Constraints on the Late Saalian to early Middle Weichselian ice sheet of Eurasia from field data and rebound modelling

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

Changes in the distribution of hepatic arterial blood flow following TIPS with uncovered stent and stent-graft: An experimental study

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

House sparrows (Passer domesticus) adjust their social status position to their physiological costs

For group-living animals, the maintenance of a position in the social hierarchy may be associated with physiological costs such as increased stress and energy expenditure or suppressed immune functions. In this study, we experimentally manipulated the social status of house sparrows so that each bird experienced two social environments in random sequence: being dominant and subordinate. For 14 mal

Literature on eating disorders during 40 years: Increasing number of papers, emergence of bulimia nervosa

The growth of the literature on eating disorders during four decades is described, especially the development of literature on bulimia. The study is based on a database, ED40, that contains more than 14,000 references to articles on ED from 1960 to 1999. The references were imported from Medline(R) and PsycINFO(R). A broad search method included articles on the physiology of hunger and satiety. Th

The burden of rheumatoid arthritis and access to treatment: determinants of access

As pan of the study "The Burden of Rheumatoid Arthritis (RA) and Patient Access to Treatment", this paper reviews the impact on access to RA drugs of the approval processes, pricing and funding decisions and times to market (access) in different countries. In addition, an overview of health technology assessments (HTA) and the economic literature related to RA treatments is provided. The time from

Balanced chromosome abnormalities inv(16) and t(15;17) in therapy-related myelodysplastic syndromes and acute leukemia: Report from an international workshop

The Workshop identified 48 unselected patients with therapy-related myelodysplastic syndrome or acute myeloid leukemia (t-MIDS/t-AML) and inv(16), and 41 patients with t(15; 17) after chemotherapy (CT) and/or radiotherapy (RT) for a malignant or nonmalignant disease. The primary diseases were: breast cancer, 33 patients; lymphomas, 24 patients; various other solid tumors, 30 patients; and nonmalig

Goodpasture disease. Characterization of a single conformational epitope as the target of pathogenic autoantibodies

Goodpasture disease is a prototype autoimmune disease characterized by the formation of autoantibodies against the heterotrimeric basement membrane collagen type IV, which causes a rapidly progressive glomerulonephritis. The pathogenic antibody response is directed to the non-collagenous (NC1) domain of the alpha3 chain of type IV collagen (alpha3(IV)NC1), but not to the homologous region of the a

Extended mitogenomic phylogenetic analyses yield new insight into crocodylian evolution and their survival of the Cretaceous–Tertiary boundary

caiman, Paleosuchus trigonatus, and Cuvier’s dwarf caiman, Paleosuchus palpebrosus, were sequenced and included in a mitogenomic phylogenetic study. The phylogenetic analyses, which included a total of ten crocodylian species, yielded strong support to a basal split between Crocodylidae and Alligatoridae. Osteolaemus fell within the Crocodylidae as the sister group to Crocodylus. Gavialis and Tomi

Combined UV-biological degradation of PAHs

The UV-photolysis of PAHs was tested in silicone oil and tetradecane. In most cases, the degradation of a pollutant provided within a mixture was lower than when provided alone due to competitive effects. With the exception of anthracene, the larger pollutants (4- and 5-rings) were always degraded first, proving that UV-treatment preferentially acts on large PAHs and thereby provides a good comple

The role of human glandular kallikrein 2 for prediction of pathologically organ confined prostate cancer

BACKGROUND. In recent studies serum levels of human glandular kallikrein 2 (hK2) demonstrated significant differences in pathologically organ-confined versus non-organ-confined prostate cancer (Pca). In this study we investigated whether hK2 adds independent information when considered together with traditionally used parameters to predict organ confined (pT2a/b) PCa. METHODS. Serum levels of hK2,

Phase behavior of the phytantriol/water system

Phytantriol, 3,7,11,15-tetramethyl-1,2,3-hexadecanetriol, is frequiently used as a cosmetic ingredient; however, very little is known about its physical and chemical properti s. Here, we present the phase behavior of phytantriol in water, as determined by X-ray diffraction. At room temperature, the phase sequence upon increasing the water concentration is reversed micellar, lamellar, cubic phase Q

A Mesoscopic Model for Protein-Protein Interactions in Solution

Protein self-association may be detrimental in biological systems, but can be utilized in a controlled fashion for protein crystallization. It is hence of considerable interest to understand how factors like solution conditions prevent or promote aggregation. Here we present a computational model describing interactions between protein molecules in solution. The calculations are based on a molecul

How often is a low 5-min Apgar score in term newborns due to asphyxia?

Objective: To evaluate how often low 5-min Apgar scores (AS(5-min)) at term are associated with asphyxia. Study design: A cohort- and case-control study, including all 183 term infants with AS(5-min) below 7 born at Lund University Hospital during 1993-2002, antepartum deaths excluded. The control group included 183 randomly selected term newborns with AS(5-min) 9-10. Cardiotocography (CTG) traces

Quantitative role of plasma free Fatty acids in the supply of arachidonic Acid to extrahepatic tissues in rats.

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

Interaction between herpes simplex type 1-induced Fc receptor and human and rabbit immunoglobulin G (IgG) domains

Cells infected with herpes simplex virus type 1 (HSV-1) express a cell surface receptor able to bind to the Fc region of immunoglobulin G (IgG). The ability of HSV-1-infected cells to bind 125I-labelled human and rabbit IgG and IgG fragments was studied to localize the site of interaction to the C gamma 2 or C gamma 3 domains of IgG. 125I-labelled IgG and IgG Fc fragments consisting of C gamma 2 a
