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

open access: yesIrrigation 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 ...

Lysosomal Expression Profile in Plasma Associates with Disease Severity in Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is a clinically and biologically heterogeneous neurodegenerative disorder, driven by multiple mechanisms among which are lysosomal and mitochondrial dysfunction. Here, we explored blood‐based lysosomal and mitochondrial profiles in relation to PD diagnosis and severity.

AI‐Driven Rational Design of Nanotherapeutics for Pancreatic Ductal Adenocarcinoma

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Pancreatic ductal adenocarcinoma (PDAC) remains a formidable malignancy characterized by late diagnosis, high recurrence rates, and pronounced chemoresistance. While nanoparticle‐based drug delivery systems (NDDS) offer theoretical advantages over conventional therapies, their clinical translation in PDAC has been severely limited.
