A Computational Approach for Biomimetic Design of Liver‐On‐A‐Chip

open access: yesAdvanced Intelligent Discovery, EarlyView.
A biomimetic liver‐on‐a‐chip with antiparallel perfusion was designed using COMSOL‐guided simulation to replicate hepatic acinus transport. Full‐scale modelling revealed diffusion‐dominated, length‐dependent nutrient gradients and low‐shear conditions.

Navigating Asparaginase Treatment for Patients With Acute Lymphoblastic Leukemia: US Consensus Panel Recommendations on the Role of Multidisciplinary Care

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Asparaginase is a critical treatment component for patients with acute lymphoblastic leukemia/lymphoblastic lymphoma (ALL/LBL). However, the successful delivery of asparaginase‐based therapy remains challenging across care settings due to its complex administration, distinct toxicity profile, prolonged treatment duration, and the need for ...
