Diabetes :: essays research papers

DIABETES In 1921, Canadian researchers isolated insulin from dog pancreases and discovered that the hormone is essential to controlling blood sugar. Given by injection, insulin reversed wasting in diabetic children and extended their lives. Dramatic as its effects are, however, insulin isn't a cure for diabetes. People with the disorder must monitor their blood sugar closely and take insulin injections to reduce the risk of nerve damage and heart, kidney, and eye disease. In a small percentage of these people, insulin injections fail to keep blood-sugar concentrations from fluctuating wildly. Scientists and patients agree that the ideal diabetes treatment would control patients' blood-sugar concentrations without requiring them to take insulin. One long-sought option is transplantation of pancreatic cell clusters, called islets, that make insulin. Though the approach is simple, it has succeeded in only a small fraction of the attempts. This year, however, a Canadian team announced 11 consecutive successes--islet transplants that permitted the recipients to stop taking insulin. Although there are still questions about the long-term safety and efficacy of this treatment, there's a sense of excitement among researchers. In Toronto at the June meeting of the Endocrine Society, David M. Harlan of the National Institutes of Health in Bethesda noted, "Islet-cell transplantation, which has long been promising, appears poised to fulfill its promise." Affecting 1 million people in the United States, type I diabetes arises when a patient's immune system attacks the insulin-producing cells in the pancreas. While a pancreas transplant effectively cures the diabetes in most cases, the procedure is difficult and expensive and few donor pancreases are available. Physicians can transplant just the insulin-producing cells in a less taxing process that doesn't require major surgery. For the past 25 years, they've tested procedures in which they inject the cells into the major blood vessel flowing to the liver. The cells can take up residence there. After the procedure, patients must take immunosuppressive drugs. Overall, just 8 percent of people given islet-cell transplants have improved their ability to control blood-sugar concentration enough to stop taking insulin. They concerns and problems that they have been dealing with in the past are those of the transplant wiping out your immune system or even blowing your diabetes out of proportion and making the diabetic very sick. The case with the immune system wiping out would have the same similarities as someone with the disease, AIDS. This is the first study that allows the diabetic the ability to not be on insulin and not have to take pills to help the immune system.

Intel vs AMD Processors Essay

In an age where technology is constantly evolving and the demand for performance is increasing, the central processing unit (CPU), also known as the processor, is a main concern for many computer buyers. There are many considerations that take place when choosing a processor such as whether the computer will be used for storage or gaming, will the user be looking for performance in speed or graphics, and individual budget. Among all the different brands the two biggest companies considered competitors are Intel and AMD. Even though each company may have an edge in certain areas, both companies continue to constantly make changes and improvements to their products in an attempt to remain competitive. The purpose of this comparative paper is to look at both companies to determine if one company’s processor is truly better than the other. Literature Review Performance and value are major considerations when deciding to purchase a new computer. Much of a computers performance is based on the central processing unit also known as the CPU or processor. According to Fisher, â€Å"The CPU could be considered the â€Å"brains† of the computer†¦and is responsible for interpreting and executing most of the commands from the computer’s hardware and software. † In today’s market the two leaders in CPU production are Intel and Advanced Micro Device, Inc (AMD). Depending on a person’s computing needs, one CPU might be better than the other when considering price, speed, and performance. Analyzing each companies product and comparing them will help use determine which processor is best for us. Our first consideration will be speed. If speed is a big concern, which it is for many computer gamers, Intel has shown to be the better product. According to Singh, â€Å"Intel processors give you a higher clocking speed, which means they have a higher frequency of work done per second. † Intel is designed different from AMD because it divides the total work into the smallest possible division and then goes through it in a high frequency. AMD goes through it process at a slower rate but processes more of its data per cycle. For this reason, one can not make the assumption that Intel is better simply because it is the faster processor. In addition, AMD has recently made claims that there new Piledriver processor will present stiff competition for Intel’s latest Ivy Bridge processor. Another consideration is power consumption. In the past AMD use to be the clear winner, their release of the Athlon 64 surpassed the efficiency of Intel’s Pentium 4 processor. Since then, Intel has implemented new power management features and has focused on increasing efficiency. As a result, Intel has beat out AMD and currently has the most efficient processors available. An added benefit to lower power consumption is that the processor dissipates less heat and stays cooler. AMD has been known for heating up faster under intense and heavy duty computing conditions. However, it is speculated that the new generation of AMD processors have taken care of the overheating issues. Gavrichenkov (2011) conducted a comparison of the power efficiency of AMD and Intel Processor and stated: Systems based on processors with integrated graphics cores become increasingly popular not only due to possible system miniaturization. In most cases the users decide to go with them, for cost-cutting purposes. Processors like that help to save some cash not only by omitting the external graphics accelerator, but also by allowing to build a more energy-efficient system with total power consumption being lower than that of a system with discrete graphics. There is another bonus to it: quiet operation modes, because lower power consumption leads to lower heat dissipation and therefore the use of simpler cooling systems. (p. ) The next consideration is overall performance. Depending on your needs, performance can be interpreted in different ways. If you compare processors with the same rating side by side it is clear that Intel is the better performer. But, if you are a gamer you will discover that AMD is the better choice. AMD processors are much more compatible with ATI graphic cards. To many gamers graphics are everything and when looking for a processor to integrate with an ATI graphics card AMD is the best choice. If you do not intend on using you computer for gaming and simply would like computing performance Intel is the better choice. Intel has the best multitasking abilities which according to Singh, â€Å"is the ability to divide work into smaller pieces for faster computing. † The final and to some the most significant consideration is price. This is an area where AMD and Intel are clearly distinguished. Although performance statistics show the Intel is slightly better overall, AMD is priced 20% to 60% cheaper. For gamers who are generally under the age of 30, this difference in price makes AMD the favorable processor. To those who have the money and are looking for performance Intel would be the better choice. According to Shulka (2012), â€Å" (Intel) prices will be slightly on the higher side compared to AMD, but given the consistency, superior performance specs and its downward- traveling energy consumption curve. Intel many not have that much to worry about. † It retrospective, it ultimately depends on what it is you plan on using your computer for.

Elizabeth Cady Stanton And The Declaration Of Independence...

Overview Principally authored by Elizabeth Cady Stanton and presented in Seneca Falls, New York on July 19, 1848 at the first Women’s Rights Convention, The Declaration of Sentiments outlined a series of grievances resulting from the marginalization of women and proposed eleven resolutions, arguing that women had the right to equality in all aspects of their lives. The Declaration generated widespread ridicule and even hostility particularly from religious leaders and members of the press and even some members of the growing women’s rights movement distanced themselves from the document for its controversial inclusion of a resolution supporting women’s right to vote. Modeled after the Declaration of Independence, Stanton connected the nascent campaign for women’s rights with a well-known American symbol of liberty while underscoring the point that while the Declaration of Independence was all-inclusive, its language specifically excluded women. Stanton presented the Declaration to a crowd of three hundred men and women. The women s declaration detailed specific injustices: their lack of property and divorce rights, their exclusion from public participation in religion and education, and their entire disenfranchisement, including psychological oppression. Stanton’s document was also a call to action, petitioning more women to organize similar conventions throughout the country.
