Sediment resuspension as a driving force for organic carbon transference and rebalance in marginal seas.

The transfer of particulate organic carbon (POC) to dissolved organic carbon (DOC; OC transfer) is crucial for the marine carbon cycle. Sediment resuspension driven by hydrodynamic forcing can affect the burial of sedimentary POC and benthic biological processes in marginal sea. However, the role of sediment grain size fraction on OC transfer and the subsequent impact on OC cycling remain unknown.

Synthesis, Characterization, DNA/HSA Interactions, and Anticancer Activity of Two Novel Copper(II) Complexes with 4-Chloro-3-Nitrobenzoic Acid Ligand.

The purpose of this study was to identify new metal-based anticancer drugs; to this end, we synthesized two new copper(II) complexes, namely [Cu(ncba)(phen)] () and [Cu(ncba)(bpy)] (), comprised 4-chloro-3-nitrobenzoic acid as the main ligand. The single-crystal XRD approach was employed to determine the copper(II) complex structures. Binding between these complexes and calf thymus DNA (CT-DNA) and human serum albumin (HSA) was explored by electronic absorption, fluorescence spectroscopy, and viscometry.

In Vivo Radioprotective Activity of Cell-Permeable Bifunctional Antioxidant Enzyme GST-TAT-SOD against Whole-Body Ionizing Irradiation in Mice.

GST-TAT-SOD was the fusion of superoxide dismutase (SOD), cell-permeable peptide TAT, and glutathione-S-transferase (GST). It was proved to be a potential selective radioprotector in vitro in our previous work. This study evaluated the in vivo radioprotective activity of GST-TAT-SOD against whole-body irradiation.

[The Research and Application of Transient Temperature Test Based on Apodized-Chirped FBG].

In order to quickly and accurately obtain the transient temperature field information of the barrel when the gun is firing, the transient temperature measurement system was designed with apodized-chirped fiber Bragg grating (FBG) probe. In the system, chirped fiber grating was used to modulate the bandwidth of echo light. The bandwidth of echo light had been greatly improved.

GST-TAT-SOD: Cell Permeable Bifunctional Antioxidant Enzyme-A Potential Selective Radioprotector.

Superoxide dismutase (SOD) fusion of TAT was proved to be radioprotective in our previous work. On that basis, a bifunctional recombinant protein which was the fusion of glutathione S-transferase (GST), SOD, and TAT was constructed and named GST-TAT-SOD. Herein we report the investigation of the cytotoxicity, cell-penetrating activity, and in vitro radioprotective effect of GST-TAT-SOD compared with wild SOD, single-function recombinant protein SOD-TAT, and amifostine.

Crystallization and preliminary X-ray diffraction analysis of the SOD-TAT fusion protein.

The superoxide dismutase (SOD) family of proteins are necessary to protect oxygen-utilizing cells from the toxicity of reactive oxygen species. The delivery of SOD into tissues is severely limited by its size and biochemical properties. A cell-membrane-permeable SOD, SOD-TAT, has been demonstrated to have the ability to be directly transduced into mammalian cells.
