We have carried out convenient and highly sensitive radon measurement using absorption to means of a detecting active charcoal and a liquid scintillation spectrometer, Packard Pico-rad System. The α and β radioactivities of its decay products originated from radon gas absorbed detector exposed to air were measured. Its detection limit is 1.7Bq/m in air with an accuracy of about 10% on 200 minit...

MicroRNAs are short regulatory RNAs that negatively modulate protein expression at a post-transcriptional level. Emerging evidence suggests that altered regulation of miRNA may be involved in the pathogenesis of several types of cancers. In the current study, an inverse relationship between the expression of miR-221/miR-222 and the cell cycle inhibitor p27Kip1 was identified in U251 glioma cell...

OBJECTIVE To determine if repletion of hemoglobin was achievable in young children presenting both severe (< or =9.4 g hemoglobin/dL blood) and less severe iron deficiency anemia (9.5 to 11.0 g hemoglobin/dL blood) through fortification of liquid 3.3% butterfat milk with a bioavailable ferrous iron amino acid chelate (Ferrochel) at 3 mg iron/liter/day. METHODS A group of 185 children were sel...

ARHI is an imprinted tumor suppressor gene and is downregulated in various malignancies. However, ARHI expression, function, and mechanisms of action in prostate cancer have not been reported. Here, we report that ARHI mRNA and protein levels were downregulated in prostate cancer tissues compared with adjacent normal tissues. Overexpression of ARHI inhibited cell proliferation, colony formation...

MicroRNAs (miRNAs) are potent negative regulators of gene expression involved in all aspects of cell biology. They finely modulate virtually all physiological pathways in metazoans, and are deeply implicated in all main pathologies, among which cancer. Mir-221 and miR-222, two closely related miRNAs encoded in cluster from a genomic region on chromosome X, are strongly upregulated in several fo...

Atmospheric radon ((222)Rn) and carbon dioxide (CO2) concentrations were used to gain insight into fugitive emissions in an Australian coal seam gas (CSG) field (Surat Basin, Tara region, Queensland). (222)Rn and CO2 concentrations were observed for 24 h within and outside the gas field. Both (222)Rn and CO2 concentrations followed a diurnal cycle with night time concentrations higher than day ...

MicroRNAs (miRNAs) are small non-coding RNAs that play a mostly post-transcriptional regulatory role in gene expression. Using RAW264.7 pre-osteoclast cells and genome-wide expression analysis, we identified a set of miRNAs that are involved in osteoclastogenesis. Based on in silico analysis, we specifically focused on miR-222-3p and evaluated its role in osteoclastogenesis. The results show th...
