Unilateral Versus Bilateral Endoscopic Resection of Olfactory Neuroblastoma: Pooled Analysis From Prospective and Retrospective Multicenter Data.

Background: Olfactory neuroblastoma (ONB) is a rare sinonasal malignancy primarily treated with surgery. For tumors arising from the olfactory area, traditional treatment involves transcribriform resection of the anterior cranial fossa. Surgery can be performed with unilateral or bilateral resection depending on extent of involvement; however, there are currently no studies comparing outcomes between the two.

Reversal of inflammatory reprogramming by vasodilator agents in pulmonary hypertension.

Background: Pulmonary arterial hypertension (PAH) is a deadly disease without effective non-invasive diagnostic and prognostic testing. It remains unclear whether vasodilators reverse inflammatory activation, a part of PAH pathogenesis. Single-cell profiling of inflammatory cells in blood could clarify these PAH mechanisms.

Combining Fourier Transform Ion Mobility with Charge Detection Mass Spectrometry for the Analysis of Multimeric Protein Complexes.

Charge detection mass spectrometry (CDMS) allows direct mass measurement of heterogeneous samples by simultaneously determining the charge state and the mass-to-charge ratio (/) of individual ions, unlike conventional MS methods that use large ensembles of ions. CDMS typically requires long acquisition times and the collection of thousands of spectra, each containing tens to hundreds of ions, to generate sufficient ion statistics, making it difficult to interface with the time scales of online separation techniques such as ion mobility. Here, we demonstrate the application of Fourier transform multiplexing and drift tube ion mobility joined with Orbitrap-based CDMS for the analysis of multimeric protein complexes.

Daily sleep and physical activity from accelerometry in adults: Temporal associations and lag effects.

Objectives: Insufficient sleep is linked to various health issues, while physical activity is a protective measure against chronic diseases. Despite the importance of sleep and physical activity for supporting public health, there remains scant research investigating daily and cumulative associations between objectively measured physical activity and sleep. Understanding the associations of physical activity and sleep behaviors over multiple days may inform the efficacy of interventions to synergistically support both behaviors.

Modeling, synthesis and cell-based evaluation of pyridine-substituted analogs of CD3254 and fluorinated analogs of CBt-PMN as novel therapeutics.

Six pyridine analogs of (E)-3-(3-(1,2,3,4-tetrahydro-1,1,4,4,6-pentamethylnaphthalen-7-yl)-4-hydroxyphenyl)acrylic acid-or CD3254 (11)-in addition to two novel analogs of 1-(3,5,5,8,8-pentamethyl-5,6,7,8-tetrahydronaphthalen-2-yl)-1H-benzo[d][1,2,3]triazole-5-carboxylic acid (CBt-PMN or 23) were prepared and evaluated for selective retinoid-X-receptor (RXR) agonism alongside bexarotene (1), an FDA-approved drug for cutaneous T-cell lymphoma (CTCL). Treatment with 1 often elicits side-effects by disrupting or provoking other RXR-dependent nuclear receptors and cellular pathways. All analogs were assessed through modeling for their ability to bind RXR and then evaluated in human colon and kidney cells employing an RXR-RXR mammalian-2-hybrid (M2H) system and in an RXRE-controlled transcriptional assay.

Estimating realized relatedness in free-ranging macaques by inferring identity-by-descent segments.

Biological relatedness is a key consideration in studies of behavior, population structure, and trait evolution. Except for parent-offspring dyads, pedigrees capture relatedness imperfectly. The number and length of identical-by-descent DNA segments (IBD) yield the most precise relatedness estimates.

CBTI implementation outcomes: one-year follow up.

Insomnia is a common and debilitating disorder that is often undiagnosed and untreated. Cognitive behavioral therapy for insomnia (CBTI) is the first-line treatment for insomnia, though the lack of trained providers is a major barrier to accessibility. To address this issue, an online provider training platform, CBTI, was launched in April 2020.

Design and implementation of optics for the experiment for cryogenic large-aperture intensity mapping (EXCLAIM).

