Using MnSO4 ̈H2O as manganese source and urea as nitrogen source, Mn/N co-doped TiO2 loaded on wood-based activated carbon fiber (Mn/Ti-N-WACF) was prepared by sol–gel method. Mn/Ti-N-WACF with different Mn doping contents was characterized by scanning electron microscopy, X-ray diffraction (XRD) and X-ray photoelectron spectroscopies (XPS), and ultraviolet-visible spectrophotometer. Results sho...

Purpose: Comparison of transcutaneous immunization of ovalbumin (OA) between twoand three-layered dissolving microneedles (MN) in rats. Methods: We prepared 500 μm long two-layered and three-layered dissolving microneedle (2-MN and 3-MN, respectively) arrays from chondroitin sulfate as the base, and OA as the model antigen. The 2-MN containing OA at the acral portion and 3-MN with OA at the sec...

Manganese (Mn) is the second most prevalent transition metal in the Earth's crust but its availability is often limited due to rapid oxidation and low mobility of the oxidized forms. Acclimation to low Mn availability was studied in Arabidopsis seedlings subjected to Mn deficiency. As reported here, Mn deficiency caused a thorough change in the arrangement and characteristics of the root epider...

Manganese (Mn) is an often overlooked but important nutrient, required in small amounts for multiple essential functions in the body. A recent study on cows fed genetically modified Roundup(®)-Ready feed revealed a severe depletion of serum Mn. Glyphosate, the active ingredient in Roundup(®), has also been shown to severely deplete Mn levels in plants. Here, we investigate the impact of Mn on p...

Manganese peroxidase (MnP) is an extracellular heme enzyme that catalyzes the peroxide-dependent oxidation of Mn(II) to Mn(III). The Mn(III) is released from the enzyme in complex with oxalate. One heme propionate and the side chains of Glu35, Glu39, and Asp179 were identified as Mn(II) ligands in the 2.0 A resolution crystal structure. The new 1.45 A crystal structure of MnP complexed with Mn(...

Manganese (Mn) deficiency is an important plant nutritional disorder in many parts of the world. Barley (Hordeum vulgare) genotypes differ considerably in their ability to grow in soils with low Mn(2+) availability. Differential genotypic Mn efficiency can be attributed to differences in Mn(2+) uptake kinetics in the low nanomolar concentration range. However, the molecular basis for these diff...

BACKGROUND Limited published literature exists on the utility and standardization of anti-phospholipase A2 receptor (anti-PLA2R) immunohistochemistry (IHC) for the diagnosis of primary membranous nephropathy (MN). The study aimed to validate anti-PLA2R IHC for the diagnosis of primary MN and clinicopathological correlations in an Indian cohort. METHODS Subjects included patients with primary ...

We evaluated biochemical endpoints related to oxidative stress in brains of neonatal rats exposed to manganese (Mn). Oral Mn chloride (MnCl2) (0, 25, or 50 mg Mn chloride kg(-1) body weight per day) was given daily to neonatal rats throughout lactation (i.e. from postnatal day (PND) 1 to 21). As previously reported by [J. Appl. Toxicol. 20 (2000) 179], this treatment paradigm results in increas...

A rare-earth free red emitting β-Zn3B2O6:Mn(2+) phosphor was prepared by a solid-state reaction method. The crystal structure, photoluminescent and cathodoluminescent properties of β-Zn3B2O6:Mn(2+) were systematically investigated. The absorption and photoluminescence excitation spectra confirm that β-Zn3B2O6:Mn(2+) matches the UV LED chip. Under UV light and low-voltage electron beam excitatio...
