Lizzy leads STAT’s FDA coverage. Her story explores the relationship between politics and science at the FDA, its influence on industry, and the agency’s ability to protect and promote public health. Sensitive information can be sent on Signal at lizzylaw.53.A Food and Drug Administration advisory committee is scheduled to meet Thursday and Friday to discuss changes to make peptides more accessible as more Americans experiment with synthetic peptides despite warnings about unproven benefits and potential risks. At issue is whether compounding pharmacies will be allowed to manufacture seven types of peptides that are currently designated as unsafe to manufacture. The…

NASA is preparing for a future astronaut landing on the moon with a major orbital rehearsal planned for 2027. During the Artemis III demonstration mission, space crews and teams on Earth will practice rendezvous and docking operations between the Orion spacecraft and a commercially developed lunar lander. Information collected during Artemis III, along with data from future unmanned demonstrations near the moon, will help NASA improve astronaut safety and reduce risk ahead of manned moon landings starting in 2028. Two civilian landing craft join Artemis III NASA has partnered with SpaceX and Blue Origin to develop a human landing system…

A newly developed dental gel has the potential to rebuild damaged tooth enamel, potentially creating a new approach to preventing cavities and repairing worn teeth. Scientists from the University of Nottingham’s School of Pharmacy and School of Chemical and Environmental Engineering have created a material that mimics the biological processes that naturally form enamel. Their findings were; nature communicationssuggests that the gel may help repair enamel weakened by mineral loss and erosion, strengthen enamel that is still healthy, and protect teeth from future damage. Gel that recreates natural enamel growth Dentists can quickly apply the gel using a process similar…

An ancient molecule that existed long before the evolution of blood circulation systems has been found to support cancer immunotherapy. Researchers at Nagoya University in Japan found that the complement C3 protein acts within tumors to prevent the accumulation of immunosuppressive cells, but only when produced within the tumor. C3 circulating in the blood did not affect treatment results. Published in nature communicationsthe findings suggest that replicating this effect artificially could help patients with tumors that don’t naturally produce enough of this protein. The C3 protein is evolutionarily very old and is present in simple organisms such as sponges and…

Spermidine has attracted scientific interest in everything from cell recycling to cognitive aging, but the evidence needed for routine human use has not yet emerged. Research: Gerontological insights into the natural metabolite spermidine in aging and age-related diseases. Image credit: Corona Borealis Studio / Shutterstock In a recent “Article in Press” review published in the journal npj agingResearchers considered mechanistic, preclinical, and clinical evidence to evaluate spermidine’s anti-aging properties. Spermidine is a ubiquitous natural polyamine and a calorie restriction mimic that is essential for cell proliferation and tissue homeostasis. The review results highlighted that while spermidine may partially restore autophagic…

Thymus-derived peptides reduced inflammatory immune activity and improved immunotherapy responses in aged mice, suggesting a potential strategy to address age-related barriers to cancer treatment. Research: Thymulin suppresses age-related myeloid inflammation and enhances cancer immunotherapy. Image credit: Lightspring Recent research published in journals nature communications Our results suggest that the thymus-derived peptide thymulin may suppress age-related bone marrow cell inflammation and enhance the response to anti-programmed death ligand 1 (anti-PD-L1) immunotherapy in older mice bearing mammary tumors. The researchers found that pro-inflammatory myeloid cells were significantly enriched in the mammary tumor microenvironment of older mice, with a higher proportion of myeloid…

Despite the widespread availability of analgesics, pain management remains one of the most important and widespread challenges in modern medicine, with more than 20% of the world’s population suffering from chronic pain, especially chronic neuropathic pain characterized by central sensitization. However, current standard treatments continue to rely heavily on opioids and NSAIDs, which are limited by insufficient efficacy, gastrointestinal toxicity, and serious risks of dependence and addiction, creating a need for novel, effective, and non-addictive brain-penetrating analgesics. Insilico Medicine (“Insilico”, HKEX:3696), a clinical-stage generative AI-driven drug discovery company, is addressing this critical unmet need by using AI to uncover new…

A natural compound called ovalactone (OL) may offer a new treatment for rheumatoid arthritis (RA), according to research published in 2017. engineering. OL is a tetracyclic triterpenoid isolated from yellow leafy cortex. Researchers found that it reduces signs of arthritis by promoting the degradation of acyl-coenzyme A thioesterase 1 (ACOT1) through the ubiquitin-proteasome pathway and restoring the balance of unsaturated fatty acids. This finding helps explain how OL acts at the molecular level against rheumatoid arthritis. They also identify ACOT1 as a potential new drug target and suggest that correcting disrupted fatty acid metabolism may be a useful strategy for…

Antibiotics are a wonder of medicine, but many microorganisms have acquired the ability to resist and tolerate these treatments. Scientists at St. Jude Children’s Research Hospital have revealed how it works. pneumococcus Adapts to antibiotic exposure and immune pressure. Their findings revealed that changes in RNA regulation allow bacteria to enter a state of antibiotic resistance. The results provide a deeper understanding of how pathogens tolerate treatment and may inform strategies to improve the effectiveness of existing antibiotics. The survey results are announced today. Cell hosts and microorganisms. Bacterial infections remain a significant clinical challenge for children with cancer and…

An analysis of more than 42,000 deaths in the United States related to multiple sclerosis (MS) found that mortality rates varied by age, region, race, and ethnicity, with black patients dying younger than white patients and high blood pressure contributing to the increase. Research results just published in the journal Neurologypoints out the need for timely diagnosis and better prevention strategies to extend the lifespan of MS patients. MS is a chronic disease that damages the brain and spinal cord, causing symptoms such as vision problems, muscle weakness, and fatigue. People with MS have a shorter life expectancy than the…
