The effects of manganese and copper in vitro and in vivo on peroxidase catalytic cycles
(Elsevier Gmbh, Munich, 2010)
Here we present the results of in vitro and in vivo studies of the influence of Mn2+ and Cu2+ on the peroxidative and oxidative catalytic functions of class III peroxidase. Complex peroxidase catalysis by intermediates ...
Optimization of process of the honeycomb-like structure formation by the regime of reversing current (RC) in the second range
(Springer, New York, 2020)
Formation of the honeycomb-like electrodes of copper by the regime of reversing current (RC) in the second range has been investigated. Morphological and structural characteristics of this electrode type obtained by various ...
Metals and electrolytes in sclerotic hippocampi in patients with drug-resistant mesial temporal lobe epilepsy
(Wiley-Blackwell, Hoboken, 2014)
An altered metal and electrolyte profile has been implicated in the pathologic mechanisms of chronic epilepsy; however, no study has comprehensively measured hippocampal concentrations of these elements in patients with ...
The conformation of biliverdin in dimethyl sulfoxide: implications for the coordination with copper
(Springer/Plenum Publishers, New York, 2019)
Biliverdin (BV) structure was analyzed by using NMR techniques and unrestricted density function theory simulations to explain the incapacity of BV to build coordination complex(es) with Cu2+ in dimethyl sulfoxide, which ...
Physiological basis of differential zinc and copper tolerance of Verbascum populations from metal-contaminated and uncontaminated areas
(Springer Heidelberg, Heidelberg, 2016)
Metal contamination represents a strong selective pressure favoring tolerant genotypes and leading to differentiation between plant populations. We investigated the adaptive capacity of early-colonizer species of Verbascum ...
Sodium sulphide relaxation of rat uterus is related to calcium signaling
(Academic Press Inc Elsevier Science, San Diego, 2014)
H2S was shown as an uterine relaxant. However, the signaling pathways, including ion channels regulated by H2S mediating relaxation in uterus are still unknown. The effects on contractility in response to sodium sulphide ...
Phosphorus deficiency is the major limiting factor for wheat on alluvium polluted by the copper mine pyrite tailings: a black box approach
(Springer, Dordrecht, 2011)
Failures of tailings dams have degraded large areas of agricultural alluvial soils worldwide, and concomitant soil pollution studies are abundant. Yet, the data on the actual effects of thereby imposed stresses on major ...
Coordination and redox interactions of beta-lactam antibiotics with Cu2+ in physiological settings and the impact on antibacterial activity
(Elsevier Science Inc, New York, 2018)
An increase in the copper pool in body fluids has been related to a number of pathological conditions, including infections. Copper ions may affect antibiotics via the formation of coordination bonds and/or redox reactions. ...
The effects of ionizing radiation on the structure and antioxidative and metal-binding capacity of the cell wall of microalga Chlorella sorokiniana
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The impact of ionizing radiation on microorganisms such as microalgae is a topic of increasing importance for understanding the dynamics of aquatic ecosystems in response to environmental radiation, and for the development ...
Estimation of carbon dots amelioration of copper toxicity in maize studied by synchrotron radiation-FTIR
(Elsevier, Amsterdam, 2021)
Carbon dots are biocompatible and non-toxic nanoparticles with chemical affinity to some heavy metals. Human activities increase soil pollution with copper. Cu is an essential microelement in plants, but excess can induce ...
