*  Functional manganese requirement and its use as a critical value for diagnosis of manganese deficiency in subterranean clover ...
The effects of manganese supply on plant growth and on photosynthesis and manganese concentrations in young leaves were examined in Seaton Park subterranean clover in three glasshouse water culture experiments.Plants werc grown initially with a copious supply of manganese, and transferred to solutions either with or without manganese. Sequential harvests were taken to determine the effects of developing manganese deficiency on dry matter (DM) yield of whole plants and selected characteristics [manganese, chlorophyll and photosynthetic oxygen evolution (POE)] of youngest open leaf blades (YOL). In addition, the deffect of leaf age and iron supply on POE werc examined.Manganese concentrations and POE in YOL declined markedly and rapidly in plants transferred to solutions without manganese, while chlorophyll concentrations of YOL and plant DM yield responded more weakly and more slowly. As a result, a level of manganese deficiency which depressed POE in young leaves by more than 50 per cent had no ...
*  Manganese deficiency (medicine) - Wikipedia
Manganese is a component of some enzymes and stimulates the development and activity of other enzymes. Manganese superoxide dismutase (MnSOD) is the principal antioxidant in mitochondria. Several enzymes activated by manganese contribute to the metabolism of carbohydrates, amino acids, and cholesterol.[1]. A deficiency of manganese causes skeletal deformation in animals and inhibits the production of collagen in wound healing.[2]. Manganese is found in leafy green vegetables, fruits, nuts, cinnamon and whole grains. The nutritious kernel, called wheat germ, which contains the most minerals and vitamins of the grain, has been removed from most processed grains (such as white bread). The wheat germ is often sold as livestock feed. Many common vitamin and mineral supplement products fail to include manganese in their compositions. Relatively high dietary intake of other minerals such as iron, magnesium, and calcium may inhibit the proper intake of manganese.[3]. ...

"Children may be particularly susceptible to the neurotoxic effects of ambient Mn exposure, as their brains are undergoing a dynamic process of growth and development," Haynes added.. The results appear online in the journal NeuroToxicology. (ANI). ...
*  The Healing Properties of Tears: 7 Good Reasons to Cry Your Eyes Out - Beyond Blue
3. Tears remove toxins.. Biochemist William Frey, who has been researching tears for as long as I've been searching for sanity, found in one study that emotional tears-those formed in distress or grief-contained more toxic byproducts than tears of irritation (think onion peeling). Are tears toxic then? No! They actually remove toxins from our body that build up courtesy of stress. They are like a natural therapy or massage session, but they cost a lot less!. 4. Crying can elevate mood.. Do you know what your manganese level is? No, neither do I. But chances are that you will feel better if it's lower because overexposure to manganese can cause bad stuff: anxiety, nervousness, irritability, fatigue, aggression, emotional disturbance and the rest of the feelings that live inside my happy head rent-free. The act of crying can lower a person's manganese level. And just like with the toxins I mentioned in my last point, emotional tears contain 24 percent higher albumin protein ...

Analysis of Measured Manganese Concentrations:. 1. Calculate the average: We calculated the average of the manganese measurements (shown by the black diamond in the graph below). We compared this average to the long-term comparison level (thick line on the graph below). The long-term comparison level represents the level of manganese in the air that is below levels associated with health concerns, even if someone breathed air containing manganese at that level all day, every day over their lifetime. Result: The average manganese level for the samples collected was slightly above the long-term comparison level. There is a potential for levels of health concern for long-term continuous exposure, particularly in areas closer to sources where concentrations are higher. ...
*  NewsRoomAmerica.com - Manganese in underground drinking water is cause for concern
Newsroom America) -- Underground drinking water sources in parts of the U.S. and three Asian countries may not be as safe as previously thought due to high levels of manganese, especially at shallow depths, according to a study led by a researcher at the University of California, Riverside. Manganese, a metal that is required by the body in tiny amounts, can be toxic at elevated levels, particularly in children.. Samantha Ying, an assistant professor of environmental sciences in UCR's College of Natural and Agricultural Sciences, led the study, which was published recently in Environmental Science & Technology. The paper describes manganese levels that exceed World Health Organization (WHO) guidelines in groundwater wells in Bangladesh, Cambodia, China, and the Glacial Aquifer, which spans 26 states in the northern U.S. and provides drinking water to more than 41 million Americans. Of the four regions, the Glacial Aquifer had the fewest contaminated wells.. While groundwater can be contaminated ...
*  Is Manganese a Risk Factor for PD? | ALZFORUM
No one knows exactly what causes sporadic Parkinson's disease, but scientists know that both genetic and environmental risk factors contribute. One suspected environmental culprit is manganese, a metal often alloyed with steel to increase its hardness. High levels of manganese are known to be neurotoxic; data on the effects of low levels of environmental manganese exposure are limited, but suggest a link to parkinsonism or PD. A paper in the April 12 Neurology provides compelling new evidence that chronic exposure to manganese correlates with damage to the brain's dopaminergic system. Researchers led by Brad Racette at Washington University, St. Louis, Missouri, found that relatively young, healthy welders, whose work often subjects them to manganese-laden fumes, have abnormalities in dopamine uptake in the caudate nucleus, one of the regions of the brain affected in PD patients. They also had very subtle motor deficits. The long-term medical significance of this finding is unclear, but the data ...

