Effects of cGMP/Akt/GSK-3 β signaling pathway on atrial natriuretic peptide secretion in rabbits with rapid atrial pacing
In conclusion, NPR-A interacts with ANP to regulate PGC expression, and influence the expression of cGMP during RAP, which involves in the Akt/GSK-3β signaling pathway. From the aforementioned points we conclude that cGMP regulates ANP secretion by the Akt/GSK-3β signaling pathway during atrial pacing. (Source: Frontiers in Physiology)

Protein disulfide isomerase A1 as a novel redox sensor in VEGFR2 signaling and angiogenesis
AbstractVEGFR2 signaling in endothelial cells (ECs) is regulated by reactive oxygen species (ROS) derived from NADPH oxidases (NOXs) and mitochondria, which plays an important role in postnatal angiogenesis. However, it remains unclear how highly diffusible ROS signal enhances VEGFR2 signaling and reparative angiogenesis. Protein disulfide isomerase A1 (PDIA1) functions as an oxidoreductase depending on the redox environment. We hypothesized that PDIA1 functions as a redox sensor to enhance angiogenesis. Here we showed that PDIA1 co-immunoprecipitated with VEGFR2 or colocalized with either VEGFR2 or an early endosome marke...

The Evaluation of Constant Coronary Artery Flow versus Constant Coronary Perfusion Pressure During Normothermic Ex Situ Heart Perfusion
Evidence suggests that hearts that are perfused under ex-situ conditions lose normal coronary vasomotor tone and experience contractile failure over a few hours. We aimed to evaluate the effect of different coronary perfusion strategies during ex situ heart perfusion on cardiac function and coronary vascular tone.

Surgical unroofing of myocardial bridges
Myocardial bridging occurs when an epicardial coronary artery has an intramyocardial segment that is compressed during systole, and may result in decreased perfusion pressure during early diastole (Figure 1) (9). The prevalence has been reported from one to five percent from angiographic series, although the true prevalence is likely much higher due to asymptomatic variants, as evidenced by much higher rates of incidence in autopsy series (10,11). The literature suggests that myocardial bridges may be responsible for serious adverse events such as myocardial ischemia, acute coronary syndromes, left ventricular dysfunction,...

The Protective Effect of Interval Exercise on Myocardial Ischemia-Reperfusion Injury in Players
Biomed Res Int. 2022 Aug 8;2022:4353340. doi: 10.1155/2022/4353340. eCollection 2022.ABSTRACTIn recent years, the popularity of sports has been increasing. In the high-intensity competition, many players have been injured; most of them are myocardial ischemia. With the development of medical science and technology, myocardial ischemia can be reperfusion. However, sometimes, the function of tissues and organs cannot be restored, but the dysfunction and structural damage of tissues and organs can be aggravated. Therefore, it is necessary to actively carry out intermittent exercise to protect players from myocardial ischemia-...

Early stage T1-weighted perfusion magnetic resonance imaging: a factor that predicts local control response in patients with meningioma who underwent gamma-knife radiosurgery
CONCLUSION: Changes between Ktrans on PO3M and pre-GKRS T1-PMRI were more useful in determining the early response to GKRS in patients with meningioma than volumetric changes. Therefore, Ktrans should be taken as a reference to predict the early response to GKRS in follow-up imaging scans.PMID:35981093 | DOI:10.1080/01616412.2022.2112377 (Source: Neurological Research)

Pathophysiology of cognitive dysfunction and the role of combined brain/heart magnetic resonance imaging (Review)
Exp Ther Med. 2022 Jul 14;24(3):569. doi: 10.3892/etm.2022.11506. eCollection 2022 Sep.ABSTRACTNormal cognitive function depends on a continuous and optimally regulated blood supply, and any pathology that further reduces cerebral blood perfusion in addition to that caused by aging could damage or destroy vulnerable neurons of the brain. Furthermore, glucose serves a crucial role as the primary fuel source for the mammalian brain and any disturbance in its circulating concentrations could directly affect brain function. The term cognitive dysfunction (CD), known also as 'brain fog', refers to deficits in attention, verbal ...

Cancers, Vol. 14, Pages 3997: Current Imaging Diagnosis of Hepatocellular Carcinoma
rassopoulos Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer related death worldwide. Radiology has traditionally played a central role in HCC management, ranging from screening of high-risk patients to non-invasive diagnosis, as well as the evaluation of treatment response and post-treatment follow-up. From liver ultrasonography with or without contrast to dynamic multiple phased CT and dynamic MRI with diffusion protocols, great progress has been achieved in the last decade. Throughout the last few years, pathological, biological, genetic, and immune-chemical analyses have revealed several tumoral...
