Large Differences in Herbivore Performance Emerge From Simple Herbivore Behaviours and Fine-Scale Spatial Heterogeneity in Phytochemistry.

Patterns of phytochemistry localisation in plant tissues are diverse within and across leaves. These spatial heterogeneities are important to the fitness of herbivores, but their effects on herbivore foraging and dietary experience remain elusive. We manipulated the spatial variance and clusteredness of a plant toxin in a synthetic diet landscape on which individual caterpillars fed.

Allostatic Load, Educational Attainment, and Risk of Cancer Mortality Among US Men.

Importance: Health disparities among racial and ethnic minoritized populations, particularly for cancer mortality rates, remain a major public health concern. Men from underrepresented backgrounds (Black and Hispanic men, specifically) face the pervasive effects of discrimination in their daily lives, which also contribute to the complex associations among allostatic load (a marker of chronic stress), educational opportunities, and elevated risks of cancer mortality.

Objective: To elucidate the associations among educational attainment, allostatic load, and cancer mortality risk among men.

Resilient plants, sustainable future.

The accelerated pace of climate change over the past several years should serve as a wake-up call for all scientists, farmers, and decision makers, as it severely threatens our food supply and could result in famine, migration, war, and an overall destabilization of our society. Rapid and significant changes are therefore needed in the way we conduct research on plant resilience, develop new crop varieties, and cultivate those crops in our agricultural systems. Here, we describe the main bottlenecks for these processes and outline a set of key recommendations on how to accelerate research in this critical area for our society.

Disparities in Genetic Testing for Inborn Errors of Immunity.

Background: Inequities in genetic testing have been documented in a range of diseases, and no-charge genetic testing programs have been proposed as a means to enhance access. However, no studies have examined disparities in genetic testing for inborn errors of immunity (IEI) and the impact of no-charge programs on testing equity.

Objective: To examine socioeconomic, geographic, and racial disparities in the uptake of genetic testing for IEI in the United States and the impact of a no-charge sponsored program on testing equity.

PARP enzyme de novo synthesis of protein-free poly(ADP-ribose).

PARP enzymes transfer ADP-ribose from NAD onto proteins as a covalent modification that regulates multiple aspects of cell biology. Here, we identify an undiscovered catalytic activity for human PARP1: de novo generation of free PAR molecules that are not attached to proteins. Free PAR production arises when a molecule of NAD or ADP-ribose docks in the PARP1 acceptor site and attaches to an NAD molecule bound to the donor site, releasing nicotinamide and initiating ADP-ribose chains that emanate from NAD/ADP-ribose rather than protein.

Unique cortical and subcortical activation patterns for different conspecific calls in marmosets.

The common marmoset () is known for its highly vocal nature, displaying a diverse range of calls. Functional imaging in marmosets has shown that the processing of conspecific calls activates a brain network that includes fronto-temporal areas. It is currently unknown whether different call types activate the same or different networks.

Pramipexole, a D3 receptor agonist, increases cortical gamma power and biochemical correlates of cortical excitation; implications for mood disorders.

Major depressive disorder (MDD) has been associated with deficits in working memory as well as underlying gamma oscillation power. Consistent with this, overall reductions in cortical excitation have also been described with MDD. In previous work, we have demonstrated that the monoamine reuptake inhibitor venlafaxine increases gamma oscillation power in ex vivo hippocampal slices and that this is associated with concomitant increases in pyramidal arbour and reduced levels of plasticity-restricting perineuronal nets (PNNs).

RF shimming in the cervical spinal cord at 7 T.

Purpose: Advancing the development of 7 T MRI for spinal cord imaging is crucial for the enhanced diagnosis and monitoring of various neurodegenerative diseases and traumas. However, a significant challenge at this field strength is the transmit field inhomogeneity. Such inhomogeneity is particularly problematic for imaging the small, deep anatomical structures of the cervical spinal cord, as it can cause uneven signal intensity and elevate the local specific absorption ratio, compromising image quality.

Background: Stroke is a worldwide concern due to its high disability and mortality rates, especially in many countries entering ageing societies. This study aims to understand the spatial heterogeneity of stroke onset and residential environment influence scopes from multiscale.

Methods: The 2013 to 2022 spatiotemporal distribution pattern of stroke onset was obtained via out-patient data from a hospital in Shanghai.

Development of an inhibitor of the mutagenic SOS response that suppresses the evolution of quinolone antibiotic resistance.

Antimicrobial resistance (AMR) is a growing threat to health globally, with the potential to render numerous medical procedures so dangerous as to be impractical. There is therefore an urgent need for new molecules that function through novel mechanisms of action to combat AMR. The bacterial DNA-repair and SOS-response pathways promote survival of pathogens in infection settings and also activate hypermutation and resistance mechanisms, making these pathways attractive targets for new therapeutics.

