From a mother's point of view: Psycho-social predictors of maternal monitoring strategy and adolescents' electronic media use.

Introduction: As early adolescents have limited capacities for self-regulating electronic media use (EMU), parental monitoring is needed. However, research has shown that parents do not exert much monitoring over their children's EMU. A theory-based approach may help to identify key predictors of parental monitoring and its effects on adolescents' EMU.

Cultivation and Enabling Effects of Social Support and Self-Efficacy in Parent-Child Dyads.

Background: There are two alternative mechanisms, elucidating the reciprocal relationship between self-efficacy and social support when explaining health outcomes: self-efficacy beliefs may operate as the establisher of social support (the cultivation model) or social support may enable the formation of self-efficacy beliefs (the enabling model).

Purpose: In line with the cultivation hypothesis, it was tested if self-efficacy (measured in parents and children) would indirectly predict parental and child moderate-to-vigorous physical activity (MVPA), via the mediator, social support (parent-provided, child-received). In line with the enabling hypothesis, it was tested if social support would predict MVPA indirectly, via the mediator, self-efficacy.

Holistic numerical calibration of the iMESA electrostatic analyzer.

A drifted Maxwellian velocity distribution is the most common model used to interpret the data from low-energy charged-particle instruments onboard spacecraft that are used to investigate the ambient plasma environment in the low Earth orbit (LEO). An original method is presented for determining the flow parameters (density, temperature, and flow energy) of such a distribution from the output of the integrated miniaturized electrostatic analyzer, which has been successfully flown on several LEO missions. Rather than attempting to deconvolve from the on-orbit data the analyzer's response to an ideal, monoenergetic input, numerical simulation is used to predict and parameterize the response of the device to an input distribution that includes an isotropic, non-zero temperature, yielding a straightforward method for extracting the flow parameters from the spacecraft data.

Terror Management Theory and the COVID-19 Pandemic.

Terror management theory is focused on the role that awareness of death plays in diverse aspects of life. Here, we discuss the theory's implications for understanding the widely varying ways in which people have responded to the COVID-19 pandemic. We argue that regardless of whether one consciously believes that the virus is a major threat to life or only a minor inconvenience, fear of death plays an important role in driving one's attitudes and behavior related to the virus.

Examining mental health stigma in a first-year seminar for student veterans.

To examine perceptions of mental health stigma among first-year student service members/veterans (SSM/Vs). 107 SSM/Vs enrolled in a first-semester seminar completed a pre- and post-test measuring five constructs; 1) stigma toward mental health in the military, 2) academic readiness, 3) mental health stigma in college, 4) connection to campus, and 5) resiliency. : Data were analyzed using paired samples t-tests to measure growth on the scales of interest, along with a multiple regression analysis to establish predictors of growth.

The integrated miniaturized electrostatic analyzer: A space plasma environment sensor.

The integrated Miniaturized Electrostatic Analyzer (iMESA) was a satellite-based ionospheric sensor that operated on NASA's Space Test Program Satellite (STPSat-3) from December 2013 to July 2019. The instrument's scientific objective was to (1) measure the plasma density in low Earth orbit, (2) measure the plasma temperature in low Earth orbit, and (3) quantify the spacecraft potential with respect to the ambient plasma potential in the ionosphere. iMESA sampled the ionosphere every 10 s by measuring the ion current density through the ESA as a result of the motion of the spacecraft through the plasma.

An Empirical Evaluation of the Alternative Model of Personality Disorders in Later Life.

Personality disorders (PDs) in the () are conceptualized as distinct clinical syndromes. However, debate persists about the clinical utility of this categorical model, with many researchers supporting a dimensional model that focuses on pathological personality traits and personality dysfunction. This model was published in Section III of and named the Alternative Model of Personality Disorders (AMPD).

Applying the social ecological framework to enhance wellness for student veterans.

To increase campus-wide wellness for student service members/veterans (SSM/Vs), student services professionals, healthcare providers, and faculty collaborated to implement the Social Ecological Framework (SEF) over a three-year project.One thousand six hundred and seventy eight SSM/Vs enrolled at a medium-sized doctoral granting institution with high-research activity (R2). SSM/Vs were directly and indirectly impacted through a series of initiatives, including stigma reduction efforts, wellness promotion, faculty training, therapeutic services, and peer-advising.

