mold powders used in the continuous casting of steel contain the harmful caf2 as a main substance developing toxic gases such as sif4 and hf at elevated temperatures. in this study, three samples of i1, i2 and i3, which contained gypsum free portland cement clinker with different percentages of fe2o3 (5.68, 6.83, 8.02 ) and f- (2.09, 1.06, 0), were prepared and their main characteristics were c...

TOPIC: Critical Care TYPE: Original Investigations PURPOSE: Endotracheal intubation is performed to secure the airway for various elective and emergent indications, including surgeries, respiratory failure, altered mental status1. Currently, supine position most common used endotracheal intubation2. Intubations in non-supine can be necessary many situations, patients with back pain/lesions, inc...

Background: To systematically review perioperative outcomes and postoperative complications between splenectomy plus s-EGDV and n-sEGDV for portal hypertension complicated with thoracic esophageal varices and bleeding by a meta-analysis. Method: We searched the databases of PubMed, the Cochrane Library, Web of Science, EMBASE, TCGA, Chinese Biomedicine Database from January 2000 to June 2017, a...

Objective The purpose of this study was to comprehensively evaluate the effect of short-term exercise intervention on the cardiovascular functions and quality of life (QoL) of patients with chronic heart failure (CHF). Methods This meta-analysis was analyzed using RevMan5.3 and Stata 13.0. The parameters of cardiovascular functions and QoL were assessed. Weighted mean differences and their co...

BACKGROUND We conducted a systematic review to assess the effectiveness of smoking cessation, physical activity (PA), diet, and alcohol reduction interventions delivered by mobile technology to prevent non-communicable diseases (NCDs). METHODS We searched for randomised controlled trials (RCTs) of mobile-based NCD prevention interventions using MEDLINE, EMBASE, Global Health, CINAHL (Jan 1990...

PURPOSE To delineate the role of Sphingolipids (SPLs) in the human cornea and their cross-talks with transforming growth factor beta (TGF-β) in order to develop novel, non-invasive therapies. METHODS Human corneal fibroblasts (HCFs) were harvested from healthy donors, stimulated with Vitamin C to promote extracellular matrix assembly, treated with exogenous sphingosine-1-phosphate (S1P) or sp...

will mean the sum of the values f (i1, i2, ..., ik) over all ”good” k-tuples (i1, i2, ..., ik) ; hereby, a k-tuple (i1, i2, ..., ik) is called ”good” if it satisfies iu ∈ {1, 2, ..., n} for every u ∈ {1, 2, ..., k} and also satisfies all the assertions A1, A2, ..., Al. Using this notation, we can write many typical sums in a simpler form: For instance, ∑ 1≤i≤n f (i) = i ∑ f (i) , and ∑ 1≤i<j≤n ...

Heterogeneity inMeta-analysis of FDG-PET Studies to Diagnose Lung Cancer To the Editor Dr Deppen and colleagues1 conducted a large meta-analysis that showed the limitations of lung cancer diagnosis using fludeoxyglucose F 18 combined with positron emission tomography (FDG-PET) in areas with endemic infectious lung disease. Although the sensitivity and specificity of FDG-PET diagnosis was hetero...

Background Enhanced eosinophil extravasation into the tissue is a characteristic feature of bronchial asthma and other allergic diseases. The barrier-forming vascular endothelial cells release prostaglandin I2 (PGI2, prostacyclin) as the major prostanoid, and it has been previously observed that PGI2 receptor (IP)-deficient mice show enhanced eosinophilic inflammation in response to allergens. ...
