Abstract Brain endothelial cell (bEC) dysfunction is the main factor of blood-brain barrier (BBB) breakdown, which triggers a vicious cycle aggravating traumatic brain injury (TBI) pathogenesis. Previous studies have revealed that neutrophil extracellular traps (NETs) released by neutrophils can lead to BBB disruption, but there lack research on underlying mechanisms after TBI. Here, excessive NETs were found in both contused tissue and circulation following We could activate TLR4/NF-κB...

Nausea, an unpleasant symptom of diabetic gastroparesis (DMGP), has been reported to be alleviated by needleless transcutaneous electrical acupuncture (TEA). Our study was designed utilize electroencephalography (EEG) and electrogastrography (EGG) recordings investigate the central peripheral responses TEA in treatment nausea DMGP patients.Eleven subjects underwent simultaneous EEG EGG testing while grading severity following 30-minute intervals of: (1) baseline, (2) visual stimulation (VS)...

Phosphatase and tensin homolog deleted on chromosome ten (PTEN) is a dual lipid protein phosphatase. Multiple mechanisms contributing to the regulation of PTEN levels have been identified thus far, including post-translational modifications, epigenetic mechanisms, transcriptional mechanisms. In present study, we ubiquitin-specific peptidase 22 (USP22) as novel deubiquitination-modifying enzyme PTEN. Furthermore, by inducing deubiquitination inhibiting degradation PTEN, USP22 could induce...

Abstract Background Gastric electrical stimulation ( GES ) has been suggested as a potential treatment for patients with gastric motility disorders. The aim of this study was to examine the effects and mechanisms on visceral pain in awaken rats. Methods Under anesthesia, acetic acid injected into submucosal layer stomach wall S prague– D awley SD male Each rat chronically placed an intragastric balloon two pairs electrodes serosa at neck muscles electromyography EMG recordings respectively....

Gastric electrical stimulation (GES) has been used to treat obesity with unclear mechanisms and limited parameter ranges. This study explores effects of GES parameters on ventral medial hypothalamic (VMH) activity, feeding, body weight in diet-induced obese (DIO) rats. For experiment 1, discharge rates were recorded 39 gastric distension-responsive (GD-R) neurons 12 DIO Basal compared under using varied pulse amplitudes, widths, frequencies, train-on times. 2, a crossover 16 rats measured...

The incidence of gastrointestinal stromal tumors (GISTs) located in the colon is rare. Current studies mainly focus on case reports for colonic GISTs. Therefore, a population-based analysis was useful to guide clinical treatment strategy. patients were selected from 2000 2015 based Surveillance, Epidemiology, and End Results (SEER) database. Patients' demographics, tumor characteristics, incidence, treatment, survival retrieved analysis. 249 cases GISTs collected. male-female ratio close 1 :...
