Exploring Resources and Reasoning Practices in Socioscientific System Modeling for Justice-Centered Science Education.

Integrating science education with social justice is vital for preparing students to critically address significant societal issues like climate change and pandemics. This study examines the effectiveness of socioscientific system modeling as a tool within Justice-Centered Science Pedagogy (JCSP) to enhance middle school students' understanding of social justice science issues. It focuses on how system modeling can scaffold students' reasoning about complex social systems, informed by their lived experiences, cultural backgrounds, and social identities.

A 32-Year-Old Male with Corneal Hydrops.

Case Presentation: A 32-year-old male with a history of left eye keratoconus presented to the emergency department with left eye pain and blurry vision for two days. Out of concern for corneal hydrops, ophthalmology was consulted, and the diagnosis was confirmed. Per ophthalmology recommendations, the patient was started on hypertonic saline and prednisolone eye drops and referred to a corneal specialist.

T. Howard Somervell: War Surgeon, Everest Pioneer, and Medical Missionary.

A full century has passed since George Leigh-Mallory and Andrew (Sandy) Irvine disappeared on the upper reaches of Mount Everest in June 1924. Theodore Howard Somervell (April 16, 1890-January 23, 1975), mountaineer, surgeon, and medical missionary, also was a key player in the 1924 expedition-as well as the 1922 Everest expedition where he was a member of the first ever team of climbers to break the 8000-m barrier. More commonly known as Howard or T.

Response strategies to acute and chronic environmental stress in the arctic breeding Lapland longspur (Calcarius lapponicus).

The potentially devastating effects of climate change have raised awareness of the need to understand how the biology of wild animals is influenced by extreme-weather events. We investigate how a wild arctic-breeding bird, the Lapland longspur (Calcarius lapponicus), responds to different environmental perturbations and its coping strategies. We explore the transcriptomic response to environmental adversity during the transition from arrival at the breeding grounds to incubation on the Arctic tundra.

Unraveling Hydration Shell Dynamics and Viscosity Effects Around Cyanamide Probes via 2D IR Spectroscopy.

Hydration dynamics and solvent viscosity play critical roles in the structure and function of biomolecules. An overwhelming body of evidence suggests that protein and membrane fluctuations are closely linked to solvent fluctuations. While extensive research exists on the use of vibrational probes to detect local interactions and solvent dynamics, fewer studies have explored how the behavior of these reporters changes in response to bulk viscosity.

Complexity demands more flexibility and the prefrontal cortex has an answer.

Cognitive flexibility allows us to adapt our behavior to keep up with a changing environment. In this issue of Neuron, Mugan and colleagues manipulate the complexity of an environment to demonstrate how the medial prefrontal cortex controls a cognitive flexibility circuit featuring the dorsolateral striatum and hippocampus.

A study of impulsivity and adverse childhood experiences in a population health setting.

As complex mental health traits and life histories are often poorly captured in hospital systems, the utility of using the Barratt Impulsivity Scale (BIS) and Adverse Childhood Experiences (ACEs) for assessing adult disease risks is unknown. Here, we use participants from the Healthy Nevada Project (HNP) to determine if two standard self-assessments could predict the incidence and onset of disease. We conducted a retrospective cohort study involving adult participants who completed the Behavioral and Mental Health Self-Assessment (HDSA) between September 2018 and March 2024.

Defining benefit: Clinically and biologically meaningful outcomes in the next-generation Alzheimer's disease clinical care pathway.

To understand the potential benefits of emerging Alzheimer's disease (AD) therapies within and beyond clinical trial settings, there is a need to advance current outcome measurements into meaningful information relevant to all stakeholders. The relationship between the impact on disease biology and clinically measurable outcomes in cognition, function, and behavior must be considered when defining the meaningful benefit of early AD therapies. In this review, we discuss: (1) the lack of consideration for biomarkers in the current concept of meaningfulness in AD; (2) the lack of gold standards for determining minimal biologically and clinically important differences (MBCIDs) in AD trials; (3) how the treatment benefits of disease-modifying treatments are cumulative and increase over time; and (4) the different concepts of meaningfulness among key stakeholders.

ThF thin films for solid-state nuclear clocks.

After nearly 50 years of searching, the vacuum ultraviolet Th nuclear isomeric transition has recently been directly laser excited and measured with high spectroscopic precision. Nuclear clocks based on this transition are expected to be more robust than and may outperform current optical atomic clocks. These clocks also promise sensitive tests for new physics beyond the standard model.

On the anatomy of acoustic emission.

Abrupt, local frictional fault failure comprises a displacement that is normally accompanied by acoustic emission (AE)-an impulsive elastic wave broadcast with an amplitude proportional to particle velocity. The aggregate of these displacements is the basic fault motion. In laboratory shear experiments, the examination of a sequence of laboratory earthquakes includes continuous measurements of fault motion and the associated AE that is broadcast.

