For the period 1420-1960 we contrasted fire events reconstructed at 14 sites distributed over a 50 km x 50 km area in the central part of the Komi Republic (European Russia) with a set of tree-ring width chronologies of Scots pine (Pinus sylvestris L.), developed for the same area. Our aim was to infer common climatic information contained in treering variables and independently dated fire events
ydrophobically modified polymers (HM-P) typically behave as thickeners in a wide range of systems. The thickening effect in an aqueous solution of this kind of polymer depends on intermolecular hydrophobic associations and also on chain entanglements if the polymer concentration is significantly above the overlap concentration. In the present investigation a rather short end-capped polymer has bee
The sensitivity of the rat submaxillary gland was examined 3-4 weeks after either parasympathetic decentralization or sympathetic decentralization or denervation. The threshold doses for secretion of saliva of parasympathomimetic (methacholine) and sympathomimetic (noradrenaline, adrenaline, phenylephrine and isoprenaline) drugs were estimated and the amount of saliva secreted in response to supra
Context: T-3 action in neurons is essential for brain development. Recent evidence indicates that monocarboxylate transporter 8 (MCT8) is important for neuronal T-3 uptake. Hemizygous mutations have been identified in the X-linked MCT8 gene in boys with severe psychomotor retardation and elevated serum T-3 levels. Objective: The objective of this study was to determine the functional consequences
Popular Abstract in Swedish Fetma räknas som ett av världens tio viktigaste hälsoproblem enligt WHO och ökar i snabb takt. Man beräknar att över 1 miljard av världens vuxna befolkning är överviktig, d.v.s. har ett kroppsmasseindex (BMI) ?25.0 kg/m², varav 300 miljoner är feta, d.v.s. har ett BMI ?30.0 kg/m². I Sverige är 38% av kvinnor och 58% av män mellan 25 och 64 år överviktiga, och 11% respekThe aim of this thesis was to study the morbidity and mortality of cardiovascular disease (CVD) in obese individuals, as measured by different obesity measurements, and to explore how the CVD risk related to obesity was modified by other biologic and socio-demographic circumstances. Data from two population-based cohort studies was used. The Malmö Preventive Project included 22 444 middle-aged me
The presence of polyamines in living cells is crucial for survival. Due to their high net charge at physiological pH, polyamines effectively charge neutralize the phosphodiester backbone of DNA in an interaction that also may protect the DNA from external damage. We here present a study illustrating the influence of spermidine and spermine on the platination reactions of the model oligonucleotides
Objective Cognitive dysfunction is common in multiple sclerosis (MS), but long-term data on cognition in patients with clinically isolated syndromes are sparse. Methods We determined cognitive functions in 22 patients 44-75 years old diagnosed with optic neuritis 24-31 years earlier but had no further clinical bouts and had not progressed clinically to MS. We used a neuropsychological test battery
The marketplace for probiotic foods is burgeoning, measured in billions of euro per annum. It is imperative, however, that all bacterial strains are fully assessed for human safety. The ability to bind fibrinogen is considered a potential pathogenicity trait that can lead to platelet aggregation, serious medical complications, and in some instances, death. Here we examined strains from species fre
PURPOSE: Although survival has been studied for various subtypes of non-Hodgkin's lymphoma (NHL), there have been few comprehensive studies to quantify the prognosis, including all specific histologies. The effect of family history on survival in NHL has not been examined. METHODS: We used the Swedish Family-Cancer Database to estimate hazard ratios in NHL by histology and family history. RESULTS:
OBJECTIVE: The aim of this study was to investigate the effect of epidermal growth factor receptor (EGFR) blockade on cell survival and on downstream signalling pathways using the monoclonal antibody cetuximab. METHODS: We used three colon cancer cell lines, of which one was EGFR-negative, and two head and neck squamous cell carcinoma (HNSCC) lines. EGFR expression and gene copy number were measur
Secretion of mucins and exudation of plasma are distinct processes of importance to innate immunity and inflammatory disease. Yet, little is known about their relation in human airways. The objective of the present study was to use the human nasal airway to determine mucinous secretion and plasma exudation in response to common challenge agents and mediators. Ten healthy volunteers were subjected
OBJECTIVE: To investigate how well short-term progression rates can predict long-term visual field outcomes in patients with glaucoma. METHODS: We calculated visual field rates of progression using linear regression analysis of the Visual Field Index (VFI) for 100 consecutive patients with glaucoma having 10 or more Swedish Interactive Thresholding Algorithm standard field tests. Final VFI was pre
BACKGROUND: For unknown reasons girls are at an increased risk of coeliac disease compared to boys. However, the observed association might be confounded, since maternal coeliac disease is associated with both an increased risk of the disease in first-degree relatives as well as an increased ratio of girls to boys in offspring. AIMS: We investigate the effect of sex on the risk of coeliac dise
Little information is available on the effect of neighborhood deprivation on mortality in individuals with cancer. The aim of this study was to investigate the effect of level of neighborhood deprivation on mortality after a wide range of cancer diagnoses. This 1990-2004 follow-up study included all individuals in Sweden aged 25-74 years and used multilevel logistic regression with individual-leve
A defective form of the AIRE protein causes autoimmune destruction of target organs by disturbing the immunological tolerance of patients with a rare monogenic disease, autoimmune polyendocrinopathy (APE)-candidiasis (C)-ectodermal dystrophy (ED), APECED. Recently, experiments on knockout mice revealed that AIRE controls autoimmunity by regulating the transcription of peripheral tissue-restricted
AIM: Mortality after curative surgery for rectal cancer is increased if surgery is not performed within a week of completed short course radiotherapy. A link to the suppression of leucocytes after neoadjuvant radiotherapy has been suggested. This study investigates the effects of radiotherapy on peripheral leucocyte counts, complications and survival. METHOD: Patient data variables from a retrospe
Alterations in the expression and signalling pathways of vascular endothelial growth factor (VEGF) have been linked to the clinical features and pathogenesis of hematologic malignancies. In this study, we showed that VEGF protein expression was statistically significantly higher in the leukemic blasts than in the normal hematopoietic counterparts. A statistically significant correlation between ex
The retinoblastoma (pRb)-related p130 pocket protein is a regulator of cell growth and differentiation, and a candidate tumour suppressor. Both pRb and p130 operate through interactions with cellular proteins, including the E2F transcription factors. While such interactions are controlled by phosphorylation of multiple sites of pRb, regulation of p130 remains poorly understood. We now identify 22
The present study investigated whether the rotation rate induced by amphetamine in 6-OHDA-lesioned rats was predictive of development of l-DOPA-induced dyskinesia (LID) and success of the lesion procedure in our experimental settings. We collected data from 312 6-OHDA-lesioned rats (from different sets of experiments). Rats were subjected to the amphetamine-induced rotation test (2.5mg/kg) and chr
Efficient and suitable daily landfill cover is considered the most important aspect for minimising the negative impact of landfills on the local environment and population, especially in arid and semiarid countries. In this study, numerical model, HYDRUS-2D/3D, was used to investigate the impact of landfill cover type, cover thickness and antecedent water content on the quantity and the rate of co
