Abstract
Regulated cell death, including pyroptosis, apoptosis, and necroptosis, is vital for the body's defense system. Recent research suggests that these three types of cell death are interconnected, giving rise to a new concept called PANoptosis. PANoptosis has been linked to various diseases, making it crucial to comprehend its mechanism for effective treatments. PANoptosis is controlled by upstream receptors and molecular signals, which form polymeric complexes known as PANoptosomes. Cell death combines necroptosis, apoptosis, and pyroptosis and cannot be fully explained by any of these processes alone. Understanding pyroptosis, apoptosis, and necroptosis is essential for understanding PANoptosis. Physical exercise has been shown to suppress pyroptotic, apoptotic, and necroptotic signaling pathways by reducing inflammatory factors, proapoptotic factors, and necroptotic factors such as caspases and TNF-alpha. This ultimately leads to a decrease in cardiac structural remodeling. The beneficial effects of exercise on cardiovascular health may be attributed to its ability to inhibit these cell death pathways.

Abstract
Interferon Gamma Inducible Protein 16 (IFI16) belongs to the HIN-200 protein family and is pivotal in immunological responses. Serving as a DNA sensor, IFI16 identifies viral and aberrant DNA, triggering immune and inflammatory responses. It is implicated in diverse cellular death mechanisms, such as pyroptosis, apoptosis, and necroptosis. Notably, these processes are integral to the emergent concept of PANoptosis, which encompasses cellular demise and inflammatory pathways. Current research implies a significant regulatory role for IFI16 in PANoptosis, particularly regarding cardiac pathologies. This review delves into the complex interplay between IFI16 and PANoptosis in heart diseases, including atherosclerosis, myocardial infarction, heart failure, and diabetic cardiomyopathy. It synthesizes evidence of IFI16's impact on PANoptosis, with the intention of providing novel insights for therapeutic strategies targeting heart diseases.

Abstract
BACKGROUND AND PURPOSE Atherosclerotic plaque rupture is considered the most important mechanism that underlies the onset of stroke, myocardial infarction, and sudden death. Several evidences demonstrated the pivotal role of inflammatory processes in plaque destabilization. MicroRNAs (miRNAs) are small endogenous RNAs and represent a new important class of gene regulators. Nevertheless, no data exist about the expression profile of miRNAs in atherosclerotic plaques. Thus, the aim of this study was to investigate the expression level of miRNAs in human plaques and to correlate it with clinical features of plaque destabilization. METHODS Two separate groups of plaques were collected from patients who underwent carotid endarterectomy in Chieti (n=15) and Ancona (n=38) Hospitals. All the plaques were subdivided in symptomatic (n=22) and asymptomatic (n=31) according to the presence/absence of stroke. RESULTS First, on the plaques collected at Chieti Hospital, we performed large-scale analysis of miRNA expression. Between the 41 miRNAs examined, we discovered profound differences in the expression of 5 miRNAs (miRNA-100, miRNA-127, miRNA-145, miRNA-133a, and miRNA-133b) in symptomatic versus asymptomatic plaques. Remarkably, when we repeated the analysis on the Ancona plaque subset, all these 5 miRNAs confirmed to be significantly more expressed in the symptomatic plaques. Finally, in vitro experiments on endothelial cells transfected with miRNA-145 and miRNA-133a confirmed the importance of these miRNAs in the modulation of stroke-related proteins. CONCLUSIONS These results are the first to report alterations in the expression of specific miRNAs in human atherosclerotic plaques and suggest that miRNAs may have an important role in regulating the evolution of atherosclerotic plaque toward instability and rupture. Furthermore, by identifying the specific miRNA signature for stroke now, we are able to use computer algorithms to identify previously unrecognized molecular targets.

