Wine Putrescine Abatement by Bentonites: From Ideal Case to Practice [PDF]
, 2023 Herein, we demonstrated that bentonites can be incisively used to reduce wine BAs content, especially putrescine molecules. Pioneering kinetic and thermodynamic studies of putrescine adsorption onto two commercially available bentonites (optimal ...

The Smell of Death: Evidence that Putrescine Elicits Threat Management Mechanisms
Frontiers in Psychology, 2015 The ability to detect and respond to chemosensory threat cues in the environment plays a vital role in survival across species. However, little is known about which chemical compounds can act as olfactory threat signals in humans.

Advanced Science, EarlyView.Here we developed Am@SExo, a dual‐functional engineered exosome that coordinates CD47–SIRPα checkpoint blockade with Arg1 mRNA–mediated metabolic reprogramming. Surface SIRPα promotes recognition of apoptotic cells and plaque targeting, while Arg1 expression enhances arginine–ornithine metabolism, Rac1 activation, and actin remodeling in macrophages ...

Effect of mycorrhizal fungi and foliar application of putrescine on some biochemical characteristics and biomass of basil (Ocimum ciliatum L.) in two different harvesting times [PDF]
فیزیولوژی محیطی گیاهی, 2019 In order to investigate the effect of mycorrhizal fungi and foliar application of putrescine on some biochemical characteristics, essential oil content, and biomass of basil (Ocimumciliatum L.), a split plot in time experiment with three replications was

Advanced Science, EarlyView.A non‐invasive periodontitis diagnosis platform was developed using Au nanoparticles‐decorated mesoporous Cr2O3 (Au@mCr2O3) particles with Schwarz P surface as matrix for saliva metabolic fingerprinting (SMFs) analysis via MALDI‐MS. With the assistance of machine learning of SMFs, this platform enables efficient diagnosis and the screening of potential

A Synthetic Biosensor for Detecting Putrescine in Beef Samples [PDF]
, 2022 Biogenic amines (BAs) are toxicological risks present in many food products. Putrescine is the most common foodborne BA and is frequently used as a quality control marker. Currently, there is a lack of regulation concerning safe putrescine limits in food

Enzymic conversion of agmatine to putrescine in Lathyrus sativus seedlings. Purification and properties of a multifunctional enzyme (Putrescine synthase) [PDF]
, 1981 The participation of a multifunctional enzyme (a single polypeptide with multiple catalytic activities (14)) has been demonstrated in the conversion of agmatine to putrescine in Lathyrus sativus seedlings.
