Although such deep pockets with more than one direct phosphate to ion chelation site normally include magnesium, as shown in one GAC crystal structure, another GAC crystal structure and solution experiments suggest potassium at this site. Both crystal structures also depict two magnesium ions directly bound to the phosphate groups comprising this controversial pocket. Here, we used classical molecular dynamics simulations as well as umbrella sampling to investigate the possibility of binding of potassium versus magnesium inside the pocket and to better characterize the chelation of one of the binding magnesium ions outside the pocket. The results support the preference of the pocket to accommodate potassium rather than magnesium and suggest that one of the closely binding magnesium ions can only bind at high magnesium concentrations, such as might be present during crystallization.

Primary use is in conjunction with hydrogen-bromine regenerative fuel cells. In addition, alternatives to hydrogen gas compression in general applications will be considered. Fuel cells development and deployment for various stationary and mobile applications is gradually gaining momentum. From vehicles to energy storage and generation on the electrical grid level, fuel cells seem to present a valuable opportunity.

The rationale for trialing magnesium as a neuroprotective agent following cerebral ischemia has been based both on its role in maintaining brain tissue homeostasis and on its known cellular actions that are likely to counteract damaging ischemic processes.

Marine macroalgae benefit people culturally, industrially, nutritionally, and ecologically. DOI: Macroalgae are, loosely speaking, those that can be seen with the naked eye. Most of them are classified as benthic, which is to say that they fasten themselves to the seabed. But there is no need to be so formal in talking about benthic macroalgae. We commonly refer to them all the time by the single term seaweeds , and we make use of them far more often than most people realize.

Scientists have long wondered how Earth’s atmosphere filled with oxygen. UBC geologist Matthijs Smit and research partner Klaus Mezger may have found the answer in continental rocks that are billions of years old. Earth’s early atmosphere and oceans were devoid of free oxygen, even though tiny cyanobacteria were producing the gas as a byproduct of photosynthesis. Free oxygen is oxygen that isn’t combined with other elements such as carbon or nitrogen, and aerobic organisms need it to live. A change occurred about three billion years ago, when small regions containing free oxygen began to appear in the oceans.
Then, about 2. This period, known as the Great Oxidation Event, changed chemical reactions on the surface of the Earth completely. They set out to find a link, looking closely at records detailing the geochemistry of shales and igneous rock types from around the world — more than 48, rocks dating back billions of years. Before oxygenation, continents were composed of rocks rich in magnesium and low in silica — similar to what can be found today in places like Iceland and the Faroe Islands.
But more importantly, those rocks contained a mineral called olivine. When olivine comes into contact with water, it initiates chemical reactions that consume oxygen and lock it up. That is likely what happened to the oxygen produced by cyanobacteria early in Earth’s history.

Manganese is a very hard, brittle, gray-white transition metal that is naturally found in a variety of minerals, but never on its own. Manganese is one of the most common elements in Earth’s crust and is widely distributed across the planet’s surface. Manganese is vital to human and animal life in metabolic functions. Many alloys containing manganese are used in steel production, glass making, and even to make the aluminum in soda cans thinner and stronger.
Manganese has been used since ancient times, science writer John Emsley wrote in an article in Nature Chemistry.

Hemorrhagic shock is a type of hypovolemic shock, where intravascular blood loss and consequent alterations in the cell due to the hypoxia result in tissue and organ dysfunction, leading to death, once a certain threshold level is exceeded. For blood restoration, crystalloid solutions temporarily provide a practical approach, but they cannot replace the lost erythrocyte mass occurred due to bleeding, and they have no therapeutic value.
Excessive use causes several problems, especially coagulopathy and increases the mortality risk. The prompt transfer of patient to an ultimate center for treatment, use of blood and blood products in the treatment, and a swift restoration of hemorrhage source are essential. Tourniquet use in the extremities and balloon occlusion of the aorta can be lifesaving. Hemorrhagic shock develops as a result of intravascular volume loss due to bleeding out of the body or into the anatomical spaces inside, causing insufficient oxygen delivery to the cells.
Hemorrhagic shock is a type of hypovolemic shock. If the bleeding does not stop, inadequate oxygen supply may lead to death. Hemorrhagic shock in trauma patients is a predictor of worse outcomes and contributes to early mortality [ 1 ]. Intracellular synthesis of anaerobic metabolites impairs hemostasis, resulting in cell death, apoptosis, or necroptosis. Shock may develop due to several reasons including trauma, maternal hemorrhage, gastrointestinal hemorrhage, perioperative hemorrhage, or ruptured aneurysms [ 2 ].

Crystalised magnesium. Source: Wikimedia Commons. Magnesium is the eighth most abundant element in the Earth’s crust. The metal can be produced artificially, but is highly reactive. When exposed to the atmosphere it is coated in a thin layer of oxide that partly inhibits reactivity. Magnesium is used in super-strong, lightweight materials and alloys. Magnesium is the lightest of all metals, being about two-thirds lighter than aluminium.
