...Kathleen Cumba, 3230784 Clostridium difficile There are millions of different varieties of bacteria currently living in your body that cause no harm called your normal flora. These bacteria prevent infection from other bacteria that do not belong there through means of competition. Clostridium difficile is an infectious sporulating bacteria that develops your gut, causing severe abdominal pains and frequent diarrhea. This microorganism was initially isolated from a newborn’s fecal matter in 1935 by Hall and O’Toole, but the studies weren't published until 19783(Heinlen, L.2010). Bacteria constantly have to go through adaptations to their environment, find other means to live if it currently doesn't fulfill their needs for expansion or growth. In medium for the bacteria C.difficile at the least there would be two optimal nutrients required: amino acids and vitamins5(Karasawa T.). There are many different strains of C.difficile and many mutations can occur within the bacterium, for example Isolates of PCR-027 strain type of C.difficile started to present resistance to fluoroquinolone unlike previous isolates before 20018(Spigaglia, P. 2010). Test like PCR and sequencing were preformed to determine what mutations had occurred for this resistance to happen. The results found were mutations occurring in the active site in the DNA causing a mutation in gyrA gene effecting the resistance. Not only do mutations, multiple strains, and resistance make it difficult to control the bacteria...

...the patient (4). Fecal transplantation involves the introduction of gut bacteria from healthy donor into patient and this method should rebalance the body system (5). The process of reintroduced gut bacteria is efficient as it can highly reduce the recurrence of CDI. Researchers found out that fecal transplantation have cure rate of almost 90% and only 15% of recurrence rate (6). In addition, administration of probiotic is also the other method. Probiotics are live bacteria and yeasts that benefit our health. Researchers have proposed that probiotics may maintain the flora of the gut or competitively inhibit the growth of pathogens (7). However, there are no strong evidences to support that probiotics are effective to cure CDI. Further research has to be conducted to give public reliable information. ...

...Dehydration Effects Dehydration is the “excessive loss of water resulting in depletion of body fluids” (Grosvenor & Smolin, 2006, p. 282). When the body goes through dehydration there can be many symptoms. Some of these symptoms can include: feelings of nausea, light-headedness, and feeling dizzy. Dehydration can cause symptoms to show more rapidly than any other vitamin deficiency. With other vitamin deficiencies, days or weeks can pass before symptoms are felt by the body (Grosvenor & Smolin, 2006). Symptoms can be seen when dehydrated after only an hour of activity on a hot day. Water is essential to health maintenance because the human body is more than half water. The typical adult’s body weight is about 60% water. This number is even higher in small children and infants. When dehydration sets in, it is important to replace this lost water as fast as possible. Another reason that water is essential to health maintenance is that the body needs a certain proportion of water and dissolved substances. This proportion of water and dissolved substances is necessary so that all the chemical reactions necessary to sustain life continue to function (Grosvenor & Smolin, 2006). Water has many functions in the body. Muscles are made up of almost 75% water while bones are about 25% water. Water is used as a fluid both inside and outside the cells in a body. Water found in the cells is known as intracellular fluid while water outside the cells is known as extracellular...

...Lung cancer arises from the epithelial of the respiratory track. Lung cancer is the most severe cancer compare to the other cases of cancer. Lung cancer is the number one killer in United States and the world. In this country alone, there are 219440 new cases yearly and 159390 death yearly which is almost 57% of death yearly form lung cancer. These cases of lung cancer account for 14% of all cancer in men and 15% in women every year. (McCance, Huether, Brashers, & Rote, 2010, p. 1299). Although tobacco smoking is the number causes of lung cancer, there are some new cases of lung cancer arising every year without any cause. Cigarette smoking accounts for almost 90% of all lung cancer (http://www.cdc.gov/cancer/lung/basic_info/index.htm) . Other causes of lung cancer can include radon, asbestos, second hand smoking, family history, diet and air pollution. Lung cancer arises from a single changed epithelial cell in the tracheobronchial airways. A carcinogen from cigarette smoke or other predisposing factor like inherited gene bind to a cell DNA and damages it thereby resulting in multiple genetic abnormalities in bronchial cell which include deletion of chromosomes, activation of oncogenes and inactivation of tumor suppressing genes. This damage results in cellular changes, abnormal cell growth and eventually a malignant cell. The DNA undergoes further changes and becomes unstable as the DNA is passed to daughter’s cell. With the accumulation of genetic changes, the pulmonary epithelium...

...I was unable to follow a low sodium diet for this exercise because I suffer from postural orthostatic tachycardia syndrome, and was instructed by my cardiologist to increase salt intake in order to raise my blood pressure. I also do not know anyone who has to be on a special diet, because all of my family members and friends are healthy and I do not really know anyone who has to be on any dietary restrictions. In order to complete this exercise I did a research on low sodium diet and what effects it has on a human body. Sodium is a mineral which is necessary in order to keep normal fluid balance in our body (Cleveland Clinic). Low sodium diet is considered to be a maximum 2g of salt intake per day. I imagine, as with any other diet, it is hard to follow any strict diet that limits us to take certain amount of anything. For those who are instructed to be on a low sodium diet, it must be very difficult to figure out how much salt is in certain foods. This is especially hard to figure out in processed foods. Even though they are labeled, we discussed serving sizes at the beginning of the semester and how manufacturers can be misleading, so people have a hard time figuring out how many serving of food they are actually eating. In order to stay on this diet people should avoid certain foods which are high in sodium, and the mail source of sodium is table salt that we use in everyday cooking. According to UCSF Medical Center (2014),” The average American eats five or more teaspoons...

