Problems of Stem Cell Research Essay

fascinating study of stem cells and tissue regenerations. The regeneration of the planarian may require the planarian to reshape its form by finding the right proportion to acquire the right shape and size of its body to form a functional, bilaterally symmetrical anatomy. The regeneration period can vary with different species, some may take as short as a week to fully regenerates its body proportion while other may take longer. The model organism, Dugesia, is composed of adult stem cells that…

1) What is the question the authors are trying to answer? - The authors are trying to determine if progesterone would make a difference on the quality of the embryos during the growing stage of the first follicular wave. 2) What is the hypothesis of the study? - The hypothesis of this study is that if a person were to induce a cow to ovulate follicles during the first follicular wave, that would minimize the embryo quality due to progesterone concentration at the time of growing the follicle…

and therefore can charge a monopoly price. The second point is the the gene patents get in the way of research so that people won’t get healed or treatment because of them blocking test and treatment. That similarity ends in the middle of the article. He cites lawsuits and several news articles that show the benefits of gene patenting. The citations include “ little evidence emerged that research laboratories were hemmed in by gene patents”, “prices of patented and exclusively licensed tests are…

patients) or Trastuzumab (HER-2 positive patients). The IHC biomarker c-kit (CD117), which is used in the clinic to detect gastrointestinal stromal tumours (GISTs) (Debiec-Rychter et al., 2004), and p63, which is used to detect the presence of basal cells indicative of normal prostate glands (R. B. Shah, Zhou, LeBlanc, Snyder, & Rubin, 2002; Weinstein, Signoretti, & Loda, 2002), are the latest FDA approved single marker IHC-based assays which were approved almost a decade ago in 2004 and 2005,…

Human embryonic stem cells (hESCs) continue to be a leading topic to scientific discussions due to their potential medical advantages. Embryonic stem cells originate from gathering and culturing the cell mass from a blastocyst stage embryo developed via in vitro fertilization in specialized fertilization clinics. Human stem cells are great for utilization in clinics and research about the development of the human body. This work consists of identifying how undifferentiated stem cells become the…

donor. Additionally, the patient’s own cells would be able to be seeded into the scaffold to reduce the chance of rejection. Biocompatible scaffolds have shown great promise…

classification \cite{huanhuan2014classification, wulsin2011modeling, turner2014deep, zhao2014deep}, brain decoding and emotion classification \cite{freudenburg2011real, an2014deep, li2013affective, jia2014novel, zheng2015revealing}. There is aslso research on patients suffering from schizophrenia \cite{plis2013deep} and Alzheimer’s disease \cite{taigman2014deepface}. One area that can lead to progress is figuring out how to encode raw data to be fed to the networks, so that DNNs can learn…

of Life: Embryonic Stem Cell Research In Beau Watts' essay "Embryonic Stem Cell Research: A Moral Evil or Obligation" (December 2011), the author claims that embryonic stem cells are the answer for humanity to have an overall better life. Watts, an emergency room physician in Kansas City, Missouri explains the complex properties of embryonic stems cells while also discussing the properties of other proponents for altering genes, such as embryonic germ cells, and adult stem cells. He highlights…

Blewitt text and the reading by Sylwester. Broderick and Blewitt open the chapter by explaining the intricate process of how the brain is formed and how it develops throughout gestation. Once the brain structure itself has formed in the womb, nerve cells called neurons begin to form (Broderick & Blewitt, 2010). The brain sends information to the rest of the body through neurotransmitters that are housed in terminals at the end of axons (Sylwester, 1995). Sylwester gave an interesting analogy…

From stem cell research to cryonics to artificial organs, mankind has gained immense knowledge.Considering today's circumstances with research done, the possibility of Frankenstein's monster being successful is much more…
