Hace 11 horas · Declining estrogen (E2) leads to physical inactivity and adipose tissue (AT) dysfunction. Mechanisms are not fully understood, but E2’s effects on dopamine (DA) activity in the nucleus accumbens (NAc) brain region may mediate changes in mood and voluntary physical activity (PA). Our prior work revealed that loss of E2 robustly affected NAc DA-related gene expression, and the pattern ...

The mitochondria, and thus mitochondrial DNA, are passed exclusively from mother to offspring through the egg cell. Illustration of the location of mitochondrial DNA in human cells Electron microscopy reveals mitochondrial DNA in ...
Hace 11 horas · Radians, a versatile unit of angle measurement, play a crucial role in describing rotations. In a full revolution, the arc length of a circle’s circumference equals the circle’s radius multiplied by 2π radians. This relationship allows for precise measurements of angular quantities, enabling calculations of arc lengths, angular velocities, and accelerations. Radians find widespread ...
