Recognising the proteins that indicate cancer : News : News + Events : National Physica... - 0 views

  • All diseases have proteins, or concentrations of proteins, specifically linked to them called biomarkers, and identifying these can prove a powerful diagnostic tool. Antibodies can be used to test for specific biomarkers because they only bind to specific molecules or groups of molecules. Problems can arise when they bind to groups of similar molecules, leading to false positives and unreliable information.

Ovarian cancer Tests and diagnosis - Diseases and Conditions - Mayo Clinic - 0 views

  • Imaging tests, such as ultrasound or CT scans, of your abdomen and pelvis. These tests can help determine the size, shape and structure of your ovaries. Blood test, which can detect a protein (CA 125) found on the surface of ovarian cancer cells. Surgery to remove a tissue sample and abdominal fluid to confirm a diagnosis of ovarian cancer. Minimally invasive or robotic surgery may be an option. If cancer is discovered, the surgeon may immediately begin surgery to remove as much of the cancer as possible.
  • Stages of ovarian cancer include: Stage I. Cancer is found in one or both ovaries. Stage II. Cancer has spread to other parts of the pelvis. Stage III. Cancer has spread to the abdomen. Stage IV. Cancer is found outside the abdomen.

Can the Nervous System Be Hacked? - NYTimes.com - 0 views

  • But communication between nerves and the immune system was considered impossible, according to the scientific consensus in 1998.
  • It would have been “inconceivable,” he added, to propose that nerves were directly interacting with immune cells.
  • electrical pulses to the rat’s exposed vagus nerve. He stitched the cut closed and gave the rat a bacterial toxin known to promote the production of tumor necrosis factor, or T.N.F., a protein that triggers inflammation in animals, including humans.

      This small passage answer my question of 'if the nervous system could be directly wired to technology' 
  • the nervous system was like a computer terminal through which you could deliver commands to stop a problem,

      This is a refreshing approach to cures from medicine which has a tedious list of side affects with no promise of correcting the initial problem. 
  • Inflammatory afflictions like rheumatoid arthritis and Crohn’s disease are currently treated with drugs — painkillers, steroids and what are known as biologics, or genetically engineered proteins. But such medicines, Tracey pointed out, are often expensive, hard to administer, variable in their efficacy and sometimes accompanied by lethal side effects.
  • All the information is coming and going as electrical signals
  • His work seemed to indicate that electricity delivered to the vagus nerve in just the right intensity and at precise intervals could reproduce a drug’s therapeutic — in this case, anti-inflammatory — reaction. His subsequent research would also show that it could do so more effectively and with minimal health risks.
  • bioelectronics is straightforward: Get the nervous system to tell the body to heal itself.

    This post is incredible, it's exciting to understand how technology can tell the brain to heal itself.

Neuropsychopharmacology - Wikipedia, the free encyclopedia - 0 views

  • So far as we know, everything we perceive, feel, think, know, and do are a result of neurons firing and resetting. When a cell in the brain fires, small chemical and electrical swings called the action potential may affect the firing of as many as a thousand other neurons in a process called neurotransmission. In this way signals are generated and carried through networks of neurons, the bulk electrical effect of which can be measured directly on the scalp by an EEG device. By the last decade of the 20th century, the essential knowledge of all the central features of neurotransmission had been gained.[4] These features are:

      Electrical swings jump off the page for me because there is the connection between electricity and neurons. 
  • It has previously been known that ultimate control over the membrane voltage or potential of a nerve cell, and thus the firing of the cell, resides with the trans-membrane ion channels which control the membrane currents via the ions K+, Na+, and Ca++, and of lesser importance Mg++ and Cl-. The concentration differences between the inside and outside of the cell determine the membrane voltage.
  • Many receptors are found to be pentameric clusters of five trans-membrane proteins (not necessarily the same) or receptor subunits, each a chain of many amino acids. Transmitters typically bind at the junction between two of these proteins, on the parts that protrude from the cell membrane.

Jack Andraka: A promising test for pancreatic cancer ... from a teenager | Talk Video |... - 0 views

  • This kid went through over 4,000 proteins before finding mesothelin, a pancreatic, ovarian and lung cancer biomarker and developed a quick and cheap test for it's detection. Credit to Dr. Anirban Maitra, Professor of Pathology, Oncology, and Chemical and Biomolecular Engineering at Johns Hopkins School of Medicine, for recognizing the enthusiasm of this kid.
