Atrophic gastritis is a process of chronic inflammation of the gastric mucosa of the stomach, leading to a loss of gastric glandular cells and their eventual replacement by intestinal and fibrous tissues. As a result, the stomach's secretion of essential substances such as hydrochloric acid, pepsin, and intrinsic factor is impaired, leading to ...

Dorsal pancreatic agenesis is a congenital anomaly characterised by the absence of the duct of Santorini, tail and body of the pancreas. [1] It is regarded as asymptomatic and the most common clinical manifestation is non-specific abdominal pain. [2] While the cause is unclear, its mechanism is thought to be impaired dorsal buds or mutation of ...
Cerebral atrophy is a common feature of many of the diseases that affect the brain. [ 1] Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them. Brain atrophy can be classified into two ...
