Whole-body imaging reveals where drugs bind at single-cell resolution

When you take a drug, where in your body does it actually go? For most medications, scientists can make only educated guesses about the answer to this question.

Remodeling the tumor microenvironment to unlock CAR-T cell potential

Chimeric antigen receptor T (CAR-T) cell therapy has revolutionized hematologic cancer treatment, but its efficacy in solid tumors remains limited by poor infiltration into the complex tumor microenvironment (TME).

Splicing regulator U2AF1 promotes angiogenesis in cardiac injury

A study published in Engineering shows that a protein called U2 small nuclear RNA auxiliary factor 1 (U2AF1), released by immune cells known as macrophages, helps grow new blood vessels in the heart after a myocardial infarction (MI) by altering how the gene Yap1 is spliced.

ACE2 protein may play a protective role against high blood pressure and type 2 diabetes

A collaborative study from the MRC Laboratory of Medical Sciences (LMS) and Imperial College London has found that the protein ACE2 may play a protective role against two common conditions, high blood pressure and type-2 diabetes, which affect millions of people worldwide.

Mucus-inspired hydrogel resists stomach acid and promotes gastrointestinal healing

The Hong Kong Polytechnic University (PolyU) has developed an acid-resistant "ultra-stable mucus-inspired hydrogel" (UMIH), marking a breakthrough in the field of gastrointestinal medicine.

Stress may help explain why patients with depression are at higher risk of cardiovascular disease

Patients with depression are at higher risk of cardiovascular disease, and a new study suggests that stress may help explain why.

Sitting harms blood vessel function, but cocoa flavanols can stop it

This study shows that cocoa flavanols can preserve endothelial function during sitting, suggesting dietary strategies to mitigate cardiovascular risks.

Multiple biological systems show abnormalities in ME/CFS patients

New Australian research has identified simultaneous abnormalities across multiple biological systems in people with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

AI enables rapid detection of coronary microvascular dysfunction from standard EKGs

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.

New data supports link between gum disease and heart disease

There is increasing evidence that gum disease is associated with increased risk of cardiovascular events, including heart attack, stroke, atrial fibrillation, heart failure and cardiometabolic health conditions. Effective prevention and treatment of gum disease, also called periodontal disease, could potentially decrease the burden of cardiovascular disease, according to a new scientific statement published today in the American Heart Association's flagship journal Circulation.

Study identifies molecular drivers of cerebral small vessel disease

A new study identifies molecular factors that promote small vessel disease - and an active drug that can restore impaired vascular functions.

Using sound waves to soften tumors and boost chemotherapy

Cancer is one of the leading causes of death in the U.S., second only to heart disease. But a new cancer treatment method from CU Boulder researchers uses sound waves to soften tumors and could be a potent tool against the disease.

Hypertrophic chondrocytes play a crucial role in bone growth and repair

Normal, regulated growth of skeletal bones is a crucial part of the growth of mammals. This is a complex process involving the growth of cartilaginous cells or chondrocytes, their transformation into bone-building cells or osteoblasts, and the formation of new blood vessels to supply the newly formed bone tissue.

Genetic differences in surfactant proteins influence retinopathy of prematurity risk

A new study from the University of Oklahoma suggests that small genetic differences in two proteins – previously known for their role in premature infants' lungs – may also influence how their eyes develop, potentially affecting the risk of retinopathy of prematurity (ROP).
