Insulin Dependent Diabetes Mellitus Gestational Diabetes
1,238 wordsDiabetes mellitus is a group of diseases characterized by high levels of blood glucose resulting from defects in insulin secretion, insulin action, or both. Diabetes can be associated with serious complications and premature death, but persons with diabetes can take measures to reduce the likelihood of such occurrences. 15. 7 million people -- 5. 9 % of the population -- have diabetes. But only 10. 3 million people are diagnosed so that leaves 5. 4 million people not diagnosed. Studies have foun...

Mao Inhibitors Gastrointestinal Tract
1,358 wordsComparison Between Mechanism of Action and Pharmacodynamics of Dothiepin and Fluoxetine Mechanism of action and pharmacodynamic's Dothiepin is a tricyclic antidepressant. It acts by promoting the effectiveness of several amines (dopamine, norepinephrine, and 5 -hydroxytryptamine, which is also known as 5 HT and serotonin). It functions by inhibiting their reuptake at the terminals of nerve cells, thus leading to their prolonged presence at the synaptic cleft and an increased effect on the neuron...

Red Blood Cells Connective Tissue
986 wordsfunctions in the rapid internal transport of substances Your body's differentiated cells, which perform specialized tasks, cannot fend for themselves. Different types must interact in coordinated ways to maintain the composition, volume, and temperature of a tissue fluid surrounding them, the interstitial fluid. A circulating connective tissue-blood-interacts with tissue fluid, making continual deliveries and pickups that help keep conditions tolerable for enzymes and other molecules heart, gene...

Back To Earth Solar Wind
1,313 wordsn this ERA of tight space budgets and infrequent deep-space missions, solar system researchers have pushed to squeeze more science from existing interplanetary spacecraft. By drastically altering their orbital paths using gravity-assisted maneuvers combined with relatively brief rocket firings, veteran probes can be sent on productive extended missions. This technique was successfully employed by the International Sun-Earth Explorer 3 (ISSE 3) spacecraft to accomplish two important space firsts:...

Mycobacterium Tuberculosis Rheumatoid Arthritis
1,983 wordsInflammation is the bodies normal response to injured tissues, although it can sometimes lead to further tissue damage. It was first described around 30 BC by Celsius, as tumour (swelling), rumor (redness), calor (heat) and door (pain); although excess secretion and loss of function are now commonly added. Inflammation is a response which has evolved to try and put things right in a damaged tissue, for example the pain and loss of function allow the tissue to heal easier whilst the heat and redn...

Excess Dietary Protein And Calcium
1,202 words... sodium in the water surrounding it. Ninety-nine percent of the calcium is in bone. Bone responds to acid by chemical reactions with the rapid release of carbonate, citrate, and sodium from the hydration shell (Barzel 1051). Therefore, in response to chronic acid stress such as an acid-ash diet, cellular responses mobilize bone and calcium as a buffer. As the result, more calcium will be reserved from bone, and excreted in urine. The effects can be mild in temporary cases, such as hypercalciu...

Plasma Membrane Permeable Membrane
777 wordsThe plasma membrane is the boundary of life; this selectively permeable membrane allows the cell to maintain a unique internal environment and to control the movement of materials into and out of the cell. The phospholipid bilayer (fluid music model) with specific membrane proteins accounts for he selective permeability of the membrane and passive and active transport mechanisms. Membrane phospholipids are amphipathic. Cell membranes are phospholipid bilayers with the hydrophobic hydrocarbon tai...

Plasma Membrane Passive Transport
834 wordsBeing one of the most important components of a cell, the plasma membrane, or cell membrane plays a huge role in regulating how things get in and out of cells. The plasma membranes unique structure enables it to let only certain molecules pass through the cell. This ability is called selective permeability. Most of the plasma membrane in most cells is made up of a phospholipid bilayer with proteins either embedded into it or sticking out from either side of the membrane. The heads of the phospho...

Factor Viii Clotting Factor
1,200 words... ecombinant DNA technology and the discovery of the genes that control production of factor VIII have led to the development of recombinant factor concentrates that do not rely on plasma at all. What is the Cause of Hemophilia? Hemophilia occurs when one of the factors needed for blood to clot is missing or the amount present is too low for normal clotting to occur. Factor VIII is missing or too low in about 90 % of hemophilia cases. Factor IX is deficient in about 9 % of cases. Factor XI, X,...

All of these were highly effective in treating the positive symptoms of schizophrenia but not as effective for treating the negative symptoms. As well, these drugs were well known for the side effects that they produced such as dizziness, muscle stiffness...

Control Of Blood Glucose Levels
1,253 wordsControl of Blood Glucose Levels Homeostasis is the mechanism for keeping your internal conditions constant. Homeostatic control of blood glucose can be made using insulin. It decreases blood sugar concentration making it about 80 - 120 mg of glucose per 100 ml of blood during fasting Insulin is the only hormone that decreases blood sugar level. The presence of insulin causes a cells membrane to be more permeable to glucose; this causes blood sugar level to drop in the blood. Homeostatic control ...

Factor Viii Clotting Factor
2,041 wordsHemophilia is a genetic bleeding disorder. People who have hemophilia have a deficiency or an absence of a coagulation protein. A blood clotting factor is deficient or absent. Bleeding is most often into joints, such as the knee, elbow, or ankle, but bleeding can occur anywhere in the body. People with hemophilia bleed longer, not faster. The severity of hemophilia varies greatly. Hemophilia A and Hemophilia B are the most common genetic bleeding disorders. Hemophilia A is observed in 80 percent...

Back And Forth Stimulated Emission
1,080 wordsThe light from lasers differs from ordinary light in several important aspects. Ordinary light from a light bulb travels randomly in all directions (unless the bulb is equipped with an integral reflector that directs the light). The light is thus incoherent. Even when incoherent light is directed with a reflector, it still spreads rapidly. The light from a laser is temporary and spatially coherent. This means that all of the wave-fronts of light are lined up in time and space (see Diagrams). The...