A Conditional Indirect Effects Analysis of Intimate Partner Violence, Depression, Social Support, and Race With Alcohol Consumption among Postpartum Mothers.

Alcohol use and alcohol-related mortality for pregnant and postpartum women have increased, and there are racial disparities in both alcohol consumption and pregnancy outcomes. In addition, data indicate that women of Color are more likely to experience many forms of violence and face more adverse consequences from violence than non-Hispanic White women. Therefore, the current study examined how the direct and indirect pathways between intimate partner violence (IPV), depressive symptoms, and alcohol consumption are moderated by both social support and race among postpartum women.

A clinical examination of OPTIMAL theory application in people with multiple sclerosis: a proof-of-concept study and implications for rehabilitation practice.

We investigated the potential to improve motor learning and performance in people with multiple sclerosis (PwMS) with OPTIMAL theory conditions. OPTIMAL theory predicts that three main factors [i.e.

Racial disparities and socioeconomic factors associated with post-acute rehabilitation facility utilization among Nevadans with Alzheimer's disease and related disorders and extremity fractures: insights of age-friendly and dementia-friendly state planning in U.S.

Background: Falls and extremity fractures often occur in people living with Alzheimer's disease and related disorders (ADRD). In post-fracture care, these patients are cared for either at rehabilitation facilities or their homes. The coronavirus disease 2019 (COVID-19) pandemic limited the utilization of rehabilitation facilities.

Designing Highly Potent Side-Chain Lactam-Bridged Cyclic Competence-Stimulating Peptide-Based Quorum-Sensing Modulators in .

, a Gram-positive bacterium found in the oral microbiome, shows promise as an oral probiotic for preventing dental caries. It exhibits a reverse correlation with , a key caries-causing pathogen, likely due to its production of hydrogen peroxide, a process mediated by quorum sensing (QS). In this work, we set out to develop novel lactam-based cyclic analogues of the competence stimulating peptide (CSP) signal utilized by for QS activation.

Asymmetrical evolution of promoter methylation of mammalian genes after duplication.

Even though gene duplication is a key source of new genes and evolutionary innovation, it is unclear how duplicates survive the period immediately following gene duplication, in which both copies are functionally redundant. In the absence of epigenetic silencing, the abundance of the gene product would double after gene duplication, which would often have deleterious effects. However, recent duplicates exhibit low expression levels, which could be at least partially explained by high levels of promoter methylation.

Association Between Obesity and Intra-Abdominal Solid Organ Damage in Patients with Blunt Abdominal Trauma: A Cross-Sectional Study.

The global prevalence of obesity continues to rise. However, whether obesity affects the degree of intra-abdominal solid organ damage following blunt trauma remains unclear. This study aimed to investigate the correlation between obesity and intra-abdominal solid organ damage.

Going Above and Beyond: Bridging the Gap Between Equitable Outcomes and Procedural Fairness in Health Policy Administration.

Background/objectives: Public health administrators are entrusted to oversee the fair and efficient implementation of public health policy. Professional standards rooted in social justice add an additional ethical standard beyond what is required by procedural equality, reinforcing a service culture of creativity and doing more with less when resources are restrictive. This study explores this phenomenon within the context of government-subsidized opioid use disorder programming in Pennsylvania.

The Validation of the Sinclair Compassion Questionnaire (SCQ) and SCQ Short Form in an English-Speaking U.S. Population: A Patient-Reported Measure of Compassion in Healthcare.

Compassion is recognized as a key component of high-quality healthcare. The literature shows that compassion is essential to improving patient-reported outcomes and fostering health care professionals' (HCPs) response and resilience to burnout. However, compassion is inherently difficult to define, and a validated tool to reliably quantify and measure patients' experience of compassion in healthcare settings did not exist until recently.

Modeling Clustered DNA Damage by Ionizing Radiation Using Multinomial Damage Probabilities and Energy Imparted Spectra.

Simple and complex clustered DNA damage represent the critical initial damage caused by radiation. In this paper, a multinomial probability model of clustered damage is developed with probabilities dependent on the energy imparted to DNA and surrounding water molecules. The model consists of four probabilities: (A) direct damage of sugar-phosphate moieties leading to SSB, (B) OH radical formation with subsequent SSB and BD formation, (C) direct damage to DNA bases, and (D) energy imparted to histone proteins and other molecules in a volume not leading to SSB or BD.

Regular Family Meals Associated with Nutritional Status, Food Consumption, and Sedentary and Eating Behaviors of Brazilian Schoolchildren and Their Caregivers.

The influence of family meals on nutrition and health for families has been understudied, especially in low- and middle-income countries. We aimed to analyze associations between regular family meals and body mass index (BMI), food consumption, eating, and sedentary behaviors among Brazilian schoolchildren and their caregivers. A cross-sectional study was conducted with 1887 Brazilian schoolchildren aged 6-11 years and their caregivers.
