Finally, I found the layout of the table under the heading ‘Legal status’ to be very well put together. There are however some countries placed under the incorrect continents and I found that the order was easily changed and mixed up. I also noticed that several of the countries were linked to the same sources which made the information very unspecific. Instead of just links I think a few sentences explaining the legislation would be more informative. | Finally, I found the layout of the table under the heading ‘Legal status’ to be very well put together.

Relationship of polar bodies morphology to embryo quality
This study was conducted in hopes to find a method to forecast the quality of embryo derived from reproductive technology. 355 patients that were undergoing In-Vitro Fertilisation or Intracytoplasmic Sperm Injection (ICSI) were a part of this study. From these patients 3048 zygotes were extracted and placed into two groups; intact or fragmented.
The oocyte was extracted 37 to 28 hours after recombinant human chorionic gonadotropin administration followed immediately by the collection of semen sample. The semen sample was then treated and prepared for fertilisation of the oocyte. The zygotes were recruited after 16 to 18 hours and their polar bodies examined and placed into their respective groups based on morphology. The development of the zygotes were then closely studied and graded against systems such as the Istanbul consensus and Gardner's grading system.
At the conclusion of the study it was deduced that the zygotes with intact polar bodies performed remarkably better than those with fragmented polar bodies. During the third day the intact polar body group had better embryo rates, blastocyst rates and available embryo rates. The pregnancy rate and implantation rate of the two groups however were found to have no differences.
Microdroplet In Vitro Fertilization Can Reduce the Number of Spermatozoa Necessary for Fertilizing Oocytes
During In vitro fertilisation (IVF) usually a large sample of spermatozoa is needed. In the female body only a few spermatozoa reach the oocyte. This study introduces the idea of micro droplet IVF in hopes of mimicking the in vivo conditions and lowering the amount of spermatozoa needed. Mice were used as the subjects for all the experiments performed and the procedures were conducted using HTF fertilisation medium.
This study involved several counterparts where each experiment tackled different factors that may affect the microdroplet IVF procedure. The microdroplets conprised of only one microlitre containing either 5, 10, 20 or 50 spermatozoa in comparison to the usual 80 - 500 microlitres. Each of the experiments were replicated four times using spermatozoa from different males and either cyropreserved or fresh samples. The first experiment tested the effects that the cumulus cells, GSH and sperm number, the second on varying numbers of oocytes and spermatozoa, third on the effect of using cyropreserved sperm, the fourth on the effects of using volumes of suspension larger than the optimal for the preparation of the cyropreserved sperm and the fifth was to ensure normal development of embryo.
The study was deemed successful where as little as 5 spermatozoa could fertilise an oocyte. The rate of success was also found to be heightened depending on factors, for example the presence of cumulus cells was found to be beneficial to the spermatozoa fertilisation rate. Microdroplet IVF could be the alternative pathway for those who have depleted numbers of spermatozoa due to factors such as age, genetic conditions or damages to sperm over time.
--Mark Hill (talk) 17:02, 3 September 2015 (AEST) These are reasonable summaries of these 2 papers. If you intend to use acronyms, they should be spelt out in full the first time they appear with the acronym then in brackets. (5/5)

ANAT2341 Student 2015 Quiz Questions
--Mark Hill (talk) 17:15, 3 September 2015 (AEST) You left off the closing quiz code, I have added it above. Q1 is not technically correct as the mid piece provides the energy for motility, not actual motility. You need to also explain in your revealed answer why the other options are incorrect. Q3 first option is not a clear statement 2/3 from which end? (8/10)

What is the difference between gastroschisis and omphalocele?
Gastroschisis and omphalocele (also known as exomphalos) are gastrointestinal abnormalities. They are the two most common defects of the anterior abdominal wall where gastroschisis occurs in 2.6 per 10,000 babies and omphalocele occurs in 2.1 per 10,000 babies [4] [5]. Gastroschisis is usually diagnosed around week 6 of gestation and the mothers are most likely to be under 20, undernourished and are smokers where as omphalocele is usually diagnosed 17 weeks into gestation and occurs predominately in women over the age of 30 [6] [7].
Gastroschisis is a congenital anomaly which affects the abdominal wall, most commonly in the area to the right of the umbilicus [7]. It is due to the lack of membranous covering over the wall causing herniation of viscera through the abdominal wall [8]. Gastroschisis is caused by the regression of the omphalomesenteric arteries which connect the yolk sac to the dorsal aorta [4]. However factors that also link to its occurrence include failure in mesenchymal differentiation, first trimester vascular accident and use of tobacco and illicit drugs [8].
Omphalocele on the other hand is the herniation of the abdominal viscera into the base of the umbilicus [6]. It is mainly caused by failure to complete lateral body fold migration leading to an open body wall and failure of the intestines to return to the abdominal cavity [4] [6]. Another cause includes the persistence of the primitive stalk [6]

