A highly electrically conductive linear low-density polyethylene/graphene nanoplate composite with segregated structure (s-LLDPE/GN) was prepared by Yongmei Ma and colleagues through an environmentally friendly method. First, GN coated LLDPE granules were aqueous dispersion, gradually drying. SEM images show that has been successfully on the granule surfaces. Then, s-LLDPE/GN composites obtaine...

The image provided by Tomoya Takada and colleagues shows a cross-sectional SEM micrograph of acrylic denture base resin impregnated with nanodiamond (ND). This study aimed to evaluate the effect ND impregnation on thermal conductivity commercially available resins. It was found that maximum when small amount NDs. colors ND-impregnated resins were also compared using spectrophotometric measureme...

The image created by Guoyan Wang and Jimin He shows the “Jet Flow” phenomenon when UHMWPE melt is ejected from nozzle, on basis of which novel non-dense injection molding proposed to prepare microporous materials with much higher efficiency than traditional powder sintering. In this method, a large number Jet Flow particles produced under high-speed are loosely accumulated bonded in mold cavity...

The Ca(2+) sensor S100A1 is essential for proper endothelial cell (EC) nitric oxide (NO) synthase (eNOS) activation. S100A1 levels are greatly reduced in primary human microvascular ECs subjected to hypoxia, rendering them dysfunctional. However mechanisms that regulate S100A1 levels in ECs are unknown. Here we show that ECs transfected with a S100A1-3' untranslated region (UTR) luciferase repo...

Metastasis is a critical event in the progression of head and neck squamous cell carcinoma (HNSCC). To identify microRNAs associated with HNSCC metastasis, six paired HNSCC cell lines with different metastatic potential were examined. Using microarrays, a panel of differentially expressed microRNAs was identified, including reduction of miR-138 in highly metastatic cells. Ectopic transfection o...

Gastric cancer (GC) is the fourth most predominant malignancy worldwide and remains the second most common cause of cancer-related death globally. Recent studies indicated that miRNAs have been involved in the tumorigenesis pathways in GC. In this study, we investigated the effect and molecular mechanism of miR-138 in human GC. The effects of miR-138 on the GC cell growth and invasion were firs...

LIM kinase 1 (Limk1) is associated with cell prolife-ration and metastasis and its dysregulated expression has been observed in many types of cancer. The present study aimed to examine the role of Limk1 in the development of ovarian cancer, as well as the underlying molecular mechanism involved. The results showed that increased Limk1 and decreased miR-138 expression co-existed in ovarian cance...
