Eosinophils play a major pathologic role in the pathogenesis of diverse inflammatory diseases including chronic rhinosinusitis (CRS). Dysregulated production of prostaglandin (PG), particularly PGD2, is considered to be an important contributing factor to eosinophilic inflammation in CRS primarily through proinflammatory and chemotactic effects on eosinophils. Here, we provide evidence that PGD...

Análise estática do posicionamento do sistema de cinco pontos em dispositivos de retenção infantil Abstract The present study examines several important contributors to appropriate child restraint systems (CRS), including harness routing (chest and lap straps) and the location of important protective components. Three forward-facing CRS equipped with five-point harnesses were evaluated in a lab...

OBJECTIVES To understand the formal roles of community representatives (CRs) in Clinical and Translational Science Awardee (CTSA) activities, to evaluate the extent of integration into the organizational and governance structures and to identify barriers to effective integration. METHODS The inventory tool was distributed to each of the 60 CTSAs using a secure web application. RESULTS Forty...

BACKGROUND The diagnosis of chronic rhinosinusitis (CRS) based on clinical presentation alone remains challenging. To improve the accuracy of clinical diagnosis, the Canadian Rhinosinusitis Guidelines recommend the use of specific symptom and endoscopic criteria. Our study objective was to determine whether symptom and endoscopic criteria, as defined by the Canadian Rhinosinusitis Guidelines, a...

Coexistence of chronic rhinosinusitis (CRS) with asthma appears to impair asthma control. Type-2 innate lymphoid cells (ILC2s) respond to the cytokines of thymic stromal lymphopoietin (TSLP), interleukin (IL)-25 and IL-33, thus contributing to airway diseases such as CRS and asthma. We investigate whether the augmented Th2-cytokines in CRS might be related to sinonasal tract ILC2s corresponding...

BACKGROUND This study was conducted to assess the effect of comorbidity, ethnicity, occupation, smoking and place of residence on allergic rhinitis (AR), acute rhinosinusitis (ARS) and chronic rhinosinusitis (CRS). METHODS A GA2LEN (The Global Allergy and Asthma European Network) screening questionnaire was sent to a random sample of the Dutch population (n = 16700) in three different areas o...

Chromatin remodeling mediated by histone acetylation might be involved in the pathophysiology and the treatment of depression. Recently, it has been reported that the histone deacetylase (HDAC) inhibitors, such as sodium butyrate (SB), could be a potential therapeutic agent for depression treatment. In the present study, we aimed to clarify the antidepressant mechanism of SB in the hippocampus....

Many aging male suffer various andropause symptoms including loss of physical and mental activities. This study evaluated the putative alleviative effects of CRS-10 dandelion and rooibos extract complex (CRS-10) on the symptoms of andropause. The survival rate of TM3 Leydig cells (TM3 cells) treated with CRS-10 was measured based on typical physiological stress. After daily intake of CRS-10 for...

Pathophysiological mechanisms of cardiorenal syndromes (CRS) types 1-5 are still sparsely characterized. In an attempt to address this issue, a consensus conference on CRS was held in Venice, Italy, in November 2012 under the auspices of the Acute Dialysis Quality Initiative (ADQI). Working group 1 discussed monodirectional mechanisms of CRS type 1 which is characterized by a rapid worsening of...

BACKGROUND Several studies have reported that chronic rhinosinusitis (CRS) increases the risk of stroke. The aim of this study is to elucidate the putative association between CRS and stroke (ischemic or hemorrhagic) using large population-based national health insurance data. METHODS Using the national cohort study from the Korean Health Insurance Review and Assessment Service, CRS patients ...
