A lot of people who need dentures choose to have permanent false teeth fitted. These may be either individual dental implants, or a full set of teeth secured surgically into your mouth via metal posts. These are sometimes referred to as an implant supported over denture.

Cheap dentures often look fake because of the teeth. Economy dentures are often made using PMMA (polymethylmethacrylate) for the entire denture the base and the teeth. Although PMMA is a durable material and can serve for both the base and teeth, if you look at your teeth and gums, you know how different they look naturally. Having teeth and gums of the same material inevitably makes them both look fake.

Fake teeth are false teeth options that are typically in the form of dental implants that are available through a dentist. The implants are surgically installed into your jaw bone and are a safe and logical solution to missing or broken teeth. They also cost a lot of money. The artificial teeth also keep the muscles of mustication and the dental ridge healthy if it's constructed correctly.

These are artificial so less equality than the nature need visits to the dentist to be well always needs good oral hygiene to keep the remaining natural teeth healthy& to achieve the longivity to the artificial ones… If they aren't constructed well they may cause inflammation, resorption or pain in the oral cavity. If the oral hygiene is not sufficient, bad odor will be found also.

Fake Teeth Covers

Fake Teeth Covers that hides missing chipped or cracked teeth. Original Secure Smile Cosmetic Fake Teeth Shell is made out of high quality dental acrylic and goes over existing upper teeth and gums to hide missing, chipped or cracked teeth. Custom fitting is done in the comfort of your own home, without an expensive or painful dentist visit. Once fitted properly, the Secure Smile Teeth look amazing and gums are natural in color, not a fake bright white, and have a slightly translucent appearance, like that of real tooth enamel. A dental crown is a common covering used when giving a patient various types of false tooth inserts. This tooth-shaped cap is placed over top of an existing tooth to give it the desired shape and to support other dental appliances.

Fake Vampire Teeth

Spending loads of money on vampire fangs is totally unnecessary. With fake nails, dental wax, or just a straw, you can make fake vampire teeth. Perfect teeth for perfectly horrifying look vampire fangs are the essential accessory for horror characters with an appetite for realism. The range in price speaks to range in quality: inexpensive monster teeth are simple hinged plastic inserts, while more realistic vampire teeth with "gums" are almost like dentures, while custom teeth offer the most natural fit of all. Theatrical vampire fangs and werewolf teeth are both comfortable and convincing; these fit over your own incisors and become almost a part of you.

They look real, and as a bonus, because dental putty holds them in place, you can eat, drink, and talk normally (we know how you monsters and vampires love to socialize) But for the vampire who spares no expense, and aims for the utmost realism and horror, we recommend movie quality custom designer fangs. Formulated Alpha 1 thermoplastic creates the perfect fit over your own teeth and is double chambered for superior anchoring even victims with tough hides can't knock these puppies out of line. And then there are novelty choppers. Dracula with a sense of humor always keeps a set of light-up vampire teeth.

Fake Gold Teeth

To make gold teeth, take a dental mold of your teeth, allow it to harden and then wrap gold sheeting over the mold. Warm the sheeting so that it is malleable, and create a tight impression of the molded teeth. Allow that to harden, and remove from it the dental mold. It might take some practice to create the right look, since the gold sheeting needs to be fitted at the right thickness to make it either too thick or too thin over the mold. If the gold is too thick, it might interfere with talking or eating. If it is too thin, it may not be sturdy enough to hold together inside your mouth.

How to make fake teeth that look real?

The main material used is poly morph beads which can be purchased at art supply stores. The beads are added to a glass of hot water which melts them down to a clear plastic blob that is removed from the water and then roll it into a ball with fingers. Then flatten the ball out and insert it into mouth behind back teeth. The next thing you do is bite down into the flattened material, holding it in place with your tongue, to make an impression. The key to this whole process is using a warmed butter knife (dipped frequently in the hot water) to slowly shape the teeth.

The plastic melts and allows you to mold it into the shape of teeth. For proper sizing, insert the false teeth and continue to form it with your tongue and fingers to help smooth them out and match the size and alignment to existing teeth. Once this fitting is complete, remove the false teeth and trim excess plastic with scissors while it is still soft enough to shape. Follow this up with more shaping with the warm butter knife until you are satisfied with the look and fit. These are only meant to be used as temporary false teeth.

