Comparison of Embolization Coils and Patent Ductus Arteriosus Occluders for Coronary Artery Fistula Transcatheter Closure: A Single Centre Experience.

Background And Objectives: There is no dedicated occlusive device for closing coronary artery fistulas (CAFs), and specific efficacy and safety data of various off-label occlusive devices for CAFs closure are scarce.

Methods: Patients undergoing transcatheter closure of CAFs from January 2011 to December 2022 were included in the single-center retrospective study. The study population was divided into 2 groups: coils group (n=35) and patent ductus arteriosus (PDA) occluders group (n=66).

Seasonal shifts in respiratory pathogen co-infections and the associated differential induction of cytokines in children.

In the post-pandemic era, research on respiratory diseases should refocus on pathogens other than the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Respiratory pathogens, highly infectious to children, with to different modes of infection, such as single-pathogen infections and co-infections. Understanding the seasonal patterns of these pathogens, alongside identifying single infections and co-infections and their impact on the pediatric immune status, is crucial for clinical diagnosis, treatment, and prognosis in children.

Development of a Self-Deploying Extra-Aortic Compression Device for Medium-Term Hemodynamic Stabilization: A Feasibility Study.

Hemodynamic stabilization is crucial in managing acute cardiac events, where compromised blood flow can lead to severe complications and increased mortality. Conditions like decompensated heart failure (HF) and cardiogenic shock require rapid and effective hemodynamic support. Current mechanical assistive devices, such as intra-aortic balloon pumps (IABP) and extracorporeal membrane oxygenation (ECMO), offer temporary stabilization but are limited to short-term use due to risks associated with prolonged blood contact.

Design and mechanical properties analysis of drill pipe's joint thread with unequal taper under complex loads.

The design of drill pipe joint thread with unequal taper is proposed to investigate the fracture failure of the API NC38 used in the drill pipe joint of the SU36-8-4H2 well. The effect of changes in thread taper on the stress distribution and mechanical properties of drill pipe joints is analyzed and compared with the API standard thread to determine the optimal thread structure with unequal taper. The results reveal highly concentrated stress at the last engaged thread root of API NC38 single-shoulder thread (SUT) may cause early yield failure of the joint threads.

Enhancing Digestibility and Intestinal Peptide Release of Protein: An Enzymatic Approach.

is a tasty and low-calorie mushroom containing abundant high-quality protein. This study aims to improve the digestibility of protein (PEP) and hence to facilitate its development as a healthy alternative protein. The extracted PEP was pretreated with 1000-5000 U of papain, neutral protease and alkaline protease.
