Do you know how many animals were used in animal experiments? The research found out that there are more than 26 million animals that were used in animal experiments! This number sounds scary to me. Out of this 26 million animals, 95% are rodents, and ONLY 5% were intellectual animals. The reason why they do animal testing is because they want to find cures for humans. For nearly 100 years, medicines were improved so drastically because of the animal researches and experimental results. The…

For this assignment, the virus that I chose to research further was the rabies virus, from the genus Lyssavirus. The rabies virus is a single-stranded RNA virus with a cylindrical structure that is covered by a layer of matrix protein. Its lipoprotein envelope is scattered with rabies glycoprotein-carrying trimeric spikes. This glycoprotein envelope can also influence the rabies virus virulence. The article I read also covered the pathology of the rabies virus, prevention strategies, vaccines,…

I am unusually nervous as I dive into the icy waters. With closed eyes, I put my mask on after the regulator retrieval. I open my eyes and freeze as water gushes in, burning my cornea, blurring my vision. My mask is upside down! Panic seizes me. Water floods my nostrils as I inhale through my nose, forgetting the regulator! Confusion and discomfort overpower me as I fin desperately towards the surface. Ivor, my instructor, tries to hold me by my weight belt, trying to take off my mask and flip…

nerve for damage and any other eye problems. Another test that is done is called Tonometry. This measures the intraocular pressure inside the eye that can lead to glaucoma. Pachymetry is done to measure the thickness of the cornea. This test uses ultrasonic waves to measure the cornea. With all of these tests a solution that numbs or dilates the eye will be…

The five main senses are something that can be seen as simple, but complicated at the same time. Every single day of your entire life your senses have not only made you aware of your surroundings, but has also made connections and memories through what you see, smell, taste, touch and hear. All work together to make life something more than it really is. Throughout learning about every single sense, you can see the consistency of how our senses work together to understand safe and hazardous…

ENG 380T – Literature and Medicine Nicole Radova The Bionic Eye: A Collaborative Vision “Seeing is believing” – an idiom commonly uttered and heard in today’s Western world. Sight has been deemed the superior sense in our society since its association with knowledge acquisition in the eighteenth and nineteenth centuries (Classen 1997, 402), which the Scientific Revolution directly preceded. Yet available to us are four other senses, which itself is not an ultimate truth as the very concept…

In countries all around the globe, children and young adults sell their bodies, are abused, work like animals, and even have their organs removed all for the profit of strangers. Many people believe that Human Trafficking only consists of teenage girls, when little do they know, it involves men as well as many small children, and even victims of older ages. Also the assumption is that all Human Trafficking is just for sexual exploitation, when there are many more aspects that can fall under…

Ichthyosis is a rare genetic or acquired skin condition, classified under the “Disorders of Cornification” (NORD's Rare Disease Database, 2005) and is characterized by dry, thickened and scaling skin. There are many different forms of Ichthyosis, with some acquired types, disguisable from one another by the extent of scaling, the presence of reddening skin, how it was inherited and the associated abnormalities. Ichthyosis is a lifelong disease to which there is no cure. Ichthyosis may be…

vision. The short-term consequence is a possible road accident, while chronically dry eyes can cause dry eye syndrome. Dry eye syndrome is the condition where the eyes don't produce enough tears. Without moisture and lubrication, the cells of the cornea would dehydrate and die. Tears help small eye wounds heal and contain antibacterial and antiviral agents that fight off infections. All of these functions are diminished in people with dry eye syndrome. If you hike in outdoor environments with…

The roaring of the loud crowd surrounds me like an ambush of tigers sucking out my inner anxiousness to paint an impeccable picture of itself on my face. I feel the adrenaline rushing in my blood and crawling creepily at the speed of light to the blood vessels in my face. My temperature rises as if my cheeks were slowly absorbing the heat from a hot stove. I support the weight of high expectations on my shoulder from myself and my family. I get onto my starting block and after every second…
