Gut bioelectricity provides a path for bad bacteria to cause diseases

A team of researchers at UC Davis Health discovered a novel bioelectrical mechanism that allows Salmonella bacteria to navigate the gut lining and find vulnerable entry points. The study found that Salmonella bacteria detect electric signals in FAE, which helps them move towards openings in the gut where they can enter.

Study shows donor kidneys with toxoplasma do not increase risks for transplant patients

Researchers analyzed 51,000 transplants and found rejection and graft failure rates were similar for toxoplasma-positive and negative donor kidneys. The study suggests it is safe to transplant toxoplasma-positive kidneys with additional monitoring, potentially increasing the supply of donor kidneys.

Researchers find key differences in brain development between autistic boys and girls

A new study found significant differences in brain development between autistic boys and girls, with autistic females showing a thicker cortex at age 3 and faster cortical thinning into middle childhood. The findings highlight the need for longitudinal studies that include both sexes to better understand sex-specific changes in autism.

Study finds biomarkers for psychiatric symptoms in patients with rare genetic condition 22q

A recent study led by UC Davis Health researchers provides new insights into the molecular changes linked to 22q11.2 deletion syndrome, a rare genetic condition that can lead to psychosis, ADHD, and other conditions. The study identified two biomarkers, taurine and arachidonic acid, which could predict likelihood of psychosis in patien...

New study points to racial and social barriers that block treatment for multiple myeloma

A recent study by the University of California - Davis Health found that racial and social barriers significantly impact access to autoHCT, a key bone marrow transplant treatment for multiple myeloma. Despite having higher rates of cancer development compared to other groups, Black patients received lower proportions of the transplant ...

Human brains are getting larger. That may be good news for dementia risk

A new study found that human brains are getting larger, with participants born in the 1970s having 6.6% greater brain volume and almost 15% larger brain surface area than those born in the 1930s. This increased brain size may lead to a higher brain reserve, potentially reducing the overall risk of age-related dementias.

How firearms move from legal purchase to criminal use

A new study analyzing California gun data found that guns lost or stolen are three times more likely to be used in a crime, while cheap, semiautomatic, and large caliber handguns are also at higher risk. The study suggests securing firearms from theft or loss should be a primary focus for preventing firearm-related crimes.

Loss of executive function may signal onset of neurodegenerative condition FXTAS

Researchers at UC Davis found that men with FMR1 premutation who experienced reduced executive function were at higher likelihood of developing fragile X-associated tremor/ataxia syndrome. Executive function challenges, particularly working memory and organization issues, were strongly associated with the development of FXTAS.
