A mathematical model predicts and explains the emergence of burst suppression, a low-activity state in response to reduced cellular energy. The study suggests that burst suppression may be used to guide induced coma and track recovery from brain injuries, offering new insights into brain neurochemistry and neurophysiology.
A new study examines how numerate individuals process information differently, leading to more informed decisions. People who are numerate are less influenced by other information and see numbers as abstract symbols, allowing them to make better choices.
Scientists at the University of Alberta have shed light on the structure and function of PNKP, a key DNA repair enzyme. By understanding how this enzyme repairs damaged DNA, researchers hope to develop new therapies that target cancer cells while leaving healthy cells intact.
Researchers at Thomas Jefferson University found that intraarticular delivery of local analgesic bupivacaine reduces postoperative pain and narcotic consumption, while minimizing complications. The study suggests a potential new option for better pain management following knee replacement surgery.
Researchers discovered that osteoarthritic knee joints have a constant state of repair, while hip joints do not. This suggests different treatment strategies may be needed for knee and hip osteoarthritis. A biomarker was identified to measure joint degeneration and repair response.
A new study found that weight gain and dietary changes are not effective in preventing repeat preterm birth. Women who have had a prior preterm birth should follow standard weight gain guidelines during their second pregnancy to minimize risk.
Researchers report successful early transplantation of human placenta-derived mesenchymal stem cells into neonatal rats with birth-related brain damage, detecting neurologic improvement.
A study published in Cell reveals that only a handful of genes and proteins guide the growth of motor neurons, which eventually connect with muscles. This discovery may lead to new therapies for ALS and provide insight into certain cancers.
Researchers analyzed metal-on-metal hip replacement studies for negative outcomes, finding no bias in results from authors with disclosed conflicts. Despite a trend towards increasingly negative study results over time, the findings support the AAOS's disclosure requirements and peer review process.
Researchers at Northwestern University have developed a new method for creating scaffolds that are more flexible and less time-intensive than current technology. The process uses ceramic nanoparticles and elastic polymers to create highly interconnected pores that do not require the use of salt.
Manan Mehta developed a method to create circularly permuted proteins, which are useful for studying molecular evolution and designing biosensors. The new technique uses transposase engineering to create diverse protein variants with great control.
A Yale University study found that C-section deliveries before 34 weeks of pregnancy for small-for-gestational-age babies are associated with higher odds of developing respiratory distress syndrome. The researchers analyzed data from 2,885 preterm babies and found a significant link between C-sections and breathing problems.
Researchers at the University of Cambridge have discovered that iron pyrite, commonly known as 'Fool's Gold', has catalytic properties. The study focused on the reactions between iron pyrite and nitrogen oxides, an extremely poisonous class of compounds produced by car engines and industrial power plants.
Researchers analyzed tumor specimens from 19 advanced stage carcinoma patients, discovering changes in biomarker expression that may impact therapy selection for women with recurrent ovarian cancer. The study highlights the importance of analyzing current tumor tissue to make informed treatment decisions.
