Use of Indocyanine Green (ICG) to Assess Myocardial Perfusion and Territorial Distribution of Vein Grafts Implanted on Coronary Arteries in an Porcine Model. A Potential Adjunct to Assist Revascularization Strategies and Training in Coronary Artery Bypass Grafting.

Background: The fluorescent dye indocyanine green (ICG) has been used to identify anatomical structures intraoperatively in coronary artery bypass grafting (CABG). This study aimed to evaluate the feasibility of using ICG to assess graft patency and territorial distribution of myocardial reperfusion during CABG.

Methods: Porcine arrested hearts (n = 18) were used to evaluate territorial distribution of native coronary arteries and of a coronary bypass constructed with porcine saphenous vein graft (SVG) using ICG.

Coronary Microvascular Dysfunction: Insights on Prognosis and Future Perspectives.

Coronary microvascular dysfunction (CMD) comprises a wide spectrum of structural and/or functional abnormalities of coronary microcirculation that can lead to myocardial ischemia. Emerging evidence has indicated that CMD is a relevant cause of morbidity and mortality and is associated with a high risk of major adverse cardiovascular events (MACEs) and heart failure with preserved ejection fraction as well as poor quality of life. This review aims to elucidate briefly the pathogenesis and diagnostic modalities of CMD and to shed light on contemporary evidence on the prognostic impact of CMD.

Transcatheter Tricuspid Valve Replacement: Current Options and Future Perspectives.

Tricuspid regurgitation (TR) is a potentially lethal condition and represents a significant clinical challenge both for clinical and interventional cardiologists. Traditionally managed medically and surgically, transcatheter therapies are now an emerging option, especially in patients with prohibitive surgical risk due to age or comorbidities. Transcatheter tricuspid valve replacement (TTVR) is emerging as a potential solution for patients suffering from TR with positive clinical data supporting its use in a wide range of anatomies and clinical settings.

Cardiopulmonary Exercise Testing: Deciphering Cardiovascular Complications in Systemic Sclerosis.

Cardiac manifestations in systemic sclerosis (SSc) are variable and are associated with a poor prognosis, frequently resulting in impaired right ventricular function and heart failure. A high proportion of patients with SSc experience pulmonary arterial hypertension (PAH), interstitial lung disease, or myocardial involvement, all of which can lead to exercise intolerance. In this context, cardiopulmonary exercise testing (CPET) is a useful tool for diagnosing exercise intolerance, elucidating its pathophysiology, and assessing its prognosis.

Melatonin regulation and the function of the periodontal ligament: Future perspective and challenges.

The present article reviews the emerging role of melatonin (MT) and the Hippo-Yes-associated protein signaling pathway in periodontal regeneration, highlighting their potential to delay the aging process of periodontal ligament stem cells (PDLSCs). Oxidative stress and cellular senescence are major obstacles in regenerative therapies, especially in an aging population. MT, a potent antioxidant, restores the morphology, proliferation, and osteogenic differentiation potential of PDLSCs under oxidative stress conditions.

At the nucleus of cancer: how the nuclear envelope controls tumor progression.

Historically considered downstream effects of tumorigenesis-arising from changes in DNA content or chromatin organization-nuclear alterations have long been seen as mere prognostic markers within a genome-centric model of cancer. However, recent findings have placed the nuclear envelope (NE) at the forefront of tumor progression, highlighting its active role in mediating cellular responses to mechanical forces. Despite significant progress, the precise interplay between NE components and cancer progression remains under debate.

Randomized clinical trial (RCT): An overview.

•Randomized Clinical Trials (RCTs) are the gold standard for human experimental studies.•RCTs demand equipoise and freedom from treatment preference among investigators.•Neurologic RCTs are costly, time-intensive, and have high participant exclusion rates.

Left Ventricular Non-Compaction, Atrial Fibrillation and Mutation in a Young Athlete.

Left ventricular non-compaction (LVNC) is a rare primary cardiomyopathy with genetic etiology, resulting from an abnormality of myocardial development during embryogenesis. It carries an elevated risk of left ventricular dysfunction, thromboembolic events and malignant arrhythmias. We report the case of LVNC associated with paroxysmal atrial fibrillation and ankyrin 2 () mutation at the genetic test.

Musicians and researchers: two creative professions striving to improve heart health through music.

Musicians and researchers are creative professions that share many similarities. They both aim to bring joy and progress to humanity. In recent decades, it has been shown that music has the ability to alleviate pain, improve heart function, reduce anxiety, and stimulate the release of endogenous opioids in the brain.

Melanoma extracellular vesicles membrane coated nanoparticles as targeted delivery carriers for tumor and lungs.

Targeting is the most challenging problem to solve for drug delivery systems. Despite the use of targeting units such as antibodies, peptides and proteins to increase their penetration in tumors the amount of therapeutics that reach the target is very small, even with the use of nanoparticles (NPs). Nature has solved the selectivity problem using a combination of proteins and lipids that are exposed on the cell membranes and are able to recognize specific tissues as demonstrated by cancer metastasis.

Integrative analysis of miRNA expression data reveals a minimal signature for tumour cells classification.

MicroRNAs (miRNAs) are pivotal biomarkers for cancer screening. Identifying distinctive expression patterns of miRNAs in specific cancer types can serve as an effective strategy for classification and characterization. However, the development of a minimal signature of miRNAs for accurate cancer classification remains challenging, hindered by the lack of integrated approaches that systematically analyse miRNA expression levels of miRNAs alongside their associated biological pathways.

Morphometric analysis revealed two different Mediterranean horse mackerel () stocks in the Adriatic Sea.

Phenotypical differentiation among individuals of Mediterranean horse mackerel in the Adriatic Sea was investigated through the analysis of several morphometric characters. Overall, 426 individuals of Mediterranean horse mackerels were sampled from the northern, central and southern Adriatic Sea during the summers of 2012 and 2013. Forty-six morphometric characters were measured for each individual and then compared using multivariate techniques (linear discriminant analysis).

A luminous and young galaxy at = 12.33 revealed by a JWST/MIRI detection of Hα and [O iii].

The James Webb Space Telescope has discovered a surprising population of bright galaxies in the very early Universe (≲500 Myr after the Big Bang) that is hard to explain with conventional galaxy-formation models and whose physical properties are not fully understood. Insight into their internal physics is best captured through nebular lines, but at these early epochs, the brightest of these spectral features are redshifted into the mid-infrared and remain elusive. Using the mid-infrared instrument onboard the James Webb Space Telescope, here we present a detection of Hα and doubly ionized oxygen ([O iii] 4959,5007 Å) from the bright, ultra-high-redshift galaxy candidate GHZ2/GLASS-z12.

The landscape of rare mitochondrial DNA variants in sudden cardiac death: A potential role for ATP synthase.

Sudden cardiac death (SCD) is a major health concern, which can be the sign of a latent mitochondrial disease. However, mitochondrial DNA (mtDNA) contribution is largely unexplored in SCD at population level. Recently, mtDNA variants have been associated with congenital cardiopathy and higher risk of ischemic heart disease, suggesting them as potential risk factors also in SCD.

Human head and neck cancer cell lines response to cold atmospheric plasma activated media is affected by the chemistry of culture media.

Survival rate of head and neck squamous cell carcinomas (HNSCC) patients are still to date very poor, and the application of innovative clinical approaches are urgently needed. Cold atmospheric plasmas (CAPs) are partially ionized gases that have shown anti-tumor effectiveness over a wide range of cancer types with potential application into clinics. However, the comprehension of the mechanisms underlying indirect CAP effects plays a key role for the prediction of treatment outcomes.
