The Analysis of Lipids Determination of Fat by Soxhlet Extraction

...Food Chemistry Laboratory report The analysis of Lipids Determination of fat by Soxhlet Extraction and Determination of fat content in milk by Gerber method Introduction Lipids are molecular organic compounds, composed largely of carbon, oxygen and hydrogen and are essential for cell growth. Lipids are non-soluble in water and combine with carbohydrates and proteins to form the majority of all plant and animal cells. Lipids are transported through the body attached to protein and are an important element of food. Lipids are the third major micronutrient required for the body after carbohydrates and protein. Lipids are also a medical term for ‘fat’ and though all fats are lipids, not all lipids are fats. Lipids have many roles within the body, one of its main duties is to transport, absorb and digest the fat soluble vitamins A,D,E and K. They provide the most energy to the body, are used for energy storage, cell membrane development, and they protect vital organs. Other major purposes are that they insulate layers under the skin, provide vitamins, essential nutrients and fatty acids in the body. Fatty acids cannot be made by the body and are therefore fat is essential in the diet. In many foods the lipid components add to flavor perception, texture, mouth feel and appearance. (Intro to food Nutrition handout, 15/02/11) It is important to remember that although fat is essential, the body only requires 30% of daily calorie intake to come from fat.

Statins Use

...In no more than 1-2 paragraphs discuss the major differences (controversies) between the new ACC/AHA’s Guidelines on the treatment of cholesterol and the “old” lipid guidelines known as ATP III (Adult treatment plan III). What are your thoughs on these changes? Lipid management over the last decade has been utilizing guidelines from the 3rd report of the National Cholesterol Education Program. In November 2013 new guidelines were established with controversy regarding some of the changes that were to be made. The 2013 AHA/ACC lipid guidelines provide a new method to the management of hyperlipidemia, which differs from the ATP-III guidelines. The new guidelines created differ in that it includes the change from treating target levels or lab tests to treatment based on risk level and intensity of statin therapy. They identified 4 groups that would likely benefit from statin therapy: * History of arteriosclerotic cardiovascular disease (ASCVD) * LDL- cholesterol >190 mg/dl * Between 40-75 years of age with history of diabetes * Between 40-75 year of age and a 10-year ASVD Risk > 7.5% A second key difference is lack of LDL goals in order to monitor the effectiveness of cholesterol lowering medications. There were no recommendations made on follow up LDL testing, which differs from previous guidelines. The best way to accomplish the AHA/ACC recommended goals is to focus on decreasing cardiovascular disease events or ASCVD. Another major change to the guidelines...

...it. The hypolipidemic activity was analysed by reading the blood serum level in UV at 505 nm after treated with reagent present in auto span diagnostic kit. Dose of Methanolic extracts of QI had been prepared by using distilled water i.e. 200 mg/kg p.o. Methanolic extracts of QI significantly reduce the harmful lipid layer in blood serum at varying concentration and dose dependent manner which shows that the plant carries the hypolipidemic properties. It reduces the LDL, VLDL, cholesterol, triglyceride and raise HDL level in blood serum upto certain extent which was may be due to the inhibition of lipid peroxidation as the plants contain some active ingredients acting as antioxidants. Our result shows that the plants extracts recover the disorders in lipid metabolism noted in hyperlipidemic state.

Mr. Galore

...Mr. Galore was ordered by his doctor to take actions to reduce his blood pressure. Some of these actions include taking Lisinopril, having blood work done to check metabolic processes and cholesterol levels, to go on a cardiac diet with lower sodium, and to have a chest x-ray done to check his lung and heart status. To accomplish this, several members of the interdisciplinary team will need to be involved. To begin with, Mr. Galore was ordered by his doctor to take Lisinopril. So, the doctor automatically comes into play, because he is the one that makes this determination. Then, the charge nurse and the pharmacy come into the picture. In order for him to receive this medication, it will have to be ordered through the pharmacy. The charge nurse can order this medication and the pharmacy will have it delivered. Then, the nurse can administer this medication to the patient. If Mr. Galore has any questions or is visited by his friends, the unit secretary can help out in answering some of his questions or in directing his friends to the room where he is located. The next day, Mr. Galore is required to have blood work done. To do this, the patient care technician is needed to perform the procedure. After, the blood must be sent to the lab for further analysis. The lab technician is the important member here that will analyze the blood sample.

Atherosclerosis Research Paper

...Introduction: Atherosclerosis is defined as the hardening or narrowing of the arteries. This is caused by the formation of plaque within arteries, a fatty substance composed of cholesterol, calcium, and fibrin [1]. The formation of plaque within arteries restricts the blood flow through the arteries and to the rest of the body. When excess plaque is built up, a blood clot, or thrombus, may form on the surface or a piece of the plaque may fall off freely into the blood stream. In either case, a heart attack or stroke is likely to occur which are two of the leading causes of morbidity and mortality in today’s world [7]. Atherosclerosis is known to be a chronic and progressive inflammatory disease that may begin development even in early...
