Death-associated protein kinase is activated by dephosphorylation in response to cerebral ischemia

Death-associated protein kinase (DAPK) is a calcium calmodulin-regulated serine/threonine protein kinase involved in ischemic neuronal death. In situ hybridization experiments show that DAPK mRNA expression is up-regulated in brain following a global ischemic insult and down-regulated in ischemic tissues after focal ischemia. DAPK is inactive in normal brain tissues, where it is found in its phosp

The general Leigh-Strassler deformation and integrability

The success of the identification of the planar dilatation operator of N = 4 SYM with an integrable spin chain Hamiltonian has raised the question if this also is valid for a deformed theory. Several deformations of SYM have recently been under investigation in this context. In this work we consider the general Leigh-Strassler deformation. For the generic case the S-matrix techniques cannot be use

Sequence Variation and Haplotype Structure Surrounding the Flowering Time Locus FRI in Arabidopsis thaliana.

Linkage disequilibrium in highly selfing organisms is expected to extend well beyond the scale of individual genes. The pattern of polymorphism in such species must thus be studied over a larger scale. We sequenced 14 short (0.5-1 kb) fragments from a 400-kb region surrounding the flowering time locus FRI in a sample of 20 accessions of Arabidopsis thaliana. The distribution of allele frequencies,

Bladder activation: afferent mechanisms.

The major function of the lower urinary tract is to store and periodically evacuate urine from the bladder. This requires coordination of the smooth muscles of the bladder and urethra, and of the striated muscles of the outflow region and pelvic floor by a complex neural control system. Lumbosacral afferent fibers (pelvic afferents), but also afferents in the hypogastric and pudendal nerves, are o

Early highly aggressive MS successfully treated by hematopoietic stem cell transplantation

Background During the last 15 years, high-dose chemotherapy with autologous hematopoietic stem cell transplantation (HSCT) has globally been performed for severe multiple sclerosis (MS). Most patients have been in progressive phase with long disease duration. As a rule, treatment effect has been minor or moderate. Patients Since 2004, we have performed HSCT in nine young patients with "malignant"

Biodiversity, disturbances, ecosystem function and management of European forests

We review the effects of human impact on biodiversity of European forests in the light of recent views on disturbances and succession in ecosystems, and discuss recent ideas on how biodiversity affects ecosystem functions such as productivity and ecosystem stability. With this as a background we discuss how to better manage European forests for both production and biodiversity. We argue that the n

Down-regulation of alpha-adrenoceptor expression by lipid-soluble smoke particles through transcriptional factor nuclear factor-kappaB pathway.

Smoking is a strong risk factor for cardiovascular disease that is a leading cause of death and disability in Western countries. The present study was designed to investigate the effect of lipid-soluble smoke particles (DSP) on alpha-adrenoceptor expression in organ culture of rat mesenteric arteries and human epiploon arteries. Myograph and real-time reverse transcription-polymerase chain reactio

Clustering of deletions on chromosome 13 in benign and low-malignant lipomatous tumors

Deletions and structural rearrangements of the long arm of chromosome 13 are frequently observed in benign and low-malignant lipomatous tumors, but nothing is known about their molecular genetic consequences. We assessed the karyotypes of 40 new and 22 previously published cases (35 ordinary lipomas, 15 spindle cell/pleomorphic lipomas, 2 myxolipomas, 1 angiomyxolipoma and 9 atypical lipomatous tu

Zooplankton feeding on algae and bacteria under ice in Lake Druzhby, East Antarctica

The feeding of the cladoceran Daphniopsis studeri on algae and bacteria was investigated under ice in an ultra-oligotrophic Antarctic lake from late autumn (May) to early spring (October) in 2004. D. studeri fed on both algae and bacteria with estimated filtering rates of 0.048 and 0.061 l ind(-1) day(-1)), respectively. Algae seemed to be the major food resource for the D. studeri population, how

Dimethylsulfoxide-soluble Smoking Particles and Nicotine Affect Vascular Contractibility

The aim is to study the effect of dimethylsulfoxide-soluble smoking particles (DSP) and nicotine on the contractility of rat mesenteric artery. The superior mesenteric artery segments were cultured with DSP or nicotine for 24 h. The vascular contractibility was recorded with myograph system. DSP 0.4 mL/L and nicotine 0.48 and 0.96 mg/L shifted the concentration-contractile curves induced by sarafo

Effects of inoculation strategy and cultivation approach on the performance of microbial fuel cell using marine sediment as bio-matrix

Aims: To investigate the effects of inoculation strategy and cultivation approach on the performance of microbial fuel cell (MFC). Methods and Results: A dual-chamber sediment fuel cell was set up fed with glucose under batch condition. At day 30, the supernatant consortium was partly transferred and used as inoculum for the evaluation of cultivation approach. Power output gradually increased to 9

Congenital and acquired activated protein C resistance.

Resistance to the anticoagulant action of activated protein C, APC resistance, is a highly prevalent risk factor for venous thrombosis among individuals of Caucasian origin. In most cases, APC resistance is associated with a single missense mutation in the gene for coagulation factor V (FVLeiden), which predicts the replacement of Arg506 with a Gln at one of the cleavage sites for APC in factor V.

Analyzing tumor gene expression profiles

A brief introduction to high throughput technologies for measuring and analyzing gene expression is given. Various supervised and unsupervised data mining methods for analyzing the produced high-dimensional data are discussed. The main emphasis is on supervised machine learning methods for classification and prediction of tumor gene expression profiles. Furthermore, methods to rank the genes accor

The Environmental Implications of Electronic Commerce - A Critical Review and Framework for Future Investigation

There are accelerating trends for the implementation of electronic commerce(e-commerce) as an extra marketing channel for selling products globally via the access of the Internet. This is expected to in¯uence the shape of future cities and the conservation of natural resources. This paper critically reviews the current research work to date regarding the environmental implications of e-commerce. T

Genetic variation in the ADIPOR2 gene is associated with liver fat content and its surrogate markers in three independent cohorts

Aims: We investigated whether polymorph isms in candidate genes involved in lipid metabolism and type 2 diabetes are related to liver I, at content. Methods: Liver fat content was measured using proton magnetic resonance spectroscopy (H-1-MRS) in 302 Finns, in whom single nucleotide polymorphisms (SNPs) in acyl-CoA synthetase long-chain family member 4 (ACSL4). acliponectin receptors 1 and 2 (ADIP

Influences of dietary adaption and source of resistant starch on short-chain fatty acids in the hindgut of rats.

The effect of adaptation time on the concentration and pattern of short-chain fatty acids (SCFA) formed in the hindgut of rats given resistant starch (RS) in the form of raw potato starch (RPS) or high-amylose maize starch (HAS) was evaluated. Each starchy material was tested in diets containing 100 g indigestible carbohydrates/kg DM, and fed for 13, 28 and 42 d. At the end of each period, the con
