TL;DR: The micronucleus test using fish peripheral blood has been introduced to assess the contamination of water with some mutagenic chemicals and the sensitivity to detect the clastogenic effects of chemicals could be increased especially after acute treatment.

TL;DR: Improved intracellular penetration of mitochondria-targeted complexes significantly enhanced gene transfer efficiency and delineate a simple and effective peptide-based method, as a starting point for the development of more sophisticated plant mitochondrial transfection strategies.
Abstract: Available methods in plant genetic transformation are nuclear and plastid transformations because similar procedures have not yet been established for the mitochondria. The double membrane and small size of the organelle, in addition to its large population in cells, are major obstacles in mitochondrial transfection. Here we report the intracellular delivery of exogenous DNA localized to the mitochondria of Arabidopsis thaliana using a combination of mitochondria-targeting peptide and cell-penetrating peptide. Low concentrations of peptides were sufficient to deliver DNA into the mitochondria and expression of imported DNA reached detectable levels within a short incubation period (12 h). We found that electrostatic interaction with the cell membrane is not a critical factor for complex internalization, instead, improved intracellular penetration of mitochondria-targeted complexes significantly enhanced gene transfer efficiency. Our results delineate a simple and effective peptide-based method, as a starting point for the development of more sophisticated plant mitochondrial transfection strategies.

TL;DR: In this paper, anodic characteristics of (with ) electrodes were investigated in alkaline solutions and it was found that the catalytic activities for the oxygen evolution reaction are relatively high and that the activity of the electrode with is higher than that of.
Abstract: Anodic characteristics of (with ) electrodes were investigated in alkaline solutions. It was found that the catalytic activities for the oxygen evolution reaction are relatively high and that the activity of the electrode with is higher than that of . The secondary chemical step, i.e., , is rate‐controlling in the oxygen evolution reaction. Therefore, it is concluded that the rate of the secondary chemical step is more rapid at the electrode with the higher value of because of the beneficial effect of the higher positive charge on the Co cation on this step. electrodes are suitable for the anode material in alkaline solutions, because anodic dissolution scarcely occurs.

TL;DR: A ‘scatter-plate microscope’ is proposed and demonstrated that utilizes the diffusing property of the random medium for imaging micro structures with diffraction-limited resolution and provides a light, flexible and cost effective imaging device as an alternative to conventional microscope objectives.
Abstract: Scattering media have always been looked upon as an obstacle in imaging. Various methods, ranging from holography to phase compensation as well as to correlation techniques, have been proposed to cope with this obstacle. We, on the other hand, have a different understanding about the role of the diffusing media. In this paper we propose and demonstrate a ‘scatter-plate microscope’ that utilizes the diffusing property of the random medium for imaging micro structures with diffraction-limited resolution. The ubiquitous property of the speckle patterns permits to exploit the scattering medium as an ultra-thin lensless microscope objective with a variable focal length and a large working distance. The method provides a light, flexible and cost effective imaging device as an alternative to conventional microscope objectives. In principle, the technique is also applicable to lensless imaging in UV and X-ray microscopy. Experiments were performed with visible light to demonstrate the microscopic imaging of USAF resolution test target and a biological sample with varying numerical aperture (NA) and magnifications.
