Nanotechnology and plastic surgery Nanotechnology is defined as the science of design, synthesis and characterization of matter at the nanoscale, which mesures one billionth of the meter [1,2] On that scale, structures exhibit novel chemical, physical and biological properties and processes, which enables the creation of engineered nanomaterials (ENMs), with various characteristics and potential applications. [3] It’s not just that though. Nanotechnology shows the ability to eliminate the gaps
Brain Cancer: A Cumulative Overview “According to a recent estimate by WHO even though brain cancer occurs quite infrequently, it develops in about 22,000 new people every year along with 13,000 estimated deaths” (News Pointe). The definition of the word cancer is, “a disease in which abnormal cells divide uncontrollably and destroy body tissue.” More specifically brain cancer is a mass growth of abnormal cells in the brain. This is a very interesting disease because it attacks one of the most important
Cancer is a class of diseases characterized by uncontrollable cell growth. Colon cancer forms when cells in the large intestine grow uncontrollably. Most colon cancers come from small, benign tumors known as adenomatous polyps that form on the inner walls of the large intestine. Some of these polyps can grow and become malignant colon cancers over time if they are not removed during a colonoscopy. Colon cancer cells will invade and hurt healthy tissues that are near the tumor creating a lot of problems
Hairball A solitary woman sits in conversation with a benign tumour that had just recently been removed from her ovary. As the woman speaks, the inanimate tumour, which she has named Hairball, looks on from its glass encased perch atop the fireplace. The scene is macabre and certainly unusual, but such is the life of Kat, the main character in Margaret Atwood’s short story, Hairball. Kat’s life is filled with the unusual and the shocking, a lifestyle that has been self-imposed. Throughout the
Hyperplasia is the early stage development of cells to cancer cells. It increases in cells that have the capability to proliferate at a fast rate. Often times, hyperplasia is correlated with the increase in proliferation and the speed of mitosis. The increase in the number of cells with hyperplasia means that the proliferation is happening at a faster rate than normal. Hyperplasia is considered to be the early stage of dysplasia, though not all hyperplasia leads to dysplasia. In this experiment,
A spinal tumor is an abnormal mass of tissue within or surrounding the spinal cord and/or spinal column. These cells grow and multiply uncontrollably, seemingly unchecked by the mechanisms that control normal cells. Spinal tumors can be benign (non-cancerous) or malignant (cancerous). Primary tumors originate in the spine or spinal cord, and metastatic or secondary tumors result from cancer spreading from another site to the spine. Spinal tumors may be referred to by the region of the spine in which
Enzymes can be considered as the machines that carry out the majority of the chemical reactions that take place inside our body. These unique enzymes provide the work that is being done inside the cells. For over a century, scientist have been studying and experimenting with these proteins. Enzymes can be associated with a number of different things that take place in the body. For example, an enzyme can be the root to cancer cells. Researching about these highly chemically reactant enzymes has led
Summary of Metronidazole Article: Bacterial vaginosis is one of the major contributors of vaginal infections during pregnancy and accounts for 40 percent of these cases. Generally, bacterial vaginosis is associated with several obstretic complications like pre-term labor and delivery, untimely rupture of membranes, postpartum endometrisis, and chorioamnionitis (Wang et. al., 2010, p.444). Metronidazole has traditionally been used as the drug of choice in the treatment of bacterial vaginosis because
“Human Herpes Virus-8 (HHV-8) and Kaposi’s Sarcoma (KS)” Human herpes virus (HHV-8) poses a challenging task for researchers determining its role in Kaposi’s sarcoma (KS). People with KS are distinguished by their placement in four categories. The first category consists of elderly males of Mediterranean or Eastern European Jewish descent. The second category consists of individuals of all ages from Africa. Neither one of these categories is associated with immune deficiency or known environmental
susceptible to the development of cancer at some stage of their life. Among all types of cancer, squamous cell carcinoma is one of the skin cancer that commonly affects domestic animals. Cutaneous squamous cell carcinoma is a type of cancer caused by neoplasms arising from the squamous epithelium of an animal regardless of species. However, this essay will only focus on this condition among felines since my chosen species is a white cat called Rosie. There are several forms of cutaneous squamous cell carcinoma
category of neoplastic diseases of the skeletal system. It is a pathology that arises from bone-forming cells that line the medullary canal. These bone-forming cells are responsible for thickening, ossification, and regeneration of new bone growth. This neoplasm forms in the growth areas between the epiphysis and diaphysis, the area of most metabolic activity. Osteosarcomas form primarily in the long bones of the body with 74.5% of the cases being in the lower long bones, and 11.2% being in the upper long
My sister, Kathy, was diagnosed with cancer in 2013. I was shocked because my sister was always the healthy one among all us girls, the type of cancer, Kathy called colon cancer, Cancer that forms in the tissues of the colon. Most oncogene mutations of indisputable normal genes designate proto-oncogenes. Proto-oncogenes determine the “excellent” genes that usually rule what cell do and the way typically it distribute. Once a factor mutates (changes) into cell, it come back a "hurtful" factor that
melanin. Melanin is what protects your skin from over exposure to the sun’s ultraviolet rays. Over exposure of sunlight can reduce the melanin’s ability to absorb the sunlight and damage the skin. (2) Neoplasms are abnormal growths of new tissue. They are described as benign or malignant. Benign neoplasms are formed from the same type of tissue they come from. Malignant ...
