High‐sensitivity real‐time monitoring of pH and respiration activity unveils metabolic dynamics in shake flask cultures

Biotechnology Progress, Volume 41, Issue 2, March/April 2025.
Abstract Erlenmeyer shake flasks are widely used during the first steps of bioprocess development. Despite their broad application in academia and industry, shake flasks usually lack standardized and user‐friendly online monitoring techniques. In this work, the pH and Respiratory Activity MOnitoring System (pH‐RAMOS) for the non‐invasive online ...

Detergent/surfactant retention during ultrafiltration in the formulation of biotherapeutics

Biotechnology Progress, EarlyView.
Abstract Surfactants like polysorbate (Tween®) are commonly used as excipients in the production of monoclonal antibodies and other recombinant proteins. The retention behavior of these excipients in the final ultrafiltration step can be difficult to predict due to the presence of both monomers and micelles.

Incorporating Clinical Examination Skills Into a Preclinical Anatomy Course: A Method for Facilitating Engagement and Interest

Clinical Anatomy, EarlyView.
ABSTRACT Anatomy instruction is enhanced when students are engaged and interested in course material, and the relevance of the subject matter to their academic success and professional careers is emphasized. We developed a learning activity for a pre‐clinical anatomy course using the clinical skills of inspection and palpation of a cadaver donor to ...

Phytochemical Profile and Anticancer Activity of Achillea conferta Leaf Extracts: Insights Into Antioxidant Properties

Chemistry &Biodiversity, EarlyView.
ABSTRACT This study explores the phytochemical composition and biological potential of extracts from Achillea conferta leaves, specifically hydroethanolic extract (HE), total flavonoid extract (TFE), and glycoside flavonoid extract (GFE). Phytochemical screening of HE revealed significant concentrations of phenolic compounds, flavonoids, and tannins ...
