Pernicious Anemia and its association to orthostatic hypertension Pernicious anemia is the major form of vitamin B12 deficiency. It is caused by serum antibodies against intrinsic factor which leads to B12 deficiency rather than by B12 deficiency itself. Absorption of vitamin B12 requires intrinsic factor which is secreted by parietal cells. Pernicious anemia is marked by autoimmune attack on gastric mucosa and a loss in parietal cells. Approximately 75% of the affected patients have type I antibody

A controversial topic of discussion‚ evolution can invoke heated debate between individuals of a theistic background and persons of an atheistic approach. Those with a religious background tend to have a belief that God created the world and all the creatures upon the earth‚ and achieved this feat in the span of a few days. Cataclysms occur and biological changes happen due to a divine influence. Conversely‚ the non-religious view evolution as a scientific fact‚ and believe that natural selection

Pathophysiology J. Dobrzyn May 31‚ 2013 Hodgkin ’s Disease In 1832 Thomas Hodgkin described a progressively fatal condition characterized by enormous lymph node swelling that he believed to be one disease. Characteristic cells involved in this disease were identified microscopically by Sternberg and Reed in 1898 and 1902‚ respectively. The identification of these cells‚ now known as Reed-Sternberg cells‚ allowed for the initial classification of Hodgkin ’s disease. In the past two decades advances in histology

Heart Disease and Stroke Essay Every year‚ 17.1 million lives are taken away due to tobacco use‚ an unhealthy diet‚ and physical inactivity. Factors which lead all lead to cardiovascular diseases‚ the world’s largest killer. Cardiovascular diseases affect all ages and gender; however‚ it is more perceptible in low and middle income countries‚ where more than 80% off cardiovascular related deaths occur. By the year 2030‚ approximately 23.6 million people will parish due to cardiovascular diseases

Infectious Disease – an illness due to specific infections agents or its toxic products that arises through transmission from an infected person‚ animal ‚or reservoir to a susceptible host‚ either directly or indirectly through an intermediate plant or animal host .

The four forces of evolution include mutation‚ gene flow‚ genetic drift‚ and natural selection. Mutation is when there is a change occurs in a gene or chromosome structure which results in a difference in a physical or behavior trait. This trait can be carried into the next generation because the trait is contained in the gene. Gene flow is the process of genes transferring from one population to another. Genes can be transferred to different populations by migration of individuals along with the

Evolution of Life The earth is about 4.54 billion years old and it is evolving throughout its lifetime from a place with volcanoes‚ serve thunderstorms and limited oxygen. The beginning of the life of earth is occurred due to a process that has set a sequence most practical events towards the foundation of where life actually formed so many years ago. The chemical evolution practical process created inorganic molecules to form organic molecules. Slowly this process of evolution created the foundation

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane. The cell is the very smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms‚ which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant

Cell Respiration Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose‚ which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy‚ but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity‚ the chemical processes of respiration convert the energy in glucose into usable form. Adenosine
