The mucin genes
By: Alicia M Prater PhD
The genes encoding mucin proteins are generally designated MUC and have homologs in many species other than humans. Thanks to the Human Genome Project and the tireless work of genetic researchers, the National Library of Medicine and NCBI have a catalog of human genes, including...
What is a brain hemorrhage?
By: Alicia M Prater PhD
A brain hemorrhage is bleeding within the brain or brain cavity. The bleeding occurs when the relatively fragile blood vessels feeding the brain are damaged; they then leak blood, or hemorrhage, into the surrounding tissue and spaces. When the blood leaks directly into the brain...

Although viruses and bacteria are very different types of microbes, both have genomes made of nucleic acids. These nucleic acids contain the instructions necessary for cells and viruses to exist and reproduce. But since bacteria are living cells, the expression of their genes directs a...
How viruses and bacteria cause infection
By: Tami Port MS
Both bacteria and viruses can cause disease. However, these two types of infectious agents achieve their pathogenicity in different ways. Infection itself simply means that a pathogen has entered the body, but does not necessarily equate with disease, since a person can be infected by...
How subarachnoid hemorrhage is treated
By: Alicia M Prater PhD
