CA1


Also found in: Acronyms.

CA1

A gene on chromosome 8q21.2 that encodes a carbonic anhydrase, a zinc metalloenzyme that catalyses the reversible hydration of carbon dioxide. Carbonic anhydrases participate various biological processes, including respiration, calcification, maintaining acid-base balance, bone resorption and producing aqueous humour, cerebrospinal fluid, saliva and gastric acid. CA1 is a cytosolic protein highly expressed in erythrocytes.

On assessing the hippocampal activity of the mice, the researchers found that rodents that had sufficient sleep after the learning task demonstrated stronger sleep-related oscillations in the CA1 region of the hippocampus, compared with sleep-deprived mice.
For quantitative analyses of NeuN-immunoreactive (NeuN[sup]+) and F-J B-positive (F-J B[sup]+) cells, we counted cells in a 250 [micro]m x 250 [micro]m including the stratum pyramidale at the center of the CA1 using an image analyzing system (software: Optimas 6.
The stratum oriens was not included in the counts to be the outermost layer of the CA1 hippocampus, where the reactions end up in shrunken anamorphic tissue (edge effect) with very intense background.
After the LFPs in the MDT and CA1 were collected, notch filtering was performed to filter out the 50 Hz power noise.
activity was statistically significant between groups in the CA1 area of the ventral hippocampus and CA3 area, showing higher C.
La fertilizacion con CA1 + 1% estimulo, tanto en rizosfera como en suelo a distancia, mayor densidad de Azospirillum (11 x [10.
Possibly the astrocytic hyper-responsiveness observed in this study corresponds to a reactive gliosis given the course of ischemia (13 days) being in agreement with other studies in which, after seven days of I/R, reactive gliosis was evident in hippocampal CA1 (20) and most strikingly in the peri-infarction areas (22).
At the end of experimental study, the brains of mice were removed, and normal and degenerative pyramidal neurons were counted in the hippocampal CA1, CA2, CA3 regions by light microscopy.
Quantitative analysis of morphological changes was carried out by counting the number of both viable and damaged neurons in the CA1 region of the hippocampus.
In analysis of the subfields; in males, while CA1 subfield showed the right dominancy, CA2/3, CA4 and the subiculum had more neuron number in the left hemisphere than the right.

Supporting the behavioral findings, stereological assessment of CA1 pyramidal neurons documented greater neuronal loss in KA-treated controls compared to KA-treated rats on the BB diet.
