Ovarian Cancer What is Ovarian Cancer? Ovarian cancer is the abnormal growth of malignant cells in the ovaries, the egg (ovum) producing part of the female reproductive system. Often, Ovarian cancer goes undetected until it has metastasized (spread) to the pelvis and abdomen. At this late stage, this cancer is difficult to treat. Ovarian Cancer ranks as the 11th most common cancer among women, and it is the 5th leading cause of cancer-related death for women. What different types of ovarian cancers
pertains to the category of germ cell tumors. Even so, teratomas are most commonly found in certain organs, such as the brain, thyroid, liver, lungs, ovaries, and testes. Subsequently, teratomas are believed to be caused by the abnormal development or migration of either germ cells or embryonic (stem) cells during embryogenesis. If the teratoma is of germ cell origin, then it will be located in either the testes or ovaries. However, if it is derived from embryonic cells, then it can be located anywhere
Some call it “horror'; and some call it “the super germ';, but now, our always known “regular'; bacteria, those one-celled creatures once considered under control with antibiotics, have invaded our hospitals and headlines with a vengeance. The vengeance used against us is caused by an existing organism called necrotizing fasciitis, the so-called flesh-eating bacteria, caused by Group A streptococcus. What this organism does is progressively destroy the human body tissue all the
Medical Model' is also linked with the mechanistic model, where illness is seen as a nuisance and causes the 'machine' to break down and even stop working completely. Through Helman's study we can see that although we know how we catch a cold i.e. germs, lay perceptions still exist despite the Bio Medical model. Helman's study demonstrates that variations of health still exist within our society. Two types of illnesses related to this are chronic illness (lasting/terminal) and acute illness
Guns, Germs and Steel Jared Diamond, author of the Pulitzer Prize Winning, National Best Selling book Guns, Germs and Steel, summarizes his book by saying the following: "History followed different courses for different peoples because of differences among peoples' environments, not because of biological differences among peoples themselves." Guns, Germs and Steel is historical literature that documents Jared Diamond's views on how the world as we know it developed. However, is his thesis that environmental
Antibacterial Soap Dial antibacterial soap advertises that it is "over 10x more effective at killing disease-causing germs than ordinary liquid hand soaps"(1). To the average consumer a soap with the ability to kill more germs seems to be more effective. But is a more powerful antibacterial soap always better? Various studies suggest that antibacterial soaps can be harmful and may lead to problems like super bugs, dry skin, and hand eczema. According to current research antibacterial soaps are
This essay will introduce some similarities and differences between both symptoms and experiences of six different authors who have been personally affected by obsessive-compulsive disorder (OCD). Since OCD is not very well understood by many members of the public ("Escape"), I hope that the experiences of the authors that I researched will be able to paint a vivid picture of what life with OCD is like. Obsessive-compulsive disorder involves a chemical imbalance in the brain. This chemical imbalance
bacterium. TB is spread through the air by carriers of the germ. People who breathe the same air can become infected with the TB germ. People who do work around or with people with the TB disease should take medicine. TB infection means that the person has the TB germs but they are in an inactive state. When TB germs enter the body, the immune system builds a wall around them. While TB germs are inactive, they cannot cause any damage. These germs can stay alive for many years in these walls and eventually
at her. She told my like an innocent girl that it was sticking in a tree on the way home from school. I really didn't care about where she got it from I just wanted that disgusting piece of trash out of her mouth immediately before she caught some germs. I told Scout to spit it out immediately. She was actually pretty obedient and spit the gum out. She told me that she had been chewing it all afternoon and that if she wasn't dead and didn't feel sick. She was obviously mad at me for ruining her chewing
In Praise of Jared Diamond's Guns, Germs, and Steel Jared Diamond's bestseller Guns, Germs, and Steel (GG&S) is an attempt to explain why some parts of the world are currently powerful and prosperous while others are poor. Diamond is both a physiologist and a linguist who spends a good deal of his time living with hunter gathers in Papua New Guinea. As a researcher and as a human being, he is convinced that all people have the same potential. Hunter gatherers are just as intelligent, resourceful