...Dehydration Keyva Strickland February 18, 2012 Arnetra Gilliam Dehydration can happen for various reasons. Dehydration happens when there is a loss of a significant amount of water in your body. To prevent dehydration, you should make sure you have a significant amount of water in your body. Feeling nausea, dizzy or light headed after or during exercise on a hot and summer day is a sign of dehydration. If someone feels they are dehydrated he or she needs to make sure they are drinking plenty of water, Gatorade, Pedialyte (for children), or popsicles. An important fact to remember is that over half of your body weight is water, so water consumption is very important to avoid dehydration and other illnesses. People can live for years without shelter, months without food, but without water they can only live for days. That shows how important water is to your body and life. Water, next to oxygen is the most important component to sustaining a healthy life. Water is needed by our body’s cells, tissues, muscles and system organs; without water, there will be no life. Water is not a nutrient but is considered an important nutrient and is highly needed to maintain life. The most important role of water is that it is a major component in our blood, and it is important in maintaining body temperature along with the elimination of body waste. Water is required in digestion and metabolism and its function is in the regulation of your body temperature. Besides water serving...

Background Research: Ice is frozen water. The state of matter ice is at in room temperature is liquid. When the temperature of water comes below a certain point, called the freezing point, it starts to solidify. The freezing point of pure water is 32 degrees Fahrenheit, but when water comes into contact with different substances the freezing point can sometimes move up or down. Salt is a white crystalline substance that gives seawater its characteristic taste. The chemical formula for table salt is sodium chloride. Salt has many uses in day to day life, and is used as a preservative, seasoning, and as a preventative measure for icing over on bridges. The reason for it being used to prevent ice forming on bridges is that it lowers the freezing point of water to slightly below 0 degrees. What is supposed to happen in this experiment is that the salt, thrown in a thin layer on top of the ice cube, should lower the melting point of the ice and melt a thin layer. The water should then cool down a bit further...

...Clinical Case Study Summary of Hyponatremia The drug MDMA, 3,4-methylenedioxymethamphetamin, commonly known as ecstasy leads to feelings of euphoria, emotional empathy, and increased energy. Hyponatremia is an electrolyte disturbance in which the sodium ion concentration in the plasma is lower than normal. Sodium is the dominant extracellular cation (positive ion) and cannot freely cross from the interstitial space into the cell, because charged sodium ions attract up to 25 water molecules around them, creating a large polar structure that is too large to pass through the cell membrane. In this study we looked at the case of one young college student who passed away from using ecstasy, as well as two other different examples from a marathon runner and a post surgical patient. One of the most serious medical complications of ecstasy abuse is related to symptomatic hyponatremia. The cause of hyponatremia seen with ecstasy is dilutional in nature and likely due to several interacting effects. Excessive water intake has been directly associated with ecstasy use. For partygoers the effects of amphetamines induce dry mouth and the sensation of thirst causing the user to over hydrate especially after a long night of dancing. For marathon runners, excess antidiuretic hormone (ADH, also known as vasopressin) can be released from the result of strenuous physical activity. The treatment of hyponatremia depends on the underlying cause and whether the patient's blood volume status is hypervolemic...

...10/07/2013 Experiment 5: Wittig Reaction Purpose The purpose of this experiment is to synthesize trans-9-(2-phenylethenyl) anthracene using a wittig reagent formed by reacting phosphonium chloride with base. Experimental In a reaction tube, (0.200g) benzyltriphenyl phosphonium chloride, (0.115g) anthraaldehyde, and (.6ml) dichloromethane (DCM) is mixed together with a stir bar. We stirred the mixture rapidly and added (0.26ml) of a 50% NaOH solution dropwise. The mixture was stirred for 20-30 minutes. We added (1.5ml) DCM and (1.5ml) water, and the tube was shaken until the layers separated. The water layer was removed. This step was repeated and the water was removed again. CaCl2 pellets were added to DCM solution until it longer clumped. The solution was filtered to separted the CaCl2 pellets from DCM. DCM was used to wash pellets before filtering. To the solid in bottom of flask, (3ml) of propanol was added, heated and cooled. Filteration was tried once more to gain crystals. Due to nonexistent crystals a melting point could not be performed. Observations: We noticed after adding propanol our solution became very orange and cloudy. After heating it the solution was a clear golden color. We chilled the solution in ice and attained no crystals. After repeatedly heating and cooling, we saw our solution go from cloudy to clear over and over. After filtering one more time the color of orange stained the filter paper...

...1 Dehydration Mike Martin SCI/241 01/21/2012 Mike Esposito 2 Water is important for creating and sustaining life. In humans, the body is made up of about sixty percent water. Every part of our body including muscle, bone, and blood consists of some percentage of water. About a third of our total body water is extracellular fluid, which is fluid outside and between cells and water in our blood. This is the most important as the blood in our bodies delivers the oxygen and nutrients to all cells. Without the proper amount of water everyday there is a risk of dehydration. Severe dehydration can cause nerve damage, seizures, abnormal blood pressure, brain damage, arrhythmia, and even death. Water is essential to everyday health maintenance as it helps in the balance of our body fluids, such as absorption, digestion, circulation, and distribution of nutrients. The muscles, which are about seventy-five percent water, need that balance of fluids to perform properly. This is especially true when exercising, or running. Body temperature is also regulated with the help of water, since water changes temperature slowly. Water also helps the body get rid of toxins through the kidneys. Without enough fluids the kidneys will keep extra fluids instead of passing them through urine. Water also helps pass food through the intestines, which in turn prevents constipation. 3 Every function in our bodies runs smoothly and works properly with an adequate supply of water. This could...
