Fluorescence

• Clinical Appearance This refers to any specific signs and symptoms that are related to the development of an infection or disease. The appropriate description of the clinical appearance often leads to a diagnosis of the illness. • Stained culture/histology examination False coloration of a substance to aid in the inspection of tissues, microorganisms, or other cells under a microscope. • Tests for antibodies to the microorganism Antibody tests rely on on the fact that there are specific…

resazurin is going to be using an oxidation-reduction (REDOX) indicator that will undergo a color change due to the response of the cellular metabolic reduction. “The reduced form resorufin is pink and highly fluorescent, and the intensity of fluorescence produced is proportional to the number of living cells respiring”, meaning that there will be a color change when introduced to a cell (Bio-Rad, n.d.). In more simple terms, the cell will have a color change due to the Alamar Blue penetrating…

We started off Wednesday, knowing we would be covering a topic that was completely new to pretty much everyone attending. We were covering transposable elements. These were first discovered by Barbara McClintock in corn kernels. She noticed that the corn kernels were either colored, or plain- but once in a while they were spotted. Most scientists at the time assumed that the chromosome for color had been repressed or had broken off. However, Dr. McClintock felt that if the chromosome had been…

Restriction enzymes are used to manipulate DNA sequences to create recombinant DNA by first cutting up the foreign DNA in order to protect the bacteria cell against invading DNA from other organisms. The enzyme is very specific when it comes to identifying a specific DNA sequence. When the enzyme identifies the specific DNA sequence it cuts both DNA strands at specific points at the restriction site. Lastly, the DNA ligase joins the DNA from two different sources and produces a recombinant DNA…

Abstract In this article, an analytical simulation based on a new model incorporating surface interaction was conducted to study the slip phenomenon in Couette flow at different scales. The velocity profile was calculated by taking account micro-force between molecules and macro-force from the viscous shearing effect, as they contribute to the achievement of slip length. The calculated results were compared with those obtained from the MD simulation, showing an excellent agreement. Further, the…

The nature versus nurture argument is, and has been, one of the most hotly debated topics in modern science for decades. The argument of whether humans start out as a “blank slate” or Tabula Rasa, as opposed to being predisposed with certain environmental effects out of their control transcends even natural science and enters into the realms of philosophy and psychology. It is nearly undeniable that the ideas of Mendelian inheritance are sound theories, yet the argument for…

Genetics To Down Syndrome Genetics describes the makeup of our cells, genes, chromosomes, and phenotypes. When there is alter in a gene or a duplication of a chromosome, it can lead to a certain diseases. One of the main diseases known today from a duplication of a chromosome is Down syndrome. John Down first put a name to Down syndrome in 1866, but artifacts from Mexico and Saxon documented some cases of Down syndrome in individuals, and also some were found in paintings of the Renaissance in…

Implementation of optical fiber sensor in biomedical Optical fiber sensor for biomedical application Applications for biomedical sensors can be named in vivo or in vitro. In vivo alludes to application on an entire, living life form, for example, a human patient; in vitro alludes to testing outside the body, for example, research facility blood tests. From the point of view of how sensors are connected to a patient or organic framework, they can be named noninvasive, reaching (skin surface),…

move closer to the red end of the spectrum. This explained why the jellyfish were studded with green lights, even though aequorin’s flash is blue. This kind of reaction—where light with more energy is made into light with less energy—is called fluorescence. In the wake of this discovery green protein was renamed green fluorescent protein, or…

A career in cancer research has been my objective since before I entered college. My extensive personal experiences with this disease have deeply impacted my goals and aspirations as both a scientist and as a student. Unlike many undergraduates, I have accumulated an extensive amount of research experience during my undergraduate career, working to answer a broad range of biological questions. These diverse experiences have directly impacted my decision to pursue a graduate degree in immunology,…
