Emerging evidence for the impact of Electric Vehicle sales on childhood asthma: Can ZEV mandates help?

Environ Res

January 2025

Department of Computer Science, University of Toronto, Toronto, Ontario, Canada; School of the Environment, University of Toronto, Toronto, Ontario, Canada. Electronic address:

Growing epidemiological studies indicate a significant fraction of asthma cases can be attributed to traffic-related air pollution (TRAP). Zero emission vehicle (ZEV) mandates-one of the most forward-looking climate policies in the United States-aim to reduce TRAP by mandating automakers to sell a certain fraction of Electric Vehicles (EVs) annually; however, their public health benefits are largely unknown. We conduct the screening step of the health impact assessment (HIA) of real-world EV sales to estimate the impact of ZEV mandates in reducing childhood asthma.

For a linking hypothesis in the visual world paradigm to clearly accommodate existing findings and make unambiguous predictions, it needs to be computationally implemented in a fashion that transparently draws the causal connection between the activations of internal representations and the measured output of saccades and reaching movements. Quantitatively implemented linking hypotheses provide an opportunity to not only demonstrate an existence proof of that causal connection but also to test the fidelity of the measuring methods themselves. When a system of interest is measured one way (e.

Comorbid diabetes and chronic kidney disease create a complex disease state with multi-faceted impacts on bone health, primarily reduced bone mass and tissue quality. To reduce fracture risk in this growing population, interventions are needed that target both bone mass and quality. Romosozumab (Romo) is an FDA-approved sclerostin inhibitor that has been shown to increase bone mass and strength in a murine model of combined diabetes and CKD (DKD), while Raloxifene (RAL) is a mild anti-resorptive used to treat osteoporosis that has also been shown to increase bone mechanical properties by increasing bone bound water content.

Intestinal ischemia-reperfusion (I/R) injury occurs under various surgical or disease conditions, where tissue hypoxia followed by reoxygenation results in the production of oxygen radicals and inflammatory mediators. These substances can target the endothelial barrier, leading to microvascular leakage. In this study, we induced intestinal I/R injury in mice by occluding the superior mesenteric artery, followed by removing the clamp to resume blood circulation.

D-allulose enhances lipid oxidation in HepG2 cells via peroxisome proliferator-activated receptor α (PPARα).

Biochim Biophys Acta Mol Cell Biol Lipids

January 2025

Division of Endocrinology, Diabetes, and Metabolism, Department of Medicine, University of Florida Jacksonville College of Medicine, Jacksonville, FL 32209, United States of America.

Lipid accumulation in hepatocytes in non-alcoholic steatohepatitis (NASH) is attributed partly to loss of insulin-responsiveness and/or an increased pro-inflammatory state. Since the rare sugar D-allulose has insulin mimetic and anti-inflammatory properties, its effects on lipid accumulation in liver-derived cells was tested. In HepG2 cells exposed to 200 μM oleic acid for 72 h, D-allulose treatment decreased intracellular lipid accumulation with an IC = 0.

Expanding the flooding in Landsat across tidal systems model to Landsat 5-9 imagery for long-term marsh inundation analysis.

Sci Total Environ

January 2025

Center for Geospatial Research, Department of Geography, University of Georgia, 210 Field St. Room 204, Athens, GA 30602, United States of America.

Tidal flooding can significantly impact vegetation pixel reflectance of coastal salt marshes, presenting a problem for remote sensing studies of these highly productive ecosystems. The current study aimed to spatially and temporally expand our previously developed Flooding in Landsat Across Tidal Systems (FLATS) model to detect and analyze the long-term changes in flooded marsh pixels in Landsat 5-9 imagery. As the FLATS index is only calibrated for Landsat 8, our goal was to expand the use of FLATS to a greater range of Landsat imagery and facilitate the masking of flooded pixels in long-term time series of vegetation indices.

Objectives: Thrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathy associated with severe deficiency in ADAMTS13. ADAMTS13 deficiency may be secondary to absent or dysfunctional protein production due to mutations in the ADAMTS13 gene (congenital TTP) or autoantibody-mediated clearance and/or inhibition (immune-mediated TTP). This autoimmunity may, albeit rarely, occur secondary to certain medications (eg, ticlopidine).