It is a combination of different genes from different generations resulting in three main types of color, Brown, blue and green. Brown eyes is the most common color followed by blue and green. Our eye color changes as we grow older. Color can lighten as we age.

Melanin is the basic substance that determine our eye color. Newly born baby has mostly very light blue eyes, because of the fact that they have not developed melanin. Which color you see in your eyes , largely depends on your on the quantity of melanin your body have like , if your body has more melanin, you are more likely to have brown eyes. Green eyes are generally an indication of medium while blue eyes are of low melanin. Therefore it is not easy to change eye color permanently but can slightly change temporarily.

How to Change Your Eye Color

Although it’s not easy to change eye color permanently of course. You have to undergo a surgery if you are planning to change your eye color permanently. But remember, an eye is a delicate organ, therefore, you have to be careful to alter it.

Natural ways to change your eye color

Here are some methods, with help of which you can change your eye color temporarily.

Color change with your emotions

Sounds weird but true. The color of your eyes change as your mood swings. Our body produce different hormones as our state of mood changes like if you’re happy, your body produces a hormone that causes the pupil of the eye to enlarge the most vibrant eyes.

Color change with Contact lenses

To use contact lenses is the most easy and convenient way to change your eye color temporally. Blue eye color is considered as a symbol of beauty. Most celebrities usually have the blue or green eyes obtained from the use of colored contact lenses.

Color change with your diet

Yes, its effective. The food we intake is responsible for the production of hormones. There are some hormones such as norepinephrine and serotonin which are responsible for monitoring the physical response of the body’s organs. These hormones causes the expansion of pupil and expanded eyes appear lighter for some time.

• There are some foods that are more effective in this regard. Honey is generally used as a natural way to treat to the eyes. In some parts of the globe, it is still used to treat different kinds of eye allergies. Raw honey has been placed in eyes as an anti-bacterial agent. Raw Beech honeydew is one type that can work wonders in changing your eyes color.
• You can use pure honey and water to change your eye color from dark to hazel color. Simply take equal proportion of honey and light warm water and then mix until it drops in the eyes. Place two or three drops of a mixture of pure honey with water in each eye twice a day. Remember, it will take time.
• Honey can change jet-black eyes color into a medium brown and with golden light brown specs. Diluted honey is the best to use in order to lighten your eyes.
• Raw honey contains hydrogen peroxide, which is not only an antiseptic agent but naturally inhibits melanin production also. It is also used for skin bleaching purposes and help in reducing the dark pigment of the eye.
• Chemically produced or laboratory hydrogen peroxide may harm your eyes, so be careful, it can cost you eyesight.

Jakafi, also termed as ruxolitinib, works by blocking certain enzymes in the body that affect blood cell production. It is generally used to treat myelofibrosis or polycythemia vera, which are bone marrow disorders that affect your body's ability to produce blood cells. It may also be used for other purposes. It is important to note that you should not use Jakafi if you are allergic to ruxolitinib, or if you have severe kidney disease or tuberculosis. Tell your doctor if you have liver or kidney disease, if you are on dialysis, or if you are pregnant. You should not breast-feed while you are using this medicine. Grapefruit may interact with Jakafi and can affect the amount of the medication in your blood. So use this fruit after discussing with your doctor.

In order to check whether Jakafi is helping your condition and not causing harmful effects, your blood will need to be tested often. When you first start taking Jakafi, your blood will need to be tested every 2 to 4 weeks. It’s important to have follow-up visits to your doctor. Using Jakafi may increase your risk of developing skin cancer. Jakafi will harm an unborn baby or not, is still unknown.Tell your doctor if you are pregnant or plan to become pregnant while using this medcine. It is not known whether ruxolitinib passes into breast milk or if it could harm a nursing baby. You should not breast-feed while you are using ruxolitinib.

Jakafi Medication Cost, Side Effect

The person suffering from this disorder cannot control the bone marrow from the production of excessive blood cells. This results in the production of too many blood cells, which are not needed. It usually takes longer like years for Individuals with JAK2 mutation to develop a myeloproliferative disease. Nine of ten individuals with polycythemia vera have JAK2 mutation. Only half of the individuals diagnosed with essential thrombocythemia and/or primary myelofibrosis are positive for JAK2 mutation. There are other mutations in the JAK2 gene, in exons 12 and also in exons 13, which are distinct from JAK2 V617F.

