Isolating T‐Cell Potent Lentiviral Vector Subpopulations through Rational Design of Nanofiber Anion‐Exchange Adsorbents

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Generation of CAR‐T cell therapies relies predominantly on lentiviral vectors (LVs). As in vivo CAR‐T trials progress, demand for larger quantities of higher‐potency LV is expected. However, primary capture by anion‐exchange chromatography (AIEX) remains a major manufacturing bottleneck from use of adsorbents not tailored to LVs, leading to ...

Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...
