New PET tracer offers a powerful tool for kidney cancer staging

A new PET tracer targeting carbonic anhydrase IX (CAIX) has demonstrated exceptional sensitivity and high tumor-to-background contrast in detecting clear cell renal cell carcinoma (ccRCC), according to early clinical research.

Novel PRRT approach shows promise in advanced neuroendocrine tumors

A new type of peptide receptor radionuclide therapy (PRRT) appears to be safe in metastatic neuroendocrine tumor patients who have exhausted conventional treatment options.

New mathematical model tracks microbial contribution to human digestion

Food labels make calories seem simple. They show the number of calories per serving, which is calculated based on how much fat, carbohydrates and protein the food contains.

Persistent gut microbiome changes linked to sustained colorectal cancer risk

More than a decade after removal of an adenoma-a precancerous mass-from the colon, alterations to the gut microbiome and metabolites remain and may drive heightened risk of colorectal cancer (CRC), according to a new study led by researchers at Harvard T.H. Chan School of Public Health.

Cincinnati scientists grow larger gut organoids with self-developing nerve cells

Thanks to special 3D-printed scaffolding trays designed by experts at Cincinnati Children's, researchers can now produce larger versions of functional human gut organoids twice as fast as previous methods-and these organoids grow their own nerve cells.

New vaccine approach targets broad protection against arenavirus infections

Scientists at La Jolla Institute for Immunology (LJI) have discovered that combining key vaccine ingredients could give the body the tools it needs to fight the entire family of arenaviruses with a single vaccine.

Dangerous water bead ingestions increase among young children

A new study reveals that ingestions of water beads by young children have surged in recent years. Researchers at the Center for Injury Research and Policy of the Abigail Wexner Research Institute at Nationwide Children's Hospital and the Central Ohio Poison Center analyzed calls to U.S. poison centers and found an alarming 6,532% increase in the rate of reported water bead ingestions among children younger than 6 years from 2019 to 2023, followed by a 24% decrease from 2023 to 2024.

Microbial "signatures" within the oral cavity and gut may aid in gastric cancer detection

A recent study published in Cell Reports Medicine has identified distinct microbial "signatures" within the oral cavity and gut that serve as robust biomarkers for the early detection of gastric cancer (GC).

EV-RNAs show promise for IBD diagnosis and treatment

A research team led by Sir Run-Run Shaw Hospital, Zhejiang University School of Medicine, has published a comprehensive review in ExRNA that sorts out the diverse roles of extracellular vesicle-associated RNAs (EV-RNAs) in the development and progression of inflammatory bowel disease (IBD).

Sylvester Comprehensive Cancer Center opens new trial for neuroendocrine tumors

A clinical trial for patients with high-grade neuroendocrine tumors is now open for enrollment at Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine.

New target identified to overcome resistance in neuroendocrine tumors

Neuroendocrine cells are unique in their ability to act both as nerve cells and hormone-making cells.

Toxic RNA drives progressive heart damage in myotonic dystrophy

Myotonic dystrophy type 1 (DM1) is the most common cause of adult-onset muscular dystrophy, a genetic disorder that leads to muscle weakness and wasting, but also affects the brain, the gastrointestinal tract and the heart.

New stem cell therapy offers permanent cure for Hirschsprung disease

Scientists are developing a revolutionary new stem cell therapy to treat a rare and life-threatening disease that leaves newborn babies unable to function without invasive surgery, thanks to a collaboration between UCL, the University of Sheffield and Queen's University Belfast.

Parasites trigger a gut-to-brain signal that cuts food intake during infection

Researchers found that intestinal tuft cells signal to crypt enterochromaffin cells by releasing acetylcholine, triggering serotonin release and activating a gut-to-brain vagal pathway during type 2 inflammation. This sustained signalling, rather than the initial acute response, was linked to reduced food intake in mouse models of parasitic infection.

Advanced endoscopic technique successfully treats early-stage colorectal cancer

In the months before his wedding, Queens resident Roberto Pineda Sanchez noticed persistent rectal bleeding, a dangerous symptom he almost ignored.

Why do some people respond better to GLP-1 drugs? Gut microbiome may hold clues

A review in the Canadian Journal of Physiology and Pharmacology examines emerging evidence linking glucagon-like peptide-1 receptor agonists (GLP-1 RAs), the gut microbiome, and obesity treatment outcomes. The authors conclude that microbiome changes seen during therapy are most likely driven by diet, behavior, and weight loss, although microbial profiling may eventually help predict patient responses.

How the aging gastrointestinal tract drives age-related cognitive decline

We become forgetful as we age. This is often seen as a universal truth, but in fact it is far from universal: some people remain incredibly sharp at 100 years old, while others experience memory loss starting in middle age.

Gut microbiome-produced nicotinic acid protects colon tissue from injury

The gut microbiome-the trillions of bacteria and other microbes that inhabit the gastrointestinal tract-drives a process vital for protecting the colon against tissue injury, according to the findings of a study co-led by Cedars-Sinai Health Sciences University investigators.
