Severe chronic pancreatitis is treated by removing the pancreas. Without a pancreas, patients also lose insulin-producing cells called islets. To preserve insulin responses, surgeons transplant islets to the liver, which has poor outcomes. New strategy uses a synthetic gel to transplant islets to the omentum, showing promise in small and large animal studies. With the new approach, more islets survived transplantation and grew blood vessels into the omentum.
Ancient apes in Germany co-existed by partitioning resources in their environment, according to a new study.
Paxlovid, effective in preventing severe COVID-19, didn't appear to help long-COVID patients in this single-center study. But further research may show benefits with different doses or for people with specific symptoms.
Giving a regular cash payment to the entire world population has the potential to increase global gross domestic product (GDP) by 130%, according to a new analysis. Researchers suggest that charging carbon emitters with an emission tax could help fund such basic income program while reducing environmental degradation.
By studying mutations in yeast and human cells, scientists say they have found that biochemical bonds between fats and proteins in the mitochondrion, the cell's powerhouse, play a crucial role in how our cells produce energy.
Feed costs for producing broiler chickens accounts for 60% to 70% of total production costs, and stump waste from the production of button mushrooms comprises nearly 30% of total mushroom weight. Marrying the two has the potential to reduce both cost and waste, especially in Pennsylvania, which is a national leader in the production of broiler chickens and button mushrooms.
Where there's smoke, there's not always fire. Wildfire smoke drifted to nearly every lake in North America for at least one day per year from 2019 to 2021, found a UC Davis study.
A team of researchers has developed a wirelessly activated device that mimics the wavelike muscular function in the esophagus and small intestine responsible for transporting food and viscous fluids for digestion.
A study has identified a biological mechanism that could lead to more effective treatments for breast cancer that has metastasized to the brain.
When we learn something new, our brain cells (neurons) communicate with each other through electrical and chemical signals. If the same group of neurons communicate together often, the connections between them get stronger. This process helps our brains learn and remember things and is known as long-term potentiation or LTP. Another type of LTP occurs when the brain is deprived of oxygen temporarily -- anoxia-induced long-term potentiationor aLTP. aLTP blocks the former process, thereby impairing learning and memory. Therefore, some scientists think that aLTP might be involved in memory problems seen in conditions like stroke.
Immunotherapy is one of the pillars in the fight against cancer and aims to enable the body's own immune system to fight a tumor. A recent study now shows that removing certain enzymes that regulate epigenetic processes from the so-called dentritic cells of the immune system influences their development and thus improves anti-tumor immunity. This finding could lead to new therapeutic strategies in immunotherapy.
By studying the brain anatomy of newborn baby baboons, a research group was able to predict what hand they would use to communicate after they had been weaned.
A research team has found a de-icing mixture with high effectiveness and low environmental impact after using machine learning to analyze ice melting mechanisms of aqueous solutions of 21 salts and 16 organic solvents.
Scientists have discovered an interesting new therapeutic target for the treatment of melanoma resistant to targeted therapies. Inhibition of the VARS enzyme could prevent this therapeutic resistance by resensitizing tumors resistant to these targeted therapies.
An international team of scientists has uncovered neural mechanisms used in planning. Its results suggest that an interplay between the brain's prefrontal cortex and hippocampus allows us to imagine future outcomes in order to guide our decisions.
Thousands of particles of light can merge into a type of 'super photon' under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers have now shown that this exotic quantum state obeys a fundamental theorem of physics. This finding now allows one to measure properties of photon Bose-Einstein condensates which are usually difficult to access.
A relatively simple peptide modification could unlock a whole class of targets for drug discovery, new research shows.
Researchers have created digital babies to better understand infants' health in their critical first 180 days of life. The team created 360 advanced computer models that simulate the unique metabolic processes of each baby.
One of the most confusing aspects for patients with type 2 diabetes mellitus is that they have high fasting glucose levels. This is because in these insulin-resistant patients, glucose production by the liver is triggered, a process that is still full of questions for the scientific community. Now, a review article presents a comprehensive overview of the most important advances in understanding this mechanism.
New camera chip design allows for optimizing each pixel's timing to maximize signal to noise ratio when tracking real-time visual indicator of neural voltage.
