Cryoprotectant: A cryoprotectant is a substance used to protect biological tissue from freezing damage (i.e.Ethylene glycol poisoningOvarian tissue cryopreservation: Ovarian tissue cryopreservation is cryopreservation of tissue of the ovary of a female.Liquid nitrogen vehicle: A liquid nitrogen vehicle is powered by liquid nitrogen, which is stored in a tank. Traditional nitrogen engine designs work by heating the liquid nitrogen in a heat exchanger, extracting heat from the ambient air and using the resulting pressurized gas to operate a piston or rotary motor.Propylene oxideDimethyl sulfoxideGlycerol 3-phosphate: -glycerol 1-phosphate-glycerol 3-phosphate-α-glycerophosphate-α-phosphoglycerolHyperactivation: Hyperactivation is a type of sperm motility. Hyperactivated sperm motility is characterised by a high amplitude, asymmetrical beating pattern of the sperm tail (flagellum).Spermiogenesis: Spermiogenesis is the final stage of spermatogenesis, which sees the maturation of spermatids into mature, motile spermatozoa. The spermatid is more or less circular cell containing a nucleus, Golgi apparatus, centriole and mitochondria.List of Antarctic ice streams: This is a list of Antarctic ice streams.Permissive temperature: The permissive temperature is the temperature at which a temperature sensitive mutant gene product takes on a normal, functional phenotype.http://www.Chaenocephalus aceratus: Chaenocephalus aceratus, the blackfin icefish, is a species of crocodile icefish known from around Bouvet Island and the northern Antarctic Peninsula where it occurs at depths of . This species grows to a length of TL.Polypedilum vanderplanki: Polypedilum vanderplanki or the sleeping chironomid, is a dipteran in the family Chironomidae. It occurs in the semi-arid regions of the African continent (e.DimethylformamidePolyvinylpyrrolidoneChronic cellular dehydrationAlpha,alpha-trehalose synthase: Alpha,alpha-trehalose synthase (, trehalose synthase, trehalose synthetase, UDP-glucose:glucose 1-glucosyltransferase, TreT, PhGT) is an enzyme with system name ADP-glucose:D-glucose 1-alpha-D-glucosyltransferase. This enzyme catalyses the following chemical reactionLactate dehydrogenase elevating virus: Lactate dehydrogenase elevating virus, or LDV for short, belongs to part of the arteriviridae family and the nidovirales order. Also included in the nidovirales order are the coronaviridae.Acclimatization: Acclimatization (UK also acclimatisation; US also acclimation) is the process in which an individual organism adjusts to a gradual change in its environment (such as a change in temperature, humidity, photoperiod, or pH), allowing it to maintain performance across a range of environmental conditions. Acclimation occurs in a short period of time (days to weeks), and within the organism's lifetime (compare to adaptation).Sucrose gap: The sucrose gap technique is used to create a conduction block in nerve or muscle fibers. A high concentration of sucrose is applied to the extracellular space to increase resistance between two groups of cells, which prevents the correct opening and closing of sodium and potassium channels.Cold shock response: Cold shock response is the physiological response of organisms to sudden cold, especially cold water.Outline of water: The following outline is provided as an overview of and topical guide to water:
