AbstractThis study investigates the effects of a blend of Hericium erinaceus (lion's mane mushroom) extract on the differentiation of SH-SY5Y cells, a human neuroblastoma cell line, revealing potential therapeutic implications for neuroblastoma management. Treatment with this blend induced cells differentiation towards a neuron-like profile, as evidenced by enhanced neuronal excitability and upregulation of neuronal markers, such as βIII-tubulin and synaptotagmin. Additionally, the treatment significantly reduced PCNA, a key regulator of proliferation, alongside a decrease in stemness markers, indicating a shift toward a more mature and less proliferative phenotype. These findings demonstrate the ability of Hericium erinaceus to promote neuronal differentiation and inhibit proliferation in neuroblastoma cells, highlighting its therapeutic potential for managing neuroblastoma and potentially other neurological disorders. The results suggest that Hericium erinaceus may serve as a promising candidate for the development of novel neuroregenerative therapies.

Research on the relationship of arthropod community diversity or composition with the use of cover crops and soil amendments is limited, despite the widespread application of these soil management strategies. Such research may be particularly important for soil amendments because of the potential for arthropods to bioaccumulate metals or other contaminants. However, the use of a cover crop in conjunction with soil amendments may not only improve the success of a crop but may also decrease bioaccumulation potential by removing contaminants from soils. In this study we investigated how the use of a cover crop (winter cereal rye;Secale cereal) on 100% dredged sediments from the Toledo Harbor altered arthropod diversity, composition and metal concentrations on corn (Zea mays). We further compared these values to those from a nearby traditionally farmed field that did not use a cover crop or soil amendment prior to corn planting. To do so, we surveyed aboveground arthropods along three transects and used pitfall traps for 21 weeks in the dredged sediment plots and two weeks in the traditionally farmed agricultural field. We identified these specimens to species/morphospecies and assigned trophic level based on literature values. Finally, we measured metal concentrations on a subset of arthropods from the dredged sediments and agricultural soil. We observed similar arthropod communities on corn grown on dredged sediments compared to corn grown on traditionally farmed agricultural soil. We further found that the use of a cover crop on 100% dredged sediments did not significantly alter arthropod communities, despite an apparent reduction in arthropod abundance in the cover crop plot compared to the non-cover crop plot. Finally, metal concentrations were similar between arthropods collected from dredged sediments compared to arthropods of the same trophic level collected from traditionally farmed agricultural soils. Our work suggests dredged sediments do not negatively affec

Global ground-level measurements of elements in ambient particulate matter (PM) can provide valuable information to understand the distribution of dust and trace elements, assess health impacts, and investigate emission sources. We use X-ray fluorescence spectroscopy to characterize the elemental composition of PM samples collected from 27 globally distributed sites in the Surface PARTiculate mAtter Network (SPARTAN) over 2019-2023. Consistent protocols are applied to collect all samples and analyze them at one central laboratory, which facilitates comparison across different sites. Multiple quality assurance measures are performed, including applying reference materials that resemble typical PM samples, acceptance testing, and routine quality control. Method detection limits and uncertainties are estimated. Concentrations of dust and trace element oxides (TEO) are determined from the elemental dataset. In addition to sites in arid regions, a moderately high mean dust concentration (6 μg/m) in PM is also found in Dhaka (Bangladesh) along with a high average TEO level (6 μg/m). High carcinogenic risk (>1 cancer case per 100000 adults) from airborne arsenic is observed in Dhaka (Bangladesh), Kanpur (India), and Hanoi (Vietnam). Industries of informal lead-acid battery and e-waste recycling as well as coal-fired brick kilns likely contribute to the elevated trace element concentrations found in Dhaka.

Recent philosophical tendencies of Actor-Network Theory, Object-Oriented Ontology, and Speculative Realism have profoundly challenged the centrality of subjectivity in the humanities, and many artists and curators, particularly in the UK, Germany, and the United States, appear deeply influenced by this shift from epistemology to ontology. October editors asked artists, historians, and philosophers invested in these projectsfrom Graham Harman and Alexander R. Galloway to Armen Avanessian and Patricia Falguieres to Ed Atkins and Amie Siegelto explore what the rewards and risks of assigning agency to objects may be, and how, or if, such new materialisms can be productive for making and thinking about art today.
