Following the fecundation of an egg by a sperm, the fertilized egg begins a series of cell divisions that leads to the formation of a mass of cells known as the blastula. This mass contains two types of cell masses, the trophoblast, and the inner cell mass. The trophoblast leads to the formation of the…
Nanomedicine is an area of medical applications that focus on the use of nanotechnology for the diagnostic of diseases, delivery of drugs, and repair of damaged tissues in patients. The materials that are used by this technology are named nanomaterials due to their size which is within the nanometer range. What Is a Nanomaterial? Nanomaterials…
Cancer is a group of diseases characterized by an uncontrolled division of cells known as proliferation that may lead to invasion and destruction of local and surrounding tissues and organs. This invasion step may be followed by the passage of the invasive cancer cells into the circulatory system and their spreading to other organs of…
Epigenetics is a natural and regular process by which environmental and behavioral factors affect the expression and activity of genes, independently of alterations in DNA sequences (genotype), such as during genetic mutations. These modifications can be transmitted to daughter cells and are influenced by several factors, including age, the environment, lifestyles, and disease states. These factors…
Gene therapy is a field of biology or medicine that focuses on introducing or replacing defective genes that are involved in the etiology of some genetic diseases. To introduce or replace defective genes, this approach involves using viral or non-viral vectors to insert healthy copies of genes into the cells of affected people to re-establish their normal…
