Copper deficiency is a rare cause of pancytopenia that may be mistaken for myelodysplastic syndrome. Cytoplasmic vacuolization in erythroid and myeloid precursors is found on bone marrow examination. Patients with a history of abdominal surgery who present with anemia and neutropenia with dysplastic changes should have copper levels checked.

Facile phase selective synthesis of copper antimony sulphide (CAS) nanostructures is important because of their tunable photoconductive and electrochemical properties. In this study, off-stoichiometric famatinite phase CAS (CAS) quasi-spherical and quasi-hexagonal colloidal nanostructures (including nanosheets) of sizes, 2.4-18.

The sulfidization-xanthate flotation process has been used commercially with some success in recovering azurite, but it remains unsatisfactory in terms of the environmental impact and flotation index. To remediate these deficiencies, this study evaluated the flotation performance of sodium trithiocarbonate (NaCS) as a green sulfidizing agent for azurite. Flotation test results demonstrated that NaCS has the same efficacy as sodium sulfide but markedly superior activation performance.

Electroactive organisms contribute to metal cycling, pollutant removal, and other redox-driven environmental processes via extracellular electron transfer (EET). Unfortunately, developing genotype-phenotype relationships for electroactive organisms is challenging because EET is necessarily removed from the cell of origin. Microdroplet emulsions, which encapsulate individual cells in aqueous droplets, have been used to study a variety of extracellular phenotypes but have not been applied to investigate EET.

Subacute-to-chronic gait instability has a broad differential diagnosis. The neurological exam can help elucidate the localization and suggest an underlying etiology of the symptomatology, which can lead to a more focused diagnostic approach. Two patients are described - 1 with a month of worsening difficulty with ambulation that evolved to bilateral hand discoordination and another with 18 months of progressive difficulty with ambulation that also then progressed to involve her bilateral hands.

Objectives: Increasing research has shown that heavy metal as a neurotoxicant affects cognitive function across the lifespan. Nutritional status may modify susceptibility to heavy metal exposures, which further impacts cognition.
Methods: We conducted a comprehensive search for cross-sectional studies, longitudinal studies, case-control studies and clinical trials on the interaction between nutrient and heavy metal, as well as mixed heavy metal exposure, in relation to cognition across the lifespan.
