objective(s):cyclophosphamide (cp) toxicity on testis was hampered by squid ink polysaccharide (sip) via restoration of antioxidant ability in our previous investigations. this study investigated roles of nrf2/are signal pathway in testis of treated mice. materials and methods: male kunming mice were employed to undergo treatment with sip and/or cp. protein levels of nrf2, keap-1, histone deace...

UV printing is different from conventional printing in many ways. It is still ink on paper but the ink dries through a completely different process. Instead of having solvents in the ink that evaporate into the air and absorb into the paper, UV inks dry through a photomechanical process. When the inks are exposed to ultraviolet lights they turn from a liquid, or paste, to a solid. There is sign...

The basic deinking process for old newspapers, the role of the deinking agent, the science and the condition for good deinking are reviewed based on the results in our laboratory first. Then, by using this typical deinking process, the deinkability of the pigment―based inkjet printings was examined. In commercial printings, the transition to on―demand printings is in progress, because the on―de...

We present the fabrication and characteristics of monolithically integrated ink dyed poly(dimethylsiloxane) (PDMS) filters for optical sensing in disposable lab-on-a-chip. This represents a migration of auxillary functions onto the disposable chip with the goal of producing truly portable systems. Filters made from commercially available ink (Pelikan) directly mixed into PDMS oligomer without t...

The intention of this research was to investigate the ink diffusion that takes place in dip-pen nanolithography in order to better understand how to enhance the possibilities of nano fountain probes. Varying concentrations of 16-mercaptohexadecanoic acid in ethanol were used as ink in dip-pen nanolithography, and the relationships between contact time, concentration, and ink diffusion were stud...

Original scientific paper A different number of white ink layers printed with the inkjet technology can influence the legibility of prints. Therefore, we tested how to achieve best legibility of printed text and labelling information, considering the changes in colorimetric and typographic properties. The prints were made with an inkjet printer and three different numbers of white ink layers we...

The analysis of inks and the paper to which they are applied is of great interest to a broad spectrum of science. From the historian and archaeologist to the forensic scientist, an understanding of ink-paper interactions is essential to the understanding of the ink and its subsequent changes upon application to paper. Determining chemical and other details of ink in a signature, for example, ca...

1. A behavioral and electrophysiological analysis of defensive ink release in Aplysia californica was performed to examine the response of this behavior and its underlying neural circuit to various-duration noxious stimuli. 2. Three separate behavioral protocols were employed using electrical shocks to the head as noxious stimuli to elicit ink release. Ink release was found to be selectively re...
