What are Some of the Complications of Short Bowel Syndrome?
Discussion
Necrotizing enterocolitis (NEC) is one of the most common gastrointestinal emergencies in neonates. Mortality rates are from 0-45% depending on infant weight and gestation with more premature and smaller infants having greater mortality. NEC usually occurs in premature infants but it also occurs in term infants. The etiology is unknown but is probably multifactorial with ischemia and/or reperfusion playing some role. There are ‘outbreaks’ of NEC but no causative organism has been identified. Regardless of the originating cause, inflammation of the intestine and release of inflammatory mediators causes variou...

Higher selenium and manganese levels during pregnancy may protect babies from future high blood pressure
(Johns Hopkins University Bloomberg School of Public Health) Children who were exposed to higher levels of trace minerals manganese and selenium during their mothers' pregnancy had a lower risk of high blood pressure in childhood, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health.

Clever biomolecular labelling enables identification of immune cells
(University of G ö ttingen) Biomolecules regulate the biological functions inside every living cell. If scientists can understand the molecular mechanisms, then it is possible to detect severe dysfunction. At a molecular level, this can be achieved with fluorescent markers that are incorporated into the respective biomolecules. Researchers at the Universities of G ö ttingen and Edinburgh are now able to show that a complex of manganese makes it possible to conveniently label certain biomolecules. Results were published in Nature Communications. (Source: EurekAlert! - Biology)

Plantwatch: the trees that feed on metal
These plants can clean contaminated soils, could they also offer a greener way of collecting much-needed substances?A magnificent tall tree calledPycnandra acuminata grows on the island of New Caledonia in the South Pacific, and it does something strange – when its bark is cutit bleeds a bright blue-green latex that contains up to 25% nickel, a metal highly poisonous to most plants in more than tiny amounts.An estimated 700 plant species have unusually high levels of metal, mostly nickel but not in all cases. The macadamia tree has leaves and sap rich in manganese, although fortunately not in the nut. If such metal-conta...

Scientists reveal elusive inner workings of antioxidant enzyme with therapeutic potential
(DOE/Oak Ridge National Laboratory) The enzyme manganese superoxide dismutase (MnSOD) plays a critical role in maintaining human health by keeping the amount of harmful reactive oxygen molecules in cells under control. By using neutron scattering at Oak Ridge National Laboratory, researchers have now obtained a complete atomic portrait of the enzyme, revealing key information about its catalytic mechanism. The work could help experts develop MnSOD-based treatments and design therapeutics that mimic its antioxidant behavior. (Source: EurekAlert! - Biology)

New factor in the carbon cycle of the Southern Ocean identified
(Helmholtz Centre for Ocean Research Kiel (GEOMAR)) The Southern Ocean is one of the key regions for understanding the climate system. The photosynthesis-performing plankton there contribute significantly to controlling the CO2 concentration in the atmosphere. But which factors favor or limit plankton growth? Researchers have now published a study showing for the first time that, in addition to the micronutrient iron, manganese can play an important role. Among other things, the results have implications for understanding ice ages in the past. (Source: EurekAlert! - Biology)

A hydrophobic FeMn@Si catalyst increases olefins from syngas by suppressing C1 by-products
In this study, a core-shell FeMn@Si catalyst with excellent hydrophobicity was designed to hinder the formation of CO2 and CH4. The hydrophobic shell protected the iron carbide core from oxidation by water generated during FTS and shortened the retention of water on the catalyst surface, restraining the side reactions related to water. Furthermore, the electron transfer from manganese to iron atoms boosted olefin production and inhibited CH4 formation. The multifunctional catalyst could suppress the total selectivity of CO2 and CH4 to less than 22.5% with an olefin yield of up to 36.6% at a CO conversion of 56.1%. (Source: ScienceNOW)