into account before rendering a diagnosis. When looking at possible diagnoses several came into consideration but were later ruled out. These include: schizophrenia, schizophreniform, delusional disorder, delirium, peduncular hallucinosis, cerebral neoplasms, and temporal lobe focus epilepsy. Treatments for these diagnoses include the implementation of medications in order to treat the positive symptoms that Joan of Arc experienced. Also therapy would be considered in order to focus on social and learning
research of this fatal disease. Cancer is the most aggressive disease of a larger class known as neoplasms. Neoplasms do not fully comply with the parts of the cell that control the growth and functions of the cell. These cells eventually become abnormal growths and can be recognized as not normal tissue. These traits are passed down as the cell reproduces therefore spreading the cancer. Neoplasms are generally classified into two groups: malignant and benign. Malignant tumors, or abnormal tissue
to keep the cells happy and help to maintain homeostasis. There are many carcinogens that cause cancer leading to the lungs not to doing their job. Sometimes the cancer spreads and causes metastases. The patient’s medical diagnosis is malignant neoplasm of the bronchus and lung brain metastases. The lungs are two large sacs within the human body that optimize gas exchange between the air breathed and the blood. (Lung cancer, 2013) The lungs take in oxygen and release carbon dioxide. The lungs are
The Spanish lynx is indigenous to Spain. They almost went extinct with the population dropping below 100 in 2002. The Iberian wolf is a carnivore. They have a bad reputation because they kill hundred of people each year. Farmers and the Wolves have tension because the wolves eat their crops. Long haired mountain goat are easy to find in the mountains of Spain. There are about 20,000 in Spain. They like to eat grass, herbs, shrubs, lichens and mosses The Spanish black vulture is the
Acute Myeloid Leukemia (AML) is the most common type of acute leukemia in adults. AML is a heterogeneous disease which results from genetic alterations in normal hematopoietic stem cells. These alterations induce differentiation arrest and/or excessive proliferation of abnormal leukemic cells or blasts [1]. Recent genomic studies have identified that recurrent somatic mutations in patients with AML blocks differentiation and/or enhance self-renewal by altered transcription factors [2,3]. The genetic
malignant neoplasm and humans. My immediate reaction after reading this thesis was to reject a proposal that so debased the human race and exacted such a harsh blow to every human's ego. Upon further consideration, however, Hern's reasoning becomes less blatantly offensive and more plausible. Although his argument and its correlating implications contain some contradictions, his overall points appear regrettably compelling and difficult to refute. By medical definition, a malignant neoplasm is diagnosed
Neuroblastoma is one of the third most common of childhood cancers. There are about six hundred and fifty cases a year in the United States or about six percent of childhood cancers. It often is diagnosed in infancy and rarely in children who have reached the age of ten. Neuroblastoma is an adrenal cancer that most often develops in the adrenal glands atop of the kidneys of a fetus or in infants. Neuroblastoma can also develop anywhere along the sympathetic nervous system chain from the neck to
