Using glacial rebound models we have inverted observations of crustal rebound and shoreline locations to estimate the ice thickness for the major glaciations over northern Eurasia and to predict the palaeo-topography from late MIS-6 ( the Late Saalian at c. 140 kyr BP) to MIS-4e ( early Middle Weichselian at c. 64 kyr BP). During the Late Saalian, the ice extended across northern Europe and Russia

Purpose: To evaluate changes in distribution of hepatic arterial blood flow in the liver following insertion of an uncovered stent and subsequently a stent-graft in the trans-jugular intrahepatic portosystemic shunt (TIPS) channel. Methods: The experiments were performed in eight healthy pigs under general anesthesia. In a pilot study in one pig, scintigraphic evaluation of arterial perfusion to t

The aim of this study was to describe the clinical characteristics in relation to final amputation level in diabetic patients with foot ulcers. In a prospective series, 187 consecutively presenting patients were investigated. From admission until final outcome, the patients were treated by a multidisciplinary team both as in- and out-patients. All the patients had one or more signs of neuropathy a

ProteomeBinders is a new European consortium aiming to establish a comprehensive resource of well-characterized affinity reagents, including but not limited to antibodies, for analysis of the human proteome. Given the huge diversity of the proteome, the scale of the project is potentially immense but nevertheless feasible in the context of a pan-European or even worldwide coordination.

Two short (< 2 s) gamma-ray bursts (GRBs) have recently been localized(1-4) and fading afterglow counterparts detected(2-4). The combination of these two results left unclear the nature of the host galaxies of the bursts, because one was a star-forming dwarf, while the other was probably an elliptical galaxy. Here we report the X-ray localization of a short burst (GRB 050724) with unusual gamma-ra

Sugarcane bagasse was pre-treated by steam explosion at 205 and 215degreesC and hydrolysed with cellulolytic enzymes. The hydrolysates were subjected to enzymatic detoxification by treatment with the phenoloxidase laccase and to chemical detoxification by overliming. Approximately 80% of the phenolic compounds were specifically removed by the laccase treatment. Overliming partially removed the phe

Most evolutionary models of dispersal have concentrated on dispersal rate, with emigration being either global or restricted to nearest neighbours. Yet most organisms fall into an intermediate region where most dispersal is local but there is a wide range of dispersal distances. We use an individual-based model with 2500 patches each with identical local dynamics and show that the dispersal distan

Collagen-induced arthritis (CIA) is induced in H-2(q) mice after immunization with rat type II collagen (CII). The immunodominant T cell epitope on heterologous CII has been located to CII256-270. We have previously shown that TSC transgenic mice, which express the heterologous epitope in type I collagen (CI), e.g. in skin, are tolerized against rat CII and resistant to CIA. In this study we trans

The aim of the present study was to investigate whether current smoking, ex-smoking, or amount of current smoking among postmenopausal women was associated with plasma levels of testosterone, and rostenedione, and DHEAs. About 65,000 women in Sweden have participated in two population-based prospective cohort studies where blood samples were collected at baseline, and information on life-style, re

We have examined the variations in gene content and sequence divergence that could be associated with symbiotic adaptations in the ectomycorrhizal fungus Paxillus involutus and the closely related species Paxillus filamentosus. Strains with various abilities to form mycorrhizae were analysed by comparative genomic hybridizations using a cDNA microarray containing 1076 putative unique genes of P. i

Local desaturation-elongation of linoleic acid, uptake of 2-arachidonyl-lysophosphatidylcholine, and uptake plasma unesterified arachidonic acid (AA) are assumed to be the most important sources of AA for extrahepatic tissues. In this study, we investigated the clearance rate as well as the retention rate of plasma unesterified (14)C-AA in different tissues in fed rats. The initial half-life of (1

The majority of patients with von Willebrand disease (VWD) have a mild bleeding tendency that primarily involves mucosal bleeding. Some patients with the disorder, however, have severe episodes of mucosal or joint bleeding that can hamper daily activities and lead to significant joint impairment. Experience in the setting of severe hemophilia has shown the feasibility and benefits of prophylactic

We have developed force-field parameters for the hydrogen-abstraction transition state of aliphatic hydroxylation by cytochrome P450 using the Q2MM approach. The parametrization is based on quantum chemical (B3LYP) transition-state structures and Hessian matrices for 24 diverse substrate models (14 in the training set and 10 in the test set). The force field is intended to be applicable to any dru

The ability of many animals to camouflage themselves against a background is a well-known daytime phenomenon. Now it has even been found to occur at night, highlighting the reality of nocturnal visual predation

A number of human-centred methodologies-subjective, objective, and combined-are used for slipperiness measurement. They comprise a variety of approaches from biomechanically-oriented experiments to psychophysical tests and subjective evaluations. The objective of this paper is to review some of the research done in the field, including such topics as awareness and perception of slipperiness, postu

Sensitization of guinea pigs by intradermal injections of the occupational allergen trimellitic anhydride (TMA) in oily vehicle has been shown to be very reproducible. We studied the effect of intradermal sensitization with ovalbumin (OA) in oily vehicle on immune and airway responses in guinea pigs. We also compared airway responses to trimellitic anhydride or Dermatophagoides farinae (DF; mite)

The actinomycete Corynebacterium glutamicum grows as rod-shaped cells by zonal peptidoglycan synthesis at the cell poles. In this bacterium, experimental depletion of the polar DivIVACG protein resulted in the inhibition of polar growth; consequently, these cells exhibited a coccoid morphology. This result demonstrated that DivIVA is required for cell elongation and the acquisition of a rod shape.
