OBJECTIVE(S): Many patients with Essure® implant may experience adverse events related to the device. Although local inflammation does not appear to be the pathophysiological mechanism underlying the symptoms, systemic inflammation could play a role. In the present study, as cytokines are involved in the inflammatory process, we proposed to investigate the profile of circulating and peritoneal cytokines. STUDY DESIGN: In this retrospective study, we evaluated the levels of cytokines in peritoneal fluid (PF) as well as in plasma sample from three different groups: Essure® group, endometriosis group (known to be associated with immune dysregulation), and control group...

BACKGROUND/INTRODUCTION: Adipose tissue (AT) has been highlighted as a promising reservoir of infection for viruses, bacteria and parasites. Among them is Trypanosoma cruzi , which causes Chagas disease. The recommended treatment for the disease in Brazil is Benznidazole (BZ). However, its efficacy may vary according to the stage of the disease, geographical origin, age, immune background of the host and sensitivity of the strains to the drug. In this context, AT may act as an ally for the parasite survival and persistence in the host and a barrier for BZ action...

PURPOSE: Rhegmatogenous retinal detachment is a severe vision-threatening complication that can result into proliferative vitreoretinopathy (PVR) and re-detachment of the retina if recovery from surgery fails. Inflammation and changes in retinal pigment epithelial (RPE) cells are important contributors to the disease. Here, we studied the effects of simvastatin and amfenac on ARPE-19 cells under inflammatory conditions. METHODS: ARPE-19 cells were pre-treated with simvastatin and/or amfenac for 24 h after which interleukin (IL)-1α or IL-1β was added for another 24 h...

BACKGROUND: Chronic low-grade inflammatory profile (CLIP) is one of the pathways involved in type 2 diabetes (T2D). Currently, there is limited evidence for ameliorating effects of combined lifestyle interventions on CLIP in type 2 diabetes. We investigated whether a 13-week combined lifestyle intervention, using hypocaloric diet and resistance exercise plus high-intensity interval training with or without consumption of a protein drink, affected CLIP in older adults with T2D. METHODS: In this post-hoc analysis of the PROBE study 114 adults (≥55 years) with obesity and type 2 (pre-)diabetes had measurements of C-reactive protein (CRP), pro-inflammatory cytokines interleukin (IL)-6, tumor-necrosis-factor (TNF)-α, and monocyte chemoattractant protein (MCP)-1, anti-inflammatory cytokines IL-10, IL-1 receptor antagonist (RA), and soluble tumor-necrosis-factor receptor (sTNFR)1, adipokines leptin and adiponectin, and glycation biomarkers carboxymethyl-lysine (CML) and soluble receptor for advanced glycation end products (sRAGE) from fasting blood samples...

BACKGROUND: Prosthodontics are often performed to treat patients with malocclusion and dentition defects. However, single prosthodontics cannot properly correct the disharmony of teeth, dental arch and other parts affected by malocclusion, and some patients may have difficulty in recovering the occlusal function due to poor prosthodontics. OBJECTIVE: This study aims to investigate the effect of orthodontics combined with fibre-reinforced composite resin-bonded fixed partial denture (FRC-RBFPD) on anterior dentition defects with minimal vertical intermaxillary space...

Objective To investigate the effect of 3-deazaadenosine (3-DAA), an N6 -methyladenosine (m6 A) methylation modification inhibitor, on the replication of the Japanese encephalitis virus (JEV). Methods Neuro2a mouse neuroblastoma cells, N9 mouse microglial cells, and BHK baby hamster kidney cells were exposed to JEV and then treated with 3-DAA. JEV was also injected into the footpad of adult C57BL/6 mice, which were then administered 3-DAA intraperitoneally. Real-time quantitative PCR was utilized to measure mRNA expression levels of JEV, interleukin 1β (IL-1β), IL-6, tumor necrosis factor α (TNF-α), monocyte chemoattractant protein 1 (MCP-1), inducible nitric oxide synthase (iNOS), arginase 1 (Arg1), interferon (IFN)-α, IFN-β, IFN-γ, and C-X-C motif chemokine ligand 10 (CXCL10) in the cells and mouse brain tissues...

Objective To compare the functional differences between bone marrow derived macrophages and peritoneal macrophages, which may provide the basis for the selection of macrophages in immunological research and immunoregulatory drug evaluation. Methods Marophage colony-stimulating factor (M-CSF) was used to induce the differentiation of bone marrow monocytes into macrophages, and thioglycolate medium was used to induce peritonitis to obtain peritoneal macrophages. After both macrophages being stimulated by zymosan, LPS, R848 and CpG respectively, mRNA levels of tumor necrosis factor α(TNF-α), interleukin 6(IL-6), macrophage inflammatory protein 1α(MIP-1α), monocyte chemoattractant protein 1(MCP-1) were measured by Real-time fluorescent quantitative PCR and the concentrations of secreted TNF-α, IL-6, MIP-1α and MCP-1 were detected by ELISA...

AIMS: Substantial evidence emphasizes immune dysregulation in patients with bipolar disorder (BD). However, whether immune dysregulation is present already in the early illness stages of BD or even precedes development of BD is largely unknown. In this study we compared immune and vascular stress markers in patients newly diagnosed with BD, their unaffected first-degree relatives (UR) and healthy control individuals (HC) and investigated the ability a composite immune and vascular stress marker to discriminate between the three groups of participants...

