Trace impurities in lead-tin solders were determined using inductively coupled plasma atomic emission spectrometry (ICP-AES) for the forensic discrimination of solder samples from different origins by a comparison of the concentration for each element. After about 10 mg of sample was accurately measured and taken into a glass tube, 1 ml of HNO3 was added. The tube was capped and heated at 80 de...

Studies to specify metal-binding species, such as metalloproteins that are present in trace amounts in colonic cell cytosol, using chromatographic separation methods in combination with inductively coupled plasma mass spectrometry (ICP-MS) as element-specific detection require an optimised sample preparation regarding the solubilisation of the proteins. Focus should be taken to avoid metal cont...

BACKGROUND Phenylketonuria (PKU) is caused by a severe phenylalanine hydroxylase deficiency; the mainstay of treatment is a low-phenylalanine diet. A diet which is so restrictive is associated with a risk of nutritional deficiencies. We investigated plasma concentrations for 46 elements, including minerals and trace elements. METHODS We enrolled 20 children and adolescents with PKU and 20 mat...

OBJECTIVES Retrospective studies in patients with primary brain tumors or other central nervous system pathologies as well as postmortem studies have suggested that gadolinium (Gd) deposition occurs in the dentate nucleus (DN) and globus pallidus (GP) after multiple administrations of primarily linear Gd-based contrast agents (GBCAs). However, this deposition has not been associated with any ad...

The atmospheric deposition of As, Cd, Cu, Cr, Fe, Ni, V, and Zn in Albania was investigated by using the carpet-forming moss species (Hypnum cupressiforme) as bioindicators. This research is a part of the international program (International Cooperative Programme (ICP) Vegetation, UNECE) that had carried out in the most of European countries since 1987, by investigating the impacts of air pollu...

purpose: to evaluated the correlation between intracranial pressure (icp) and intraocular pressure (iop). methods: this interventional case series included 90 patients undergoing lumbar puncture (lp) for neurologist evaluation. iop was measured before and 1 hour after the lp by using goldmann tono-meter. patients were compared into two groups: patients with normal icp (<20 cmh2o) and patients w...

A procedure was developed for the determination of element distributions in cross-sections of ferromanganese concretions using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The effects of carrier flow rates, rf forward power, ablation energy, ablation spot size, repetition rate and number of shots per point on analyte intensity were studied. It is shown that different...

Fresh and freeze-dried sample sections of the coastal macroalgae, Fucus serratus and F. vesiculosus, and the brackish water macroalga, F. ceranoides, have been analysed for trace elements by field-portable-X-ray fluorescence (FP-XRF) spectrometry using a Niton XL3t in a low density mode with thickness correction. When analysed fresh in a laboratory accessory stand for a period of 200 seconds, A...

Objective: This article describes a novel method for processing continuous intracranial pressure (ICP) signals with lifting wavelet transformation and discrimination rules for ICP waveform morphology. Methods: First, lifting wavelet was applied to detect the extreme points of ICP waveform preliminarily; then, the extreme points that were undetected or falsely detected are determined by using th...