There are some kind of MPNs that are most commonly associated with JAK2 mutation, including polycythemia vera (PV), where bone marrow makes too many red blood cells; essential thrombocythemia (ET), where there are too many platelet-producing cells in the bone marrow; and primary myelofibrosis (PMF), also known as chronic idiopathic myelofibrosis or agnogenic myeloid metaplasia, where there are too many platelet-producing cells and cells that produce scar tissue in the bone marrow.

JAK2 Mutation Analysis Test, Symptoms, Treatment

Here you can find all relevant information about JAK2 Mutation, such as what kind of useful health information, one can have with the help of analysis test, what kind of symptoms one can have and the available treatments are there, if you are interested then continue reading.

JAK2 Mutation Analysis Test

A JAK2 Mutational Analysis is usually recommended when a physician suspects a myeloproliferative disorder. In order to perform the JAK2 mutation test, blood sample is required, which is drawn using a syringe inserted into a superficial vein of the arm. The JAK2 mutation test is typically ordered as a follow-up test if a person has a significantly increased hemoglobin and/or platelet count and the health care provider suspects that the person may have an MPN.

Such an analysis is only helpful in providing information in both treatment and prognosis of a myeloproliferative disorder.The presence of a JAK2 mutation helps a healthcare provider make a definitive diagnosis of MPN (PV, ET or PMF). But no worries, a positive JAK2 Mutational Test does not mean that an individual is sick or will get sick. It may be only an indication of future development of polycythemia vera, or other forms of myeloproliferative disorders. But only thing that you have to take care is close follow-up with a healthcare provider.

JAK2 Mutation Analysis Symptoms

Sometimes people with MPNs may have no symptoms or a few, relatively mild ones that may be present for years before being recognized as an MPN, often during a routine physical. Following are some common symptoms such as:

• Easy bruising and bleeding
• Joint pains
• Signs and symptoms of anemia
• Unexplained weight loss
• Easy tiredness
• Headaches
• Shortness of breath
• Other heart symptoms, such as congestive heart failure
• Night sweats
• Bone and joint pain
• A pale appearance due to anemia (when red blood cells are decreased)
• Frequent infections

JAK2 Mutation Treatment

There is no single treatment that is effective for all problems that may occur due to this mutation. And even for the same disorder, there may a unique set of symptoms and circumstances that require different treatment options, as prescribed by a doctor.

Jakafi is the first drug approved by the FDA for treating MF patients. Jakafi is recommended for the treatment of patients with intermediate or high-risk myelofibrosis (MF), including primary MF, post–polycythemia vera MF and post–essential thrombocythemia MF. As a targeted therapy, Jakafi is designed to be more specific for abnormal cells.

Allogenic Stem Cell Transplantation (ASCT) is the only curative treatment for MF. Patients need to carefully discuss whether or not they may be eligible for such a procedure, due to possibility for complications. With ASCT, blood forming stem cells are transferred from a donor to the patient, essentially replacing defective stem cells with healthy ones. Before the stem cell infusion, the patient receives chemotherapy and/or radiation therapy to eradicate diseased bone marrow.

ET typically occurs due to clonal abnormality of a multipotent hematopoietic stem cell. The location where it found mostly is bimodal peaks of between ages 50 and 70 yr and a separate peak among young females. In simple words, platelet production is increased in patients. Platelet survival is usually normal, it may decrease in some cases due to splenic sequestration or, in patients with erythromelalgia, digital ischemia.Increased platelets may lead to serious bleeding.

According to some recent studies, an elevated leukocyte count is a major independent risk factor for thromboses. Bleeding is more likely with extreme thrombocytosis due to an acquired deficiency of von Willebrand factor. If someone is suffereing from such condition, bone marrow examination is strongly recommended, especially in patients with anemia, macrocytosis, leukopenia, or evidence of extramedullary hematopoiesis. The bone marrow shows megakaryocytic hyperplasia, with an abundance of platelets being released. In order to distinguish it from other myeloproliferative disorders that cause thrombocytosis, the diagnosis of ET requires a normal Hct, MCV, and iron studies.

