Soil salinization is a common environmental problem that seriously affects the yield and quality of crops. Sugar beet (Beta vulgaris L.), one main sugar crops in world, shows strong tolerance to salt stress. To decipher molecular mechanism under stress, we conducted transcriptomic analyses two contrasting genotypes. best our knowledge, this first comparison salt-response transcriptomes with Compared salt-sensitive cultivar (S710), salt-tolerant (T710MU) showed better growth exhibited higher...

ABSTRACT Macrophages play critical roles in wound healing process. They switch from “classically activated” (M1) phenotype the early inflammatory phase to “alternatively (M2) later phase. However, dynamic process of macrophage switching diabetic wounds burdened with bacteria is unclear. In this report, Pseudomonas aeruginosa , frequently detected foot ulcers, was inoculated into cutaneous db/db mice mimic bacterium‐infected healing. We observed that P. infection impaired and quickly promoted...

Depression increases the risk of progression from mild cognitive impairment (MCI) to dementia, where impaired emotion regulation is a core symptom depression. However, neural mechanisms underlying decreased in individuals with MCI combined depressive symptoms are not precise. We assessed behavioral performance by tasks and recorded event-related electroencephalography (EEG) signals related simultaneously. EEG analysis, including potential (ERP), spectral perturbation (ERSP), functional...

Visual working memory (VWM), the core process inherent to many advanced cognitive processes, deteriorates with age. Elderly individuals usually experience defects in processing of VWM. The dorsolateral prefrontal cortex is a key structure for top-down control processes. Many studies have shown that repeated transcranial magnetic stimulation (rTMS) improves VWM by modulating excitability neurons target cortical region, though underlying neural mechanism has not been clarified. Therefore, this...
