Sea-Blue Histiocyte Syndrome
|
D012618 |
[A congenital disease caused by an inborn error involving APOLIPOPROTEINS E leading to abnormal LIPID METABOLISM and the accumulation of GLYCOSPHINGOLIPIDS, particularly SPHINGOMYELINS in the HISTIOCYTES. This disorder is characterized by SPLENOMEGALY and the sea-blue histiocytes in the spleen and bone marrow after May Grunwald staining.

Seals, Earless
|
D046048 |
[The best known species of earless seals, inhabiting the North Atlantic and Arctic Oceans. Harp seals get their name from a horse-shaped band of black fur on the back of the male adults. They were previously considered part of the genus Phoca.

Seasonal Affective Disorder
|
D016574 |
[A syndrome characterized by depressions that recur annually at the same time each year, usually during the winter months. Other symptoms include anxiety, irritability, decreased energy, increased appetite (carbohydrate cravings), increased duration of sleep, and weight gain. SAD (seasonal affective disorder) can be treated by daily exposure to bright artificial lights (PHOTOTHERAPY), during the season of recurrence.

Seaweed
|
D012624 |
[Multicellular marine macroalgae including some members of red (RHODOPHYTA), green (CHLOROPHYTA), and brown (PHAEOPHYTA) algae. They are widely distributed in the ocean, occurring from the tide level to considerable depths, free-floating (planktonic) or anchored to the substratum (benthic). They lack a specialized vascular system but take up fluids, nutrients, and gases directly from the water. They contain CHLOROPHYLL and are photosynthetic, but some also contain other light-absorbing pigments. Many are of economic importance as FOOD, fertilizer, AGAR, potash, or source of IODINE.

Sebaceous Glands
|
D012627 |
[Small, sacculated organs found within the DERMIS. Each gland has a single duct that emerges from a cluster of oval alveoli. Each alveolus consists of a transparent BASEMENT MEMBRANE enclosing epithelial cells. The ducts from most sebaceous glands open into a HAIR FOLLICLE, but some open on the general surface of the SKIN. Sebaceous glands secrete SEBUM.

SecA Proteins
|
D000081416 |
[ATPases that provide energy for the translocation of proteins across bacterial PLASMA MEMBRANES and THYLAKOID membranes, by the SEC TRANSLOCATION CHANNELS. SecA is a component of the bacterial preprotein translocase which is comprised of SecA, the SECYEG TRANSLOCON, and the accessory domain proteins SecD, SecF, YajC, and YidC.

Secologanin Tryptamine Alkaloids
|
D046948 |
[An alkaloidal extract from RAUWOLFIA.
, Compounds formed by condensation of secologanin with tryptamine resulting in a tetrahydro-beta-carboline which is processed further to a number of bioactive compounds. These are especially found in plants of the APOCYNACEAE; LOGANIACEAE; and RUBIACEAE families.
, Alkaloids from Rauwolfia serpentina Benth and other species. The prototype is RESERPINE, which is a depleter of catecholamines and serotonin from the sympathetic postganglionic fibers and brain areas. They have been used in hypertension and psychoses despite their wide range of potentially adverse effects.

Second Harmonic Generation Microscopy
|
D000073798 |
[A microscopic imaging technique that takes advantage of the process of harmonic generation that occurs when photons interact to generate new photons of a different wavelength. In second harmonic generation, two photons of the same wavelength and frequency, such as from a LASER, interact inside a medium and are converted to a photon of twice the frequency and half of the wavelength of the two incident photons. The light signals captured are used to produce images that are dependent on the unique optical properties of the material.

Second Messenger Systems
|
D015290 |
[Systems in which an intracellular signal is generated in response to an intercellular primary messenger such as a hormone or neurotransmitter. They are intermediate signals in cellular processes such as metabolism, secretion, contraction, phototransduction, and cell growth. Examples of second messenger systems are the adenyl cyclase-cyclic AMP system, the phosphatidylinositol diphosphate-inositol triphosphate system, and the cyclic GMP system.
