Comparative lipidomics of mouse brain exposed to enriched environment.
Several studies have shown that housing conditions and environmental exposure to a series of stimuli lead to behavior improvement in several species. While more works have been focused on illustrating changes of the proteome and transcriptome following enriched environment exposure in mice, little has been done to understand changes in the brain metabolome in this paradigm due to the complexity...
متن کاملThe ratio of striatal D1 to muscarinic receptors changes in aging rats housed in an enriched environment.
The enriched environment (EC) causes morphological plasticity in striatal cells that express D1 and D2 receptors. We used radioligand binding assays to examine whether EC produces plasticity in striatal receptor density and receptor density ratios. After 30 days of EC, 2-year-old rats had a higher ratio of D1 to muscarinic receptors in striatum relative to singly housed rats. Assays also showed...
متن کاملChanges of Cortisol and Glucose Concentrations in Rats Exposed to MR Imaging Field
Background: MR imaging is one of the best diagnostic modalities in medicine. During an MR imaging examination, three types of field are employed to produce images. Various experimental studies have been performed about the effects of each single type of field but only few studies are available on their combination to generate MR imaging. The main objective of this research work is to study the ...
متن کاملpush-out bond strength of calcium enriched mixture exposed to alkaline environment
statement of problem: calcium hydroxide which is commonly used as an intracanal medicament, changes the ph of dentin and periradicular tissues to an alkaline ph. in some clinical situations, endodontic reparative cements like calcium enriched mixture cement are used after calcium hydroxide therapy. however, the alkaline ph may affect the physical properties of this cement. objectives: this stud...
متن کاملShort exposure to an enriched environment accelerates plasticity in the barrel cortex of adult rats
Cortical sensory neurons adapt their response properties to use and disuse of peripheral receptors in their receptive field. Changes in synaptic strength can be generated in cortex by simply altering the balance of input activity, so that a persistent bias in activity levels modifies cortical receptive field properties. Such activity-dependent plasticity in cortical cell responses occurs in rat...
