n the future to translate our findings into clinical practice. Besides, to apply the results to the target osteoporotic population, new studies will be needed, including a specimen from an osteoporotic patient and the effect of osteoporosis on the constitutive model of bone.Neisseria meningitidis (N. meningitidis) is a human-specific pathogen and a major cause of meningitis and septicemia with a high case fatality rate. N. https://www.selleckchem.com/products/sar439859.html meningitidis may penetrate the nasopharyngeal mucosal membrane and cause severe meningitis, a mucosal immune response plays a key role in the defense against meningococcal infections. Our previous study demonstrated that N. meningitidis serogroup B 0315 (NMB0315) was a vaccine candidate against N. https://www.selleckchem.com/products/sar439859.html meningitidis serogroup B (NMB) through parenteral immunization. link2 In this study, immunopotentiators (C48/80 or CpG-ODN) were loaded into chitosan nanoparticle (Chi NP) to form combination adjuvants (Chi-CpG NP and Chi-C48/80 NP) and adopted to enhance the immunogenicity of NMB0315 through intranasal immunization. link2 link3 The experimental results have indicated that both Chi-CpG NP and Chi-C48/80 NP are effective mucosal adjuvants for the induction of significantly higher rNMB0315-specific IgG, IgG1, IgG2a and sIgA antibodies. Meanwhile, Chi-CpG NP and Chi-C48/80 NP could change the ratio of IgG1/IgG2a, inducing a more balanced cellular/humoral immune response. Chi-CpG NP and Chi-C48/80 NP also boosted interleukin-4 (IL-4), interferon-γ (IFN-γ) and interleukin-17 A (IL-17A) production by splenocytes. The bactericidal antibodies have been detected in sera from mice immunized with rNMB0315 + Chi-CpG NP and rNMB0315 + Chi-C48/80 NP. Overall, the combination adjuvants could be applicable to the development of a mucosal vaccine against NMB.

Considering the role of inflammation in the outcome of sepsis and the widespread use of imipenem in the disease, this study was designed to assess the effect of imipenem on the dynamics of inflammatory responses in the sepsis mouse model.

Cecal Ligation and Puncture (CLP) model was used to induce sepsis in mice. C57BL/6 mice were divided into sham, CLP-induced sepsis mice, CLP-induced sepsis mice receiving 25mg/kg, and 125mg/kg imipenem. Blood and liver samples were obtained and bacterial load, endotoxin level, and liver enzymes were evaluated. The concentration and mRNA expression of cytokines were also determined.

Sepsis mice treated with a high dose (125mg/kg) of imipenem showed a significant reduction in bacterial load, while increased liver enzymes, endotoxin level, and inflammatory cytokine production in plasma and liver. In contrast, significant reduction in the liver enzymes, bacterial load, endotoxin levels, and inflammatory cytokine levels was observed in the mice treated with a low dose (25mg/kg) of imipenem compared with other mice groups. https://www.selleckchem.com/products/sar439859.html Liver tissue pathology of mice indicated little tissue destruction in the sepsis mice treated with 25mg/kg of imipenem compared to other groups. Mice receiving 25mg/kg of imipenem had better survival rate.

Our results demonstrated the dose-dependent effect of subcutaneous administration of imipenem on the inflammatory responses in sepsis mice. A dose of 25mg/kg imipenem resulted in better pathology, lower inflammatory mediators, and increased survival rate in sepsis mice.

Airway epithelial cells (AECs) act as the first barrier protecting against invasion of environment agents and maintain integrity of lung structure and function. Dysfunction of airway epithelial barrier has been shown to be involved in ALI/ARDS pathogenesis. Yet, the exact mechanism is still obscure. Our study evaluated whether the receptor for advanced glycation end products (RAGE) mediates impaired airway epithelial barrier in LPS-induced murine ALI model.

Male BALB/c mice were subjected to intratracheal instillation of LPS to generate an ALI model. Inhibitors of RAGE, FPS-ZM1 and Azeliragon were respectively given to the mice through intraperitoneal injection. Bronchoalveolar lavage fluid (BALF) and lung tissues were collected for further analysis.

LPS exposure led to markedly increased expression of RAGE and its ligands HMGB1, HSP70, S100b. Treatment of FPS-ZM1 or Azeliragon not only effectively descended the expression of RAGE and its ligands but also attenuated LPS-induced neutrophil-predominant airway inflammation and injury, decreased levels of IL-6, IL-1β and TNF-α in BALF, alleviated increased alveolar-capillary permeability and pulmonary edema. LPS stimulation significantly impaired the integrity of airway epithelium, paralleled with dislocation of adheren junction (AJ) protein E-cadherin at cell-cell contacts and down-expression of both AJ and tight junction (TJ) proteins Claudin-2 and occludin, all of which were dramatically rescued by RAGE inhibition.

Chronic cerebral hypoperfusion (CCH) is regarded as a high-risk factor for cognitive decline in vascular dementia (VaD). We have previously shown that diabetes mellitus (DM) synergistically promotes CCH-induced cognitive dysfunction via exacerbating neuroinflammation. Furthermore, curcumin has been shown to exhibit anti-inflammatory and neuroprotective activities. However, the effects of curcumin on CCH-induced cognitive impairments in DM have remained unknown.

