Embryonic Stem Cell is Pertinent to Finding Cures Diseases, sicknesses, burns, and infections: how can this world ever be cured? It was not until recently in 1998 when a promising cure was discovered, the embryonic stem cell (ESC). According to Christine Watkins in one of her social issues books titled Human Embryo Experimentation, ESC was discovered by both James Thomson at the University of Wisconsin and John Gearhart at the University of Pennsylvania (10). Thomson, a director of regenerative…

cell research as a practice that “…devalue[s] and violate[s] human life at any stage from conception until natural death,” a majority of the embryos used in stem cell research are produced “in vitro,” meaning that they are grown in a test tube or petri dish. From this, it can be said that the embryos used in stem cell research are not necessarily “alive,” since the embryos being used have no set definition to whether they are property or people. As the embryos lack certain physical properties…

Introduction: In many cases in industry, it is necessary to separate a mixture or solution. In environmental testing, they look for PCB’s in oil, and pesticides in ground water. In the food industry, they can test additives to determine concentrations of preservatives, vitamins, proteins, and amino acids.2 Chromatography is the process of separating a mixture, and has many different applications throughout the world. There are a variety of ways to conduct chromatography including column…

the beginning, but with practice, the emotion and passion will develop. Cross-generational “As people live and work longer than ever before, the modern office now houses up to four wildly different generations under one roof - and it can be a Petri dish for problems.” -Jenna Goudreau 5. He’s misstra know-it-all Whether the organization is suit and tie or jeans and hoodies, communication styles vary among generations and the differences can create tension (Goudreau, 2013). Younger employees…

The year 2016 is one of the worst and stupidest years in American history, but at least frail, sickly, and old Hillary’s recent collapse helped restore America’s faith in the power of love. The moment Bill heard that she was sick he rushed to his woman’s bedside. And then, as soon as he was finished, he picked up the phone and called Chelsea’s apartment to see how Hillary was doing. Where was Bill in all this anyway? Even if some media hack had suffered an unexpected bout of Sudden Onset…

In the article “LSD Literally Gets Stuck Inside Your Brain,” Claire Maldarelli explains the neurological effects of LSD and highlights a new study about potential pharmacological advances due to LSD. Brian Roth, one of the study’s authors, is a pharmacology professor at University of North Carolina at Chapel Hill. He is studying the neurological effects of LSD and the drug’s properties. LSD is unique among other hallucinogen drugs; its effects are last the longest, clocking in at 12 to 18 hours…

Vibrio Fischeri, Rachel Brown: BM304 Revision Guide 2016 Physiology: Vibrio Fischeri are Gram negative, motile rods. One of the key features that can be found in the species Vibrio Fischeri is its bioluminescence. This bioluminescence comes from one of the products of a reaction catalysed by the enzyme luciferase (see biochemistry and metabolism). Vibrio Fischeri are easy to grow and they display chemotaxic behaviour. It is best to grow Vibrio Fischeri at 28 degrees Celsius. (DeLoney-Marino CR,…

longer essential. Now scientists do not have to test animals or humans to examine the care of products. Recognitions to these supplementary alternatives, scientists can use vitro testing. “Thanks to Vitro testing, which involves studying cells in a Petri dish, we can identify how cells might respond to drugs without actually having to use a live creature of any kind” (Klazema). Vitro testing uses human cells, giving extremely reliable results and is not at all dangerous. Using alternative tests…

For example, in glass testing such as the study of cells within a petri dish, can produce more reliable and relevant responses than animal testing as actual human cells can be used. This significantly reduces the risk of unreliable results as the researchers can see the direct and indirect effects a chemical, medication…

where half of the solution disappears. These steps are then performed until only 15 mLs of the solution remains. With this remaining solution, “2 drops of new methylene blue” are put into the solution. Lastly, the solution is placed in a “gridded Petri dish or several coverslipped microscope slides” under the microscope (The Merck Veterinary Manual, 2015). 10) Sedimentation typically gives better results when testing for flukes because flukes cannot really float, so by performing the fecal…
