Our Amazing Human Body: Brain

I think the most amazing organ in our body is the brain, is so wonderful that is the organ in charge most of the human body functions.

Well, the brain is located in the head protected by the cranium. Besides, of all the weight of our body, the brain only represents between 0.8% and 2% (approximately 1300 to 1600 grams).

The functions of the brain are many, I might write all the day about the brain, but that is not the idea, so, I will summarize.

The brain processes sensory information, controls and coordinates the movement, behavior, feelings and can prioritize homeostatic body functions such as heart rate, blood pressure, fluid balance and body temperature. However, the responsible for carrying automatic process is the medulla oblongata.

What illnesses can alter its normal functioning? Inflammation in the brain can lead to problems such as loss of vision, weakness and paralysis. The loss of brain cells that occurs when one suffers a stroke, can affect the ability to think clearly. Brain tumors can also press some nerves and affect brain function. Some brain diseases are genetic; in others, such as Alzheimer's disease, the cause is unknown.

A balanced diet is essential to promote brain health. We must also avoid stress, proper rest and encourage neural connections learning something new every day.

Important information: 

• Only about 5 minutes without enough oxygen for brain, damage occurs. 
• There are no pain receptors in the brain itself, is, this organ can not feel pain.

The best holidays OR concert ever

Everytime that I must choose something, makes me think a lot, but in this case it was very easy…

The best holidays were four years ago, exactly in february of 2012. With my family  we went to my aunt house to a town named Rafael, in Tomé, in the south of Chile.

Well, the place is countryside, the house is in a hill and when you see around everything are trees, amazing! Also in the surroundings there's a creek that pass for the forest (that is in front of the house). In the night everything's so quiet, without noise, and the sky is full of stars, such beautiful.

But  the place has something "spooky" (isn't spooky)  because like 600 metres far away from the house there is a abandoned house, it's private property but I went, and the house is very impaired and covered by trees, and to get there you must cross a  small road, which is covered by trees.

What else? The holidays were amazing because, first the aunt house has a pool, also the beach is half an hour. Second we visited a lot of places, wonderful places. And the last and most important we had fun in family.

PD: I don't have photos because are in my laptop, and the laptop died.

A country you would like to visit.

I have never been to England, so I would like to go. Why? Well, I think the culture is very interesting and so different from here.  Also (I cannot leave it out), I love their accent, is so refined.

Talking about what I know about the country, obviously only I know what I've seen on TV or surfing the web. First, England  It is part of Britain. The capital is London, and if you don´t know has a great tourist attraction, like The London Eye, British museum, Science museum, among many other places that they must be wonderful. 

A little culture…

Architecture: Many ancient stone monuments still standing were built in prehistory.  Among the best known include Stonehenge, Standing Stones known as The Devil's Arrows, Rudston monolith and Castlerigg stone circle.

Gastronomy: Examples of English food, include the Sunday roast, a dish usually made with beef, lamb or chicken, served with mixed vegetables. Other is the full English breakfast, usually consisting of bacon, grilled tomato, baked beans, fried mushrooms, sausage and eggs.

Literature and poetry: One of the most biggest author is William Shakespeare, other known authors are Dickens, Brontë sisters, Jane Austen, Kipling,  C. S. Lewis, J. K. Rowling, etc.

Music: Many nursery rhymes are of English origin, or associated with English culture, as "Twinkle Twinkle Little Star". In the field of popular music have many English bands and solo artists like The beatles, Rolling Stones, Queen, The who, among others.

What would I like to do there? Visit all tourist attractions, tour the city, all I can do. 

Would I like to study/work/live there? I would like study or live there, I really would like to better learn the language and to learn your accent, so either of the two options would be good for me.

My blogging experience

How to start? Well, the blogging experience is something totally new for me. I had never written a blog in my life, so far. Also I think it is a wonderful experience, where I learn to improve my grammar and spelling, and not only that, It is an opportunity to express our thoughts.
Talking about my writing skills, I think  they are much better than at the beginning of course, I learn new words like "mischief", is a fact that writing the blog has done to expand my vocabulary.
What else I would like to write about? I have many ideas I would like to add in the future,  one of this ideas is "talk about the environment", and not only that, can convince people who read the blog that the environment is important, and we must take care. Also I want to write about daily things, with which people feel identified. Other idea is write about places of the world, but places that nobody knows, I think is a very interesting and intriguing idea. This are some ideas.
To sum up, the blogging experience is so fun, cool and refreshing. If you want to start a blog you must know that you need much inspiration, but worth exploiting our head trying to find inspiration.

