Introduction: Individual grains and small lithic clasts in thin-sectioned suevitic breccia samples from the International Continental Scientific Drilling Program (ICDP) Bosumtwi impact crater drillcore LB07A were examined petrographically to evaluate the occurrence , abundance, and characteristics of unshocked and shock-metamorphosed quartz. The analyzed samples were taken across a ~42-m-long (...

BACKGROUND MiR-138 is frequently downregulated in different cancer types and is thought to be involved in the progression of tumorigenesis. However, the molecular mechanism of miR-138 involvement in gallbladder carcinoma still remains unknown. METHODS The expression of miR-138 in 49 gallbladder carcinoma samples and paired normal gallbladder samples was analyzed using quantitative reverse tra...

PURPOSE Constitutive activation of NF-κB signaling plays vital roles in esophageal squamous cell carcinoma (ESCC) progression. The aim of this study was to evaluate the effect of miR-138 on NF-κB activation and ESCC progression. EXPERIMENTAL DESIGN Expression of miR-138 in ESCC cell lines, ESCC tissues, and 205 archived ESSC specimens was determined using real-time PCR analysis. Anchorage-ind...

BACKGROUND/AIMS MicroRNAs (miRNAs) play important roles in tumorigenesis. We investigated the roles and mechanisms of miR-138 in human non-small cell lung cancer (NSCLC). METHODS The expression of miR-138 was first examined in NSCLC cell lines and tumour tissues by real-time PCR The in vitro and in vivo functional effect of miR-138 was examined further. A luciferase reporter assay was conduct...

MicroRNA (miR)-138 generally has a suppressive role in various human cancer types; however, its role and the underlying mechanisms in laryngeal squamous cell carcinoma (LSCC) have remained to be elucidated. The present study assessed the clinical significance and regulatory mechanisms of miR-138 in LSCC progression. Reverse-transcription quantitative polymerase chain reaction analysis indicated...

It is widely recognized that global warming promotes soil organic carbon (SOC) decomposition, and soils thus emit more CO2 into the atmosphere because of the warming; however, the response of SOC decomposition to this warming in different soil textures is unclear. This lack of knowledge limits our projection of SOC turnover and CO2 emission from soils after future warming. To investigate the CO...
