This paper presents improvement in lead (Pb) recovery and sulphate removal from used Pb acid battery (ULAB) through Electrokinetic technique, a process aimed to eliminate environmental pollution that arises due to emission of gases and metal particles from the existing high temperature pyrometallurgical process. Two different cell configurations, (1) one with Nafion membrane placed between anode and middle compartments and Agar membrane between cathode and middle compartments and (2) another with only Agar membrane placed between both sides of the middle compartments were designed for the Pb and sulphate separation from ULAB. This paper concludes that the cell with only Agar membranes performed better than the cell with Nafion and Agar membranes in combinations and also explains the mechanism underlying the chemical and electrochemical processes in the cell.

Dynamic biomechanical effects of medial meniscus tears on the knee joint: a finite element analysis.
J Orthop Surg Res
January 2025
Key Laboratory for Biomechanics and Mechanobiology of Ministry of Education, Beijing Advanced Innovation Center for Biomedical Engineering, School of Biological Science and Medical Engineering, Beihang University, Beijing, 100083, China.
Background: Meniscus tears can change the biomechanical environment of the knee joint and might accelerate the development of osteoarthritis. The aim of this study was to investigate the dynamic biomechanical effects of different medial meniscus tear positions and tear gaps on the knee during walking.
Methods: Seven finite element models of the knee joint were constructed, including the intact medial meniscus (IMM), radial stable tears in the anterior, middle, and posterior one-third regions of the medial meniscus (RSTA, RSTM, RSTP), and the corresponding unstable tears (RUTA, RUTM, RUTP).
Phenotypic diversity of CTCs and tdEVs in liquid biopsies of tumour-draining veins is linked to poor prognosis in colorectal cancer.

Background: Circulating tumour cells (CTCs) and tumour-derived extracellular vesicles (tdEVs) have great potential for monitoring therapy response and early detection of tumour relapse, facilitating personalized adjuvant therapeutic strategies. However, their low abundance in peripheral blood limits their informative value. In this study, we explored the presence of CTCs and tdEVs collected intraoperatively from a tumour-draining vein (DV) and via a central venous catheter (CVC) prior to tumour resection.

: Sodium glucose cotransporter-2 (SGLT-2) inhibitors have emerged as integral therapeutic tools in the management of patients with cardiovascular-kidney-metabolic (CKM) syndrome. In addition to their well-documented effects on lowering glucose levels and cardiovascular- and reno-protective actions, SGLT-2 inhibitors, through a reduction in body weight (BW), generate changes in the body composition and volume status that have not been clearly studied. : This retrospective, observational longitudinal cohort, single-center study analyzed and compared body composition and fluid status measured by bioelectrical impedance analysis (BIA) from weeks 0 to 12 after the initiation of the cardiac rehabilitation (CR) program for coronary artery disease and heart failure in 59 patients who started treatment with SGLT-2 inhibitors (SGLT-2iG) and 112 patients without SGLT-2 inhibitors (non-SGLT-2iG).

: Metabolic dysfunction-associated steatotic liver disease (MASLD) is an important chronic liver disease with major health risks, especially in the presence of T2DM, but the pathophysiology of this condition is not fully understood. This study aimed to investigate the platelet hematometric indices in patients with T2DM and MASLD. : Demographic and medical (including anthropometric) data were collected from 271 participants, from whom blood samples were also drawn in fasting conditions for complete blood count, liver and metabolic panel, ferritin, haptoglobin, creatinine, and fibrosis markers.
