Abstract

Good sleep is necessary for optimal health, especially for mental health. Insomnia, sleep deprivation will make your ability to learn and memory impaired. Nevertheless, the underlying pathophysiological mechanism of sleep disorders-induced cognitive decline is still largely unknown. In this study, the sleep deprivation of animal model was induced by chronical sleep interruption (CSI), the behavioral tests, biochemical index determinations, and a liquid chromatography-mass spectrometry (LC-MS) based serum metabolic profiling analysis were performed to explore the effects of CSI on cognitive function and the underlying mechanisms. After 14-days CSI, the cognitive function of the mice was evaluated by new objects preference (NOP) task and temporal order judgment (TOJ) task. Serum corticosterone (CORT), and brain Malondialdehyde (MDA), Superoxide Dismutase (SOD), and Catalase (CAT) levels were determined by ELISA kits. Data were analyzed by Principal Component Analysis (PCA), Partial Least Squares project to latent structures-Discriminant Analysis (PLS-DA), and Student's t-test. We found that the cognitive function of the mice was significantly affected by CSI. Besides, levels of CORT and MDA were higher, and SOD and CAT were lower...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
