of Stem Cell Research The ethics of research involving fetuses or material derived from fetuses have been widely debated for over three decades, portrayed by its proponents as holding the key to scientific and medical breakthrough and by its opponents as devaluing the most basic form of human life. The latest chapter in this long saga involves the use of embryonic stem cells. Research in this field took a great leap forward in 1998, when the first successes in growing human stem cells in culture

2017 Stem Cells Many people around the world like the idea of stem cells, but are they really a good thing? Stem cell research is debatably the worst way of solving problems with the human body. In fact Scientists have been researching stem cells for a very long time, since 1956 when the first successful bone marrow transplant was made by Dr. E Donnall Thomas. There are not many cons to not use stem cells but they are very important to consider. Stem cells should not be used in the medical field

nanometers long. RNA is only 1% of the mass of the virus. The large virus structure is composed of three compartments the nucleocapsid, the matrix space and the envelope. The central core of each filovirus virion consists of the single RNA genomic molecule and its adherent nucleoproteins NP and VP30 (the nucleocapsid). They are linked by matrix proteins VP24 and VP40 to the inner surface of the lipid bilayer of the viral envelope, which is derived from the host cell. Trimeric spikes of the surface envelope

Introduction Ultrasound is acoustic energy with a frequency at about 20kHz which is above the capability of human hearing. It is more commonly used in the medical field than food industry. In the medical field, the most significant usage of ultrasound is in sonographic scanners. As these scanners work at 2-18MHz, it produces smaller wavelength which is able to make sonogram of smaller details. As such, ultrasound sound based imaging technique is used to visualize body structures and tissues (Carovac

Stem cells have the potential to impact the medical field changing the way we see science and medicine. It’s necessary to understand stem cells, the possible uses and differences. Stem cells transform to certain tissues types depending on the ones surrounding them. Certain stem cells have the ability to repair damaged tissue, which in long term can impact those with severe medical conditions. Like any other medical field. Stem cell research is very complex and consists of various data. Stem cell

evolution of indued pluripotent stem cells and how these developments will impact the medical field. Beginning with a comprehensive exploration of the history and discovery of stem cells, it will highlight the challenges historically faced by researchers and medical professionals prior to the discovery of defined factors in adult cells. Using published research for reference, it will describe the process of discovery and modern application of induced pluripotent stem cells, leaning heavily on the original

lot of advancement. Regeneration is a field that focuses on curing chronic diseases. Some advanced clinical trials so far is trying to regrow muscles on soldiers who were wounded in an explosion. Another treatment being studied is to extract a few cells from a person body and grows them in a large quantities in the laboratory. Once a specific number have been produced, the investigators inject them back into the patient. One of the current uses is Limb Lengthening this current use is when people have

Stem Cell Research Stem cells are cells that have the ability to develop into specialized cell types during the early stages of their lifetime. There are many different types of stem cells being developed currently. The first type of stem cell is the mesenchymal stem cell; which are cells that are found in bone marrow and are very rare. These stem cells can serve as many different types of specializes cells, such as bone cells, fat cells, and cartilage cells. Next, there are multipotent stem cells

x PDG stands for Pre Implementation Genetic diagnosis it is a technique used to help examine and recognise a specific genetic defect within embryos created using IVF (In-Vitro Fertilisation). This technology is performed to prevent disorders or diseases being passed on to the child. The ultimate aim for couples attempting to use PGD is to produce an offspring free of chromosomal genetic defects. In New Zealand this technology is very limited and every application must be sought through and gain approval

potential of adult stem cells has been reported, especially with stem cells derived from bone marrow and adipose tissue (Planat-Benard et al., 2004; Tang et al., 2006; Uysal et al., 2010). Stem cells are defined by their capacity to self-renew and differentiate into multiple cell lines; they are divided into two main groups: Embryonic stem cells and Adult stem cells (Behr et al., 2010). Embryonic stem cells are pluripotent cells produced from the inner cell mass and can differentiate
