Feedback on Escape Behavior of Birds Under Different Hunger Pressure.

The risk of predation has always been a significant impact on wild birds. Birds, facing with limited energy, must balance their investment between foraging and vigilance. There were currently limited understandings of the vigilant behavior feedback of birds under different hunger pressure.

Exploring Singlet Carbyne Anions and Related Low-Valent Carbon Species Utilizing a Cyclic Phosphino Substituent.

ConspectusThe advancement of synthetic methodologies is fundamentally driven by a deeper understanding of the structure-reactivity relationships of reactive key intermediates. Carbyne anions are compounds featuring a monovalent anionic carbon possessing four nonbonding valence electrons, which were historically confined to theoretical constructs or observed solely within the environment of gas-phase studies. These species possess potential for applications across diverse domains of synthetic chemistry and ancillary fields.

Anti-TMV activity based flavonol derivatives containing piperazine sulfonyl: Design, synthesis and mechanism study.

A series of flavonoid derivatives containing piperazine sulfonate were designed and synthesized. The results of antiviral experiments in vivo showed that some target compounds had good inhibitory effect on tobacco mosaic virus (TMV). The EC values of S15 and S19 curative activity were 174.

Threshold effects of sleep duration and cognitive function in older adults with BMI ≥ 25 kg/m.

Background: It has been demonstrated that older adults' cognitive capacities can be improved with sleep duration. However, the relationship between overweight, obesity, and cognitive decline remains a subject of debate. The impact of sleep duration on cognitive performance in seniors with a body mass index (BMI) ≥ 25 kg/m is largely unknown.

Deciphering the Genetic Basis of Sugar Cane ( L) Root System and Related Traits under Nitrogen Stress through the Integration of Genome-Wide Association Studies and RNA-seq.

Nitrogen (N) is an essential element for plant growth and development. Identifying functional gene loci associated with nitrogen absorption and utilization in sugar cane can facilitate the development of nutrient-efficient sugar cane varieties. In this study, sugar cane seedlings were subjected to normal and low nitrogen stress treatments within a hydroponic system for the identification of candidate genes related to six root-associated traits using a diversity population of 297 accessions.