Rats were fed with a high-fat diet (HFD) and injected with low-dose streptozotocin (STZ), followed by bilateral common carotid artery occlusion (BCCAO), to model DM and CCH in vivo. After BCCAO, curcumin (50mg/kg) was administered intraperitoneally every two days for eight weeks to evaluate its therapeutic effects. link3 Additionally, mouse BV2 microglial cells were exposed to hypoxia and high glucose to model CCH and DM pathologies in vitro.

Curcumin treatment significantly improved DM/CCH-induced cognitive deficits and attenuated neuronal cell death. Molecular analysis revealed that curcumin exerted protective effects via suppressing neuroinflammation induced by microglial activation, regulating the triggering receptor expressed on myeloid cells 2 (TREM2)/toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) pathway, alleviating apoptosis, and reducing nod-like receptor protein 3 (NLRP3)-dependent pyroptosis.

Taken together, our findings suggest that curcumin represents a promising therapy for DM/CCH-induced cognitive impairments.

CD300a and CD300f play an important role in regulating the function of leukocytes, such as activation, proliferation, differentiation, migration and immunity function. They are considered as potential targets for studying the development and progression of inflammation, infection and other diseases. Here, we review the expression and regulatory mechanisms of CD300a and CD300f on leukocytes, as well as their effects on relevant diseases.The immune system and the nervous system depend on each other for their fine tuning and working, thus cooperating to maintain physiological homeostasis and prevent infections. link3 The cholinergic system regulates the mobilization, differentiation, secretion, and antigen presentation of adaptive and innate immune cells mainly through α7 nicotinic acetylcholine receptors (α7nAChRs). The neuro-immune interactions are established and maintained by the following mechanisms colocalization of immune and neuronal cells at defined anatomical sites, expression of the non-neuronal cholinergic system by immune cells, and the acetylcholine receptor-mediated activation of intracellular signaling pathways. Based on these immunological mechanisms, the protective effects of cholinergic system in animal models of diseases were summarized in this paper, such as myocardial infarction/ischemia-reperfusion, viral myocarditis, and endotoxin-induced myocardial damage. In addition to maintaining hemodynamic stability and improving the energy metabolism of the heart, both non-neuronal acetylcholine and neuronal acetylcholine in the heart can alleviate myocardial inflammation and remodeling to exert a significant cardioprotective effect. The new findings on the role of cholinergic agonists and vagus nerve stimulation in immune regulation are updated, so as to develop improved approaches to treat inflammatory heart disease.

To perform a systematic review and meta-analysis of all randomized controlled trials that examined the efficacy of intraoperative local injection of the uterosacral ligaments with ropivacaine on postoperative pain and opioids consumption in patients undergoing uterine surgery for hysterectomy/myomectomy.

PubMed, Scopus, Web of Science and Cochrane Library databases were screened from inception to September 5th, 2020. We appraised the risk of bias using the Cochrane's risk of bias tool. Resting postoperative pain scores and cumulative consumption of postoperative opioids were regarded as continuous data, analyzed using the inverse variance method and reported as standardized mean difference (SMD) and weighted mean difference (MD), respectively, with 95 % confidence intervals (95 % CIs).

Five studies met the inclusion criteria comprising 230 patients (117 and 113 patients received ropivacaine and placebo, respectively). The studies had an overall low risk of bias. Resting postoperative pain scores were not significantly different between both groups at 2 h (SMD = -0.30, 95 % CI [-0.70, 0.11], p = 0.15), 12 h (SMD = 0.04, 95 % CI [-0.26, 0.37], p = 0.81) and 24 h (SMD = -0.06, 95 % CI [-0.32, 0.20], p = 0.68). However, the ropivacaine group had significantly reduced cumulative opioid consumption during the first 24 h postoperatively (MD = -9.07, 95 % CI [-14.47, -3.66], p = 0.001).

Intraoperative local infiltration of uterosacral ligaments with ropivacaine is technically feasible and significantly reduces postoperative opioid consumption in women undergoing gynecologic surgery of the uterus.

Here, we investigated the relationship between aphantasia and two other neurodevelopmental conditions also linked to imagery differences synaesthesia, and autism. In Experiment 1a and 1b, we asked whether aphantasia and synaesthesia can co-occur, an important question given that synaesthesia is linked to strong imagery. Taking grapheme-colour synaesthesia as a test case, we found that synaesthesia can be objectively diagnosed in aphantasics, suggesting visual imagery is not necessary for synaesthesia to occur. However, aphantasia influenced the type of synaesthesia experienced (favouring 'associator' over 'projector' synaesthesia - a distinction tied to the phenomenology of the synaesthetic experience). In Experiment 2, we asked whether aphantasics have traits associated with autism, an important question given that autism - like aphantasia - is linked to weak imagery. We found that aphantasics reported more autistic traits than controls, with weaknesses in imagination and social skills.
