seriová extrakce

The selective extraction of deciduous teeth during the stage of mixed dentition in accordance with the shedding and eruption of the teeth. It is done over an extended period to allow autonomous adjustment to relieve crowding of the dental arches during the eruption of the lateral incisors, canines, and premolars, eventually involving the extraction of the first premolar teeth.

MSH

naturally occurring nonessential aminoacid, chemical name 2-amino-3-hydroxypropionic acid; it may be synthesized from glycine or threonine and is involved in the biosynthesis of purines, pyrimidines, and other amino acids.
CSP

Amino acid with side chain -CH2OH.
NCI

A non-essential amino acid in humans (synthesized by the body), Serine is present and functionally important in many proteins. With an alcohol group, serine is needed for the metabolism of fats, fatty acids, and cell membranes; muscle growth; and a healthy immune system. It also plays a major role in pyrimidine, purine, creatine, and porphyrin biosynthetic pathways. Serine is also found at the active site of the serine protease enzyme class that includes trypsin and chymotrypsin. (NCI04)

serotonin

A biochemical messenger and regulator, synthesized from the essential amino acid L-TRYPTOPHAN. In humans it is found primarily in the central nervous system, gastrointestinal tract, and blood platelets. Serotonin mediates several important physiological functions including neurotransmission, gastrointestinal motility, hemostasis, and cardiovascular integrity. Multiple receptor families (RECEPTORS, SEROTONIN) explain the broad physiological actions and distribution of this biochemical mediator.
MSH

biochemical messenger and regulator, synthesized from tryptophan; in humans it is found primarily in the central nervous system, gastrointestinal tract, and blood platelets.
CSP

A hormone found in the brain, platelets, digestive tract, and pineal gland. It acts both as a neurotransmitter (a substance that nerves use to send messages to one another) and a vasoconstrictor (a substance that causes blood vessels to narrow). A lack of 5-hydroxytryptamine in the brain is thought to be a cause of depression.

serpiny

A family of serine proteinase inhibitors which are similar in amino acid sequence and mechanism of inhibition, but differ in their specificity toward proteolytic enzymes. This family includes alpha 1-antitrypsin, angiotensinogen, ovalbumin, antiplasmin, alpha 1-antichymotrypsin, thyroxine-binding protein, complement 1 inactivators, antithrombin III, heparin cofactor II, plasminogen inactivators, gene Y protein, placental plasminogen activator inhibitor, and barley Z protein. Some members of the serpin family may be substrates rather than inhibitors of SERINE ENDOPEPTIDASES, and some serpins occur in plants where their function is not known.
MSH

Irreversible serine proteinase inhibitors that exert their action on peptidases. Serpins can be localized inside, or outside of the cell, and are found in all groups of organisms with the exception of fungi. In human plasma, serpins represent approximately 2% of the total protein present.

nádor ze Sertoliho buněk

It may be associated with Peutz-Jeghers syndrome. In males, the presenting symptom is a slow growing testicular mass. Most cases follow a benign clinical course. In females it may present with estrogenic or androgenic manifestations. The vast majority of cases have a benign clinical course.