*  Oxygen Evolving Reactions by Synthetic Manganese Complexes
The development of efficient catalyst for water oxidation is of paramount importance to artificial photosynthesis, but before this can be achieved a deeper understanding of this reaction is essential. In nature this reaction occurs in a tetranuclear Mn-cluster which serves as the work-horse of oxygenic photosynthesis. This thesis summarises my efforts at developing molecular systems capable of mimicking this complex employing a biomimetic approach.. Three different approaches towards this goal are described here-in. The first section describes a screening study, in which a number of manganese complexes were tested to see whether or not they were capable of catalysing the formation of dioxygen when treated with different oxidants (Papers I). For those reactions in which dioxygen formation was observed the reactions were repeated in labelled water and the incorporation of labelled O-atoms was studied by mass spectrometry. This allowed us to determine to what extent water was the source of the ...
*  Environmental Health Perspectives - Associations of Early Childhood Manganese and Lead Coexposure with Neurodevelopment
This study suggests that joint exposure to manganese and lead is associated with greater deficits in both mental and psychomotor development than expected based on effects of exposure to either metal alone. Interestingly, this interaction was observed for 12-month but not for 24-month blood metal concentrations. A possible interpretation of the specificity of the interaction of 12-month blood manganese-lead levels is that this is a sensitive developmental window specific to this interaction. From repeated measures models, for a one-unit increase in lead at 12 months, MDI scores were 2.16 points lower among children with high manganese (-0.89 + -0.07 + -1.27 = -2.23), compared with children with midrange manganese [-0.07 (95% CI: -0.39, 0.25)]. PDI scores for a one-unit increase in lead at 12 months were 0.97 points lower among children with high manganese (-0.05 + -0.27 + -0.92 = -1.24), compared with children with midrange manganese [-0.27 (95% CI: -0.56, 0.02)]. Although these differences ...

The formation and maintenance of deep-sea ferromanganese/polymetallic nodules still remains a mystery 140 years after their discovery. The wealth of rare metals concentrated in these nodules has spurred global interest in exploring the mining potential of these resources. The prevailing theory of abiotic formation has been called into question and the role of microbial metabolisms in nodule development is now an area of active research. To understand the community structure of microbes associated with nodules and their surrounding sediment, we performed targeted sequencing of the V4 hypervariable region of the 16S rRNA gene from three nodules collected from the central South Pacific. Results have shown that the microbial communities of the nodules are significantly distinct from the communities in the surrounding sediments, and that the interiors of the nodules harbor communities different from the exterior. This suggests not only differences in potential metabolisms between the nodule and ...
*  Molecular Vision: Light-dependant intraretinal ion regulation by melanopsin in young awake and free moving mice evaluated with...
In this study, intraretinal uptake of manganese was greatest in light-adapted WT P7 mice compared to dark-adapted animals. This light-dark difference in uptake was absent in the melanopsin KO mice. The different control and KO strains used are not considered a confounding factor since a similar light-induced increase in retinal manganese uptake, relative to that in the dark, was also noted in preliminary control P7 Sprague Dawley rat studies (data not shown). The data in Figure 1 and Figure 2 are consistent with melanopsin-mediated effects extending at least partly into the presumptive inner nuclear layer [15]. Together, our data demonstrate for the first time the feasibility of using MEMRI to measure melanopsin-mediated light responses in young mouse retinas in vivo. More work is now needed to analytically evaluate how, for example, the extent of retinal manganese uptake in young rodents is related to circadian rhythm, and how calcium channel activity in other retinal layers is being regulated ...
