Tension-Tension Fatigue Behavior of High-Toughness ZrTiCuAl Bulk Metallic Glass.

Bulk metallic glasses have application potential in engineering structures due to their exceptional strength and fracture toughness. Their fatigue resistance is very important for the application as well. We report the tension-tension fatigue damage behavior of a ZrTiCuAl bulk metallic glass, which has the highest fracture toughness among BMGs.

Detailed analysis of inflammatory cell infiltration and the prognostic impact on nasopharyngeal carcinoma.

Background: One of the most striking characteristics of nasopharyngeal carcinoma (NPC) is the presence of a very abundant immune cells infiltrate containing mainly T-lymphocytes. The purpose of this study was to present our analysis providing a comprehensive characterization of antitumor inflammatory response in NPC.

Methods: The densities of 9 types of inflammatory cells were assessed in 197 patients with NPC, including CD3 + T-lymphocytes, CD8 + cytotoxic T-lymphocytes, CD20 + B-lymphocytes, CD56 + natural killer (NK) cells, FOXP3 + regulatory T-lymphocytes, CD1a + immature dendritic cells, CD83 + mature dendritic cells, neutrophil elastase + neutrophils, and tryptase + mast cells.

Levels of plasma Epstein-Barr virus DNA prior and subsequent to treatment predicts the prognosis of nasopharyngeal carcinoma.

The level of Epstein-Barr virus DNA (EBV-DNA) in the plasma prior and subsequent to treatment is a reliable biomarker for the screening, diagnosis, monitoring and prognosis of nasopharyngeal carcinoma (NPC). The present retrospective study aimed to determine whether pre- and post-treatment levels of plasma EBV-DNA were predictive of survival in a large sample of patients with NPC. The level of plasma EBV-DNA in 637 NPC patients prior and subsequent to treatment was determined by quantitative polymerase chain reaction.

MiR-124 suppresses tumor growth and metastasis by targeting Foxq1 in nasopharyngeal carcinoma.

Background: The molecular mechanisms underlying dysregulation of microRNAs have been documented in nasopharyngeal carcinoma (NPC). Our previous study demonstrated that plasma miR-124 was down-regulated in NPC using microarray analysis and quantitative PCR validation. Though growing studies showed that down-regulated miR-124 was closely related to tumourigenesis in various types of cancers, the role of miR-124 in NPC remains largely unknown.
