Background: It is frequently reported that neuropathic pain is associated with abnormalities in brain function and structure as well as cognitive deficits. However, the contributing mechanisms have remained elusive.

Objectives: We aimed to investigate the systemic ultrastructural changes of the peripheral nervous system (PNS) and central nervous system (CNS) in rats with trigeminal neuralgia (TN) induced by cobra venom, as well as the effects and mechanisms of electroacupuncture (EA) and pregabalin (PGB) on TN.

Purpose: It is unclear whether neuropathological structural changes in the peripheral nervous system and central nervous system can occur in the spared nerve injury model. In this study, we investigated the pathological changes in the nervous system in a model of neuropathic pain as well as the effects of electroacupuncture (EA) and pregabalin (PGB) administration as regards pain relief and tissue repair.

Patients And Methods: Forty adult male SD rats were equally and randomly divided into 4 groups: spared nerve injury group (SNI, n = 10), SNI with electroacupuncture group (EA, n = 10), SNI with pregabalin group (PGB, n =10) and sham-operated group (Sham, n=10).

While tremendous progress has recently been made in perovskite light-emitting diodes (PeLEDs), large-area blue devices feature inferior performance due to uneven morphologies and vast defects in the solution-processed perovskite films. To alleviate these issues, a facile and reliable interface engineering scheme is reported for manipulating the crystallization of perovskite films enabled by a multifunctional molecule 2-amino-1,3-propanediol (APDO)-triggered "anchoring effect" at the grain-growth interface. Sky-blue perovskite films with large-area uniformity and low trap states are obtained, showing the distinctly improved radiative recombination and hole-transport capability.

Background: Numerous therapies have been developed for the treatment of chronic pelvic pain (CPP). Oxygen-ozone therapy is a new method for the treatment of CPP.

Objectives: This article evaluated the feasibility of ultrasound-guided peritoneal perfusion with ozone in patients with CPP.

Background: Thalamic pain is a neuropathic pain syndrome that occurs as a result of thalamic damage. It is difficult to develop therapeutic interventions for thalamic pain because its mechanism is unclear. To better understand the pathophysiological basis of thalamic pain, we developed and characterized a new rat model of thalamic pain using a technique of microinjecting cobra venom into the ventral posterolateral nucleus (VPL) of the thalamus.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder without effective treatment. Accumulating evidence demonstrates the production and deposition of amyloid-β peptides (Aβ) in the pathological mechanism of this disease. In our study, we investigated the effect of an ozone intraperitoneal injection on AD pathology in APP/PS1 transgenic mouse model.

We report the successful treatment of idiopathic intractable hiccups with cisatracurium under intravenous general anesthesia. The patient had a history of hiccups for 19 years that were refractory to a variety of treatments. When his hiccups were accompanied by vomiting, insomnia, shortness of breath, and poor oral intake for 9 days, he sought relief.

Background: Ambient aerosol fine particulate matter (PM2.5) is associated with male reproductive toxicity in experiments and may have adverse effects in the female. However, studies evaluating the protective effects and precise mechanisms of aspirin, Vitamin C, Vitamin E, or ozone against toxic effects of PM2.

Background: Electroacupuncture (EA) is widely applied to treat neuropathic pain. Brachial plexus neuralgia (BPN) is a common form of chronic persistent pain. Few studies have evaluated the analgesic effects and mechanism of EA using the novel animal model of BPN.

Background: A new animal model of trigeminal neuralgia produced by injecting cobra venom into the infraorbital nerve (ION) trunk in rats had been developed. We tested and extended the model by observing the ultrastructural alterations of neurons and ameliorative effect of pregabalin in cobra venom-induced pain behaviors of rats.

Objectives: The goal of this study was to prove the feasibility of the cobra venom-induced model of trigeminal neuralgia and to demonstrate the demyelination change of ION and medulla oblongata is the major pathological change of trigeminal neuralgia.

Objectives: Electroconvulsive therapy (ECT) has dramatically reduced musculoskeletal complications when carried out with muscle relaxants under general anesthesia. However, seizure quality can be affected by the depth of anesthesia and choice of anesthetic agent. The purpose of this study was to describe a general anesthetic technique for ECT by using laryngeal mask, bispectral index (BIS), and muscle relaxant monitoring.

Background: Patients with chronic pain usually suffer from cognitive impairment, with memory deterioration being the most common deficit that affects daily functioning and quality of life. The causes for this impairment are not clear despite intensive clinical studies. Few studies have evaluated impaired learning using animal models of persistent pain.

Background: To establish a new animal model for the study of neuropathic pain developed by administration of cobra venom to the brachial plexus (BP) lower trunk.

Methods: Fifty-eight adult male Sprague-Dawley rats were randomly divided into 5 groups. Under pentobarbital sodium anesthesia, cobra venom was injected into the lower trunk or sham operation was performed in the animals.

4,4'-Bipyridine-2-meth-oxy-benzoic acid (1/2).

Acta Crystallogr Sect E Struct Rep Online

March 2012

The asymmetric unit of the title compound, C(10)H(8)N(2)·2C(8)H(8)O(3), contains two 2-meth-oxy-benzoic acid mol-ecules and one 4,4'-bipyridine mol-ecule. The 4,4'-bipyridine mol-ecule is disordered over two positions in a 1:1 ratio. In the crystal, the 2-meth-oxy-benzoic acid and 4,4'-bipyridine mol-ecules are connected by inter-molecular O-H⋯N hydrogen bonds.

Background: Understanding the mechanism of trigeminal neuralgia may be elucidated by developing laboratory animal models that closely mimic the features of this specific type of neuropathic pain. We have developed an experimental animal model for trigeminal neuralgia using a technique of injecting cobra venom into the infraorbital nerve (ION) trunk.

Methods: Male Sprague-Dawley rats were subjected to the administration of cobra venom or saline into the ION trunk.
