ReBreed21-ET: Evaluation of a rapid resynchronization program that allows timed embryo transfer every 21 days.

This study evaluated the efficiency of a rapid resynchronization of ovulation program to allow timed embryo transfer (TET) every 21d in heifer embryo recipients. Holstein heifers (n = 510) had synchronized ovulation using a modified 5d CoSynch program for a TET (D7) after induced ovulation (D0). After TET, heifers were blocked by number of previous TETs and randomized into one of two resynchronization of ovulation programs: Resynch28 (n = 279), a traditional resynch program for TET 35d after previous TET; or ReBreed21-ET, a program designed to allow TET 21d after previous TET.

Housing hardship and health: Longitudinal evidence of the mediating role of health behaviors.

Housing instability is widely recognized as a major environmental factor that significantly shapes both health and overall well-being. This study added to the existing literature by examining the longitudinal relationship between housing-related hardship and self-rated health. Moreover, this study explored health behaviors-specifically substance use and lifestyle behaviors-as potential mediators that link housing hardship to health.

Prevalence of and risk factors for osteoporosis and fragility fracture in adults with cerebral palsy: A systematic review.

Aim: To systematically review the prevalence and incidence of osteoporosis, osteopenia, low bone mass, and fragility fracture in adults with cerebral palsy (CP), and identify the risk factors for osteoporosis and fracture.

Method: A systematic literature search was performed in the MEDLINE, PubMed, CINAHL, AMED, Cochrane Reviews, EMBASE, and EBM database reviews from inception until May 2024. Search terms covered a combination of keywords for CP, fracture, osteoporosis, incidence and prevalence, and risk factors.

Spatial-Structural Mechanisms of Racialized Disparities in Overdose Mortality: A Spatiotemporal Analysis.

Efforts to understand and respond to the opioid crisis have focused on overdose fatalities. Overdose mortality rates (ratios of overdoses resulting in death) are rarely examined though they are important indicators of harm reduction effectiveness. Factors that vary across urban communities likely determine which community members are receiving the resources needed to reduce fatal overdose risk.

Somatic CAG repeat expansion in blood associates with biomarkers of neurodegeneration in Huntington's disease decades before clinical motor diagnosis.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disease with the age at which characteristic symptoms manifest strongly influenced by inherited HTT CAG length. Somatic CAG expansion occurs throughout life and understanding the impact of somatic expansion on neurodegeneration is key to developing therapeutic targets. In 57 HD gene expanded (HDGE) individuals, ~23 years before their predicted clinical motor diagnosis, no significant decline in clinical, cognitive or neuropsychiatric function was observed over 4.

Association between herpes simplex virus infection and Alzheimer's disease biomarkers: analysis within the MAPT trial.

In vitro and animal studies have suggested that inoculation with herpes simplex virus 1 (HSV-1) can lead to amyloid deposits, hyperphosphorylation of tau, and/or neuronal loss. Here, we studied the association between HSV-1 and Alzheimer's disease biomarkers in humans. Our sample included 182 participants at risk of cognitive decline from the Multidomain Alzheimer Preventive Trial who had HSV-1 plasma serology and an amyloid PET scan.

A lot of noise about nothing? Speech-to-noise ratios rather than noise predict language outcomes in preschoolers.

It has been proposed that a childhood in a noisy household might lead to poor language skills and slow development of language areas of the brain. Notably, a direct link between noisy households and language development has not been confirmed. Households might have high levels of noise for a range of reasons, including situational (near a large road intersection or airport), family (large families), and cultural (differences in beliefs surrounding noise in the home, including media use).

Vitamin D-related genetic variants and prostate cancer risk in Black men.

Background: The relationship between vitamin D and prostate cancer has primarily been characterized among White men. Black men, however, have higher prostate cancer incidence and mortality rates, chronically low circulating vitamin D levels, and ancestry-specific genetic variants in vitamin D-related genes. Here, we examine critical genes in the vitamin D pathway and prostate cancer risk in Black men.

Estimating Earphone Level and Dose Using Real-Ear Measures and Ecological Momentary Assessment.

