Angiogenesis is the process of building blood vessels. The starting and stopping of this process occurs naturally in your body by chemicals. Some of these chemicals signal cells to begin building these vessels, while others act as inhibitors, stopping the growth when necessary.
Angiogenesis is a critical function in the growth and spread of cancer in your body. Tumors require angiogenesis to be able to receive oxygen and other nutrients. Stopping angiogenesis can be achieved through a number

About Medical Technology
Medical technology is an integral of modern medicine. It is hard to think of modern medicine without advanced medical technology. Can you imagine a world without X-ray machines that help surgeons to diagnose broken bones, without sonograms that help pediatricians to make sure that babies grow normally in their mother's wombs?

In general, medical technology refers to any practical application of knowledge that aims to prolong life of patients, to reduce risk of diseases, to

Successful Treatment of Macular Degeneration With Anticancer Drugs
Vision loss from macular degeneration is caused by blood vessels that leak and create swelling under the macula. Treatment with Avastin and Lucentis, known as anti VEGF drugs which are also used to treat cancer, helps maintain vision.
Diagnosis
Macular degeneration is diagnosed by retinal specialist through examination via microscope and tests such as fluorescein angiography, which lights up leaking blood vessels, or optical coherence tomography (OCT), which shows the layers of the

Side Effects of Avastin for Eyes
Avastin (bevacizumab) is a cancer treatment, but some doctors have been prescribing it "off label," meaning they use it for disorders other than what it was created for. One of the disorders being treated with Avastin is wet macular degeneration, a disease of the retina.
Function
Wet macular degeneration is caused by the growth of abnormal new blood vessels in the eyes. Avastin works by blocking the growth of blood vessels.
Procedure
Avastin is injected directly into the affected

The Effects of a Sedentary Lifestyle
When a computer is not being used it goes into power-conserve mode. Your body shuts down in a similar fashion the moment you sit down. Lack of muscle stimulation can bring on physical and emotional complications. With the growth of technology, less activity is required on a daily basis; shopping, paying bills and social networking can all be done from behind your computer. Knowing the effects of a sedentary lifestyle may stimulate you to get up from that chair more
How to Check My Name in the National Donor Deferral Registry
The National Donor Deferral Registry (NDDR) is a database that stores the names and information of North American blood plasma donors that have been given a status of "permanently deferred" when it comes to plasma donation. The database is a self-regulation move made by the plasma collection industry to protect recipients of donated plasma from receiving plasma that is infected with Hepatitis B, C or HIV 1 or 2. The NDDR was established in 1993 and can be accessed online by all plasma donation
How to Tape Pronated Feet
Pronation is a normal motion that occurs as the foot tilts inward. Overpronation -- flat-footedness -- occurs when the arch of the foot flattens excessively. The condition can cause shin splints and plantar fascitis, which is irritation and swelling of the tissue on the bottom of the feet. You can diagnose overpronation by looking at the wear pattern on the heel areas of your shoes -- they will be worn down on the inside borders, imitating the position of your feet. You can treat overpronation
The Disadvantages of Melamine
Melamine combined with formaldehyde or urea produces a product called melamine resin. Melamine found in floor tiles, kitchenware and fire retardant fabrics is fire resistant and tolerant of high temperatures. Melamine resin, also known as thermoset plastic, begins as a white powder. Formica, made from melamine, provides a durable coating for shelving, countertops and furniture. Aside from its advantages, melamine has its share of disadvantages as well.

How to Grade a Pulse
Heart rate -- or pulse --is described in beats per minute and can be an indicator of heart health. As the heart muscle strengthens, it pumps more blood with each contraction and heart rate decreases. Blood pressure is a measurement of tension through the arteries as blood is travelling to different parts of the body. Pulse pressure is derived from the blood pressure measurement. Normal pulse pressure for an adult is 40 mmHg. Results that are higher can indicate leaky heart valves, while results

What Happens When There Is More Light in One Pupil Than the Other One?
The human eye is a complex organ. It allows us to see, interpret shapes and colors, as well as dimensions of objects. Light enters the eye and passes through many components before it gets to the optic nerve where it is eventually interpreted as a visual image.

The pupil is located in the middle of the iris, the colored disc in eyes made up of connective tissue and smooth muscle fibers. According to Dr. Ted Montgomery, the pupil is an opening that "is circular and is comparable to

How to Calculate Oxygen Tank Duration
Oxygen tanks support individuals with respiratory disorders or individuals who need continuous oxygen as a result of a temporary illness or accident. Each tank carries a finite amount of oxygen. For this reason, individuals must perform tank duration calculations to estimate the amount of time they can rely on one tank. Many factors apply when calculating duration, including variables such as safe residual levels and the conversion factors required to convert tank cylinder pressure into liters

How to Check a GFR
The glomerular filtration rate (GFR) is the flow rate of filtered fluid through the kidneys. A GFR test measures your level of kidney function and determines your stage of kidney disease. If your physician sees other symptoms that your kidneys may not be operating properly, such as high blood pressure or increased protein levels, the physician may administer a GFR. If the kidneys are not operating properly, waste products will build up in the body, causing disease. Vital organs can fail in

How to Read Hepatitis C (HCV) RNA Tests
The Hepatitis C virus (HCV) is an RNA virus that commonly causes chronic infection of the liver. The virus is blood-borne and is transmitted via blood contaminated needle puncture of the skin, such as with intravenous drug use or as may occur in an occupational accident. It may also be transmitted via blood transfusion, though this mode of transmission is rare due to careful screening of blood products. There are many serological tests for HCV infection however, tests of HCV RNA help to

How to Unstick Gauze
Gauze is used to wick moisture away from wounds and aid the healing process. Gauze keeps your wound from closing prematurely as the wound heals underneath the cut. This results in scabbing of the affected area. An unfortunate downside to using gauze is that it can adhere to the healing skin. Removing gauze takes patience, as forceful removal can reopen your wound and slow down the healing process.

How to Donate Platelets in Indianapolis, IN
Donating platelets can be a life-saving activity. These cell fragments are crucial in forming blood clots. It is important for patients suffering from cancer or who have recently gone through an organ transplant to receive platelets because they have weak immune systems and cannot form enough platelets to clot blood and repair blood vessels. Platelets can be extracted from the blood during plasma donation, or you can donate platelets separately. Platelet donation is easy and relatively

Native flying bugs are vital to Oregon's ecological balance, but they can interfere with a person's peace or a business's bottom line if the wrong one gets out of control. Many gardeners plan landscapes that attract certain flying bugs. Oregon has hundreds of butterfly enthusiasts that await the arrival of their favorite species each year.

How to Count Platelets
Platelets are small, oddly-shaped structures that float in your blood. When you are injured from a cut or internal bleeding platelets are first on the scene to make tissue repairs. They are the main agents responsible for the formation of scabs and bruises, both of which are created to thicken blood from spewing outside of blood vessels. Platelets, along with many other blood structures, are often counted during blood tests. They are measured in parts per microliter.