Essential Thrombocythemia Prognosis and Treatment

If you want to knowmore about this medical condition, then keep reading.

Causes

Despite the fact that medical science is very advance now a days, still no one knows the exact causes of essential thrombocythemia (ET) or other myeloproliferative neoplasms (MPNs). Just like many other MPNs, ET is not a genetically inherited disorder, but a familial predisposition to the disease in some patients is still important. As per researchers, mutations could be a factor that alter the activity of proteins that control signaling pathways in many patients with ET. Main risk factors include:

• Gender, as discussed above, women are mostly effected,
• Age, people with an age of 60 or above are most likely to develop ET.
• Environment, as exposure to chemicals may increase an individual's risk for ET
• Mutation, unfortunately half of all ET patients have a mutation of the JAK2 gene in their blood-forming cells.
• This mutation leads to hyperactive JAK (Janus kinase) signaling, resulting in producing wrong number of blood cells.

Diagnosis

ET can be easily deducted after a routine blood test which shows that a patient has a high platelet count. Patient can experience one or more symptoms of ET and consult physician, who can determine whether a patient has ET, after performing diagnostic tests and a review of patient history and symptoms. Common tests for diagnosing ET include:

Blood Tests

Blood tests are something that the physician recommend firstly in such case. Most common tests are for iron deficiency and indicators of inflammation as well as other mimicking blood diseases.

Bone Marrow Biopsy

A bone marrow biopsy gives an insight for classical signs of ET, such as an increase in platelet precursors.

Gene Mutation Analysis

As discussed above, sometimes a gene mutation can be responsible for such a medical condition. So gene mutation test like JAK2, CALR, MPL are also common as diagnosis tool.

Symptoms

Common symptoms include:

• fatigue, or may be related to small or large vessel disturbance or bleeding.
• Headache
• Vision disturbances
• Silent migraines
• Coldness or blueness of fingers
• Burning, redness, and pain in the hands and feet
• Easy bruising, nosebleeds or heavy periods
• Blood in the urine
• Blood clotting in unusual locations, such as the abdominal veins
• Due to clotting, stroke or heart attack can also occur

Prognosis

With proper monitoring and good treatment, thrombocythemia patients usually survive. Patients have to consult regularly with a hematologist and to report any symptoms such as visual disturbances, unexplained pain, numbness, tingling or bruising. Only a small minority of people with ET may later develop acute leukemia or postpolycythemic myelofibrosis (15%), both of which can be life threatening.

Treatments

Although there is no single treatment option that can be considered appropriate or effective for all ET sufferers, as some patients are asymptomatic and require no treatment, others may require various treatments and therapies, based on the symptoms and the results of routine monitoring by a physician. Following are some commonly used treatment options for ET patients.

• In order to reduce the risk of blood clotting, low-dose aspirin is usually given to patients. It may also help relieve the burning sensation in hands or feet.
• Hydroxyurea is most common treatment that ET patients get, who are at high risk for clotting.
• Anagrelide is an excellent option for lowering platelet counts.

After conquering Syria in 332 BCE, Alexander the Great swept down into Egypt with his army. He founded Alexandria in the small port town of Rhakotis by the sea. He designed the plan for the city which was so greatly admired later by the many historians. The city has magnificent public precincts and royal palaces which cover a third of the entire area. Alexandria was the intellectual capital of the world and famous for its extensive library, which in the 3rd century BC was said to contain 500,000 volumes. Besides library, the Museum there was a center of research, with laboratories and observatories, and had scholars such as Euclid and Eratosthenes working there. Alexandria was also a center for biblical studies. The chief librarian commissioned the Septuagint, which was the oldest Greek version of the Old Testament.

Alexandria was a trading post between Europe and Asia, and famous for its easy overland connection between the Mediterranean Sea and the Red Sea. During its three earliest centuries, it was perhaps the leading cultural center of the world, home of different religions and different philosophies. It was once the center of the Hellenistic Empire, and the hub of scholarship and commerce in the ancient world. Greek scholars, Roman emperors, Jewish leaders, fathers of the Christian Church, mathematicians, philosophers, scientists, poets, and other intellectuals flocked to Alexandria. All these people were basically attracted by Alexandrian Library and Museum.

