    nanoparticles in samples were visualised. Bio-distribution of nanoparticles in samples was also observed by the confocal fluorescence microscopy, hyperspectral fluorescence microscopy and transmission electron microscopy imaging for confirmation purpose1. Bioluminescence observation suggested a significant proportion of samples were successfully labelled with nanodots and they can be clearly visualised in all three different experimental conditions: in vitro (labelled spermatozoa and oocytes), ex vivo (intrauterine labelled spermatozoa), and in situ (labelled follicles during its maturation process)1. Migration locus for labelled nanodots were also observed during their incubation and growth period. Images suggested nanodots tend to accumulate in area with high levels of plasminogen, a fertilisation regulator1. In female reproductive track, the oviduct section showed higher nanodots intensity compared to the uterine horn1. However, the in situ did not give adequate information for the study and an optimised strategy is needed1. All bioluminescence observations above have high consistency with the data from fluorescence and hyperspectral imaging, which entails quantum dots labelling was able to be used as a novel bio-imaging method in studying dynamic changes happened over cell activities1. In a word, this technique gives a new pathway in embryology and gamete maturation study. Traditional embryology study use ex vivo or transplant as main research method. For ex vivo…

  • 'Medical Ethics In Henrietta Lacks'

    A quote to highlight the misuse of medical ethics is “TeLinde disagreed— he believed carcinoma in situ was simply an early stage of invasive carcinoma that, if left untreated, eventually became deadly. So he treated it aggressively, often removing the cervix, uterus, and most of the vagina” (Skloot 165). This was unethical because there was no proven way to tell if this was the best treatment method, he did it just because he thought it was best. This is an example of a doctor using his own…

  • Negative Effects Of Zoos

    mention, they participate in internships at animals sanctuaries, animals camps, and veterinary hospitals. When handling these exotic animals, zookeepers do it with care as they were trained to so. These zookeepers maintain the animals’ habitat and also engage them in activities. Care has improved a lot over the last few decades mostly because of the improvement in education that zookeepers attain. They now understand that animals need to be kept busy and active in order to prevent boredom and…

  • Neurofibromatosis Type 1: A Case Study

    several molecular genetic tests for NF1: Comprehensive multistep mutation detection, Genomic DNA sequence analysis, Deletion/ duplication analysis, and Cytogenetic analysis. The comprehensive multistep mutation detection protocol has been effective in detecting 95% of individuals with a pathogenic NF1 variant while Genomic sequencing, deletion/duplication analysis, and Cytogenetic analysis have only been able to detect a defect in the NF1 gene in 61%, 5%, and less than 1% of individuals. The…

  • Exotic Animals

    animals, across 22 different zoos, were analyzed to determine reproductive success and overall species population health. Data demonstrated a positive growth curve for 107 of the species examined, with a 0.0281 median rate of population increase per year, while only 17 species (14.4%) demonstrated a negative growth curve (Alroy, 2015). Although growth rates are indicative of declining, or increasing population, they can be misleading if taken at a superficial level. Populations of certain…

  • Against Zoos Essay

    Have you ever been to a zoo? Zoos are very popular and everyone has been to at least one, at some point in their life. They are known for showing off the wild animals, and educating you on them at the same time. I don’t think zoos do very well with that. To me, a zoo is a large business that captures wild animals and changes their lives forever. They hold them in captivity and don’t treat them like the should, like wild animals. Many zoos are businesses and known for only caring about the money,…
