Mechanically Robust Bismuth-Embedded Carbon Microspheres for Ultrafast Charging and Ultrastable Sodium-Ion Batteries.

Advancements in the development of fast-charging and long-lasting microstructured alloying anodes with high volumetric capacities are essential for enhancing the operational efficiency of sodium-ion batteries (SIBs). These anodes, however, face challenges such as declined cyclability and rate capability, primarily due to mechanical degradation reduced by significant volumetric changes (over 252%) and slow kinetics of sodium-ion storage. Herein, we introduce a novel anode design featuring densely packed bismuth (Bi) embedded within highly conductive carbon microspheres to overcome the aforementioned challenges.

Clinical criteria for limbic-predominant age-related TDP-43 encephalopathy.

Limbic predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) is highly prevalent in late life and a common co-pathology with Alzheimer's disease neuropathologic change (ADNC). LATE-NC is a slowly progressive, amnestic clinical syndrome. Alternatively, when present with ADNC, LATE-NC is associated with a more rapid course.

Plasmon Dynamics in Nanoclusters: Dephasing Revealed by Excited States Evaluation.

The photocatalytic efficiency of materials such as graphene and noble metal nanoclusters depends on their plasmon lifetimes. Plasmon dephasing and decay in these materials is thought to occur on ultrafast time scales, ranging from a few femtoseconds to hundreds of femtoseconds and longer. Here we focus on understanding the dephasing and decay pathways of excited states in small lithium and silver clusters and in plasmonic states of the π-conjugated molecule anthracene, providing insights that are crucial for interpreting optical properties and photophysics.

Identifying spatiotemporal patterns and drivers of fecal indicator bacteria in an urban lake for water quality assessment and management.

The designated uses of lakes connect individuals to the natural environment, but some can expose recreational users to pathogens associated with fecal contamination that cause waterborne illnesses. Routine monitoring of fecal indicators in surface waters helps identify and track sources of fecal contamination to protect public health. We examined fecal indicators ( and enterococci) and factors influencing recreational freshwater quality.

Molecular dynamics model of mechanophore sensors for biological force measurement.

Cellular forces regulate an untold spectrum of living processes, such as cell migration, gene expression, and ion conduction. However, a quantitative description of mechanical control remains elusive due to the lack of general, live-cell tools to measure discrete forces between biomolecules. Here we introduce a computational pipeline for force measurement that leverages well-defined, tunable release of a mechanically activated small molecule fluorophore.

Disentangling emotional source memory: a mega-analysis on the effects of emotion on item-context binding in episodic long-term memory.

Introduction: It has long been known that highly arousing emotional single items are better recollected than low arousing neutral items. Despite the robustness of this memory advantage, emotional arousing events may not always promote the retrieval of source details (i.e.

A case study: exploring the impact of 3D printed models on cognitive integration during clinical skills training.

Background: Cognitive integration occurs when trainees make conceptual connections between relevant knowledges and is known to improve learning. While several experimental studies have demonstrated how text and audio-visual instruction can be designed to enhance cognitive integration, clinical skills training in real-world contexts may require alternative educational strategies. Introducing three-dimensional (3D) printed models during clinical skills instruction may offer unique learning opportunities to support cognitive integration.

Cross-sectional evaluation of medical reversals among National Institute of Health guideline practices implemented during the COVID-19 pandemic: how often did experts err in a time of crisis?

Objective: The COVID-19 pandemic required the rapid and often widespread implementation of medical practices without robust data. Many of these practices have since been tested in large, randomised trials and were found to be in error. We sought to identify incorrect recommendations, or reversals, among National Institute of Health COVID-19 guidelines and Food and Drug Administration (FDA) approvals and authorisations.

Protocol for a multi-domain scoping review to identify measures of decision-making ability in an ageing population.

Introduction: Deficits in decision-making (DM) can lead to adverse outcomes across multiple domains such as financial management and medical care. By hindering such DM abilities, cognitive impairment (CI) often affects quality of life. Routine screening for CI, however, does not include systematic and comprehensive assessment of DM ability.

Rapid detection of RNase-based self-incompatibility in Lysimachia monelli (Primulaceae).

