LAB 1

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

 Robert G. Edwards was the first to develop In Vitro Fertilization (IVF) in the UK during 1978.

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

 Regulating the acrosome reaction. Harvey M. Florman, Melissa K. Jungnickel and Keith A. Sutton. International Journal of Developmental Biology. (2008) 52: 503-510
 This articles states that there are more complex pathways, besides just the Ca2+ signaling help to link sperm exocytosis and zona pellucida stimulation with each other. This article explains in, full detail, all the various in depth steps that are involved in the signal transduction pathway once a sperm makes contact with a zona pellucida.  

3.) Identify 2 congenital anomalies.

 1. Down Syndrome (trisomy 21)
 2. Tuerner's Syndrome (monosomy X)

LAB 2

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

Spermatazoa surface proteins bind to ZP3. After the sperm and egg membranes fuse and fertilization occurs IP3 pathways help to raise the level of intracellular Calcium, and an enzyme alters the ZP3 so that it will no longer bind any other sperm to the plasma membrane; this helps to prevent multiple fertilizations.

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)

Research article: Turner Syndrome http://www.nlm.nih.gov/medlineplus/turnersyndrome.html

Review article: Outcomes of spontaneous and assisted pregnancies in Turner syndrome: the U.S. National Institutes of Health experience http://www.sciencedirect.com.wwwproxy0.library.unsw.edu.au/science/article/pii/S0015028211005152

LAB 4

1. The allantois, identified in the placental cord, is continuous with what anatomical structure?

Bladder

2. Identify the 3 vascular shunts, and their location, in the embryonic circulation.

   * Ductus venosus - between the umbilical vein and IVC
   * Foramen ovale - between the right and left atrium
   * Ductus arteriosus - between the pulmonary artery and descending aorta 

3. Identify the Group project sub-section that you will be researching. (Add to project page and your individual assessment page)

LAB 5

1. Which side (L/R) is most common for diaphragmatic hernia and why?

Around 90-percent of diaphragmatic hernias occur on the left side, due to the fact that the left side closes later than the right side.
