Where will you be in 2031?

Now that we have started genetics and watched the Miracle of Life, we have been given an assignment in which we are supposed to wright about ourselves in 2031. So here is my letter to myself from 2031:

Dear David,

I am currently living in Barcelona where I play basketball for their first team. I came not so long ago from Sienna, where I played for Montepaschi. I currently live in a house near the beach with my family. Life is great and I earn about 700,000 euros per year, but I earned a lot more in the past. I attend practice as usual and also spend quality family time. As I have mentioned my career in sports is doing well and is aimed towards a great direction. I visit my family weekly so we are in close touch. There is nothing to complain about, living a dream! My wife is from Italy, where we met when I was in Sienna. So far, I have one child, his name is Josh. Hes 2 and really cute. I wouldn't give up my life for anything, the life in Barcelona is simply a dream. My dream did really come true. Playing basketball while living a fantastic life and being next to my family is a dream few people accomplish. Over all, my career is successful and me and my wife are happy with Josh.

Best Wishes,
Future David

See you soon!

Mitosis vs. Meiosis



http://www.youtube.com/watch?v=GK3eHNu9zsA&feature=related




At the beginning of this unit I was lost when someone would ask me this same question, how is mitosis different from meiosis? Well now I can answer it. To begin with, mitosis is asexual reproduction while meiosis is sexual reproduction. However, the both go through the same stages of the cycle but the end is what separates them into two. In mitosis, there are two daughter cells that have the same exact DNA strand, while in meiosis the 4 daughter have half of the chromosome or DNA strand. This happens because of the two parents giving half and mixing them together. In mitosis the organism can reproduce by itself while in meiosis two "parents" are needed. In meiosis you get one set of chromosomes from your mother and one from your father. Basically in mitosis, the organism reproduces by itself duplicating its DNA, while in meiosis you need the two gametes for the reproduction to occur. At the end of meiosis the daughter cells have mixed genes from both parents. Over all, I have learned and preserved a lot of the information. I am really glad I was able to learn this so quickly and effectively as well.

Cancer Warrior

In this One World essay the main topic is cancer, and medicine, and on how they actually affects our society. Before we were supposed to write this, I was assigned to watch a movie called Cancer Warrior. This movie specialized in the field of cancer medicine and demonstrated some new knowledge I never knew. It all started with the medicine that prevented the growing of the tumor. Throughout the short clips, many scientists combined their thoughts into what has been a major step in curing cancer. In order to establish this, they focused on many specific parts that I found fascinating they played such a big role. For example, the blood vessel business really amazed me. I never knew that they played a role in the evolution of the tumor. Turned out that if you stop them, the tumor potentially should not grow. Along with that, there were many more aspects that were fascinating but you will have to read on. In this essay you will experience and learn about the medicine that is so risky, yet so crucial for people’s survival.

As we all know, the crucial medicine we are in need of has its pros, but the medicine being tested has its pros as well. To begin with, I will talk about the benefits of the medicines released. Firstly and most importantly, they give the patients a sense of survival. They help in the tumor reduction process and could potentially cure your cancer. For example, the medicine in the video helped the reporter for a matter of months. Of we work on that, the medicine could help stabilize the cancer and eventually cure it. Next, I will tell the benefit of having the medicines tested before the human population can use it. To begin with, the medicine might have unwanted side effects that could possibly make the situation worse. Instead of curing, it would just work against the situation. In this way, the scientists check it before releasing it. Everyone wants to make sure it really works, and that’s when the volunteers come in handy. They are willing to risk their life for the sake of living, and that is what we should respect. I am sure that everyone wants the best for themselves, and this is what can allow you to do that. All together, there are many benefits when you look at it, whether the medicine is released sooner or later.

It has been controversial whether patients with serious illnesses should get experimental drugs but there is a big problem regarding this. Taking an untested drug is like risking your own life, the scientists and you do not know what to expect. It’s like entering a new world no one knows about. You do not what will happen to your body and your current situation. I can understand why this could potentially happen, but making the situation worse is not what we want to do. However, many people, as you can see, are willing to take that chance because they know they won’t live that much. But, sometimes waiting is the actual cure. After all, it’s an all or nothing situation, die or live.

In this next section, what will be discussed are the pros and cons of the fact that experimental drugs should be released before their full testing process is complete. To begin with, the cons will be opened to thought. Firstly, the drugs are not fully secure. Neither you nor the scientists know what will happen to you when the doses are given. It is a true mystery and many times the medicine has failed, leaving the patients with more problems to deal with. Some unwanted side effects would include losing of hair and internal problems. For example, a drug is released too early and has not been tested yet. Since many ill patients need the cure, doses are delivered to each one of them. Half way through the year, the scientists discover the medicine is bad for your health and is pulled back. However, now many people have suffered the consequences and have even bigger problems. This is the types of situations we want to avoid which leads us to the pros of the situation. There are many serious situations with lives on the end. A medicine that should work is released because of the great need. It has been partially tested and seemed to work. Once this is released the people adopt a feeling of hope and a chance of survival. Along with this, the product has seemed to be working and put a stop to the growth of the cancer and tumor. In this situation the experiment has worked and many lost lives have been saved. The risk has paid off and established a new era in medicine. These here in the example are the pros. A great success that was bound to happen. Over all, releasing a new experimental medicine is a risk that some take and some don’t. Sometimes luck will be on your side while sometimes it won’t. It’s life, sometimes it works and sometimes it doesn’t.

Next, I will identify the possible benefits of releasing a drug too early. As I have explained previously, the drugs released early have not finished their testing process but are identified as helpful ones. And out there are many cancer patients that have their life on the edge and are in desperate need of help. This drug is used to put a halt to the growing of the tumor. Turns out that it has helped the society and given them a sense of hope and personal confidence. This means the risk was worth it and the solution has. If the drug was released a little late, many people would have lost their lives and caused grief to their families. Releasing a drug early can save a lot of lives and be worth it at the end. Just imagine if two more months were added to the testing, hundreds might have died. After all, there is a big chance of the worse but sometimes it can save the whole world.

In this last part, I will talk about the risks the patients take when receiving doses of an untested drug. When taking a drug that has not been fully tested, the patient is basically risking his life. He does not know what will happen to him if he continues, but he hopes for the best. It has come to the point where either it will get worse or he will be cured. It’s the matter between life and death, to be or not to be.

In conclusion, I believe that this movie really taught me a lot about medicine and cancer and opened my eyes to this terrible disease. I can step into a patients shoes and feel their feelings. With this new information, I believe I have progressed in knowledge and feeling.
