Intranasal oxytocin alleviates postsurgical pain and comorbid anxiety in mice: Participation of BK(Ca) channels in the hippocampus.

The affective dimension in postsurgical pain is still poorly understood. Since neuropeptide oxytocin (OXT) has been implicated in a broad spectrum of pain and negative emotion, we investigated the potential therapeutic effect of intranasal OXT on postsurgical pain and associated anxiety in a mice model of plantar incision. The role of large conductance Ca(2+)-activated K(+) (BK(Ca)) channels was explored by using behavioral pharmacology experiments.

Single-Layer GaInSe: Promising Water-Splitting Photocatalyst with Solar Conversion Efficiency over 30% from Theoretical Calculations.

Hydrogen energy from solar water-splitting is known as an ideal method with which to address the energy crisis and global environmental pollution. Herein, the first-principles calculations are carried out to study the photocatalytic water-splitting performance of single-layer GaInSe under biaxial strains from -2% to +2%. Calculations reveal that single-layer GaInSe under various biaxial strains has electronic bandgaps ranging from 1.

Stellate ganglion block ameliorated central post-stroke pain with comorbid anxiety and depression through inhibiting HIF-1α/NLRP3 signaling following thalamic hemorrhagic stroke.

Background: Central post-stroke pain (CPSP) is an intractable and disabling central neuropathic pain that severely affects patients' lives, well-being, and socialization abilities. However, CPSP has been poorly studied mechanistically and its treatment remains challenging. Here, we used a rat model of CPSP induced by thalamic hemorrhage to investigate its underlying mechanisms and the effect of stellate ganglion block (SGB) on CPSP and emotional comorbidities.

Ropivacaine-induced seizures evoked pain sensitization in rats: Participation of 5-HT/5-HT3R.

Due to the increasing use of local anesthetic techniques in various healthcare settings, local anesthetic toxicity still occurs. Seizures are the most common symptom of local anesthetic toxicity. The relationship between local anesthetic-induced seizures and the sensation of pain has not been established till now.

Positive Emotions and Entrepreneurial Intention: The Mediating Role of Entrepreneurial Cognition.

Under the background of "mass entrepreneurship and innovation," entrepreneurship and innovation for college students not only alleviates the current social employment pressure but also sets off the upsurge of their entrepreneurship. It is a significant field to research the entrepreneurial intention of undergraduates as potential entrepreneurs, which covers the study of entrepreneurial intention from the perspective of personal traits and entrepreneurial cognition. This article studies entrepreneurial intention from two aspects: irrational positive emotions and rational entrepreneurial cognition, which aims to reveal the mechanism of positive emotions and entrepreneurial cognition on entrepreneurial intention.

Intervertebral foramen injection of plerixafor attenuates neuropathic pain after chronic compression of the dorsal root ganglion: Possible involvement of the down-regulation of Nav1.8 and Nav1.9.

Neuropathic pain is a common chronic pain condition with major impact on quality of life. However, its physiopathologic mechanism remains unknown and pain management is still a challenge. Accumulating evidence indicated that C-X-C chemokine receptor type 4 (CXCR4) played a critical role in the process of pain.

The analgesic effects of ulinastatin either as a single agent or in combination with sufentanil: A novel therapeutic potential for postoperative pain.

Ulinastatin is a broad-spectrum protease inhibitor widely used for the treatment of various inflammation-related diseases owing to its recognized excellent anti-inflammatory and cytoprotective properties. However, whether ulinastatin can relieve postoperative pain remains unclear. In this study, we evaluated the analgesic effects of ulinastatin administered either as a single agent or in combination with sufentanil in a validated preclinical rat model of postoperative pain induced by plantar incision.

Involvement of the p38 MAPK-pHsp27 pathway in vascular hyporeactivity induced by obstructive jaundice in rats.

Patients with obstructive jaundice are prone to develop cardiovascular complications during surgery. However, the underlying mechanisms remain largely unknown. The present study was aimed to investigate the role of p38 MAPK-pHsp27 pathway in vascular hyporesponsiveness induced by obstructive jaundice.

Neuromuscular effect of dexmedetomidine on sevoflurane: an open-label, dose-escalation clinical trial.

Background: Sevoflurane presents reliable central neuromuscular effects. However, little knowledge is available regarding the interaction between sevoflurane and demedetomidine. We evaluated the neuromuscular effect of dexmedetomidine on sevoflurane in patients with normal neuromuscular transmission and calculated the 50% effective concentration (EC50).

Comparison of Continuous Noninvasive Blood Pressure Monitoring by TL-300 With Standard Invasive Blood Pressure Measurement in Patients Undergoing Elective Neurosurgery.

Background: Intraoperative blood pressure (BP) is one of the basic vital signs monitoring. Compared with standard invasive BP measurement, TL-300 allows for a continuous and beat-to-beat noninvasive intraoperative BP monitoring. The current retrospective study compared the accuracy and precision of this noninvasive technique for continuous BP monitoring with that of standard invasive BP measurement in patients undergoing elective neurosurgery.

[Effects of high thoracic epidural anesthesia on ventricular remodeling and expression of beta(3)-adrenoceptor in rats with heart failure induced by acute myocardial infarction].

Objective: To investigate the effect of high thoracic epidural anesthesia on ventricular remodeling and cardiac function in rats with heart failure induced by myocardial infarction, and to investigate their mechanism.

Methods: Rats that had been established successively model were randomly divided into S group (n = 12), HTEA group and CHF group (24/group). 9.
