BACKGROUND The aim of this study was to investigate the expression level of martrilin-3 (MATN3) in patients with gastric adenocarcinoma (GAC) and to investigate the prognostic significance of MATN3. MATERIAL AND METHODS Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) data were used to predict the expression and prognostic value of MATN3 mRNA in GAC patients. Seventy-six GAC pat...

The aim of this work was to separate ethanol in an experimental adsorption–desorption device. We focused on concentrating by adsorption onto granulated activated carbon its gaseous phase, which produced stripping a matrix with different concentrations (2, 5, 10, and 15% v/v). For adsorption, three kinds (GAC) were used, marked as GAC1, GAC2, GAC3. separation product had higher concentration tha...

Vasculogenic mimicry (VM) formation is important for invasion and metastasis of tumor cells in gastric adenocarcinoma (GAC). The present study aimed to investigate the association between signal transducer and activator of transcription-3 (STAT3), phosphor-STAT3 (p-STAT3), hypoxia-inducible factor-1α (HIF-1α) and VM formation in GAC, and discuss their clinical significance and correlation with ...

Five toxicological tests were performed using concentrated drinking water samples collected at a pilot-scale drinking water treatment plant that had streams treated with different disinfectants (no disinfectant, ozone, chlorine dioxide, monochloramine, or chlorine) before treatment with granular activated carbon (GAC). The toxicological tests used in this study were the Ames Salmonella assay, a...

Granular activated carbon (GAC) adsorption has found wide application as a treatment process for the removal of natural organic matter, small compounds (e.g. pesticides), inorganic heavy metals), taste and odour in water over many years. During GAC operation, contaminants are adsorbed becomes progressively saturated time, requiring periodic regeneration media to restore its capacity. Chemical b...

اهداف مهم‌ترین شاخص مؤثر در جذب آلاینده‌های فرّار از هوا، نوع جاذب است. به‌کارگیری جاذبی گزینش‌پذیر، به حذف آلاینده با هزینه کمتر و کارایی بیشتر منجر می‌شود. در این تحقیق، کارایی جاذب اکسیدمنگنز پوشانده‌شده بر سطح کربن فعال (MnO/GAC) برای حذف تولوئن از هوا بررسی شد. همچنین کارایی جاذب MnO/GAC در شرایط آزمایشی یکسان با کربن فعال ساده مقایسه شد. مواد و روش ها جاذب MnO/GAC با روش سل‌ژل تولید شد. زم...

Efficiently making use of granular activated carbon (GAC) to reduce pollution is always a golden goal for water industry. We developed ultrasonication collection method for determination of the biomass and microbial attachment and growth in activated carbon filter. Based on this method, we found that using hydraulic cycle to immobilize cells onto GAC can greatly improve the attachment of inocul...