Alexandria City, Egypt

You are interested to know about different attractions of world’s great city, Alexandria. You might also be interested why and how it was once like a magnet for all intellectual people. Then continue reading, you will find the answers of all your questions.

Pharos of Aexandria

The famous Pharos Lighthouse was a welcome sight for travelers. Alexandria acted as a beacon for merchants, curious tourists, religious prophets, and most importantly, the finest intellectual minds of the times. After the fall of this great city, the great lighthouse was steadily destroyed by earthquakes as was much of the port. According to historians, Alexandria was the first city of the civilized world in terms of size, elegance, riches, and luxuries. This city had once known for everything imaginable to fill the needs of the body and soul.

This not was not only once among the greatest cities of the Mediterranean world but was a centre of Hellenic scholarship and science. It was the most attractive city for scholars, scientists, philosophers, mathematicians, artists, and historians. Eratosthenes (c.276-194 BCE) calculated the circumference of the earth to within 50 miles (80 km) at Alexandria. Euclid taught at the university there. Archimedes (287-212 BCE) the great mathematician and astronomer may have taught there and was certainly studied there. The greatest engineer and mathematician of his day, Hero (also known as Heron, 10-70 CE) was born and lived in Alexandria.

Alexander the Great

It is said that Alexander the Great had a dream as he slept one night. He had a vision in which he learned the location for his new megalopolis, and decided to make this city as a capital for his empire. He builds a new suburb beside the old town and called old and new jointly after himself, Alexandria. At that time, it was only a small fishing village but then it was a place where the humanity did live together with tolerance for one another's cultural and religious ideologies, a life of freedom.

Alexandria Library

The magnificent library of Alexandria took a long time to come into being. It begun under Ptolemy and was completed by Ptolemy II who sent invitations to rulers and scholars asking them to contribute books. No one knows how many books were held in the library at Alexandria but estimates have been made of 500,000. The city remained prosperous and continued to attract visitors from all over the world, even after the fall of Carthage following the Punic Wars (264-146 BCE), when Rome became supreme and Alexandria fell under her sway.

In 48 BCE, the increasing tensions in Rome between Julius Caesar and Pompey first impacted Alexandria negatively. Following the Battle of Pharsalus, at which Caesar defeated Pompey, Pompey fled to Alexandria seeking sanctuary and was killed by the co-regent Ptolemy XIII. Then the Caesar arrived and declared martial law. He took over the royal palace, and sent for the exiled co-regent Cleopatra VII. According to some scholars, in the civil war much of Alexandria was burned including, the famous library.

In my opinion, everyone in the safe zone seems alright so far, definitely not as strong as Rick and the survivors, but not bad either. The leader, Deanna, is leading as a tough, reasonable leader. She may be overly idealistic, but she’s fair when conflict arises. She is just irreplaceable when it’s about prompting some other members to keep peace. The walls around the place seem sturdy enough, but the residents are weak, almost untouched by the zombie apocalypse. So in this situation, it’s good for these people to trust Deanna and her people, is an important question. And the most reasonable answer is no, because it’s quite possible that someone is behind the videos Deanna took of them. Someone is pulling the strings. There’s no possible way that this place could exist.

But there is another possibility also. Alexandria could be a ludicrous accident of happenstance and good fortune. Although there’s no reason apparently that this place should exist at all, but through some strange way, they’ve survived. Maybe there is no danger in Alexandria or its denizens. The invitation of a warm bed and a warmer meal, as well as Rick and Carol and possibly others becoming too reactionary in their efforts to survive, contain some real danger.

Alexandria Safe Zone in Walking Dead

It is being said that the Season 5 premiere was titled ‘No Sanctuary, and it was actually a clue about the safety question of Alexandria. So as per that clue, Alexandria will not be safe for long.

Why Alexandria Safe Zone is not for long

As we have seen in the last Seasons, there was always a fall of the safe haven, from the quarry camp, to the CDC, to Hershel’s farm, to most memorably, the prison. So now it will be quit natural if Alexandria’s walls collapsed and the herd of bloodthirsty walkers swarmed in. The Walking Dead season is repeating the normal cycle, which begins with the heroes finding shelter at first, and when they start feeling that this shelter is the one for which they have searched for, at that moment, all falls down and many people have to die horrifically.

