Hematopoietic stem cell transplantation

The disease is caused by unequal crossing over is the Alagille syndrome. Its signs and symptoms depend on which part of the body it affected. If it affects the liver, its signs and symptoms are jaundice, itchy skin, and xanthomas. Most people who have this disorder usually “have distinctive facial features including a broad, prominent forehead; deep-set eyes; and a small, pointed chin” (NIH, 2016). This disease is associated with other diseases such as pulmonic stenosis and tetralogy of Fallot.…

fastest growing career since 2010 and is expected to grow by 14% in 2020. Biomedical engineers created the first bionic arm which helped lead up to the inventions of artificial organs such as: bladder , bone , skin , kidney , contact lenses, and brain stem implants , these are all bionic. Currently biomedical engineer are trying to figure out ways to regenerate spinal disks , the creation is given by a syringe into the area without a disk and the substance turns into a gel like…

In scientific terms, aging is referred to as “senescence”. Senescence is the process where cells fail to sufficiently replace the older cells, thus reducing the body’s functional capacity. (merriam-webster, 2016) It appears counter-intuitive for evolution to engineer organisms with a limited life span. However, it is not the intent of evolution to deteriorate our cells. The infinite number of outside factors that bring damage upon a life form are to blame. Our DNA can be harmed by radiation,…

Stem Cells To start off, a stem cell is an undifferentiated cell of a multicellular organism that has the ability to assist other cells of the same type. They come from developed organs and tissues in the human body. You may think of a stem cell as a “blank” cell because it has not decided what it wants to be. It might become a skin cell, heart muscle, nerve cell, bone cell, etc. The use of stem cells is a controversial topic. You can view the use of stem cells through different points of views…

means that the historical experiences from the parent’s life experiences can be passed down in the form of epigenetic tags. How does epigenetic marks overcome the reproductive barrier? Most complex organisms develop from specialized reproductive cells (eggs and sperm in animals). Two reproductive…

Why Stem-Cell Research is a Good Thing The world we live in is constantly debating over the ethicality of a multitude of issues. Typically they pertain to why something major could help an individual on a micro or macro scale but, often sacrifices something deemed morally or ethically wrong. These issues often divide us and can often cause complications. The first topic people usually think of when it comes to a situation is abortion. Since stem-cell research is loosely related to the abortion…

and Mutations article. In the article DNA and Mutations, scientists have found two different genetic occurrences in multiple individuals bodies called, mosaicism and chimerism. Chimerism involves a single organism who contains genetically distinct cells, which most likely come from a twin or a parent/ fetus. Mosaicism is when a single organism has two different genotypes within their body. The article explains this phenomenon through instances found on accident. But these incidences no longer…

physiology and biochemistry (82). It will allow us to test and compare the ability to repopulate livers with different cell sources which have had limited success in the mouse (3). Primary human hepatocytes have been shown to efficiently repopulate recipient livers (32), however with limited access to large quantities, researchers must examine whether other types of hepatic stem cells can act as potential donors as well. Having an efficient model that can be used to perform repopulation…

Lawrence Livermore researchers recently published a study about how shock waves will cause damage the membrane proteins for a patient suffering from brain injury. These shock wave TBIs have become common with improvised explosive devices that we have seen used in Iraq and Afghanistan. Experts estimate that around 230,000 military veterans have suffered from TBI between 2001 to 2014. The problem is that we do not deeply understand how this takes place. Researchers are not sure how exposure to…

By discovering something you’ve been wanting to since you were a kid, in this case proving aliens are real, you’ve been dreaming about this for as long as you can remember but this may result in losing your human life, is it really worth it? Maybe? It depends, in this situation if I personally was very passionate about discovering aliens or anything in that matter I would certainly risk all I’ve got, but be smart about it. I believe that if you are very passionate about that one thing then it…
