(Press-News.org) In a recent publication released by PubMed, American scientist Dr. Renee Dufault at the Food Ingredient and Health Research Institute, provides a peer-reviewed protocol for determining the role ultra-processed foods play in prenatal heavy metal exposures and changes in the expression of the zinc dependent MT-1 (metallothionein) gene that impact child neurodevelopment. Previous biomarker studies show dietary zinc deficits impact metallothionein protein levels and are associated with the bioaccumulation of lead and/or mercury in children with symptoms associated with autism and attention deficit/hyperactivity disorders. This protocol builds on the results of previous clinical trial research and provides valid and reliable methods for measuring changes in ultra-processed food intake and diet pre-post administration of nutritional epigenetics education. The impact of dietary changes on lead and mercury exposures and MT gene behavior would be determined using a randomized test and control group design. Pregnant women serving in the test group would participate in the nutritional epigenetics education intervention designed to reduce ultra-processed food intake and heavy metal levels in blood while increasing whole food intake and MT and zinc levels. Changes in maternal lead mercury, zinc, and metallothionein levels would be measured via blood sample analyses prior to the nutritional epigenetics education intervention and after childbirth via cord blood analyses to determine infant risk factors for the development of autism and/or attention deficit/hyperactivity disorders.
The line of research that focuses on the effect of dietary factors on gene expression is known as nutritional epigenetics. Dr. Dufault’s has led research efforts in this field of study since 2005 when she first identified the problem of inorganic mercury residues in high fructose corn syrup while still working at the Food and Drug Administration.
Heavy metal residues continue to be a problem in the food supply. The US Congress released two reports in 2021 on the problem of heavy metals in baby foods. The first report issued on February 4, 2021, revealed baby foods are tainted with dangerous levels of arsenic, lead, cadmium, and mercury. The second report, issued on September 29, 2021, confirmed new disclosures from manufacturers show dangerous levels of heavy metals in even more baby foods. These heavy metal exposures may further exacerbate the development of autism and ADHD.

Feeling mental exhaustion? These two areas of the brain may control whether people give up or persevere
2025-06-26
FOR IMMEDIATE RELEASE
Key Takeaways:
Two areas of the brain may work in combination to tell the brain when it’s “feeling” tired.
People with depression and post-traumatic stress disorder (PTSD) often experience cognitive fatigue.
Results of the study may provide a way for physicians to better evaluate and treat people who experience such fatigue.
In experiments with healthy volunteers undergoing functional MRI imaging, scientists have found increased activity in two areas of the brain that work together to react to, and possibly regulate, the brain when it’s “feeling” ...
Genomes from people across modern-day India shed light on 50,000 years of evolutionary history
2025-06-26
India’s population is genetically one of the most diverse in the world, yet it remains underrepresented in global datasets. In a study publishing in the Cell Press journal Cell, researchers analyzed genomic data from more than 2,700 people from across India, capturing genetic variation from most geographic regions, linguistic groups, and communities. They found that most modern-day Indian people’s ancestry can be traced back to Neolithic Iranian farmers, Eurasian Steppe pastoralists, and South Asian hunter-gatherers.

Muscle in space sheds light on ageing-related muscle loss
2025-06-26
Sarcopenia, which is a progressive and extensive decline in muscle mass and strength, is common with aging and estimated to affect up to 50% of people aged 80 and older. It can lead to disability and injuries from falls and is associated with a lower quality of life and an increased mortality. Apart from lifestyle changes, there is no current clinical treatment for sarcopenia.
Space flight with the associated absence of gravity and limited strain on muscles causes muscle weakness, a prominent feature of sarcopenia, within a short period of time, providing a time lapse view on age-related atrophy-associated ...
Availability of medications for opioid use disorder in opioid treatment programs
2025-06-26
About The Study: In this cross-sectional study of opioid treatment programs (OTPs), although the availability of medications for opioid use disorder (MOUD) beyond methadone increased over time, most OTPs still did not offer all 3 forms of MOUD as of 2023. Specific organizational characteristics, such as being government operated and accepting Medicare, were associated with more comprehensive MOUD offerings. Future research should evaluate why OTPs vary in their MOUD offerings.

Receipt of buprenorphine and naltrexone for opioid use disorder by race and ethnicity and insurance type
2025-06-26
About The Study: In this cohort study of opioid-related index health care events, race and ethnicity–based and insurance-based disparities in access to medications for opioid use disorder persisted despite efforts to expand treatment availability. These findings underscore the need for targeted interventions, including culturally tailored care, expanded access points, and policy reforms to address structural barriers and reduce inequities contributing to the overdose crisis.

Scientists complete the most thorough analysis yet of India's genetic diversity
2025-06-26
With around 5,000 different ethno-linguistic and religious groups, India is one of the most culturally and genetically diverse countries in the world. Yet, it remains underrepresented in genomic surveys, even when compared to other non-European groups, such as East Asians and Africans.
A new analysis of Indian genomes — the largest and most complete to date — helps untangle these groups' complex evolutionary history, uncovering a 50,000-year history of genetic mixing and population bottlenecks that shaped genetic variation, ...
