“…In the study assessing Cr and Se relationships in chicken brains, it was found that the group exposed to selenium and chromium had a lower concentration of chromium in tissues than the group exposed only to chromium. A clear negative correlation was observed in the pair of elements Cr and Se [19]. This does not correspond with the results obtained in this study.…”

Trace element distribution varies in different locations of the human brain. Several elements were found to cause various negative effects, such as neurodegeneration. In this paper, we analyzed the interactions between seven trace elements: zinc (Zn), selenium (Se), manganese (Mg), iron (Fe), copper (Cu), chromium (Cr) and cobalt (Co) in individuals with alcohol use disorder (AUD) and individuals without (control group). Brain tissue samples from 31 individuals with AUD and 31 control subjects were harvested. Inductively coupled plasma optical emission spectrometry was used for trace element determination. In the control group, there were several positive correlations between Cr, Cu, Fe and Mn. In the AUD group, positive correlations between Co and Cr, Cu, Fe, Mn, Zn were found. The majority of correlations between Zn and other elements are positive. In the studied group, Mn had strong positive correlations with Co, Cr, Cu and Fe. The strongest positive correlation found between average element concentration was between Cu and Cr. The knowledge of kinetics and metabolism of trace elements as well as the impact of alcohol on these processes is essential for understanding the pathological processes and functioning of human brain tissue.

“…A recent study revealed Se-Cr (VI) interaction and other trace elements accumulation in chicken serum and brain. The results demonstrated that Se supplementation decreased accumulation of Cr both in chicken brain and serum and this interaction regulated the correlation and contents of Ca, Cu, Mn, Fe, Zn, and Mg in these tissues [ 145 ]. Another study investigated the effects of Se on the toxicity of Pb and the expressions of selenoproteins mRNA in chicken cartilage tissue.…”

Selenium-Dependent Antioxidant Enzymes: Actions and Properties of Selenoproteins

Unlike other essential trace elements that interact with proteins in the form of cofactors, selenium (Se) becomes co-translationally incorporated into the polypeptide chain as part of 21st naturally occurring amino acid, selenocysteine (Sec), encoded by the UGA codon. Any protein that includes Sec in its polypeptide chain is defined as selenoprotein. Members of the selenoproteins family exert various functions and their synthesis depends on specific cofactors and on dietary Se. The Se intake in productive animals such as chickens affect nutrient utilization, production performances, antioxidative status and responses of the immune system. Although several functions of selenoproteins are unknown, many disorders are related to alterations in selenoprotein expression or activity. Selenium insufficiency and polymorphisms or mutations in selenoproteins’ genes and synthesis cofactors are involved in the pathophysiology of many diseases, including cardiovascular disorders, immune dysfunctions, cancer, muscle and bone disorders, endocrine functions and neurological disorders. Finally, heavy metal poisoning decreases mRNA levels of selenoproteins and increases mRNA levels of inflammatory factors, underlying the antagonistic effect of Se. This review is an update on Se dependent antioxidant enzymes, presenting the current state of the art and is focusing on results obtained mainly in chicken.

“…3). This chemical interaction of Se and Te is not surprising in rats since it has been shown that Se also interacts with mercury and chromium in chickens in other experimental setups [26,27]. Thus, the biology of Se and Te must be understood not only in terms of individual actions of the trace elements in the brain but also in terms of the interactional nature of metalloids in the physiological mechanisms of the brain.…”

Functional laterality is known as an intrinsic property of the brain. Since several studies have shown the presence of laterality in many species other than humans, it has been suggested that this is an adaptive mechanism to aid survival. Previous studies have shown that lateralized behavior observed during exposure to different environmental stimuli is not constant in normal animals, depending on the geometrical form of the exploratory field. In these exploratory fields, animals showed right- or left-biased exploratory behavior, according to the nature of the geometrical properties of the environment. Previously, it was found that tellurium (Te) was able to block spontaneous left-biased exploration in one defined geometrical environment. In the present work, the influence of Te and selenium (Se) in animals exposed to novel geometrically different environments were studied. Three geometrically different testing fields (square, rectangle, and T-shaped) were presented to Se- and Te-treated groups of rats. The results show that in the square field, only the Se treatment was able to block spontaneous right-biased exploratory responses; in the rectangular field, both Se and Te treatments blocked right-biased exploratory responses, and in the T-shaped field, only Te was able to block spontaneous left-biased exploratory responses. Data suggest that trace elements modify lateralized behavioral responses independently of the form of the novel exploratory field, suggesting the presence of a specific action in the brain.
