A Different Kind of Exercise Boost: Irisin Injections and Liver Health

January 2, 2025

Exercise is great for the body, especially the liver. It cuts down on stress that oxidizes (takes away oxygen from) cells. Scientists think a protein called irisin might be behind this benefit. In a study, mice got irisin injections or did endurance exercises for 8 weeks. Researchers looked at how t

The Hidden Side of DNA Damage: How 8-oxoGua and OGG1 Impact Cancer

January 2, 2025

When your body's cells produce energy, they also create byproducts called reactive oxygen species (ROS). These can damage DNA in various ways, one of the most common being the oxidation of guanine, a building block of DNA. This oxidized form is known as 8-oxoguanine (8-oxoGua). If not fixed, 8-oxoGu

The Power of Left Atrial Strain: A Game Changer in Cardiovascular Disease?

December 29, 2024

Left atrial strain (LAS) is a relatively new way to gauge how well the left atrium, a crucial part of the heart, is working. Changes in LAS can hint at the development of cardiovascular diseases early on. This makes LAS a promising tool for spotting these diseases at an early stage, which could lead