PURPOSE: To identify predictive factors for satisfactory treatment outcome of the patients with IC/BPS using urine biomarkers and machine-learning models. METHODS: The IC/BPS patients were prospectively enrolled and provide urine samples. The targeted analytes included inflammatory cytokines, neurotrophins, and oxidative stress biomarkers. The patients with overall subjective symptom improvement of ≥ 50% were considered to have satisfactory results...

INTRODUCTION: Sepsis represents a critical medical condition that arises due to an imbalanced host reaction to infection. Central to its pathophysiology are cytokines. However, observational investigations that explore the interrelationships between circulating cytokines and susceptibility to sepsis frequently encounter challenges pertaining to confounding variables and reverse causality. METHODS: To elucidate the potential causal impact of cytokines on the risk of sepsis, we conducted two-sample Mendelian randomization (MR) analyses...

OBJECTIVE: To examine the nephroprotective mechanism of modified Huangqi Chifeng decoction (, MHCD) in immunoglobulin A nephropathy (IgAN) rats. METHODS: To establish the IgAN rat model, the bovine serum albumin, lipopolysaccharide, and carbon tetrachloride 4 method was employed. The rats were then randomly assigned to the control, model, telmisartan, and high-, medium-, and low-dose MHCD groups, and were administered the respective treatments via intragastric administration for 8 weeks...

Enlarged perivascular spaces have been previously reported in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, but their significance and pathophysiology remains unclear. We investigated associations of white matter enlarged perivascular spaces with classical imaging measures, cognitive measures and plasma proteins to better understand what enlarged perivascular spaces represent in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy and whether radiographic measures of enlarged perivascular spaces would be of value in future therapeutic discovery studies for cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy...

AIMS: Previous studies have demonstrated a significant upregulation of Integrin Beta 1 (ITGB1) in Telocytes. This study aims to explore the roles and underlying mechanisms of ITGB1 in inflammation and oxidative stress following Lipo-polysaccharide (LPS) administration in Telocytes. METHODS: We observed an increase in reactive oxygen species (ROS) production, accompanied by a reduction in ITGB1 levels post-LPS treatment. RESULTS: Notably, inhibiting ROS synthesis markedly reduced LPS-induced ITGB1 expression...

INTRODUCTION: Benign prostatic hyperplasia (BPH) is a histopathological diagnosis characterized by the increase in stromal cells and epithelial cells of the prostate gland in the transitional zone surrounding the urethra. Obesity is the risk factor of BPH. The most frequent cause of obesity is a high-fat diet (HFD). Obesity and HFD lead to pro-inflammatory conditions. One of the pathomechanisms for the occurrence of BPH is a low-degree inflammatory factor, one of which is the level of monocyte chemoattractant protein-1/MCP-1...

Vascular endothelial growth factor (VEGF) induces monocyte chemoattractant protein-1 (MCP-1) and plays an important role in vascular inflammation and atherosclerosis. We investigated the mechanisms of VEGF-induced MCP-1 expression and the effects of eicosapentaenoic acid (EPA) in human umbilical vein endothelial cells (HUVECs). Real-time reverse transcription polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA) demonstrated that VEGF enhanced MCP-1 gene expression and protein secretion in HUVECs...

Transcription factor NRF2 is involved in inflammatory reactions, maintenance of redox balance, metabolism of xenobiotics, and is of particular interest for studying aging. In the present work, the CRISPR/Cas9 genome editing technology was used to generate the NRF2ΔNeh2 mice containing a substitution of eight amino acid residues at the N-terminus of the NRF2 protein, upstream of the functional Neh2 domain, which ensures binding of NRF2 to its inhibitor KEAP1. Heterozygote NRF2wt/ΔNeh2 mice gave birth to homozygous mice with lower than expected frequency, accompanied by their increased embryonic lethality and visual signs of anemia...

OBJECTIVE: To investigate profiles of circulating immune signatures in healthy controls and chronic pancreatitis patients (CP) with and without a preceding history of acute pancreatitis (AP). METHODS: We performed a phase 1, cross-sectional analysis of prospectively collected serum samples from the PROspective Evaluation of Chronic Pancreatitis for EpidEmiologic and Translation StuDies (PROCEED) study. All samples were collected during a clinically quiescent phase...

INTRODUCTION: Despite older adults being more vulnerable to sepsis, most preclinical research on sepsis has been conducted using young animals. This results in decreased scientific validity since age is an independent predictor of poor outcome. In this study, we explored the impact of aging on the host response to sepsis using the fecal-induced peritonitis (FIP) model developed by the National Preclinical Sepsis Platform (NPSP). METHODS: C57BL/6 mice (3 or 12 months old) were injected intraperitoneally with rat fecal slurry (0...

Streptococcus suis is an emerging zoonotic pathogen that can cause invasive disease commonly associated with meningitis in pigs and humans. To cause meningitis, S. suis must cross the blood-brain barrier (BBB) comprising blood vessels that vascularize the central nervous system (CNS). The BBB is highly selective due to interactions with other cell types in the brain and the composition of the extracellular matrix (ECM). Purified streptococcal surface enolase, an essential enzyme participating in glycolysis, can bind human plasminogen (Plg) and plasmin (Pln)...
