Vascular wall microenvironment: Endothelial cells original exosomes mediated melatonin-suppressed vascular calcification and vascular ageing in a m6A methylation dependent manner.

Vascular calcification and vascular ageing are "silent" diseases but are highly prevalent in patients with end stage renal failure and type 2 diabetes, as well as in the ageing population. Melatonin (MT) has been shown to induce cardiovascular protection effects. However, the role of MT on vascular calcification and ageing has not been well-identified.

Liraglutide Attenuates Aortic Valve Calcification in a High-Cholesterol-Diet-Induced Experimental Calcific Aortic Valve Disease Model in Apolipoprotein E-Deficient Mice.

Background: Calcific aortic valve disease (CAVD) is a significant cause of morbidity and mortality among elderly people. However, no effective medications have been approved to slow or prevent the progression of CAVD. Here, we examined the effect of liraglutide on aortic valve stenosis.

H19 Promotes Osteoblastic Transition by Acting as ceRNA of miR-140-5p in Vascular Smooth Muscle Cells.

Arterial medial calcification is a common disease in patients with type 2 diabetes, end-stage renal disease and hypertension, resulting in high incidence and mortality of cardiovascular event. H19 has been demonstrated to be involved in cardiovascular diseases like aortic valve diseases. However, role of H19 in arterial medial calcification remains largely unknown.

Circular RNA ciRs-126 promotes hypoxia/reoxygenation cardiac injury possibly through miR-21.

Background: This study aimed to analyze the role of circular RNA ciRs-126 in hypoxia/reoxygenation cardiac injury (H/R).

Methods: Expression of ciRs-126 and miR-21 in plasma samples from patients with H/R and healthy controls was determined by RT-qPCR. Correlations were analyzed by linear regression.

Cardiac inflammation and fibrosis following chemo/radiation therapy: mechanisms and therapeutic agents.

The incidence of cardiovascular disorders is one of the most concerns among people who underwent cancer therapy. The heart side effects of cancer therapy may occur during treatment to some years after the end of treatment. Some epidemiological studies confirm that heart diseases are one of the most common reasons for mortality among patients that were received treatment for cancer.

Deficiency of cGAS signaling protects against sepsis-associated encephalopathy.

Sepsis is a life-threatening inflammatory syndrome secondary to infection. Thanks to the advances of antibiotics and life-supporting techniques, the mortality of sepsis has been decreasing in recent decades. Nevertheless, sepsis-associated encephalopathy (SAE) is still common in septic patients, which promotes the mortality of septic patients and results in cognitive dysfunction in survivors.

Mediator complex proximal Tail subunit MED30 is critical for Mediator core stability and cardiomyocyte transcriptional network.

Dysregulation of cardiac transcription programs has been identified in patients and families with heart failure, as well as those with morphological and functional forms of congenital heart defects. Mediator is a multi-subunit complex that plays a central role in transcription initiation by integrating regulatory signals from gene-specific transcriptional activators to RNA polymerase II (Pol II). Recently, Mediator subunit 30 (MED30), a metazoan specific Mediator subunit, has been associated with Langer-Giedion syndrome (LGS) Type II and Cornelia de Lange syndrome-4 (CDLS4), characterized by several abnormalities including congenital heart defects.

Research status and the prospect of POSTN in various tumors.

The tumor microenvironment is considered one of the main players in tumor development and progression. The tumor microenvironment composed of a large number of extracellular matrix proteins is very complex. The continuous accumulation of extracellular matrix proteins has been shown to play a key role in tumor bioregulation, including proliferation, invasion, matrix remodeling.

Cardiolipin Remodeling Defects Impair Mitochondrial Architecture and Function in a Murine Model of Barth Syndrome Cardiomyopathy.

