DOPAMINE - THE HAPPY HORMONES!!!!!!!!

-
Hi Folks!! Follow our blog on Instagram
Dopamine is a neurotransmitter, a brain chemical that transmits messages between neurons (brain and nerve cells). Dopamine is one of the better-known brain chemicals. A so-called “happy” neurotransmitter, dopamine plays an important role in mood regulation, movement, and how humans experience pleasure and pain.Dopamine plays a key role in several medical conditions like Parkinson’s disease, fibromyalgia, and restless leg syndrome. Mental health conditions like ADHD, addiction, depression, schizophrenia, and OCD are also linked to dopamine disorders.


Low dopamine activity can have different physical, cognitive (thinking), and emotional effects. The symptoms of the different conditions vary, depending on the region of the brain where dopamine activity is lacking.Symptoms of inadequate dopamine activity include:
  • Rigid muscles that feel stiff and achy
  • Tremors
  • Muscle cramps or spasms
  • Diminished balance and coordination etc

High levels of dopamine and excessive dopamine activity in the brain can be debilitating.High dopamine activity is linked to:

  • Anxiety
  • Excess energy or mania
  • Increased feelings of stress
  • Insomnia
  • Aggression
  • Hallucinations

Diseases associated with low levels of dopamine:

  • Attention deficit hyperactivity disorder (ADHD).
  • Parkinson’s disease.
  • Restless legs syndrome.

Diseases associated with high levels of dopamine:

  • Mania.
  • Obesity.
  • Addiction.

Diseases associated with both high and low levels of dopamine:

  • Schizophrenia. 
Role of dopamine in addition:                                                                                                           

When a person develops an addiction to a substance, it’s because the brain has started to change. This happens because addictive substances trigger an outsized response when they reach the brain. Instead of a simple, pleasurable surge of dopamine, many drugs of abuse—such as opioids, cocaine, or nicotine—cause dopamine to flood the reward pathway, 10 times more than a natural reward.The brain remembers this surge and associates it with the addictive substance. However, with chronic use of the substance, over time the brain’s circuits adapt and become less sensitive to dopamine. Achieving that pleasurable sensation becomes increasingly important, but at the same time, you build tolerance and need more and more of that substance to generate the level of high you crave.


Academic Doping:                                                                                                                       
Dopamine's impact on learning has led some high school and college students to take dopamine-boosting medications in the hopes of doing better on tests. This practice has not been proven to work, and it is not recommended by healthcare providers because of the many potentially dangerous side effects.

Hi Folks!! Follow our blog on  Instagram China’s patent and trademark office has upheld a key patent within the portfolio of CRISPR/Cas9 intellectual property belonging to Nobel Laureate Emmanuelle Charpentier, The Regents of the University of California, and University of Vienna (known collectively as CVC), and licensed for commercial use through ERS Genomics. Dublin-based ERS Genomics said the China National Intellectual Property Administration (CNIPA) has upheld Patent No. CN201380038920.6, “Methods and Compositions for RNA-guided Target DNA Modification and for RNA-guided Transcription Regulation”. ToolGen claims that it was the  world’s first  filer of patents covering gene editing in eukaryotic cells using the CRISPR-Cas9 system. “The decision by the CNIPA fully upholding the patent further demonstrates its validity and value as part of the patent collection for use of the CRISPR/Cas9 technology,” ERS Genomics stated in announcing the Chinese decision recently. The CVC patents ha

Hi Folks!! Follow our blog on Instagram  LAB IN THE BOX XPOSAT - STUDY ABOUT BLACKHOLE (A GIST) Last year was a huge success with Chandrayaan-3. Our ISRO Scientist did a lot of unexpected acts and surprised us all. On January 1st, when this year started, India has proved to be a leading country in the world, not only on land, but also in the sky.  There are a lot of things in our universe that we don't understand. One thing that we don't understand is black holes. These black holes exist in a lot of places in space. From the fact that we are in a black hole, to the fact that all the earth and sun will disappear one day in a black hole, this is something that we don't understand. From the biggest scientist to the modern technology scientist, everyone is looking at this black hole as a mystery. To study this, India has launched a special Mission on January 1st named XPoSat( X-ray Polarimeter Satellite). On January 1st, India launched 10 different satellites throug

History of Biotechnology

HISTORY OF BIOTECHNOLOGY: People have been harnessing biological processes to improve their quality of life for some 10,000 years, beginning with the first agricultural communities. Approximately 6,000 years ago, humans began to tap the biological processes of microorganisms in order to make bread, alcoholic beverages, and cheese and to preserve dairy products. But such processes are not what is meant today by biotechnology, a term first widely applied to the molecular and cellular technologies that began to emerge in the 1960s and ’70s. A fledgling “biotech” industry began to coalesce in the mid- to late 1970s, led by Genentech, a pharmaceutical company established in 1976 by Robert A. Swanson and Herbert W. Boyer to commercialize the recombinant DNA technology pioneered by Boyer, Paul Berg, and Stanley N. Cohen. Early companies such as Genentech, Amgen, Biogen, Cetus, and Genex began by manufacturing genetically engineered substances primarily for medical and environmental uses. For
