The low KM-phosphodiesterase inhibitor denbufylline enhances neuronal excitability in guinea pig hippocampus in vitro [PDF]

open access: yes, 1990
The actions of the phosphodiesterase inhibitor denbufylline on the excitability of hippocampal neurons were investigated by means of extracellular and intracellular recordings.

From apex to base: Uncovering spatial metabolic adaptation in Antarctic mosses

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Antarctic mosses survive extreme cold, desiccation, UV exposure, and oxidative stress. We analyzed three species by separating apical, middle, and basal zones. Each zone showed distinct metabolite patterns and biological roles, revealing spatial metabolic specialization. The results suggest that whole‐plant survival depends on coordinated contributions

Involvement of adenosine 3':5'-cyclic monophosphate in the yeast-mycelium transition of Aureobasidium pullulans

open access: yes, 1985
The yeast-mycelium transition of Aureobasidium pullulans (IMI 45533) was induced by adenosine and adenosine 5'-monophosphate (AMP) in defined liquid medium. During the yeast-mycelium transition uptake of adenosine or AMP and transformation to adenosine 3'

cAMP Accumulation Assays Using the AlphaScreen® Kit (PerkinElmer)

open access: yesBio-Protocol, 2013
Cyclic adenosine monophosphate (cAMP) is an intracellular signaling messenger derived from the catalytic conversion of ATP, and is a major product of activated Gs protein-coupled receptors. Conversely, formation of cAMP is inhibited by Gi protein-coupled

An all‐in‐one fucosylated gold nanocluster probe enables NIR‐II imaging and multi‐mechanistic therapy of acute kidney injury

open access: yesBMEMat, EarlyView.
This study developed a fucoside‐targeted gold nanocluster probe that enables early NIR‐II imaging and multi‐mechanistic therapy for acute kidney injury, effectively mitigating oxidative stress, modulating inflammatory responses, and inhibiting ferroptosis to improve renal outcomes. Abstract Acute kidney injury (AKI) remains a life‐threatening condition
