Effect of miR-223-3p and miR-328a-3p Knockdown on Allergic Airway Inflammation in Rat Precision-Cut Lung Slices.

Asthma is a major non-communicable disease whose pathogenesis is still not fully elucidated. One of the asthma research models is precision-cut lung slices (PCLSs), and among the therapeutic options, miRNA molecules are of great interest. The aim of our study was to investigate whether inhibition of miR-223-3p and miR328a-3p affects the inflammatory response in PCLSs derived from a rat with HDM-induced allergic inflammation and a control rat.

MicroRNA Expression Profile Is Altered by Short-Term and Chronic Lithium Treatment in a Rat Model of Depression.

Depression is a common disease that affects 3.8% of the global population. Despite various antidepressant treatments, one-third of patients do not respond to antidepressants, therefore augmentation with mood stabilizers such as lithium may be required in this group.

An optimized QIAzol-based protocol for simultaneous miRNA, RNA, and protein isolation from precision-cut lung slices (PCLS).

Background: Precision-cut lung slices (PCLS) are ex vivo models with preserved lung cell populations and maintained tissue architecture. PCLS are, therefore, a powerful tool in respiratory research to study molecular mechanisms that closely reflect whole tissue biology. High-quality RNA and protein extraction from PCLS is, however, challenging as agarose significantly interferes with the yield and purity of extracted material.

Perceval ViV-TAVR: Perception Is Not Always Reality.

Valve-in-valve transcatheter aortic valve replacement for failed Perceval sutureless valves has been shown to be safe and feasible. However, it is technically challenging and warrants understanding of potential risks and complications. We present a case of successful valve-in-valve implantation complicated by inadvertent wire passage outside of the Perceval frame.

Patients with heart failure and reduced ejection fraction: A sub-analysis from the 3-year Coordinated Myocardial Infarction Care Program (KOS-MI) registry.

Background: The Coordinated Care Program after Myocardial Infarction (KOS-MI) implemented in Poland has shown significant improvement in patient prognosis, ended in nationwide success, and got international attention. A similar program and methodology may be an attractive option for patients with heart failure (HF).

Aims: This study aimed to analyze whether a similarly structured program would also be beneficial for HF patients after myocardial infarction.
