'''[[Blood substitutes]]''' "When blood is lost, the greatest immediate need is to stop blood loss. The second greatest need is replacing the lost volume. This way remaining red blood cells can still oxygenate body tissue. Normal human blood has a significant excess oxygen transport capability, only used in cases of great physical exertion. Provided blood volume is maintained by volume expanders, a quiescent patient can safely tolerate very low hemoglobin levels, less than 1/3rd of a healthy person. However in extreme cases of oxygen deficit, artificial blood can fulfill the oxygen therapeutic function. Perfluorocarbons (PFCs), in particular, may be useful in cases of myocardial infarction or stroke because these small oxygen carrying molecules are able to pass clots that would normally block blood cells." |

'''[[Liquid breathing]]''' "A form of respiration in which a normally air-breathing organism breathes an oxygen-rich liquid rather than breathing air. It is used for medical treatment such as infants with acute '''[[Respiratory Distress Syndrome]]''', and could some day find use in deep diving and space travel. Liquid breathing is sometimes called fluid breathing, but this can be confusing because both liquids and gases can be called fluids." |

"Personal statements that get you into medical school"
I've wanted to be a doctor ever since I saw an episode of Mama's Family. And you know why? Cuz my Mama died when I was 12! Her lips were made of tin because we had bad insurance, and she had an allergy. She was allergic to tin. Watching Mama struggle with that tin allergy inspired me to become a dermatologist. In particular, I remember the way my mother's doctor talked about how bears changed her life. So I became one, but my patients flip everytime they find out I don't have a medical degree yet.
Hailing from Massachusetts, her doctor bet her life savings on the New England Patriots in the 1986 Super Bowl. I don't hail from Massachusetts, but I can sure spell it, and believe I would be a great fit for Harvard Medical School. My prenatal MCAT instructor,a pediatric gerontologist from Harvard, showed me the inseparable connection between medicine and Massachusetts. Not only do they both start with "M", but they're both multisyllabic words (at three and four syllables respectively), and roll off the tongue nicely. In fact, I am told they were my first words: "Medicine. Massachusetts." I said these words while wearing my grandfather's stethoscope. You must understand that my father is a poor man who almost never gets to leave the coal mine, so I have never even been to New England. This is part of the reason why I have always dreamed of becoming an emergency gynecologist. Actually, I show up at the ER every night to volunteer as an emergency gynecologist.
I've only been arrested 3 times - I believe this shows my commitment to medicine. Especially since 2 of those arrests were for assault charges, even though I know the patient needed CPR. How do I know this? The patient told me she thought she needed CPR. So I administered it. I even performed CPR on one of the two guys I beat up and saved him from dying. But he died anyway a day later. Oh well!! Death is a part of medicine, right? Which leads me to tell you about my research about the socioeconomic effects of genital herpes in nematodes. After working closely with the nematodes, I learned firsthand about the social stigma associated with contracting interspecific genital herpes.
This is also why I have decided to file as a disadvantaged student. During my first two years of college, despite my poor grades and multiple suspensions for plagiarism and seducing the dean's wife I came to the realization that a career in medicine would let me combine my love of science and my love for helping people without forcing me to make unnecessary financial sacrifices. I do, however, understand the financial burden of attending medical school, and am willing to make that financial sacrifice. After all, I know what sacrifice means. While saving starving African babies during my summers, I lived in a hut and only had twigs and mud to eat and drink. Despite this, neurosurgery is my passion. I cannot understand how someone would squander 4 years of professional education on a primary care specialty. I'm too talented to waste my gifts just to become a glorified nurse practitioner. I've always believed I had an above average brain-to-body size ratio, and I believe that will help me in becoming a better neurosurgeon. Oh course this gift has always made me look like a watermelon wearing a toupee, but that has humbled me beyond my years.
Speaking of years, this would be the pertinent place to mention that I graduated college at infancy, and have been subsequently granted multiple honorary degrees in underwater basketweaving from major universities.
In addition to the weaving, I minored in communications. To be honest, I am not sure this medicine thing is going to pan out, but I am giving it a shot! I figure the minor will be good backup, just in case. In my upper division communications classes, I learned to save the best part of a paper for last. I am sure that once you hear this story you will let me in, so here we go.
