The Guizhou gastromyzontidae (Beaufortia kweichowensis) can adhere to slippery and fouled surfaces in torrential streams. A unique adhesive system utilized by the fish was observed by microscope and CLSM as an attachment disc sealed by a round belt of micro bubbles. The system is effective in wet or underwater environments and can resist a normal pulling force up to 1000 times the fish's weight...

Manipulation of DNA fibers is very useful technique for gene analysis such as Fluorescent In Situ Hybridization (FISH). In conventional methods for manipulation of DNA fibers, FISH efficiency often decreases due to the tight adhesion between DNA fibers and substrates. In this paper, we propose a micro glass-phonorecord with concentric grooves for suspending DNA fibers with centrifugal force. As...

Through the analysis of macro- and micro-plant remains, food residues rice-field like features from mid-Neolithic site Hanjing in Huai River region, we propose an early beginning rice cultivation at Hanjing. The presence non-shattering spikelet bases increasing percentages phytoliths confirm appearance domesticated archaeobotanical assemblage. However, as indicated by different prediction rates...

noncoding ribonucleic acids micro-rna is involved in the regulation of gene expression have major roles in the post-transcriptional level. a micro-rna alone several causes down regulation of mrna transcript of the target. thus, small changes in the expression of a micro rna may lead to significant changes in gene expression are different. micro- rna as key regulators of immune cell lineage diff...