Premise: Primroses famously employ a system that simultaneously expresses distyly and filters out self-pollen. Other species in the Primulaceae family, including Lysimachia monelli (blue pimpernel), also express self-incompatibility (SI), but involving a system with distinct features and an unknown molecular genetic basis.

Methods: We utilize a candidate-based transcriptome sequencing (RNA-seq) approach, relying on candidate T2/S-RNase Class III and S-linked F-box-motif-containing genes and harnessing the unusual evolutionary and genetic features of SI, to examine whether an RNase-based mechanism underlies SI in L.

Helping Postdivorce Families Enhance Parent-Child Relationships: Clinical Applications to Effectively Help Divorced Parents Appropriately Communicate Their New Romance With Children.

Parental separation itself may be painful for both divorcing parents and children; however, this may not be the only stressful event in family structure among postdivorce families. Most divorced parents may start seeking a new romantic relationship before, during, and/or soon after their divorce or separation is finalized. Given that postdivorce dating may develop as a meaningful, stable, and supportive family tie, such as a stepparent-stepchild relationship, parents must communicate their new relationship with children if this relationship trajectory is anticipated.

Trends in Immunotherapy (IO) Use and Survival Among Patients With High-Incidence Stage IV Cancers Across the United States.

Background And Objectives: IO has transformed cancer management, but its adoption in advanced cancer patients varies by tumor type. With more Stage IV patients undergoing surgery, understanding site-specific outcomes in these challenging patients is essential. We aimed to evaluate IO use and survival trends for Stage IV cancer patients across high-incidence cancers in the US.

Assessment of a Single-Element Scanning System for Enhanced Photoacoustic Imaging of Brain Hemorrhage.

The use of photoacoustic brain imaging for hemorrhage detection holds significant clinical importance. This study focuses on the performance of sensitivity and detection capabilities of a single-element scanning system, considering the remarkable signal-to-noise ratio of photoacoustic signals generated by a single-element transducer. By employing blood vessel-like phantoms and ex vivo brain phantoms, we demonstrated the superior efficacy of the single-element scanning method over the transducer array system in the context of brain hemorrhage detection.

Social Determinants, Mental Well-Being, and Disrupted Life Transitions Among Young Adults with Disabling Mental Health Conditions.

This study sought to understand how young adults (age 18-25) with histories of mental health disorders are coping with disrupted transitions to adulthood during the COVID-19 pandemic. A cross-sectional web survey was conducted in March-June 2021 of 967 US young adults with pre-pandemic psychiatric disability to assess their current psychiatric status, interrupted transitions, and associations with social determinants including income, community participation, and social context. Mental health was assessed with the Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder Scale (GAD-7), and PTSD Checklist-Civilian Version.

Spectroscopic Methods for Detecting Conformational Changes During Sec18-Lipid Interactions.

Vacuole fusion is driven by SNARE proteins that require activation-or priming-by the AAA+ protein Sec18 (NSF) before they can bring membranes together and trigger the merger of two bilayers into a continuous membrane. Sec18 resides on vacuoles prior to engaging inactive cis-SNARE complexes through its interaction with the regulatory lipid phosphatidic acid (PA). Binding PA causes Sec18 to undergo large conformational changes that keeps it bound to the membrane, thus precluding its interactions with SNAREs.

Use of Bio-Layer Interferometry (BLI) to Measure Binding Affinities of SNAREs and Phosphoinositides.

Bio-Layer Interferometry (BLI) is a technique that uses optical biosensing to analyze interactions between molecules. The analysis of molecular interactions is measured in real-time and does not require fluorescent tags. BLI uses disposable biosensors that come in a variety of formats to bind different ligands including biotin, hexahistidine, GST, and the Fc portion of antibodies.

Molecular Dynamics Simulation for Membrane Fusion.

The soluble N-ethylmaleimide sensitive factor attachment protein receptor (SNARE) protein complex drives membrane fusion, and this process is further aided by accessory proteins, including complexin and α-synuclein. To understand the molecular mechanism underlying membrane fusion, we introduce an all-atom molecular dynamics (MD) simulation method. This method is used to understand and predict the conformations of protein and lipids, membrane geometry, and their interaction at femtosecond precision, by describing complex chemical systems with atomic models.

A Method for Imaging the Ischemic Penumbra with MRI using IVIM.
