The study's findings suggest that chest x-rays may help clinicians better identify high-risk patients who require close monitoring.
Research suggests that microglia, immune cells in the brain, play a significant role in neuron loss during Alzheimer's disease. Stressed nerve cells secrete chemical messengers that attract microglia, leading to inflammation and elimination of neurons.
A new study published in Cancer suggests that infertile men are 2.6 times more likely to be diagnosed with high-grade prostate cancer than fertile men. The research found no association between the number of children a man has and his risk for prostate cancer, but rather focused on male fertility as a potential risk factor.
