We have developed poly(l-lactide-co-glycolide) (PLGA) based composites using sol–gel derived bioactive glasses (S-BG), previously described by our group, as composite components. Two different types were manufactured that contained either S2—high content silica S-BG, or A2—high lime S-BG. The evaluated in the form of sheets and 3D scaffolds. Sheets containing 12, 21, 33 vol.% each glass characterized for mechanical properties, wettability, hydrolytic degradation, surface bioactivity. A2 S-BG...
Ectosomes (Ects) are a subpopulation of extracellular vesicles formed by the process plasma membrane shedding. In present study, we profiled ectosome-specific microRNAs (miRNAs) in patients with type 2 diabetes mellitus (T2DM) and analyzed their pro- anti-angiogenic potential. Methods: We used different approaches for detecting enumerating Ects, including atomic force microscopy, cryogenic transmission electron nanoparticle tracking analysis. Furthermore, bioinformatics tools to analyze...
In this study, 3D porous bioactive composite scaffolds were produced and evaluated for their physico-chemical biological properties. Polymer poly-L-lactide-co-glycolide (PLGA) matrix modified with sol–gel-derived glasses (SBGs) of CaO–SiO2–P2O5 systems. We hypothesized that SBG incorporation into PLGA would improve the chemical activity materials as well mechanical applied two glasses, designated S2 or A2, differing in content SiO2 CaO (i.e. 80 mol% SiO2, 16 40 52 A2). The composites...
This volume of the IOP Conference Series: Materials Science and Engineering contains papers from 17th Workshop European Microbeam Analysis Society (EMAS) on Modern Developments Applications in Analysis, which took place 7th to 11th May 2023 at Auditorium Maximum Jagiellonian University, Krakow, Poland. The primary aim this series workshops is assess state-of-the-art reliability microbeam analysis techniques. also provide a forum where students young scientists starting out career can meet...
Elemental microanalysis of biological material in the frozen-hydrated state using in-vacuum proton induced X-ray emission is described for first time. For this purpose, a commercially available cryotransfer system was modified and coupled to experimental chamber nuclear microprobe (NMP). The analyzed frozen propane cooled by liquid nitrogen, fractured, carbon coated, transferred onto cold stage (100 K) chamber. Micro-PIXE simultaneous backscattering performed 3 MeV beam. Quantitative results...
Childhood maltreatment, which can take the form of physical or psychological abuse, is experienced by more than a quarter all children. Early life stress has substantial and long-term consequences, including an increased risk drug abuse psychiatric disorders in adolescence adulthood, this higher women men. The neuronal mechanisms underlying influence early adversities on brain functioning remain poorly understood; therefore, current study, we used maternal separation (MS), rodent model...
The aim of the study was analysis Cr distribution in shoots macrophyte Callitriche cophocarpa by means two X-ray-based techniques: micro X-ray fluorescence (μXRF) and electron probe microanalysis (EPXMA). Plants were treated with 100 μM (5.2 mg l(-1)) chromium solutions for 7 days. introduced independently at speciations as Cr(III) Cr(VI), known their diverse physicochemical properties different influence on living organisms. A comparative Cr(III)-treated plants EPXMA μXRF demonstrated high...
The toxic effects of heavy metals on organisms are well established. However, their specific action at the cellular level in different tissues is mostly unknown. We have used housefly, Musca domestica, as a model organism to study toxicity four metals: copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb). These been fed larvae low high, semi-lethal concentrations, accumulation head, thorax, abdomen was subsequently measured adult flies. In addition, impact concentration several elements...
Diagenetic signals from ancient human remains - bioarchaeological applications This preliminary study examines the potential effects of diagenetic processes on oxygen-isotope ratios bone and tooth phosphate (δ 18 O) skeletal material individuals representing Corded Ware Culture (2500-2400 BC) discovered in Malżyce (Southern Poland). Intra-individual variability Ca/P, CI, C/P, collagen content (%) oxygen isotopes was observed through analysis enamel, dentin postcranial bones. Using a variety...
Accumulating evidence from mammalian studies suggests the dual-faced character of heme oxygenase (HO) in oxidative stress-dependent neurodegeneration. The present study aimed to investigate both neuroprotective and neurotoxic effects after ho gene chronic overexpression or silencing neurons Drosophila melanogaster. Our results showed early deaths behavioral defects pan-neuronal overexpression, while survival climbing a strain with were similar over time its parental controls. We also found...
