Novel glucodendrimers scaffolds containing α-d-glucopyranoside at the surface and triazole as bridging unit have been synthesized. Cardiomyocytes were exposed to normal and high glucose level in the presence and absence of glucodendrimers. Cytotoxicity studies were also carried out and the expression of metalloproteinases mainly MMP-2 and 9 was confirmed with gelatine zymography and RT-PCR gene expression studies. Cardio protective efficiency of the synthesized glucodendrimers against high glucose induced toxicity on mettalloproteinase-2 and 9 and also on H9C2 cell lines revealed that higher generation glucodendrimers 6 and 8 are more effective than the lower generation glucodendrimers.

Diabetic cardiomyopathy (DMCM), defined as left ventricular dysfunction in the setting of diabetes mellitus without hypertension, coronary artery disease or valvular heart disease, is a well-recognized entity whose prevalence is certainly predicted to increase alongside the rising incidence and prevalence of diabetes mellitus. The pathophysiology of DMCM stems from hyperglycemia and insulin resistance, resulting in oxidative stress, inflammation, cardiomyocyte death, and fibrosis. These perturbations lead to left ventricular hypertrophy with associated impaired relaxation early in the course of the disease, and eventually culminating in combined systolic and diastolic heart failure.

Ischemia-reperfusion injury is a serious clinical pathology involving multiple organs such as the heart and brain. The injury results from oxidative stress, inflammatory response and cell death triggered by restoring tissue blood flow after ischemia, leading to severe cell and tissue damage. In recent years, the volume-regulated anion channel (VRAC) has gained attention as an important membrane protein complex.

Introduction: Heart failure with preserved ejection fraction (HFpEF) is a complex condition characterized by metabolic dysfunction and myocardial lipotoxicity. The roles of PTEN-induced kinase 1 (PINK1) and peroxiredoxin-2 (Prdx2) in HFpEF pathogenesis remain unclear.
Objective: This study aimed to investigate the interaction between PINK1 and Prdx2 to mitigate cardiac diastolic dysfunction in HFpEF.

Background: Approximately 30% of patients with atrial fibrillation suffer from depression. Depression in patients with atrial fibrillation is associated with poor health outcomes, reduced health-related quality of life, and elevated societal costs. Preventing depression in this population may therefore lead to better health outcomes for the individual patient and reduced burden on society.

Cardiopulmonary resuscitation (CPR) after cardiac arrest (CA) is an important cause of neurological impairment and leads to considerable morbidity and mortality. The stability of the blood-brain barrier (BBB) is crucial for minimizing secondary neurological damage and improving long-term prognosis. However, the precise mechanisms and regulatory pathways that contribute to BBB dysfunction after CPR remain elusive.
