Personalized medicine in psychiatry: problems and promises

Personalized medicine in psychiatry: problems and promises | healthcare technology | Scoop.it

The central theme of personalized medicine is the premise that an individual’s unique physiologic characteristics play a significant role in both disease vulnerability and in response to specific therapies.


The major goals of personalized medicine are therefore to predict an individual’s susceptibility to developing an illness, achieve accurate diagnosis, and optimize the most efficient and favorable response to treatment. The goal of achieving personalized medicine in psychiatry is a laudable one, because its attainment should be associated with a marked reduction in morbidity and mortality.


In this review, we summarize an illustrative selection of studies that are laying the foundation towards personalizing medicine in major depressive disorder, bipolar disorder, and schizophrenia. In addition, we present emerging applications that are likely to advance personalized medicine in psychiatry, with an emphasis on novel biomarkers and neuroimaging.


Excerpt From the Conclusion:


The prospect of personalized medicine in psychiatry more or less reflects ideals still largely unrealized. Currently, the field is at the information-gathering infancy stage.


The greatest progress can be expected at the intersections of the categories described above, such as gene × environment and genes × biomarkers, which will poise psychiatry to make biological system-based evaluations. Furthermore, some of the emerging applications, including imaging genomics, strengthen our conviction that the future for personalized medicine is highly promising.

DNA Nanotechnology the Future of Modern Medicine?

DNA Nanotechnology the Future of Modern Medicine? | healthcare technology | Scoop.it

One of the most significant achievements in the field of biomedical engineering is the creation of DNA nanobots. These molecular robots made of DNA are designed to deliver medicines to specific cells that require healing and to target harmful cells, killing them without harming the healthy ones.


Unlike commonly used drugs and supplements, nanobots have a measure of intelligence and can conveniently move through the body in smart ways.


How are these nanobots produced? Scientists use DNA, breaking up the components and rearranging them into shapes such as barrels to carry medicine. DNA naturally has a tendency to react in certain ways to outside stimuli, and its components assemble according to natural attraction and repulsion. These reactions are manipulated to make the nanobots and to program them.


Nanobots are free-floating structures that move through the bloodstream and remain neutral until they encounter a particular site that requires assistance. With the help of molecular cues programmed into them, they can identify a precise location and perform the necessary actions.


Treatment with nanobots could prove to be especially effective against cancer. With chemotherapy treatment, healthy cells are killed along with the cancerous cells. Nanobots can detect the cancerous cells, however, and only release medicine upon encountering them.

This article is about the eventual use of nanotechnology in humans to work as little nurses, called nanobots, to deliver medicine directly to sick or cancerous cells with out harming the healthy cells. I am really fascinated by nanotechnology, it is crazy ad unknown to me, i would really like to learn more about it. This article is from The Epoch Times, which in their "about us" claims "unwavering commitment to objective reporting" .

So long as the little bugs damage my insides!