Using Runs of Homozygosity and Machine Learning to Disentangle Sources of Inbreeding and Infer Self-Fertilization Rates.

Runs of homozygosity (ROHs) are indicative of elevated homozygosity and inbreeding due to mating of closely related individuals. Self-fertilization can be a major source of inbreeding which elevates genome-wide homozygosity and thus should also create long ROHs. While ROHs are frequently used to understand inbreeding in the context of conservation and selective breeding, as well as for consanguinity of populations and their demographic history, it remains unclear how ROH characteristics are altered by selfing and if this confounds expected signatures of inbreeding due to demographic change.

A Novel Surgical Landmark to Identify the Recurrent Laryngeal Nerve.

Background: Although several surgical landmarks have been proposed to localize the recurrent laryngeal nerve (RLN), there is still no reliable landmark.

Aims: To validate the reliability of a novel reference point at the intersection of the inferior border of the cricopharyngeal muscle and the inferior cornu of thyroid cartilage for locating the RLN.

Study Design: Cadaver dissection study in the academic department of otolaryngology-head and neck surgery.

Evaluation of deep-learning TSE images in clinical musculoskeletal imaging.

In this study, we compared the fat-saturated (FS) and non-FS turbo spin echo (TSE) magnetic resonance imaging knee sequences reconstructed conventionally (conventional-TSE) against a deep learning-based reconstruction of accelerated TSE (DL-TSE) scans. A total of 232 conventional-TSE and DL-TSE image pairs were acquired for comparison. For each consenting patient, one of the clinically acquired conventional-TSE proton density-weighted sequences in the sagittal or coronal planes (FS and non-FS), or in the axial plane (non-FS), was repeated using a research DL-TSE sequence.

Racial and Ethnic Composition of Departments of Health Policy & Management and Health Education & Behavioral Sciences.

The diversity of racial/ethnic representation in the health services and policy research (HSPR) workforce plays a crucial role in addressing the health needs of underserved populations. We assessed changes (between 2012 and 2022) in the racial/ethnic composition of students and faculty from departments of Health Policy & Management (HPM) and Health Education & Behavioral Sciences (HEBS) among the Association of Schools and Programs of Public Health member institutions. We analyzed annual data from over 40 institutions that reported student and faculty data in 2012 and 2022 within each department.

Harnessing the power within: engineering the microbiome for enhanced gynecologic health.

Abstract: Although numerous studies have demonstrated the impact of microbiome manipulation on human health, research on the microbiome's influence on female health remains relatively limited despite substantial disease burden. In light of this, we present a selected review of clinical trials and preclinical studies targeting both the vaginal and gut microbiomes for the prevention or treatment of various gynecologic conditions. Specifically, we explore studies that leverage microbiota transplants, probiotics, prebiotics, diet modifications, and engineered microbial strains.

Methods: The carotid coil included 8 total RF elements, with left and right subarrays, each consisting of 4 overlapping loops with RF shields. Electromagnetic (EM) simulations were performed to optimize and improve the transmit performance of the array by determining the optimal distance between the RF shield and each subarray.

Telehealth-Delivered Radically Open Dialectical Behavior Therapy for Adolescents (RO DBT-A): A Pilot Mixed-Methods Study.

Objective: Disorders related to overcontrol frequently first appear during adolescence, are highly comorbid, and show limited treatment response, necessitating the adaptation of radically open dialectical behavior therapy (RO DBT; a transdiagnostic treatment targeting overcontrol) for adolescents (RO DBT-A). This study tested the preliminary efficacy of telehealth-delivered RO DBT-A in a heterogeneous clinical sample of youths.

Methods: The sample consisted of 20 female participants ages 13-21 with elevated overcontrol; most were White (75%) and non-Hispanic/Latino (80%).

: Evaluating a Forum Theater Production to Activate Youth Violence Prevention Strategies in Schools.

Background: Youth violence that takes place within school settings exposes youth to serious social, mental and physical consequences that affect education performance, and life opportunities. Previous work shows positive youth development frameworks can promote social-emotional learning by enhancing empathy and building problem-solving and conflict management skills. Theater-based interventions have been shown to enhance social emotional development by privileging youth voices, and building youth capacities and strengths.

Early Emotion Development Intervention Improves Mental Health Outcomes in Low-Income, High-Risk Community Children.

Children living in poverty and facing related forms of adversity are at higher risk for experiencing concurrent and later psychopathology. Although negative psychological outcomes can be improved by enhancing sensitive and responsive caregiving early in development, interventions targeting the caregiver-child dyad are not readily accessible. The present study investigated the feasibility and effectiveness of delivering a shortened eight-session form of Parent-Child Interaction Therapy-Emotion Development (PCIT-ED) in-person or remotely as an early intervention for 3-6-year-old children (N = 62) at elevated risk for psychopathology who were growing up in low-income communities.
