Hover flies are dual ecosystem service providers that have been relatively understudied in orchard ecosystems.

Preferential potentiation of AMPA-mediated currents in brainstem hypoglossal motoneurons by subchronic exposure of mice expressing the human superoxide dismutase 1 G93A gene mutation to neurotoxicant methylmercury in vivo.

The exact causes of Amyotrophic lateral sclerosis (ALS), a progressive and fatal neurological disorder due to loss of upper and/or lower motoneurons, remain elusive. Gene-environment interactions are believed to be an important factor in the development of ALS. We previously showed that in vivo exposure of mice overexpressing the human superoxide dismutase 1 (hSOD1) gene mutation (hSOD1G93A; G93A), a mouse model for ALS, to environmental neurotoxicant methylmercury (MeHg) accelerated the onset of ALS-like phenotype.

Immune response to COVID-19 vaccination in a population with a history of elevated exposure to per- and polyfluoroalkyl substances (PFAS) through drinking water.

Background: Exposure to per- and polyfluoroalkyl substances (PFAS) has been linked to lower vaccine-induced antibody concentrations in children, while data from adults remains limited and equivocal. Characteristics of PFAS exposure and age at vaccination may modify such effects.

Objective: We used the mass administration of novel COVID-19 vaccines to test the hypothesis that prior exposure to environmentally-relevant concentrations of PFAS affect antibody response to vaccines in adolescents and adults.

Toward a Data-based Approach to the Selection of Applied Behavior Analysis Program Characteristics.

There is a paucity of data that describe how program characteristics relate to program outcome goals. This gap limits the use of data to guide and support decisions concerning the selection of applied behavior analysis (ABA) program characteristics. Therefore, the purpose of the present study was to describe a methodology for the evaluation of the relationships between program characteristics and program outcome goals in the context of identifying the ideal program characteristics to propose for a new master of science in ABA program at Franciscan Missionaries of Our Lady University (FranU).

Predicting Substance Use Treatment Failure with Transfer Learning.

Transfer learning, which involves repurposing a trained model on a related task, may allow for better predictions with substance use data than models that are trained using the target data alone. This approach may also be useful for small clinical datasets. The current study examined a method of classifying substance use treatment success using transfer learning.

Tutorial: Artificial neural networks to analyze single-case experimental designs.

Since the start of the 21st century, few advances have had as far-reaching impact in science as the widespread adoption of artificial neural networks in fields as diverse as fundamental physics, clinical medicine, and psychology. In research methods, one promising area for the adoption of artificial neural networks involves the analysis of single-case experimental designs. Given that these types of networks are not generally part of training in the psychological sciences, the purpose of our article is to provide a step-by-step introduction to using artificial neural networks to analyze single-case designs.

Prevalence, incidence, and years-lived with disability due to oral disorders in Brazil: an analysis of the Global Burden of Disease Study 2019.

Introduction: Epidemiological surveys revealed that Brazil has a high burden of oral diseases. However, no prior study has reported estimates of untreated dental caries, periodontitis, and edentulism over a three-decade period. The objective of this study is to report the trends of prevalence, incidence, and years-lived with disability (YLDs) due to untreated dental caries in primary and permanent teeth, periodontitis, and edentulism in Brazil between 1990 and 2019.

Machine Learning for Supplementing Behavioral Assessment.

The Questions About Behavioral Function (QABF) has a high degree of convergent validity, but there is still a lack of agreement between the results of the assessment and the results of experimental function analysis. Machine learning (ML) may improve the validity of assessments by using data to build a mathematical model for more accurate predictions. We used published QABF and subsequent functional analyses to train ML models to identify the function of behavior.

Facilitating engagement of persons with opioid use disorder in treatment for hepatitis C virus infection via telemedicine: Stories of onsite case managers.

Although hepatitis C virus (HCV) infection has high prevalence and incidence in persons with opioid use disorder (PWOUD), their engagement in HCV care has been limited due to a variety of factors. In an ongoing multisite study at 12 opioid treatment programs (OTPs) throughout New York State (NYS), we have been evaluating telemedicine accompanied by onsite administration of direct acting antiviral (DAA) medications compared with usual care including offsite referral to a liver specialist for HCV management. Each site has a case manager (CM) who is responsible for all study-related activities including participant recruitment, facilitating telemedicine interactions, retention in care, and data collection.

Australia: A Continent Without Native Powdery Mildews? The First Comprehensive Catalog Indicates Recent Introductions and Multiple Host Range Expansion Events, and Leads to the Re-discovery of as a New Lineage of the Erysiphales.

In contrast to Eurasia and North America, powdery mildews (Ascomycota, Erysiphales) are understudied in Australia. There are over 900 species known globally, with fewer than currently 60 recorded from Australia. Some of the Australian records are doubtful as the identifications were presumptive, being based on host plant-pathogen lists from overseas.

Racial and Ethnic Disparities in Genetic Testing at a Hereditary Breast and Ovarian Cancer Center.

Background: Prior studies suggest that referral to genetic counseling and completion of genetic testing vary by race/ethnicity; however, the data are limited.

Objective: We sought to evaluate patterns of genetic testing and clinical outcomes across race/ethnicity at a hereditary breast and ovarian cancer center.

Design: The medical records for all patients undergoing genetic assessment at a hereditary breast and ovarian cancer center were reviewed and stratified by self-reported race/ethnicity (non-Hispanic White, Hispanic, non-Hispanic Black, and Asian).

Prospective Feasibility Trial of a Novel Strategy of Facilitated Cascade Genetic Testing Using Telephone Counseling.

