Controlling Motor Symptoms of Advanced Parkinson's

This resent research is important because it brings forth new and significant light into the treatment for those who suffer from Parkinson's disease. Parkinson's affects around 1 million people in the U.S. Doctors diagnose up to 60,000 new cases each year. Those with Parkinson's disease suffer from dyskinesias. It is one of the most common symptoms to occur to those who have it. Dyskinesias means, abnormality or impairment of voluntary movement. Neuroscientists assume dyskinesias come from fluctuations in dopamine. The drug that is usually used to restore dopamine levels is levodopa. The problem with levodopa is that sometimes dopamine levels become too high, and results are unstable and treatment for dyskinesias is unsafe. A team of researchers tested two drugs on whether the drug LY235959 (an NMDA receptor antagonist) or NBQX (an AMPA receptor antagonist) could calm hyperactivity and dyskinesia symptoms in Parkinson's model monkeys. Both drugs lowered the SPN firing frequency of levodopa by 50 percent. The results show dopamine levels stabilize and abnormal movements are merely diminished. The drugs aren't yet safe for human consumption but this new research adds more light and more insight for helping those with Parkinson's disease. With more and more research happening daily on this disease we hope that those that suffer can one day live a life with the ability to control the symptoms of dyskinesias.

    I wonder how the two drugs LY235959 (an NMDA receptor antagonist) or NBQX (an AMPA receptor antagonist) effect the individuals tested on a molecular level? Possibly by knowing how the drugs work we can see why they are unsafe for humans and hopefully change them in a way to where it is possible to use them to treat humans.

Kill The Pain But Not The Patient

               Opioid’s are a serious problem that according to Edward Bilsky, an opioid pharmacologist and provost at Pacific Northwest University of Health Sciences, can potentially be eliminated. Opioid addiction is a problem that needs to be faced as soon as possible. Utah has many different ads that are sure to be seen driving on the freeway, but we are not the only state that has an issue. Many people have died and many more will continue to die “In 2015, 2 million Americans suffered from prescription opioid addiction, and more than 33,000 died of an opioid overdose” (pg. 44) There is a solution to the problem at hand.               In Jonathon Keats’ article, building a better Painkiller, Christopher Stein stumbled upon something that would change the way that opioids are researched. He noticed that among rats an inflamed leg would be numb to the effects of touch, but anot...

Cell phones and Cancer?

Some recent studies are calling us to be more cautious about our cell phone usage. There have been some studies on lab rats over the last two years that have started linking cell phone usage to higher cancer rates. Basically what the experiment was, Scientists exposed a bunch of lab rats to about the same amount of RF radiation (Radio Frequency, the kind of radiation cell phones use to communicate with cell towers) cell phones and wireless routers and basically all of our modern internet devices, expose us to. Long story short the Rats had a noticeably higher rate of schwannomas, and cancer in glial cells than regular non-exposed rats.  There were some other really cool findings from the study too. For example only Male lab rats contracted Schwannomas (cancer of Schwann cells in nerve tissue) and only female lab rats were found to have glioma. (cancer in glial cells, cells that help brain cells) They also found higher levels of other types of cancer such as skin cancer, prostat...

Stem Cell Research and its Importance

Over the last few years there has been lots of research done regarding stem cell research, to regenerate and fix damaged organs in the body. With the help of stem cell research there has been much discovered about the body in general which helps to advance the cause of medicine helping to finding cures and treatments for different diseases and disorders. To show some of the research I am writing this blog post on, “Targeted Repair of Heart Injury by Stem Cells Fused with Platelet Nanovesicles.”             I have chosen this paper because it illustrates different discoveries scientist have had while finding a way to potentially help stem cells to regenerate cardiac tissue following a myocardial infarction or a heart attack. Through the course of this paper, Junnan Tang and the other scientists he was working with talked about one of the hardest issues regarding cardiac stem cells which is the fact that they have a hard time impla...