Now the Walking Dead group is entering Alexandria Safe-Zone, where they are going to spend much time in the comics the show is based on. The fact that just because they are in a Safe-Zone doesn't mean they are all actually safe, all viewers know. According to the comic books, three main Walking Dead characters will die in Alexandria.

If the TV show is going to follow the comic book then things are about to get super emotional in the zombie world. Yes, The Walking Dead is about to get crazy. So be ready. Alexandria is going to become a major location for everyone. Additionally, Aaron and Eric, are becoming most favorite Walking Dead couple. For the time being, they all are on their path but at the end they found each other, and most importantly Aaron found Eric.

Important Characters of Alexandria Safe Zone in Walking Dead

If you are new to this series then get a brief introduction of the most important characters of this season.

Abraham is the one, who is mainly responsible for the construction crew who ensure that the walls are safe and no zombies are getting in. Abraham and Eugene were get attacked by a group of Saviors while they are outside the walls, and a Savior named Dwight shoots Abraham in the back of the head with a crossbow.

Eric, for the time being, quite new but in coming episodes, will become an important character, not only for us but also for Aaron’s relationship. So important that he dies in Aaron’s arms.

Negan, is considered as one of The Walking Dead’s greatest villains. He is not only playing the character of brutal killer, but also wages a war against the Alexandria safe zone.

DNA is converted into messenger RNA, during transcription. Further in the process of translation, ribosomes read mRNA sequences in order to produce the amino acids that become proteins. These mRNA sequences are read in units of three nucleotide called codons. Now each codon corresponds to a single amino acid. The insertion or deletion of a nucleotide in a DNA sequence shifts the reading frame and changes how the rest of the sequence is read. As a result of this reading, different types of amino acids and proteins are produced. Here mutations may occur in multiples of three, as a consequence, another amino acid may be produced. Such type of mutations are not considered frameshift mutations because the reading frame is not altered.

A frameshift mutation is caused by an insertion or deletion of base pairs in DNA sequence, which causes a shift in the translational reading frame. Frameshift mutations have a more dramatic effect on the polypeptide as compare to other mutations. Instead of just changing one amino acid, frameshifts cause a change in all the amino acids in the rest of the gene. Because it alters the whole reading frame. In addition to frameshift mutation, there are many other types including missense, nonsense, and silent mutations all happen because of base substitutions. You can find detailed discussion about all mutations below.

Frameshift Mutation Definition with Example

Mutation is basically change in DNA sequence and it can occur in many different ways. DNA can be changed, resulting in different types of mutation.

Major types of Mutation

Following are some important types of mutations. You are now familiar with codons, as codons are discussed earlier in this article. Now let’s see how a minor switching can alter the whole code.

Substitution

It is a mutation that exchanges one base for another, in other words, it occurs only due to change in a single "chemical letter" such as switching an A to a G. Substitution can occur due to:

• change a codon to one that encodes a different amino acid and cause a small change in the protein produced.
• change a codon to one that encodes the same amino acid and causes no change in the protein produced. These are called silent mutations.
• change an amino-acid-coding codon to a single stop codon and cause an incomplete protein. Since the incomplete protein probably won't function, it could be severe effects.

Insertion

Insertions are mutations in which one or more base pairs are added to the sequence of DNA.

Deletion

Deletions are mutations in which a section of DNA is lost, or deleted. Insertions and deletions actually change the length of the DNA strand because they add or subtract one base pair from the code.

Frameshift

Since protein-coding DNA is divided into codons three bases long, insertions and deletions can alter a gene so that its message is no longer correctly parsed. Such changes are called frameshifts. That's a big deal compared to base substitutions. Insertions and deletions can have drastic effects on the DNA code and the final protein. Let's dig deeper to learn more about the consequences of these disruptive mutation types.

Example of Frameshift Mutation

In original DNA strand, the code is first transcribed into mRNA, and then it's translated into a chain of amino acids. The chain that normally cells get consists of methionine, proline, serine, and valine. Take this just an example that we required only these amino acids.That sequence makes up desired protein. Whenever an mRNA code is translated, it is being read in the letters in groups of three. If here, if we take addition case, then the DNA code would grow by one letter, and so would the mRNA code.

