Biochar-enhanced three-dimensional conductive network thick electrodes for efficient lithium extraction from salt lake brines with high Magnesia-lithium ratios.

Enhancing the kinetic performance of thick electrodes is essential for improving the efficiency of lithium extraction processes. Biochar, known for its affordability and unique three-dimensional (3D) structure, is utilized across various applications. In this study, we developed a biochar-based, 3D-conductive network thick electrode (∼20 mg cm) by in-situ deposition of LiFePO (LFP) onto watermelon peel biomass (WB).

Modified cavoatrial anastomosis in Warden procedure.

The Warden procedure was introduced for surgical repair of partial anomalous pulmonary venous connection to the higher portion of the superior vena cava in an attempt to decrease the incidence of postoperative sinoatrial node dysfunction and pulmonary venous obstruction. However, postoperative cavoatrial channel stenosis and obstruction up to 20% and 10%, respectively, requiring catheter intervention has been reported. In this article, we describe a modified cavoatrial anastomotic technique to avoid postprocedural superior vena cava stenosis.

How to choose an occluder for two nearby muscular ventricular septal defects?

Multiple muscular ventricular septal defects treated with a single device have been reported before, but the way of choosing a suitable occluder is not well described. Implantation of an oversized device might lead to potential side effects. We described our experience with a single device to close two nearby muscular ventricular septal defects perventricularly, and specifically the decision-making process used to choose the suitable occluder.

Association between transforming growth factor-beta 1 polymorphism and virologic characteristics of chronic hepatitis C.

The production of transforming growth factor beta 1 (TGF-beta1) has been reported as being significantly associated with the gene polymorphism in the leader sequence at positions +29. The current study aimed to evaluate the associations between the polymorphism and the clinical characteristics of chronic hepatitis C (CHC). A total of 422 (252 men; mean age: 49.

Perventricular device closure of ventricular septal defects: six months results in 30 young children.

Background: Both surgical repair and transcatheter closure of isolated ventricular septal defects are known to have limitations in children. This report describes the short-term results of perventricular device closure of nonmuscular ventricular septal defects without cardiopulmonary bypass in young children.

Methods: Thirty patients who had nonmuscular ventricular septal defects underwent perventricular closure by minimally invasive technique without cardiopulmonary bypass.

Malignant lymphoma of spleen presenting as acute pancreatitis: a case report.

This is a case report of a patient who presented with acute pancreatitis without the common causes. A pancreatic biopsy revealed large B cell lymphoma. Spleen lymphoma with pancreatic involvement inducing acute pancreatitis, which is a rare disorder, was diagnosed.
