The Effect of Ligand Reactivity and Carrier Mechanics on Thiol‐Mediated Cellular Uptake for miRNA Nano‐Drugs

open access: yesAdvanced Science, EarlyView.
The effect of ligand reactivity and carrier mechanics on thiol‐mediated uptake was investigated at the single‐molecule/particle level. The interaction kinetics of LA and AspA with membrane thiols were quantified; AspA is more efficient due to the higher binding affinity, greater binding stability, and more double‐disulfide binding, as well as greater ...

Limitation of Bacteria by Micro-Predators in Soil

open access: yes, 1948
EIGHTY-SEVEN strains of very varied bacteria, comprising common and rare strains from soil, pigmented and non-pigmented ‘‘miscellaneous strains, and a number of plant pathogens, were tested on eight micro-predators belonging to four different groups ...

Phase Separation of SF3B1 Serves as a Critical Post‐Transcriptional Regulator During Early Mouse Embryogenesis

open access: yesAdvanced Science, EarlyView.
Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...

Estimating predation of the grain aphid Sitobion avenae by polyphagous predators

open access: yes, 1994
1. The numbers of dead and live aphids falling to the ground in a cereal crop were estimated. The estimates showed that more live aphids fall to the ground than dead ones. 2. The availability of live aphids to predators which forage on the ground was low

Enhanced Endophytic Colonization of Flavobacterium Promotes Plant Resistance to Fusarium Wilt

open access: yesAdvanced Science, EarlyView.
A natural microbial consortium employing a cross‐feeding strategy forms a stratified biofilm that promotes endophytic colonization of auxotrophic Flavobacterium. This enhanced colonization activates plant systemic resistance, effectively suppressing Fusarium wilt.

Cereal aphids (Hemiptera: Aphidoidea) in Serbia: Seasonal dynamics and natural enemies

open access: yesEuropean Journal of Entomology, 2008
During 1989-2006 the number of live aphid, mummies, aphid specialist predators and their parasitoids in cereal fields in Serbia were recorded. S. avenae and M. dirhodum were the most common, both on wheat and rye crops.

Aphidophagy among polyphagous predators [PDF]

open access: yes, 2020
Aphids are among the most widespread insect pests in agroecosystems. So far, significant attention has been paid to their natural enemies, especially to specialized predators and parasitoids.
