They are used due to their ability to infect a cell and integrate their genetic material into the host. Two types of gene therapy are: 1. Somatic gene therapy2. Germline gene therapy Gene therapy mainly targets single-gene recessive disorders, viral infections and acquired genetic diseases. Ethical issues arise when considering gene therapy due to a vast majority of reasons.
(Gabrielli et al., 2006) Furthermore, caffeine is known to have some influence on the cell cycle. Many researchers have performed studies that relate caffeine to cell death, in which refers to the preventing of cells from continuing through the cell cycle properly. (Pardee & Schlegel, 1986) Caffeine also causes cell arrest, or the capturing of a cell within a single phase in the cell cycle and causing it to die there. Besides having effects on the cell cycle, researchers also suggest that caffeine has the ability to enhance anticancer drugs. (Wang et al.,
The lab that was simulated directly correlated to many of the topics discussed in class, like explaining the importance of enzymes and measuring the enzymes’ ability to function under different conditions. The breaking of the toothpicks symbolizes the catalyzation of substrates in a cell. This deepens the understanding of the purposes of an enzyme and what affects each one of them. The conditions that were present in the lab showed that the enzyme is exposed is not perfect at all times and that the effect that they have is vitally important to the performance of the enzyme, and more importantly, the organism that it is living in. So this raises one question to mind; What causes the reaction rate to slow down the
The enzyme catalase is commonly found in animal and plant cells, but a substantial amount is found in liver. The liver detoxifies the blood to get rid of substances such as alcohols and drugs, in this case it will break down a toxic molecule called hydrogen peroxide H2O2 into 2 non-toxic products being oxygen O2 and water H2O. Other enzymes in the body that help with breaking down amino acids and fatty acids produce a significant amount of hydrogen peroxide, and without the enzyme catalase, hydrogen peroxide levels in our body could increase thus damaging tissue. A chemical reaction is shown below: 2H2O2 =2H2O + O2 This
(6) Although some ingredients are dangerous in sunscreen, sunscreen does way more good than bad. High factors of sunscreen prevent bad burns and give you a way lower risk of getting skin cancer, it is efficient and not expensive and keeps your skin healthy. Sunscreens limitations are little , of course it wears of and some UV rays do reach the skin, it is definitely better than wearing no sunscreen where your skin gets burnt and damaged and in extreme cases can get skin cancer like melanoma which is an extremely dangerous cancer. My concerns for the future of sunscreen is that people will add more and more chemicals to try make a stronger and better sunscreen and end up making a sunscreen that protects you from the sun but gives your skin new dangers just as bad as being exposed to the sun's UV
Environments that have either too low or very high concentrations of zinc have detrimental effects to living organisms. Living organisms are known to have evolved in the presence of natural levels of zinc and this plays an essential role in many biological pathways. For instance, many bacterial enzymes have zinc in their active or structurally important sites (25). They have evolved different mechanisms to maintain a constant desirable internal zinc concentration range, despite fluctuations in their external environment. This element that is important for all physiological processes has also for long been considered a drug.
Many people are forced to not buy the drugs they need to survive, which can result in deaths. Even some people that can afford their medicine have a very hard time finding a way to pay for their prescription. The government needs to change it, whether it be importing drugs from Canada, or enforcing price controls. The prices are far too high, and that is why millions of Americans do not take their medicine. Millions of people not taking their prescription is way too many, in fact one person not taking their medicine is too many.
In these countries, the country does not have the money to improve the health care with new technologies nor the money to treat all the citizens, and the people who live in poverty do not have the money to pay for their own treatment especially if it is not free. According to WHO ( World Health Organization), “around 1.2 billion people in the world live in extreme poverty, and that 1 billion people worldwide suffer from serious illness due to poverty”. According to Children International, “2 million children die each year from preventable diseases like pneumonia because families can’t afford treatment”. Fortunately, in Kuwait, poverty is almost non-existent, and a lot of the population is of the working class. For the citizens of Kuwait health care is free, where in other low-income and under-developed countries health care is not free or is inadequate, and this is because of the social gap.
Poverty: the state or condition where a person is unable to satisfy their most basic human needs such as water, shelter and food due to lack to money, there are two types of poverty: Extreme poverty and moderate poverty. Extreme poverty is when people cannot obtain adequate resourced to support the minimum level of physical health. Some reasons for poverty include: • Poor education • High levels of unemployment in a country • Low level of skills • Lack of access to services • Family history • Born into a poor environment People living below the poverty line are required to get government assistance, poverty rates have however decreased because of an increase in social grants. Types of Poverty: • Absolute Poverty o The chronic lack of basic food, water, health and housing. People living in absolute poverty tend to struggle to live and experience more child deaths from preventable diseases like malaria, cholera and water contamination.
In an advanced production world, non-eco-friendly products are gaining attention from the company as well as the mother earth. The waste that produced today will pollute the environment later. Styrofoam is used mainly for packaging due to its lightweight. But now, we suggest replacing Styrofoam to Mycofoam. Mycofoam main ingredient is mycelium.
No quick endospore stain was performed to validate this assumption since only one assigned organism was endospore forming and unlike Unknown #10, that organism was Gram positive. By Gram staining alone, it was safe to eliminate the three Gram positive bacteria that could have been assigned: S. epidermidis, M. luteus, and B. megaterium. The second step was to streak plate Unknown #10 to observe its macroscopic
If they go through with the pipeline act it could kill many Native Americans because we need water to survive. Since our bodies need water to survive why would we put Native American live in danger? The government does not give them much the way it is. It seems like they constantly take things that they deserve. This Native American village is the poorest in the world.
I believe Krugman did a great job in representing an important issue and backing up his claims. I do think he could have used more sources and quotes to back up certain points; however, he still presented factual information. I agree that solar and wind power would be an ideal alternative to current practices. Now that it is more cost-effective, government figures should be stepping in since there is physical evidence that fracking is detrimental to the health of humans and this planet. The info graphic in "What Goes In & Out of Hydraulic Fracking," presented some important statistics that supported Krugman’s logic in his article.
One of the most controversial projects for the United States to decide on was whether or not to build the Keystone pipeline. This topic forces the government to decide if economic development is worth the cost of endangering the environment. Though this pipeline will allow the United States to rely less on foreign oil, the pipeline’s lasting effects prove to be a factor that cannot be easily overlooked. The Keystone pipeline should not be built because it endangers the environment and has the ability to create catastrophic damages through pollution and habitat desecration. Pollution is a major factor that has to be considered when referring to the Keystone pipeline.
More than half a million children suffer from vitamin A deficiency, which cripples young immune systems. Inadequate supplements of vitamin A can lower child mortality rate by more than one-fifth” (“Heath of African,” par. 6). This disease has become an extreme problem for children because it can alter their growth and also ruin their immune system. With their health rates decreasing, children are more likely to become sick.