Purpose: Prior work estimating sound exposure dose from earphone use has typically measured earphone use time with retrospective questionnaires or device-based tracking, both of which have limitations. This research note presents an exploratory analysis of sound exposure dose from earphone use among college-aged adults using real-ear measures to estimate exposure level and ecological momentary assessment (EMA) to estimate use time.

Method: Earphone levels were measured at the ear drum of 53 college students using their own devices, earphones, and preferred music and speech stimuli at their normal listening volume.

Metabolic skinflint or spendthrift? Insights into ground sloth integument and thermophysiology revealed by biophysical modeling and clumped isotope paleothermometry.

Unlabelled: Remains of megatheres have been known since the 18th -century and were among the first megafaunal vertebrates to be studied. While several examples of preserved integument show a thick coverage of fur for smaller ground sloths living in cold climates such as and , comparatively very little is known about megathere skin. Assuming a typical placental mammal metabolism, it was previously hypothesized that megatheres would have had little-to-no fur as they achieved giant body sizes.

Plasma biomarkers of amyloid, tau, astrogliosis, and axonal injury in a mixed memory clinic cohort.

Introduction: Studies have shown that blood biomarkers can differentiate dementia disorders. However, the diagnosis of dementia still relies primarily on cerebrospinal fluid and imaging modalities. The new disease-modifying treatments call for more widely applicable biomarkers.

sTREM2 in discordant CSF Aβ and p-tau181.

Introduction: Little is known about the factors underpinning discordant cerebrospinal fluid (CSF) amyloid beta (Aβ) versus p-tau181/Aβ or CSF Aβ versus Aβ positron emission tomography (PET).

Methods: We stratified 570 non-demented Alzheimer's Disease Neuroimaging Initiative (ADNI) participants by Aβ PET and further by CSF Aβ or p-tau181/Aβ. We used analysis of covariance testing adjusting for covariates, followed by Tukey post hoc pairwise comparisons, to compare CSF soluble triggering receptor expressed on myeloid cells-2 (sTREM2) across four participant groups: CSF+ with CSF- , CSF- with CSF+ , and concordant CSF/CSF.

Unveiling complexities: Examining the role of traumatic loss in shaping the interplay between black maternal mental health and maternal bonding.

Black women are more likely to experience traumatic birthing events, more likely to experience perinatal depression, and less likely to receive mental health treatment than women of other racial and ethnic backgrounds, and yet largely overlooked in perinatal mental health research. This pilot study seeks to understand how unacceptable racial disparities and adverse perinatal outcomes influence Black maternal depression and maternal bonding by exploring how prior traumatic loss moderates the relationship between depression and bonding during a subsequent pregnancy among a sample of Black mothers. We use survey data collected from 75 Black mothers as part of the Black Fathers, Equal Partners in Promoting Maternal and Infant Health study, a collaboration between the University of Wisconsin Madison and the African American Breastfeeding Network in Milwaukee, Wisconsin, USA.

Enhanced efficiency fertilizers, potato production, and nitrate leaching in the Wisconsin Central Sands.

Maintaining yield goals while reducing nitrate-nitrogen (NO-N) leaching to groundwater is a challenge for potato (Solanum tuberosum) production in the Wisconsin Central Sands as well as across the United States. The objectives of this study were to quantify the effect of conventional and enhanced efficiency nitrogen (N) fertilizers on NO-N leaching, crop yield, and N uptake in potatoes. We compared five N treatments, which include a 0 N control and 280 kg ha as ammonium sulfate and ammonium nitrate (AS/AN), polymer-coated urea (PCU), urea with a urease inhibitor (Urea+UI), or urea with a UI and a nitrification inhibitor (Urea+UI+NI).

Frequent, heterogenous fire supports a forest owl assemblage.

Fire shapes biodiversity in many forested ecosystems, but historical management practices and anthropogenic climate change have led to larger, more severe fires that threaten many animal species where such disturbances do not occur naturally. As predators, owls can play important ecological roles in biological communities, but how changing fire regimes affect individual species and species assemblages is largely unknown. Here, we examined the impact of fire severity, history, and configuration over the past 35 years on an assemblage of six forest owl species in the Sierra Nevada, California, using ecosystem-scale passive acoustic monitoring.

