sinkalid

An octapeptide hormone present in the intestine and brain. When secreted from the gastric mucosa, it stimulates the release of bile from the gallbladder and digestive enzymes from the pancreas.
MSH

A synthetic C-terminal octapeptide identical to the sequences of the endogenous cholecystokinin hormone. Mimic action of cholecystokinin, sincalide induces gallbladder smooth muscle contraction directly, thereby reducing gallbladder size, inducing bile evacuation, and secretion of pancreatic enzymes. In addition, this agent decreases esophageal sphincter tone and delays gastric emptying via cholinergic signaling.

sinusitida

Inflammation of the NASAL MUCOSA in one or more of the PARANASAL SINUSES.
MSH

inflammatory process of the mucous membranes of the paranasal sinuses that occurs in three stages: acute, subacute, and chronic; results from any condition causing ostial obstruction or from pathophysiologic changes in the mucociliary transport mechanism.
CSP

Sinusitis means your sinuses are infected or inflamed. Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen, this can block the sinuses and cause pain and infection.

Sinusitis can be acute, lasting for less than four weeks, or chronic, lasting much longer. Acute sinusitis often starts as a cold, which then turns into a bacterial infection. Allergies, pollutants, nasal problems and certain diseases can also cause sinusitis.

Symptoms of sinusitis can include fever, weakness, fatigue, cough and congestion. There may also be mucus drainage in the back of the throat, called postnasal drip. Treatments include antibiotics, decongestants and pain relievers. Using heat pads on the inflamed area, saline nasal sprays and vaporizers can also help.

geny v-sis

Human Oncogene SIS is a mutated variant of PDGFB Gene (PDGF/VEGF Family), which encodes 2 alternative isoforms of 241-aa 27-kDa (precursor) Platelet-Derived Growth Factor-Beta Chain, a potent mitogenic factor for mesenchymal cells characterized by a motif of eight cysteines and released by platelets upon wounding to stimulate adjacent cell growth; PDGF activates a RAS/PIK3/AKT1/IKK/NFKB1 pathway. PDGFB can exist as a disulfide-linked homodimer or heterodimer with Platelet-Derived Growth Factor Alpha. AA, BB, and AB, dimers bind to PDGF receptor and elicit a variety of cellular responses. A and B homodimers are implicated in transformation. PDGFB mutations are associated with meningioma. Reciprocal t(17;22)(q22;q13) translocations with COL1A1 result in unregulated growth factor expression and are associated with DFSP. Oncogene SIS disrupts normal cell function.

sesterské chromatidy – výměna

An exchange of segments between the sister chromatids of a chromosome, either between the sister chromatids of a meiotic tetrad or between the sister chromatids of a duplicated somatic chromosome. Its frequency is increased by ultraviolet and ionizing radiation and other mutagenic agents and is particularly high in BLOOM SYNDROME.
MSH

Any homology-dependent DNA strand exchange that occurs between sister chromatids in mitotic cells. This process is involved in creating combinations of genes that may be unique from the parent duplexes. Disruptions in this process may result in inviability, premature aging and predisposition to a broad variety of cancers.

situs inversus

A congenital abnormality in which organs in the THORAX and the ABDOMEN are opposite to their normal positions (situs solitus) due to lateral transposition. Normally the STOMACH and SPLEEN are on the left, LIVER on the right, the three-lobed right lung is on the right, and the two-lobed left lung on the left. Situs inversus has a familial pattern and has been associated with a number of genes related to microtubule-associated proteins.
