COVID-19 Misperceptions and Masking Compliance: A Support Marshaling Analysis.

Misperceptions strongly influence the extent to which individuals comply with preventative measures. Social support from others, particularly given widespread mistrust in news media among those holding misperceptions, plays an important role in shaping compliance with preventative measures. The impact of social support, however, is not straightforward and not all support results in greater compliance.

Functional dynamics of G protein-coupled receptors reveal new routes for drug discovery.

G protein-coupled receptors (GPCRs) are the largest human membrane protein family that transduce extracellular signals into cellular responses. They are major pharmacological targets, with approximately 26% of marketed drugs targeting GPCRs, primarily at their orthosteric binding site. Despite their prominence, predicting the pharmacological effects of novel GPCR-targeting drugs remains challenging due to the complex functional dynamics of these receptors.

UNDERSTANDING DRUNKOREXIA BEHAVIORS AMONG COLLEGE STUDENTS USING THE THEORY OF PLANNED BEHAVIOR.

Drunkorexia refers to high-risk behaviors that involve the intersection of disordered eating behaviors and risky alcohol consumption. This study utilized the extended Theory of Planned Behavior (TPB) to identify potential psychosocial factors that contribute to drunkorexia among students (484 undergraduate students) from a midwestern Mid-sized university. This cross-sectional study used online surveys designed to measure various drunkorexia-related behaviors including alcohol consumption, calorie restriction, excessive exercise, and purging utilizing antecedents of the TPB.

Depressive Symptoms and Violence Perpetration: Examining the Moderating Influence of Reward Sensitivity and Emotional Reactivity in Community Adults at Elevated Risk for Violent Behavior.

There is growing interest in understanding whether, and under what circumstances, depression confers risk for violence perpetration. To address these questions, we examined whether major depressive disorder (MDD) symptoms correlated with violence perpetration beyond co-occurring externalizing psychopathology, and whether individual differences in reward and emotional reactivity modified depression-violence associations. In a sample of 480 community adults ( =32.

Temperature, violent crime, climate change, and vulnerability factors in 44 United States cities.

Biological and psychological theories suggest complex impacts of heat on aggression and violence. Most previous studies considered temporal intervals of months to years and assumed linear associations. Evidence is needed on daily impacts of temperature on crime, applying non-linear models across different locations.

A Novel, Site-Specific N-Linked Glycosylation Model Provides Mechanistic Insights Into the Process-Condition Dependent Distinct Fab and Fc Glycosylation of an IgG1 Monoclonal Antibody Produced by CHO VRC01 Cells.

The CHO VRC01 cell line produces an anti-HIV IgG1 monoclonal antibody containing N-linked glycans on both the Fab (variable) and Fc (constant) regions. Site-specific glycan analysis was used to measure the complex effects of cell culture process conditions on Fab and Fc glycosylation. Experimental data revealed major differences in glycan fractions across the two sites.

Infant With Beckwith-Wiedemann Requiring Transplant for Hepatic Mesenchymal Hamartoma.

Background: Liver transplantation for unresectable, benign hepatic lesions is rare. Hepatic mesenchymal hamartomas (HMH) are benign, cystic tumors that arise mostly in pediatric populations and can cause compressive symptoms. HMH is rarely associated with placental mesenchymal dysplasia (PMD) and Beckwith-Wiedemann syndrome (BWS).

Mechanical Deformation Behavior of Polymer Blend Thin Films.

Examining the mechanical properties of polymer thin films is crucial for high-performance applications such as displays, coatings, sensors, and thermal management. It is important to design thin film microstructures that excel in high-demand situations without compromising mechanical integrity. Here, a polymer blend of polystyrene (PS) and polyisoprene (PI) is used as a model to explore microscale deformation behavior under uniaxial mechanical testing.

A brief report on biomarkers of cellular senescence associated with liver frailty and length of stay in liver transplantation.

The proportion of older individuals needing liver transplantation is growing, resulting in an increasingly frail patient population. Frailty constitutes a constellation of cognitive and physical symptoms associated with aging and increases the risk of morbidity and mortality. Senescence is a programmed cell fate in response to stress implicated in causing frailty, age-related diseases, and aging itself.

Effects of anatomy and head motion on spatial patterns of deformation in the human brain.

Purpose: To determine how the biomechanical vulnerability of the human brain is affected by features of individual anatomy and loading.

Methods: To identify the features that contribute most to brain vulnerability, we imparted mild harmonic acceleration to the head and measured the resulting brain motion and deformation using magnetic resonance elastography (MRE). Oscillatory motion was imparted to the heads of adult participants using a lateral actuator (n = 24) or occipital actuator (n = 24) at 20 Hz, 30 Hz, and 50 Hz.

Soil bacterial communities in urban deciduous forests are filtered by site identity, soil chemistry, and shrub presence.