most important phases in the life of multicellular organisms. Blastula, a single layered cell structure converts into trilaminar structure with three layers, known as gastrula. The word ‘gastrula’ means stomach, since stomach (archenteron) is the first thing formed during gastrulation. There are basically three main events that occur during gastrulation. These are as follows; 1. Formation of three primary germ layers. 2. Basic body plan and body axes are established. Three embryonic axes are formed
amazingly complex network of cells, a newborn infant. Through cellular differentiation and growth, this process is completed with precision time and time again, but very rarely a mistake in the "blueprint" of growth and development does occur. Following is a description of how the pathways of this intricate web are followed and the mistakes which happen when they are not. The impressive process of differentiation changes a single-cell into a complicated system of cells as distinct as bold and bone
brands, of bread. In this case, I have chosen two, Sunbeam White, and Brownberry 100% Whole Grain. All bread products, except for gluten free, start with wheat kernel. Boyle and Roth explain, “The wheat kernel (a whole grain) has four main parts.” The germ, endosperm, bran, and husk (chaff). Boyle and Roth also point out that when our ancestors first started milling wheat, they would grind it between two different stones. As technology developed, we had access to separate wheat grain and remove parts
Order Monotremata: The defenition of a monotreme is an unusual mammal that lays eggs instead of giving birth to live babies. A few examples are the echidna and the platypus. Their skulls have certain features that resemble reptiles. They have three bodily systems, they have the digestive system, urinary system, and reproductive system. These systems all end up in the same chamber for monotremes called the cloaca. Cloaca means “one hole’’ so it fits perfectly with the monotremes situation. After
September 28, 1895. Louis Pasteur significantly impacted the world through his description of the process of fermentation, his research proving the germ theory of disease, and his findings in the field of immunology. Before his invention of germ theory, Louis Pasteur proved the widely unpopular hypothesis that fermentation was caused by living cells. While still in school, he completed research in the optical activity
Unit 5.3 Task 1 The germ theory of disease is the theory that microscopic organisms such as bacteria and viruses can cause infectious diseases. The theory was confirmed by Louis Pasteur in the 1800’s. Once germ theory was discovered it started the development of sanitation and aseptic techniques. Also due to Louis Pasteur’s work with fermentation and broths he developed pasteurization for beverages such as milk and wine. Before the germ cell theory was proposed in any form people believed in
The Contributions Made by Louis Pasture, Florence Nightingale and James Simpson to Medical Science James young who was professor of midwifery at Edinburgh University, experimented on himself and his assistants to find a more effective anaesthetic than ether which had been developed in the USA but had been found to cause a nasty cough to patients. In 1847 he tested chloroform and found it to be a much less potent substance than ether. He reported his discoveries, but without a proper system
Encyclopedia Britannica lists a number of elements of the microscopic world that Leeuwenhoek was among the first to accurately describe, including spermatozoa, striations in muscle tissue, mouthparts of insects, fine structures in plants, and red blood cells. Arguably the most important contributions Leeuwenhoek made to the field of science were those that directly contested the long-standing theory of spontaneous generation. Using his own techniques, the details of which are a mystery to this very day
human organism through Germline Gene Therapy. Right now it is acceptable to use to gain a better understanding of how DNA and genes work, but it should never surpass that. “Any mistake you make on a germ line is passed to future generations, and may affect thousands of people. The people affected by germ-line gene therapy - children, and future descendants, did not agree or consent to the treatment. You are tampering with nature and playing God. When gene therapy goes wrong, it could lead to horrific
Mold can cause illness such as vomiting or feeling nauseated when it is eaten or when it smells bad. Bacteria are single celled microbes. Bacteria reproduce by binary fission. In this process, the bacterium, which is a single cell, divides into two identical daughter cells. Binary
