Ischemic stroke is a complex brain injury caused by a thrombus or embolus obstructing blood flow to parts of the brain. This leads to deprivation of oxygen and glucose, which causes energy failure and neuronal death. After an ischemic stroke insult, astrocytes become reactive and proliferate around the injury site as it develops. Under this scenario, it is difficult to study the specific contribution of astrocytes to the brain region exposed to ischemia. Therefore, this article introduces a methodology to study primary astrocyte reactivity and proliferation under an in vitro model of an ischemia-like environment, called oxygen glucose deprivation (OGD)...

A cytotoxicity study was conducted with a primary culture of the nervous system cells, including brain microvascular endothelial cells (BMECs) and astrocytes, which are important components of the blood-brain barrier. The real-time cell analysis (RTCA) was used to determine the cytotoxicity of copper-oxide nanoparticles (CuO NPs). The IC50 values of CuO NPs in astrocytes and BMECs were determined by the RTCA at different exposure times and were used as base values for further research. DNA damage after exposure to CuO NPs for 3 and 24 h was assessed using comet assay at the IC50 obtained from RTCA...

Lactoperoxidase (Lpo) and Lactoferrin (Lf) were extracted from camel colostrum milk and purified. The antibacterial activity of the two purified proteins was estimated against 14 isolates of multidrug resistance Acinetobacter baumannii. A combination of Lpo and Lf exhibited bactericidal action against A. baumannii in vitro. A mouse model of acute A. baumannii pneumonia was improved. The injection of combined Lpo and Lf after infection leads to significant clearance of A. baumannii rates in lung as well as blood culture P < 0...

BACKGROUND AND AIMS: Accumulating studies indicate that miR-150-5p might play a significant role in dendritic cells (DCs) of peripheral blood in chronic rhinosinusitis (CRS) patients. We sought to investigate the effects and mechanism of miR-150-5p, which regulates early growth response 2 (EGR2) to promote the development of CRS via the DC-Th axis. METHODS: The upregulated expression of miR-150-5p in DCs of CRS was assayed by real-time quantitative polymerase chain reaction (qRT-PCR), and IL-17 cytokines in the supernatants of DC-naïve T cells co-cultures were analysed by enzyme-linked immunosorbent assay (ELISA)...

In England and Wales, approximately one half of all laboratory-confirmed meningococcal disease cases fail to yield a viable invasive isolate, primarily due to the use of antibiotics. Characterisation of non-culture meningococci has been restricted to the detection or sequencing of specific gene targets within clinical specimens. In this study we investigated the ability of the Agilent SureSelectXT kit to facilitate DNA enrichment and genome sequencing of meningococcal DNA within a small panel of blood and CSF specimens...

OBJECTIVES: Staphylococcus aureus bacteremia (SAB) is an important cause of morbidity and mortality. Suboptimal treatment has been associated with poor patient outcomes. Our antimicrobial stewardship program (ASP) evaluated SAB management based on predefined performance measures both prior to and after instituting a "care package" intervention led by clinical pharmacists and infectious diseases physicians. The primary outcome included a 4-point "optimal care score" (OCS) consisting of targeted antibiotic therapy within 24hours, repeating blood cultures, antibiotic duration assessment, and appropriate duration of therapy...

Infection is the main problem among the patients receiving cancer therapy. The mortality rate can be reduced by the appropriate treatment in the right time. Although blood culture is the gold standard for the diagnoses of sepsis, many factors influence the results of blood culture in children. For this reason, real time polymerase chain reaction (Rt-PCR) has gained importance for the diagnoses of microbiological agents as it is faster than the conventional methods. In this study, we aimed to compare the efficacy of SeptiFast (SF) test with blood culture among children with neutropenic fever...

OBJECTIVE: There is increasing data in pediatrics demonstrating procalcitonin (PCT) is more sensitive and specific than other biomarkers in the setting of bacterial infections. However, the use of PCT in neonatal and pediatric extracorporeal membrane oxygenation (ECMO) is not well described. Therefore, the purpose of this study was to describe the clinical utility of PCT in determining the absence or presence of bacterial infections in neonatal and pediatric patients on ECMO. METHODS: This was a retrospective electronic medical record (EMR) review of data between January 1, 2010 to June 30, 2016 at a single, free-standing, children 's hospital...

AIM: In vivo vascular smooth muscle cell (VSMC) EGF receptor (EGFR) contributes to acute angiotensin II (AII) effects on vascular tone and blood pressure. The ubiquitously expressed EGFR has been implicated in vascular remodeling preceding end-organ damage by pharmacological inhibition, and AII signaling in cultured vascular cells is partly EGFR dependent. However the role of VSMC-EGFR in vivo during AII-induced pathophysiological processes is not known. METHODS: The present study assesses the in vivo relevance of VSMC-EGFR during chronic AII challenge without further stressors, using a mouse model with inducible, VSMC-specific EGFR knock out (VSMC-EGFR-KO)...

Immunodeficient mice engrafted with human peripheral blood cells are promising tools for in vivo analysis of human patient individual immune responses. However, when human peripheral blood mononuclear cells (PBMCs) are transferred into NOG (NOD/Shi-scid, IL-2rg(null)) mice, severe graft versus host disease (GVHD) hinders long term detailed analysis. Administration of human PBMCs into newly developed murine MHC class I- and class II-deficient NOG (NOG-dKO; NOG- Iab, B2m-double-knockout) mice showed sufficient engraftment of human immune cells with little sign of GVHD...

PURPOSE: Uremic toxins produced by gut microbiota (indoxyl sulfate-IS, p-cresyl sulfate-p-CS, and indole-3-acetic acid-IAA) accumulate in hemodialysis (HD) patients and exhibit potent inflammatory effects. However, the impact of these toxins on nuclear E2-related factor 2 (Nrf2) and nuclear factor-kappa B (NF-κB) expression in HD patients remains poorly defined. The aim of this study was to evaluate the association between uremic toxins and Nrf2/NF-κB expression in vitro (RAW 264.7 macrophage-like cells) and in peripheral blood mononuclear cells from HD patients...
