How important for the prevention of disease was Edward Jenner’s discovery of the smallpox vaccination in 1796? Edward Jenner took the first step in understanding and preventing infectious diseases by developing a smallpox vaccination in the year 1796. This was important as he saved many lives with this new discovery and improved previous methods of preventing disease. Future scientists such as Pasteur and Koch were also able to use Jenner’s work to develop vaccinations for other serious illnesses. However, it was also a limited discovery because it merely tackled one disease and his idea was only gradually accepted by other doctors.
Other than the chance discovery, another factor that held back Fleming was government funding. After Fleming published his results, the government wasn’t interested in developing it because they thought there was no need for it so with no funding, Fleming decided abandon his research. After his discovery it took Florey and Chain another 10 years to read about it and start the research. At this time, WW2 had broke out which deprived the government of a lot of money as many factories and other places were being bombed, hence Florey and Chain also didn’t get any funding from the british government because penicillin required a range of equipment and people which the government couldn’t provide. Penicillin only came to Britain after it had been mass produced in USA which took another 3 years.
With the lack of soldiers, it would be easier to invade Rome, which could’ve led to the decline of the Empire. This proves that internal decay was one of the major causes for the end of Rome. Document 6 shows the invasions of Barbarians in 476 on the Roman Empire. This demonstrates that the government and military were becoming weaker to the point where they weren’t strong enough to protect the empire from invasions. The government could not control all these invasions, so this was another component that helped the fall of the Roman Empire.
In one instance, the parent attacked a human who approached their babies. (fws.gov). The Northern Snakehead has made quite an economic impact on the areas it has invaded. Since it destroys ecosystems, money has to be spent on pesticides to attempt to wipe out the species. When the pesticide is placed in a pond, it kills every fish in that pond.
For example, there were no longer any engineers left who knew how to build or maintain aqueducts. This meant that when these structures broke they couldn’t be fixed, and so over time there was less provision for clean water. The local population used the stone from the bath houses and other structures to build their own homes as there was less emphasis on public health. The new rulers of Britain did not think it was as important as the Romans had. By 1350 there were some quite serious public health problems in towns, where the lack of fresh water and drainage was a problem which caused the water to be contaminated by other sources and was not healthy to drink.
The population of the natives was lowered to an amount they left them without enough people to sustains their lifestyles, they didn’t have enough people to hunt, gather, and farm, and they didn’t have the elders to keep their traditions and values alive. With the fast spread of disease the natives had almost no choice but to join other tribes for protection and to sustain their way of life to even a small extent. The article also spoke about how the natives had become too reliant on the settlers for trade and had slowly become too twisted into the trade. “Liquor, for example,
Drugs such as opiates and crack cocaine should not be legal due to the massive effects they have on individuals. According to Charles B. Rangel “Drug legalization threatens to undermine our society. The argument about the economic costs associated with the drug war is a selfish argument that coincides with the short-sighted planning that we have been using with other social policies. With any legalization of drugs, related problems would not go away; they would only intensify. If we legalize, we will be paying much more than the $30 billion per year we now spend on direct health care costs associated with illegal drug use.” (Charles B. Rangel; Criminal Justice Ethics, Vol.
Scientists believe this method will transform the severe disease of Duchenne muscular dystrophy to a much milder Becker muscular dystrophy. For me, some pros to this approach would be a cure for a severe case of muscular dystrophy, but it is unfortunate that the patient will still have the disorder, just in a milder form. A con would be any side effects that exon skipping may have. Since there are not any recorded cases of this being done in the United States, it is hard to know whether or not exon skipping could be potentially dangerous to those who want to try the treatment since testing in human patients is still out of the question. Another con is within the administration of the treatment.
N pet owners would want to lose a family member due to a lack of blood, but the pricing of Oxyglobin is highly sensitive looking at Table A. The problem that hinders both of these products is that there is no sense of urgency for blood substitutes in the market. Their high price assumes that they are safer and more effective than traditional donated blood, but that has not been proven. The acceptance of donated blood has also been a barrier of resistance to the blood substitute market, even with the growing knowledge of veterinary blood donors. Marketing of Oxyglobin has obstacles in its distribution strategy,
For example, some differences are water and sanitation, diseases (such as HIV), medicine and medical treatment. Water and sanitation is a factor which differs in developing and developed countries. The lack of clean water in many developing countries is one of the main issues. “In 2000, more than 830 million people in Asia Pacific region did not have access to safe drinking water.” (UN-HABITAT ORG, 2010).This sort of scenario does not occur in a developed country as it would not be seen as acceptable, and there would be a national uproar as citizens in developed countries know and stand up for their rights, unlike the poor people in these countries who know that nothing will help them. “UK water suppliers place the highest priority on assuring the quality of water provided to their customers.
