Magnetoelastic Cell Monitoring System for Evaluating the Effects of Surface Chemistry on the Performance of Mesenchymal Stem Cell Growth

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The recent clinical adoption of cell therapies has increased the need for more efficient, robust, and reproducible manufacturing technologies. Human mesenchymal stromal cells (hMSCs), a major component of the cell and immunotherapeutic market, remain challenging to manufacture at scale because they require surface attachment and are highly ...

Determining the Nutritional Potential of Ancient Wheat Species: A Closer Look at Starch and Protein Digestibility, and Phenolic Acid Content

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives The recent trend towards healthy food choices and sustainable agriculture has revived interest in underutilized wheat species such as emmer, einkorn, and spelt. Given these developments, the objective of the study was to compare the differences in chemical composition and digestibility characteristics among ...

Homo‐/Heterodimeric Substrates Bias the Type and Multiplicity of Hydroxamic Acid Chelators Assembled by a NIS Synthetase DesD

Chemistry – A European Journal, EarlyView.
Chemoenzymatic reactions using the siderophore synthetase DesD from Salinispora tropica and hydroxamic acid substrates (native, non‐native) with different multiplicities (monomer, dimer) and components (homo‐/heterodimer) followed different reaction trajectories, which biased the architectures of the chelator major products and indicated DesD contains ...

Transposon Defense by Endo-siRNAs, piRNAs and Somatic pilRNAs in Drosophila: Contributions of Loqs-PD and R2D2

PLoS ONE, 2014
Transposable elements are a serious threat for genome integrity and their control via small RNA mediated silencing pathways is an ancient strategy. The fruit fly Drosophila melanogaster has two silencing activities that target transposons: endogenous siRNAs (esiRNAs or endo-siRNAs) and Piwi-interacting small RNAs (piRNAs). The biogenesis of endo-siRNAs

Payload‐Based Clinical Pharmacology Review of Approved Antibody–Drug Conjugates: Commonalities and Considerations for Streamlined Development

Clinical Pharmacology &Therapeutics, EarlyView.
Antibody–drug conjugates (ADCs) combine the specificity of an antibody with the potency of a cytotoxic drug. Thirteen ADCs, utilizing seven unique cytotoxic payloads and targeting 11 distinct antigens, are currently approved by the US Food and Drug Administration as of June 2025, representing a rapidly growing and highly promising class of anticancer ...
