Lead nanoparticles (PbNPs) in air pollution pose a significant threat to human health, especially due their neurotoxic effects. In this study, we exposed mice lead(II) oxide (PbONPs) inhalation chambers mimic real-life exposure and assess impact on the brain. PbONPs caused formation of Hirano bodies pathological changes related neurodegenerative disorders through cytoskeletal disruptions without induction inflammation. Damage astrocytic endfeet capillary endothelial cells indicated...
Abstract Contents of Ga and Ge in granites, rhyolites, orthogneisses greisens different geochemical types from the Bohemian Massif were studied using inductively coupled plasma mass spectrometry analysis typical whole-rock samples. The contents both elements generally increase during fractionation granitic melts: 16 to 77 ppm 1 5 ppm. differences between strongly peraluminous (S-type) slightly (A-type) granites negligible. elemental ratios Si/1000Ge Al/1000Ga significantly decreased magmatic...
The paper presents the results of aluminium determinations in ground water samples Miocene aquifer from area city Poznań (Poland). determined content amounted <0.0001 to 752.7 $\upmu $ g L − 1. were performed using three analytical techniques: graphite furnace atomic absorption spectrometry (GF-AAS), inductively coupled plasma emission (ICP-AES) and mass (ICP-MS). groundwater for particular techniques compared. used identify ascent Mesozoic fault graben. Using Mineql+ program, modelling...
The quantification capabilities of iron-based samples were investigated using three commercially available ultraviolet (UV) nanosecond (ns) and femtosecond (fs) laser ablation systems coupled to inductively plasma mass spectrometry (LA-ICP-MS). A comparison pulsed (ArF* excimer, Nd:YAG Ti-sapphire) with different wavelengths pulse time durations (15 ns, 4 ns 150 fs, respectively) was performed. Minor trace elements determined 57Fe as internal standard element. Using similar spatial...
FT Raman spectroscopy and micro‐Raman with lasers of three different wavelengths (1064 nm, 785 nm 532 nm) were used for analysis reference samples natural clay pigments including white minerals (kaolinite, illite, montmorillonite), green earths (glauconite celadonite) red (natural mixtures hematite). In addition, eight micro‐samples obtained from historical paintings containing in ground colour layers have been examined. Powder X‐ray diffraction micro‐diffraction as supplementary methods. It...
Abstract The compositions of trioctahedral micas from 51 samples granitoids with different geochemical affiliations and grades differentiation the Bohemian Massif, Central Europe, were analysed using electron microprobe (major elements) laser ablation inductively coupled plasma mass spectrometry (Li, Sc, Ga, Ge, Nb, In, Sn, Cs, Ta, W, Tl). form a continuous evolutionary series phlogopite to zinnwaldite. phlogopites biotites I-type rocks are characterized by 5.5–5.7 Si, 2.4–2.6 Al, <0.1 Li...
Wedelolactone is a multi-target natural plant coumestan exhibiting cytotoxicity towards cancer cells. Although several molecular targets of wedelolactone have been recognized, the mechanism its has not yet elucidated. In this study, we show that acts as an inhibitor chymotrypsin-like, trypsin-like, and caspase-like activities proteasome in breast The inhibitory effect was documented by (i) reduced cleavage fluorogenic substrates; (ii) accumulation polyubiquitinated proteins with rapid...
A collinear 1064 nm double pulse Laser-induced breakdown spectroscopy was used for analysis of green algae on a cellulose filter. Intensities the contaminant elements Zn, Ni and those some matrix lines C I, Ca II, K Mg Mn Na H O I were measured compared various numbers tape layers filter fixation onto microscope glass slide. This arrangement simulated surface modifications which can substantially lower intensities. Maximum intensities 1 or 2 lowest 6 filters with contaminated algae; however,...
Laser-induced breakdown spectroscopy (LIBS) and laser ablation (LA) inductively coupled plasma (ICP) mass spectrometry (MS) were utilized for microspatial analyses of a prehistoric bear (Ursus arctos) tooth dentine. The distribution selected trace elements (Sr, Ba, Fe) was measured on 26 mm×15 mm large 3 thick transverse cross section canine tooth. Na Mg content together with the matrix (Ca, P) also monitored within this area. depth LIBS craters an optical profilometer. As shown, both...
In the past couple of years, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been widely used for trace element analysis in solid samples and study their distribution.
The aim of the study was to determine content particular elements Ca, Mg, P, Na, K, Zn, Cu, Fe, Mo, Cr, Ni, Ba, Sr, and Pb in proximal femur bone tissue (cancellous cortical bone) 96 patients undergoing total hip replacement for osteoarthritis using ICP-AES FAAS analytical techniques. interdependencies among these their correlations depended on factors including age, gender, place residence, tobacco consumption, alcohol exposure environmental pollution, physical activity, type degenerative...
