Pediatric heart transplant method developed by U of A doctors allows for more surgeries, better outcomes: Study

A new pediatric heart transplant procedure has been shown to be at least as effective as the traditional approach, with similar survival rates and fewer infections. The method, pioneered by Canadian doctors, has enabled twice as many organs to be available for type O infants born with heart defects.

Inhibiting impact of dust aerosols on eastern Pacific tropical cyclones from the perspective of energy transmission

Dust aerosol optical depth negatively affects cloud water in the lower troposphere. This change can alter atmospheric enthalpy surrounding a tropical cyclone, influencing its intensity. Dr. Zhang's study suggests that anomalous enthalpy changes are related to dust AOD conditions in eastern Pacific TCs.

Text message program shows 60 percent of opioid tablets unused after common procedures

A new study by researchers at the University of Pennsylvania School of Medicine found that more than 60% of opioid tablets prescribed for patients undergoing orthopaedic or urologic procedures went unused. The study used an automated text messaging system to track patient pain and opioid use, revealing that most opioids are taken withi...

A T-cell stimulatory protein and interleukin-10 synergize to prevent gut inflammation

A study published in the Proceedings of the National Academy of Sciences has identified a synergy between ICOS ligand and interleukin-10 that promotes mutualism with the gut microbiota. The research found that mice deficient in ICOSL had increased frequencies of IL-10-producing CD4+ T cells, which were crucial for preventing severe inf...

Aerobic exercise may help address dialysis-related symptoms

Aerobic exercise has been shown to lessen several hemodialysis-related symptoms, including restless leg syndrome, symptoms of depression, muscle cramping, and fatigue. However, more research is needed to determine the extent of benefits from aerobic exercise for individuals with kidney failure who are undergoing dialysis.

New biomarkers of malignant melanoma identified

Scientists have identified new biomarkers in exosomes produced by cancer stem cells, which could help diagnose and predict malignant melanoma. These biomarkers were found to be present in the blood of patients with different stages of the disease, distinguishing them from healthy individuals.

Gene required for jumping identified in rabbits

A study published in PLOS Genetics identified the RORB gene as necessary for rabbits to perform their characteristic jumping gait. The researchers used a rare breed of domesticated rabbit with a developmental defect to pinpoint the cause, finding a specific mutation in the RORB gene that disrupts the animal's ability to jump.

A divided cell is a doubled cell

Researchers achieve complete control over vesicle division using osmosis and enzymatic reactions, producing single-phase 'daughter cells' with different membrane compositions. The team can also grow these cells back into phase-separated vesicles by fusing them with tiny vesicles.

When fly larvae are hungry

Researchers led by Dr. Katrin Vogt found that fly larvae adjust their behavior in response to internal states and context, similar to human brains. The study, funded by the German Research Foundation and NIH, sheds light on how the brain controls sensory processing.

Exposure to flame retardants early in pregnancy linked to premature birth

A new study has found a link between early exposure to flame retardants and an increased risk of premature birth in pregnant women. Women with high levels of polybrominated diphenyl ethers (PBDEs) in their blood were more likely to deliver their babies early, with no such association seen for those with lower exposure levels.
