Video of blood clot contraction reveals how platelets naturally form unobtrusive clots

A Penn study reveals the physical mechanism of how platelets contract and shrink blood clots, which can inform new ways to diagnose and treat conditions like ischemic stroke and deep vein thrombosis. The research found that contracting platelets cause clots to shrink by bending and shortening individual fibrin fibers.

Uncomfortable sight from an ancient reflex of the eye

A new study from Penn researchers shows that a reflexive system of the human eye also produces a conscious, visual experience that may be related to excessive light sensitivity. The findings suggest that people have brain activity and a visual experience in response to invisible light pulses that stimulate melanopsin cells.

Mutation in fallopian tube lesions may help catch ovarian cancer years earlier

Researchers discovered that tumor cells in the fallopian tubes of women at high-risk for ovarian cancer can be detected years before they develop into the disease, providing a potential window of time for early detection and intervention. The study identified TP53 gene mutations as an early indicator of ovarian cancer development.

Are teens more likely to take charge of their health when money is on the line?

Researchers at the University of Pennsylvania School of Medicine conducted a randomized control trial showing that providing small financial incentives can motivate young people to engage in daily glucose monitoring. Participants who received $60 monthly credits were nearly three times more likely to achieve daily goals, but overall gl...

Proton therapy lowers treatment side effects in pediatric head and neck cancer patients

A study published in Pediatric Blood and Cancer found proton therapy to be as effective as photon radiation while improving quality of life for pediatric head and neck cancer patients. The treatment resulted in similar rates of tumor control and lower rates of toxicity, with no severe side effects reported.

Penn researchers receive $6.4m in NIH funding to create center to transform mental health services

Researchers at Penn will launch the ALACRITY Center with three projects to enhance treatment for people served through publicly-funded mental health systems. The center aims to identify effective ways to encourage patients to take antidepressant medication and improve use of evidence-based practices among one-to-one aides assigned to w...

Deciphering biological meaning from an atlas of gene expression across 42 tissue types

A new study published in Nature and Nature Genetics describes a comprehensive atlas of gene expression across 42 tissue types, providing insights into the molecular origins of human disease. The study's findings allow researchers to identify genetic factors that cause changes in gene expression and relate them to human disease risk.

Black children less likely to see doctor for eczema despite being more severely affected

A new study from the University of Pennsylvania found that black children with eczema are 30% less likely to see a doctor for treatment compared to white children. Despite having more severe disease, minority children experience lower healthcare utilization rates due to various barriers.

Sleep deprivation is an effective anti-depressant for nearly half of depressed patients

A meta-analysis found that sleep deprivation, administered in controlled settings, rapidly reduces symptoms of depression in approximately half of patients. The study suggests that partial sleep deprivation is equally effective as total sleep deprivation and medication does not significantly influence the results.

Blocking sweet taste receptors can help body fight off sinus infections

Researchers at the University of Pennsylvania School of Medicine have identified amino acids that activate sweet taste receptors, which can block the release of antimicrobial peptides and kill bacteria. This new understanding could lead to new treatments for chronic sinus infections, affecting nearly 35 million Americans annually.

Better understanding of 'one of the most complex organs' for better lung treatments

A study published by researchers from the University of Pennsylvania School of Medicine has identified two distinct cell types in the lungs, one promoting regeneration and the other forming scar tissue. This discovery could lead to targeted therapies for conditions such as idiopathic pulmonary fibrosis and chronic obstructive pulmonary...

Liver cancer patients can start with lower dose of chemotherapy and live just as long

Patients with hepatocellular carcinoma can start with a lower dose of sorafenib without affecting overall survival, experiencing fewer side effects and lower treatment costs. The reduced dose approach allows patients to ramp up as they show tolerance, while the standard dose may require ramping down due to toxicities.

Art courses could help medical students become better clinical observers

Researchers found that art observation training significantly improved observational recognition skills among first-year medical students. The study also showed improvements in empathy and emotional recognition, as well as an increase in open-mindedness. Art training alone can help teach medical students to become better clinical obser...
