".../2018" /> <meta itemprop="description" content="Food and liquid pass from the mouth to the stomach through a muscular tube called the esophagus. Sometimes, the cells of the esophagus become cancerous. When the cells of the esophagus divide without order or control, it is called esophageal cancer. There are two types of esophageal cancer: squamous cell cancer and adenocarcinoma. The lining of the esophagus is made up of flat, thin cells called squamous cells. Squamous cell cancer develops in the upper and middle part of the esophagus. In addition to the squamous cells, the esophagus contains glandular cells. The glandular cells make and release mucus and other fluids that help with digestion. If stomach acids back up into the lower part of the esophagus, the acids may irritate the glandular cells causing the cells to change. These changes can lead to cancer in glandular cells, called adenocarcinoma. Symptoms of esophageal cancer include difficulty swallowing, severe weight loss, pain in the throat, back, or behind the breastbone, vomiting, or hoarseness. Esophageal cancer can spread (metastasize) to other organs in the body. Surgery is the most common treatment for either type of esophageal cancer. Radiation and chemotherapy may also be used. New types of treatments, such as laser therapy and photodynamic therapy may be used to ease symptoms. New immunotherapy agents can also target the tumor cells. The immune system is an important line of defense against tumors. Cancerous tumors are made up of many abnormal cells that multiply faster than normal. This causes them to grow into masses that can be malignant. Because they are abnormal, the molecules they produce, called antigens, do not match the molecules that normal cells make. When immune cells capture these antigens, they recognize that they are different and possibly a threat, which causes them to seek out other immune cells in the body. It will find a specific white blood cell and show it the captured antigen. The white blood cell has special receptors on its surface that allow it to remember this potential threat. It is activated and ready to attack any cells that have that specific antigen on its surface. Many activated white blood cells are recruited and travel to the tumor to defend the body. When the white blood cell arrives at a tumor cell, it binds to the surface to check whether or not it is a threat. If it recognizes the antigen, that is a signal for the white blood cell to attack the abnormal cell and kill it. More recruited white blood cells help to destroy the tumor, one cell at a time. The white blood cells have an off-switch receptor to prevent them from attacking normal, healthy cells in the body. Because the immune system is so efficient, it is important that it does not begin turning against the body’s own cells by mistake. Normal cells that might otherwise be targeted by white blood cells can bind to the receptor with ligands that send a stop signal and act as a safety checkpoint to turn off the white blood cell before it attacks. When the receptor binds to its ligands on these cells, it will read it as familiar, even if there are unfamiliar antigens on the surface. However, some tumor cells can use this safety checkpoint to their advantage. They display a lot of the two matching ligands. The amount of these ligands creates a stop signal so strong that when the receptor binds to them, the white blood cell mistakes the tumor cell as healthy and normal, even if it sees the abnormal antigen. This acts like an off-switch and the white blood cell will stop attacking. In a tumor, many of the abnormal cells may be able to avoid detection this way. This results in the immune system no longer recognizing the threat, so the tumor will continue to grow. Monoclonal antibodies are a type of therapy and are made to stick to a specific molecule. In this case, the monoclonal antibody is designed to bind to the misleading markers on the surface of the tumor cell. When the white blood cell binds, it no longer recognizes those off-switch markers—it only recognizes the abnormal antigen. This blocks the tumor cell’s attempt to hide and allows the white blood cell to remain activated. Now that the white blood cell recognizes that the tumor cell is a threat to the body, it will attack and destroy it. As more tumor cells are destroyed, this can stop the spread of cancer by reducing metastatic growth in your body. Your doctor will be able to scan your body to see the improvement. " /> <h3..."

".../2018" /> <meta itemprop="description" content="The lungs are the primary organ in respiration. They are sponge-like organs that are divided into lobes. Although the right lung has three lobes, the left lung has only two lobes due to the position of the heart, which is toward the left side of the body. During respiration, air travels through the nose, down the trachea or windpipe, and into the bronchus. The bronchus branches into narrower bronchioles and then into smaller and smaller airways ending in air sacs called alveoli. It is at the alveoli that oxygen is exchanged for carbon dioxide. Most cancerous changes occur in the lungs long before any symptoms are present. There are many types of lung cancer, but the most common lung cancer is bronchogenic carcinoma, which begins as a tumor in the lining of the bronchi. Lung cancer can also be present in the trachea, the bronchioles, or the alveoli. Lung cancer is the leading cause of cancer deaths among men and women, but the most alarming news is that more women will die from lung cancer than will die from breast cancer. Cigarette smoking poses the greatest risk for developing lung cancer. The lymphatic system provides the perfect harbor for cancers to travel throughout the body. This is called metastasis. Using diagnostic images, like CT scans or MRI, your doctor can scan your body to see if cancer has metastasized. This means cancer has spread to other parts of your body and is beginning to replicate there. One of the most important parts of a cell is the DNA contained in the nucleus. DNA makes up the cellular instructions for life and heredity; the entire genetic code is written into these double helix molecules. When cells in the body replicate, they first create a second copy of their DNA so that when they divide, both new cells have a full set of DNA. Healthy cells only replicate as needed. Cancer cells, however, do not stop dividing on their own. They grow into masses without any limit or control. These masses of abnormal cells can become malignant tumors. Some drugs, like carboplatin, target the growth of cancer cells by binding to the strands of DNA. When the drug forms this bond with the DNA, the DNA can become misshapen so that the cell can no longer read the code. If the cell cannot read the genetic instructions to live, it will die instead of growing. This can stop spread of cancer by reducing the metastatic growth in your body.