Background: Cardiomyopathy is a major clinical feature in Barth syndrome (BTHS), an X-linked mitochondrial lipid disorder caused by mutations in (), encoding a mitochondrial acyltransferase required for cardiolipin remodeling. Despite recent description of a mouse model of BTHS cardiomyopathy, an in-depth analysis of specific lipid abnormalities and mitochondrial form and function in an in vivo BTHS cardiomyopathy model is lacking.

Methods: We performed in-depth assessment of cardiac function, cardiolipin species profiles, and mitochondrial structure and function in our newly generated cardiomyocyte-specific knockout mice and Cre-negative control mice (n≥3 per group).

Adipose tissue-derived omentin-1 attenuates arterial calcification via AMPK/Akt signaling pathway.

Adipose tissue-derived adipokines mediate various kind of crosstalk between adipose tissue and other organs and thus regulate metabolism balance, inflammation state as well as disease progression. In particular, omentin-1, a newly found adipokine, has been reported to exhibit anti-calcification effects and . However, little is known about the function of endogenous adipose tissue-derived omentin-1 in arterial calcification and the detailed mechanism involved.

A Giant Cavernous Hemangioma of the Left Atrioventricular Groove.

A 10-year-old Chinese female diagnosed with an asymptomatic giant cardiac cavernous hemangioma was reported. The patient originally tended to observation because this unusual cardiac tumoral mass was discovered incidentally during routine health examination of transthoracic echocardiography. Over 5 years of follow-up, the mass had enlarged obviously, and the patient visited our outpatient clinic and was prone to excision.

Association Between the Left Atrial and Left Atrial Appendages Systole Strain Rate in Patients with Atrial Fibrillation.

BACKGROUND The aim of this research was to explore the association between the left atrial (LA) and left atrial appendages (LAA) systole strain rate (SSR) in patients with atrial fibrillation (AF), and to provide evidence to aid in the assessment of disease progression. MATERIAL AND METHODS A total of 180 patients with AF were selected for the study (130 patients with paroxysmal AF (Par AF) and 50 patients with persistence AF (PerAF).In addition, 60 healthy individuals were selected as a control group.

Isolated cardiac peripheral primitive neuroectodermal tumor: A case report.

Background: Peripheral primitive neuroectodermal tumor isolated in the heart, presenting as a primary cardiac tumor is considered as extremely rare.

Methods: We present a 53-year-old Chinese female with a cardiac tumor which was discovered by CT.

Results: A hypo-intense tumorous mass was shown extending from the left ventricle by Cardiac CT, and fused FDG positron emission tomography demonstrated no other abnormal FDG active lesions in the body.

The Relationship between Galectin-3 and Different Patterns of Ventricular Geometry Remodelling in Aortic Valve Stenosis.

Background: This study was conducted to assess expression of Galectin-3 (Gal-3) in patients with different types of left ventricle (LV) hypertrophy geometry, and the relationship between Gal-3 expression and LV remodelling in patients with aortic valve stenosis (AS).

Methods: Galectin-3 expression was measured in the plasma and myocardia of AS patients who underwent an aortic valve replacement procedure.

Results: The study enrolled 77 consecutive patients with severe AS.

Apelin attenuates the osteoblastic differentiation of aortic valve interstitial cells via the ERK and PI3-K/Akt pathways.

Aortic valve calcification (AVC), which used to be recognized as a passive and irreversible process, is now widely accepted as an active and regulated process characterized by osteoblastic differentiation of aortic valve interstitial cells (AVICs). Apelin, the endogenous ligand for G-protein-coupled receptor APJ, was found to have protective cardiovascular effects in several studies. However, the effects and mechanisms of apelin on osteoblastic differentiation of AVICs have not been elucidated.

Effects of remote ischemic preconditioning on the flow pattern of the left anterior descending coronary artery in normal subjects.

Remote ischemic preconditioning (RIPC) has been proposed as an effective method to improve both myocardial and vascular protection in human beings. The aim of this study was to identify the effect of RIPC on the flow pattern of left anterior descending coronary artery (LAD) by transthoracic Doppler echocardiography. 18 normal male volunteers were enrolled to this study.