Patients And Methods: Probands with newly diagnosed cancer-associated pathogenic variants were offered facilitated cascade testing whereby the genetics team identified and contacted ARRs by telephone to disclose the familial pathogenic variant and offer telephone counseling and mailed saliva testing. Results and guideline-based recommendations were reviewed by telephone and shared with the primary care physician.

Results: Thirty probands were enrolled, and 114 ARRs were identified.

The Use of Stimulus Preference Assessments for Persons with Neurocognitive Disorder: A Literature Review.

: Stimulus preference assessments are a systematic, observation-based approach for identifying preferences among individuals with impaired communication skills. The purpose of this paper is to provide a review of the existing empirical literature that has utilized these methods with persons who have neurocognitive disorder (NCD).: Studies were identified by searching online databases using a variety of search terms.

An enriched network motif family regulates multistep cell fate transitions with restricted reversibility.

Multistep cell fate transitions with stepwise changes of transcriptional profiles are common to many developmental, regenerative and pathological processes. The multiple intermediate cell lineage states can serve as differentiation checkpoints or branching points for channeling cells to more than one lineages. However, mechanisms underlying these transitions remain elusive.

Evaluating a Gene-Environment Interaction in Amyotrophic Lateral Sclerosis: Methylmercury Exposure and Mutated SOD1.

Purpose Of Review: Gene-environment (GxE) interactions likely contribute to numerous diseases, but are often difficult to model in the laboratory. Such interactions have been widely hypothesized for amyotrophic lateral sclerosis (ALS); recent controlled laboratory studies are discussed here and hypotheses related to possible mechanisms of action are offered. Using methylmercury exposure and mutated SOD1 to model the impacts of such an interaction, we interpret evidence about their respective mechanisms of toxicity to interrogate the possibility of additive (or synergistic) effects when combined.

Exposure to a PBDE/OH-BDE mixture alters juvenile zebrafish (Danio rerio) development.

Polybrominated diphenyl ethers (PBDEs) and their metabolites (e.g., hydroxylated BDEs [OH-BDEs]) are contaminants frequently detected together in human tissues and are structurally similar to thyroid hormones.

Persistent behavioral effects following early life exposure to retinoic acid or valproic acid in zebrafish.

Background: Moderate to severe dysregulation in retinoid signaling during early development is associated with a constellation of physical malformations and/or neural tube defects, including spina bifida. It is thought that more subtle dysregulation of this system, which might be achievable via dietary (i.e.

Teratogenic, bioenergetic, and behavioral effects of exposure to total particulate matter on early development of zebrafish (Danio rerio) are not mimicked by nicotine.

Cigarette smoke has been associated with a number of pathologies; however, the mechanisms leading to developmental effects are yet to be fully understood. The zebrafish embryo is regarded as a 'bridge model'; however, not many studies examined its applicability to cigarette smoke toxicity. This study examined the effects of total particulate matter (TPM) from 3R4F reference cigarettes on the early development of zebrafish (Danio rerio).

Persisting effects of a PBDE metabolite, 6-OH-BDE-47, on larval and juvenile zebrafish swimming behavior.

Polybrominated diphenyl ethers (PBDEs) are persistent organic pollutants that are widely detected in the environment, biota, and humans. In mammals, PBDEs can be oxidatively metabolized to form hydroxylated polybrominated diphenyl ethers (OH-BDEs). While studies have examined behavioral deficits or alterations induced by exposure to PBDEs in both rodents and fish, no study to date has explored behavioral effects from exposure to OH-BDEs, which have been shown to have greater endocrine disrupting potential compared to PBDEs.

Neurobehavioral impairments caused by developmental imidacloprid exposure in zebrafish.

Background: Neonicotinoid insecticides are becoming more widely applied as organophosphate (OP) insecticides are decreasing in use. Because of their relative specificity to insect nicotinic receptors, they are thought to have reduced risk of neurotoxicity in vertebrates. However, there is scant published literature concerning the neurobehavioral effects of developmental exposure of vertebrates to neonicotinoids.

Pharmacological analyses of learning and memory in zebrafish (Danio rerio).

Over the last decade, zebrafish (Danio rerio) have become valuable as a complementary model in behavioral pharmacology, opening a new avenue for understanding the relationships between drug action and behavior. This species offers a useful intermediate approach bridging the gap between in vitro studies and traditional mammalian models. Zebrafish offer great advantages of economy compared to their rodent counterparts, their complex brains and behavioral repertoire offer great translational potential relative to in vitro models.

Zebrafish model systems for developmental neurobehavioral toxicology.

Zebrafish offer many advantages that complement classic mammalian models for the study of normal development as well as for the teratogenic effects of exposure to hazardous compounds. The clear chorion and embryo of the zebrafish allow for continuous visualization of the anatomical changes associated with development, which, along with short maturation times and the capability of complex behavior, makes this model particularly useful for measuring changes to the developing nervous system. Moreover, the rich array of developmental, behavioral, and molecular benefits offered by the zebrafish have contributed to an increasing demand for the use of zebrafish in behavioral teratology.

Dietary nimodipine delays the onset of methylmercury neurotoxicity in mice.

Adult-onset methylmercury (MeHg) exposure is thought to result primarily in sensory and motor deficits but effects on learning are poorly understood. One mechanism by which chronic MeHg may exert its neurotoxicity is via sustained disruption of intracellular calcium homeostasis, with a consequent increase of intracellular Ca(2+) ions in vulnerable neurons. A biochemically heterogeneous group of compounds, calcium channel blockers, have been shown in vitro to attenuate MeHg's toxicity.
