Dear Reader, This magazine was created with the purpose of becoming a scientific magazine, which would provide the readers with scientific facts and entertainment as well. Our group of writers tried to imbue this magazine with our personalities but that didn’t quite work as well as planned because we couldn’t figure out how to do this. We encountered many design errors and discrepancies within the natures of how we wanted the magazine to look. Most crises came from individual arguments between the two main design freaks Ethan and Gabriel. Some other arguments came between Brayan and Ethan over the logo. Things got eventually sorted out like Ethan’s logo won out and, like most things do, however there would always those slight looks that would convey, “You won the last one, I am going to win this one.” Raised voices, not necessarily a bad thing, were a constant part of our group’s routine on a daily basis. We are proud to admit that there were some days where procrastination was the name of the game, but we did manage to complete everything on time. The topic of the magazine, was not really something that had to be disputed, to many of our surprises. All in all, this magazine was designed to provide new scientific developments and help readers understand biology better.
Enjoy, The Editors of Inside Human Gabriel, Daniel, Brayan and Ethan 2

HITCHHIKE WITH A VIRUS Using Viruses as Transport By: Gabriel Manners Viruses are not always harmful. New genetic research by Mark Bailey, Ph.D. ,a professor at the University of Glasgow and others proves that viruses are some of the most useful resources for healing diseases that we have at our disposal. Bailey has been working on a cure for idiopathic generalised epilepsy, (IGE), using a process called viral vectors. “We strip out all the genes that the virus doesn’t really need, and also the the genes that allow the virus to replicate and make new copies within the cell... and then we insert the correct human genome,” Bailey said. “ These are called ‘gutless’ vectors, as they only have a little bit of DNA that actually belongs to the virus.” Genetic studies have come a long way over the last couple of years. From being able to find out someone’s ancestors, scientists are now able to use the viruses to cure diseases such as some types of epilepsy. Science’s most recent breakthrough in this area was to use HIV virus particles to make an exact copy of the human genome. Using this technology, scientists are able to inject the virus into the body. This process might seem dangerous, but the virus has all of the original messenger RNA taken out. These helpful viruses are called Viral Vectors. “Its the power that these viral
vectors gives scientists to manipulate what cells are doing, either cells in a culture, or cells in an organism,” Bailey said. More recent breakthroughs have prompted scientists to try and gain a greater understanding of the human genome. This understanding has provided the basis for

realizing how some types of epilepsy are spread, as well as other genetic diseases. Scientist are now able to trace people’s ancestors to find out if they have a risk for IGE. These advances have paved the way for new
technology that can better cure and trace genetic diseases. The new technology can also increase awareness for STDs and other viral conflictions and is the basis for projects that can modify the genes of humans to make
“supermen.” “The future of genetic research is mainly focused in one direction, which is the pursuit of viral vectors to enhance current medicinal research,” Bailey said. New research in the viral vectors field involves the use of virus protein shells to act as transport for human genomes. This process enables scientists to cure genetic diseases by injecting a virus with the correct gene sequence into the human’s body. The virus then replicates itself using its normal habit of rapid replication. This process enables scientists to implant the correct genome if the subject has a negative genetic mutation. The rapid replication of the virus helps the correct gene sequence to become substituted throughout the subjects area of interest. This research can be used to help cure patients suffering from a variety of genetic illnesses. The different diseases act in different ways. While some inject their DNA, others cure in different methods. “It is the case in retroviral or lentiviral vectors, because that is how they were meant 5
to work.” Bailey said, “You are deliberately trying to get it into the genome because thats how it works.” The modern virus has many applications in today’s viral vector medicine. The most commonly used viruses are the lentiviruses, which include mainly sexually transmitted diseases such as the HIV virus, retrovirus, which cause most types of common cancers and Av or adeno-viruses, which cause the common cold and other types of respiratory diseases. Most people carry these viruses with no symptoms for their whole life. The adenoassociated-virus or AAV, which is small even for a virus, is not related to AV, but can only be made in a cell that already carries the genes from AV. It does not really cause any notable human diseases and many of us carry it with no symptoms. These are the main virus protein shells that scientists can use for the viral vector process. To use these vectors correctly, the scientists must make sure that only the original mRNA left from the virus is the bits used for the virus’s replication cycle. This new virus, mixed with the correct gene sequence, spreads the correct genome throughout the body, temporarily or even permanently curing the genetic disorder. “Therapy is anything you do to try and help the patient to suffer less...,” Bailey said, “Gene therapy is simply trying to use genes to ameliorate suffering.”
Gene therapy describes a process in which genetic diseases are cured using viruses. Viral vectors enable scientists and doctors to make huge advances in genetic medicine to benefit future of generations. New medicine therapies allow genetic technologies to advance and scientists may try and use higher risk experiments, in the future because people will be healthier. “Humans might evolve into the perfect superhuman,” Bailey said. More applications for this technology include transferring different traits through animals or fruits to make them more resistant to diseases. This works by ‘breeding’ the genome

