The cistern is a lumen or flat membranous space in the endoplasmic reticulum and the Golgi apparatus. A Golgi bundle can contain anywhere from three to twenty cisternae, but most contain six cisternae. The Golgi cistern can be divided into four sections: conjugated, medial, forked, and network of the Golgi cistern.

Drug Tolerance & Drug Synergy

بواسطة Wednesday، 23 February 2022، 12:06 AM - بيسان عبدالحميد مصطفى ولد علي _

Drug Tolerance:

Tolerance happens when a person becomes no longer responding to a drug in the way that he did at first. This can often lead to the person taking large amounts of the drug to achieve the same effect.

Drug Synergy:

An interaction that could be beneficial or harmful that occurs between two or more drugs that causes the total effect of the drugs to be greater than the sum of the individual effects of each drug.

Glycosylation

بواسطة Saturday، 5 March 2022، 10:27 AM - بيسان عبدالحميد مصطفى ولد علي _

Glycosylation:

is the attachment of carbohydrate side chains to proteins. Glycosylation is critical for a wide range of biological processes, including cell attachment to the extracellular matrix and protein–ligand interactions in the cell.

Types of Glycosylation:

N glycosylation or N-linked glycosylation: is the attachment of an oligosaccharide sugar molecule to a nitrogen atom in the asparagine residue of a protein molecule.

O glycosylation or O-linked glycosylation: is the attachment of an oligosaccharide sugar molecule to the oxygen atom of serine or threonine residues in a protein molecule.

N/O-linked Glycosylation
