The dentate gyrus of the hippocampus is a site of adult neurogenesis, and is also known to contain one of the highest concentrations of labile brain zinc (Zn), thought to aid in learning and memory by supporting neurogenesis. At the same time, it is known that unbound Zn, when present at excessive levels, decreases the formation of new neurons. Since mast cells contain Zn transporters capable o...

In the present study, a conversion layer mainly composed by cerium oxide was prepared by means of a novel ultrasound-assisted coating process. The formation of a conversion layer on top of the Mg alloy provides physical barrier properties improving the corrosion protection. In addition, the incorporation of cerium oxide within the coating enables the formation of a protective layer on the pores...

Elucidating the reaction mechanisms and estimating the associated transport and thermodynamic parameters are important for an accurate description of the fate of toxic metal pollutants, such as Zn(II), in soils and aquatic ecosystems rich in iron oxides. Consequently, sorption of Zn(II) ions onto ferrihydrite was investigated with macroscopic and spectroscopic studies as a function of pH (4.0-8...

Coating helps! Employing protective coating on nickel-rich layered oxide cathodes (NRLOs) particles is a crucial necessity, especially when NRLOs are applied for solid-state batteries (SSBs) using sulfidic solid electrolytes (SSEs). Dry-coating promotes cathode particle kinetics by shielding surface of NRLO with nanostructured fumed oxides against side reactions, resulting in enhanced rate capa...

Once penetrated into the lungs of exposed people, asbestos induces an in vivo biomineralisation process that leads to the formation of a ferruginous coating embedding the fibres. The ensemble of the fibre and the coating is referred to as asbestos body and is believed to be responsible for the high toxicological outcome of asbestos. Lung tissue of two individuals subjected to prolonged occupati...

A community-based, randomized, placebo-controlled, double-blind trial was conducted from March 2001 to March 2002 in Kilosa, a rural district of Morogoro Region in Tanzania. One hundred and fifty-eight infants were selected randomly from lists of local Maternal and Child Health Care Centres and received either processed complementary food (PCF) or unprocessed complementary food (UPCF) from age ...

The maintenance of waterways generates large amounts of dredged sediments, which are deposited on adjacent land surfaces. These sediments are often rich in metal contaminants and present a risk to the local environment. Understanding how the metals are immobilized at the molecular level is critical for formulating effective metal containment strategies such as phytoremediation. In the present w...

Wehr, J.D., Kelly, M.G. and Whitton, B.A., 1987. Factors affecting accumulation and loss of zinc by the aquatic moss Rhynchostegium riparioides (Hedw.) C. Jens. Aquat. Bot., 29: 261-274. Reciprocal transplants of the moss Rhynchostegium riparioides (Hedw.) C. Jens. between populations from stre~ma with high (0.27 mg 1 ~) and low (0.05 mg 1~) concentrations of Zn showed that Zn uptake over the f...
