Summary: The aim of this study was to investigate the stress induced by the urban environment on trees and its impact on the condition of the crown. The study found correlations between variables such as crown density (Cdn), crown transparency (Ctr) and vegetation indices such as normalized difference vegetation index (NDVI) and blue-normalized difference vegetation index (BNDVI). Therefore, it is possible to evaluate the health condition of trees in urban green areas by using vegetation indices.

Summary: This study developed a sensitive method to measure the metallic components of atmospheric fine particulate matter (PM2.5) and compared the results with different analysis methods. The concentrations of metallic components in personal PM2.5 samples were found to be significantly different from corresponding fixed-site samples. Personal sampling can reduce exposure misclassifications, and measuring metallic components is useful for exploring health risks and identifying sources of PM2.5.

Summary: In this case report, we present a 47-year-old female patient with right-sided cardiac device-related infective endocarditis of the pacemaker leads, primarily in the right atrium and right ventricle, with vegetations and complicated by pulmonary embolism. The patient had a history of pacemaker implantation and was later diagnosed with systemic lupus erythematosus, receiving immunosuppressive therapy. Prolonged intravenous antibiotic treatment was initiated, and both the atrial and ventricular leads were removed, along with posterior leaflet shaving of the tricuspid valve.

Summary: The morphology of MnS inclusions in sulfur-bearing free-cutting steel is crucial for determining steel performance, and it is necessary to accurately characterize and control their morphology. Changes in MnS inclusion morphology during heating can affect steel properties. X-ray Micro-CT can provide a comprehensive characterization of the three-dimensional morphology of MnS inclusions.

Summary: Pollutants released from pharmaceutical, steel, paper, and battery industries into water cause irreparable damage to the biotic system by entering the natural ecosystems and human food chain. Monitoring and determining heavy metal levels in water are crucial for human beings. In this study, TXRF spectrometry technique was used to assess the contaminant levels in water samples from an industrial area. The elemental concentrations were compared to the guidelines from WHO and BIS, and water quality parameters were assessed. The results showed that some water samples were unfit for drinking with high levels of lead and other heavy metals.

Summary: In this study, the relative intensities of L-subshell x-ray fluorescence (XRF) for elements with atomic numbers 62≤Z≤83 were measured at two excitation energies, 18 keV and 23 keV, using a synchrotron radiation source at SESAME in Jordan. The experimental results were compared with theoretical calculations based on the subshell fluorescence yield and transition probabilities, and good agreement was found. This research also measured the L XRF relative intensities for specific elements at energies of 18 keV and 23 keV.

Summary: In the lungs, asbestos forms Asbestos Bodies (AB) with a Fe-rich coating, serving as the interface between foreign fibers and the host organism. A novel combination of x-ray tomography and spectroscopy allowed the study of unaltered lung tissue samples containing chrysotile and crocidolite asbestos. The composition of all ABs analyzed was similar, indicating possible sources of Fe from the fibers or the host organism, with a decrease in silicon concentration from core to rim.

Summary: White-beam Laue synchrotron X-ray diffraction is used to study the erratic behavior of grain reorientation in fine-grained, as-rolled magnesium alloy during an in situ heating experiment. The observation of grain rotations and coalescence provides crucial insights into anomalous grain growth, a phenomenon that has long been postulated but lacked observational methods. The findings have implications for a wide range of materials undergoing grain growth, creep, and superplasticity.

Summary: Gas desorption from copper tubes coated with Pd or Pd/TiZrV in response to synchrotron radiation was investigated. The results showed that Pd/TiZrV film exhibited lower H2 desorption yield compared to TiZrV film. Pd film had a higher H2 pumping rate and was more likely to release H2 and CO during activation, which reduced the photon-stimulated desorption yield of the Pd layer.

Summary: This study demonstrates the use of fluorescent nanodiamonds (FNDs) with nitrogen-vacancy (NV) centers as scintillators for imaging and characterizing extreme ultraviolet (EUV) radiation. The FNDs form a stable thin film and can emit bright red fluorescence when excited by EUV light. An FND-based imaging device has been developed for beam diagnostics of synchrotron radiations.

Summary: In this study, fluorescent nanocomposite films were prepared by solution mixing of polyvinyl alcohol (PVA) and tryptophan functionalized silver (AgTrp) nanoparticles. The distribution of AgTrp nanoparticles within the polymer matrix was tracked using synchrotron excitation deep-ultraviolet fluorescence imaging. The presence of AgTrp nanoparticles resulted in the pronounced growth of dendrite-like structures, which was confirmed by various imaging techniques. Both tryptophan and AgTrp nanoparticles affected the thermal properties of the matrix, reducing crystallinity and increasing the glass transition temperature of PVA. Furthermore, the films showed a significant increase in conductance under illumination with 250 nm light, with the relative changes reaching almost 200% compared to the dark condition.

Summary: The study found that two new B. subtilis strains showed strong in vitro activity against ESBL-E. coli, significantly reducing their titers in an in vitro model. However, these strains did not decrease the fecal titers of ESBL-E. coli in a murine intestinal colonization model, highlighting the importance of in vivo experiments to evaluate the efficacy of probiotics.

Summary: The lipid composition and balance in cellular membranes can be influenced by various factors, including aging, pathologies, and diets. In individuals with psychiatric disorders, such as schizophrenia, the cell membranes have been found to be deficient in polyunsaturated fatty acids (PUFAs), which could impact the interaction of medications and the activation of receptors embedded in the lipid membrane. Understanding how changes in PUFA levels affect membrane properties is crucial.

Summary: Increasing evidence suggests a connection between lipid metabolism and mental health, particularly in relation to polyunsaturated fatty acids (PUFAs). Recent findings show that PUFA levels in the brain are linked to dopamine transmission, a key system involved in psychiatric symptoms. However, the underlying mechanisms of this relationship are still unclear.
