Summary: This study investigated the potential of using nitric oxide-loaded microbubbles and ultrasound to treat thromboembolism. The results showed that this treatment significantly reduced thrombus area, increased recanalization rates and blood flow velocities. The treatment also activated endothelial nitric oxide synthase and mitigated oxidative stress and apoptosis.

Summary: Our study demonstrates that deletion of the gamma subunit of ENaC, while allowing for greater activation of eNOS, is not sufficient to prevent IRI. This suggests that the protective effects of alpha subunit deletion may be due, in part, to other mechanisms.

Summary: This study reveals a critical role for endothelial cell Gch1/BH4 biosynthesis in coronary vascular function and cardiac function. Loss of cardiac endothelial cell BH4 leads to coronary vascular dysfunction, reduced functional recovery, and increased myocardial infarct size following ischemia/reperfusion injury. Targeting endothelial cell Gch1 and BH4 biosynthesis may provide a novel therapeutic target for the prevention and treatment of cardiac dysfunction, ischemia injury, and heart failure.

Summary: Long-term nitrate intervention increased the resistance to myocardial ischemia-reperfusion injury (MIRI) in female rats, which was associated with increased heart endothelial nitric oxide synthase (eNOS) expression and circulating progesterone before ischemia and blunting ischemia-induced increased inducible nitric oxide synthase (iNOS) and decreased eNOS after MIRI.

Summary: This study evaluated the effects of trehalose preconditioning on cardiac and coronary endothelial function after ischemia-reperfusion injury. It was found that trehalose preconditioning improved heart function, reduced edema, oxidative stress, and apoptosis, and increased eNOS dimerization ratio, indicating its protective effects on cardiac and coronary endothelial function. These effects were mediated through the eNOS signaling pathway.

Summary: In this study, modulation of NO bioavailability through exogenous application of NOSs and L-arginine significantly attenuated ischemia-reperfusion-induced alterations in a type 2 diabetic skin flap rat model, with the best results achieved with the combination of eNOS and L-arginine. Higher enzyme dosage seemed to be less effective in improving flap vitality rates.

Summary: This study demonstrates that short-term, mild exercise induces delayed cardioprotective effects against myocardial infarction, dependent on the activation of eNOS, eNOS-derived NO generation, and subsequent PKC epsilon activation during preconditioning. Furthermore, the protection 24 hours after exercise is mediated by iNOS activity.

Summary: Ischemia-reperfusion injury (IRI) is a damage process induced in hypoxic tissue when oxygen is supplied after ischemia. Restoration of reduced nitric oxide (NO) levels may alleviate reperfusion injury in ischemic organs, with the protective mechanism due to anti-inflammatory and antioxidant effects of NO, as well as regulation of cell signaling pathways. S-nitrosylation (SNO) mediates the detrimental or protective effect of NO depending on the nitrosylated target protein, which also plays a role in the IRI process.

Summary: Brain ischemia and reperfusion (I/R) is a severe manifestation of ischemic stroke. Accumulating evidence suggests that nitric oxide (NO) plays a crucial role in the pathological processes of brain I/R, including neuronal cell death and blood-brain barrier disruption. This review focuses on the role of endogenous NO in brain I/R and discusses therapeutic approaches associated with NO.

Summary: This study presents the potential of near infrared dye IR-780 for monitoring and protecting ischemic myocardium from injury. IR-780 selectively enters cardiomyocytes in at-risk heart tissues and can preconditon or administer timely to protect against cell death, myocardial remodeling, and heart failure induced by ischemia and oxidative stress. The dye binds to F0F1-ATP synthase in cardiomyocytes, decreases mitochondrial membrane potential, and slows down mitochondrial energy metabolism, leading to a quiescent mitochondria state and inhibition of mitochondrial permeability transition pore. Moderating mitochondrial function depression could be a targeted approach for developing cardioprotective reagents.

Summary: This study reveals that red blood cell endothelial nitric oxide synthase (RBC eNOS) plays a role in limiting infarct size in acute myocardial infarction (AMI) and regulates coronary blood flow and cardiac function. These findings suggest that RBC eNOS signaling may represent a novel target for interventions in ischemia/reperfusion after myocardial infarction.

Summary: Cerebral ischemia and reperfusion injury can lead to poor oxygen supply, brain infarction, and an imbalance in mitochondrial dynamics, which plays a crucial role in cell survival and infarct area size regulation. Understanding and regulating mitochondrial dynamics may help prevent or treat cerebral injury.

Summary: This study provides deeper insights into the genetic risk architecture of bicuspid aortic valve (BAV) disease, including both single-marker and polygenic levels. The study identified a new risk locus and confirmed previously reported risk loci. Additionally, the study revealed that the transcriptome profile in endothelial cells plays a major role in the pathology of BAV.

Summary: This study investigated the risk factors for device-related thrombus (DRT) after left atrial appendage closure (LAAC). The results found that age, prior stroke/TIA, and spontaneous echocardiographic contrast (SEC) were associated with DRT, and implantation depth was a predictive factor. The occurrence of stroke/TIA was higher in patients with DRT.

Summary: Spin-lock based functional magnetic resonance imaging (fMRI) has the potential to directly detect neuronal activity and advance basic research in neuroscience. This study investigated the Rotary EXcitation (REX) effect through simulations, phantom, and in vivo experiments, discovering an empirical law for predicting optimal spin-lock pulse durations. The study also established experimental conditions for robust detection of ultra-weak magnetic field oscillations with compensation for static field inhomogeneities. Additionally, a novel concept for emulating brain activity using the MRI gradient system was presented, allowing validation of REX sequences under controlled conditions. Transmission of Rotary EXcitation (tREX) successfully detected magnetic field oscillations in the lower nano-Tesla range in brain tissue, opening up possibilities for biomagnetic field quantification.

Summary: This study evaluates the association between timing of active left ventricular (LV) unloading and implantation of VA-ECMO with outcomes in patients with cardiogenic shock (CS). The results show that early active LV unloading is associated with a lower risk of 30-day mortality and a higher likelihood of successful weaning from ventilation, without increasing complications.

Summary: This study investigated the prognostic value of dynamic changes in left ventricular ejection fraction (EF) for cardiovascular outcomes in heart failure patients with reduced EF. The study found that improvement in EF is independently associated with longer survival and lower cardiovascular mortality and hospitalization rate in HFrEF patients. Elevated baseline NT-proBNP is identified as the strongest prognostic factor associated with increased cardiovascular events risk in HFrEF patients, regardless of EF improvement, age, sex, duration of HF, and other clinical risk factors.

Summary: This study analyzed 176 patients with device-related thrombus (DRT) after left atrial appendage closure (LAAC) and found that 14.2% experienced ischemic stroke or systemic embolism (SE). Of these events, 45.8% occurred within one month before or after DRT diagnosis. Patients with symptomatic DRT had lower left ventricular ejection fractions and higher rates of non-paroxysmal atrial fibrillation.

Summary: This study investigated the ability of morphological features of infarcted myocardium to detect acute left ventricular dysfunction and predict left ventricular functional recovery after three months in patients with acute ST-segment elevation myocardial infarction (STEMI). The results showed that the CMR tissue characteristics of myocardial injury are correlated with the magnitude of left ventricular dysfunction during the acute stage of STEMI, and the area-at-risk predicts improvement in left ventricular ejection fraction and global longitudinal strain, while the myocardial salvage index is a sensitive marker of left ventricular global circumferential strain recovery at three months follow-up after STEMI.
