Avenues towards reconciling wild and managed bee proponents.

Bees are crucial for food security and biodiversity. However, managed bees are increasingly considered drivers of wild bee declines, leading to stakeholder conflicts and restrictive policies. We propose avenues to reconcile wild and managed bee proponents and point out knowledge gaps that hinder the development of evidence-based policies.

Managing the parasitic honey bee mite Tropilaelaps mercedesae through combined cultural and chemical control methods.

The western honey bee (Apis mellifera) is severely impacted by the parasitic Tropilaelaps mercedesae mite, which has the capacity to outcompete Varroa destructor mites (the current leading cause of colony losses) and more rapidly overwhelm colonies. While T. mercedesae is native to Asia, it has recently expanded its geographic range and has the potential to devastate beekeeping worldwide if introduced to new regions.

Use of a Cyclic α-Alkylidene-β-Diketone as a Cleavable Linker Strategy for Antibody-Drug Conjugates.

In the fast-evolving landscape of targeted cancer therapies, the revolutionary class of biotherapeutics known as antibody-drug conjugates (ADCs) are taking center stage. Most clinically approved ADCs utilize cleavable linkers to temporarily attach potent cytotoxic payloads to antibodies, allowing selective payload release under tumor-specific conditions. In this study, we explored the utilization of 1-(4,4-dimethyl-2,6-dioxocyclohexylidene)ethyl (Dde), a cyclic β-diketone featuring an active alkylidene group, to develop a novel chemically labile linker.

Neonicotinoid exposure increases Varroa destructor (Mesostigmata: Varroidae) mite parasitism severity in honey bee colonies and is not mitigated by increased colony genetic diversity.

Agrochemical exposure is a major contributor to ecological declines worldwide, including the loss of crucial pollinator species. In addition to direct toxicity, field-relevant doses of pesticides can increase species' vulnerabilities to other stressors, including parasites. Experimental field demonstrations of potential interactive effects of pesticides and additional stressors are rare, as are tests of mechanisms via which pollinators tolerate pesticides.

Combined treatment with amitraz and thymol to manage Varroa destructor mites (Acari: Varroidae) in Apis mellifera honey bee colonies (Hymenoptera: Apidae).

The parasitic mite Varroa destructor (Anderson and Trueman) is one of the greatest stressors of Apis mellifera (L.) honey bee colonies. When Varroa infestations reach damaging levels during fall, rapid control is necessary to minimize damage to colonies.

The Use of Holographic Memory Resolution® to Improve the Physical and Biopsychosocial Symptoms of Chronic Pain: A Feasibility, Mixed Methods Study.

Objective: Holographic Memory Resolution® (HMR®), a mind-based therapy, has been used for decades as a nonpharmacologic intervention for trauma imprinting to alleviate depression, anxiety, pain, and post-traumatic stress disorder (PTSD). No clinical studies were found examining the use of HMR®. This study examined the feasibility and preliminary efficacy of administering HMR® to individuals experiencing chronic pain and related biopsychosocial symptoms.

Shift in virus composition in honeybees () following worldwide invasion by the parasitic mite and virus vector .

Invasive vectors can induce dramatic changes in disease epidemiology. While viral emergence following geographical range expansion of a vector is well known, the influence a vector can have at the level of the host's pathobiome is less well understood. Taking advantage of the formerly heterogeneous spatial distribution of the ectoparasitic mite that acts as potent virus vector among honeybees , we investigated the impact of its recent global spread on the viral community of honeybees in a retrospective study of historical samples.

No evidence to support the use of glycerol-oxalic acid mixtures delivered via paper towel for controlling Varroa destructor (Mesostigmata: Varroidae) mites in the Southeast United States.

A significant amount of researcher and practitioner effort has focused on developing new chemical controls for the parasitic Varroa destructor mite in beekeeping. One outcome of that has been the development and testing of "glycerol-oxalic acid" mixtures to place in colonies for extended periods of time, an off-label use of the otherwise legal miticide oxalic acid. The majority of circulated work on this approach was led by practitioners and published in nonacademic journals, highlighting a lack of effective partnership between practitioners and scientists and a possible failure of the extension mandate in beekeeping in the United States.

Development and evaluation of measures to assess self-determination in peripartum contraceptive decision-making.

Objectives: We aimed to adapt and validate person-centered measures to evaluate various contributors to self-determination in perinatal contraceptive decision-making.

Study Design: We developed and administered four scales adapted from existing measures in the context of Self-Determination Theory: the Treatment Self-Regulation Questionnaire (TSRQ), Perceived Competence Scale, modified Health Care Climate Questionnaire, and Important Other Climate Questionnaire. The TSRQ consists of three subscales: autonomous motivation, controlled motivation, and amotivation.

The Impact of Resilience and Perceived Autonomy Support on Medication Adherence Among Rural Older Adults With Hypertension.

Background: Adherence to antihypertension medications has been explored in previous studies; however, these studies generally focus on individuals who reside in urban areas. Improved understanding is needed regarding rural older adults who are self-managing medications for hypertension and the motivational factors that may influence adherence.

Objectives: The purpose of this study was to examine medication adherence among rural older adults with hypertension and the association with motivational factors as defined in self-determination theory, including quality of motivation (autonomous vs controlled), perceived competence, perceived autonomy support, and basic psychological needs satisfaction.

