Gastric Bypass
Gastric Bypass samer kareem 20,385 Views • 3 years ago

Gastric bypass is surgery that helps you lose weight by changing how your stomach and small intestine handle the food you eat. After the surgery, your stomach will be smaller. You will feel full with less food. The food you eat will no longer go into some parts of your stomach and small intestine that absorb food. Because of this, your body will not get all of the calories from the food you eat.

Acute sinusitis can be triggered by a cold or allergies and may resolve on its own. Chronic sinusitis lasts up to eight weeks and may be caused by an infection or growths. Symptoms include headache, facial pain, runny nose, and nasal congestion. Acute sinusitis usually doesn't require any treatment beyond symptomatic relief with pain medications, nasal decongestants, and nasal saline rinses. Chronic sinusitis may require antibiotics.

Ventricular Septal Defect
Ventricular Septal Defect samer kareem 9,822 Views • 3 years ago

A ventricular septal defect (VSD) is an opening or hole in the wall that separates the two lower chambers of the heart. This wall is called the ventricular septum. The hole causes oxygen-rich blood to leak from the left side of the heart to the right side. This causes extra work for the right side of the heart, since more blood than necessary is flowing through the right ventricle to the lungs. The hole is usually closed with surgery. However, in certain situations, your child's cardiologist and surgeon may think it is best to close the hole with a special device. This procedure is done in the heart catheterization lab.

Diabetes Pathophysiology
Diabetes Pathophysiology samer kareem 6,430 Views • 3 years ago

When food is taken, it is broken down into smaller components. Sugars and carbohydrates are thus broken down into glucose for the body to utilize them as an energy source. The liver is also able to manufacture glucose. In normal persons the hormone insulin, which is made by the beta cells of the pancreas, regulates how much glucose is in the blood. When there is excess of glucose in blood, insulin stimulates cells to absorb enough glucose from the blood for the energy that they need. Insulin also stimulates the liver to absorb and store any excess glucose that is in the blood. Insulin release is triggered after a meal when there is a rise in blood glucose. When blood glucose levels fall, during exercise for example, insulin levels fall too. High insulin will promote glucose uptake, glycolysis (break down of glucose), and glycogenesis (formation of storage form of glucose called glycogen), as well as uptake and synthesis of amino acids, proteins, and fat. Low insulin will promote gluconeogenesis (breakdown of various substrates to release glucose), glycogenolysis (breakdown of glycogen to release gluose), lipolysis (breakdown of lipids to release glucose), and proteolysis (breakdown of proteins to release glucose). Insulin acts via insulin receptors.

Deviated nasal septum
Deviated nasal septum samer kareem 1,633 Views • 3 years ago

A deviated septum occurs when the thin wall (nasal septum) between your nasal passages is displaced to one side. In many people, the nasal septum is displaced — or deviated — making one nasal passage smaller. When a deviated septum is severe, it can block one side of your nose and reduce airflow, causing difficulty breathing. The additional exposure of a deviated septum to the drying effect of airflow through the nose may sometimes contribute to crusting or bleeding in certain individuals. Nasal obstruction can occur from a deviated nasal septum, from swelling of the tissues lining the nose, or from both. Treatment of nasal obstruction may include medications to reduce the swelling or nasal dilators that help open the nasal passages. To correct a deviated septum, surgery is necessary.

How is HIV Transmitted?
How is HIV Transmitted? samer kareem 1,545 Views • 3 years ago

-Almost all the cases of occupational transmission of HIV have been due to transmission via exposure to blood and certain body fluids. The body fluids wherein standard precautions have been recommended include semen, vaginal secretions, and any other body fluid containing visible blood. Other standard precautions, according to the Center for Disease Control and Prevention (CDC), also apply to cerebrospinal, peritoneal, pleural, pericardia!, synovial fluid, or any other tissue, even though the epidemiologic data regarding the risk of HIV transmission from these fluids is insufficient. Standard precautions do not apply to urine, sweat, tears, sputum, vomitus, and nasal secretions or feces, as long as there is no gross visible blood. The occupational transmission of HIV has never been documented from the above sources.

A nephron (from Greek νεφρός (nephros) meaning "kidney") is the basic structural and functional unit of the kidney. Its chief function is to regulate the concentration of water and soluble substances like sodium salts by filtering the blood, reabsorbing what is needed and excreting the rest as urine.

How To Increase Brain Power, How To Increase Brain Activity, How To Boost Your Concentration--- http://brain-revitalizer.info-pro.co --- Improve Concentration, Ask anyone today what they have a hard time with and more often than not they are likely to cite trouble focusing or concentrating. With laptops, smart phones, television, GPS systems and social media, it is hard to block out all the distractions when you need to focus on something specific. Attention deficit disorder may be one of the most popular excuses for our lack of concentration, but it's not an entirely accurate diagnosis since many of us simply aren't training our brains the right way to improve our focus. Concentration is necessary just to make it through a typical workday. From driving and working to shopping and cooking, focus is essential in order to get tasks accomplished. Unfortunately many of us have a hard time zoning in on a specific project and seeing it through to completion. Being easily distracted is not necessarily a disorder but it will keep you from managing your time wisely and getting done the important things that need your attention. There are several ways people can improve their concentration, including strategic brain games and exercises, along with guided meditation and brainwave entrainment. Research has shown that the more a person trains their brain in specific skill sets, the better one can get at cognitive thinking, problem solving and memorization. Using computer generated pulses, or isochronic tones, during brain entrainment meditation is another way to synchronize your brain's frequencies so you can operate on a fast or slow frequency that will assist in achieving states of productivity or relaxation. As we all know, when we are relaxed our concentration and decision making are much better than if we are under stress or hurried. Being able to tap in to specific Alpha, Theta and Delta waves allows us to synchronize our brainwaves with sound pulses so we can be more focused on specific projects and tasks. But YOU can be different! You can use Genius Brain Power to empower your brain so that you come alive with more energy, learn quicker, think more creatively, focus on your work like never before and drastically reduce stress with amazingly deep states of relaxation and meditation. click here: http://brain-revitalizer.info-pro.co
