Type your answers on a separate document and submit through Moodle.
Lab Assignment Part One: Analysis of scientific paper
To complete this assignment, read the following paper, available on Moodle:
‘Effect of 25-OH-vitamin D on fracture healing in elderly rats’ published in the Journal of Orthopaedic Research in 1998. The first author listed on the paper is A.D. Delgado-Martínez.
Note: There are some format differences in this article compared to what you learned in lecture. The article refers to the abstract as the ‘summary’. Also, the Introduction section is not labeled, but it is the first paragraph following the summary.
For questions 1 – 7, answer the question and
state the first section of the paper other than the abstract
(i.e. Introduction, Materials and Methods, Results, or Discussion)
where you found the information. (5 points each)
1.
What is the question the researchers are attempting to answer in this experiment?
2.
How did the researchers measure how much the rats’ fractures had healed?
3.
What is the foundation/context for this study? In other words, where does this study fit into the larger picture, or what is the basis for the study?
4.
How did the mechanical strength of the rats’ bones relate to the levels of 25-OH-vitamin D in their blood?
5.
What statistical test was used to analyze the data?
6.
Which of the four biomechanical parameters measured were found to be different between the control and treatment groups? Which were not significantly different?
7.
What were the sample sizes for the control and treatment groups?
Answer Questions 8 & 9 using complete sentences (5 points each)
8.
The authors mention a specific previous study (by Einhorn et. al.) about vitamin D and rat fracture healing. What were the findings of this previous study? How did these previous findings compare to those of the current study?
9.
A previous study
found that 25-OH-vitamin D actually impaired
fracture healing in rabbits. Does this mean that one of the studies must be invalid? Why or why not?
Lab Assignment Part Two: Find & summarize a primary and secondary source

Name the three basic classes of drug targets in medicinal chemistry and indicate, which are the most/least important as targets for biologics?
I don't sure if I answer these questions correctly. Hope someone can give me confirmation and explain to me how enzymes will be affected by bioloigcs?
My answer so far:
The three common classes of drug targets are; receptors, nucleic acid, and enzymes. As a target for biologics, the least important will be a nucleic acid, and the most important will be receptor and second enzymes.
Biologic drugs such as monoclonal antibodies will bind to the antigens, which are overexpressed receptor that need to be deactivated. In this case, the monoclonal antibodies will act as an antagonist and block the ligand from binding to the antigens, which are extensively presented in cancer cells. In addition, it can also affect enzymes by.......?

Question 2
Which of the following is/are true with regard to the therapeutic index and the therapeutic window
of a drug (there may be more than one true statement)?
Therapeutic index is defined as ED50/TD50.
Drugs with a narrow therapeutic window are best suited for minor conditions like headache or muscle
pain.
Therapeutic window is the dose range that maximizes efficacy at minimum toxicity.
Drugs with a wide therapeutic window can be used to treat serious life-threatening diseases.
All of the above are correct.
