Loop pathways are responsible for tuning the accumulation of C19- and C22-sterol intermediates in the mycobacterial phytosterol degradation pathway

open access: yesMicrobial Cell Factories, 2023
4-Androstene-3,17-dione (4-AD) and 22-hydroxy-23,24-bisnorchol-4-ene-3-one (BA) are the most important and representative C19- and C22-steroidal materials.

The Boolean algebra of Galois algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
Let B be a Galois algebra with Galois group G, Jg={b∈B|bx=g(x)b for all x∈B} for each g∈G, and BJg=Beg for a central idempotent eg, Ba the Boolean algebra generated by {0,eg|g∈G}, e a nonzero element in Ba, and He={g∈G|eeg=e}.

Ocular and Systemic Pharmacokinetics of Baicalein and Baicalin After Intravitreal Injection and Oral Administration in Mice

open access: yesPharmaceutics
Background: Glaucoma requires therapies that extend beyond intraocular pressure (IOP)-lowering strategies, and baicalein (BA) offers dual IOP-lowering and neuroprotective potential. This study evaluated the pharmacokinetics of BA and its major metabolite

The Boolean algebra and central Galois algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
Let B be a Galois algebra with Galois group G, Jg={b∈B∣bx=g(x)b   for all   x∈B} for g∈G, and BJg=Beg for a central idempotent eg. Then a relation is given between the set of elements in the Boolean algebra (Ba,≤) generated by {0,eg∣g∈G} and a set of ...

Effect of Ba and Mg as promoter on Ru/g-C3N4 catalyst for CO2 methanation

open access: yesJournal of CO2 Utilization
Catalytic hydrogenation of CO₂ to produce value-added hydrocarbons is a promising strategy for reducing greenhouse gas emissions and producing renewable fuels and chemicals. In this study, Ru- g-C₃N₄ catalysts were modified with barium (Ba) and magnesium
