Osteoblas

Osteoblast: A cell that makes bone. It does so by producing a matrix that then becomes mineralized. Bone mass is maintained by a balance between the activity of osteoblasts that form bone and other cells called osteoclasts that break it down

Central core disease of muscle

Central core disease of muscle: One of the conditions that produces 'floppy baby' syndrome. CCD causes hypotonia (floppiness) in the newborn baby, slowly progressive muscle weakness, and muscle cramps after exercise. Muscle biopsy shows a key diagnostic finding (absent mitochondria in the center of many type I muscle fibers). CCD is inherited as a dominant trait. The CCD gene is on chromosome 19 (and involves ryanodine receptor-1).

Fever of Unknown Origin

Fever of Unknown Origin: Fever of unknown origin (FUO) is a fever greater than 38.3°C (101 °F) that has occurred intermittently for over three weeks, for which no specific cause readily identified.
In 85 to 95% of cases, the specific cause for a fever of unknown origin can eventually be identified after extensive diagnostic testing. The causes of a fever of unknown origin that are eventually discovered typically fall into one of three categories: uncommon infections, cancers, and chronic inflammatory diseases (most commonly connective tissue diseases or autoimmune diseases).

G6PD deficiency

G6PD deficiency: Deficiency of the enzyme glucose-6-phosphate dehydrogenase (G6PD), the most common enzyme defect of medical importance. About 10 percent of American black males have G6PD deficiency, as do a lesser percent of black females. G6PD deficiency is also increased in frequency in people of Mediterranean origin (including Italians, Greeks, Arabs, and Jews). The gene encoding G6PD is on the X chromosome. Males with this enzyme deficiency may develop anemia due to the breakup of their red blood cells when they are exposed to oxidant drugs, naphthalene moth balls, or fava beans. The offending drugs include the antimalarial primaquine, salicylates, sulfonamide antibiotics, nitrofurans, phenacetin, and some vitamin K derivatives. Fever, viral and bacterial infections, and diabetic acidosis can also precipitate a hemolytic crisis (when the red blood cells break up), resulting in anemia and jaundice. The concentration of G6PD deficiency in certain populations is believed to reflect a protective effect it afforded (much like sickle cell trait) against malaria.

Palmitate

Palmitate: An antioxidant and a vitamin A compound that is added to low-fat and fat-free milk to replace the vitamin content lost through the removal of milk fat. Palmitate (more formally known as retinyl palmitate) contains palmitic acid, a 16-carbon saturated fatty acid, which is the major fatty acid found in palm oil. The palmitic acid is attached to the alcohol form of vitamin A, called retinol, to make vitamin A stable in milk. The name "palmitate" comes from the French "palmitique" from palmite, the pith of the palm tree.

Stereotactic surgery

Stereotactic surgery: Surgery in which a system of three- dimensional coordinates is used to locate the site to be operated on. Stereotactic surgery is used in neurosurgery (and neurological research) for locating points within the brain. This is usually done by using an external, three-dimensional frame of reference ****d on the Cartesian coordinate system. A stereotactic needle biopsy is a biopsy in which the spot to be biopsied is located three-dimensionally, the information is entered into a computer, and the computer calculates the information and positions a needle to remove the biopsy sample

Knock-knees

Knock-knees: An abnormal curve of the legs that causes the knees to touch or nearly touch while the feet are apart. The problem may arise in the bone structure itself, or in some cases it develops gradually as a result of muscle abnormalities. Knock- knees can cause movement difficulties, muscle and bone strain, and pain from overstress on the ankles. The condition can be helped via physical therapy, and in some cases corrected with surgery. Also called genu valgum
