| Study shows how bioactive substance inhibits important receptor Posted: 25 Mar 2022 09:27 AM PDT The A2A receptor regulates how vigorously the innate immune system attacks diseased cells. Researchers have now been able to show for the first time how an important inhibitor binds to the receptor. In the future, the results will facilitate the targeted search for molecules that give the innate immune system more punch. These could for instance be used in the fight against cancer, but also against brain diseases such as Alzheimer's or Parkinson's disease. |
| Half of all women experience false positive mammograms after 10 years of annual screening Posted: 25 Mar 2022 09:27 AM PDT Half of all women experience a false positive mammogram after 10 years of annual breast cancer screening with 3D mammography, a UC Davis-led study estimates. This risk was lower for women who had mammograms every other year. 3D screening showed slightly lower false positive results than standard mammography. |
| Large study challenges the theory that light alcohol consumption benefits heart health Posted: 25 Mar 2022 09:27 AM PDT In an observational analysis of UK Biobank participants, light to moderate drinkers had the lowest heart disease risk, followed by people who abstained from drinking; however, light to moderate drinkers tended to have healthier lifestyles than abstainers, which likely accounted for their better heart health. Genetic evidence in this same population suggested that all levels of alcohol intake are associated with increased cardiovascular risk. Notably, the risk of cardiovascular disease linked to light alcohol consumption was modest but rose exponentially with higher intake, even at intake levels currently endorsed as 'low risk.' |
| Study finds neurons that encode the outcomes of actions Posted: 25 Mar 2022 09:27 AM PDT A group of neurons in the brain's striatum encodes information about the potential outcomes of different decisions. These cells become particularly active when a behavior leads a different outcome than what was expected, which the researchers believe helps the brain adapt to changing circumstances. |

| Spinal fluid sampling used to track treatment response in pediatric glioma Posted: 24 Mar 2022 03:47 PM PDT Treatment for glioma has long relied on MRI imaging to track tumor markers and treatment response. But new findings suggest a new method could provide additional data about tumor markers before changes appear on an MRI, indicating possible strategies to help clinicians address this aggressive form of cancer. |
| Cells dancing harmonic duets could enable personalized cancer therapies Posted: 24 Mar 2022 03:46 PM PDT Mechanical engineers are using two electronic 'voices' singing a harmonic duet to control suspended particles and cells in new and valuable ways. Their prototype device can form and rotate a single-layer crystal from a group of particles, create arbitrary shapes with a given number of particles, and move pairs of biological cells together and apart again hundreds of times. These abilities could serve fields like materials science, biophysics, life science and medicine. |
| New research shows certain exercises can help with muscular dystrophy Posted: 24 Mar 2022 03:46 PM PDT A new study using neuromuscular electrical stimulation (NMES) in zebrafish found that certain activities may help strengthen muscles affected by Duchenne muscular dystrophy, a severe type of muscular dystrophy that affects young boys. The researchers designed four NMES regimens for zebrafish with a mutation that closely modeled the disease. They then put the fish into an underwater 3D printed 'gym' made up of tunnels and electrodes, and analyzed their skeletal muscles to see how they had changed. |
| Novel method to identify and treat aggressive early-stage lung cancers Posted: 24 Mar 2022 12:41 PM PDT Researchers have developed a novel method to identify aggressive early-stage lung cancers and target drugs known as aurora kinase inhibitors to tumors that are especially likely to respond to them. The findings could lead to great advances in treatment for lung adenocarcinoma, the most common type of lung cancer. |
| Distant regions of the human brain are wired together by surprisingly few connections Posted: 24 Mar 2022 12:41 PM PDT Understanding how the brain functions, particularly how information is processed during different activities, is difficult without knowing how many axons are in the brain and how many connect different functional regions. A new study shows that despite the functional importance of connections between far-reaching regions of the brain, the actual number of these connections is low. |
| One in four women experience domestic violence before age 50, analysis finds Posted: 24 Mar 2022 11:38 AM PDT Over one in four women (or 27 per cent) experience intimate partner violence before the age of 50, according to a worldwide analysis. The largest of its kind, the analysis covers 366 studies involving more than 2 million women in 161 countries. |

| Tuberculosis infection protects mice from developing COVID-19 Posted: 24 Mar 2022 11:37 AM PDT In mice, the immune response mounted against tuberculosis prevents them from developing COVID-19, according to a new study. |
| Mechanism that underlies local dopamine release in the brain Posted: 24 Mar 2022 11:37 AM PDT When we initiate an action in our everyday lives—chasing after a runaway napkin or getting out of the car—the brain releases a chemical messenger called dopamine that helps regulate the brain area that controls this action. |
| Tuberculosis induces premature cellular aging Posted: 24 Mar 2022 10:03 AM PDT Researchers found that the cells of humans and animals who have recovered from tuberculosis had prematurely aged up to 12 to 14 years. It's possible that this premature cellular aging is one reason why survivors of tuberculosis have a high risk of mortality. |
| Health risk due to micro- and nanoplastics in food Posted: 24 Mar 2022 10:02 AM PDT Five grams of plastic particles on average enter the human gastrointestinal tract per person per week. This is roughly equivalent to the weight of a credit card. Whether ingested micro- and nanoplastics pose a health risk is being investigated in numerous studies but is largely unknown to date. A research team has now summarized the current state of scientific knowledge. |