Motivation and accessing care among drug treatment court involved women: A sequential, mixed-methods approach.

Drug treatment courts (DTC) address substance use disorders (SUD) but not cooccurrencing HIV or hepatitis C virus (HCV). This pilot explored feasibility and preliminary outcomes of the Women's Initiative Supporting Health (WISH) intervention and health-related motivation, both based in self-determination theory (SDT) regarding HIV/HCV and SUD treatment. WISH feasibility study: 79 DTC women completed a one-time survey regarding motivation and willingness to engage in future interventions.

A blinded in vitro analysis of the intrinsic immunogenicity of hepatotoxic drugs: implications for preclinical risk assessment.

In vitro preclinical drug-induced liver injury (DILI) risk assessment relies largely on the use of hepatocytes to measure drug-specific changes in cell function or viability. Unfortunately, this does not provide indications toward the immunogenicity of drugs and/or the likelihood of idiosyncratic reactions in the clinic. This is because the molecular initiating event in immune DILI is an interaction of the drug-derived antigen with MHC proteins and the T-cell receptor.

Self-determination theory and the smoking cessation process: Daily electronic self-reports can identify the initiation of quit attempts.

Objectives: To examine the motivational predictors of the smoking cessation process at the between-persons and within-persons levels.

Methods: Mediation analyses were conducted on self-report data (N = 236) that were collected using interval contingent sampling over a 39-day study period.

Results: There was a high rate of attrition, as nearly 50% of participants were lost to follow-up.

The Global Forest Health Crisis: A Public-Good Social Dilemma in Need of International Collective Action.

Society is confronted by interconnected threats to ecological sustainability. Among these is the devastation of forests by destructive non-native pathogens and insects introduced through global trade, leading to the loss of critical ecosystem services and a global forest health crisis. We argue that the forest health crisis is a public-good social dilemma and propose a response framework that incorporates principles of collective action.

Design and rationale of behavioral nudges for diabetes prevention (BEGIN): A pragmatic, cluster randomized trial of text messaging and a decision aid intervention for primary care patients with prediabetes.

Background: Among 96 million U.S. adults with prediabetes, adoption of evidence-based treatment to prevent diabetes remains low.

Artificial pollination of kiwifruit (Actinidia chinensis Planch. var. chinensis) (Ericales: Actinidiaceae) results in greater fruit set compared to flowers pollinated by managed bees (Apis mellifera L. (Hymenoptera: Apidae) and Bombus impatiens Cresson (Hymenoptera: Apidae)).

Due to a lack of knowledge on the pollination requirements of kiwifruit cultivars grown within the United States, farmers simultaneously implement multiple pollination methods, like the rental of managed bee species or artificial pollination to achieve high fruit yields. However, implementing multiple pollination methods is costly and possibly an inefficient use of resources. We assessed the contribution of two managed bees (Apis mellifera and Bombus impatiens) to the pollination of kiwifruit by i) determining the relative abundance of kiwifruit pollen collected by foragers of each bee species, and ii) comparing fruit set and fruit quality among insect and artificially pollinated flowers through an insect exclusion experiment.

Identification of runs of homozygosity in Western honey bees () using whole-genome sequencing data.

Runs of homozygosity (ROH) are continuous homozygous segments that arise through the transmission of haplotypes that are identical by descent. The length and distribution of ROH segments provide insights into the genetic diversity of populations and can be associated with selection signatures. Here, we analyzed reconstructed whole-genome queen genotypes, from a pool-seq data experiment including 265 Western honeybee colonies from and .

Negative but antagonistic effects of neonicotinoid insecticides and ectoparasitic mites Varroa destructor on Apis mellifera honey bee food glands.

Collaborative brood care by workers is essential for the functionality of eusocial Apis mellifera honey bee colonies. The hypopharyngeal food glands of workers play a crucial role in this context. Even though there is consensus that ubiquitous ectoparasitic mites Varroa destructor and widespread insecticides, such as neonicotinoids, are major stressors for honey bee health, their impact alone and in combination on the feeding glands of workers is poorly understood.

The helping older people engage (HOPE) study: Protocol & COVID modifications for a randomized trial.

Objectives: Evidence-based strategies to reduce loneliness in later life are needed because loneliness impacts all domains of health, functioning, and quality of life. Volunteering is a promising strategy, as a large literature of observational studies documents associations between volunteering and better health and well-being. However, relatively few studies have used randomized controlled trials (RCTs) to examine benefits of volunteering, and none have examined loneliness.

Honey bee colony loss linked to parasites, pesticides and extreme weather across the United States.

Honey bee (Apis mellifera) colony loss is a widespread phenomenon with important economic and biological implications, whose drivers are still an open matter of investigation. We contribute to this line of research through a large-scale, multi-variable study combining multiple publicly accessible data sources. Specifically, we analyzed quarterly data covering the contiguous United States for the years 2015-2021, and combined open data on honey bee colony status and stressors, weather data, and land use.

Multiple mating by both sexes in an invasive insect species, Aethina tumida (Coleoptera: Nitidulidae).

Multiple mating by both sexes is common among sexually reproducing animals. Small hive beetles (SHB), Aethina tumida, are parasites of bee nests endemic to sub-Saharan Africa and have become a widespread invasive species. Despite the considerable economic damages they can cause, their basic biology remains poorly understood.
