Data from: Changes in brain structure and function following exposure to oral LSD during adolescence: A multimodal MRI study
<p><em>Background</em>: LSD is a hallucinogen with complex neurobiological and behavioral effects. Underlying these effects are changes in brain neuroplasticity. This is the first study to follow the developmental changes in brain structure and function following LSD exposure in periadolescence. We hypothesized LSD given during a time of heightened neuroplasticity, particularly in the forebrain, would affect cognitive and emotional behavior and the associated underlying neuroanatomy and neurocircuitry. </p> <p><em>Methods:</em> Female and male mice were given vehicle, single, or multiple treatments of 3.3 µg of LSD by oral gavage starting on postnatal day 51. Between postnatal days 90-120 mice were imaged and tested for cognitive and motor behavior. MRI data from voxel-based morphometry, diffusion weighted imaging, and BOLD resting state functional connectivity were registered to a mouse 3D MRI atlas with 139 brain regions providing site-specific differences in global brain structure and functional connectivity between experimental groups.</p> <p><em>Results:</em> Motor behavior and cognitive performance were unaffected by periadolescent exposure to LSD. Differences across experimental groups in brain volume for any of the 139 brain areas were few in number and not focused on any specific brain region. Multiple exposures to LSD significantly altered gray matter microarchitecture across much of the brain. These changes were primary associated with the thalamus, sensory and motor cortices, and basal ganglia. The forebrain olfactory system and prefrontal cortex and hindbrain cerebellum and brainstem were unaffected. The functional connectivity between forebrain white matter tracts and sensorimotor cortices and hippocampus was reduced with multidose LSD exposure.</p> <p><em>Conclusion:</em> Does early exposure to LSD in periadolescence have lasting effects on brain development? There was no evidence of LSD having consequential effects on cognitive or motor behavior when animal were evaluated as young adults 90-120 days of age. Neither were there any differences in the volume of specific brain areas between experimental conditions. The pronounced changes in indices of anisotropy across much of the brain would suggest altered gray matter microarchitecture and neuroplasticity. The reduction in connectivity in forebrain white matter tracts with multidose LSD and consolidation around sensorimotor and hippocampal brain areas requires a battery of tests to understand the consequences of these changes on behavior.</p>
El Niño Enhances Exposure to Humid Heat Extremes with Regionally Varying Impacts during Eastern vs Central Pacific Events
<p><span>Humid heat extremes, characterized by high wet bulb temperature (Tw), pose significant health risks. While strong El Niño events are known to affect the frequency of extreme Tw days, the distinct impacts of Central Pacific (CP) and Eastern Pacific (EP) El Niño events remain understudied. Using a 12-member CMIP6 ensemble at discrete global warming targets (+1.5˚C, 2˚C, 3˚C, 4˚C), this study shows progressively enhanced humid heat exposure during EP events primarily in Mainland Southeast Asia, while South Asia experiences regionally opposing effects from EP and CP events. EP and CP events expose distinct, regionally varying areas to dangerous Tw, yet both significantly amplify population and area exposure to humid heat extremes at all global warming levels. This amplification surpasses the impact of an additional degree of global warming, highlighting El Niño’s compounding effect on heat stress threats across warmer climates.</span> <br><a name="_msocom_1"></a></p>
Raw and analyzed data for manuscript "In vitro eradication of Candida albicans biofilm through cold atmospheric plasma: Unravelling the interdependence of exposure and voltage in the antifungal mode of action."
<p><strong><span>Raw and analysed data for the manuscript, to be submitted to Journal of Infection and Public Health.</span></strong></p> <p> </p> <p><strong><span>Abstract:</span></strong></p> <p><strong><span>Introduction:</span></strong><span> Since <em>Candida spp</em>.</span> <span>is the fourth leading cause of healthcare-associated infections globally, the need for novel antifungal agents is increasing among scientists. This study investigates the potential of cold atmospheric plasma for <em>C. albicans</em> biofilm treatment. <strong>Methods:</strong> Our research focused on <em>in vitro</em> <em>C. albicans</em> biofilm response to varying parameters of plasma application, specifically the impact of treatment duration and input voltage. Evaluation of plasma influence on <em>C. albicans</em> was assessed with viability, membrane integrity, and oxidative stress measurements, along with observations of biofilm chemical composition and hyphae growth after plasma treatment. <strong>Results and Discussion:</strong> The higher plasma input voltage and increased exposure tme resulted in lower <em>C. albicans</em> cell viability, with complete reductions observed after 5 min plasma treatment duration across all input voltages tested. The effect of plasma treatment was further confirmed with a microscopic examination after BacLight<sup>® </sup>staining.</span> <span>Low (8 V) CAP exposure could potentially lead to a phenomenon known as hormesis, which was observed in <em>C. albicans</em> 24 h growth measurements. Additionally, intracellular oxidative stress assessment further proved that with prolonged treatment times, the intensity of oxidative stress, increased. Plasma treatment also affected the hyphae, which exhibited signs of contraction and compression. The chemical characteristics revealed that increasing plasma voltage and exposure time also have a distinguished impact on lipids, proteins, and carbohydrates, typical constituents of fungi biofilms. <strong>Conclusion:</strong> This study underscores the potential of plasma as a promising approach in combating <em>Candida spp</em>. biofilms, shedding light on the intricate dynamics of its impact on biofilm viability, morphology and composition.</span></p>

Sustainability-Based Long-Term Management of Bridges under Multi-Hazard Exposure
<p>Corresponding data set for Tran-SET Project No. 17STOKS01. Abstract of the final report is stated below for reference:</p> <p>"Bridges are under deterioration due to various mechanical and environmental stressors. Hydraulic-related hazards (e.g., flood and scour), aggressive environmental conditions, and seismic events (e.g., earthquake) are recognized as the most significant threats to the safety of bridges. In traditional risk assessment methods for structures susceptible to damage due to floods and other natural hazards (e.g., corrosion and seismic events), future hazard predictions are conducted using historic return periods and climate records. However, recent increase in flood intensity in central-southern states indicate that future hazard occurrence rate may not necessarily follow past trends. Accordingly, current design, assessment, and management methodologies should adapt to these changes in order to ensure the satisfactory performance of bridges under the combined or cumulative action of hazards. This project addresses this need by presenting a framework for risk quantification and optimum management of bridges susceptible to damage due to floods, flood induced scour, and other gradual deterioration mechanism (e.g., corrosion and fatigue). Downscaled climate data, adopted from the global climate models, are employed to predict future flood hazard at a given location. Probabilistic simulation is used to quantify the time-dependent failure probability, which subsequently helps quantify the long-term sustainability through the systematic integration of economic, social, and environmental metrics associated with bridge failures. These profiles can be next used to obtain optimum interventions required to extend the service life while maintaining the structural performance above prescribed thresholds."</p>
