Trace elements and apoptosis - PubMed
DOI: 10.1016/S0946-672X (98)80028-X Abstract It is known that apoptosis is considered to be responsible for selective deletion of cells during embryogenesis, the homeostasis of cell populations in continuously renewing tissues (i.e., serving as a counterbalance to mitosis), and tissue involution in response to chemical or physical stimuli.

Trace Element - an overview | ScienceDirect Topics
J.W. Spears, T.E. Engle, in Reference Module in Food Science, 2016 Abstract. Trace minerals are required for a number of biological processes in the body. At least eight trace minerals (cobalt, copper, iodine, iron, manganese, molybdenum, selenium, and zinc) are essential for cattle and a deficiency of any of these results in abnormalities such as reduced growth or milk …
Fluids and trace element transport in subduction zones
Abstract. Melt inclusion data from primitive arc basalts from Mexico and Kamchatka show clear positive correlations of "fluid mobile element"/H 2 O ratios with the Cl/H 2 O ratio, suggesting that the trace element content of subduction zone fluids is strongly enhanced by complexing with chloride. This effect is observed for large-ion ...

Trace Elements in River Waters - NASA/ADS
Abstract. Trace elements are characterized by concentrations lower than 1 mg L-1 in natural waters. This means that trace elements are not considered when "total dissolved solids" are calculated in rivers, lakes, or groundwaters, because their combined mass is not significant compared to the sum of Na+, K+, Ca2+, Mg2+, H4SiO4, HCO3-, CO32-, SO42-, Cl-, and NO3-.
