In the present study, we examined the effect of etanercept on high mobility group box 1 (HMGB1) expression in dorsal root ganglion (DRG) neuron cells in a rat model of chronic constriction injury (CCI) of the sciatic nerve, with the aim of exploring the molecular mechanism underlying the therapeutic effect of etanercept on sciatica-related nociception and the potential interaction between tumor...

Mild traumatic brain injury (mTBI) is increasingly recognized as a significant public health problem which warrants additional research. Part of the effort to understand mTBI and concussion includes modeling in animals. Controlled cortical impact (CCI) is a commonly employed and well-characterized model of experimental TBI that has been utilized for three decades. Today, several commercially av...

BACKGROUND Most studies investigate the association between the baseline Romano-Charlson comorbidity index (CCI) and survival on hemodialysis (HD). Few consider the effect of progression in the CCI score (CCIp) on patient survival before HD initiation. That is CCIp = CCI-1 - CCI-3, where CCI(-1) is the CCI score in the first year before HD initiation, and CCI-3 is the CCI score in the third yea...

background: p2x4 receptor (p2x4r), a purinoceptor expressed in activated spinal microglia, plays a key role in the pathogenesis of neuropathic pain. spinal nerve injury induces up-regulation of p2x4r on activated microglia in the spinal cord, and blockade of this receptor can reduce neuropathic pain. the present study was undertaken to determine whether paroxetine, an inhibitor of p2x4r, could ...

To determine if the mammalian target of rapamycin (mTOR) inhibitor CCI-779 can sensitize head and neck squamous cell carcinoma (HNSCC) to radiotherapy (XRT) and compare the radiosensitizing effects to cisplatin with its known considerable toxicity. Radiosensitizing effects of CCI-779 were assayed on HNSCC cell lines in vitro. CCI-779 (5 mg/kg), cisplatin (1 mg/kg), and XRT (2 Gy) alone and in c...

The Chronic Constriction Injury of the Infraorbital Nerve (CCI-ION) is a well-established model to study facial sensory changes related to trigeminal neuropathic pain. CCI-ION induces heat hypersensitivity that resolves within 2-3 weeks and a delayed mechanical hypersensitivity that emerges during the second week post-injury. The role of descending facilitatory pain pathways from the rostro ven...

Internal jugular vein (IJV) compression has been shown to reduce axonal injury in pre-clinical traumatic brain injury (TBI) models and clinical concussion studies. However, this novel approach to prophylactically mitigating TBI through venous congestion raises concerns of increasing the propensity for hemorrhage and hemorrhagic propagation. This study aims to test the safety of IJV compression ...

Prevention and treatment of neuropathic pain (NP) is one of the most difficult problemsin clinical practice since the underlying mechanism of NP is unclear. In previous studies, theincreased production of nitric oxide (NO) has been closely linked to the induced NP. In thisstudy, we assessed the effect of atorvastatin through NO mechanism, on inflammation, thermalhyperalg...

OBJECTIVE Health-care expenditures are strongly influenced by overall illness burden. Appropriate risk adjustment is required for correct policy analysis. We compared three risk adjustment methods: the Charlson comorbidity index (CCI), the chronic disease score (CDS), and the Agency for Healthcare Research and Quality's comorbidity index (AHRQCI) in terms of their estimation power in analyzing ...