".../2018" /> <meta itemprop="description" content="The female breast is primarily composed of fatty tissue and mammary glands. Mammary glands drain into the lactiferous ducts, which connects them to the nipple. During pregnancy, mammary glands swell in order to accommodate milk production. This process is regulated by hormones. Breast cancer is a malignant neoplasm of the mammary gland. It is one of the most common causes of cancer fatality in women. Early detection through regular breast self-examination and mammography is key. Through self-examination irregularities, such as lumps or masses, can be detected before the disease has had a chance to spread. The danger associated with all cancer, but especially with breast cancer, is that the disease can travel quickly once it has invaded the lymphatic system. The lymphatic system provides the perfect harbor for cancers to travel throughout the body. This is called metastasis. Using diagnostic images, like CT scans or MRI, your doctor can scan your body to see if cancer has metastasized. This means cancer has spread to other parts of your body and is beginning to replicate there. When cells in the body replicate, they go through a process of division. Normal cell division is controlled by microtubules that pull apart the chromosomes. Healthy cells only replicate as needed. Cancer cells, however, do not stop dividing on their own. They grow into masses without any limit or control. These masses of abnormal cells can become malignant tumors. Some drugs, like Paclitaxel, target the growth of cancer cells by stopping them from replicating. The drug interacts with the microtubules of the dividing cells and stops them from finishing the separation of the chromosomes. The cell cannot divide properly and will die instead of growing.

".../2017" /> <meta itemprop="description" content="The heart is a muscle that contracts in rhythmic sequence for the duration of our lifetime. Each beat is stimulated by an electrical signal that is generated by the heart&#39;s conduction system. A normal heart beats 60 to 100 times per minute. Sometimes, a problem with the conduction system causes the heart to beat too fast, too slow, or to have an erratic or irregular beat. A test, called an electrocardiogram, or EKG, can measure and record the heart&#39;s electrical activity. In a normal heartbeat, the heart&#39;s signal follows a specific pathway through the heart. The signal begins in the sino-atrial node, or SA node, located in the right atrium. The SA node triggers the atria to contract, pushing blood into the ventricles. The electrical signal then travels through the atrio-ventricular node, or AV node, and into the ventricles. This signal now causes the ventricles to contract, pumping blood to the lungs and body. Atrial fibrillation is a type of arrhythmia, or abnormal heartbeat, that is caused by erratic electrical signals originating from the atria. During this rhythm disturbance, the normal, coordinated contractions between the atria and ventricles become compromised, interfering with the hearts ability to efficiently deliver blood to the body. In people who experience atrial fibrillation, many rapid electrical impulses originating from different areas of the heart are sent to the atria. These impulses cause a very fast and chaotic rhythm. Because of this rhythm, the contractions of the atria become erratic. As a result, the irregular contractions of the atria do not properly fill the ventricles with blood, causing the ventricular contractions to also become erratic. The heart rate may increase to 100 to 175 beats per minute or more. Atrial fibrillation can cause fainting, weakness, and may lead to blood clots. These blood clots form because, when your heart does not beat right, blood has trouble flowing and will pool in certain areas. When blood pools, it gets sticky and thick, which can lead to the formation of blood clots. Clots can break off and travel in the blood stream and, in some cases, get stuck and block blood flow from reaching important parts of your body. One way to prevent clotting and the problems that arise from it is to take warfarin as your doctor prescribes. Blood clots occur in two ways. First, platelets activate and become sticky against the heart wall. Second, strands of protein called fibrinogen become connected as fibrin and tangle in the platelets to help them clump together. Fibrinogen is activated to form fibrin through a long cascade of chemical reactions. In the presence of vitamin K, fibrinogen is activated to form fibrin. This causes vitamin K to become inactive. Vitamin K must bind to an enzyme for it to be used again. However, Warfarin binds to this enzyme and prevents it from binding to Vitamin K. When this happens, vitamin K can no longer activate fibrinogen. Without renewed vitamin K, this stops the clotting process. Always remember to take warfarin as prescribed and to be tested as your doctor recommends to assure that you avoid complications and have proper anticoagulation for your atrial fibrillation." /> <h3..."