genome.
“A clinical trial is where you test whether a typical therapy to ask is this agent safe to use.” Bailey said Clinical trials are used to test the different therapies that can be used. During the process of gene therapy, the virus has only its original reproductive mRNA or DNA and the new genome pattern that scientists want to implant. The virus attaches itself to the host cell,and then it breaks the outer wall of the cell and releases their mRNA into the body of the cell. If the cell is a bacteria, the virus is known as a bacteriophage. The cell automatic response takes the mRNA into the nucleus of the cell to deliver its message to the DNA. However, in a normal virus the cell’s mechanisms get hijacked and the cell starts to make other virus particles instead of normal products. In the gene therapy process, the virus’s initial DNA is left intact, but only the parts that hijack the cell’s machinery to make new virus DNA. In gene therapy, the virus’s DNA has been replaced with the correct genome pattern. This means that the cell takes in the new genome and replaces its own genome with the new information and the virus then manufactures new copies of the healthy genome in virus protein shells. The process then repeats itself again with multiple cells, until most if not all of the cells in the mutated area are carrying this new genome. While this process may be revolutionary, it is not without risks. “DNA is a code, a string of A,C,T and G,” Bailey said. “That code is read and that reading produces individual proteins that

precisely correspond to what was encoded in the DNA sequence.” In gene therapy the whole point of the process is to get the chosen gene to express itself into the original genome pattern. This happens when the virus injects its genetic matter into the cytoplasm of the cell. The genetic matter gets drawn into the nucleus, where it is read by the cell. Its protein then molds with the original genome. This can lead to an over-expression, which causes organ failure and might even cause the cell to mutate. All of these things can be fixed in the initial design of the viral vector. “I think there are four main risks to using gene therapy,” Bailey said, “Immune reaction, mutation, the gene jumping into the wrong genome and the general risk of the unknown.” This process is not always riskfree. The virus can spread to other parts of the body, not

the cell is producing excess amounts of the virus’s protein shell, causing harmful effects to the rest of the body. The viral vector could also cause the body to have a negative immune response to the foreign particle. The virus might also infect other individuals who have nothing wrong with their genomes. If this latter possibility happens, it could have serious repercussions on the healthy individual’s children and their general health. However these risks are well worth it because gene therapy can cure many types of ailments with limited effort. DNA needs to be

expressed for the modified gene to actually have an effect. “The gene you’re putting into the cell is the gene of interest,” Bailey said. “Those genes get turned into whatever protein it is you’re trying to put into the cell.” Gene expression enables the cell to process the gene and manufacture the corresponding protein. These proteins are used to transfer the new genome to all of the surrounding cells. This transfers the new genome to the rest of the tumour, if that is what you’re trying to cure. If it is a disease the vector is trying to cure, then the genome will jump into the original genome to meld with the original genome and temporarily or permanently fix the gene pattern that is going wrong. “This is a subject that I talk about with my students,” Bailey said. “If you think about what it takes for what you think of as a human trait, think about how many genes it takes to make a difference in that trait.” The idea of making a superhuman, by altering his or her genome, is impossible at this time. Every gene that needs changing has to be changed in hundreds of thousands of cells in the body at the same time. Even though you only need to
change 10 percent of the cells, it is still impossible for even eye color. Their hair color, the eye color, everything in the body is in one way or another related to the genome. Viruses manipulate this code to change things to the way they want them. This is how gene therapy works. This process may be referred to as Doctors in the Flesh because the viruses are using their built-in mechanics to edit your genome. Unexpected things might happen. Examples of these unexpected things might include occurrences of

tumours, which are caused by accidental mutations in the gene sequence that is being transferred from the virus into the cells original sequence. These mutations are like any other. They are the result of an error in the gene sequence. In some cases the mutation is minor, such as an unusual eye color. However, when a virus causes a mutation in the gene sequence, it means that something has changed in the coding of the DNA. That can cause additional risks, such as tumor cells forming.
“You can maniuplate the behavior of those cells in many ways,” Bailey said 8
The superhuman concept is far fetched, but not an impossibility in the future. “In 20-30 years this may be possible.” Bailey said. “However at the current time, medicine and technology have not progressed far enough, nor has the human mind in preparation for this advancement. However, the upcoming possibility of a “superhuman” is on everyones mind in the genetic community. This would lead to the initiation of more and more creativity, as we would unlock the power to explore farther outside and inside of our planet.” Bailey and his
colleagues predict that this technology will allow humans to explore the deeper reaches of the ocean, because they would be able to withstand more pressure. Bailey also believes that in 20-30 years, humans would have the choice to have “designer babies.” babies that have predetermined traits chosen by the parents. Couples could also have the choice of whether they wanted their baby to have genetic modifications, such as gills, which would be achieved by splicing fish genes together. This technology is going to evolve. “People are going to always going to be discovering at one point or another. All these advancements are taking place in front of humanities very eyes,” Bailey said. “All we have to do now is continue on the path were taking and watch as it all evolves. This process is completely natural. All that really matters ahead of us is to learn more about the other areas of technology that will allow for these enhancements.”

