Bumble bee gut microbial community structure differs between species and commercial suppliers, but metabolic potential remains largely consistent.

Bumble bees are key pollinators for natural and agricultural plant communities. Their health and performance are supported by a core gut microbiota composed of a few bacterial taxa. However, the taxonomic composition and community structure of bumble bee gut microbiotas can vary with bee species, environment, and origin (i.

Background: For people with Parkinson's disease (PwPD), high-intensity exercise in individual or group format can improve function and quality of life (QoL). Individualized virtual exercise programs have been effective for people with PD, but the feasibility and impact of group exercise in the virtual format has not been investigated.

Purpose: To compare the effect of individual and group virtual exercise on functional mobility and QoL for PwPD.

Mapping Multilevel Contributions to the Sexual Victimization of Trans Women and Trans Feminine People: A Qualitative Intersectional Stigma Analysis.

We aimed to characterize and conceptually organize multilevel factors associated with the sexual victimization experiences of trans women and trans feminine people to advance violence prevention interventions for health-equity. Between October 2020 and July 2021, we conducted in-depth interviews with 17 expert informants in New York City, which we transcribed, coded, and analyzed. Qualitative insights were derived through an intensive, team-based iterative coding strategy resulting in the development of an exhaustive set of consensus codes which were organized and interpreted in a multi-level structure.

How to implement compassionate leadership in nursing teams.

This article explains how to implement compassionate leadership in nursing teams. Compassionate leadership is an approach that aims to empower and support staff through four main behavioural principles - attending, understanding, empathising and helping. • Compassionate leadership can be practised by all nurses, irrespective of their role or position, and with individuals or groups.

Changes in bumblebee queen gut microbiotas during and after overwintering diapause.

Bumblebees are key pollinators with gut microbiotas that support host health. After bumblebee queens undergo winter diapause, which occurs before spring colony establishment, their gut microbiotas are disturbed, but little is known about community dynamics during diapause itself. Queen gut microbiotas also help seed worker microbiotas, so it is important that they recover post-diapause to a typical community structure, a process that may be impeded by pesticide exposure.

Scab Intensity in Pecan Trees in Relation to Hedge-Pruning Methods.

Pecan is a valuable nut crop cultivated in the southeastern United States. Among the major yield-limiting factors in the region is scab, caused by the plant pathogenic fungus . Managing scab in tall trees (15 to 25+ m) in pecan orchards is challenging because of the limitations of getting sufficient spray coverage throughout the canopy.

Exposure to a fungicide for a field-realistic duration does not alter bumble bee fecal microbiota structure.

Social bees are frequently exposed to pesticides when foraging on nectar and pollen. Recent research has shown that pesticide exposure not only impacts social bee host health but can also alter the community structure of social bee gut microbiotas. However, most research on pesticide-bee gut microbiota interactions has been conducted in honey bees; bumble bees, native North American pollinators, have received less attention and, due to differences in their ecology, may be exposed to certain pesticides for shorter durations than honey bees.

Seasonal dynamics in the mammalian microbiome between disparate environments.

Host-associated bacterial microbiomes can facilitate host acclimation to seasonal environmental change and are hypothesized to help hosts cope with recent anthropogenic environmental perturbations (e.g., landscape modification).

An optimized radioimmunoassay for quantification of total serum thyroxine (T4) in fetal, neonatal, and pregnant rats.

Identifying xenobiotics that interrupt the thyroid axis has significant public health implications, given that thyroid hormones are required for brain development. As such, some developmental and reproductive toxicology (DART) studies now require or recommend serum total thyroxine (T4) measurements in pregnant, lactating, and developing rats. However, serum T4 concentrations are normally low in the fetus and pup which makes quantification difficult.

Process adaptations to community-engaged research for preventing victimization against trans women: Failure as a blueprint toward nonexploitative implementation science.

Effective violence prevention interventions are largely inaccessible to trans women and trans femmes, despite clear evidence that disproportionate exposure to experiences of victimization is a social determinant of health disparity. Community-engaged implementation science paradigms hold promise for guiding research psychologists in the delivery of evidence-based programming to address drivers of health disparities impacting trans women and trans femmes. Unfortunately, guidance on how to engage in a process of real-time self-reflection to note where implementation is failing in its goals to establish reciprocal and sustainable (i.

