BACKGROUND. The objective of this study was to evaluate the efficacy and safety of atrasentan (Xinlay), a selective endothelin-A receptor antagonist, in patients with metastatic hormone- refractory prostate cancer (HRPC). METHODS. This multinational, double-blind, placebo-controlled trial enrolled 809 men with metastatic HRPC. Patients were randomized 1:1 to receive either atrasentan 10 mg per day

A conodont fauna including several species of Cordylodus was retrieved from two glacial siltstone boulders found on the shore of Lilltuppen, a small island immediately off the Swedish coast in the Gulf of Bothnia at c. 61 degrees N, 17 degrees E. The erratics are remnants of a poorly known level in the Swedish stratigraphic succession. They probably derive from a nearby point on the floor of the B

Spectral karyotyping (SKY) on metaphase spreads from 15 high hyperdiploid (>51 chromosomes) childhood acute lymphoblastic leukemias (ALL), which typically display a poor chromosome morphology, was performed in order to investigate the pattern of numerical abnormalities, reveal the chromosomal origin of marker chromosomes, and identify translocations and other interchromosomal rearrangements not de

The influence of sorption on the mineralisation of 50 mug aniline l(-1) was examined in an aquifer material under batch conditions. The study was designed to distinguish the rates and extent of biodegradation of the sorbed and the dissolved trace organic and the contribution of sorbed and suspended bacteria to the degradation. Four different mathematical models were developed with different assump

It has been observed that bread containing lactic acid produced during the sourdough fermentation or added directly, has the ability to lower the postprandial glucose and insulin responses in humans. The main objective of the present work was to evaluate the possible mechanisms for a lowered glucose response to bread containing lactic acid, and to determine whether the same phenomenon also occurs

Lawful equations describing relations between empirical measurable variables, that are free of fitted parameters, and that can be derived from simple assumptions, are rare in psychology. However, this paper proposes one such equation that describes the relation between the performances on four different explicit episodic memory tests: free recall, cued recall, recognition, and cued recognition. Th

The relationship between adult hippocampal neurogenesis and cognition appears more complex than suggested by early reports. We aimed to determine if the duration and task demands of spatial memory training differentially affect hippocampal neurogenesis. Adult male rats were trained in the Morris water maze in a reference memory task for 4 days, or alternatively working memory for either 4 or 14 da

Lysine acetylation occurs in many protein targets, including core histones, transcription factors, and other proteins. Metastasis-associated protein 1 (MTA1) is implicated in the progression and metastasis of various epithelial tumors. Because MTA1 functions as a transcriptional coregulator, much of its role in cancer promoting processes are likely to involve its ability to regulate the transcript

Au nanoparticles are commonly used as seeds for epitaxial growth of III-V semiconductor nanowires. However, the interaction between Au and In-containing III-V materials makes it difficult to control the growth of more complex nanowire structures in materials such as InAs. Here we report the growth of InAs nanowires and branched nanotrees using Au and Au-In nanoparticles. We show that the initial c

We investigated the time span and spatial scale of regional new particle formation (NPF) events in Finland and Southern Sweden using measured particle number size distributions at five background stations. We define the time span of a NPF event as the time period from the first moment when the newly formed mode of aerosol particles is observable below 25 nm until the newly formed mode is not any m

Productions of tone 4 & tone 3 (mai/mai 'sell'/'buy') in comparable sentences suggests that although the two tones are realized in different ways by different speakers in different speech acts, some features are constant. Tone 3 is connected with a low pitch level throughout the second half of the vowel & tone 4 with a gradual fall over the main part of the vocalic segment. These observati

Perceived control is of significance in occupational therapy, as revealed in empirical research and suggested in practice models. This study investigated the relationship between perceived control and occupational performance in persons with long-term mental illness. The 177 participants were assessed regarding perceived control (locus of control and self-mastery) and occupational performance (act

Semenogelin I and II are the major proteins present in semen coagulum. In the present study, semenogelin I and II were detected in human RPE lysates by proteomic analysis. We further analyzed the expression of these proteins in the retinal cells in vivo and in vitro. Western blots detected semenogelin I and II in both RPE and neural retina while the vitreous contained only SgII. Cryo and paraffin
