Medical Xpress / AI-electrocardiogram model developed to diagnose liver disease earlier
As rates of obesity, high blood pressure, type 2 diabetes and sleep apnea increase, cases of advanced chronic liver disease and resulting liver scarring or cirrhosis also are rising. Patients are often diagnosed based on ...
Medical Xpress / AI in primary care: Experts warn of safety risks as tech outpaces regulation
From digital scribes to ChatGPT, artificial intelligence (AI) is rapidly entering GP clinics. New University of Sydney research warns that technology is racing ahead of safety checks, putting patients and health systems at ...
Medical Xpress / 3D bioprinting offers alternative to animal testing for skin disease research
At TU Wien, researchers are developing three-dimensional (3D) printing techniques that can be used to create living biological tissue—for example, to study skin diseases.
Medical Xpress / Psilocybin shows greater potential than cannabinoids for obsessive-compulsive disorder treatment
In a review of previous studies, McMaster University researchers observe a stronger signal for psilocybin as a treatment for obsessive-compulsive disorder than cannabinoids.
Medical Xpress / Mapping pre-myelinating oligodendrocytes: New mouse line links neuronal activity to cell survival
Nerve fibers in the brain and spinal cord are wrapped in an insulating sheath known as myelin. For a long time, this barrier, which is essentially the brain's white matter, was believed to serve the main function of speeding ...
Medical Xpress / Not everyone reads the room the same: Some brains perform a complicated assessment—while others take a shortcut
Are you a social savant who easily reads people's emotions? Or are you someone who leaves an interaction with an unclear understanding of another person's emotional state?
Medical Xpress / Stress hormone identified that helps repair the brain
When laboratory mice suffer brain damage, e.g., from an injection, research group leader Jan Deussing has observed that a certain type of cell always appears and is activated in the immediate vicinity of the injury site. ...
Medical Xpress / Alcohol-linked DNA damage tied to cancer risk: Study reveals repair enzyme's role
Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA. A research team from IOCB Prague has now described in detail how cells repair this damaged genetic information.
Medical Xpress / 40% of MRI signals do not correspond to actual brain activity, study suggests
For almost three decades, functional magnetic resonance imaging (fMRI) has been one of the main tools in brain research. Yet a new study published in Nature Neuroscience fundamentally challenges the way fMRI data have so ...
Medical Xpress / Researchers discover bias in AI models that analyze pathology samples
Pathology has long been the cornerstone of cancer diagnosis and treatment. A pathologist carefully examines an ultrathin slice of human tissue under a microscope for clues that indicate the presence, type, and stage of cancer.
Medical Xpress / Harmless Klebsiella strain shows powerful protection against gut infections in inflammatory bowel disease model
A team of researchers led by Karina Xavier has uncovered a promising new live biotherapeutic agent that may redefine how the medical field approaches microbiota-based therapies.
Medical Xpress / AI model helps diagnose often undetected heart disease from simple EKG
Doctors may soon be able to diagnose an elusive form of heart disease within seconds by using an AI model developed at University of Michigan, according to a recent study.