Reliable change in neuropsychological test scores is associated with brain atrophy in older adults.

The reliable change index (RCI) is a commonly used method for interpreting change in neuropsychological test scores over time. However, the RCI is a psychometric method that, to date, has not been validated against neuroanatomical changes. Longitudinal neuroimaging and neuropsychological data from baseline and one-year follow-up visits were retrieved from the Alzheimer's Disease Neuroimaging Initiative (ADNI) database.

Exploiting Unique Alignment of Cobalt Ferrite Nanoparticles, Mild Hyperthermia, and Controlled Intrinsic Cobalt Toxicity for Cancer Therapy.

Nanoparticle-based magnetic hyperthermia is a well-known thermal therapy platform studied to treat solid tumors, but its use for monotherapy is limited due to incomplete tumor eradication at hyperthermia temperature (45 °C). It is often combined with chemotherapy for obtaining a more effective therapeutic outcome. Cubic-shaped cobalt ferrite nanoparticles (Co-Fe NCs) serve as magnetic hyperthermia agents and as a cytotoxic agent due to the known cobalt ion toxicity, allowing the achievement of both heat and cytotoxic effects from a single platform.

Assessment of Anxiety in Long-Term Care Residents: Issues and Strategies.

The experience of clinically significant anxiety and anxiety disorders represent significant and often debilitating problems for many residents in long-term care (LTC) settings. However, anxiety problems often go undetected and untreated in this growing population. The purposes of this paper are to examine the prevalence and impact of anxiety problems among residents in LTC facilities, describe the efficacy of the current instruments that are used to detect anxiety in these settings, and provide clinical guidance for the thorough assessment of anxiety.

Lipid membrane templated misfolding and self-assembly of intrinsically disordered tau protein.

The aggregation of the intrinsically disordered tau protein into highly ordered β-sheet-rich fibrils is implicated in the pathogenesis of a range of neurodegenerative disorders. The mechanism of tau fibrillogenesis remains unresolved, particularly early events that trigger the misfolding and assembly of the otherwise soluble and stable tau. We investigated the role the lipid membrane plays in modulating the aggregation of three tau variants, the largest isoform hTau40, the truncated construct K18, and a hyperphosphorylation-mimicking mutant hTau40/3Epi.

Do Parent-Child Dyads with Excessive Body Mass Differ from Dyads with Normal Body Mass in Perceptions of Obesogenic Environment?

Background: This study addressed differences between parent-child dyads with excessive body mass (overweight or obesity) and dyads with normal body mass in obesity determinants, derived from social-ecological models. It was hypothesized that parents and their 5-11 years-old children with excessive body mass would (1) report lower availability of healthy food at home, (2) perceive fewer school/local community healthy eating promotion programs, (3) report lower persuasive value of food advertising.

Methods: Data were collected twice (T1, baseline; T2, 10-month follow-up), including = 129 parent-child dyads with excessive body mass and = 377 parent-child dyads with normal body mass.

TIRF Microscope Image Sequences of Fluorescent IgE-FcεRI Receptor Complexes inside a FcεRI-Centric Synapse in RBL-2H3 Cells.

Total internal reflection fluorescence (TIRF) microscope image sequences are commonly used to study receptors in live cells. The dataset presented herein facilitates the study of the IgE-FcεRI receptor signaling complex (IgE-RC) in rat basophilic leukemia (RBL-2H3) cells coming into contact with a supported lipid bilayer with 25 mol% N-dinitrophenyl-aminocaproyl phosphatidylethanolamine, modeling an immunological synapse. TIRF microscopy was used to image IgE-RCs within this FcεRI-centric synapse by loading RBL-2H3 cells with fluorescent anti-dinitrophenyl (anti-DNP) immunoglobulin E (IgE) in suspension for 24 h.

A Cross-sectional Study of Hospital Performance on ICU Utilization Practices for Patients with Chronic Obstructive Pulmonary Disease.

Purpose: Intensive care unit (ICU) resources are a costly but effective commodity used in the management of critically ill patients with chronic obstructive pulmonary disease (COPD). ICU admission decisions are determined by patient diagnosis and severity of illness, but also may be affected by hospital differences in quality and performance. We investigate the variability in ICU utilization for patients with COPD and its association with hospital characteristics.

