Application of transcriptomics concentration-response modeling for prioritization of contaminants detected in tributaries of the North American Great Lakes.

As part of the Great Lakes Restoration Initiative, chemical monitoring and surveillance efforts have detected ∼330 chemicals in surface water of Great Lakes tributaries. There were 140 chemicals for which no empirical toxicity data were available. The aim of the present study was to generate transcriptomic points of departure (tPODs) for 10 of these compounds and demonstrate how they could be applied in a screening-level prioritization.

Hair root sonication washing impact on nuclei counts.

In a previous study, hair samples were washed by sonication in Terg-a-zyme™ (Alconox, White Plaines, NY, USA) as part of the DNA extraction protocol. The sonication wash step was deemed necessary in the previous study because the DNA extracts could be used for both mitochondrial (mt) and nuclear(nu) DNA analyses. In the current study, the impact of the sonication wash on the persistence of nuclei was assessed.

Automated QA/QC reporting for non-targeted analysis: a demonstration of "INTERPRET NTA" with de facto water reuse data.

The US Environmental Protection Agency (EPA) uses non-targeted analysis (NTA) to characterize potential risks associated with environmental pollutants and anthropogenic materials. NTA is used throughout EPA's Office of Research and Development (ORD) to support the needs of states, tribes, EPA regions, EPA program offices, and other outside partners. NTA methods are complex and conducted via myriad instrumental platforms and software products.

A combination of high-throughput in vitro and in silico new approach methods for ecotoxicology hazard assessment for fish.

Fish acute toxicity testing is used to inform environmental hazard assessment of chemicals. In silico and in vitro approaches have the potential to reduce the number of fish used in testing and increase the efficiency of generating data for assessing ecological hazards. Here, two in vitro bioactivity assays were adapted for use in high-throughput chemical screening.

Emerging Tools to Support DILI Assessment in Clinical Trials with Abnormal Baseline Serum Liver Tests or Pre-existing Liver Diseases.

Based on the late Dr. Hyman Zimmerman's observation that hepatocellular drug-induced liver injury (DILI) leading to jaundice carries a ≥ 10% fatality risk (coined as Hy's law by others), evaluation of Drug-Induced Serious Hepatotoxicity (eDISH) continues to play a central role in the assessment of a study drug's liability for acute hepatocellular DILI. The eDISH identifies drugs in clinical trials with DILI fatality (death or transplant) risk that may be unacceptable in a post-market setting.

Differential mosaicism of recombinant foot-and-mouth disease viruses resulting from heterologous superinfection of cattle.

Evidence from both field and experimental studies suggests that recombination is a common feature in the evolution of foot-and-mouth disease virus (FMDV). Recent studies have demonstrated that heterologous superinfection of cattle persistently infected with FMDV leads to rapid generation of inter-serotypic recombinant viruses in the upper respiratory tract mucosa. The current study demonstrates that the order of exposure to FMDV strains A24 Cruzeiro and O1 Manisa substantially influenced the patterns of mosaicism of resultant recombinants.

A haplotype-resolved reference genome of Quercus alba sheds light on the evolutionary history of oaks.

White oak (Quercus alba) is an abundant forest tree species across eastern North America that is ecologically, culturally, and economically important. We report the first haplotype-resolved chromosome-scale genome assembly of Q. alba and conduct comparative analyses of genome structure and gene content against other published Fagaceae genomes.

Enhanced survival of mass-reared Mediterranean fruit flies via regular diurnal temperature oscillations.

Effectively mass-rearing insects is critical for research, for environmentally friendly technologies like sterile insect technique, producing biological control agents, and enabling novel pest control methods such as those based on genetics or symbionts. While constant temperature conditions are typically used in mass-rearing, at what is considered an optimum value that produces the fittest insects, homeostatic conditions do not reflect the real world. We investigated the performance of mass-reared adult Ceratitis capitata Wiedemann (Diptera: Tephritidae) under constant (24 °C) and oscillating (mean 24 °C with 4 and 10 °C range) temperature regimes.

Effects of a novel estrogenic perfluoroalkyl substance on reproductive endocrinology and function in the fathead minnow (Pimephales promelas).

Effects data are lacking for the majority of poly- and perfluoroalkyl substances (PFAS). Recent in vitro work with around 140 data-poor PFAS showed that several could affect signaling pathways associated with estrogen receptor-α (ER). Subsequent short-term gene expression studies with adult male fathead minnows (Pimephales promelas) using a subset of the ER-active PFAS confirmed their estrogenic properties in vivo.

Reducing Fire Severity and Extent Bolsters Subalpine Forest Resilience to Global Change Through Key Demographic Pathways.

High-elevation subalpine forests are experiencing rapid changes in climatic conditions, biological disturbances, and wildfire regimes. Despite this, evidence is mixed as to whether they will undergo major ecological transformation or be resilient to a confluence of global change drivers. Here we use subalpine fir (Abies lasiocarpa) and Englemann spruce (Picea engelmannii), which form co-dominant forests through much of the western United States, to investigate how species' demographic responses to global change influence forest community-wide resilience.

