We report new occurrences of ca. 1460 Ma magmatism in western Lithuania, where large volumes of granitoid melts were intruded into host supracrustal and charnockitoid rocks, and formed the Zemaiciu Naumiestis pluton. Numerous granitoids of that age have previously been described from southern Sweden and from the Danish island of Bornholm, but none have been reported from the eastern side of the Ba

Nine young, healthy male volunteers were given ethanol (75 g/day) for 5 weeks. The ethanol was divided into five daily doses and taken so that blood ethanol levels never exceeded 0.04% (w/v). During the latter part of the ethanol intake period, there was a significant, transient increase of plasma triglyceride (TG) concentrations followed by reduction to normal levels. A three-fold increase of lip

Bone morphogenetic proteins (BMPs) are expressed and secreted during fracture repair. Although they are likely to be required for this process, little is known about their physiological role in bone regeneration. Noggin is a protein that specifically binds and inactivates several BMPs, It plays fundamental roles during early embryonal development and limb morphogenesis by this BMP-inactivating act

Multiple small infarcts of different ages are common in small-vessel disease. Diffusion-weighted imaging (DWI) is a powerful method for discriminating new from chronic lesions. This can be done on the diffusion-weighted images provided that b is sufficiently high. Our purpose was to determine that critical value of b. We reviewed DWI from a previous study of acute, mainly lacunar strokes, and sele

Apatitic cements have shown excellent biocompatibility and adequate mechanical properties but have slow resorption in the human body. To assure that new bone tissue grows into the bone defect, a certain porosity is necessary although hard to achieve in injectable cements with suitable mechanical properties. An attempt was made by mixing alpha-tricalcium phosphate (alpha-TCP), calcium sulphate hemi

The Shrinking Generator and the Alternating Step Generator are two of the most well known clock-controlled stream ciphers. We consider correlation attacks on these two generators, based on an identified relation to the decoding problem for the deletion channel and the insertion channel, respectively. Several ways of reducing the decoding complexity are proposed and investigated, resulting in “divi

Semenogelin I (SgI) and semenogelin II (SgII) are the dominating protein components of the coagulum formed by freshly ejaculated human semen. The primary source of these proteins is the seminal vesicles and, apart from a small production of SgII in epididymis, they have not been detected in other tissues. In this report, we have re-examined the distribution of SgI and SgII transcripts and protein

Novel hexahydroimidazo[1,2-a]pyridines prepared by the addition of ethyl (1-benzylimidazolidin-2-ylidene)acetate (2) to the fungal metabolite podoscyphic acid (1a) and esters of 1a have been evaluated for their ability to inhibit the inducible TNF-α promoter activity in T cells. The methyl ester 3b is the most potent, inhibiting the TNF-α driven reporter gene expression in Jurkat T cells with an I

Background. Reliable risk estimates for venous thrombosis in families with inherited thrombophilia are scarce but necessary for determining optimal screening and treatment policies. Objectives: In the present analysis, we determined the risk of a first venous thrombotic event in carriers of a thrombophilic defect (i.e. antithrombin-, protein C- or protein S deficiency, or factor V Leiden). Patient

Despite declining incidence rates, gastric cancer (GC) is a major cause of death worldwide. E-Cadherin is an adhesion molecule that is thought to be involved in GC. Germline mutations in the E-Cadherin gene (CDH1) have been identified in hereditary diffuse GC. Also, a promoter polymorphism at position 160 C/A has been suggested to lead to transcriptional down regulation and has been shown to affec

Background The alpha-emitter radium-223 (Ra-223) is a bone-seeking radionuclide studied as a new treatment for patients with bone metastases from hormone-refractory prostate cancer. We aimed to study mature outcomes from a randomised, multicentre, phase II study of Ra-223. Methods Patients with hormone-refractory prostate cancer and bone pain needing external-beam radiotherapy were assigned to fou

Background Genetic engineering of the major birch pollen allergen (Bet v 1) has led to the generation of recombinant Bet v 1 derivatives with markedly reduced IgE-binding capacity, but with retained T cell activating ability. Objective To compare the mucosal reactivity to rBet v 1 derivatives with rBet v 1 wild-type as basis for new therapeutic strategies for birch pollen allergy based on mucosal

A crucial assumption in models of ecological speciation is that reproductive barriers evolve as a consequence of ecological divergence of populations, rather than geographical separation. To test the prediction that barriers between populations might evolve in the face of gene flow, we studied reproductive barriers between populations of two Swedish ecotypes of the marine snail Littorina saxatilis

We present a blow-up criterion for the periodic Camassa-Holm equation. The condition obtained for blow-up uses two of the conservation laws associated with the equation and improves upon some recent results.

To discover whether islet sympathetic nerves are damaged during the autoimmune destruction of islet B-cells, we immunostained sections of pancreas from BioBreeder (BB) diabetic rats, using antibodies against vesicular monoamine transporter 2 (VMAT2), a marker of sympathetic nerve terminals. We found a marked decrease in the VMAT2-positive fiber area in the islets of BB rats that had been diabetic

In several twin studies the relative contribution of genetic factors for personality traits has amounted to figures between 40 and 60%. In the present study we investigated to which degree polymorphisms in the 5-HTT and AP-2 beta genes are implicated in the neural processes involved in the formation of Temperament and Character traits, as estimated by Cloninger's TCI. Considering the background of

Multiple genetic loci confer susceptibility to breast and ovarian cancers. We have previously developed a model (BOADICEA) under which susceptibility to breast cancer is explained by mutations in BRCA1 and BRCA2, as well as by the joint multiplicative effects of many genes ( polygenic component). We have now updated BOADICEA using additional family data from two UK population-based studies of brea

The aim of our retrospective study was to determine the extent to which diffusion- and perfusion- weighted MRI combined with conventional MRI could be helpful in the evaluation of intensive care unit (ICU) patients who have unknown or unclear cerebral pathology underlying a serious clinical condition. Twenty-one ICU patients with disparity between the findings on brain CT scan and their clinical s

The development of bacterial vaginosis (BV) among women of childbearing age and the resulting quantitative and qualitative shift from normally occurring lactobacilli in the vagina to a mixture of mainly anaerobic bacteria is a microbiological and immunological enigma that so far has precluded the formulation of a unifying generally accepted theory on the aetiology and clinical course of BV This cr