Urban forest soils are complex environments subjected to various stressors that alter chemical and microbial properties. To understand soil chemistry and bacterial community patterns in urban forest soils with respect to site identity and multiflora rose (Rosa multiflora) invasion, soils were collected from beneath R. multiflora, native spice bush (Lindera benzoin), and uncovered ground in three forests in Newark, Delaware.

Single unit-derived connectivity networks in tuberous sclerosis complex reveal propensity for network hypersynchrony driven by tuber-tuber interactions.

Network hypersynchrony is emerging as an important system-level mechanism underlying seizures, as well as cognitive and behavioural impairments, in children with structural brain abnormalities. We investigated patterns of single neuron action potential behaviour in 206 neurons recorded from tubers, transmantle tails of tubers and normal looking cortex in 3 children with tuberous sclerosis. The patterns of neuronal firing on a neuron-by-neuron (autocorrelation) basis did not reveal any differences as a function of anatomy.

Adolescent circadian rhythm disruption increases reward and risk-taking.

Introduction: Circadian rhythm disturbances have long been associated with the development of psychiatric disorders, including mood and substance use disorders. Adolescence is a particularly vulnerable time for the onset of psychiatric disorders and for circadian rhythm and sleep disruptions. Preclinical studies have found that circadian rhythm disruption (CRD) impacts the brain and behavior, but this research is largely focused on adult disruptions.

Factors Associated with Pediatric Drowning-Associated Lung Injury.

Objective: To identify risk factors for clinically-important drowning-associated lung injury (ciDALI) in children.

Study Design: This was a cross-sectional study of children (0 through18 years) who presented to 32 pediatric emergency departments (EDs) from 2010 through 2017. We reviewed demographics, comorbidities, prehospital data, chest radiographs reports, and ED course from emergency medical services, medical, and fatality records.

Electrochemical Synthesis of Zeolite Coatings with Controlled Crystal Polymorphism and Self-Regulating Growth.

Zeolite coatings are studied as molecular sieves for membrane separation, membrane reactors, and chemical sensor applications. They are also studied as anticorrosive films for metals and alloys, antimicrobial and hydrophobic films for heating, ventilation, and air conditioning, and dielectrics for semiconductor applications. Zeolite coatings are synthesized by hydrothermal, ionothermal, and dry-gel conversion approaches, which require high process temperatures and lengthy times (ranging from hours to days).

Experimental Full-volume Airway Approximation for Assessing Breath-dependent Regional Aerosol Deposition.

Modeling aerosol dynamics in the airways is challenging, and most modern personalized tools consider only a single inhalation maneuver through less than 10% of the total lung volume. Here, we present an modeling pipeline to produce a device that preserves patient-specific upper airways while approximating deeper airways, capable of achieving total lung volumes over 7 liters. The modular system, called TIDAL, includes tunable inhalation and exhalation breathing capabilities with resting flow rates up to 30 liters per minute.

Assessment of varus thrust using inertial measurement units.

Background: Varus thrust is common in those with knee osteoarthritis. Varus thrust is traditionally identified with visual analysis or motion capture, methods that are either dichotomous or limited to the laboratory setting. Inertial measurement unit data has been found to correlate with motion capture measures of varus thrust in those with severe knee osteoarthritis, allowing for a quantitative and accessible way of measuring varus thrust.

Cross-species regulatory network analysis identifies FOXO1 as a driver of ovarian follicular recruitment.

The transcriptional regulation of gene expression in the latter stages of follicular development in laying hen ovarian follicles is not well understood. Although differentially expressed genes (DEGs) have been identified in pre-recruitment and pre-ovulatory stages, the master regulators driving these DEGs remain unknown. This study addresses this knowledge gap by utilizing Master Regulator Analysis (MRA) combined with the Algorithm for the Reconstruction of Accurate Cellular Networks (ARACNe) for the first time in laying hen research to identify master regulators that are controlling DEGs in pre-recruitment and pre-ovulatory phases.

School and meal characteristics associated with plate waste in K-12 cafeterias in the United States.

Food wasted in primary and secondary education institutions creates nutritional losses, financial inefficiencies, and environmental degradation. While there is some evidence of how particular interventions within schools may influence the amount of waste created, there is little recent information about typical levels of food waste generated in U.S.

Youth Soccer Heading Exposure and Its Effects on Clinical Outcome Measures.

Purposeful heading, in which players may use their heads to advance the ball in play, is a unique part of soccer. Clinical outcome measures used to aid in the diagnosis of a concussion have long been a cornerstone of the contemporary measurements associated with the short- and long-term effects of monitoring repetitive head impacts (RHI) and soccer heading exposure. The effects of RHI in the youth population are still unknown, therefore, the purpose of this study was to examine if heading exposure is predictive of changes in self-reported symptoms, neurocognitive functioning, gait, and balance in female youth soccer players over the course of one soccer season.
