Researchers at Virginia Tech discovered that Helicobacter pylori, a bacterium blamed for health issues like gastritis and gastric cancer, helps balance the stomach's ecosystem and control body weight and glucose tolerance in mice. The findings suggest that H. pylori may provide important metabolic traits required to combat diabetes.
Studies reveal that blocking TGF-β can prevent tumor recurrence in mice with triple negative breast cancer. Additionally, targeting specific subsets of immune cells, such as CD8+ regulatory T-cells, may provide a new approach to treating rheumatoid arthritis.
This study found that SUVmax is a significant and clinically independent marker for progression-free survival in stage I non-small cell lung cancer (NSCLC) patients. The research included 95 medically inoperable patients who received stereotactic body radiation therapy (SBRT), with median overall survival of 25.3 months and progression...
A recent NIH-funded study found that using advanced imaging shortly after an acute ischemic stroke did not identify a subgroup of patients who could benefit from clot removal procedures. The study, MR RESCUE, tested an invasive clot removal strategy in patients with large clots blocking major brain arteries.
Researchers at Pitt/UPMC successfully used brain-computer interface (BCI) technology to enable a paralyzed man to control a computer cursor and robot arm with his thoughts. The study, published in PLoS ONE, demonstrates the potential for BCI technology to help individuals regain independence after spinal cord injuries.
A team at Vienna University of Veterinary Medicine found the same strain of Usutu virus in dead blackbirds in Italy in 1996 as in Austria's cases. This suggests the virus was present in Italy before reaching Europe, and forensic pathology can help unravel origins of emerging diseases.
Research shows that babies of immigrant mothers in Ontario have higher birth weights compared to babies born in their mothers' native countries. The weight differences are more pronounced for babies born in poorer, less developed countries.
University of Notre Dame Sociologist Elizabeth McClintock's research offers new insights into physical attractiveness and age on mate selection. Her studies show that very physically attractive women are more likely to form exclusive relationships, while thinner women report fewer sexual partners.
The NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft is undergoing rigorous environmental testing at Lockheed Martin facilities. The tests simulate extreme temperatures, vacuum, and vibration to ensure the spacecraft can operate in space.
Research suggests that monitoring hepatic function with HIDA SPECT prior to and during radiation therapy can help tailor treatment plans for unresectable liver cancer patients. This assessment method allows for personalized radiation doses while minimizing the risk of liver injury.
A study exploring the impact of early parental death found that individuals experiencing bereavement as children are more likely to experience low self-esteem, loneliness, and isolation in adult life. Researchers recommend providing essential practical support and maintaining social networks to mitigate these effects.
Scientists studied evolutionary rates of nearly 20,000 human genes and found that genes involved in the same biological pathways change their rate of evolution in parallel. This signature can help identify partner genes that may work together in biochemical pathways, providing clues to their function.
A new study has found that bronchiectasis is independently associated with an increased mortality risk in patients with moderate-to-severe Chronic Obstructive Pulmonary Disease (COPD). The presence and severity of bronchiectasis were linked to a higher risk of death, independent of other known risk factors.
A subset of regulatory T cells has been identified that can remove pathogenic T cells, inhibiting disease progression in RA-like conditions. Small proteins have also been found to induce more of these beneficial T cells.
