New research has revealed that red blood cells function as critical immune sensors by binding cell-free DNA, called nucleic acid, present in the body’s circulation during sepsis and COVID-19, and that this DNA-binding capability triggers their removal from circulation, driving inflammation and anemia during severe illness and playing a muchContinuar Leyendo

A clinical trial has found that treatment with the immunomodulator interferon beta-1a plus the antiviral remdesivir was not superior to treatment with remdesivir alone in hospitalized adults with COVID-19 pneumonia.

Colorectal cancer is projected to claim 53,000 lives in the United States this year alone and, as with most cancers, the disease is deadliest when it metastasizes. It follows that the most effective way to control it would be a drug that targets metastasis itself — preventing cancer cells fromContinuar Leyendo

In the earliest days of the COVID-19 pandemic, the medical community turned to a century-old treatment: Take blood from recovered patients and give it to the sick. The hypothesis was that components in the so-called «convalescent plasma» that fought off the disease once could do it again, something that hasContinuar Leyendo

Most strokes happen when an artery in the brain becomes blocked. Blood flow to the neural tissue stops, and those tissues typically die. Because of the locations of the major arteries in the brain, many strokes affect motor function. Some affect vision, however, causing patients to lose their vision orContinuar Leyendo

Opioids are a class of substances that control sensations such as pain and emotions in animals. While plant-derived opioid narcotics such as morphine are the most well-recognized, other opioid molecules like endorphins can also be synthesized by the body or artificially developed in laboratories. Opioids exert their actions by bindingContinuar Leyendo