This work describes the design and implementation of optics for EXCLAIM, the EXperiment for Cryogenic Large-Aperture Intensity Mapping. EXCLAIM is a balloon-borne telescope that will measure integrated line emission from carbon monoxide at redshifts z < 1 and ionized carbon ([CII]) at redshifts z = 2.5 - 3.

A course-based undergraduate research experience (CURE) embedded within a summer undergraduate research experience demonstrates value-added benefits.

We hosted a nine-week NIH-funded summer undergraduate research experience in Environmental Health Sciences, the New College Environmental Health Science Scholars program, in which undergraduate students who were rising sophomores, juniors, and seniors receive both professional development and mentored research opportunities. In addition to this standard model of a summer research program, we added an additional professional development and skill-building activity, a course-based undergraduate research experience (CURE) performed by the whole group. Students designed and carried out an experiment in the CURE research project looking at the relationship between soil elemental content and sampling site location.

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.

Student perceptions of U.S. based school day physical activity best practices in relation to accelerometer-based sedentary behavior and activity.

Objective: To examine associations between student perceptions of school physical activity best practices and accelerometer-based physical activity during school days.

Methods: The sample was 758 students in grades 3rd-4th or 6th-7th (female-58 %; 31 % Black/African American) from 33 schools across five school districts in a Mid-Atlantic state in the U.S.

Cardiometabolic Multimorbidity and Dementia Onset among Middle-aged and Older Adults: Differences by Race/Ethnicity.

Background: Racial/ethnic minoritized groups in the U.S. have higher prevalence of cardiometabolic multimorbidity and experience higher risk of dementia.

The Performance of Ankle- and Waist-Based Accelerometry in Quantifying Physical Activity Intensity Among 6- to 24-Month-Year-Olds: A Semistructured Laboratory Study.

Objectives: We aim to quantify the performance of accelerometry in objectively measuring physical activity (PA) intensity among infants and toddlers.

Methods: Thirty-eight 6- to 24-month-olds participated in a 30-min, semistructured lab visit. Twenty-three (61%) children could walk independently.

Predictive equation derived from 6,497 doubly labelled water measurements enables the detection of erroneous self-reported energy intake.

Nutritional epidemiology aims to link dietary exposures to chronic disease, but the instruments for evaluating dietary intake are inaccurate. One way to identify unreliable data and the sources of errors is to compare estimated intakes with the total energy expenditure (TEE). In this study, we used the International Atomic Energy Agency Doubly Labeled Water Database to derive a predictive equation for TEE using 6,497 measures of TEE in individuals aged 4 to 96 years.

Morphology remodelling and membrane channel formation in synthetic cells via reconfigurable DNA nanorafts.

The shape of biological matter is central to cell function at different length scales and determines how cellular components recognize, interact and respond to one another. However, their shapes are often transient and hard to reprogramme. Here we construct a synthetic cell model composed of signal-responsive DNA nanorafts, biogenic pores and giant unilamellar vesicles (GUVs).

A hydrothermal coupling model for permafrost subgrade considering temperature gradient and its application.

The thermodynamic properties of frozen soil depend on its temperature state and ice content. Additionally, the permeability coefficient significantly affects both the temperature distribution and water movement. In this study, the dynamic variation of soil permeability coefficient with temperature is considered, the permeability coefficient is defined as a piecewise function with temperature as independent variable, and the hydrothermal coupling equation is established.

Differential reductions in alcohol consumption and cue-induced alcohol-seeking behavior following mGlu5 receptor inhibition in the prelimbic vs. infralimbic subregions of the rat prefrontal cortex.

Glutamatergic signaling is one of the primary targets of actions of alcohol in the brain, and dysregulated excitatory transmission in the prefrontal cortex (PFC) may contribute problematic drinking and relapse. A prominent component of glutamate signaling is the type 5 metabotropic glutamate (mGlu5) receptor. However, little is known about the role of this receptor type in subregions of the PFC that regulate either alcohol intake or alcohol-seeking behavior.

A new Drosophila melanogaster research resource: CRISPR-induced mutations for clonal analysis of fourth chromosome genes.

