Marshall University awarded grant to further fentanyl addiction research

2024-07-19
(Press-News.org) HUNTINGTON, W.Va. – Marshall University was awarded a $3.3 million grant (#R01DA057931) from the National Institute on Drug Abuse (NIDA) to examine the genetic mechanisms that underlie fentanyl addiction.  

In 2022, fentanyl overdose was the leading cause of death for U.S. adults aged 18 to 45, according to Families Against Fentanyl (2023).  

“This alarming statistic highlights the urgent need to understand why some people are more susceptible to fentanyl addiction,” said Price E. Dickson, Ph.D., assistant professor of biomedical sciences at the Marshall University Joan C. Edwards School of Medicine and lead investigator of this five-year study. “Identifying how certain genes influence the brain’s response to fentanyl will pave the way for the development of effective treatments, thus addressing a critical public health need.” 

According to the incentive sensitization theory of addiction, repeated drug use can make the brain’s reward system overly sensitive to drug-related cues, leading to a powerful craving for the drug. While both fentanyl addiction and incentive sensitization are known to be highly inheritable in humans and mice, the specific genetic mechanisms linking incentive sensitization to fentanyl addiction have remained elusive.  

Dickson and his team will use a panel of genetically diverse mice in concert with advanced neurogenomics and neuroscience approaches to discover the genes and brain mechanisms that underlie vulnerability and resistance to fentanyl addiction. Co-investigators Brandon J. Henderson, Ph.D., and Alejandro Q. Nato Jr. Ph.D., both associate professors of biomedical sciences at Marshall University, will bring expertise in neuroscience, bioinformatics and statistical genetics. 

Ultimately, this pioneering research may result in the development of novel, more effective addiction treatments and, in so doing, address a critical need in public health.  

An R01 research grant is a prestigious funding mechanism through the National Institutes of Health and its affiliated institutes and centers that supports health-related research projects. Securing this highly competitive grant signifies recognition of the project's scientific merit and its potential impact on advancing medical knowledge and improving public health.

Wash U researchers shine light on amyloid architecture

2024-07-19
By Leah Shaffer Amyloid-beta (A-beta) aggregates are tangles of proteins most notably associated with neurodegenerative diseases like Alzheimer’s. Despite its constant stint in the limelight, however, researchers have been unable to get a good understanding of how A-beta comes together and breaks apart. “The way A-beta behaves in a variety of environments, including the human brain, is elusive,” said Brian Sun, an electrical systems and engineering alumnus of Washington University in St. Louis who is now an MD/PhD student in the School of Medicine. “There’s an understanding of growth and decay that isn’t ...

New dawn for space storm alerts could help shield Earth's tech Royal Astronomical Society press release RAS PR 24/22 (NAM 8) For immediate release   Space storms could soon be forecasted with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth. Scientists say it is now possible to predict the precise speed a coronal mass ejection (CME) is travelling at and when it will smash into our planet – even before it has fully erupted from ...

Tomorrow’s super battery for electric cars is made of rock

Tomorrow’s super battery for electric cars is made of rock
2024-07-19
In 10 years, solid-state batteries made from rock silicates will be an environmentally friendly, more efficient and safer alternative to the lithium-ion batteries we use today. Researcher at DTU have patented a new superionic material based on potassium silicate - a mineral that can be extracted from ordinary rocks. It is the battery in your electric car that determines how far you can drive on one charge and how quickly you can re-charge. However, the lithium-ion battery, the most widely used electric car battery today, has its limitations— in terms of capacity, safety and also availability. ...

Fecal immunochemical test screening and risk of colorectal cancer death

2024-07-19
About The Study: In this nested case-control study, completing fecal immunochemical test was associated with a lower risk of overall death from colorectal cancer, particularly in the left colon, and the associations were observed across racial and ethnic groups. These findings support the use of fecal immunochemical test in population-based screening strategies.  Corresponding Author: To contact the corresponding author, Chyke A. Doubeni, M.D., M.P.H., email chyke.doubeni@osumc.edu. To access the embargoed ...

Long-term use of oral corticosteroids and safety outcomes for patients with atopic dermatitis

2024-07-19
About The Study: Oral corticosteroid use of more than 90 days per year among individuals with atopic dermatitis was associated with a small increased risk of composite adverse outcomes in this large population-based case-control study. Future investigations are warranted to confirm this potential risk of adverse events (AEs) associated with long-term use of oral corticosteroids for patients with exacerbations of atopic dermatitis, and health care professionals should thoroughly weigh the benefits associated with oral corticosteroids ...

Diagnosing solid lesions in the pancreas with multimodal AI

2024-07-19
About The Study: In this randomized crossover trial of diagnosing solid lesions in the pancreas with or without artificial intelligence (AI) assistance, the joint-AI model demonstrated positive human-AI interaction, which suggested its potential to facilitate a clinical diagnosis. Nevertheless, future randomized clinical trials are warranted. Corresponding Authors: To contact the corresponding authors, email Aiming Yang, M.D. (yangaiming@medmail.com.cn) and Bin Cheng, M.D. (b.cheng@tjh.tjmu.edu.cn).

Trillions lost in worker productivity due to eco anxiety and ‘lie-back’ lifestyles

2024-07-19
Could nature and climate anxieties predict future social behaviours, in the same way that consumer sentiment predicts purchasing and investment?    The suggestion is made in the Cell Press journal One Earth, by Griffith University’s Professor Emeritus Ralf Buckley, in a preview of an article led by Professor Thomas Pienkowski in the UK.    Professor Buckley said the international Global Burden of Disease Study had shown that anxiety and depression were widespread and worsening.   “Economic costs are up to 16% of global GDP, with 19 days per year on average lost ...

University of Cincinnati study examines impact of incarceration on youth health

University of Cincinnati study examines impact of incarceration on youth health
2024-07-19
Researcher Samantha Boch has studied the impact of incarceration on child and family health for more than a decade. Her latest research examines the health records and health care use of youth, individuals under age 21, who likely have been involved or whose families have been involved in the justice system. The challenge was identifying youth who have been impacted by mass incarceration, as most health care systems don’t routinely ask about incarceration. Families may not disclose that information due to stigma, fear of child protective services involvement, ...

This innovative approach provides detailed elevation data and vegetation analysis, enabling highly accurate classifications of diverse wetland types. The research advances conservation by offering a scalable, efficient, and cost-effective method that is instrumental in climate change mitigation strategies and informs policy-making for coastal resilience. Coastal wetlands, situated at the junction of land and water, are vital ecosystems known for their high productivity. They play a key role in carbon ...

New discovery adds to story of ancient human migration

2024-07-19
New evidence of human occupation in southeast Indonesia dating back 42,000 years offers fresh clues on the route taken by some of the first humans to arrive in our region, according to a study from The Australian National University (ANU).  Lead author and ANU PhD candidate Hendri Kaharudin said the location of the discovery -- at Elivavan on Indonesia’s Tanimbar islands -- makes it especially significant.   “Tanimbar is located just off the ‘Sahul shelf’, which encompasses modern-day Australia, as well as New Guinea,” he said.  “The question ...
