Selective serotonin reuptake inhibitors (SSRIs) are a class of antidepressants used in the treatment of depression, anxiety disorders, and some personality disorders. They are also typically effective and used in treating premature ejaculation problems. SSRIs increase the extracellular level of the neurotransmitter serotonin by inhibiting its reuptake into the presynaptic cell, increasing the l...

Archaeology is a destructive process in which accurate and detailed recording of a site is imperative. As a site is exposed, documentation is required in order to recreate and understand the site in context. We have developed a 3D modeling pipeline that can assist archaeologists in the documentation effort by building rich, geometrically and photometrically accurate 3D models of the site. The mode...

Mitochondrion structure. Data is obtained by using tomography. wikipedia Info: In cell biology, a mitochondrion (plural mitochondria) is a membrane-enclosed organelle found in most eukaryotic cells.[1] These organelles range from 0.5–10 micrometers (μm) in diameter. Mitochondria are sometimes described as "cellular power plants" because they generate most of the cell's supply of adenosine trip...

1. Motor proteins are a class of molecular motors that are able to move along the surface of a suitable substrate. They are powered by the hydrolysis of ATP and convert chemical energy into mechanical work. The most prominent example of a motor protein is the muscle protein myosin which "motors" the contraction of muscle fibers in animals. Motor proteins are the driving force behind most active tr...

An action potential is a spike of electrical discharge that travels along the membrane of a cell. Action potentials are an essential feature of animal life, rapidly carrying information within and between tissues. They also occur in some plants. Action potentials can be created by many types of cells, but are used most extensively by the nervous system for communication between neurons and for tra...

Nadia Rosenthal, Ph.D. www.hhmi.org Mature organisms have stem cells of various sorts, called adult stem cells. Adult stem cells supply cells that compensate for the loss of cells from normal cell death and turnover, such as the ever-dying cells of our skin, our blood, and the lining of our gut. They are also an essential source of cells for healing and regeneration in response to injury. Some a...
