Lens Fiber Differentiation and its effects on certain organelles.

This writing exercise analyzes two separate but related scientific articles, “The fate of the Golgi Apparatus and the Endoplasmic reticulum During Lens Fiber Cell Differentiation” and “Coincident Loss of Mitochondria and Nuclei During Lens Fiber Cell Differentiation” both which analyze and study Lens Fiber Differentiation. The writing assignment will be based on four sections:(1) Background of the research (2) Methods used to approach the study (3) Results obtained; and, (4) Concluding both articles. Background Before one starts this scientific journey it is apparent the individual should have some basic knowledge regarding what lens fiber is and which part of the

Lenses and vitreous body were removed from the embryos from day 6-20. The vitreous body and lens are then transferred to a petri dish where they would be separated by doing a careful disection. Dr. Mark Adeelman donated the rhodamine-123 for the study which was used a methanol stock. This stock was used for the fluorescent probes. In order to be able to examine the lens with the confocal microscope one needs to stain it with the fluorescent dye. This process didn 't seem to work accordingly therefore another method was adapted lens slicing. Article two states that although cell on the outer layer of the slice was being damaged there were tons of cells located deep inside the cell that were able to examine. Rhodamine-123 was also used in this process. once the lens was stained with the rhodamine-123 it would enter stain the mitochondrial matrix. Next they rinsed the lenses with saline solutions for it to be looked under the confocal microscope to view the mitochondria and nucleus. After staining the slice they treated the tissue with 4% formaldehyde and 0.05% ethidium bromide in a NaCl solution. In some of the experiments it was evident actin was visible under the fiber

    The eyes include the receptors for vision, which is generated in the retina. Processing pathways of eyes are like a camera, and what difference is people generate information on their sensitive retina, not camera films. Retina has lots of cells that cover the inside back of the eye. The image leaves on eyes by optic nerve; Cornea is responsible for focusing light to be processed; Fovea is the center of macula to sharpen our vision views for focusing; Iris regulates the amount of light, which along with the pupil; Lens focuses on light rays. Visual pigments have rods and cones,…

    , The fact of this change over time can be laid down solely to DNA and gene shuffling. It is empirical fact, backed by undisputable evidence, that everytime offspring of a species is produced, the DNA and genetic information are very slightly changed due to errors made in DNA replication. This process, over time, is what creates changes in species, and in the long run, is the cause of evolution. With this taken into account, the most probable way the eye developed was a growth of light sensitive cells, which grew through a random genetic mutation. Over time, random mutations gradually caused an eye socket shaped structure to form layers in light receptive tissue, which could tell which direction the light was coming from.…

    There were five cells observed while conducting the experiment. The five cells consisted of cardiac muscle, elodea (a plant), paramecium (a protist), rhizopus stolonifer (bread mold, a fungus), and Bacterial cells (bacilli). Each cell was observed under high power lens (except for rhizopus stolonifer) with a total magnification of 400μm and a dFOV of 400μm. The estimated object size, scale bar, and drawing magnification of each cell was found except for cardiac muscle. Each cell appeared much larger under the microscope allowing each cell to be viewed and observed closely.…

    1.The most significant thing I learned last week was the Four Lenses lesson principle. In this lesson, I learned about the different temperaments, colors or preferences that make individuals unique on our own way and that every person was born with a pre-deposition temperament. The Shipley communication assessment was fun; the result was shocking because it shows that my previous secondary color blue is now my primary color and my previous primary color gold is now my secondary. By knowing the different colors, it will help how I communicate and approach people with a different preference. 2.…

    The cornea, or lens, is a transparent covering of material at the front of the eye, which creates an image of an object by mixing light in a process known as refraction (Klein). During refraction the light rays pass through the cornea and pupil and hit the lens that creates an image on the retina. The retina then sends the image to the optic nerve that makes you able to see. The eye can work like this because it has its own lens that is able to focus on an image that is given to the retina. Since your pupils grow and shrink, depending on how much light is present, the image that is given to the retina may be larger, smaller, or the same size as the object (Roberts).…

    Watching my close relative suffer with strabismus throughout her childhood made me realise how sight deficiency can lead to severe physical and psychological effects in someone. Empathising with her struggles from an early age made me aware of the reliance on our eyesight. Ultimately I was motivated to attend a talk regarding optometry which enhanced my knowledge of the course and gave me a chance to operate optical instruments. Acknowledging my ambition beforehand made me choose A-level subjects related to optometry.…

    Much like other displays of power, the same lenses we flaunt to remind ourselves how chic we are, unavoidably expose our hidden shortcomings and insecurities about the world around us (Cohen,2014). The telescope which was one of the central instruments of what had been called the scientific revolution of the seventeenth century revealed the unsuspected phenomena in the heavens. It was not until the completion of the thirteenth that lenses existed as they are today, even though their properties of convex plus concave clear items had long been known. Glass of reasonable quality had become relatively cheap and in the major glass-making centers of Venice and Florence techniques for grinding and polishing glass had reached a high state of development.…
