Esterification of Tertiary Amides: Remarkable Additive Effects of Potassium Alkoxides for Generating Hetero Manganese-Potassium Dinuclear Active Species.
Abstract A catalyst system of mononuclear manganese precursor 3 combined with potassium alkoxide served as a superior catalyst compared with our previously reported manganese homodinuclear catalyst 2a for esterification of not only tertiary aryl amides, but also tertiary aliphatic amides. On the basis of stoichiometric reactions of 3 and potassium alkoxide salt, kinetic studies, and density functional theory (DFT) calculations, we clarified a plausible reaction mechanism in which in situ generated manganese-potassium heterodinuclear species cooperatively activate the carbonyl moiety of the amide and the OH moiety ...

Trace Elements' Contamination of Pediatric Parenteral Nutrition Solutions in Canada: A Cause for Concern.
Abstract BACKGROUND: Trace elements' (TEs) contamination of parenteral nutrition (PN) solutions is an ongoing concern. The aims of this study were 1) to measure actual TE concentrations in PN admixtures compared with ordered concentrations and 2) compare TE intake with current recommendations. METHODS: PN admixtures from discarded bags were collected from patients receiving home PN and on inpatient wards. Samples were collected from 72 patients (39 inpatients, 33 receiving home PN). Age, percentage energy intake from PN, and PN orders were collected from patients' charts. PN samples were analyzed for TEs, inc...

Growth of the aquatic macrophyte Ricciocarpos natans (L.) Corda in different temperatures and in distinct concentrations of aluminum and manganese.
o MBD Abstract One of the consequences of global mining is the exposure of metals into the environment, caused by the rupture of tailings dams. Excess of metals, such as aluminum (Al) and manganese (Mn) can cause serious damage to fauna and flora. The presence of these metals, associated with the temperature increase that occurs nowadays can potentially increase biochemical and metabolic rates in plant tissues and may affect growth. Therefore, the objective of this work was to evaluate the toxicity of the metals Al and Mn into the biomass' growth of the macrophyte Ricciocarpos natans, under two temperatures (25 an...

Total reflection X-ray fluorescence spectrometry for trace determination of iron and some additional elements in biological samples.
d K Abstract Trace elements are essential for life and their concentration in cells and tissues must be tightly maintained and controlled to avoid pathological conditions. Established methods to measure the concentration of trace elements in biological matrices often provide only single element information, are time-consuming, and require special sample preparation. Therefore, the development of straightforward and rapid analytical methods for enhanced, multi-trace element determination in biological samples is an important and raising field of trace element analysis. Herein, we report on the development and valid...

Chromium, manganese, nickel, and cobalt mobility and bioavailability from mafic-to-ultramafic mine spoil weathering in western Massachusetts, USA
AbstractFragmented ultramafic bodies in New England were important mineral resources until the early twentieth century, yet few studies have addressed their potential to release trace metals to terrestrial and aquatic environments. Here, we evaluate the release of four trace metals (Cr, Co, Mn, and Ni) from a historic serpentine –talc “soapstone” quarry in Blandford, MA, USA. Soil pits, sediment and rock samples, and stream water samples were collected from upslope undisturbed areas, within the mine spoils and mine face, and downslope of the mine. In order to provide a bottom-up approach for understanding...

Metalation: nature's challenge in bioinorganic chemistry.
Abstract The association of proteins with metals, metalation, is challenging because the tightest binding metals are rarely the correct ones. Inside cells, correct metalation is enabled by controlled bioavailability plus extra mechanisms for tricky combinations such as iron and manganese.

Development of a Novel and Rapid Antibody-Based Diagnostic for Chronic Staphylococcus aureus Infections Based on Biofilm Antigens [Immunoassays]
Prosthetic joint infections are difficult to diagnose and treat due to biofilm formation by the causative pathogens. Pathogen identification relies on microbial culture that requires days to weeks, and in the case of chronic biofilm infections, lacks sensitivity. Diagnosis of infection is often delayed past the point of effective treatment such that only the removal of the implant is curative. Early diagnosis of an infection based on antibody detection might lead to less invasive, early interventions. Our study examined antibody-based assays against the Staphylococcus aureus biofilm-upregulated antigens SAOCOL0486 (a lipop...

Investigation of Effects of Two Chronic Stress Protocols on Depression-Like Behaviors and Brain Mineral Levels in Female Rats: an Evaluation of 7-Day Immobilization Stress.
Abstract We aimed to investigate the effects of two different chronic immobilization stress protocols on depression-related behaviors and brain mineral levels. Adult female Wistar albino rats were divided into 3 groups as follows (n = 10/group): control, immobilization stress-1 (45 min daily for 7 days), and immobilization stress-2 (45 min twice a day for 7 day). Stress-related behavior was evaluated by means of the forced swimming test (FST) and open field test (OFT). Minerals were analyzed using an inductively coupled plasma mass spectrometer. In the FST, swimming and immobility...

Specifically, for human immunodeficiency virus type-1 (HIV-1), divalent cations are required for interactions between viral and host factors that govern HIV-1 replication and pathogenicity. Homeostatic regulation of divalent cations&rsquo; levels and actions appear to change as HIV-1 infection progresses and as changes occur between HIV-1 and the host.

Manganese-modulated cobalt-based layered double hydroxide grown on nickel foam with 1D-2D-3D heterostructure for highly efficient oxygen evolution reaction and urea oxidation reaction.
Abstract Hydrogen production via energy-efficient electrochemical water electrolysis is a green avenue to meet the development of contemporary society. However, oxygen evolution reaction (OER) and urea oxidation reaction (UOR) occurring on the anode are impeded by the sluggish kinetics reaction during the water-splitting process. Consequently, it is promising to develop bifunctional anodic electrocatalyst consisting of non-precious metal. Herein, we report a bifunctional CoMn layered double hydroxides (LDH) grown on nickel foam with a 1D-2D-3D hierarchical structure for efficient OER and UOR performance in alkalin...
