Centennial to millennial-scale changes in oxygenation and productivity in the Eastern Tropical South Pacific during the last 25,000 years
(Elsevier, 2015)
Oxygen minimum zones (OMZ) have expanded in all tropical oceans during the last 50 years resulting in habitat contraction and considerable changes in marine biogeochemistry. However, for a better understanding of the OMZ ...
Molecular recognition: Evidence of the redox role of ferrocenyl-imine derivatives in the presence of copper (II) ions
(2019)
The design and development of new selective and sensitive chemosensors for metal ions is an area of intense research activity due to their important roles in medicine, living systems, and the environment. In this work, ...
A highly efficient redox chromophore for simultaneous application in a photoelectrochemical dye sensitized solar cell and electrochromic devices
(Royal Soc ChemistryCambridgeInglaterra, 2005)
External copper inhibits the activity of the large-conductance calcium- and voltage-sensitive potassium channel from skeletal muscle
(2003)
We have characterized the effect of external
copper on the gating properties of the large-conductance calcium- and voltage-sensitive potassium channel from skeletal muscle, incorporated into artificial
bilayers. The ...
Multidecadal changes in marine subsurface oxygenation off central Peru during the last ca. 170 years
(Frontiers Media, 2019)
Subsurface water masses with permanent oxygen deficiency (oxygen minimum zones, OMZ) are typically associated with upwelling regions and exhibit a high sensitivity to climate variability. Over the last decade, several ...
Redox dyshomeostasis in the experimental chronic hepatic overloads with iron and copper
(Elsevier Science Inc, 2019-02)
Male rats of 80–90 g were overloaded with either Fe(II) or Cu(II) for 42 days by high concentrations of FeCl2 or CuSO4 in the drinking water. The animals were fed with a commercial rodent diet of 2780 kcal/100 g. Both metal ...
Redox-state sensing by hydrogen bonds in the CuA center of cytochrome c oxidase
(Elsevier Science Inc, 2013-07)
Cytochrome c oxidases (CcO) couple electron transfer to active proton translocation through a gated mechanism that minimizes energy losses by preventing protons from flowing backwards or leaking. Such a complex mechanism ...
