Yannas had been studying collagen, a protein found in human skin. Teaming up during the 1970s, the two made a polymer (a chemical compound made of multiple repeating units). Using collagen fibers and a long sugar molecule, they formed a porous (full of small holes) material resembling skin.
The spleen is one of the most frequently injured intraperitoneal organs, and management of splenic injuries may require splenectomy .. The spleen is an wedge-shaped organ that lies in relation to the ninth and 11th ribs, located in the left hypochondrium and partly in the epigastrium; thus, it is situated between the fundus of the stomach and the diaphragm. The spleen is highly vascular and reddish purple; its size and weight are variable. A normal spleen is not palpable. The spleen's key function is the removal of old red blood cells "RBCs", defective circulating cells, and circulating bacteria. In addition, the spleen helps maintain normal erythrocyte morphology by processing immature erythrocytes, removing their nuclei, and changing the shape of the cellular membrane. Other functions of the spleen include the removal of nuclear remnants of RBCs, denatured hemoglobin, and iron granules ..

A hernia occurs when an organ or fatty tissue squeezes through a weak spot in a surrounding muscle or connective tissue called fascia.

Hemorrhoids (HEM-uh-roids), also called piles, are swollen veins in your anus and lower rectum, similar to varicose veins. Hemorrhoids have a number of causes, although often the cause is unknown. They may result from straining during bowel movements or from the increased pressure on these veins during pregnancy.
Scleroderma (skleer-oh-DUR-muh) is a group of rare diseases that involve the hardening and tightening of the skin and connective tissues — the fibers that provide the framework and support for your body. In some people, scleroderma affects only the skin. But in many people, scleroderma also harms structures beyond the skin — such as blood vessels, internal organs and the digestive tract. Signs and symptoms vary, depending on which structures are affected. Scleroderma affects women more often than men and most commonly occurs between the ages of 30 and 50. While there is no cure for scleroderma, a variety of treatments can ease symptoms and improve quality of life.
A brief screening examination should be conducted checking the face, eyes, mouth, chest, abdomen, spine and limbs to exclude major abnormalities. A strong cry and a widespread pink blush over the face and body are good signs that all is well. Some children may be born with ambiguous genitalia. Ambiguous genitalia is a medical emergency and requires urgent assessment by a paediatrician. If you have sufficient clinical experience, an orogastric tube should be passed when the neonate's mother has suffered polyhydramnios. This excludes oesophageal atresia.
