Glossary Term
Any of the 99 numbered points that divide an ordered set of scores into 100 parts each of which contains one-hundredth of the total.
Glossary Term
Quantity of dimension one used to express on a scale from 0 to 14 the amount-of-substance concentration of hydrogen ion of dilute aqueous solution, calculated as the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter.
Indicators
A long-acting barbituric acid derivative with antipsychotic property. Phenobarbital binds to and activates the gamma-aminobutyric acid (GABA)-A receptor, thereby mimicking the inhibitory actions of GABA in the brain. The activation effects of the phenobarbital-receptor-ionophore complex include increased frequency of chloride channel openings, membrane hyperpolarization and ultimately synaptic inhibition and decreased neuronal excitability. In addition, this agent inhibits glutamate induced depolarization.
Tests
The determination of the amount of phenobarbital present in a sample.
Glossary Term
The assemblage of traits or outward appearance of an individual. It is the product of interactions between genes and between genes and the environment.
Indicators
A hydantoin derivative and a non-sedative antiepileptic agent with anticonvulsant activity. Phenytoin potentially acts by promoting sodium efflux from neurons located in the motor cortex reducing post-tetanic potentiation at synapses. The reduction of potentiation prevents cortical seizure foci spreading to adjacent areas, stabilizing the threshold against hyperexcitability. In addition, this agent appears to reduce sensitivity of muscle spindles to stretch causing muscle relaxation.
Indicators
This gene plays a role in transcriptional regulation.
Tests
The determination of the amount of phospholipid scramblase 1 present in a sample.
Glossary Term
A score reported on a logarithmic scale representing the probability that a nucleotide base was incorrectly called by the base caller.
Indicators
This gene is involved in phosphoinositol signaling.
Tests
The determination of a sub-population of plasmablasts in a sample.
Tests
The determination of the amount of plasmacytoid dendritic cells present in a sample.