".../2017" /> <meta itemprop="description" content="During the digestive process, much of the food that is eaten is converted into glucose, commonly known as blood sugar. Glucose circulates in the bloodstream and is used as food for the body&#39;s cells. But the cells cannot absorb glucose without help. A hormone called insulin, which is produced in the pancreas, must first bind to a cell’s surface. When this occurs, the body’s cells are then able to absorb the glucose, which returns the body’s blood sugar to a normal, healthy level. When your body doesn’t produce enough insulin or when your body isn’t able to properly use the insulin that it does produce, you can develop diabetes. Diabetes mellitus is a disorder that affects the body&#39;s ability to efficiently use blood glucose. There are two different types of diabetes. In Type 1 diabetes, the pancreas does not produce any insulin, so glucose cannot be absorbed to refuel the cells. In Type 2 diabetes, insulin is produced, but it does not work properly and the glucose is not absorbed consistently by the cells. When this happens, it means your body’s cells are starving for food. If left untreated, diabetes increases your risk of heart disease, stroke, kidney damage, or blindness. Wounds may take longer to heal, you may develop skin disorders or foot problems that may even require amputation. The good news is that diabetes can be managed with diet, exercise, and medication. Many medications are used to manage both types of diabetes. Metformin is a drug used to treat Type 2 diabetes. It can be taken as a pill with food. These drugs help insulin work better to control blood sugar in your intestines, liver, and muscles in three ways. First, the drugs stop your digestive system from absorbing as much glucose. When food is broken down in the intestines, only part of the glucose available is absorbed into the blood stream. The second way Metformin works is to stop the liver from producing too much glucose. When glucose production in the liver reaches a more normal rate, there is less excess glucose in the blood stream. The third way occurs in skeletal muscle cells. Cells have trouble absorbing glucose because insulin does not work properly, but the drug works to activate an alternate pathway that allows glucose to come into the cell. This allows your body to properly absorb glucose from the bloodstream. By regulating glucose uptake by the intestines, glucose output by the liver, and glucose absorption by the cells, Metformin is an effective drug for Type 2 diabetes. Diabetes is a disease where you don’t necessarily feel bad—but bad things can be going on in your body if you let diabetes go untreated. Minimize your risk of diabetes-related complications such as heart or kidney disease, blindness or foot disorders by eating right, not smoking, exercising regularly and making sure to keep taking the medication your doctor prescribed for you." /> <h3..."

".../2017" /> <meta itemprop="description" content="The brain is composed of millions of interconnecting nerve cells called neurons. In order for a person to think, move, or feel, these neurons must communicate with one another. They do so by sending and receiving chemical messengers called neurotransmitters. When a neurotransmitter is released from a neuron, it crosses a cleft, or synapse, and binds to a receptor on another neuron; thus the signal is passed on. When a person experiences a traumatic event, the body responds through a release of hormones and neurotransmitters in order to cope with the situation. Most of the time, the person can recover from this experience normally, but in some cases, people continue to experience fear long afterwards. This is called Posttraumatic Stress Disorder. Posttraumatic Stress Disorder (PTSD) is a condition that occurs when a person continues to respond to a traumatic event long after it has ended. It can be experienced in the short term or become an ongoing condition. There is evidence that people with PTSD have abnormal activity in certain parts of the brain that are connected to memories, fear response, and emotions. Abnormal levels of neurotransmitters can also cause symptoms, triggering a fear response and other symptoms because of this imbalance. Symptoms of PTSD may include flashbacks or bad dreams related to the event, difficulty sleeping, avoidance of things that relate to the event, changes in mood or numbness, and living in a state of agitation or fear. Antidepressant medications and psychotherapy may be prescribed to treat some patients with this condition. Psychotropic drugs work by changing the amounts of one or more of the neurotransmitters in the brain. This can be done by stopping or increasing their actions. For example, Selective Serotonin Reuptake Inhibitors, or SSRIs, can be used to treat PTSD. These drugs slow down or stop the process of serotonin being reused by the neurons by blocking the reuptake pumps. By decreasing the amount of serotonin that is recycled, an increased amount of serotonin remains in the gap. This allows more serotonin to be available in order to pass on the next signal between the neurons. When the amount of serotonin in the brain is normal, symptoms of PTSD may improve. The prescribing and monitoring of medications for PTSD is complex and requires assessment of many different aspects of a patient&#39;s history and current symptoms. Management of serious disorders such as PTSD is different for everyone. If you show symptoms of PTSD, consult with a psychiatrist about the best treatment options for you." /> <h3..."

