"Ziehl-neelsen" Meaning
The Ziehl-Neelsen stain is a staining technique used in bacteriology to identify acid-fast bacteria, such as Mycobacterium tuberculosis (the causative agent of tuberculosis), and some species of non-pathogenic bacteria and fungi.
Developed in 1896 by Abram Ziehl and Friedrich Neelsen, this technique involves applying a special stain to a specimen to determine if the bacteria possess the cell wall component mycolic acid, which makes them resistant to decolorization when exposed to an acid-alcohol solution, a characteristic property of acid-fast bacteria.
The Ziehl-Neelsen stain is typically performed as part of a routine diagnostic test to detect and isolate pathogenic bacteria in a specimen, and it remains a widely used technique in medical microbiology to this day.

Zidovudine
Zidovudine, also known as AZT (AZT), is a medication used to prevent and treat HIV/AIDS. It is an antiretroviral drug that belongs to a class of medications called reverse transcriptase inhibitors. Zidovudine works by blocking the reverse transcriptase enzyme, which is essential for the replication of HIV (human immunodeficiency virus). By inhibiting this enzyme, zidovudine prevents the virus from replicating and reduces the amount of virus in the body. This helps to slow down the progression of HIV to AIDS and also prevents the transmission of HIV from mother to child during pregnancy and childbirth.

The stepped design allowed for the ziggurats to be visible from great distances, signifying the power and prestige of the ruling dynasty or city-state.
