BACKGROUND Traffic exhaust, refineries and industrial facilities are major sources of air toxics identified by the U.S. Environmental Protection Agency (U.S. EPA) for their potential risk to human health. In utero and early life exposures to air toxics such as benzene and 1,3-butadiene, which are known leukemogens in adults, may play an etiologic role in childhood leukemia that comprises the ma...

A new structure related to previously reported structure of 12-tungstoborate Keggin-type polyoxometalate, K5[BW12O40], was synthesized and its characterization by single crystal X-ray diffraction shows the polymorph structure. Further attempts have been performed to provide three component compounds based on L-proline, lanthanoid cation and K5[BW12O40] (BW12 (II)) under hydrothermal conditions ...

The Cover Feature shows the photocatalytic hydrogen production by dual Ru(II)-dye sensitized layered niobate oxide with intercalated Pt cocatalyst in presence of redox-reversible M-substituted polyoxometalate anions (M-POM, M = VIV, MnII). In their Research Article, A. Kobayashi and co-workers found that activity is remarkably higher MnII-POM aq. than VIV-POM despite comparable redox potentials...

We consider the simplest representative of class multiply branched polymer macromolecules, known as a pom-pom structure. The molecule consists backbone linear chain terminated by two branching points with functionalities (numbers side chains) f1 and f2, respectively. In symmetrical case, considered in present study, one has = f2 f total number chains F 2f + 1. Whereas rheological behaviour melt...

A new azide functionalized Anderson polyoxometalate was synthesized, fully characterized and subsequently used as a building block for further POM post-functionalization with organic compounds through a copper catalyzed azide-alkyne cycloaddition (CuAAC) reaction. Optimization of the reaction conditions led to an efficient, fast, convenient and versatile POM coupling method.

The purpose of this research was to (1) determine if different species of wetland vegetation produced characteristically different dissolved organic matter (DOM) based upon both chemical and physical characteristics and (2) determine if any relationships exist between characteristics of DOM derived from freshly senescent tissues of different wetland plant species common to the Florida Everglade...

Filter-feeding invertebrates consume phytoplankton and detritus and therefore serve as important mediators of the exchange of materials from nearshore pelagic to intertidal benthic ecosystems. Here, we evaluated the linkages between nearshore and intertidal systems on temperate rocky reefs on the coasts of Oregon, USA, and New Zealand’s South Island. We used differences in the concentrations of...

In children, any ureter greater than 7 mm in diameter is considered a megaureter based on measurements in fetuses greater than 30 weeks gestation and children <12 years. Primary megaureter (POM) is a result of a functional or anatomical abnormality involving the uretero-vesical junction. Although the endoscopic and surgical techniques to manage POM are successful, we thought that early interven...

Background and Purpose: Invasive aspergillosis (IA) is one of the most common life-threatening fungal infections among the critically ill patients including intensive care unit (ICU) patients. Delayed diagnosis and therapy may lead to poor outcomes. Diagnosis may be facilitated by a test for molecular biomarkers, i.e. detection of galactomannan (GM) antigen based on enzyme immunoassay, which is...
