Medical Xpress / People carrying a rare gene variant have naturally low body fat, healthier livers and better blood sugar levels
There are people around us who can maintain their weight despite what they eat. This has led scientists to believe that a person's metabolism and tendency toward obesity may have genetic factors behind them. A large study ...
Medical Xpress / Lonely people can feel their heartbeat clearly like everyone else, but their brains respond differently
For a long time, psychologists have described loneliness as the discomfort that comes from wanting more social connection than we feel we have, but there is more nuance to loneliness. Scientists are increasingly finding that ...
Medical Xpress / Prostate cancer prognosis linked to prostate-specific antigen levels below threshold
After treatment for metastatic prostate cancer, a drop in prostate-specific antigen (PSA) levels in the blood is an indicator that treatment is working. A recent real-world study indicates that reaching a PSA level below ...
Medical Xpress / Unexpected brain mechanism challenges assumptions about GLP-1s
For decades, obesity medications produced only modest weight loss. But in recent years, Ozempic and related GLP-1 therapies have transformed the field, enabling sustained weight loss of 10% to 15% or more. Despite their success, ...
Medical Xpress / Why a doctor saying 'it's normal' can backfire
A new study from the University of California San Diego Rady School of Management suggests that when physicians try to reassure patients by saying their symptoms are "normal," patients may infer that treatment isn't necessary—and ...
Medical Xpress / Simple blood test on a chip could help diagnose lung cancer
Researchers at Tel Aviv University have developed a new method for diagnosing lung cancer: a simple, fast, low-cost blood test that does not require DNA sequencing. The method identifies a chemical fingerprint of cancer cells ...
Medical Xpress / Patient-derived organoids reveal which breast tumors may resist standard therapies
Researchers at UC San Francisco have developed a new method to predict how different types of breast cancer will respond to treatment, using patient data from the I-SPY2 breast cancer trial and rapid testing on lab-grown ...
Medical Xpress / Triple-dose regimen may permanently clear HIV in infected newborns
Every year, more than 120,000 newborns worldwide contract HIV, creating a global health burden that requires lifelong treatment for millions of people—assuming they have access and can afford it. New research led by Oregon ...
Medical Xpress / AI framework decodes how brain regions talk to one another
For decades, neuroscientists have been able to record which parts of the brain show increased electrical activity during a behavior, such as when we form a memory or make a decision. But scientists haven't been able to determine ...
Medical Xpress / Solving a mysterious inflammatory fever opens the book on a much bigger story
Three research teams working independently around the world have landed on the same discovery: A single molecular "handshake" inside our cells controls a family of inflammatory diseases, including one of the most common inherited ...
Medical Xpress / Study reveals growing signs of malaria drug resistance in Ethiopia
Researchers have identified genetic changes in malaria parasites that may reduce the effectiveness of key antimalarial medicines, highlighting the need for continued surveillance.
Medical Xpress / Molecular structures provide roadmap for targeted Parkinson's disease therapeutics
Researchers at Weill Cornell Medicine have uncovered how a key Parkinson's protein called LRRK2 shifts between inactive and active forms, revealing the structural changes that enable certain mutations to push the protein ...
