Diabetes mellitus and alterations in thyroid hormone (TH) signaling are closely linked. Though the role of TH signaling in cell differentiation and growth is well known, it remains unclear whether its alterations contribute to the pathobiology of diabetic cells. Here, we aim to investigate whether the administration of exogenous T3 can counteract the cellular remodeling that occurs in diabetic cardiomyocytes, podocytes, and pancreatic beta cells.

Heart failure affects more than 64 million people worldwide, having a serious impact on their survival and quality of life. Exploring its pathophysiology and molecular bases is an urgent need in order to develop new therapeutic approaches. Thyroid hormone signaling, evolutionarily conserved, controls fundamental biological processes and has a crucial role in development and metabolism.

Thyroid hormone (TH) signalling is a universally conserved pathway with pleiotropic actions that is able to control the development, metabolism, and homeostasis of organisms. Using evidence from paleoecology/palaeoanthropology and data from the physiology of modern humans, we try to assess the natural history of TH signalling and its role in human evolution. Our net thesis is that TH signalling has likely played a critical role in human evolution by facilitating the adaptive responses of early hominids to unprecedently challenging and continuously changing environments.

Background Rheumatoid Arthritis (RA) patients show a higher risk of heart failure. The present study investigated possible causes of cardiac dysfunction related to thyroid hormone (TH) signaling in a RA mouse model. Methods A TNF-driven mouse model of RA[TghuTNF (Tg197)] was used.

Purpose Of The Review: In this study, we will analyse how diabetes induces the reactivation of organs' developmental programmes and growth, discuss how thyroid hormone (TH) signalling orchestrates these processes, and suggest novel strategies for exploiting TH-mediated reparative and regenerative properties.

Recent Findings: Diabetes is a global pandemic that poses an enormous threat to human health. The kidney and the heart are among the organs that are the most severely damaged by diabetes over time.

Background: Cardiovascular disease is the leading cause of mortality in renal transplant recipients (RT). Coronary artery disease (CAD) in such patients is poorly studied.

Methods: During 2012-2017, 50 patients with a renal graft (functioning for a minimum of 6 months) were subjected to coronary angiography in our institution.

Background: Acute congestive heart failure (ACHF) is a state of severe, secondary hyperaldosteronism. Relief of congestion has prognostic implications. Our aim was to assess associations between high-dose spironolactone and (1) decongestion and (2) safety in patients with ACHF.

Background/objectives: Left ventricular restraint attenuates post-infarction remodeling, but may be associated with unfavorable long-term histological response. We hypothesized that beneficial effects can be obtained with short-term restraint during the early post-infarction period; for this purpose, we evaluated a biodegradable scaffold in the in vivo rat model and compared it with epicardial hydrogel application.

Methods: A total of 230 Wistar rats (358 ± 7 g) were studied.