As a result, they all got shifted over by one. There would be five codons, but now there's one extra base. And the codons are all very different from the ones then before. In this way, the reading frames have shifted on the mRNA strand. This all happened because of a single base insertion. The effect here is called a frameshift.
That was case of an insertion. Deletion from the original DNA strand would result mRNA that contains methionine, histidine, glutamine, and phenylalanine. Once again, it's nothing like required one. 7

Gene therapy promises to help diseased tissues and organs work properly by adding a corrected copy of a defective gene. This approach is different from traditional drug-based approaches, which may treat symptoms but not the underlying genetic problems.

Gene therapy is not a molecular bandage that will mechanically fix any genetic problem. While number of disorders or medical conditions can potentially be treated using gene therapy.

What is Gene Therapy?

Gene therapy is a curative method that replaces damaged proteins by inserting the DNA for that protein into a cell.

Gene Therapy Pros and Cons

Gene therapy artificially introduces the DNA code into the cell by replacing proteins in the cell. It is different from other forms of medicine that might not introduce DNA but a chemical or protein into cells. If the specific code for making the required protein is known, it is possible to synthesize a strand of DNA in a test tube.

There are a number of DNA-delivery techniques. One general approach is to insert through un-harmful virus, which naturally inserts DNA into host cells. The virus deposits the artificial DNA into the patient's cells, and the existing cellular machinery by reading the artificial DNA code engages in protein synthesis and produces the desired protein.

Gene therapy replaces defective genes in a cell by healthy ones. Genes form the basis of heredity and come as triplets of nitrogenous basis forming amino acids. Amino acids are a composition of proteins which play an essential role in the functioning of our bodies. Hence defective genes grounds malfunctions in metabolic pathways which become diseases.

Gene Therapy treatment

Gene therapy can be classified in to two types- reproductive cell also known as germ line therapy and somatic cell therapy.

Gene Therapy Pros and Cons

Reproductive cell therapy involves replacing defective genes in reproductive cells with correct genes whereas somatic cell involves targeting somatic cells for gene replacement. Modification in the genetic makeup of somatic cells is only corrective for the patient but not inherited by offspring of the treated person.

There are some pros and cons of gene therapy given below which will help to know the in depth knowledge and scope of it in future.

Pros of Gene Therapy

Gene Therapy Pros and Cons

Replace Defective Cells
Humans have always been prone to variety of diseases; as one therapy is discovered, a new disease comes out. We are continuously hit by newer and more dangerous germs and pathogens. Though number of such diseases can be cured medically, genetic disorders have no treatment unless defective cells are replaced by appropriate one.

To replicate any protein
The production of protein that is dysfunctional makes gene therapy such an exciting field of research. Once the actual process is successfully developed, there is the potential that it could be replicated to any protein abnormality that might develop.

Gene therapy is not just for humans
Gene therapies can also apply to animals, which then facilitate to stabilize the food chain. It can also be applied to plants, eradicate diseases that can destroy entire crops.

Enhance person’s overall health
improvement of certain genes enhance the the overall health and human life span. Capable of treating a future risk of cardiovascular disease through gene therapy boost a person’s own biology, Increased muscle mass, better blood flow, and other benefits.

Cons of Gene Therapy

Transform Human Capabilities
Gene therapy can be used to improve and transform human capabilities. Certain countries experiment with this form of therapy and create unstoppable armies much like in those movies we see on the big screen.

Damage Gene Pool
Gene therapy performed to a certain degree could permanently change the human gene pool.

Increase in Disorders
Using the virus as a common vector choice is not guaranteed. There’s an exact point in the host genome where the right enzyme should be brought in and there are no guarantee that the viral enzyme responsible for this step will be able to bring in the right genes at the exact point in the host genome. Error in the process can bring about severe disorders and the body may destroy the vector perceiving it as a foreign body.

Create socioeconomic class division
In the US especially, medical care is frequently based on a person’s ability to afford that. Gene therapy is a costly process, so it may not be readily accessible to all. Eventually, if left uncontrolled, the affluent would get more affluent and the poor would just die.

The pros and cons of gene therapy prove that there is new ways for those who may be suffer from genetic disorders. With further research there is a hope of major medical breakthroughs.