Ancient reticulation, incomplete lineage sorting and the evolution of the pyrenoid at the dawn of hornwort diversification.

Background And Aims: Resolving the phylogeny of hornworts is critical in understanding the evolution of key morphological characters that are unique to the group, including the pyrenoid. Extensive phylogenomic analyses have revealed unexpected complexities in the placement of Leiosporoceros, the previously identified sister taxon to other hornworts. We explore the role of incomplete lineage sorting (ILS) and ancient reticulation in resolving interrelationships and comprehending the diversification and evolutionary processes within hornworts.

Terahertz conductivity of two-dimensional materials: a review.

Two-dimensional (2D) van der Waals materials are shaping the landscape of next-generation devices, offering significant technological value thanks to their unique, tunable, and layer-dependent electronic and optoelectronic properties. Time-domain spectroscopic techniques at terahertz (THz) frequencies offer noninvasive, contact-free methods for characterizing the dynamics of carriers in 2D materials. They also pave the path toward the applications of 2D materials in detection, imaging, manufacturing, and communication within the increasingly important THz frequency range.

Large Language Models and Large Multimodal Models in Medical Imaging: A Primer for Physicians.

Large language models (LLMs) are poised to have a disruptive impact on health care. Numerous studies have demonstrated promising applications of LLMs in medical imaging, and this number will grow as LLMs further evolve into large multimodal models (LMMs) capable of processing both text and images. Given the substantial roles that LLMs and LMMs will have in health care, it is important for physicians to understand the underlying principles of these technologies so they can use them more effectively and responsibly and help guide their development.

Relationship between left ventricular shape and cardiovascular risk factors: comparison between the Multi-Ethnic Study of Atherosclerosis and UK Biobank.

Background: Statistical shape atlases have been used in large-cohort studies to investigate relationships between heart shape and risk factors. The generalisability of these relationships between cohorts is unknown. The aims of this study were to compare left ventricular (LV) shapes in patients with differing cardiovascular risk factor profiles from two cohorts and to investigate whether LV shape scores generated with respect to a reference cohort can be directly used to study shape differences in another cohort.

Sexual Violence and Shame: A Meta-Analysis.

Although sexual violence (SV) has been hypothesized to increase shame, the relationship between SV and shame has not been quantified. Addressing this gap is essential for developing targeted interventions for survivors, as shame is a transdiagnostic risk factor for numerous forms of psychopathology and a barrier to service-seeking. This meta-analysis first examines whether individuals exposed to SV demonstrate higher shame than individuals who reported no SV exposure.

p-Type BiVO for Solar O Reduction to HO.

Photoelectrochemical cells (PECs) can directly utilize solar energy to drive chemical reactions to produce fuels and chemicals. Oxide-based photoelectrodes in general exhibit enhanced stability against photocorrosion, which is a critical advantage for building a sustainable PEC. However, most oxide-based semiconductors are n-type, and p-type oxides that can be used as photocathodes are limited.

The mechanisms of frequency tuning in gecko auditory hair cells.

We developed an isolated auditory papilla of the crested gecko to record from the hair cells and explore the origins of frequency tuning. Low-frequency cells displayed electrical tuning, dependent on Ca-activated K channels; high-frequency cells, overlain with sallets, showed a variation in hair bundle stiffness which when combined with sallet mass could provide a mechanical resonance of 1 to 6 kHz. Sinusoidal electrical currents injected extracellularly evoked hair bundle oscillations at twice the stimulation frequency, consistent with fast electromechanical responses from hair bundles of two opposing orientations, as occur in the sallets.

Leveraging Ergonomics and Human Factors (E/HF) for community impact: what have we learned about how to make a difference.

Ergonomics and Human Factors (E/HF) practitioners are increasingly engaged in projects meant to centre underserved communities and reduce inequities. The subdiscipline of E/HF that has emerged to explore the application of E/HF in this way is called community ergonomics. In this qualitative-descriptive study, we reflect on the progress made in the field of community ergonomics since its original conceptualisation in 1994.
