Inhibitor Improves Learning Essay Example for Free

Inhibitor Improves Learning EssayThe name is entitled, Peripheral Delivery of a ROCK Inhibitor Improves Learning and Working Memory. Title of the journal the article was published in and date published This article was published in the journal entitled Behavioral Neuro acquirement in February 2009. The journal is published by the American Psychological Association. Describe the topic and the experiment conducted. What did they do? The article noned that in related studies, the RhoA/ROCK/Rac pathway is involved in the cognitive processes. Thus, they postulated that if this pathway could be inhibited, accomplishment and memory can be enhanced. The article explained that fasudil has been used in experiments for the treatment of vasospasm and angina but not for learning and memory. Hydroxyfasudil is an active metabolite of fasudil. The necessitate subjects were 27 rats who were 17 months old and 18 months old at the time of actual mienal testing. Specifically, the plain used F ischer-344 male rats who were bred at the aging resolution of the National Institute on Aging at Harlan Laboratories (Indianapolis, IN). All the rats were acclimatized before the actual experiment according to IACUC standards and all the procedure done were with the approval of the topical anaesthetic IACUC committee.NIH standards were followed. The study was done in Arizona State University. The study convocationed the rats into three experimental groups. The first group of rats received saline and was labeled as the aged vehicle group. The second group received 0. 1875 mg hydroxyfasudil and was labeled as the aged low battery-acid group. The third group received 0. 3750 mg hydroxyfasudil and was labeled as the aged high dose group. Of the 27 rats, nine belonged to the aged vehicle group, another nine rats in the aged low dose group, and another nine rats in the aged high dose group.Since hydroxyfasudil has a half- feel of around 5-7 hours in humans, the drugs were all administe red in the morning before behavior testing was done. All injections were given by subcutaneous injection at the scruff of the neck of the rat. All experimenters who performed the behavioral testing and succeeding dissections of the rats brains were blind to the various(prenominal) treatment groups of the rats. The behavioral testing used the Water Radial Arm inner ear to test working and reference memory, and the Spatial Reference Memory Morris Maze to test for spatial learning and memory.The performance of the rats in these two mazes were compared and used as basis as to whether cognitive functions were enhanced or not with the governance of hydroxyfasudil. Summarize the most important results. What did they find and what does that mean? 4 pts The results of the behavioral testing done using the water radial-arm maze, the aged high dose group was superior in all measures evaluated learning advocate scores for total errors, working memory correct errors, and working memory incor rect errors. Better learning was indicated by having a high learning index. Aged high dose group showed better learning on all three measures. The groups learning index when compared to the aged vehicle group was significantly higher. As for the aged low dose group, it still had a higher learning index when compared to the aged vehicle group but only marginally for the working memory incorrect errors. For the other two measures, the group still had a higher learning index but no longer marginally, but intermediate between the aged high dose and aged vehicle groups suggesting that the relationship may be dose-dependent.Another important result noted was that hydroxyfasudil did not significantly alter spatial reference memory performance in either maze. 5) What implications do these results have for future research? What should they look at next? The implications of study would mean that if hydroxyfasudil can inhibit events that influence cognition, the next step would be to assure this in result in a larger number of mice or even in rabbits. They should also look into the side effects of hydroxyfasudil and a total start would be to look for the same side effects found in its parent compound which is also being currently studied. ) Does this study propound anything that could be useful to society (the general population, not science), and if so, what is it? This study showed that if hydroxyfasudil does improve cognitive function by improving spatial learning and memory, then science has found another possible answer to age-related or neurodegenerative-related memory dysfunction.To put it simply, hydroxyfasudil, if safe and effective in improving spatial learning and memory, will avail patients who suffer from age-related or neurodegenerative-related memory dysfunction. ) What are some possible confounds or errors that this study should have controlled for, but did not? Essentially, what would make this a better study? In my opinion, this study was a good o ne with very negligible confounders. One thing that might have made the study better though was the possible side effects of hydroxyfasudil on the short term and also long term. 8) What did you learn that you did not know before? What did you find most fire?I found that fact that such a drug as hydroxyfasudil being a possible treatment for those suffering from age-related memory dysfunction, fascinating. I did not know this until I read this article. If it is indeed a possible cure, many people all over the world would live a better life in their advanced age since their memory will serve them better and they will depend less on their children and thus, have a less probable chance of being placed in homes just because families have difficulty caring for them.