DOCTORS IN THE FLESH The Story of an Otolaryngologist By: Daniel Kauffman n a typical day Dr. Abib O Abegtoba runs around a clinic treating people and other days he
would be in the operating room working on patients and parts of the days he does research. He is training to become an ENT physician. Abegtoba works with the five senses besides touch. Otolaryngologists are physicians trained in the medical and surgical management and treatment of patients with diseases and disorders of the ear, nose, throat (ENT) and related structures of the head and neck. They are commonly referred to as ENT physicians. Right now there is a need for doctors. Many people don’t know how many different specialties that they can follow. One good one to follow is ENT physicians. “A lot people don’t actually know what we do,”Abegtoba said. “I sort of check the ears, nose and throat. I chose the sinus surgery and it is actually quite a lot. It is very complex surgery and the neck itself is one of the more complex parts of the body. ” When people come to Memorial Hermann Hospital in the doctors have to diagnose someone, it is a very long process. First he have to get the history of someone and their illness. He has to ask questions and get all he needs to know. That is why doctors have to ask so many questions. Once they have all that information they have what they call a differential diagnosis. Then after they have the background information then he can start running tests like a CAT scan an MRI and X-ray among others if needed. Then if they feel like they need it they can run a little more invasive tests. After they have all of this then he should know what it is. For each specialized physician the process is different and there are lots of specialized

In the ENT (ear, nose, throat) there are still many different physicians. There is ontology ear doctors who deal with the ears not just worrying about hearing loss but they put in implants. They do a lot of surgery that involves tumors in the skull and though the skull base. So there is also have ornithology and skull base just in Ear, nose, throat field. There are over a hundred fields. There are lots of different jobs in the doctor world. “The ENT ear nose and throat there are a lot of other specialties,” Abegtoba said. “After medical school though the work kind of comes in and that’s residency and so when you finish medical school you have to choose a specialty.” “If you go into medicine you have to decide if you want to work with your hands or not,” Abegtoba said.
When he decided he followed someone and looked at the surgeries and decided he wanted to study and train as an ENT. He also decided to do skull base and neck surgery a specialty in the ENT. After following people around all day. “We work near the brain in this very small areas they are very delicate part of a lot of fine work treating a patient and not causing a complication, so for me, like working with those complex hairs and the anatomy of it all,” Abegtoba said. Abegtoba received his undergraduate degree in microbiology. He currently not doing anything in the field of microbiology, but he still has to work with microbes.

They can see the problems using endoscopes and other high definition instruments. They have more things that help them work on the patients without affecting them that much. With machines and computer making things easier, to do produces that were a lot harder 20 to 30 years ago, some people think there should be less training for new doctors because it takes to long to produce doctors. New doctors have less to do as technology slower taking over, more people are becoming doctors and filling up the gap that was created. “So technology helps sort of drive and progress our field. I think it will play a strong role,” Abegtoba said.

BIO IN THE LAB A Chemical Messenger By: Brayan Delgadillo Splenda is a no calorie sweetener that is consumed everyday by thousands of Americans. Why doesn’t it have any calories? What is it made of? Looking at Splenda under the microscope tells a different story than looking at it out of the package. Biochemistry teaches you to see everyday things like Splenda in a different manner. Biochemistry teaches you the differences and similarities between different compounds in our everyday lives. Biochemistry is the study of chemistry inside the human body. It is more important then one might think. John Schocken, a graduate biochemistry student, who is currently teaching a biochemistry camp at the Liberal Arts and Science Academy in Austin, shares his lab experiences. “I decided to learn biochemistry because I had a really excellent experience learning about organic chemistry,” Schocken said. “When I took it I didn’t really like 15
general chemistry too much. Then I took organic chemistry because it was required for my major in college and I was actually a biology major so liking biology and having a good time in organic chemistry kind of fits together.”
then became his favorite because they allowed for a deeper understanding of molecules in the body. “I find biochemistry very helpful and it is extremely interesting,” Schocken said. Biochemistry is beneficial to everyone because it relates to the human body. Biochemistry also helps with diets and exercise by showing a regular person what makes up the food they eat and what it takes to use up the energy obtained from their meal.
“Learning biochemistry is very important to me as a biologist Picture of where the hormones are created because it allows me to in the body.

