Abstract
INTRODUCTION Nowadays, using electromagnetic devices (EMD) has been increased. However, the control of EMD hazards was poorly evaluated, especially those affected the hippocampus. Regular physical exercises are safe, easily, inexpensive, and acceptable for long-term use. It is reported that exercise protects against many health problems. AIM is to investigate the hypothesis of the possible prophylactic effect of exercise on the hippocampal damage induced by electromagnetic waves of Wi-Fi. MATERIAL AND METHODS Adult male albino rats were divided into four groups: group I (control), group II (exercise), group III (Wi-Fi), and group IV (exercise -Wi-Fi). Hippocampi were subjected to biochemical, histological, and immunohistochemical techniques. RESULTS In group III, a significant increase in the oxidative enzymes as well as decrease in antioxidant enzymes were detected in rat hippocampus. Additionally, the hippocampus showed degenerated pyramidal and granular neurons. An evident decrease in both PCNA and ZO-1 immunoreactivity was also noticed. In group IV, physical exercise alleviates the effect of Wi-Fi on previously mentioned parameters. CONCLUSION Regular physical exercise performance significantly minimizes the hippocampal damage and protects against the hazarders of chronic Wi-Fi radiation exposure.

Abstract
OBJECTIVES Growing evidence suggests that diabetes can cause multifactorial damage to the central nervous system (CNS) and may lead to dementia. However, the underlying mechanism of diabetes-induced central neuropathy remains sparse. In recent years, proteomics has provided better methods and means in analyzing the molecular mechanisms of disease. We applied proteomics to investigate the changes of hippocampal proteins in diabetic rats, with a view to discover the biomarkers of diabetes-induced central neuropathy and elucidated the potential biological relationships. METHODS Male Wistar rats were randomly divided into the control group and model group. The model group rats were injected intraperitoneally with streptozotocin. Morris water maze test was performed to evaluate the learning and memory of rats, and the hippocampus was taken out. Proteomics were adopted to investigate the changes of differentially expressed proteins. RESULTS Compared with the control group, the escape latency of the diabetic rats was significantly increased (P < 0.01, P < 0.05). It was presented that four differentially expressed proteins might be the potential biomarkers of diabetes-induced central neuropathy: septin 5, GRB2 related binding protein 2 (GAB2), casein kinase 1ε (CK1ε), aquaporin 4 (AQP4). These differentially expressed proteins were mainly involved in the following signaling pathways: apoptosis, glycine/serine/threonine metabolic and GTPase signaling pathway. CONCLUSIONS These findings provided reference insights into the underlying molecular pathogenesis of diabetes-induced CNS neuropathy.

Abstract
While acknowledging carotid atherosclerosis (CAS) as a risk factor for ischemic stroke, reports on its pathogenesis are scarce. This study aimed to explore the potential mechanism of CAS through RNA-seq data analysis. Carotid intima tissue samples from CAS patients and healthy subjects were subjected to RNA-seq analysis, which yielded, 1,427 differentially expressed genes (DEGs) related to CAS. Further, enrichment analysis (Gene Ontology, KEGG pathway, and MOCDE analysis) was performed on the DEGs. Hub genes identified via the protein-protein interaction network (PPI) were then analyzed using TRRUST, DisGeNET, PaGenBase, and CMAP databases. Results implicated inflammation and immunity in the pathogenesis of CAS. Also, lung disease was associated with CAS. Hub genes were expressed in multiple diseases, mainly regulated by RELA and NFKB1. Moreover, three small-molecule compounds were found via the CMAP database for management of CAS; hub genes served as potential targets. Collectively, inflammation and immunity are the potential pathological mechanisms of CAS. This study implicates CeForanide, Chenodeoxycholic acid, and 0317956-0000 as potential drug candidates for CAS treatment.
