Teeth may seem like static fixtures, but a new collaboration between engineers and clinicians is proving just how dynamic, informative and medically significant our teeth can be.

Over the past decades, childhood obesity has become a global health crisis, intensified by the sedentary routines and dietary disruptions of the COVID-19 pandemic.

Severe fever with thrombocytopenia syndrome (SFTS) was reported in Asia, with a fatality rate that can reach as high as 50%.

Ovarian aging, characterized by diminishing egg reserves and quality, affects millions of women worldwide, often leading to infertility.

Intratumoral microbiota-the microbial populations residing within solid tumors-have emerged as pivotal components of the tumor microenvironment (TME), influencing tumor initiation, progression, and therapeutic outcomes.

Sepsis is a life-threatening condition caused by organ dysfunction resulting from the body's dysregulated response to infection.

Age-related macular degeneration (AMD) remains a leading cause of vision loss globally, with significant advancements in treatment options for both dry and wet AMD.

Pain is an important physiological response in living organisms. While physical pain is an outcome of tissue damage, pain can manifest as diverse unpleasant sensory and emotional experiences. Many studies report that emotional or psychological stress enhances pain responses.

Diabetes affects millions worldwide, causing both nerve and metabolic complications. A recent study suggests that diabetic nerve damage may also lead to impaired bone health.

Acute liver failure (ALF) represents a life-threatening condition marked by rapid deterioration of liver function, often necessitating urgent liver transplantation.

Digestive system malignancies (DSMTs)-including esophageal, gastric, colorectal, liver, and pancreatic cancers-represent a major public health challenge in China.

Cuproptosis represents a novel mechanism of cell death characterized by intracellular copper ion accumulation.

An experimental mRNA vaccine boosted the tumor-fighting effects of immunotherapy in a mouse-model study, bringing researchers one step closer to their goal of developing a universal vaccine to "wake up" the immune system against cancer.

As millions of people know firsthand, the most common side effect of mRNA vaccines like the COVID-19 shot is inflammation: soreness, redness and a day or two of malaise.

A new study sponsored by Mirvie, which is the first to evaluate U.S. Preventive Services Task Force (USPSTF) guidelines for preeclampsia risk and aspirin prescription in a single, nationally representative, prospective population, found while high-risk factors had sufficient value in estimating risk, there's limited value for the moderate risk category - leading to nonspecific recommendations for aspirin use, a recognized prevention tool.

Two junior research groups at Ruhr University Bochum, Germany, have developed a drug complex that kills cancer cells in such a clever manner that they raise a red flag as they die. They signal to the immune system that something is seriously wrong with this type of cell.

In a major advance for patients with Crohn's disease, a new study led by researchers at Mount Sinai Health System found that guselkumab, a medication with a mechanism of action that is new to inflammatory bowel disease (IBD) treatment, outperformed an established standard of care in promoting intestinal healing and symptom relief.

Vitamin D is not only an essential nutrient, but also the precursor of the hormone calcitriol, indispensable for health: it regulates the uptake of phosphate and calcium necessary for bones by the intestines, as well as cell growth and the proper function of muscles, nerve cells, and the immune system.

Patients with heart failure and atrial fibrillation (AF) at the time of mitral transcatheter edge-to-edge repair (M-TEER) for severe mitral regurgitation are more than twice as likely to die or be rehospitalized for heart failure, compared to patients without AF.

"Complex processes are going on in the brain when we sleep," says Dr Karolina Armonaitė, a neuroscientist from Kaunas University of Technology, Lithuania. According to her, a more precise understanding of what happens in different areas of the cerebral cortex during sleep can help diagnose sleep disorders and neurological diseases more accurately.
