The M-type phospholipase A2 receptor (PLA2R) is a target autoantigen in adult idiopathic membranous nephropathy (MN), but the prevalence of autoantibodies against PLA2R is unknown among Chinese patients with MN. Here, we measured anti-PLA2R antibody in the serum of 60 patients with idiopathic MN, 20 with lupus-associated MN, 16 with hepatitis B (HBV)-associated MN, and 10 with tumor-associated ...

At physiological pH and concentrations of Mn(++) in excess of 5 x 10(-4)M, study of the Mn(++) ion movement into human red cells is complicated by physicochemical alterations of the ion itself. At concentrations below 5 x 10(x4)M, the rate of uptake bears a linear relationship to the Mn(++) concentration. The permeability constant for inward movement of Mn(++) is 2.87 +/- 0.13 (S.E.) x 10(-9) c...

Manganese materials with attractive optical properties have been proposed for applications in such areas as photonics, light-emitting diodes, and bioimaging. In this paper, we have demonstrated multicolor Mn2+ luminescence in the visible region by controlling Ce3+-Mn2+ energy transfer in rare earth nanocrystals [NCs]. CeF3 and CePO4 NCs doped with Mn2+ have been prepared and can be well dispers...

Extensively studied Mn-doped semiconductor nanocrystals have invariably exhibited photoluminescence over a narrow energy window of width ≤150  meV in the orange-red region and a surprisingly large spectral width (≥180  meV), contrary to its presumed atomic-like origin. Carrying out emission measurements on individual single nanocrystals and supported by ab initio calculations, we show that Mn P...

Illumination of chloroplasts in the presence of NH(2)OH (2 mm) leads to the destruction of all system II activities without affecting system I activity. The system II primary charge separation remains intact when incubated with this agent in the dark with release of one of the system II Mn pools and simultaneous destruction of O(2) evolving capacity. The size of the Mn pool associated with the ...

Three experiments wereconducted to evaluate chemical characteristics, intestinal absorption and bioavailability of manganese(Mn)from organic, inorganic and nano sources of Mn. In experiment 1, inorganic sources of Mn including Mn-sulphate and Mn-oxide, organic sources of Mn as Mn-glycinate and Mn-bioplex and FRA® easy dry Mn as a nano source of Mn were subjected to elemental analysis and solubi...

In the present study, micellar-enhanced ultrafiltration (MEUF) was used to remove manganese (Mn) (II) from synthetic wastewater. The effects of different operational conditions on the filtration performance of MEUF or the membrane were studied. It was found that the transmembrane pressure has a major influence on the permeate flux and an insignificant effect on the rejection coefficient. The pe...

Mechanical alloying of binary and ternary elemental powder mixtures with the nominal compositions of Mg2Ni and Mg(2-x)MnxNi (x= 0, 0.05, 0.10 and 0.15 at. %) were carried out in a planetary ball mill for various milling times of 5, 10, 15, 20, 30 and 60 h. X-ray diffraction and field emission scanning and transmission electron microscopy were used for the characterization of the milled products...

OBJECTIVE To determine the relationship between biomarkers of exposure, disease and susceptibility, and early health effects and long-term diseases related to occupational manganese (Mn) exposure. DESIGN Baseline survey of a longitudinal cohort study of workers in a ferromanganese refinery. PARTICIPANTS A total of 1888 individuals (1197 men, 691 women; average seniority 15.34 years) were en...
