A Case Study of Aberrant Aortic Origin of the Right Coronary Artery.

This case report examines a rare cardiovascular abnormality, the Aberrant Aortic Origin of the Right Coronary Artery (AAORCA), in a 75-year-old patient with a history of myocardial infarction, acute renal injury, and cardiogenic shock. Rapid medical intervention, including coronary angioplasty, demonstrated the significance of prompt care. Chronic issues, including tobacco use and left ventricular dysfunction, complicated matters, emphasizing the importance of comprehensive long- term therapy.

Factors influencing failure of progression to completion hepatectomy following liver venous deprivation procedures (PVE or DVE): a longitudinal observational study.

Background: Two-staged hepatectomy (TSH) with portal (PVE) or dual vein embolization (DVE) gained acceptance in liver surgery. The current study assesses the incidence and causes of failure to progress to completion hepatectomy following PVE/DVE and its influence on overall survival (OS).

Methods: This is a longitudinal observational study of patients who underwent PVE or DVE between April 2010-December 2023.

A reproducible extended ex-vivo normothermic machine liver perfusion protocol utilising improved nutrition and targeted vascular flows.

Background: Normothermic machine perfusion of donor livers has become standard practice in the field of transplantation, allowing the assessment of organs and safe extension of preservation times. Alongside its clinical uses, there has been expanding interest in extended normothermic machine perfusion (eNMP) of livers as a potential vehicle for medical research. Reproducible extended normothermic machine perfusion has remained elusive due to its increased complexity and monitoring requirements.

Nitrogen and Sulfur Doped Porous Carbon Sheet with Trace Amount of Iron as Efficient Polysulfide Conversion Catalyst for High Loading Lithium-Sulfur Batteries.

The major challenges in enhancing the cycle life of lithium-sulfur (Li-S) batteries are polysulfide (PS) shuttling and sluggish reaction kinetics (S to LiS, LiS to S). To alleviate the above issues, the use of heteroatom-doped carbon as a cathode host matrix is a low-cost and efficient approach, as it works as a dual-functional framework for PS anchoring as well as an electrocatalyst for faster redox kinetics. Here, the dual role of heteroatom-doped carbon sheets (CS) in the chemisorption of LiS and catalysis of its faster conversion to LiS is established.

SIMAP500: A novel risk score to identify recipients at higher risk of hepatocellular carcinoma recurrence following liver transplantation.

Background: Recurrence of hepatocellular carcinoma (HCC) following liver transplantation (LT) has a devastating influence on recipients' survival; however, the risk of recurrence is not routinely stratified. Risk stratification is vital with a long LT waiting time, as that could influence the recurrence despite strict listing criteria.

Aim: This study aims to identify predictors of recurrence and develop a novel risk prediction score to forecast HCC recurrence following LT.
