In cultures with efficient aeration a maximum cell concentration (MCC) of 6 X 10(5) cells/ml (defined medium) and 5.5 X 10(6) cells/ml (broth) can be reached. By culturing within Millicells with excess supply of medium and efficient removal of waste products a physical limit for MCC of about 13 X 10(6) cells/ml is reached.

Therapeutic efficacy and safety of adeno-associated virus (AAV) liver gene therapy depend on capsid choice. To predict AAV capsid performance under near-clinical conditions, we established side-by-side comparison at single-cell resolution in human livers maintained by normothermic machine perfusion. AAV-LK03 transduced hepatocytes much more efficiently and specifically than AAV5, AAV8 and AAV6, which are most commonly used clinically, and AAV-NP59, which is better at transducing human hepatocytes engrafted in immune-deficient mice.

The utilization of cyanobacteria toxin-producing blooms for metal ions adsorption has garnered significant attention over the last decade. This study investigates the efficacy of dead cells from Microcystis aeruginosa blooms, collected from agricultural drainage water reservoir, in removing of cadmium, lead, and zinc ions from aqueous solutions, and simultaneously addressing the mitigation of toxin-producing M. aeruginosa bloom.

Purpose: Posterior fossa ring-enhancing lesions (PFREL) in the adult immunocompetent hosts pose a diagnostic challenge. We aimed to evaluate the spectrum of PFREL etiologies and propose a diagnostic algorithm.
Methods: This study involved a retrospective analysis of PFREL cases from our institution (January 2023 to April 2024) and a systematic literature review conducted using Embase and PubMed databases following the PRISMA 2020 guidelines.

Coelomic fluid of earthworms is a valuable source of novel bioactive compounds with therapeutic applications. To gain insight into the bioactive compounds in the coelomic fluid, this study used Perionyx excavatus, a tropical earthworm distinguished for its remarkable ability for regeneration. This study aimed to identify fluorescent bioactive compounds in the coelomic fluid of P.

The increasing prevalence of micropollutants like cationic and anionic dyes in wastewater creates an influential environmental challenge, mainly due to their toxic effects and persistence. Current methods often lack the efficiency and versatility to cope with a wide variety of contaminants. This study explores the modification of TEMPO-oxidized cellulose nanofibers (TOCNF) using (3-chloro-2-hydroxypropyl) trimethylammonium chloride (CHPTAC) to enhance their cationic properties.