Identify and write a brief description of the findings of a recent research paper on development of one of the endocrine organs covered in today's practical.
Mechanisms involved in glucocorticoid induction of pituitary GH expression during embryonic development.
Through the use of chicken embryos the study investigates the pathways in which glucocorticoids undergo to initiate growth hormone in the pituitary during embryo development. The research discovered the pathway namely the ERK1/2 pathway. The ERK1/2 pathway was stimulated by corticosterone treatment, however repetitive stimulation of the pathway was also found to suppress corticosterone thus suppressing the release of growth hormone. Corticosterone is the primary type of glucocorticoid in rodents and birds thus this knowledge was applied to glucocorticoids as a whole and provided the conclusion that the ERK1/2 is a strictly regulated cyclical pathway.
Somatotrophs are responsible for producing growth hormone in the anterior pituitary. Increased circulation of corticosterone lead to maturation of somatotrophs thus an increase production of growth hormone. The study also used exogenous glucocorticoids and found that it had the same effects.

Identify the embryonic layers and tissues that contribute to the developing teeth.
The embryonic origin of developing teeth are from the ectoderm and mesoderm layers of the trilaminar embryo coupled with neural crest contribution as well. Teeth are primarily derived from two types of cells, the odontoblast and ameloblasts. Odontoblasts are neural crest derived mesenchyme cells. They differentiate under the influence of enamel epithelium to form predentin which later calcifies to form dentin. On the other hand, ameloblasts produce enamel. Growth of teeth occurs in ossifying jaws and the periodontal ligament is responsible for holding the tooth in the bone sockets.

Group 1
The entire project is presented simplistically and all the content is relevant and easy to understand. Majority of the flaws I found were based around poor grammar and syntax which could be fixed up with some editing. Below is a more detailed breakdown of some of the things you could fix.
Firstly, I liked that the introduction was brief and concise and gives the reader a basic understanding of the topic of three person embryo. The video was also informative and provided some background information around the topic. I was informed that mitochondrial DNA was the major factor concerning this topic however there was a lack of information about its importance to the body so a short summary could be included along with some examples of diseases it could cause.
Also, the use of a timeline to present the history is a great idea and I think it could be improved and would look more aesthetically pleasing if it were to be placed into a table. I also think the 1990s, 2000s and 2010s label could be removed to make it look less clustered since they aren’t particularly necessary.
Some information under the heading ‘Technical Progression’ has yet to be filled in but from what is there I’d like to suggest exchanging the bullet points for numbering instead for the information under ‘Pronuclear transfer’ and ‘Polar body transfer’ since they sounded like sequence steps as opposed to separate points.
Finally, I found the layout of the table under the heading ‘Legal status’ to be very well put together. There are however some countries placed under the incorrect continents and I found that the order was easily changed and mixed up. I also noticed that several of the countries were linked to the same sources which made the information very unspecific. Instead of just links I think a few sentences explaining the legislation would be more informative.

This wikipage is very well put together. Your choice of headings, subheadings and tables and images is remarkable, it definitely makes the whole page flow very well. I particularly like the hand-drawn image which does a great job at simplifying the process of the pathogenesis of OHSS.
The introduction very concisely explains the contents of the page and I liked how it was finished off with a statement about the aim of the page. I thought it really brought the introduction together nicely. I can’t say much about the content except that it is very engaging and very well written so well done guys! Keep up the good work!
Some suggestions I have that could improve your page include adding more images. It would be nice to have some graphs to complement the statistical date from the epidemiology. Also, in some of the paragraphs e.g. in the last paragraph of ‘Epidemiology’ there isn’t a citation that accounts for the information at the end of the paragraph so that should be fixed.