PD: This is my last entry, but I hope to see you soon. xoxo

From the invisible to the visible world and back...

What do you think when you hear the words nanotechnology or micro-technology? Well, I thought it was something small, but, How small? Let's see it.

• What are they? "Nanotechnology " is used extensively to define the science and techniques applied to the nano scale level , this is extremely small(nano) measures for working and manipulating atoms and their molecular structures. Micro-technology is the technology that enables us to manufacture things on the micron scale . A micron is a millionth of a meter, or to give a clearer idea thousandth of a millimeter.
• Materials: Such as carbon nano-tubes and fullerenes other , and various nanoparticles and nanoroides.
• Instruments: The atomic force microscope, the scanning tunneling microscope, among others. 
• Techniques: X-ray lithography, optical lithography, the electron beam lithography or nanoimprint lithography,etc.
• What they are used for?                     

1. Stockpiling, Production and energy conversion.
2. Weapons and defense systems
3. Agricultural production.
4. Treatment and water remediation
5. Diagnostic and screening of diseases.
6. Drug delivery systems.
7. Food processing.
8. Remediation of air pollution.
9. Construction.
10. Health monitoring.
11. Detection and control of pests.
12. Control of malnutrition in poor places.
13. Computing.
14. Transgenic foods.
15. Molecular thermal changes (Nanotermología).

• What importance they have in your career? I think that the nanotechnology and microtechnology are very important in my career because the biochemistry is a science that need this technology for the investigation.
• What impact they may have in human welfare? This type of technology has a big impact, especially in health.
• Disadvantages: 

1. Are important if changes in the structure of society and the political system.
2. The Power of nanotechnology could be the cause of a new arms race between two competing countries. Production of weapons and spy gadgets could cost much lower than the current being also the smallest, powerful and numerous products.
3. The Inexpensive production and duplication of designs could lead to major changes in the economy.

• Advantages: 

1. The Water scarcity is a serious and growing problem. Most of the consumption of water used in production systems and agriculture, which manufacture products using molecular manufacturing could transform.
2. The Infectious diseases cause problems in many parts of the world. simple products such as pipes, filters and mosquito nets could reduce this problem.
3. Information And communication are useful tools, but in many cases do not even exist. With nanotechnology, computers would be extremely cheap.

Websites you enjoy visiting

Let´s see, I enjoy visiting many websites, but if they are only related to my career I choose two:    

        I) OMIM (Online Mendelian Inheritance in Man):               

• Link:  http://www.omim.org/ 
• OMIM is a comprehensive, authoritative compendium of human genes and genetic phenotypes that is freely available and updated daily. The full-text, referenced overviews in OMIM contain information on all known mendelian disorders and over 15,000 genes. OMIM focuses on the relationship between phenotype and genotype. It is updated daily, and the entries contain copious links to other genetics resources.   
• Why I like it? Because I think that OMIM is the most incredible website about disorders in the world, and  I really love everything about the mental diseases. I recommended it 100 percent. Currently I visit the website when I have free time, maybe once a  week.

        II) NCBI ( National Center for Biotechnology Information):

• Link: https://www.ncbi.nlm.nih.gov/
• The NCBI has been charged with creating automated systems for storing and analyzing knowledge about molecular biology, biochemistry, and genetics; facilitating the use of such databases and software by the research and medical community; coordinating efforts to gather biotechnology information both nationally and internationally; and performing research into advanced methods of computer-based information processing for analyzing the structure and function of biologically important molecules.   
• I like this website, because if you want about the latest research, something about science, among other, you should enter to this page. How often I visit the site? Well, not ussully, but when I do, I really enjoy surf in the website. 

The most enjoyable subject thus far...

To choose my favorite subject is not too easy, there two subject that I like too much, but I just have to choose one…

Well, my favorite subject is “Chemical laboratory techniques”, which consist in learn to use the instruments of laboratory and also we learn the techniques more basics, like how pull apart two subtances  or how make a titration, amog other things.

Why I like this subject? For the simple reason that I really like use my hands to make some destillation, even though I am very bad and all the time I make a mistake, but I know that I need practice.

I think that it is obvious that this subject is more practical than theoretical, but that doesn’t mean that is not theoretical.

Other information about the subject:

·         There are seventy-six students in the subject

·         The coordinating theacher is Aida Ahumada T.

The importance of the theacher in the lab is very important, because the students need some help, sometimes it can happen an accident. And the importance of the subject in the career is very high because is the base for every subject in the future.
