HSLtes), a triacylglycerol lipase, and cholesterol esterase, is expressed in male germ cells. Northern blot analysis showed HSLtes mRNA expression in early spermatids. Immunolocalization of the protein in human and rodent seminiferous tubules indicated that the highest level of expression occurred in elongated spermatids. We have previously shown that
PURPOSE: This study was designed to investigate, in a population-based setting, the surgical outcome in patients with rectal cancer according to the hospital volume. METHODS: Since 1995 all patients with rectal cancer have been registered in the Swedish Rectal Cancer Registry. Hospitals were classified, according to number treated per year, as low-volume, intermediate-volume, or high-volume hospit
Peatlands are important ecosystems in the context of biospheric feedback to climate change, due to the large storage of organic C in peatland soils. Nitrogen deposition and increased nutrient availability in soils following climate warming may cause changes in these ecosystems affecting greenhouse gas exchange. We have conducted an N and P fertilization experiment in two Swedish bogs subjected to
With the aim to characterize patterns in toxicological profile and manner of death in deceased users of anabolic androgenic steroids (AAS), a retrospective autopsy protocol study of 52 deceased users of AAS was undertaken. The AAS users were compared to 68 deceased users of amphetamine and/or heroin who were consecutively tested and found to be negative for AAS. Use of AAS was in the majority of c
Chronic or repeated stress during critical periods of human fetal brain development has been associated with various learning, behavioral and/or mood disorders in later life. In this investigation, pregnant Fischer 344 rats was individually restrained three times a day for 45 min during the last week of gestation in transparent plastic cylinders while at the same time being exposed to bright light
Objective: To evaluate the reproducibility of fetal heart rate (FHR) baseline estimation according to an objective and detailed definition presented in this article, by comparison with the FIGO guidelines' definition. Study design: Three hundred consecutively acquired FHR tracings, 150 from antepartum high-risk pregnancies and 150 from unselected intrapartum cases, were presented to nine experienc
Genetic factors influence susceptibility to multiple sclerosis but the responsible genes remain largely undefined, association with MHC class II alleles being the only established genetic feature of the disease. The Nordic countries have a high prevalence of multiple sclerosis, and to further explore the genetic background of the disease, we have carried out a genome-wide screen for linkage in 136
The present study investigated effects of short-term administration of adrenocorticotrophic hormone (ACTH) on blood lipid profile and renal function in kidney transplant patients. Six patients who had kidney transplantations 2 to 10 years earlier received ACTH intramuscularly (1 mg/d) for 4 days. We analyzed serum levels of lipids, lipoproteins, apolipoproteins, blood creatinine, and other paramet