Implementation of empowerment self-defense programming in a university counseling center: An effective sexual violence prevention delivery model.

Empowerment Self-Defense (ESD) is a sexual violence prevention approach backed by rigorous empirical research, yet its availability on college campuses is limited. This manuscript evaluates the feasibility and efficacy of an ESD program embedded within a university counseling center. Participants completed an 8-session ESD intervention and group counseling program.

Cancer-Peer Connection in the Context of Adolescent and Young Adult Cancer: A Qualitative Exploration.

This qualitative study examined experiences and attitudes related to cancer-peer interactions among adolescent and young adult (AYA) cancer survivors. Twenty-six survivors, aged 16-24 years who were diagnosed with cancer between the ages of 14 and 18, completed one-on-one semistructured interviews as part of a larger study. Interviews were coded and analyzed using an iterative consensus and data-driven approach.

A qualitative analysis of the context and characteristics of trauma exposure among sexual minority survivors: Implications for posttraumatic stress disorder assessment and clinical practice.

Objective: Sexual minority individuals are exposed to traumatic harms unique to the shared cultural experience of living under conditions of identity-based stigma, discrimination, and marginalization. However, the context and characteristics by which this culture shapes traumatic experiences among sexual minority people are poorly specified in the research literature, leaving even well-intentioned mental health professionals inadequately prepared to treat sexual minority trauma survivors in a culturally affirming, tailored, and evidence-based manner.

Method: To begin to address this gap, we conducted a thematic analysis of descriptions of 52 (5th ed.

Pesticide-induced disturbances of bee gut microbiotas.

Social bee gut microbiotas play key roles in host health and performance. Worryingly, a growing body of literature shows that pesticide exposure can disturb these microbiotas. Most studies examine changes in taxonomic composition in Western honey bee (Apis mellifera) gut microbiotas caused by insecticide exposure.

Thyroid Disruptors: Extrathyroidal Sites of Chemical Action and Neurodevelopmental Outcome-An Examination Using Triclosan and Perfluorohexane Sulfonate.

Many xenobiotics are identified as potential thyroid disruptors due to their action to reduce circulating levels of thyroid hormone, most notably thyroxine (T4). Developmental neurotoxicity is a primary concern for thyroid disrupting chemicals yet correlating the impact of chemically induced changes in serum T4 to perturbed brain development remains elusive. A number of thyroid-specific neurodevelopmental assays have been proposed, based largely on the model thyroid hormone synthesis inhibitor propylthiouracil (PTU).

Effect of Tractor Speed and Spray Application Volume on Severity of Scab and Fruit Weight at Different Heights in the Canopy of Tall Pecan Trees.

Scab (caused by ) is the most important yield-limiting disease of pecan in the southeastern USA. On susceptible cultivars, the disease is managed using fungicides, but spray coverage is an issue in tall trees. In four experiments, we used an air-blast sprayer to compare scab severity on fruit at 5.

The Effect of Tractor Speed and Canopy Position on Fungicide Spray Deposition and Peach Scab Incidence and Severity.

Peach scab, caused by , is a damaging disease of peach in the southeastern United States. Thus, fungicides are applied to reduce peach scab. Tractor speed was investigated as a variable affecting spray deposition and disease control in relation to volume applied.

A Comparison of Ground-Based Air-Blast Sprayer and Aircraft Application of Fungicides to Manage Scab in Tall Pecan Trees.

Pecan scab (caused by ) is a destructive disease of pecan in the southeastern United States. Susceptible cultivars must be sprayed with fungicide every 10 to 21 days to ensure yield and kernel quality. Fungicide is most often applied using large orchard air-blast sprayers.

Towards a catalogue of biodiversity databases: An ontological case study.

Biodiversity informatics depends on digital access to credible information about species. Many online resources host species' data, but the lack of categorisation for these resources inhibits the growth of this entire field. To explore possible solutions, we examined the (now retired) Biodiversity Information Projects of the World (BIPW) dataset created by the Biodiversity Information Standards (TDWG); this project, which ran from 2007-2015 (officially removed from the TDWG website in 2018) was an attempt at organising the Web's biodiversity databases into an indexed list.
