Greater Glycaemic Responses to Bodyweight Change in South Asians Than White Europeans at High Risk of Type 2 Diabetes

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Bodyweight change is an important determinant of cardiometabolic health, but its metabolic impact may differ by ethnicity. This study investigated whether ethnicity (White European, South Asian) modifies the association between change in bodyweight and changes in HbA1c and oral glucose tolerance test (OGTT)–derived measures.

Transfer of zinc from xylem to phloem in the peduncle of wheat

, 1994
Maturing wheat grains represent major sinks for solutes in the phloem, while the xylem sap entering the ear is mainly delivered td the glumes. Nutrients and assimilates transported in the phloem may either be exported from source organs or loaded into ...

Living on the edge – physiological tolerance to frost and drought explains range limits of 35 European tree species

Ecography, EarlyView.
Species distribution models are key to evaluate how climate change threatens European forests and tree species distributions. However, current models struggle to integrate ecophysiological processes. Mechanistic models are complex and have high parameter requirements.

Weak tradeoff between xylem safety and xylem­specific hydraulic efficiency across the world’s woody plant species

, 2016
The evolution of lignified xylem allowed for the efficient transport of water under tension, but also exposed the vascular network to the risk of gas emboli and the spread of gas between xylem conduits, thus impeding sap transport to the leaves.

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

Ecological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

Insect Molecular Biology, EarlyView.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...

Protein extraction from xylem and phloem sap

, 2007
It is well known that phloem and xylem vessels transport small nutrient molecules over long distances in higher plants. The finding that proteins also occur in both transport fluids was unexpected, and the function of most of these proteins is not yet ...

Development of an Artificial Liquid Diet for Allelochemical Delivery in Lycorma delicatula

Journal of Applied Entomology, EarlyView.
ABSTRACT Spotted lanternfly, Lycorma delicatula White (Hemiptera: Fulgoridae), is an invasive phloem‐feeding planthopper native to Asia, which poses a growing threat to US agriculture due to its broad host range and rapid spread since its 2014 detection. To better understand how L.

A numerical model of coupled phloem-xylem flows for dynamic long-distance transport in trees

In trees, the vascular system is dual in structure and func)on. Sap flows upwards in the xylem to hydrate )ssues and refill reserves from transpira)on loss.

First Strike: Description of the Events at the First Salmon Farm Affected by the 2025 Algal Bloom in Northern Norway

Journal of Fish Diseases, EarlyView.
ABSTRACT Harmful algal blooms (HABs) are a threat to fish welfare, occurring suddenly and unexpectedly causing significant consequences for fish and salmon farmers worldwide. Norwegian farmers have been facing this challenge at irregular intervals since the very beginning of the industry. This report describes the events on the first fish farm affected
