Trace and Major Elements in Food Articles in Latvia: Root Vegetables It is known that the content of trace and major elements in plants is dependent on several factors, such as type of species, soil properties, climate conditions, agricultural and agrichemical factors, pollution. The aim of the study was to quantify element content of root vegetables grown in farmlands and allotment gardens in Latvia. Samples of onion bulbs and carrot roots were analyzed by atomic absorption spectrometry and inductively coupled plasma mass spectrometry. Quantitative amounts of 17 trace elements (Ag, As, Ba, Cd, Ce, Co, Cr, Cu, La, Mn, Ni, Pb, Rb, Se, Sr, V, Zn) and 5 major elements (Ca, Fe, K, Mg, Na) were determined. It was detected that carrot roots contained higher amounts of several elements than onion bulbs. Differences in element content of vegetables were also detected between the subgroups of samples grown in farmlands versus samples grown in allotment gardens. Data revealed that onions grown in farmlands were more affected by contaminants.

Apple Cultivars

The aim of this study was to investigate the concentration level of some major-to-trace elements and toxic minerals and polyphenols (catechin, epicatechin and quercetin) in fruits belonging to different apple cultivars (‘Auriu de Cluj’, ‘Florina’, ‘Generos’, ‘Golden Delicious’, ‘Prima’, ‘Productiv de Cluj’ and ‘Starkrimson’), under specific climate conditions to northwestern Romania. The apple minerals were determined by the inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma optical emission spectrometry (ICP-OES) after a preliminary, microwave-assisted, acid digestion. The polyphenols were determined by high performance liquid chromatography (HPLC) with MS/MS detection. According to the obtained results, the edible part of the apple contains many minerals with high relative nutritional value (RNV). The major minerals (Na, K, Ca, Mg and P), minor elements (Cu, Fe, Mn, Sr and Zn) and toxic trace elements (Cd, Cr and Pb) were comparatively identified and quantified. It was found that K (31976 mg/kg) was predominant among the major elements, while Fe (3.68 mg/kg) and Cu (3.57 mg/kg) were comparable. The toxic trace metals (Cd, Cr and Pb) were below the limits of detection (0.01, 0.10 and 0.01 mg/kg, respectively) and did not determine any health risk to consumers. The main polyphenols composition (catechin, epicathechin, quercetin) differs slightly among different cultivars. In ‘Idared’ and ‘Jonathan’ cultivars, the investigated polyphenols are in higher quantities comparing to the others. In all investigated apple cultivars, quercetin was proved to be the major polyphenol, followed by epicathechin and catechin. These results suggest that, regarding only the investigated polyphenols, ‘Idared’ and ‘Jonathan’ cultivars have the highest antioxidant character in all investigated genotypes.

BackgroundMost intracranial stents contain nickel alloy, and nickel allergy or hypersensitivity is common. Neurological injury following endovascular treatment with a nickel containing intracranial stent has been reported in patients with purported nickel allergy, but it is unclear whether these reactions represent true nickel hypersensitivity. We quantified nickel release from commonly used intracranial stents to investigate whether such stents should be avoided in patients with nickel allergy.MethodsWe examined nickel release from seven commonly used intracranial stents: Enterprise, LVIS Jr, Neuroform, Wingspan, Zilver, Pipeline Flex Embolization Device, and Surpass Evolve. We incubated each stent in human plasma-like media for 30 days. Dimethylglyoxime (DMG) spot testing was performed on each stent to detect released nickel at 0 and 30 days. Inductively coupled plasma–optical emission spectroscopy (ICP-OES) was then used to quantify the nickel concentration of the media at 30 days. Nickel currency and nickel standard for atomic absorption spectrometry were used as positive controls.ResultsDMG spot tests indicated nickel release only from nickel currency at 0 and 30 days of incubation. No nickel release was detected from any stent at 30 days using ICP-OES.ConclusionsNickel release from commonly used intracranial stents is negligible. These results suggest that previously reported hypersensitivity to these stents may be misattributed to nickel allergy, and that patients with nickel allergy may be safely treated with select nickel-containing stents.
