Live tracking reveals how robotic surgery impacts surgeon stress

Robot-assisted surgery (RAS) is one of the most advanced tools in modern medicine. These systems give surgeons extreme precision, allowing procedures to be performed through small incisions that minimize both pain and recovery time.

Risk-adapted frameworks reshape pediatric neuroblastoma care

Neuroblastoma is the most common solid tumor outside the brain in children younger than five years old and accounts for about 15% of pediatric cancer deaths.

Genetic changes in zebrafish reveal new pathways for back pain

Neck and back pain could be caused by changes in gene activity that trigger the breakdown of the spine's natural shock absorbers, new research suggests.

Older men’s sexual priorities extend well beyond erectile function

A web-based survey of 6,000 Japanese men aged 50 or older found that sexual arousal was the function they most wanted to preserve, while erection became more highly valued as erectile function worsened. Erection showed the earliest age-related decline pattern, whereas ejaculation was the function most often reported as lost in older age.

Nerve-blocking therapy improves growth plate repair in injured bones

With the support of National Institutes of Health funding, Johns Hopkins Medicine investigators, led by pathologist Aaron W. James, M.D., Ph.D., previously discovered that sensory neurons in skeletal tissue are constantly sensing their environment and are quick to respond to injuries.

Discovery may help develop new treatments for immunosuppressed skin cancer patients

Researchers at The University of Texas MD Anderson Cancer Center have discovered that immunosuppressed patients with non-melanoma skin cancer are not missing the key cancer-fighting immune cells found in immunocompetent patients, but those cells – known as macrophages – have lost the ability to communicate effectively.

Tumor-secreted protein makes lung blood vessels leaky to promote 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 Center.

NIH funds research to explore the role of thymulin in inflammaging and cancer

As we age, chronic inflammation-or "inflammaging"-increases throughout the body and weakens our ability to fight cancer.

Study shows effectiveness of surgical treatment for chronic rhinosinusitis with nasal polyps

Both full and limited endoscopic sinus surgery significantly improve quality of life in patients with chronic rhinosinusitis with nasal polyps, according to a recent study published in Allergy.

Ketamine boosts neuroplasticity through microglia in female brains

Doctors use ketamine on patients as general anesthesia before surgery. They also prescribe it in low doses for pain management, and more recently, it's been used for treatment-resistant depression where other drugs have failed.

TRF2 protein preserves muscle stem cell identity and regeneration

A protein best known for protecting the ends of chromosomes also helps muscle stem cells preserve their identity and repair damaged tissue, according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania.

Brain immune cells drive recovery from ketamine anesthesia in females

During ketamine anesthesia, the brain's nerve cells fall silent-as consciousness returns, they begin to reconnect.

Researchers propose new framework to define clinical obesity

A new approach to defining obesity could help physicians better determine which patients need more intensive treatment by focusing on the effects of excess adiposity on organs and tissues rather than relying primarily on whether a person meets a set of metabolic risk thresholds.

New stem cell vesicles accelerate diabetic wound healing

Diabetic foot ulcers are among the most serious complications of diabetes because prolonged inflammation, poor circulation, and defective angiogenesis can leave wounds open for months and increase the risk of infection and amputation.