This one time I took an hour to decide between paper and plastic. The supermarket bagger, with nerves of steel, gazed at me with passion, the same kind of passion I have for both medicine and communications. If my indecisiveness for career, or even specialty, isn't enough to impress you I’m also really ridiculously good looking as my mother often told me before she died of a combination of syphilis and a tomahawk to the head. The syphilis *I* gave to her and the tomahawk from our cat, Muffins, who flung it off of a table. Can't you see how I'm disadvantaged and deserve to get in?! And by "flung it off the table," I mean that I was about to behead my baby sibling on the table when the darn animal happened to be in the way and deflect the path of my mortal weapon. Nevertheless, my passion for anatomy prevailed and I dissected my mother. Some claim that it was my dissection and not the syphilis that made her die, but she seemed pretty active writhing in that bathtub. In my dissection I found her syphilis and with my microscope and Muffins, I created a mutant strain which is controlling cat populations around the world, much to the delight of my new best friend, Bob Barker. You should have a letter of recommendation from him soon.
Maya Angelou once told me, "get away from me! Mind your own business, young man." I felt a heart to heart connection, and took her advice and decided what she really meant was to stay away from business, and live life as a young man helping people, because helping people is my second favorite thing to do next to helping animals and the rain forests. Medicine would help me do that.
Interesting articles
Retinex Color Theory "Subjective constancy and a feature of the human color perception system which ensures that the perceived color of objects remains relatively constant under varying illumination conditions. A green apple for instance looks green to us at midday, when the main illumination is white sunlight, and also at sunset, when the main illumination is red. This helps us identify objects. The different cone cells of the eye register different ranges of wavelengths of the light reflected by every object in the scene. From this information, the visual system attempts to determine the approximate composition of the illuminating light. One application of theory is that a black and white image superimposed on a monochromatic image could create the illusion of a complete range of colors."
Candirú "The candirú parasitizes other fish. It swims into the gill cavities of other fish, erects a spine to hold itself in place, and feeds on the blood in the gills, earning it a nickname as the "vampire fish of Brazil". It is feared by the natives because it is attracted to urine, and if the bather is nude it will swim into an orifice (the vagina and even the penis—and deep into the urethra) and because of spines protruding from the fish, it is almost impossible to remove except through surgery. The fish locates its host by following a water flow to its source and thus urinating while bathing increases the chance of a candirú homing in on a human urethra. Natives have also been known to bathe facing the current, as doing so would decrease the chances of the organism lodging itself in the rectum.[citation needed] Other orifices such as the penis or vagina are covered up with the use of hands."
Angelman Syndrome "Characterized by intellectual and developmental delay, speech impediment, sleep disturbance, unstable jerky gait, seizures, hand flapping movements, frequent laughter/smiling and usually a happy demeanour. Those inflicted were originally described as 'puppet children', but this description is now considered pejorative. This condition is a classic example of genetic imprinting caused by deletion or inactivation of critical genes on the maternally inherited chromosome 15. Because Angelman Syndrome is not an illness, but a genetic condition, there is no currently available cure."

Uncanny Valley "As a robot is made more humanlike in its appearance and motion, the emotional response from a human being to the robot will become increasingly positive and empathic, until a point is reached beyond which the response quickly becomes that of strong repulsion. However, as the appearance and motion continue to become less distinguishable from a human being's, the emotional response becomes positive once more and approaches human-human empathy levels. This area of repulsive response aroused by a robot with appearance and motion between a "barely-human" and "fully human" entity is called the Uncanny Valley. The name captures the idea that a robot which is "almost human" will seem overly "strange" to a human being and thus will fail to evoke the empathetic response required for productive human-robot interaction."
Neodymium magnet "A powerful magnet made of a combination of neodymium, iron, and boron (Nd2Fe14B). Used for stabilization and angular head motors in computer hard drives, neodymium magnets are also popular with hobbyists, and a small magnet can have amazing properties. Neodymium magnets should always be handled carefully. Some that are slightly larger than the size of a penny are powerful enough to lift over 10 kilograms. They are hazardous; able to interfere with pacemakers and implanted heart devices with deadly consequences. Larger neodymium magnets can severely pinch skin or fingers, or even break bones when suddenly attracted to a magnetic object. Operating a large neodymium magnet close to smaller magnetic objects (keys, pens, etc.) and larger magnetic surfaces (radiator or a car, for example) can be dangerous if the person is caught between the magnet and the magnetic object or surface.If swallowed, neodymium magnets can cause lethal conditions by joining up inside the intestine."

Ebu Gogo "A human-like creature (or race of creatures) which appears in the mythology of the people of the island of Flores, Indonesia, of similar form to the leprechaun or elf. These "little people" are said to be about one meter tall, covered in hair, pot-bellied and with ears that stick out. They are held to walk somewhat awkwardly and are often said to be 'murmuring' in what is assumed to be their own language. It is also said by the islanders that the Ebu Gogo can repeat what is said to them in parrot-like fashion. The discovery in 2003 on Flores of remains of a meter-tall hominid, Homo floresiensis, suggests a more literal interpretation of the Ebu Gogo stories. H. floresiensis survived at least until 12,000 years ago and probably survived longer."
