Medical Xpress / A new drug that can potentially overcome cancer therapy resistance
Researchers at Baylor College of Medicine have developed a drug called CS18 that disrupts cancer cells' ability to survive therapy. The findings, published in Science Advances, support exploring the possibility of using CS18 ...
Medical Xpress / A lesser-known SARS-CoV-2 protein may offer clues to long COVID symptoms
Six years after the height of the COVID-19 pandemic, scientists are still uncovering surprising ways the virus can wreak havoc on the body. A new UCLA study published in Science Advances describes a previously unrecognized ...
Medical Xpress / Severe COVID-19 reactivates dormant viruses, study finds
Chronically infecting viruses—such as Epstein-Barr virus, cytomegalovirus (CMV) and herpesviruses—are common and often innocuous and asymptomatic. However, emerging evidence suggests their reactivation may contribute to autoimmune ...
Medical Xpress / Why do people's pupils dilate when they're surprised? Researchers explain
When people encounter new information that challenges their expectations, their pupils are likely to dilate. This physiological response is a sign that something is happening in the brain to help the person adapt to the new ...
Medical Xpress / A 'molecular switch' that heals the gut—and that colorectal cancer hijacks to spread
Digestion is hard on the cells that line the human gut, and they are constantly being shed and replaced. This renewal is driven by a population of tireless stem cells. These stem cells can both replace the various types of ...
Medical Xpress / Study uses living human brain tissue to map how electric stimulation affects neurons and genetic activity
Neurons that once encoded a person's memories are now helping researchers identify genetic targets that may one day help preserve memory and slow cognitive decline in others.
Medical Xpress / Common neuroscience sensors sometimes get their signals crossed
Cells in the brain communicate in different ways. The classical mode involves tight connections between individual cells that signal only to each other. But over the last decade, new tools have allowed scientists to focus ...
Medical Xpress / Structural studies reveal how lipid-transport proteins may influence neurodegenerative disease
Researchers at Yale School of Medicine have conducted the first comprehensive structural analyses of a class of proteins whose dysfunction is associated with neurodegenerative diseases.
Medical Xpress / Language models identify psychiatric symptoms nearly as accurately as early-career clinicians
A study led by the Central Institute of Mental Health (CIMH) provides initial evidence that large language models can identify complex psychopathological findings in transcripts of psychiatric interviews with accuracy comparable ...
Medical Xpress / New model maps where HIV is concentrated and the disease is more advanced
A new biostatistical modeling approach has the potential to support health decisions by pinpointing where HIV is concentrated and where people living with HIV are showing signs of severe immune suppression or delayed treatment. ...
Medical Xpress / IL-1 pathway may stop Candida fungus from turning fatal in weakened immunity
An immune pathway has been discovered that prevents a normally harmless fungus from developing into a fatal infection. The King's College London study, published in Nature Microbiology, provides the first potential clue as ...
Medical Xpress / Tumor-secreted protein makes lung vessels leakier, promoting metastasis
A protein secreted by common cancer types makes blood vessels leakier to allow metastatic tumors to form in the lungs, according to a study led by investigators at Weill Cornell Medicine and Memorial Sloan Kettering Cancer ...