The intergenic small non-coding RNA ittA is required for optimal infectivity and tissue tropism in Borrelia burgdorferi.

Post-transcriptional regulation via small regulatory RNAs (sRNAs) has been implicated in diverse regulatory processes in bacteria, including virulence. One class of sRNAs, termed trans-acting sRNAs, can affect the stability and/or the translational efficiency of regulated transcripts. In this study, we utilized a collaborative approach that employed data from infection with the Borrelia burgdorferi Tn library, coupled with Tn-seq, together with borrelial sRNA and total RNA transcriptomes, to identify an intergenic trans-acting sRNA, which we designate here as ittA for infectivity-associated and tissue-tropic sRNA locus A.

Bose-Einstein condensation of quasiparticles by rapid cooling.

The fundamental phenomenon of Bose-Einstein condensation has been observed in different systems of real particles and quasiparticles. The condensation of real particles is achieved through a major reduction in temperature, while for quasiparticles, a mechanism of external injection of bosons by irradiation is required. Here, we present a new and universal approach to enable Bose-Einstein condensation of quasiparticles and to corroborate it experimentally by using magnons as the Bose-particle model system.

Artifact-free whole-slide imaging with structured illumination microscopy and Bayesian image reconstruction.

Background: Structured illumination microscopy (SIM) is a method that can be used to image biological samples and can achieve both optical sectioning and super-resolution effects. Optimization of the imaging set-up and data-processing methods results in high-quality images without artifacts due to mosaicking or due to the use of SIM methods. Reconstruction methods based on Bayesian estimation can be used to produce images with a resolution beyond that dictated by the optical system.

Impact of end-of-life planning on surrogate decision-maker anxiety in the US.

At the end of life, hospice patients frequently rely on surrogate decision makers (SDMs) for healthcare decisions, which creates anxiety among SDMs. This project evaluated whether an educational intervention to create a plan of care for hospice patients would reduce anxiety among SDMs. Before the intervention, immediately after the intervention, and 2 weeks following the intervention SDM anxiety was measured with the Geriatric Anxiety Scale, State Trait Anxiety Inventory-State Anxiety Scale, and one question about decision-making anxiety.

Parental Depression Predicts Child Body Mass via Parental Support Provision, Child Support Receipt, and Child Physical Activity: Findings From Parent/Caregiver-Child Dyads.

Objective: Although there is substantial evidence corroborating the within-individual associations between depression, social support, moderate-to-vigorous physical activity (MVPA), and body mass, much less is known about across-individual associations. This study investigated the indirect associations between parental depression and objectively measured body mass in children. In particular, it was hypothesized that higher levels of parental depression (measured at Time 1, T1) would explain higher levels of child body mass in children (assessed at Time 2, T2), via three mediators, namely parental reports of provision of MVPA support (T1), child reports of receipt of MVPA support (T1), and child MVPA (T2).

Relationships between pathological narcissism and maladaptive personality traits among older adults.

The Pathological Narcissism Inventory (PNI) is a measure of narcissism, with two domains of Vulnerability and Grandiosity, that has limited evidence of validity among older adults. Subsequently, the objective of the present study was to examine relationships between the PNI and measures of diverse pathological personality features. Participants consisted of 125 community-dwelling older adults ( age = 71.

Menstrual and reproductive characteristics and breast cancer risk by hormone receptor status and ethnicity: The Breast Cancer Etiology in Minorities study.

We pooled multiethnic data from four population-based studies and examined associations of menstrual and reproductive characteristics with breast cancer (BC) risk by tumor hormone receptor (HR) status [defined by estrogen receptor (ER) and progesterone receptor (PR)]. We estimated odds ratios and 95% confidence intervals using multivariable logistic regression, stratified by age (<50, ≥50 years) and ethnicity, for 5,186 HR+ (ER+ or PR+) cases, 1,365 HR- (ER- and PR-) cases and 7,480 controls. For HR+ BC, later menarche and earlier menopause were associated with lower risk in non-Hispanic whites (NHWs) and Hispanics, and higher parity and longer breast-feeding were associated with lower risk in Hispanics and Asian Americans, and suggestively in NHWs.
