Selective serotonin reuptake inhibitor

...s a more holistic approach (diet, exercise, sleep, stress reduction, etc). Furthermore, in late 2004 was much media attention given to a proposed link between SSRI use and juvenile suicide. For this reason, the use of SSRIs in pediatric cases of depression is now recognized by the FDA as warranting a caut...

Phage

...s of their host. When the host cell shows signs of stress (meaning it might be about to die soon), the endogenous phages become active again and start their reproductive cycle, resulting in the lysis of the host cell. An example is phage λ of E. coli . Sometimes, prophages even provide benefit to ...

When members of a species become separated, such as geographically, they face different environments, and tend to develop in different directions. After a long period of time, their traits will have developed along ...

Lambda phage

...te codes for proteins that look out for signs of stress in the host cell. Stress can be a result of starvation, poisons (like antibiotics), and other factors that can damage or destroy the host. At that point, the prophage becomes active again, excises itself from the DNA of the host cell and enters its ...

The abuse and forcible institutionalization of people with Down syndrome was closely linked to early twentieth-century racial and eugenic theory, culminating in t...

One can then apply clustering algorithms to that expression data to determine which genes are co-expressed. Further analysis could take a variety of directions: one 2004 study analyzed the promoter seque...

Examples of catabolic processes include breakdown of muscle protein in order to use amino acids as substrates for gluconeogenesis (much like burning furniture in your house as fuel because you are out of firewood), and breakdown o...

It has been hypothesized that this is a result of bone's piezoelectric properties, which cause bone to generate small electrical potentials under stress. Bones can be connected to mus...
