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

open access: yesResponsive 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

Distinct pathways for the absorption and metabolism of β-carotene and zeaxanthin in the mouse intestine

open access: yesJournal of Lipid Research
Carotenoids, essential nutrients for eye health, are absorbed in the intestine to support vitamin A homeostasis and provide cellular protection. This process involves the lipid transporters scavenger receptor class B type 1 (SR-B1, encoded by Scarb1 gene)

Protective Effects of Bee Venom (Apis mellifera) Against Cadmium‐Induced Hepatorenal Toxicity, Oxidative Stress, and Anxiety‐Like Behavior in Rats

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Cadmium (Cd) is a persistent environmental heavy metal and a major public health concern because it persists in the body for long periods and gradually accumulates in vital organs, particularly the liver, kidneys, and brain. Chronic Cd exposure promotes the excessive production of reactive oxygen species (ROS), which ultimately leads to ...

The organoalkali route to vitamin A and b-carotene

open access: yes
The reductive cleavage of Me vinyl-b-ionyl ether or the deprotonation of 3,2',6',6'-tetramethyl-5-(1-cyclohexenyl)-1,3-pentadiene gives rise to an organometallic C15 species that combines selectively with a variety of electrophiles at the terminal chain ...