As part of an ongoing effort to generate comprehensive resources for the experimental analysis of fourth chromosome genes in Drosophila melanogaster, the Fourth Chromosome Resource Project has used CRISPR mutagenesis with single guide RNAs to isolate mutations in 62 of the 80 fourth chromosome, protein-coding genes. These mutations were induced on a fourth chromosome bearing a basal FRT insertion to facilitate experimental approaches involving FLP recombinase-induced mitotic recombination. To permit straightforward comparisons among mutant stocks, most of the mutations were generated on isogenic fourth chromosomes, which were then crossed into a common genetic background.

Detection of SARS-CoV-2 and a possible variant in shelter cats.

SARS-CoV-2 is the cause of mild to severe acute respiratory disease that led to significant loss of human lives worldwide between 2019 and 2022. The virus has been detected in various animals including cats and dogs making it a major public health concern and a One Health issue. In this study, conjunctival and pharyngeal swabs (n = 350) and serum samples (n = 350) were collected between July and December 2020 from cats that were housed in an animal shelter and tested for the infection of SARS-CoV-2 using real time reverse-transcription polymerase chain reaction (rRT-PCR) that targeted the N1 and N2 genes, and a SARS-CoV-2 surrogate virus neutralization Test (sVNT), respectively.

Sex-specific associations of serum testosterone with gray matter volume and cerebral blood flow in midlife individuals at risk for Alzheimer's disease.

Testosterone, an essential sex steroid hormone, influences brain health by impacting neurophysiology and neuropathology throughout the lifespan in both genders. However, human research in this area is limited, particularly in women. This study examines the associations between testosterone levels, gray matter volume (GMV) and cerebral blood flow (CBF) in midlife individuals at risk for Alzheimer's disease (AD), according to sex and menopausal status.

Rural Roads to cognitive Resilience (RRR): A prospective cohort study protocol.

Background: Ambient air pollution, detrimental built and social environments, social isolation (SI), low socioeconomic status (SES), and rural (versus urban) residence have been associated with cognitive decline and risk of Alzheimer's disease and related dementias (ADRD). Research is needed to investigate the influence of ambient air pollution and built and social environments on SI and cognitive decline among rural, disadvantaged, ethnic minority communities. To address this gap, this cohort study will recruit an ethnoracially diverse, rural Florida sample in geographic proximity to seasonal agricultural burning.

Single Extracellular VEsicle Nanoscopy-Universal Protocol (SEVEN-UP): Accessible Imaging Platform for Quantitative Characterization of Single Extracellular Vesicles.

Extracellular vesicles (EVs), membrane-encapsulated nanoparticles shed from all cells, are tightly involved in critical cellular functions. Moreover, EVs have recently emerged as exciting therapeutic modalities, delivery vectors, and biomarker sources. However, EVs are difficult to characterize, because they are typically small and heterogeneous in size, origin, and molecular content.

Six-Month Outcomes in the Long-Term Outcomes After the Multisystem Inflammatory Syndrome in Children Study.

Importance: Multisystem inflammatory syndrome in children (MIS-C) is a life-threatening complication of COVID-19 infection. Data on midterm outcomes are limited.

Objective: To characterize the frequency and time course of cardiac dysfunction (left ventricular ejection fraction [LVEF] <55%), coronary artery aneurysms (z score ≥2.

Discrimination and racial socialization profiles: Associations with Asian American adolescent attachment, activism, and self-esteem.

Theory and research suggest that racial discrimination is associated with attachment insecurity (Stern et al., 2022), whereas racial socialization is an integral aspect to fostering secure attachment with parents (Coard, 2022; Dunbar, Lozada, et al., 2022).

Dyadic working alliance, therapist insight skills, and client outcomes: Longitudinal mediation analyses.

A number of studies have shown an association between therapist skills (particularly insight skills) and the working alliance, but few studies have examined the directionality of this relationship. In addition, studies have used either the client or therapist report of the working alliance rather than a perspective. Thus, we examined whether (a) dyadic insight skills are indirectly related to client outcome through the working alliance and (b) the dyadic working alliance is indirectly related to client outcome through insight skills.
