Wilms tumor is the most frequent renal neoplasm in children, but our understanding of its genetic basis is still limited. We performed cDNA microarray experiments using 63 primary Wilms tumors with the aim of detecting new candidate genes associated with malignancy grade and tumor progression. All tumors had received preoperative chemotherapy as mandated by the SIOP protocol, which sets this study

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

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

Background: Plasma concentrations of inflammatory markers are increased in response to the trauma of cardiac surgery and cardiopulmonary bypass (CPB). It is, however, unknown whether the plasma cytokine levels and cytokine mRNA expression at organ level reflect each other. Methods: Twenty-six piglets (17–19 days) were allocated to the sham-group (sternotomy only, n = 13) or to the CPB-group (ster

This paper describes a new approach to achieve selectivity in an immunoassay by separating the signals given by two cross-reactive compounds present simultaneously in a complex sample matrix. The method is based on the sequential dilution of the sample containing a mixture of the two analytes, spiking each diluted sample with a reference compound, and the detection by enzyme-linked immunosorbent a

A study of past lake-level changes in Lake Xinias covering the last 40 000 years was presented in an earlier paper. In that paper.. changes during the Holocene were only briefly dealt with. because of poor sedimentary representation. In this paper a Supplementary transect of cores is described, in which Holocene lake-level changes are better recorded. The correlation of the cores was based on poll

Photoneutron production on the nuclei of high-Z components of medical accelerator heads can lead to a significant secondary dose during a course of bremsstrahlung radiotherapy, However, a quantitative evaluation of secondary neutron dose requires improved data on the photoreaction yields. These have been measured as a function of photon energy, neutron energy and neutron angle for W-nat, using tag

Introduction: Obstructive sleep apnoea syndrome (OSAS) is a prevalent condition that covaries with cardiovascular complications and most likely with arterial hypertension and diabetes mellitus. Objective: The present paper is a review of the current status of OSAS. Results: Definitions and diagnostic criteria as well as known risk factors, prevalence, symptoms, covariance with other diseases and c

Using 10.7 m and 3 m normal-incidence vacuum ultraviolet spectrographs, we investigated the spectrum of singly ionized potassium in the regions 495 - 612 angstrom and 1247 - 2150 angstrom. More than 120 new K II lines were identified. The previous study on this spectrum was revised and extended. All levels of the 3p(5)4f and 5f configurations as well as the levels of 3p(5)6f based on the 3p(5) P-2

AIMS/HYPOTHESIS: It has been suggested that the uterine environment may influence metabolic disease occurring later in adult life, and that adult stress may promote disease outcome. Using a mouse model, we tested whether in utero exposure to Ljungan virus (LV) followed by adult exposure to stress produces diabetes. The influence of the timing of viral exposure over the course of pregnancy was also

The viscoelastic properties of several multicomponent materials (including both particulate multipolymeric materials and multilayer polymer blends) were investigated in relation to their microstructures and phase-property dependencies. Theoretical considerations based on mechanical modeling were used to explore the origin of additional mechanical transitions in experimental viscoelastic spectra. T

The presence of hypertension aggravates the high cardiovascular risk in type 2 diabetic patients. Pulse pressure is a marker of arterial stiffness and constitutes a risk factor for cardiovascular mortality. This study examines the relationship between different blood pressure indices and mortality in a cohort of type 2 diabetic patients. A total of 1294 type 2 diabetic patients with a median age o

We present a stochastic path integral method to calculate the full-counting statistics of conductors with energy conserving dephasing probes and dissipative voltage probes. The approach is explained for the experimentally important case of a Mach-Zehnder interferometer, but is easily generalized to more complicated setups. For all geometries where dephasing may be modeled by a single one-channel d

Carbon dating of basal peat deposits in Cumberland Bay and Stromness Bay and sediments from a lake in Stromness Bay, South Georgia indicates deglaciation at the very beginning of the Holocene before c. 9500 C-14 yr BP. This post-dates the deglaciation of one local lake which has been ice-free since at least 15 700 C-14 yr BP on account of its atypical geomorphological location. The latter indicate

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.