Diamide insecticides, specifically chlorantraniliprole (CHL), have been rising in popularity over the past decade, becoming one of the most widely used insecticide classes globally. These insecticides target the ryanodine receptor (RyR), primarily for control of lepidopteran agricultural pests. Field studies have revealed that some lepidopteran species have developed mutations where a methionine in a particular position (e.

Systematic Literature Review on Public Health Impacts of Persistent Tic Disorders: Health Care Needs and Health Care Use.

This study describes our systematic literature review documenting outcomes associated with persistent tic disorders (PTDs) and summarizes 15 articles comparing health care use between individuals with PTDs and a comparison group without PTDs. Only 2 studies included adults and only one study stratified findings by sociodemographic characteristics, precluding conclusions on health care disparities. Most children with PTDs had access to routine care, similar to children without PTDs, but needed and used more specialty health care, including mental health services, compared to children without PTDs.

Development and application of a non-targeted analysis method using GC-MS and LC-MS for identifying chemical contaminants in drinking water via point-of-use filters.

While many chemicals are regulated and routinely monitored in drinking water, they represent just a portion of all contaminants that may be present. Typical drinking water analyses involve sampling one liter or less of water, which could lead to trace level contaminants going undetected. In this study, a method was developed for using point-of-use activated carbon block drinking water filters as sampling devices.

Maternal Exposure to Ozone During Implantation Promotes a Feminized Transcriptomic Profile in the Male Adolescent Liver.

Maternal exposure to ozone during implantation results in reduced fetal weight gain in rats. Offspring from ozone-exposed dams demonstrate sexually dimorphic risks to high-fat diet feeding in adolescence. To better understand the adolescent hepatic metabolic landscape following fetal growth restriction, RNA sequencing was performed to characterize the effects of ozone-induced fetal growth restriction on male and female offspring.

Folate and Vitamin B12 Status among Non-Pregnant, Non-Lactating Women of Reproductive Age and Predicted Risk for Neural Tube Defects, Morogoro Region, Tanzania.

Introduction: Population risk for neural tube defects (NTDs) can be determined using red blood cell (RBC) folate. However, a paucity of biomarker and surveillance data among non-lactating, non-pregnant women of reproductive age (NPWRA) from Africa limits accurate assessment. Our study assessed folate and vitamin B12 status among non-lactating NPWRA and predicted population risk of NTDs in Tanzania.

Purpose: Alzheimer's disease and related dementias (ADRD) are a significant public health concern characterized by memory decline that, over time, leads to loss of independence. This study reports ADRD diagnosis rates among Medicare beneficiaries aged ≥ 65 years in rural America.

Methods: We conducted a descriptive analysis of Medicare Fee-for-Service (FFS) and Medicare Advantage enrollees using administrative Medicare data from 2020.

Transcriptomic response of an algal species (raphidocelis subcapitata) exposed to 22 per- and polyfluoroalkyl substances.

Per- and polyfluoroalkyl substances (PFAS) are a large class of chemicals of concern for both human and environmental health because of their ubiquitous presence in the environment, persistence, and potential toxicological effects. Despite this, ecological hazard data are limited to a small number of PFAS even though there are over 4000 identified PFAS. Traditional toxicity testing will likely be inadequate to generate necessary hazard information for risk assessment.

Morrey Award 2023: radial head donor plug for capitellum osteochondral autograft transfer: a cadaveric biomechanical analysis.

Background: Limitations to using the knee as donor cartilage include cartilage thickness mismatch and donor site morbidity. Using the radial head as donor autograft for capitellar lesions may allow for local graft harvest without distant donor site morbidity. The purpose of this study is to demonstrate the feasibility of performing local osteochondral autograft transfer from the nonarticular cartilaginous rim of the radial head to the capitellum.

Objective: Our study assessed child-serving health care providers' attitudes and knowledge related to identification and treatment of tic disorders including Tourette syndrome (TS), among children.

Methods: We analyzed cross-sectional data from the 2022 Fall DocStyles, a web-based survey of health care providers. The analytic sample included 1058 child-serving providers (403 family practitioners, 232 internists, 251 pediatricians, and 172 nurse practitioners or physician assistants).

Immune responses of cattle vaccinated by various routes with Mycobacterium bovis Bacillus Calmette-Guérin (BCG).

Background: Mycobacterium bovis BCG is the human tuberculosis vaccine and is the oldest vaccine still in use today with over 4 billion people vaccinated since 1921. The BCG vaccine has also been investigated experimentally in cattle and wildlife by various routes including oral and parenteral. Thus far, oral vaccination studies of cattle have involved liquid BCG or liquid BCG incorporated into a lipid matrix.

Carbohydrate supplementation maintains physical performance during short-term energy deficit despite reductions in exogenous glucose oxidation.

Exogenous glucose oxidation is reduced 55% during aerobic exercise after 3 days of complete starvation. Whether energy deficits more commonly experienced by athletes and military personnel similarly affect exogenous glucose oxidation and what impact this has on physical performance remains undetermined. This randomized, longitudinal parallel study aimed to assess the effects of varying magnitudes of energy deficit (DEF) on exogenous glucose oxidation and physical performance compared with energy balance (BAL).
