The possible involvement of apoplastic reactive oxygen species produced by the oxidation of free polyamines in the leaf growth of salinized maize has been studied here. Salt treatment increased the apoplastic spermine and spermidine levels, mainly in the leaf blade elongation zone. The total activity of polyamine oxidase was up to 20-fold higher than that of the copper-containing amine oxidase....

AIM The main objective of the study was to determine the deleterious effect of fluoride on plasma trace minerals of fluorotic cattle and to evaluate the effect of Tamarindus indica leaf powder toward correction of the same. MATERIALS AND METHODS A total of 30 cattle exhibiting chronic sign of fluorosis and 10 healthy cattle from nonfluorotic area were incorporated in this study. Fluorotic cat...

The aim of this study was to determine the level of heavy metals such as copper, iron, manganese, zinc, lead, nickel, cadmium and chromium concentrated in Juglans regia bark and leaf samples from different localities in Artvin, Turkey. Analysis of the heavy metals Cu, Fe, Mn, Zn, Pb, Ni, Cd and Cr in samples was carried out by inductively coupled plasma optical emission spectroscopy (ICP-OES; P...

Introduction: Giotto (1266–1337) and his workshop realized c. 1315 the large Crucifix now in the Louvre Museum. The conservation of this masterpiece in 2010–2013 in the C2RMF studios gave the opportunity for a comprehensive investigation of the execution technique through a characterization of the paint layers. The first examinations revealed an original gilding and decoration surrounding the C...

Heavy metals found in urban air with its toxic effects have a direct impact on human health. Selection of appropriate tree species and shrub refining capacity of heavy metals in urban areas can greatly reduce the toxic effects of these materials. This study aimed to identify the most suitable tree and shrub species of broadleaf evergreen, deciduous and coniferous refinement of heavy metals lead...

Trace metal contamination is a global health issue. This study evaluated boxed and loose-leaf tea from Bangladesh using Handheld X-ray Fluorescence (XRF) analyzer for lead other metals to rapidly screen as potential hot spot of heavy exposure. Of the 33 elements measured, several priority pollutants were below limit detection (LOD) in all samples, including (LOD 2.17 mg/kg) arsenic 1.68 mg/kg)....

For tumor therapy with protons it is crucial to know the beam range with high accuracy. The Multi-leaf Faraday Cup (MLFC) offers a quick and precise range and energy measurement. Our MLFC is adapted to the eye tumor therapy requirements and has 47 channels; each consists of a 10 μm copper foil (connected to an ammeter) next to a 25 μm KaptonTM foil. A system of absorbers has been constructed to...
