Extracorporeal membrane therapy in a case of ruptured abscess on the mitroaortic intervalvular fibrosa associated to multisystem inflammatory syndrome: a case report.

Background: The mitroaortic intervalvular fibrosa is an avascular structure near the left ventricular outflow tract, between the mitral and aortic valves. Mitroaortic intervalvular fibrosa complications, such as tamponade, hemopericardium, and abscesses, are rare and often diagnosed postmortem. On the other hand, the COVID-19 pandemic notably impacted pediatric patients with congenital heart diseases, who frequently presented cardiac complications including arrhythmias, elevated troponins, myocarditis, and heart failure.

[Utility of CT Cardiac Angiography in the Evaluation of Infective Endocarditis and Its Complications].

Infective endocarditis (IE) is an infection that affects the heart valves, endocardium, and great vessels. It has a mortality rate of approximately 30% per year, so early diagnosis is essential to reduce morbidity and mortality. Cardiac angio-CT triggered by electrocardiogram (ECG) has been considered in IE management guidelines in recent years, given its high spatial resolution, contributing to the diagnosis and evaluation of valvular complications (vegetations, perforations, dysfunctions), perivalvular (abscesses, pseudoaneurysms, prosthesis dehiscence, fistulas) and compromised coronary arteries (embolism), allowing early diagnosis and treatment.

Pancreatic cancer cells infiltrate nerves through TGFbeta1-driven perineural epithelial-to-mesenchymal-like transdifferentiation.

Neural invasion is a prognostic hallmark of pancreatic ductal adenocarcinoma (PDAC), yet the underlying mechanisms behind the disruption of perineural barriers and access of cancer cells into intrapancreatic nerves remain poorly understood. This study aimed to investigate the role of epithelial-mesenchymal transformation (EMT) in perineural epithelial cells during neural invasion.Histopathological analysis of human and murine primary tumors using perineurium-specific GLUT1 antibody revealed a reduction in perineural integrity, which positively correlated with the extent of neural invasion in human PDAC cases.

Distribution and role of peripheral arterial chemoreceptors in cardio-respiratory control of the south american rattlesnake (Crotalus durissus).

Peripheral arterial chemoreceptors monitor the levels of arterial blood gases and adjust ventilation and perfusion to meet metabolic demands. These chemoreceptors are present in all vertebrates studied to date but have not been described fully in reptiles other than turtles. The goals of this study were to 1) identify functional chemosensory areas in the South American rattlesnake (Crotalus durissus) 2) determine the neurochemical content of putative chemosensory cells in these areas and 3) determine the role each area plays in ventilatory and cardiovascular control.

Compartmentalizing Donor-Acceptor Stenhouse Adducts for Structure-Property Relationship Analysis.

The development of photoswitches that absorb low energy light is of notable interest due to the growing demand for smart materials and therapeutics necessitating benign stimuli. Donor-acceptor Stenhouse adducts (DASAs) are molecular photoswitches that respond to light in the visible to near-infrared spectrum. As a result of their modular assembly, DASAs can be modified at the donor, acceptor, triene, and backbone heteroatom molecular compartments for the tuning of optical and photoswitching properties.

The In Vitro Cytotoxic Effect of Elesclomol on Breast Adenocarcinoma Cells Is Enhanced by Concurrent Treatment with Glycolytic Inhibitors.

Glycolysis and mitochondrial oxidative phosphorylation are the two major metabolic pathways for cellular ATP production. The metabolic plasticity displayed by cancer cells allows them to effectively shift between each of these pathways as a means of adapting to various growth conditions, thus ensuring their survival, proliferation and disease progression. Metabolic plasticity also provides cancer cells with the ability to circumvent many traditional monotherapies aimed at only one or the other of the major ATP-producing pathways.
