Introduction: Concentrating of Mn in the human body leads to Manganism, a Parkinson-like disease with pathologic effects especially on brain. Being exposed to the occupations related to metals such as working in the mines, industries and chemical fertilizers in agriculture may cause manganism. Chelating agents have been used successfully in the treatment of severe manganism. This study was cond...
MN-UA1, the distance between the medial end of the median nerve and lateral end of the ulnar artery (MN-UA) at the level of 1 cm proximal to the distal wrist crease (DWC); MN-UA2, MN-UA at the level of 0.5 cm proximal to the DWC; MN-UA3, MN-UA at the level of DWC; MN-UA4, MN-UA at the level of 1 cm distal to the DWC; CSA, cross-sectional area of median nerve; SD, short diameter of median nerve;...
Manganese (Mn) intoxication results in neurological conditions similar, but not identical, to idiopathic Parkinson's disease. While the mechanism(s) by which Mn exposure leads to neurotoxic effects remains unclear, studies by magnetic resonance imaging demonstrate a high Mn accumulation in the hippocampal formation (HPCf) of the brain. Metal quantification using this method is not possible. Usi...
Manganese-oxidizing bacteria in the aquatic environment have been comprehensively investigated. However, little information is available about the distribution and biogeochemical significance of these bacteria in terrestrial soil environments. In this study, stratified soils were initially examined to investigate the community structure and diversity of manganese-oxidizing bacteria. Total 344 c...
A series of new manganese thioarsenates(V) [Mn(en)2Cu(AsVS4)]n (1, en = ethylenediamine), [Mn(dien)2][Mn(dien)(AsVS4)]2 (2, dien = diethylenetriamine), [Mn(teta)(AsVS4)]n (3, teta = triethylenetetramine), and {[Mn(dap)2][Mn(dap)(AsVS4)]2}n (4, dap = 1,2-diaminopropane) have been solvothermally synthesized and structurally characterized. 1 displays a neutral heterometallic [Mn(en)2Cu(AsVS4)]n ch...

Computational intelligence refers to an algorithm inspired by the body structure of natural animals and plants unique landscapes. It can perform simultaneous multithreaded work. In processing process food industry, multiple factors must be considered at same time optimize various parameters simultaneously. Therefore, this research combines computational algorithms with flow conducts on optimiza...
23 Coal mine drainage (CMD) is the single greatest threat to the environment of Appalachia 24 in the United States, releasing large volumes of acid and metal contaminants (e.g., Mn, Fe). 25 Passive limestone-based treatment systems are the most cost-effective method for manganese(II) 26 removal from CMD. The success of passive Mn(II)-removal systems has been variable due to a 27 poor understand...
Fully epitaxial magnetic tunnel junctions (MTJs) with Co-based Heusler alloy Co(2)MnSi electrodes and a MgO tunnel barrier were fabricated with various values of Mn composition α for Co(2)Mn(α)Si in Co(2)Mn(α)Si/MgO/Co(2)Mn(α)Si MTJs. The tunnel magnetoresistance (TMR) ratios at both 4.2 K and room temperature (RT) increased systematically with increasing α in Co(2)Mn(α)Si electrodes from Mn-de...
AIMS/INTRODUCTION To elucidate the clinical significance of median neuropathy at the wrist (MN) in patients with diabetes. MATERIALS AND METHODS In total, 340 patients with diabetes who were hospitalized for glycemic control were enrolled in the present study. The diagnoses of MN and diabetic polyneuropathy (DPN) were based on electrophysiological criteria. A total of 187 patients were divide...
