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…

Planaria are triploblastic acoelmate flatworms that inahabit marine and terrestrial environments and belong to the phylum Platyhelminthes. Though they are relatively complex creatures, as they possess an extremely branched gastrovascular cavity, a brain, hermaphroditic reproductive abilities, Planaria are best known for their regenerative capabilities (Rink, 2012). This is not a recent discovery, however. Peter Simon Pallas first described this regeneration 230 years ago in 1766, and Dalyell…

professor of pathology at Wake Forest University School of Medicine, writes, “The fact that Jesus became a human being at the moment of conception reinforces that all human stages have inherent value” (qtd. in Clemmitt). Although they are at early developmental stages compared to other human life, they should still receive the respect and honor that adult human beings receive (George and Lee 66). There is no reason that embryos should be massacred in embryonic stem cell research, as they harness…

One of the most debated topics in science is the use embryonic stem cells in scientific research. The ethical debate surrounding embryonic stem cell research comes down to two core values that we want to uphold: the alleviation of human suffering and preserving the inherent value of human life. Embryonic stem cell research is such a tricky topic because it requires us to choose between these two core values. We cannot uphold both values because the alleviation of suffering in this case is…

Embryonic Stem Cell Research Argumentative Paper If you were diagnosed with an incurable disease, would you do everything in your power to save yourself? Would you want to have access to a potentially life-saving treatment? A paralyzed man after a terrible car accident, regained the use of his arms after an experimental clinical study using stem cells (Aldrich). A (now), 5 year old girl suffering with SCID, was completely cured. These successes are just two, that represent the capability of…
