Abstract:

RenbÖk phenomenon is the withdrawal of one clinical lesion when another lesion appears. This is a case report of an 11-year-old girl with multiple hyperpigmented scaly plaques over the scalp, trunk, and bilateral upper and lower limbs. The patient also had patchy hair loss over the scalp, which was spared from the scaly plaques. The case report thus elaborates on a fascinating immunological mechanism between the two autoimmune diseases that spares the patient from one disorder should the other appear.

Position-effect Variegation

Position-effect Variegation

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

Social Proof

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Cohesion

Cohesion

Cohesion is the attraction between molecules of the same type, such as water molecules. Water molecules have an overall neutral charge but are polar molecule. An oxygen atom in one water molecule has a partial negative charge that can bind to a hydrogen atom with a partial positive charge in a second water molecule, forming a hydrogen bond. Each water molecule can form up to four hydrogen bonds with other water molecules. Hydrogen bonds are responsible for water's cohesive nature.
