A recent study found that nodal status is the strongest determinant of outcome after neoadjuvant therapy for esophageal cancer. Patients with complete pathological responses had better survival rates, but only if they also had no nodal involvement.
Researchers have developed a procedure using chitosan to create surgical materials with antimicrobial and healing properties, which remained unmodified after sterilization. Additionally, chitosan was found to be a natural bio-stimulant that boosts tomato seed germination and plant growth.
Mayo Clinic physicians have developed a new technique using real-time 3-D ultrasound to block nerve function in selected areas of the body prior to surgery. This allows patients to recover faster and with less need for pain medication. The technique has been successfully used in over 150 surgeries, showing improved outcomes for patients.
A phase III study of 341 high-risk patients with deep, local sarcomas shows significant improvement in tumour response and survival rates when treated with a combination of chemotherapy and local, deep hyperthermia. The combined therapy has been applied to patients before surgery, demonstrating its effectiveness.
A research team used Data Envelopment Analysis to evaluate the success of internet shops, finding that efficient websites like Jcrew and Abercrombie can serve as role models for less effective sites. By reducing inputs or increasing outputs, these non-efficient sites can improve their performance and competitiveness.
Researchers discovered clear changes in interstellar material absorption, indicating the existence of gaseous shells around a white dwarf. The system was likely composed of a white dwarf feeding on its red giant companion, leading to the supernova explosion. This finding strongly supports the Type Ia supernova scenario.
Surface plasmon polaritons move as waves and follow conventional optics' rules, limiting their size. Researchers developed a comprehensive theory to control SPPs, providing a bridge between nanoscale electronics and photonics.
A recent study published in the European Journal of Cardiovascular Nursing reveals that women who have suffered heart attacks experience higher rates of lingering depressive symptoms compared to their male counterparts. Women scored lower in physical and social functioning after one year, with 14.3% experiencing worsening depression.
A randomized clinical trial found that selenium supplementation increased the risk of developing type 2 diabetes by 55%, with higher levels associated with a greater risk. The study suggests that taking high doses of selenium may have detrimental effects in well-nourished populations.
During the International Polar Year, University of Alaska Fairbanks hosts summer institutes to train K-12 teachers on climate change. Seven UAF scientists provide hands-on lessons, translating scientific research into classroom useable content. The goal is to energize youth about science and promote Alaska's Grade Level Expectations.
Scientists at Karolinska Institutet have found a new way chromosomes are repaired after damage, contrary to the long-held view that cohesion only occurs during cell division. The discovery shows cohesin reactsivate when DNA breaks, allowing cells to fix damaged sister chromatids.
A study estimates nearly one-third of hospitalized US patients are vulnerable to VTE, which can lead to dire complications. Researchers stress the need for reinforcing national guidelines and monitoring compliance with hospital protocols for VTE prevention, as well as educating outpatients on preventive measures.
Researchers suggest that perennial water-ice deposits at Mars' South Pole are juggled between the North and South Poles every 51,000 years due to precession. Water vapour is transported from the North Pole to the South Pole, where it re-condenses and freezes, forming a thick layer.
Researchers at Hauptman-Woodward Institute have solved the structure of a novel protein in Pseudomonas, a bacterium that causes cystic fibrosis and tuberculosis. The discovery may lead to the development of new antibiotics to prevent infection in patients with CF and TB.
A 19-year study found that primate tourism practices can lead to adult aggression, disease transmission, and increased infant mortality. The study suggests that range restriction and provisioning for tourists contribute to the problem, making them an inappropriate management strategy.
Research suggests that anti-war activists are divided between supporting the Democratic Party and others, potentially complicating their electoral prospects. The study found that grassroots activists support the Democrats at a rate of around 40%, while non-Democratic activists work with organizations like United for Peace and Justice.
Researchers studying fantasy baseball aim to comprehend expert and novice players' approaches, as well as their learning processes. They analyze three leagues with varying levels of expertise, gathering insights into player strategies, community connections, and the role of technology in gaming.
Researchers developed a silk-based scaffold, SeriACL Graft, to regenerate or re-grow anterior cruciate ligament (ACL) tissue in goats. The study demonstrated the safety and efficacy of the device in promoting ACL regeneration, with 95% of animals returning to normal gait by 6 months.
