The role of copper element has been an increasingly relevant topic in recent years in the fields of human and animal health, for both the study of new drugs and innovative food and feed supplements. This metal plays an important role in the central nervous system, where it is associated with glutamatergic signaling, and it is widely involved in inflammatory processes. Thus, diseases involving copper(Ⅱ) dyshomeostasis often have neurological symptoms, as exemplified by Alzheimer's and other diseases(such as Parkinson's and Wilson's diseases). Moreover, imbalanced copper ion concentrations have also been associated with diabetes and certain types of cancer, including glioma. In this paper, we propose a comprehensive overview of recent results that show the importance of these metal ions in several pathologies, mainly Alzheimer's disease, through the lens of the development and use of copper chelators as research compounds and potential therapeutics if included in multi-target hybrid drugs. Seeing how copper homeostasis is important for the well-being of animals as well as humans, we shortly describe the state of the art regarding the effects of copper and its chelators in agriculture, livestock rearing, and aquaculture, as ingredients for the formulation of feed supplements as well as to prevent the effects of pollution on animal productions.

Quantum dispersions of various sets of dynamical variables of an open Bose-Hubbard system in a classical limit are studied. To this end, an open system is described in terms of stochastic evolution of its quantum pure states. It is shown that the class of variables that display classical behaviour crucially depends on the type of noise. This is relevant in the mean-field approximation of open Bose-Hubbard dynamics.

AIM: To assess whether depression and anxiety are more expressed in patients with the first episode of inflammatory bowel disease (IBD) than in individuals with newly discovered cancer of the colon (CCa). METHODS: A total of 32 patients with IBD including 13 males and 19 females, aged 27 to 74, and 30 patients with CCa including 20 males and 10 females, aged 39-78, underwent a structured interview, which comprised Hamilton’s Depression rating Inventory, Hamilton’s Anxiety rating Inventory and Paykel’s Stressful Events rating Scale. rESULTS: Patients of the IBD group expressed both depression and anxiety. Depressive mood, sense of guilt, psychomotor retardation and somatic anxiety were also more pronounced in IBD patients. The discriminant function analysis revealed the total depressive score was of high importance for the classification of a newly diagnosed patient into one of the groups. CONCLUSION: Newly diagnosed patients with IBD have higher levels of depression and anxiety. Moreover, a psychiatrist in the treatment team is advisable from the beginning.

Properties of an operator representing the dynamical time in the extended parameterization invariant formulation of quantum mechanics are studied. It is shown that this time operator is given by a positive operator measure analogously to the quantities that are known to represent various measurable time operators. The relation between the dynamical time of the extended formulation and the best known example of the system time operator, i.e., for the free one- dimensional particle, is obtained.
