Purpose

The purpose of this assignment is to collaboratively create a shared annotated bibliography to help guide our research for the next part of the HIV project where we will investigate the structure and function of mutations in the gp120 protein.

  • How many cited references does that article have? 88
  • How many articles have cited the article you have been assigned? 50

14. What are the relative merits of searching with Google Scholar, PubMed, and Web of Science? Name two advantages and disadvantages for each.

  • Google Scholar (Advantages): Provides citations in a variety of styles, as well as the number of times an article has been cited. Google scholar gives the most search result with the most flexibility with keywords.
  • Google Scholar (Disadvantages): Did not have the option for me to only search for peer reviewed articles, also it does not rank search results on the number of times the keywords searched appear in the article.

PubMed (advantages): Pubmed provides access to other databases offered by the NLM (National Library of Medicine). PubMed allows the largest number of keywords per search and filters out non peer-reviewed articles. Pubmed (disadvantages): Pubmed focuses on medical and biomedical sciences but has limited information on other sciences. Pubmed is the only database of the three that does not provide citation analysis. Web of Science (advantages):Web of Science covers the oldest publications, because its indexed and archived records go back to 1900. Easily access the number of times an article was cites as well as track citation history. Web of Science (disadvantages): Updated less frequently than the others (around once a week). Search engine is not as intuitive as pubmed and not even close to google scholar.

15. What impact does choice of keywords have on your results?

  • The number of keywords inputted give more accurate results and filters based on title first, then number of times keywords are found within the article.
  • The conjunction 'and' when put between words brings search results including both those words.

16. Now we will begin to evaluate your assigned article in three areas availability, the journal, and the article metadata. Again, provide a citation for the article in APA format, this time including the DOI. For the following questions, for information that is not available, answer n/a).

17. Evaluating the source--the journal

  • Journal of Virology
  • For profit
  • In collaboration with the American Society of Virology
  • not a member of the Open Access Publishers Association
  • USA
  • Since February of 1967
  • Yes they are peer reviewed
  • https://jvi.asm.org/content/board-editors
  • 4.324 (2018)

18. Evaluating the source--the article

  • Primary research article
  • Received 13 October 2005
  • Accepted 8 December 2005
  • March 2006, did go through some revision but not to any data/figures
  • about 4 months
  • Vanderbilt University Chair/Professor of Immunology, Microbiology, Pathology
  • Current projects of the Aiken lab include:

HIV-1 capsid structure and function (Cell 139:780-90, 2009; Nature 497:643-6, 2013). Role of host cell proteins in HIV-1 infection (J. Virol. 82:12001-8, 2008; J. Virol. 87:422-32, 2013). Mechanism of HIV-1 restriction by TRIM5alpha (PLos Pathog. 4(5):e1000074, 2008; J. Virol. 84:6564-69, 2010; PLos Path 7:e1002009, 2011; J. Virol. 87:9271-8, 2013). Identification and mechanisms of HIV-1 capsid inhibitors (J. Virol. 85:542-9, 2011). Conformational Masking of HIV-1 Env proteins during virion maturation (PLoS Pathog 7:e1002234, 2011).

  • Initial interactions between HIV-1 particles and target cells occur between gp120 and CD4. CD4 binding elicits a conformational change within gp120 that reveals a binding site for the viral coreceptor. Subsequent engagement of coreceptor initiates further conformational changes in gp41 that lead to membrane fusion.
  • I believe that this article would be good for a journal club because it pertains to prior topics discussed, but it may be a bit too long since this journal does not have a limit on the page count.

Conclusion

By doing this assignment, I learned quite a bit about the way in which biologists conduct research. I always knew that there were different sources but I never cared to inquire about the credibility of the journal or the article, including the authors and publishers. This also gave me some key insight for when I personally do research. Now, I will know whether I want to use Google Scholar, PubMed, or the Web of Science and by assessing the pros and cons of each, our class has an edge over other young researchers who would probably just guess with where to start, much like I used to. Therefore, I believe that it is important to assess and evaluate the journal and article as well as the authors and publishers before we begin to read in article because that establishes credibility and trust with the work.
