Proteo‐transcriptomic insights into the venom composition of the ectoparasitoid Eupelmus urozonus

Pest Management Science, EarlyView.
Integrated venom‐gland transcriptomics and venom proteomics of Eupelmus urozonus identified 316 venom proteins, including 75 secreted candidates, revealing diverse hydrolases, proteases/inhibitors and many uncharacterized effectors. Abstract BACKGROUND Ectoparasitoid venoms are ‘cocktails’ of bioactive molecules injected during oviposition to paralyze ...

Localization of Spermidine Uptake in Rabbit Lung Slices

, 1989
The lungs have a high polyamine transport capability, and the type II pneumocyte has recently been identified as a major site of putrescine uptake and localization (N.A. Saunders, P.J. Rigby, K. F. Ilett, and R.F. Minchin. Lab. Invest. 59: 380-386, 1988).

Efficient water‐soluble blue/red‐emissive carbon dots matching plant absorption spectra: Synthesis, tunable control, and their applications in promoting plant growth

Responsive Materials, EarlyView.
Guided by the spectral demand of plant photosystems, this review summarizes the synthesis, emission regulation, dual‐emission design, and gram‐scale production of CDs for agricultural applications. Spectrally matched blue‐ and red‐emissive CDs enhance plant light utilization by converting underutilized light into photosynthetically active radiation and

Dimethylthiourea, a hydrogen peroxidase trap, partially prevents stress effects and ascorbate peroxidase increase in spermidine-treated maize roots

, 2001
Inhibition of root growth and accumulation of putrescine caused by exogenous spermidine in roots of maize seedlings (Zea mays L., cv Samodek) were partially prevented by a concomitant treatment with dimethylthiourea (DMTU), that traps H2O2 produced from ...

Predicted microbiome‐associated metabolic pathways are linked to immune checkpoint modulation in chronic lymphocytic leukaemia

British Journal of Haematology, EarlyView.
Summary Microbial metabolites are key regulators of host immunity, yet their functional impact in chronic lymphocytic leukaemia (CLL) remains unclear. Following up on our earlier observations of microbiome dysbiosis in CLL, we performed predictive metabolic profiling based on 16S ribosomal RNA (rRNA) sequencing of oral and stool samples collected from ...