Abstract
Preclinical cardiovascular research using noninvasive radionuclide and hybrid imaging systems has been extensively developed in recent years. Single photon emission computed tomography (SPECT) is based on the molecular tracer principle and is an established tool in noninvasive imaging. SPECT uses gamma cameras and collimators to form projection data that are used to estimate (dynamic) 3-D tracer distributions in vivo. Recent developments in multipinhole collimation and advanced image reconstruction have led to sub-millimetre and sub-half-millimetre resolution SPECT in rats and mice, respectively. In this article we review applications of microSPECT in cardiovascular research in which information about the function and pathology of the myocardium, vessels and neurons is obtained. We give examples on how diagnostic tracers, new therapeutic interventions, pre- and postcardiovascular event prognosis, and functional and pathophysiological heart conditions can be explored by microSPECT, using small-animal models of cardiovascular disease.

Abstract
Current imaging techniques focus on evaluating the anatomical structure of blood vessel wall and atherosclerotic plaque. These techniques fail to evaluate the biological processes which take place in the vessel wall and inside the plaque. Novel imaging techniques like optical imaging can evaluate the biological and cellular processes inside the plaque and provide information which can be vital for better patient risk stratification. This review highlights the various optical imaging techniques and their application in assessing biological processes in atherosclerosis.

Abstract
Steroidogenic acute regulatory protein (StAR) plays an important role in the maintenance of intracellular lipid homeostasis. Macrophages are the key cellular player in the pathophysiology of atherosclerosis. Imbalance of macrophage lipid homeostasis causes cellular apoptosis, which is the key process in the initiation of atherosclerosis. The present study has investigated the effects of StAR in the apoptotic process of human THP-1 derived macrophages induced by serum withdrawal or Ox-LDL. Overexpression of StAR significantly decreased the number of apoptotic macrophages by decreasing the expression of pro-apoptotic genes Caspase-3 and Bax mRNA and protein levels, as well as through increasing expression of anti-apoptotic gene Bcl-2 mRNA and protein levels in the absence and presence of Ox-LDL. The results indicate that StAR plays an important role in macrophage and foam cell apoptotic processing, which may provide a potential method for preventing atherosclerosis.

Abstract
Pathophysiological processes in the vascular system are the major cause of mortality and disease. Atherosclerosis, an inflammatory process in arterial walls, can lead to formation of plaques, whose rupture can lead to thrombus formation, obstruction of vessels (thrombosis), reduction of the blood flow (ischemia), cell death in the tissue fed by the occluded vessel, and depending on the affected vessel, to myocardial infarction or stroke. Imaging techniques enabling visualization of the biological processes involved in this scenario are therefore highly desirable. In recent years, a number of reporter agents and reporter systems have been developed to visualize these processes using different imaging modalities including nuclear imaging techniques, such as positron emission tomography or single photon emission computed tomography, magnetic resonance imaging, and ultrasound. This article comprises a brief overview of optical imaging techniques, such as fluorescence imaging and bioluminescence imaging for the visualization of vascular pathophysiology.

Abstract
Renal cell apoptosis is important in both physiological conditions such as normal renal development and pathological processes affecting the glomerular, vascular or tubulointerstitial compartments. Apoptosis may result in the detrimental loss of cells following many renal diseases or damaging changes, with significant loss of function. In contrast, apoptosis may control and limit inflammatory processes in both the acute and chronic phases of renal disease. Investigators interested in the presence of apoptotic cells in different forms of renal disease and development need methods to accurately determine the level of apoptosis within the kidney. Apoptosis is a gene-driven mode of cell death that may be identified by distinct morphological features, endonuclease-initiated DNA degradation, and by the involvement of specific apoptosis-regulating proteins. Many research papers that analyse the presence of apoptosis use the in situ terminal deoxyribonucleotidyl transferase-mediated deoxyuridine triphosphate nick end labelling (TUNEL) assay that detects DNA strand breaks in situ in tissue sections. Localization of activated caspase-3 is now seen as an alternative to TUNEL. This review will discuss some methods of identifying apoptosis in the kidney, using both morphological and biochemical or molecular characteristics, and also discuss some of the pitfalls of entire reliance on biochemical means of apoptotic cell identification without some morphological checks and balances. Although there are some caveats to the methods for identifying apoptotic cells in renal disease, those investigators who take the time to undertake such analysis often gain insightful data that provide explanations for the disease or condition being studied.
