Foliar Water Uptake Supports Water Potential Recovery but Does Not Affect Xylem Sap Composition in Two Salt-Secreting Mangroves.

Mangroves are highly salt-tolerant species, which live in saline intertidal environments, but rely on alternative, less saline water to maintain hydraulic integrity and plant productivity. Foliar water uptake (FWU) is thought to assist in hydration of mangroves, particularly during periods of acute water deficit. We investigated the dynamics of FWU in Avicennia marina and Aegiceras corniculatum by submerging and spraying excised branches and measuring leaf water potential (Ψ) at different time intervals.

"Inverse" shape memory effect in energetic electron crosslinked methylcellulose hydrogels: Programming, demonstration and quantification.

Shape memory hydrogels constitute a highly attractive materials class that bears enormous potential within a broad range of areas - from engineering to medicine. Within the present contribution we demonstrate that energetic electron crosslinked methylcellulose-only hydrogels exhibit an "inverse" shape memory effect that transforms from a secondary shape to its primary shape upon cooling. The primary shape can conveniently be "programmed" by application of energetic electrons.

New insights into a sensitive life stage: hydraulics of tree seedlings in their first growing season.

The first year in a tree's life is characterized by distinct morphological changes, requiring constant adjustments of the hydraulic system. Despite their importance for the natural regeneration of forests and future vegetation composition, little has been known about the hydraulics of tree seedlings. At different times across the first growing season, we analysed xylem area-specific (K) and leaf area-specific (K) shoot hydraulic conductance, as well as embolism resistance of three temperate conifer trees, two angiosperm trees and one angiosperm shrub, and related findings to cell osmotic parameters and xylem anatomical traits.

cPMP rescue of a neonate with severe molybdenum cofactor deficiency after serendipitous early diagnosis, and characterisation of a novel MOCS1 variant.

We report the first, and so far, only index patient with neonatal onset MoCD type A who was diagnosed and treated early enough with cPMP to avoid severe brain injury and disability. The child presented with hypoglycemia at the age of 10 h and was diagnosed because of the incidental finding of severely decreased L-cystine in plasma. Due to a high level of awareness and excellent co-operation between metabolic laboratory and clinical services, cPMP substitution could be initiated before severe encephalopathy set in, and the child subsequently had a normal motor development.
