Researchers at Osaka Metropolitan University found compounds in nucleic acids from salmon DNA and torula yeast RNA inhibit cancer cell growth. These compounds may prevent cancer by stopping cell replication.
Researchers at Linköping University develop a new method to deliver strong compounds specifically to bacteria, allowing for efficient and safe treatment of infections. The TOUCAN strategy uses nucleases to target bacterial DNA, reducing side effects associated with current antibiotics.
Researchers found that after 96 weeks, some patients achieved loss of detectable HBsAg and reduced liver inflammation levels, indicating functional cure. The study suggests that discontinuing long-term antiviral therapy may be more effective than continuing it for certain patients.
A study published in Journal of Hepatology found that some patients with chronic hepatitis B can achieve sustained immune control by discontinuing antiviral therapy after four years. This suggests a potential cure for the disease, which affects an estimated 350 million people worldwide.
Researchers discovered that leukemia cells immediately unresponsive to treatment have high levels of SAMHD1, while those with acquired resistance use the enzyme DCK to activate nucleoside analogues. This finding may lead to better cancer therapies.