Ryugyong Hotel "A towering, empty concrete shell that was once intended for use as a hotel in Sojang-dong, in the Potong-gang District of Pyongyang, North Korea. The hotel's name comes from one of the historic names for Pyongyang: Ryugyong, or 'capital of willows.' Its 105 stories rise to a height of 330 m, and it boasts some 360,000 m² of floor space, making it the most prominent feature of the city’s skyline and by far the largest structure in the country. North Korean leadership envisioned the project as a channel for Western investors to step into the marketplace. A firm, the Ryugyong Hotel Investment and Management Co., was established to attract foreign investment. A representative for the North Korean government promised relaxed oversight, saying, 'The foreign investors can even operate casinos, nightclubs or Japanese lounges if they want to.' Construction started in 1987 and ceased in 1992. The basic structure is complete, but no windows, fixtures, or fittings have been installed, and it has never been certified safe for occupancy. The concrete used to build the hotel was very poor, making the structure unsafe, and it has worn down even more over the years. The North Korean government is trying to invite foreign investment of $300 million to improve and finish the hotel. In the meantime, it has removed the Ryugyong from maps and stamps."
Millau Viaduct "A large cable-stayed road-bridge that spans the valley of the River Tarn near Millau in southern France. It is the tallest vehicular bridge in the world, with one mast's summit at 343 metres — slightly taller than the Eiffel Tower and only 38 m shorter than the Empire State Building."
Mont Saint-Michel "Before the construction of the first monastic establishment in the 8th century, the island was called Mont Tombe. According to legend, the archangel Michael appeared to St. Aubert, bishop of Avranches, in 708 and instructed him to build a church on the rocky islet. Aubert repeatedly ignored the angel's instruction, until Michael burned a hole in the bishop's skull with his finger. The Mont Saint-Michel and its bay were added to the UNESCO list of World Heritage Sites in 1979, as they rank very high on such World Heritage Site criteria as cultural, historical, and architectural significance, as well as human-created and natural beauty."
Vajont Dam "Completed in 1961 under Monte Toc 100 km north of Venice, Italy, it was one of the highest dams in the world measuring 262 meters high, 27 meters thick at the base and 3.4 meters at the top. On October 9, 1963 at approximately 10:35pm, the combination of the third drawing-down of the reservoir and heavy rains triggered an enormous landslide of about 260 million cubic meters of forest, earth, and rock, which fell into the reservoir at up to 110 km per hour (68 mph). The resulting displacement of water caused 50 million cubic meters of water to over top the dam in a 250-meter high wave. Despite this, the dam's structure was largely undamaged — the top meter or so of masonry was washed away, but the basic structure remained intact. However, the flooding caused by the landslide destroyed the villages of Longarone, Pirago, Rivalta, Villanova and Faè, killing 1,450 people. Many small villages in the territory of Erto e Casso and the village of Codissago, near Castellavazzo, were largely wrecked. Almost 2,000 people perished. Damage was also caused by the air displacement caused from the immense 'splash' in surrounding villages."
Exoplanet "An exoplanet is a planet beyond the Solar System. As of May 2007, the count of known exoplanets stands at 241. The vast majority have been detected through various indirect methods rather than actual imaging. Most of them are giant planets likely to resemble Jupiter more than Earth. Most known exoplanets orbit stars roughly similar to our own Sun, that is, main-sequence stars of spectral categories F, G, or K. One reason is simply that planet search programs have tended to concentrate on such stars. But even after taking this into account, statistical analysis suggests that lower-mass stars (red dwarfs, of spectral category M) are either less likely to have planets or have planets that are themselves of lower mass and hence harder to detect. Recent observations by the Spitzer Space Telescope indicate that stars of spectral category O, which are much hotter than our Sun, produce a photo-evaporation effect that inhibits planetary formation. A subset of exoplanets are interstellar planetary masses, objects which have equivalent mass to planets and are not gravitationally bound to any star, and move through space as independent objects. Several astronomers claim to have detected such objects, but those detections remain unconfirmed. Some astronomers refer to these objects as 'planets', usually because they believe such objects were planets that were ejected from orbiting a star. However, others believe that the definition of 'planet' should depend on current observable state, and not origin. Additionally, these objects may form on their own through gas cloud collapse like stars; in which case they would never have been planets." |
