MicroRNA Quells Cocaine Craving
MicroRNA May Suppress Cocaine-Seeking Behavior
Currently there are very many people who are tripped in the use of drugs of abuse despite their life threatening effects. Drug addiction is a jail that many addicts find hard to evade. It is important to note that addicts do not use the drugs they abuse because they like using them, the honest truth however is that most addicts have tried to stop using their drugs of choice but they can’t just fight against their own craving. The cravings for drugs like cocaine that are known for their euphoric effects are one of the challenges that addicts face.
Typically, a person will use the drug once as an escapade to all the stress that he may be exposed to or as a result of mere curiosity having been misled by their peers that using cocaine is cool as they say it. However after getting the euphoric effects one is bound to go for more of this drug and this in the long run may result to cocaine addiction and even dependence. It has never been easy quitting the use of cocaine and many people even after going to rehab centers will still for the drug when exposed to triggers after they come back from the rehabs. It is this cocaine seeking behavior that is adopted by the addicts that makes it hard for them to quit. If this cocaine seeking behavior can be reduced then a person may win the fight against cocaine addiction easily.
The recent discovery by scientists that a minute snippet of genetic material called microRNA may suppress cocaine-seeking behavior presents hope to the medical fraternity as well as cocaine addicts. As a known fact the use of cocaine will cause both structural and functional alterations to the brains’ reward system. These changes cause a drift in the behavior of the users of cocaine. Through experiments and lab tests it has been found that these alterations results in increased drug-seeking behavior in both humans and rats. The desire to use cocaine become uncontainable hence overindulgence in drug use.
Just like with any other drugs of leisure, long-term use of cocaine will result in reduced response to the effects of cocaine which will force the user to use more of cocaine so as to achieve the sought euphoric feeling. After a long time of use of this drug the response will be lessened again and this will reduce the motivation of a user to continue using the drug. Researchers suspect that these differing influences may be why only about 15% of cocaine users ultimately lose control and compulsively seek the drug.
MicroRNAs are small pieces of RNA that don’t code for proteins but they regulate how much of a protein is made instead. Over the past decade, microRNAs have been linked to various cancers, degenerative disorders and other conditions. It was until recently that the contribution of these tiny molecules to drug use and addiction were brought under scrutiny.
Paul J. Kenny led study
In a research team that was led by Dr. Paul J. Kenny of the Scripps Research Institute in Jupiter, Florida, the team decided to explore how brain levels of specific microRNAs change when rats have extended or limited access to cocaine. The study was funded by NIH‘s National Institute on Drug Abuse (NIDA).
In the issue of Nature published on July 8, 2010, the scientists reported that rats given 6 hours of extended access to cocaine each day had markedly increased levels of a molecule called microRNA-212 in a particular brain region. The levels were nearly double those in rats with access to cocaine for an hour or less daily. The brain region, called the dorsal striatum, helps to regulate the development of habit formation.
After this discovery the researchers next tested the effects of elevated microRNA-212. The Researchers used a genetically altered virus to boost microRNA-212 expression in the dorsal striatum. A control group received an “empty” virus. When given extended access to cocaine, both groups predictably escalated their intake. But over time, cocaine intake plummeted in the rats with elevated microRNA-212. Cocaine consumption in this group continued to drop even as their exposure to the drug increased. Their cocaine intake became so low that they seemed to have a growing dislike for the drug.
To contrast the effects of this microRNA-212 in the brain, the researchers blocked the action of microRNA-212 in the brain and this led to sharp increase in cocaine intake and the rats began to self-administer the drug at exaggerated rates, similar to compulsive drug users. These results suggest that microRNA-212 may play an important role in preventing out-of-control drug use.
“The results of this study offer promise for the development of a totally new class of anti-addiction medications,” says Kenny. “Because we are beginning to map out how this specific microRNA works, we may be able to develop new compounds to manipulate the levels of microRNA-212 therapeutically with exquisite specificity, opening the possibility of new treatments for drug addiction.”
the fact that Cocaine consumption in the group of rate with elevated microRNA-212 continued to drop even as their exposure to the drug increased is a clear indication that that this minute component of genetic material may be used to quell the craving for cocaine in cocaine users.

Testosterone is a very important hormone in the body. Of all the androgens it is the most dominant and is charged with very many responsibilities. Many people still think that testosterone has only one function which is to ensure a good sexual performance. No testosterone has far more functions that together make your life what it ought to be. So, to the many people who think that deficiency in testosterone hormone can only affect your sexual life, it’s time to think again. The reality is that this hormone has very many roles beyond ensuring a healthy sex life. Apart from production of sperms, the testosterone hormone is also crucial in production of red blood cells. This hormone also helps in distribution of fats in the body parts, increasing muscle mass, improving bone mineral density and even regulation of moods in a person. A major symptom of those suffering flooring testosterone levels is low moods. It is common to find men who are suffering from hypogonadism in bad moods as any decline in this hormone does much to dampen moods of an individual. It is also this hormone that gives men the physique of man- masculinity.
Testosterone replacement therapy has been used for a long time in treatment of men with erectile problems which are also a major cause of anxiety among men. Hypogonadism is a problem that most men go through and seek treatment from every day. however many patients seem to concentrate on getting their sexual energy back but are blind to other conditions that might be suffered as a result of hypogonadism. Men who suffer hypogonadism are not strangers to anxiety and depression and therefore emphasis should be placed more on the debilitating effects of low testosterone levels other than a fall in sexual drive and performance in men as is mostly the case. The use of testosterone replacement therapy in hypogonadism is not news, however some people are still not aware of the link between anxiety and depression and low testosterone levels.





A recent research has found out that more teens use e-cigarettes than traditional,
“Part of the reason for the popularity of e-cigarettes is the perception among teens that they do not harm health,” Miech said.

The healthy stem cells are capable of changing the chemical composition of our brains and how the brain works. When healthy stem cells are transplanted into the damaged brain area. In the case of drugs; the area of the brain that controls impulses and chemical reactions to substances they begin to rebuild that area without the previous cellular dysfunction. This means that 





New medical advances have made it possible to offer treatments for various
Stem cell transplant is a new intervention in the medical field. It works by replacing the damaged stem cells with healthy ones. The ability of the stem cells to multiply rapidly and give rise to millions of other healthy cells is an interesting phenomenon that the medical experts are taking full advantage of in treating diseases that have caused suffering to humans. In treating ADHD having the damaged stem cells replaced by healthy ones through stem cell transplant, the implanted stem cells with capability of giving rise to many other stem cells with higher degrees of differentiation helps in treating this disease.