The Zika virus is typically spread to humans through contact with mosquitoes. The mosquito species that transmit the Zika virus have distinct black and white markings and bite during the day. When a mosquito bites, it punctures through the skin to access a blood vessel. The virus leaves the salivary glands and enters into the bloodstream. Symptoms include fever, rash, joint pain, and red eyes. These symptoms can last up to a week. A person may not realize they are infected with the Zika virus because often times the symptoms are mild or, in some cases, don’t exist. Yet the Zika virus remains a serious concern for pregnant women because the virus can pass from the mother to the fetus. A fetus that contracts the virus is at risk for brain defects, including microcephaly. Microcephaly is a condition that occurs when the brain develops abnormally and results in a small head. The virus stays in the body for only a few weeks. After the body destroys the virus, there are no longer symptoms or risks and the person may be immune to future Zika infections.

After a person has had chickenpox, the virus can remain inactive in the nerve tissue for many years. Stress, aging and diseases that weaken the immune system can cause the virus to become active. When the virus is activated, inflammation and pain develop along the sensory nerve pathways, called dermatomes, and on the skin overlying the dermatome. Shingles, or herpes zoster, usually starts with a tingling sensation along the dermatome. A painful skin rash develops in 2-3 days. The rash often appears as a strip or band on one side of the body in the area of the dermatome. Other common locations for the rash include the side of the neck or face. The rash is usually followed by small, pus-filled blisters that will break open and eventually crust over. These symptoms last about 2 – 4 weeks. A condition called postherpetic neuralgia is a complication of shingles. For some people, the nerves affected by shingles become damaged and continue to send pain signals to the brain long after the rash has healed. Shingles is not contagious. The majority of patients who develop shingles are over the age of 50. Treatment may include antiviral medication and pain medication. A shingles vaccine is recommended for people over age 60.

The Zika virus is typically spread to humans through contact with mosquitoes. The mosquito species that transmit the Zika virus have distinct black and white markings and bite during the day. When a mosquito bites, it punctures through the skin to access a blood vessel. The virus leaves the salivary glands and enters into the bloodstream. Symptoms include fever, rash, joint pain, and red eyes. These symptoms can last up to a week. A person may not realize they are infected with the Zika virus because often times the symptoms are mild or, in some cases, don’t exist. Yet the Zika virus remains a serious concern for pregnant women because the virus can pass from the mother to the fetus. A fetus that contracts the virus is at risk for brain defects, including microcephaly. Microcephaly is a condition that occurs when the brain develops abnormally and results in a small head. The virus stays in the body for only a few weeks. After the body destroys the virus, there are no longer symptoms or risks and the person may be immune to future Zika infections.

Asthma affects 3 to 5 percent of adults and 7 to 10 percent of children. Severe asthma attacks cause tens of thousands of deaths per year. Three changes occur inside the airways of the lungs in people with asthma: the first change is inflammation, or swelling, whereby the airway becomes inflamed and produce a thick mucus. Inflammation then leads to constriction of the muscles around the airways, causing the airways to become narrow. This narrowing is also referred to as bronchospasm. The third change is increased sensitivity of the airways, causing the asthma patient to become overly sensitive to animal dander, pollen, cold air and tobacco smoke, to name a few.

Many people with diabetes take insulin to keep their blood sugar at a normal, healthy level. There are several methods of insulin delivery including: syringe, pen, jet injector, and pump. The most common type of insulin delivery is through a syringe. An insulin dose is drawn up into the syringe from a vial and injected directly into the skin. The syringe should be disposed of in a puncture-proof &quot;sharps&quot; container designed for medical waste. Insulin pens contain pre-filled cartridges of varying doses which are injected directly into the skin. A jet injector does not use a needle to inject insulin. Instead, a high-pressure air mechanism is used to push a fine spray of insulin into the skin. Each of these methods of insulin delivery can be used to inject insulin in several areas of the body including the thighs, hips, abdomen, and upper arms. They are usually used several times a day. However, an insulin pump delivers insulin continuously throughout the day and can be worn on a belt or in a pocket. Insulin pumps allow people to more tightly control their glucose levels. No matter which method of insulin delivery is chosen, it is important that a person with diabetes still checks their blood sugar 3 - 4 times a day." /> <h3..." Line: 1708 Column: 1 - 20
