They were first synthesized by Alexander Shulgin and written up in his book PiHKAL (Phenethylamines i Have Known And Loved).SurE, survival protein E: In molecular biology, the protein domain surE refers to survival protein E. It was originally found that cells that did not contain this protein, could not survive in the stationary phase, at above normal temperatures, and in high-salt media.Crosstalk (biology): Biological crosstalk refers to instances in which one or more components of one signal transduction pathway affects another. This can be achieved through a number of ways with the most common form being crosstalk between proteins of signalling cascades.AAA proteins: For other uses see AAA (disambiguation)Smoke DZA: New York, New York, United StatesEnergy charge: Energy charge is an index used to measure the energy status of biological cells. It is related to ATP, ADP and AMP concentrations.DipyridamoleTheobromineSulfonucleotide reductase: In biology, a sulfonucleotide reductase is actually a class of enzymes involved in reductive sulfur assimilation. This reaction consists of a conversion from activated sulfate to sulfite.PurineTriazine: A triazine is class of nitrogen-containing heterocycles. The parent molecules' molecular formula is 333.TRNA (adenine57-N1/adenine58-N1)-methyltransferase: TRNA (adenine57-N1/adenine58-N1)-methyltransferase (, TrmI, PabTrmI, AqTrmI, MtTrmI) is an enzyme with system name S-adenosyl-L-methionine:tRNA (adenine57/adenine58-N1)-methyltransferase. This enzyme catalyses the following chemical reactionDeoxyadenosineBurst kinetics: Burst kinetics is a form of enzyme kinetics that refers to an initial high velocity of enzymatic turnover when adding enzyme to substrate. This initial period of high velocity product formation is referred to as the "Burst Phase".AminophyllineConcentration effect: In the study of inhaled anesthetics, the concentration effect is the increase in the rate that the Fa(alveolar concentration)/Fi(inspired concentration) ratio rises as the alveolar concentration of that gas is increased. In simple terms, the higher the concentration of gas administered, the faster the alveolar concentration of that gas approaches the inspired concentration.Concentrative nucleoside transporter: Human concentrative nucleoside transporters include SLC28A1, SLC28A2 and SLC28A3 proteins. SLC28A2 is a purine-specific Na+-nucleoside cotransporter localised to the bile canalicular membrane.BenzotriazoleNucleoside analogue: Nucleoside analogues are nucleosides which contain a nucleic acid analogue and a sugar. Nucleotide analogs are nucleotides which contain a nucleic acid analogue, a sugar and one to three phosphate groups.Apyrase: Apyrase (, ATP-diphosphatase, adenosine diphosphatase, ADPase, ATP diphosphohydrolase) is a calcium-activated plasma membrane-bound enzyme (magnesium can also activate it) () that catalyses the hydrolysis of ATP to yield AMP and inorganic phosphate. Two isoenzymes are found in commercial preparations from S.Coronary perfusion pressure: Coronary perfusion pressure (CPP) refers to the pressure gradient that drives coronary blood pressure, meaning the difference between the diastolic aortic pressure and the right atrial diastolic pressure. It is a term used mainly in research concerning cardiac arrest.Cyclase-associated protein family: In molecular biology, the cyclase-associated protein family (CAP) is a family of highly conserved actin-binding proteins present in a wide range of organisms including yeast, flies, plants, and mammals. CAPs are multifunctional proteins that contain several structural domains.BucladesineA. N. Hartley: Annie Norah Hartley (1902 – 1994), usually known simply as Norah Hartley, was a dog breeder and the first female board member of the Kennel Club.MizoribineS-adenosyl-L-homocysteine hydrolaseCalcium signaling: Calcium ions are important for cellular signalling, as once they enter the cytosol of the cytoplasm they exert allosteric regulatory effects on many enzymes and proteins. Calcium can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.Myocytolysis: Myocytolysis refers to a degenerative change (often reversible) that occurs to myocytes upon myocardial strain. This phenomenon tends to occur when neighboring cardiac muscle loses its ability to contract (i.NTP binding site: An NTP binding site is a type of binding site found in nucleoside monophosphate (NMP) kinases, N can be adenosine or guanosine. A P-loop is one of the structural motifs common for nucleoside triphosphate (NTP) binding sites, it interacts with the bound nucleotide's phosphoryl groups.Kennel clubColforsinMagnesium acetateCaffeineHyperaemiaVasodilation: Vasodilation (or vasodilatation) refers to the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins, large arteries, and smaller arterioles.New Zealand rabbitNorbormideTemporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingRetrograde perfusion: Retrograde perfusion is an artificial method of providing blood supply to an organ by delivering oxygenated blood through the veins. It may be performed during surgery that interrupts the normal arterial supply of blood to that organ.LodenosineAp4A: Diadenosine tetraphosphate or Ap4A is a putative alarmone, ubiquitous in nature being common to everything from bacteria to humans. Adenosine polyphosphates are capable of inducing multiple physiological effects.Phosphodiesterase inhibitor: A phosphodiesterase inhibitor is a drug that blocks one or more of the five subtypes of the enzyme phosphodiesterase (PDE), thereby preventing the inactivation of the intracellular second messengers cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) by the respective PDE subtype(s).Equilibrative nucleoside transporter: The equilibrative nucleoside transporter (ENT) family, also known as SLC29, is a group of plasmalemmal transport proteins which transport nucleoside substrates like adenosine into cells. There are four known ENTs, designated ENT1, ENT2, ENT3, and ENT4.OrganocatalysisArchaeosine synthase: Archaeosine synthase (, ArcS, TgtA2, MJ1022 (gene), glutamine:preQ0-tRNA amidinotransferase) is an enzyme with system name L-glutamine:7-cyano-7-carbaguanine aminotransferase. This enzyme catalyses the following chemical reactionAchy Breaky HeartPhosphotransferase: Phosphotransferases are a category of enzymes (EC number 2.7) that catalyze phosphorylation reactions.
