Homeostasis of metals in the progression of Alzheimer’s disease [PDF]
In order to study the involvement of metals in the progression of Alzheimer's disease, serum samples from patients with Alzheimer and mild cognitive impairment were investigated. For this purpose, metal content was analyzed after size-fractionation of species and then, inter-element and inter-fraction ratios were computed.

The roles of organic matter in seawater have often been discussed from the aspect of metal toxicity and bioavailability in seawater. In fact, organic ligands, as part of the organic matter, can work as a trace metal ion buffer system.

Metal ion transporters and homeostasis [PDF]
Transition metals are essential for many metabolic processes and their homeostasis is crucial for life. Aberrations in the cellular metal ion concentrations may lead to cell death and severe diseases. Metal ion transporters play a major role in maintaining the correct concentrations of the various metal ions in the different cellular compartments ...

Autophagy: A role in metal ion homeostasis? [PDF]
Nutrient limitation is one of the most common forms of stress encountered by microorganisms in the environment. Surviving this stress depends upon a number of integrated responses, one of the most important of which is autophagy. When the filamentous fungus Aspergillus fumigatus becomes nutrient deprived it undergoes two important processes: the ...

Metals in Cyanobacteria: Analysis of the Copper, Nickel, Cobalt and Arsenic Homeostasis Mechanisms
Traces of metal are required for fundamental biochemical processes, such as photosynthesis and respiration. Cyanobacteria metal homeostasis acquires an important role because the photosynthetic machinery imposes a high demand for metals, making them a ...

Lysosome-related Organelles as Mediators of Metal Homeostasis [PDF]
Metal ion assimilation is essential for all forms of life. However, organisms must properly control the availability of these nutrients within the cell to avoid inactivating proteins by mismetallation. To safeguard against an imbalance between supply and demand in eukaryotes, intracellular compartments contain metal transporters that load and unload ...
