Quality by Design in continuous bioprocessing: Investigating the impact of critical process parameters of multi-column chromatography during steady-state and transient phases.

Given the complexities of continuous bioprocessing, it is critical to thoroughly investigate the process parameters unique to multi-column chromatography (MCC) and their potential impacts. However, existing studies have focused on either loading densities or residence time at steady states only, and their combined impact on critical quality attributes (CQAs) especially during transient phases were less known. In this study, we investigated the impact of critical process parameters during both steady-state and transient phases (start-up, close-down, and intermediate perturbation) through full factorial design.

Exploring cost reduction strategies for serum free media development.

Cultivated meat production offers solutions in addressing global food security and sustainability challenges. However, serum-free media (SFM) used in cultivating the cells are expensive, contributing to at least 50% of variable operating costs. This review explores technologies for cost-effective SFM, focusing on reducing cost from using growth factors and recombinant proteins, using affordable raw materials for basal media, and implementing cost-saving measures like media recycling and reducing waste build-up.

The risk of death according to left ventricular ejection fraction and right ventricular dilatation in 17 321 adults with heart failure from 40 high-, middle- and low-income countries - A Global Congestive Heart Failure (G-CHF) study.

Aims: The aim of this study was to describe the prognostic importance of left ventricular ejection fraction (LVEF) versus right ventricular (RV) dilatation and dysfunction in patients with heart failure (HF) from countries of different income levels.

Methods And Results: We enrolled 17 321 participants with HF from 40 countries. Participants were followed for a median (25th-75th percentile) of 2.

Influencing inter-cellular junctions with nanomaterials.

Cell-cell junctions are essential for maintaining tissue integrity and regulating a wide range of physiological processes. While the disruption of intercellular junctions may lead to pathological conditions, it also presents an opportunity for therapeutic interventions. Nanomaterials have emerged as promising tools for modulating cell-cell junctions, offering new avenues for innovative treatments.

Digging deep for nutrients and metabolites derived from high dietary protein intake and their potential functions in metabolic health.

Intake of high quantities of dietary proteins sourced from dairy, meat or plants can affect body weight and metabolic health in humans. To improve our understanding of how this may be achieved, we reviewed the data related to the availability of nutrients and metabolites in the faeces, circulation and urine. All protein sources (≥20% by energy) increased faecal levels of branched chain fatty acids and ammonia, and decreased the levels of butyrate.
