Murburn concept explains why oxygen is acutely needed to sustain life

Murburn concept (from “mured burning”, signifying a restricted uncontrolled oxidative process) provides a tangible rationale why oxygen is so quintessential for immediate maintenance of life-order. It postulates that oxygen-centered diffusible reactive species (DRS, like superoxide radical) are

Our biological clock controls mitochondrial activity in a tissue-dependent manner

The molecular circadian clock and tissue-specific clocks

Mitochondria are the cell organelles that are responsible for the largest part of cellular energy production. Within these organelles both the tricarboxylic acid cycle (TCA cycle) and oxidative phosphorylation (OXPHOS) are taking place. In these cycles ATP,

link between aerobic respiration and anaerobic respiration

Until recently, it has been conventional thinking that mammals cannot live without oxygen. This has been challenged by studies demonstrating survival of mole rats without oxygen for extended periods of time. The ability of mammalian cells to

Oxygen affects buds burst in grapevine

Grapevine is the most economically important fruit crop worldwide and is the mainstay of rural communities in over 100 countries. However, grapevine production is concentrated in latitudes of 30°-50°, and largely in maritime regions, due to its
