This article reports the organ distribution and bioaccumulation of hepatotoxic microcystins (MCs) in freshwater fishes at different trophic levels from the large, shallow, eutrophic Lake Chaohu in September 2003, when there were heavy surface blooms of toxic cyanobacteria. Among all fish, intestines and blood had the highest average content of MC-RR + MC-LR (22.0 and 14.5 microg g(-1) DW, respe...

We present new observations of the cataclysmic variable DW Cancri, after system recovered from a low state. performed power spectrum analysis that reveals clear signal 38 min spin period in our photometric data. Our spectroscopic search was consistent with studies before state, showing orbital and modulations. Doppler Tomography study exhibits disc structure an enhanced asymmetric region, possi...

The present study was carried out to assess the status of various hormones responsible for the flower induction of Nagal, Lulu, and Khalas date palm varieties in UAE. The nonenzymatic antioxidant compounds and the antioxidant enzymatic activities at preflowering, flowering, and postflowering stages of the date palm varieties were quantified. The ABA and zeatin concentrations were found to be si...

BACKGROUND Iron deficiency and poor linear growth are common in infants from deprived socioeconomic backgrounds and may be associated with inadequate complementary feeding (CF) practices. OBJECTIVE We tested the hypothesis that new CF guidelines emphasizing meat as a source of iron and zinc would improve linear growth, iron, and zinc status in infants living in poor socioeconomic circumstance...

Domain wall (DW) pinning in ferromagnetic nanowires is in general a complex process. Distortions of the DW shape make quantitative agreement between modeling and experiment difficult. Here we demonstrate pinning using nanometer scale localized stray fields. This type of interaction gives well-characterized, tailorable potential landscapes that do not appreciably distort the DW. Our experimental...

In the past few years, the data warehouse (DW) has regained experts’ interest due to the paradigm shift from data storages to data analysis. During the development of DWs data passes through a number of transformations and are staged in multiple storages which might lead to data corruption and/or manipulation. Hence, testing DWs is a vital stage in the DW development life cycle. In this paper, ...

Web Data Warehouses have been introduced to enable the analysis of integrated Web data. One of the main challenges in these systems is to deal with the volatile and dynamic nature of Web sources. In this work we address the effects of adding/removing/changing Web sources and data items to the Data Warehouse (DW) schema. By managing source evolution we mean the automatic propagation of these cha...

PURPOSE To evaluate the therapeutic and biological effects of CHIR-258, an orally bioavailable, potent inhibitor of class III-V receptor tyrosine kinases, in colon cancer models. EXPERIMENTAL DESIGN The pharmacologic activity of CHIR-258 was characterized by monitoring target modulation as well as by evaluating the antitumor and antiangiogenic effects in human colon xenograft models. RESULT...

Introduction Diffusion-weighted MRI (DWI) provides a non-invasive method for in vivo evaluation of tissue water mobility. Most DWI studies employ single-shot DWEPI techniques which can suffer severe artifacts and image distortion in abdominal imaging applications. Multi-shot TSE-based DW-PROPELLER [1] may overcome these limitations. DW-PROPELLER for brain [2] and abdominal [3] imaging has demon...
