What causes Osteoporosis?
What causes Osteoporosis? samer kareem 7,052 Views • 3 years ago

Bone is not a static part of the body — it's constantly being resorbed (broken down) and formed throughout your life. Your entire skeleton is replaced about every decade, according to the NIH. During your childhood and teenage years, bone formation occurs more quickly than bone resorption, resulting in growth. You reach your maximum bone density and strength around age 30, after which bone resorption slowly overtakes bone formation. Osteoporosis develops when there's an abnormal imbalance between bone resorption and formation — that is, resorption occurs too quickly, or formation too slowly.

Most scoliosis surgeons agree that children who have very severe curves (45-50° and higher) will need surgery to lessen the curve and prevent it from getting worse. The operation for scoliosis is a spinal fusion. The basic idea is to realign and fuse together the curved vertebrae so that they heal into a single, solid bone. With the tools and technology available today, scoliosis surgeons are able to improve curves significantly.

Cholesterol Removal Machine - New Invention Scott 33,987 Views • 3 years ago

An unnamed Russian scientist has introduced the concept of a device that attaches to the wall of the artery. It would first stop blood flow to the area to prevent breakaway plaque. A drill would then scrape the plaque from the artery wall. The procedure of treating plaque buildup could include bypass surgery, stent replacement and balloon angioplasty. Since the plaques are of different types and locations in the body, the inventor proposed using different types of cutting mills.

Atrial Septal Defect
Atrial Septal Defect samer kareem 7,513 Views • 3 years ago

atrial septal defect (ASD) is a hole in the wall between the two upper chambers of your heart (atria). The condition is present from birth (congenital). Small atrial septal defects may close on their own during infancy or early childhood. Large and long-standing atrial septal defects can damage your heart and lungs. Small defects may never cause a problem and may be found incidentally. An adult who has had an undetected atrial septal defect for decades may have a shortened life span from heart failure or high blood pressure that affects the arteries in the lungs (pulmonary hypertension). Surgery may be necessary to repair atrial septal defects to prevent complications
