Protein inhibitor of activated STAT1 (PIAS1) alleviates cerebral infarction and inflammation after cerebral ischemia in rats.

Background: Ischemic stroke is a severe disorder with high incidence, disability rate and mortality. Multiple pathogenesis mechanisms are involved in ischemic stroke, such as inflammation and neuronal cell apoptosis. Protein inhibitor of activated signal transducer and activators of transcription 1 (PIAS1) plays a crucial role in various biological processes, including inflammation.

Removal of multiple metal ions from wastewater by a multifunctional metal-organic-framework based trap.

The design and preparation of multifunctional adsorbent for practical wastewater treatment is still an enormous challenge. To remove multiple metal ions from wastewater, we developed a broad-spectrum metal ions trap named UIO-67-EDTA by incorporation of ethylenediaminetetraacetic acid into robust UIO-67. The adsorption experiments for 15 kinds of heavy metal ions including hard acid (Mn, Ba, Al, Cr, Fe), borderline acid (Co, Ni, Cu, Zn, Pb, Sn, Bi), soft acid (Ag, Cd, Hg), and two kinds of dissolved minerals (Mg, Ca) show that the trap is very effective both in batch adsorption processes and breakthrough processes.

Effects of high dose copper on plant growth and mineral nutrient (Zn, Fe, Mg, K, Ca) uptake in spinach.

Loessal soil is one of the main cultivated soils in northwest China. Part of its distribution area was irrigated with industrial wastewater in past three decades. This caused heavy metal contamination in the soil.

Electronic and Magnetic Properties of Stone⁻Wales Defected Graphene Decorated with the Half-Metallocene of ( = Fe, Co, Ni): A First Principle Study.

The geometrical, electronic structure, and magnetic properties of the half-metallocene of ( = Fe, Co, Ni) adsorbed on Stone⁻Wales defected graphene (SWG) were studied using the density functional theory (DFT), aiming to tune the band structure of SWG. The introduction of cyclopentadienyl (Cp) and half-metallocene strongly affected the band structure of SWG. The magnetic properties of the complex systems originated from the 3D orbitals of ( = Fe, Co, Ni), the molecular orbital of Cp, and SWG.
