Reading Paraphrastically: Ethics of Stem Cell Research Summary of website: Ethics of Stem Cell Research is a website that describes why stem cell research may be viewed as morally wrong. The argument focuses on a number of viewpoints that is mainly focused on human embryos. The article’s discussed why individuals may not support stem cell research that involves human embryos. The website has several points that show the viewpoint of individuals against stem cell research and possible counter…

Stem Cells and their Possibilities “It makes you select between two moral principles: you should respect the value of human life; or you should do something to alleviate suffering.”-Pros and Cons of Stem Cell Research Stem cells are a type of cell that has the ability to change into any type of specific cell that is needed. These cells are essential in research regarding regenerating muscles, bones, limbs or any other body part that has the possibility of regeneration. Organs generated from…

It was the day I had to set up an interview with an expert on the topic that I chose, stem cell research. After many google searches and phone calls I decided to interview Dr. Aaron Garman, a Family Medicine Practitioner who lives in North Dakota. Dr. Garman graduated from the University of North Dakota School of Medicine and Health Services and has been practising in the field for 20 years scense. I chose Dr. Garman because he is a doctor and occasionally works on or sees stem cell research…

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…

The transplantation surgical procedure was an extreme brake-thro in history. One of the earliest transplants that was done was an Autograph transplant that was a replant reconstruction of the skin on the nose and was performed by an Indian surgeon (Shrutas) in the 2nd century BC. This technique was next vitalized in the First World War. The first organ tissue transplant as we know it was done by a Swiss surgeon called Theodor Kocher. He removed a Thyroid from a patient, but then noticed that the…

Tissue engineering scaffolds aim to completely reproduce the anatomical structure and environment of part of the organ or the entire organ itself. This is an extremely promising method as it would serve as a readymade transplantable kidney or section to replace a damaged one that would also mimic the in vivo 6 environment. Two of the most common methods of developing scaffolds are decellularized organs and biocompatible polymers. The advantage of developing a whole scaffold would enable an…

device made of plastic – the first UK patient to be discharged after having both sides of his heart replaced. How is that possible? The development and operation of these life-saving devices requires understanding and application of a combination of biology, materials science and physics. Today the artificial heart remains an important lifesaver for many patients. As of now, almost…

Over the past few decades a lot of biomedical information has been gathered (in the form of images, signals and sequences) and there is a great deal of knowledge that can be gathered from the raw data \cite{manyika2011big}. The biomedical imaging data consists of magnetic resonance image (MRI) \cite{edelman1993magnetic, ogawa1990brain}, radiographic image \cite{hsieh2009computed, chapman1997diffraction}, positron emission tomography \cite{bailey2005positron} and others. Biomedical signaling data…

Stem cell research is one of the most controversial subjects to face the world since abortion, yet stem cell research could be the key to unlocking a cure to the deadliest diseases affecting mankind. While stem cells have vast promise for both medical issues and for future approaches such as slowing down aging, scientists are still in the beginning chapter of the stem cell revolution. Stem cell research and the use of stem cells in therapy is a complex multi-step process that requires scientists…

Introduction All animals can heal their wounds. However, some animals can even regenerate lost body parts. Questions have arisen such as, how does this process take place? What is necessary for these animals to perform this job? Experiments have shown that different animals regenerate in different ways. Some may be similar than others and it may have an impact on their lives. The purpose of regenerating tissues is to limit damage and loss of infection. The processes of tissue regeneration…
