Medical professionals use transverse brain images for diagnosing various neurological conditions. The axial plane is the basis for the transverse view. Ever wondered what’s really going on inside your head? No, I’m not talking … Read more

A polygon exhibits regularity when all its sides achieve equality, defining it as equilateral, and when all its angles are equal, thus being equiangular: a square exemplifies this with its four congruent sides and right angles. The attributes of both equilateral and equiangular polygons intertwine within geometric theorems, particularly influencing shapes like regular hexagons, whose … Read more

Immune Tolerance Induction represents a pivotal mechanism in the realm of immunology. It modulates the immune system. The immune system is a complex network. This network distinguishes self from non-self. Immune tolerance induction aims to establish a state of unresponsiveness. It targets specific antigens. Autoimmune diseases are conditions. These conditions arise from a failure of … Read more
