An osteosarcoma or osteogenic sarcoma is a cancerous tumor in a bone. Specifically, it is an aggressive malignant neoplasm that arises from primitive transformed cells of mesenchymal origin (and thus a sarcoma) and that exhibits osteoblastic differentiation and produces malignant osteoid.
Osteosarcomas tend to occur at the sites of bone growth, presumably because proliferation makes osteoblastic cells in this region prone to acquire mutations that could lead to transformation of cells. The tumor may be localized at the end of the long bone (commonly in the metaphysis). Most often it affects the proximal end of tibia or humerus, or distal end of femur.

2022-05-23 22:34:44 This cerebral angiogram demonstrates a berry aneurysm jutting from the top of the basilar artery of the circle of Willis at the base of the brain. Berry aneurysms arise in a weak point in the arterial wall and generally become large enough to produce symptoms in adulthood.
Berry (saccular) aneurysms are the most common type of intracranial aneurysm, representing 90% of cerebral aneurysms. Generally speaking, there is a ballooning arising from a weakened area in the wall of a blood vessel in the brain. Depending on the size of the aneurysm, their symptomatology ranges from asymptomatic to intracerebral hemorrhage (subarachnoid) in the most extreme cases.

2022-05-13 17:20:37 The biliary tract, (biliary tree or biliary system) refers to the liver, gall bladder and bile ducts, and how they work together to make, store and secrete bile. Bile consists of water, electrolytes, bile acids, cholesterol, phospholipids and conjugated bilirubin. Some components are synthesised by hepatocytes (liver cells), the rest are extracted from the blood by the liver.
Bile is secreted by the liver into small ducts that join to form the common hepatic duct. Between meals, secreted bile is stored in the gall bladder, where 80–90% of the water and electrolytes can be absorbed, leaving the bile acids and cholesterol. During a meal, the smooth muscles in the gallbladder wall contract, leading to the bile being secreted into the duodenum to rid the body of waste stored in the bile as well as aid in the absorption of dietary fats and oils by solubilizing them using bile acids.

2022-05-04 22:22:06 Skin allergy testing comprises a range of methods for medical diagnosis of allergies that attempts to provoke a small, controlled, allergic response.
During the allergy skin tests, skin is exposed to suspected allergy-causing substances (allergens) and is then observed for signs of an allergic reaction. Information from allergy tests may help doctor develop an allergy treatment plan that includes allergen avoidance, allergy shots or medications.
