Portal vein recanalization and transjugular intrahepatic portosystemic shunt in chronic portal vein thrombosis: a narrative review

Mejía-Quiñones, Valentina · Lotero-Robledo, José Gabriel · Hidalgo-Oviedo, José Miguel · Toro-Gutiérrez, Juan S. · y 1 más

Portal vein thrombosis (PVT) is a heterogeneous and clinically significant complication of liver cirrhosis, primary hepatobiliary malignancy, and various systemic prothrombotic states. It is associated with advanced portal hypertension, increased surgical complexity during liver transplantation, and higher mortality. T...

Jeffrey Guevara-Corzo

Initial public release of MMA-Algorithm-FORTRAN. This version provides a FORTRAN implementation of the Method of Moving Asymptotes (MMA) based on the original algorithm developed by Professor Krister Svanberg. The implementation is intended for academic and research purposes and requires the LAPACK library for the line...

Case Report: Single-access epidural adhesiolysis and catheter-delivered pulsed radiofrequency for refractory failed back surgery syndrome

Nascimento, Rafael

Failed back surgery syndrome (FBSS) frequently involves mixed mechanical, inflammatory, and neuropathic mechanisms and remains challenging to treat, particularly when systemic anti-inflammatory therapy is limited. We report a 55-year-old woman with chronic refractory left lumbosciatica after endoscopic lumbar discectom...

Levelized Cost of Electricity (LCOE) Assessment of Bifacial PV Systems in Uribia, Colombia: Integrating Stochastic Simulation and Machine Learning Under Fiscal Incentives

Yimy Garcia Vera · Jaime Pérez · Edwin Villarreal-López

This study evaluates the techno-economic viability of bifacial photovoltaic (PV) systems in Uribia, La Guajira—the department that holds Colombia’s strongest solar resource, with a mean global horizontal irradiance near 5.6 kWh/m2/day and seasonal peaks above 6.0. Despite this endowment, the country’s installed solar c...

By-products of insect farming as a novel sustainable biofertilizer for crops

Barragán Fonseca, Katherine Y. · Mertens, Daan · Beschoren da Costa, Pedro · van Loon, Joop J. A. · y 1 más

Abstract The development of sustainable high-yield farming practices is crucial to support a growing human population while providing long-term solutions for the environmental impact of intensified agriculture. Nutrient-rich bio-residuals generated through the industrial production of insects hold a high but underexplo...
