Retinoblastoma samer kareem 1,384 Views • 3 years ago

Retinoblastoma is an eye cancer that begins in the retina — the sensitive lining on the inside of your eye. Retinoblastoma most commonly affects young children, but can rarely occur in adults. Your retina is made up of nerve tissue that senses light as it comes through the front of your eye. The retina sends signals through your optic nerve to your brain, where these signals are interpreted as images. A rare form of eye cancer, retinoblastoma is the most common form of cancer affecting the eye in children. Retinoblastoma may occur in one or both eyes.

Cystinuria
Cystinuria samer kareem 1,390 Views • 3 years ago

Cystinuria is a condition characterized by the buildup of the amino acid cystine, a building block of most proteins, in the kidneys and bladder. As the kidneys filter blood to create urine, cystine is normally absorbed back into the bloodstream. People with cystinuria cannot properly reabsorb cystine into their bloodstream, so the amino acid accumulates in their urine. As urine becomes more concentrated in the kidneys, the excess cystine forms crystals. Larger crystals become stones that may lodge in the kidneys or in the bladder. Sometimes cystine crystals combine with calcium molecules in the kidneys to form large stones. These crystals and stones can create blockages in the urinary tract and reduce the ability of the kidneys to eliminate waste through urine. The stones also provide sites where bacteria may cause infections.

Epstein–Barr Virus samer kareem 1,890 Views • 3 years ago

The virus was first discovered in 1964 when Sir Michael Anthony Epstein and Ms. Yvonne Barr found it in a Burkitt lymphoma cell line. In 1968, the virus was linked to the disease infectious mononucleosis. Infection with Epstein-Barr virus (EBV) is common and usually occurs in childhood or early adulthood. EBV is the cause of infectious mononucleosis (also termed "mono"), an illness associated with fever, sore throat, swollen lymph nodes in the neck, and sometimes an enlarged spleen. It is also known as human herpes virus 4. Although EBV can cause mononucleosis, not everyone infected with the virus will get mononucleosis. Less commonly, EBV can cause more serious disease. Symptoms caused by EBV are usually mild and self-limited, but the virus persists in the body for life. It can be reactivated quietly without causing symptoms and may contaminate saliva. Thus, otherwise healthy people can spread the virus to uninfected people through kissing or sharing

Insulin
Insulin samer kareem 1,713 Views • 3 years ago

Insulin is a hormone made by the pancreas that allows your body to use (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia). The cells in your body need sugar for energy. However, sugar cannot go into most of your cells directly. After you eat food and your blood sugar level rises, cells in your pancreas (known as beta cells) are signaled to release insulin into your bloodstream. Insulin then attaches to and signals cells to absorb sugar from the bloodstream. Insulin is often described as a “key,” which unlocks the cell to allow sugar to enter the cell and be used for energy.
