Background/Aims: Duodenitis is not infrequent finding in patient undergoing endoscopy. However, hospitalized patients have a higher incidence of secondary duodenal mucosal lesions that might be related with inflammatory bowel disease (IBD), cytomegalovirus (CMV) infection, tuberculosis, immunologic disorders, or other rare infections. We aimed to identify clinicopathologic features of duodenal mucosal lesions in hospitalized patients. Methods: All hospitalized patients having duodenal mucosal lesions were identified by endoscopic registration data and pathologic data query from 2011 to 2014...

Knee osteoarthritis (OA) is becoming more prevalent worldwide due to increases in the numbers of elderly and obese patients. Currently, pharmaceutical medicines used for the treatment of OA are for symptomatic therapy and therefore new therapeutic agents are needed. Kaempferia parviflora (KP) is a plant growing naturally in Southeast Asia and has various pharmacological effects including an anti-inflammatory effect, but no effect on OA has yet been reported. We therefore conducted a search for the effects KP and the active components of KP extract (KPE) exert on OA as well as its mechanism of action...

Activation of large conductance, calcium-activated potassium (BKCa) channels evokes cell survival programs that mitigate intestinal ischemia and reperfusion (I/R) inflammation and injury 24 hours later. The goal of the current study was to determine the role of reactive oxygen species (ROS) and heme oxygenase (HO)-1 in delayed acquisition of tolerance to I/R induced by pretreatment with the BKCa channel opener NS-1619. Superior mesentery arteries were occluded for 45 min followed by reperfusion for 70 min in wild type (WT) or HO-1 null (HO-1(-/-)) mice that were pretreated with NS-1619 or saline vehicle 24 hrs earlier...

The neuregulin-1 (NRG-1)/ErbB system is an endothelium-controlled paracrine system modulating cardiac performance and adaptation. Recent studies indicate that NRG-1 has anti-fibrotic effects in the left ventricle (LV), which were explained by direct actions on cardiac fibroblasts. However, the NRG-1/ErbB system also regulates the function of macrophages. In this study, we hypothesized that the anti-fibrotic effect of NRG-1 in the heart is at least partially mediated through inhibitory effects on macrophages...

INTRODUCTION: Inflammatory bowel diseases (IBD) are immune-mediated disorders that result from an aberrant immunological response to the gut luminal antigen in genetically susceptible patients. IBD is categorized into two serotype, Crohn's diseases (CD) and ulcerative colitis (UC), both subtype are important cause of gastrointestinal diseases. The increasing rate of hospitalization, with the high economic burden experienced by the IBD patients, calls for more concerted research efforts to design a potent and affordable treatment option for the treatment of IBD...

OBJECTIVES: Amelogenin, the major component of the enamel matrix derivative (EMD), has been suggested as a bioactive candidate for periodontal regeneration. Apart from producing a regenerative effect on periodontal tissues, amelogenin has also been reported to have an anti-inflammatory effect. However, the precise molecular mechanisms underlying these effects remain unclear. In the present study, we examined the immunomodulatory effects of amelogenin on macrophages. DESIGN: Human phorbol 12-myristate 13-acetate (PMA)-differentiated U937 macrophages and CD14+ peripheral blood-derived monocytes (PBMC)-derived macrophages were stimulated with recombinant amelogenin (rM180)...

Obstructive sleep apnea (OSA), characterized by chronic intermittent hypoxia (CIH), is associated with endothelial dysfunction. The prevalence of OSA is linked to an epidemic of obesity. CIH has recently been reported to cause endothelial dysfunction in diet-induced obese animals by exaggerating oxidative stress and inflammation, but the underlying mechanism remains unclear. PPAR-γ, a ligand-inducible transcription factor that exerts anti-oxidant and anti-inflammatory effects, is down-regulated in the peripheral tissues in diet-induce obesity...

BACKGROUND: Cardiac sarcoidosis is associated with major adverse cardiac events including cardiac arrest, for which anti-inflammatory treatment is indicated. Oral corticosteroid is the mainstay among treatment options; however, adverse effects are a major concern with long-term use. It would be beneficial for providers to predict treatment response and prognosis for proper management strategy of sarcoidosis, though it remains challenging. Fluorine (F)-18 fluorodeoxyglucose (FDG)-positron emission tomography(PET)/computed tomography(CT) has an advantage over anatomical imaging in providing semi-quantitative functional parameters such as standard uptake value (SUV), metabolic volume, and total lesion glycolysis (TLG), which are well-established biomarkers in oncology...

Oligodendrocytes, the myelin-producing cells of the central nervous system (CNS), have limited capability to bring about repair in chronic CNS neuroinflammatory demyelinating disorders such as multiple sclerosis (MS). MS lesions are characterized by a compromised pool of undifferentiated oligodendrocyte progenitor cells (OPCs) unable to mature into myelin-producing oligodendrocytes. An attractive strategy may be to replace lost OLs and/or promote their maturation. N-palmitoylethanolamine (PEA) is an endogenous fatty acid amide signaling molecule with anti-inflammatory and neuroprotective actions...

The cholinergic anti-inflammatory pathway is recognized as one of the main mechanisms of neuromodulation of the immune system. Activation of the α7 nicotinic acetylcholine receptor (nAchRα7) suppresses cytokine synthesis in distinct immune cells but the molecular mechanisms behind this effect remain to be fully described. Mast cells (MCs) are essential players of allergic reactions and innate immunity responses related to chronic inflammation. Activation of TLR4 receptor in MCs leads to the rapid secretion of pre-synthesized TNF from intracellular pools and to the activation of NFκB, necessary for de novo synthesis of TNF and other cytokines...

Gypenoside IX (GP IX) is a pure compound isolated from Panax notoginseng. Gypenosides have been implicated to benefit the recovery of enormous neurological disorders. By suppressing the activation of astrocytes, gypenosides can improve the cognitive impairment. However, so far, little is known about whether GP IX could restrain the inflammatory responses in astrocytes or reactive astrogliosis. In present study, the anti-inflammatory effects of GP IX were investigated in reactive astrocytes induced by proinflammatory mediators both in vitro and in vivo...