Most of Schockens goals are related to bringing biochemistry to high school students. Schockens passion brings him to share his knowledge of biochemistry with the people he encounters. “I would really like to bring some type of biochemistry or molecular biology elective to some high schools,” Schocken said. Schocken believes that preparing for college at an early stage will allow for students to be more

LIFE IN THEIR SHOES A highlight of an unrecognized career. By: Ethan Rivers In Austin last year, a tapeworm outbreak occurred in a restaurant in west Austin. It was someone’s 21st birthday and they had gathered their whole extended family for this party. Epidemiologist Janet Pichette and her team were sent to investigate. They determined after investigation that it wasn’t actually the restaurant’s food, but someone who had doubledipped at the party who had tapeworms. This is a common occurrence; an outbreak will occur and an infectious disease unit will be sent out to investigate along with the fire department and police. Epidemiologists are detectives, but of a different brand than the usual hat and trench coatwearing personal investigator. They are disease detectives. They monitor, plan for and act on different dangerous
pandemics. “It’s like being a detective in a sense,” said Janet Pichette, an epidemiologist, “Looking at data and trying to figure out what the clues are.” Like Pichette, who works for the Health and Human Services department in Austin, many people get into epidemiology just because they were interested in one facet of it. They often spend their career looking into various things that only concern them as experts. “What happens at the local level is more infectious in origin, we are working on West Nile Virus and proteus [syndrome], but we sometimes get calls about birth defect or cancer cluster investigations where we work with the state to get a handle on what those might be.” Said Janett Pichette, “we usually go to the scene with the fire and police department and
the FBI and we do our own investigation. We wanna know whose there, because we have to figure out who was exposed, it is easier to figure out who all is there, even in the first responders.” In Austin, local epidemiologists are concerned with outbreaks that happen only in Austin and the surrounding Texas area. Epidemiologists focus on outbreaks that are unique to their area of expertise or interest. Others track one disease through their career, like people working on an HIV/AIDS unit since the 80s. “In [the infectious disease] group I have the epidemiologists, disease surveillance and office of vital records,” Janet Pichette said, “When people die of disease that is how we track mortality rates.” Almost always, epidemiologists are not working alone. It is too

much of a job for just one person to undertake on their own. Working together always produces faster and more successful work. Much of what they do is impossible without help from those in their group. Working closely with the police and the fire department is also important, to plan for relief efforts or to help manage the public in times of distress. Epidemiologists work either in the field or labs. Work in labs is done for different organizations to develop vaccines and cures for dangerous diseases. Every vaccine that has ever been developed was created by an epidemiologist, a virologist, or some other type of disease professional. People planning to go into this career must take classes primarily in biology, microbiology, calculus, biochemistry and chemistry. It isn’t just about taking these classes in high school, a college degree is usually required to get a job
in this career. Mathematics is often the most important; analyzing statistics, creating graphs and writing variable equations to determine things about the disease that you are working with. “You have [to have]a strong science background, especially biology and microbiology, and it doesn’t help to have a strong chemistry and biochemistry background as well. The important thing is whether you are strong in mathematics.” Epidemiologists work with diseases from Ebola to West Nile Virus. Often the things that they work with are dangerous, even deadly. It is not common, however, for an epidemiologist to die unless he or she is working with something especially dangerous and virulent in an area without good safety and containment protocols. Sometimes if they are working in the field in places like Africa alongside doctors and medical technicians they may be in more danger. During Ebola outbreaks in West Africa there have been

doctors that have caught ill and died from the virus in the past. There is still that note of danger in any line of work where people are working with things that are exceedingly dangerous. This risk exists in almost all aspects of this career, but in the field more than in a lab. Working in the field puts you in actual contact with these people that are infected with these dangerous pandemics. A prime example is MERS. Two infected individuals traveled from London to the US last year. On the plane with them were members of Travis county, which were then quarantined along with everyone on the connecting flight they took to Austin. They have to go to extremes, because it is better to over react than under react and fail because of that. Containment of diseases is paramount in the field.
If a dangerous disease breaks out in a country without a means to contain it, other countries have to step in. It is a worldwide objective that is undertaken by many countries worldwide. Not just countries work toward the completion of this goal though, many private groups work in collaboration with organizations like the CDC and WHO to help out. Epidemiologists are very important, they tackle disastrous diseases like the Flu, Ebola, and Polio. Stopping diseases that become pandemics a feat worthy of memory. They don’t do it alone, but that still shouldn’t diminish the individual role that each of these epidemiologists plays in the lives of the people. Many may never realize the role they play in maintaining society, even though they should.
