This rare, potentially life-threatening syndrome is typically caused by an angle of 6–25° between the AA and the SMA, in comparison to the normal range of 38–56°, due to a lack of retroperitoneal and visceral fat (mesenteric fat). In addition, the aortomesenteric distance is 2–8 millimeters, as opposed to the typical 10–20. [1]
Spinal muscular atrophy (SMA) is a rare neuromuscular disorder that results in the loss of motor neurons and progressive muscle wasting. [3] [4] [5] It is usually diagnosed in infancy or early childhood and if left untreated it is the most common genetic cause of infant death. [6]
Nusinersen, [7] marketed as Spinraza, [4] is a medication used in treating spinal muscular atrophy (SMA), a rare neuromuscular disorder. [8] [4] In December 2016, it became the first approved drug used in treating this disorder.
The stomach is a muscular, hollow organ in the upper gastrointestinal tract of humans and many other animals, including several invertebrates.The stomach has a dilated structure and functions as a vital organ in the digestive system.
The supplementary motor area (SMA) is a part of the motor cortex of primates that contributes to the control of movement. It is located on the midline surface of the hemisphere just in front of (anterior to) the primary motor cortex leg representation. In monkeys, the SMA contains a rough map of the body. In humans, the body map is not apparent.
[5] The term inflammation is not a synonym for infection . Infection describes the interaction between the action of microbial invasion and the reaction of the body's inflammatory response—the two components are considered together in discussion of infection, and the word is used to imply a microbial invasive cause for the observed ...
The pH level is maintained by the proton pump H + /K + ATPase. [2] The parietal cell releases bicarbonate into the bloodstream in the process, which causes a temporary rise of pH in the blood, known as an alkaline tide. The gastric juice also contains digestive enzymes produced by other cells in the gastric glands – gastric chief cells.
It is the innermost layer of the stomach. [5] It is affected by the hormone histamine, which signals it to release hydrochloric acid (HCl). Sub-mucosal layer – This layer consists of different vessels and nerves, ganglion neurons, and adipose tissue. It is the second layer of the stomach and supports the mucosa. [6]
