Hypothalamus-pituitary-thyroid axis activity and function of cardiac muscle in energy deficit
Journal Title: Advances in Hygiene and Experimental Medicine - Year 2017, Vol 71, Issue
Abstract
Frequently repeated statement that energy restriction is a factor that improves cardiovascular system function seems to be not fully truth. Low energy intake modifies the hypothalamus-pituitary-thyroid axis activity and thyroid hormone peripheral metabolism. Thyroid hormones, as modulators of the expression and activity of many cardiomyocyte proteins, control heart function. Decreased thyroid hormone levels and their disturbanced conversion and action result in alternation of cardiac remodeling, disorder of calcium homeostasis and diminish myocardial contractility. This review provides a summary of the current state of knowledge about the mechanisms of energy restriction effects on thyroidal axis activity, thyroid hormone peripheral metabolism and action in target tissues, especially in cardiac myocytes. We also showed the existence of energy restriction-thyroid-heart pathway.

Metastatic potential of NET in neoplastic disease
In response to various stimuli, neutrophils and eosinophils can release neutrophil extracellular traps (NET) consisting of proteolytic enzymes, DNA and other components of the cell nucleus. The NETosis process has been c...
Paraneoplastic syndromes and rheumatic diseases
Paraneoplastic syndromes, which are discussed in this paper, are a heterogeneous group of disorders associated with cancer, but not directly caused by the physical effects of the primary tumor or its metastases. May prec...
Increased percentage of CD8+CD28– suppressor lymphocytes in peripheral blood and skin infiltrates correlates with advanced disease in patients with cutaneous T-cell lymphomas
Introduction: T cells with the CD8+CD28– phenotype are CD8+ lymphocytes with regulatory function. Their increased numbers were observed in infections, autoimmune and neoplastic diseases, and in elderly healthy individual...
