Maat
Definition:
(a.) Dejected; sorrowful; downcast.
Example Sentences:
(1) Neurons from rat fetal cerebral hemispheres were grown in a synthetic medium (Maat medium), as previously described, for different periods of time.
(2) Formation of the external aldimine with 2-methylaspartate is accompanied by tilting of the coenzyme ring by 44 degrees in cAAT and 39 degrees in mAAT.
(3) Distributions of the activities of the cytosolic (cAAT) and mitochondrial (mAAT) isoenzymes of aspartate aminotransferase were determined in rat retinal layers.
(4) The distribution of total AAT activity (tAAT = cAAT + mAAT) and of mAAT activity correlated well (r = 0.88-0.91) with the distribution of MDH activity.
(5) These results suggest that testosterone stimulated mAAT activity by induction of pmAAT mRNA.
(6) Phentolamine did not alter the noradrenaline effect on either mAAT or cAAT; it decreased significantly the free form of the mAAT activity only.
