High cholesterol leads to long-term liver scarring and immune cell dysfunction in lab study

A lab study found that high cholesterol intake worsens fatty liver disease progression by driving inflammation and scarring. The researchers also discovered long-lasting dysfunction in immune cells responsible for fighting liver damage. Moderation is key to maintaining a healthy diet, according to the study's findings.

Study reveals molecular brain changes linked to APOE4, the main susceptibility gene for Alzheimer’s disease

A new study from USC researchers uncovers the sequence of early molecular changes caused by APOE4, a discovery that may help identify potential treatment targets in the brain's blood vessels. The research reveals problems with the blood-brain barrier and synapses, leading to behavioral deficits and cognitive dysfunction.

New flavored nicotine gums, lozenges, and gummies rank second among nicotine products used by U.S. teens

A study by researchers at Keck School of Medicine found that flavored oral nicotine products, such as gum and gummies, are increasingly popular among US teens, with 3.4% having used them at least once and 1.7% in the past six months. The use of these products was more common among Hispanic teens, teen girls, and LGBTQ+ teens.

Large-scale study of disordered eating in children explores role of weight, sex and puberty

A large-scale study of nearly 12,000 children aged 9-10 found that disordered eating behaviors are more common than previously thought, with a prevalence of up to 5% in some cases. Children with higher BMIs and those further along in puberty face an elevated risk, highlighting the need for targeted prevention efforts.

How did vertebrates first evolve jaws?

Scientists studied embryonic development in fish and cartilaginous fish, revealing that the jaw shares a common developmental origin with the gill. The findings support the theory that the jaw evolved by modification of an ancestral gill, which was previously considered controversial.

Major expansion of open-source neuroimaging data set to boost stroke recovery research

A newly expanded data set of brain scans from stroke patients called ATLAS now includes 1,271 MRI images with manually segmented lesions, facilitating large-scale stroke recovery research. Researchers hope to develop algorithms to automate lesion segmentation, enabling clinicians to predict patient responses to therapies.

Groundbreaking study shows substantial differences in brain structure in people with anorexia

A new study by an international group of researchers has found substantial reductions in grey matter in people with anorexia nervosa, a condition characterized by severe food restriction and low body weight. Early intervention and treatment can help the brain repair itself, according to the research team led by Dr. Paul M. Thompson.

Synthetic “forever chemicals” known as PFAS linked to liver damage

A new study systematically reviews data on PFAS exposure and liver damage, linking three commonly detected PFAS to elevated levels of a liver enzyme, ALT. The research suggests a potential link between PFAS and non-alcoholic fatty liver disease (NAFLD), a growing public health crisis affecting 25% of adults worldwide.

Reducing air pollution could lower dementia risk

A new study found that reducing air pollution can lower dementia risk among older women by decreasing their likelihood of developing dementia. The benefits were consistent despite differences among participants in age, geographic area, socioeconomic background, and other factors.

Fast-tracked stroke drug for humans shows promise, in mice, that it might also prove a powerful tool against dementia

A new study published in the Journal of Experimental Medicine showed that a fast-tracked stroke drug, 3K3A-APC, protected mice from injury to the brain's white matter, a leading cause of dementia. The drug may also be effective in slowing down progression of cognitive impairment.

How alike are the cancer cells from a single patient?

A new study by USC researchers uses a genetic technology to analyze gene expression signatures of individual cancer cells from patients with leukemia. The findings show that cancer cells with distinct gene expression profiles tend to grow in different organs, while those with specific genes are more resistant to chemotherapy.
