Constructing Highly Porous Low Iridium Anode Catalysts Via Dealloying for Proton Exchange Membrane Water Electrolyzers.

Iridium (Ir) is the most active and durable anode catalyst for the oxygen evolution reaction (OER) for proton exchange membrane water electrolyzers (PEMWEs). However, their large-scale applications are hindered by high costs and scarcity of Ir. Lowering Ir loadings below 1.

Alternative splicing of transcript mediates the response of circadian clocks to temperature changes.

Circadian clocks respond to temperature changes over the calendar year, allowing organisms to adjust their daily biological rhythms to optimize health and fitness. In , seasonal adaptations are regulated by temperature-sensitive alternative splicing (AS) of () and () genes that encode key transcriptional repressors of clock gene expression. Although () gene encodes the critical activator of circadian gene expression, AS of its transcripts and its potential role in temperature regulation of clock function have not been explored.

Multilevel associations of peer cognitive factors and adolescent cannabis use in a legal recreational cannabis region.

Background: Cannabis use can have unintended, harmful consequences for adolescents, a developmental group that struggles with heightened pressure to align with peer attitudes and behaviors. The role of social-cognitive factors in shifting cannabis use dynamics remains under explored, particularly in states where recreational cannabis use is legal.

Objectives: The present study examined multilevel longitudinal associations between resistance to peer influence, peer norms, and adolescent cannabis use over the course of 12 months.

Tilting the Scales toward EGFR Mutant Selectivity: Expanding the Scope of Bivalent "Type V" Kinase Inhibitors.

Binding multiple sites within proteins with bivalent compounds is a strategy for developing uniquely active agents. A new class of dual-site inhibitors has emerged targeting the epidermal growth factor receptor (EGFR) anchored to both the orthosteric (ATP) and allosteric sites. Despite proof-of-concept successes, enabling selectivity against oncogenic activating mutations has not been achieved and classifying these inhibitors among kinase inhibitors remains underexplored.

Assessment of Linear and Cyclic Peptides' Immobilization onto Cross-Linked, Poly(vinyl alcohol)/Cellulose Nanocrystal Nanofibers Electrospun over Quartz Crystal Microbalances with Dissipation Sensors.

Immobilization of peptides onto nanofiber dressings holds significant potential for chronic wound treatment. However, it is necessary to understand the adsorptive capacity of the produced substrates and the binding affinity of the peptides to determine the interface success. This study aims at exploring for the first time the influence of electrospun poly(vinyl alcohol)-based nanofibers on the adsorption of a cyclic peptide, Tiger 17, and of a linear peptide, Pexiganan, using quartz crystal microbalance with dissipation monitoring (QCM-D).

The mutually reinforcing dynamics between pain and stress: mechanisms, impacts and management strategies.

While distinct, pain and stress share complex biological and psychological mechanisms that-despite their protective functions-can lead to clinically maladaptive changes requiring therapeutic intervention when they recur or persist. Recognized as "worldwide epidemics" of modern life, both conditions significantly affect an individual's quality of life, functioning, and well-being; without timely intervention, they can become chronic, leading to substantial economic costs via healthcare expenses, lost wages, and reduced productivity. Evidence suggests that pain and stress not only feed into but exacerbate each other through a "vicious cycle," driven by overlapping physiological, cognitive, and social mechanisms, indicating mutually reinforcing dynamics between pain and stress.

Estradiol impacts Müller glia and endothelial cell responses in hyperglycemic microenvironments with advanced glycation end products.

Diabetic retinopathy is a leading cause of vision loss in working adults, with disproportionate impact on women with lowered estrogen. Sex hormones and their receptors are significant to neuroprotection of the inner blood-retinal barrier (iBRB), a tissue that regulates transport across the neuroretina and vasculature. Moreover, high glucose levels in diabetes lead to the formation of advanced glycation end products (AGEs), which promote inflammation and iBRB breakdown to result in vision loss.

A comparison of scalable routine clinical materials and observer ratings to assess CBT fidelity.

Decades of research have demonstrated the efficacy of cognitive behavioral therapies (CBTs) for a wide variety of psychiatric diagnoses, resulting in the inclusion of CBT as a first-line evidence-based practice (EBP) in treatment guidelines for mood and anxiety disorders. However, some research suggests that many providers do not implement EBPs as intended. Ongoing quality monitoring is needed to support EBP implementation and sustainability, but "gold standard" fidelity monitoring (e.

N-cadherin antagonism is bronchoprotective in severe asthma models.

Severe asthma induces substantial mortality and chronic disability due to intractable airway obstruction, which may become resistant to currently available therapies including corticosteroids and β-adrenergic agonist bronchodilators. A key effector of these changes is exaggerated airway smooth muscle (ASM) cell contraction to spasmogens. No drugs in clinical use effectively prevent ASM hyperresponsiveness in asthma across all severities.

Serious Game-Based Balance Training with Augmented Kinesthetic Feedback Enhances Aspects of Postural Control in Poststroke Patients: A Randomized Clinical Trial.

Poststroke hemiparesis presents with motor asymmetry and decreased postural control leading to functional limitations. Serious games (SG) for balance rehabilitation of people with stroke may improve motor recovery, and the visual and auditory feedback provided by the SGs helps to explain the therapeutic benefits. However, the contribution of SG combined with kinesthetic and verbal cues during balance training has not been investigated.

Investigating the Mechanism of Neurotoxic Effects of PFAS in Differentiated Neuronal Cells through Transcriptomics and Lipidomics Analysis.

Per- and polyfluorinated alkyl substances (PFAS) are pervasive environmental contaminants that bioaccumulate in tissues and pose risks to human health. Increasing evidence links PFAS to neurodegenerative and behavioral disorders, yet the underlying mechanisms of their effects on neuronal function remain largely unexplored. In this study, we utilized SH-SY5Y neuroblastoma cells, differentiated into neuronal-like cells, to investigate the impact of six PFAS compounds─perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), perfluorodecanoic acid (PFDA), perfluorodecanesulfonic acid (PFDS), 8:2 fluorotelomer sulfonate (8:2 FTS), and 8:2 fluorotelomer alcohol (8:2 FTOH)─on neuronal health.

Background: Accurately capturing individuals' experiences with greenspace at ground-level can provide valuable insights into their impact on children's health. However, most previous research has relied on coarse satellite-based measurements.

Methods: We utilized CVH and residential address data from Project Viva, a US-based pre-birth cohort, tracking participants from mid-childhood to late adolescence (2007-21).

Müller Glia Co-Regulate Barrier Permeability with Endothelial Cells in an Vitro Model of Hyperglycemia.

Diabetic retinopathy is a complex, microvascular disease that impacts millions of working adults each year. High blood glucose levels from Diabetes Mellitus lead to the accumulation of advanced glycation end-products (AGEs), which promote inflammation and the breakdown of the inner blood retinal barrier (iBRB), resulting in vision loss. This study used an in vitro model of hyperglycemia to examine how endothelial cells (ECs) and Müller glia (MG) collectively regulate molecular transport.
