virulent phages kill the cell to release their progeny (although filamentous phages are able to export progeny without cell lysis). Temperate phages may exert an effect similar to virulent phages, but they may also integrate in the
Neurons are the cells that process and transmit information in the brain. Each cell has two connectors, the axon and dendrite. The axon of one neuron connects with the dendrite of another at a junction or synapse. Special chemicals called neurotransmitters help transfer the electrical impulse acros...

Many traits that have been shown to be involved in bacterial cooperation and virulence are coded by mobile elements, such as traits that are capable of breaking down toxins in the local environment (Knothe et al., 1983; Philppon et al., 2002; Lee et al., 2006; Ellis et al., 2007) ...
Caused when ablood clot(typically from a deep vein in the leg) breaks off and goes into the pulmonary arteries of the lungs. This causes shortness of breath and low oxygen levels because the pulmonary arteries deliver blood into the lungs to distribute oxygen throughout the body, which cannot...
Free radicals are produced when the body breaks down foods for use or storage. But they are also produced when we expose to tobacco smoke, radiation, and air pollution. These unstable molecules make their way through our bodies, scavenging cells to try to snatch missing pieces—electrons. They...
If facilities lack adequate safety protocols, there is a constant risk of exposure to hazardous substances to workers as well as nearby communities. For example, the burning of wiring and cables increases the concentration of dioxins — toxins known to increase the risk of cancer if inhaled by ...
"Breakouts in the forehead region [are] said to represent digestive imbalances, like poor diet, improper digestion, or irritable bowel syndrome." To help flush out toxins and aid digestion, swap caffeinated and overly processed drinks with some H2O. If you have bangs or naturally oily hair, ...
