--Mark Hill 09:38, 3 August 2011 (EST) All 3 questions from Lab 1 need to be completed before Lab 2.

Lab 1 Assessment

1. Identify the origin of In Vitro Fertilization and the 2010 nobel prize winner associated with this technique.

In Vitro Fertilization refers to the fertilization of an egg cell outside of the organism, usually in a laboratory environment. Robert G. Edwards was the first to successfully perform this process in 1978, and was awarded the Nobel Prize in Physiology or Medicine in 2010 as recognition for his work in developing this method of fertilization.

2. Identify a recent paper on fertilisation and describe its key findings.

Groeneveld, E.; Broeze, K. A.; Lambers, M. J.; Haapsamo, M.; Dirckx, K.; Schoot, B. C.; Salle, B.; Duvan, C. I. et al. (2011). "Is aspirin effective in women undergoing in vitro fertilization (IVF)? Results from an individual patient data meta-analysis (IPD MA)". Human Reproduction Update 17 (4): 501–509.

The key finding of this paper is that aspirin is not effective in women undergoing IVF. Women who take aspirin after IVF did not show improved pregnancy rates after IVF.

3. Identify 2 congenital anomalies.

- Congenital Diaphragmatic Hernia - Spina Bifida

Lab 2 Assessment

1. Identify the ZP protein that spermatozoa binds and how is this changed (altered) after fertilization.

Spermatozoa bind to Zona Pellucida Glycoprotein 3 (ZP3). After fertilization has occured, enzymes digest the zona pellucida and spermatozoa are no longer able to bind to ZP3 as it is altered by these digestive enzymes.

2. Identify a review and a research article related to your group topic. (Paste on both group discussion page with signature and on your own page)

The primary journal article I found talks about the expression of the DMD Gene Products in Embryonic Stem Cells, so I'm hoping that this will allow our group to elaborate a bit on the genetic aspects of the development and potential early identification, as symptoms do not usually appear in humans until a few years of age [1]. Also the review article I found refers to two other types of muscular dystrophies as well as DMD (SCARMD, CMD), highlighting many key developments in research. Seem to be very informative, also refers a bit to the importance of animal models in these developments [2].

Lab 3 Assessment

1.What is the maternal dietary requirement for late neural development?

NHRMC Policy (1993) suggests that an intake of 0.4-0.5mg of folate is required to reduce incidence of neural tube defects and allow for normal neural development. --Z3288196 12:35, 11 August 2011 (EST)
