A hairy death
Apoptosis or programmed cell death is an essential part of life. For example, it’s critical to human development. Where would we be if every fetal cell survived? Some cells must die to form, say, our fingers and toes; others must perish to shape our functional brains.
Cells frequently commit suicide for the good of the whole. They may become apoptotic in response to viruses or gene mutations in order to prevent further damage. Menstruation relies upon programmed cell death.
Apoptosis may be necessary, but it’s not necessarily pretty. Above is a scanning electron micrograph of several cultured HeLa cancer cells. The cell at the center is undergoing apoptosis. During the process, the cell’s cytoskeleton breaks up, causing the outer membrane to bulge and decouple. The resulting wart-like structures are called blebs, which eventually break off and are consumed by phagocytic cells for recycling.
Ok guys, this is a video of a man getting beaten in the streets of Venezuela for running away and the camera man getting shot at the end on 2/13/14. This is real and this is happening now. There’s nothing we can really do except spread the word. These are the kinds of things happening in Venezuela right now. Spread the word and pray for the people. — [video] [other post]
An Arteriovenous Malformation (AVM) is a congenital malformation of the vascular system in which arteries and veins are directly connected, bypassing capillaries. The result is a giant tangle of arteries and veins, and in space restricted areas like the brain you can imagine the negative affect one these can have on a person. The first-line treatment for an AVM is surgical embolization; they go in through the vascular system and cut the blood supply to the malformation off. The AVM then dies and stops putting pressure on the surrounding tissues. If the AVM is superficial in the brain they can perform a craniotomy and slowly shrink and remove the AVM.
