Polyamines as olfactory stimuli in goldfish [PDF]

open access: yes, 2002
The effects of polyamines as odorants to goldfish olfactory receptors were investigated by in vivo electrophysiological recordings. Electro-olfactogram (EOG) recordings indicated that polyamines (putrescine, cadaverine and spermine) are potent olfactory ...

Research progress on the microbial metabolism and transport of polyamines and their roles in animal gut homeostasis

open access: yesJournal of Animal Science and Biotechnology
Polyamines (putrescine, spermidine, and spermine) are aliphatic compounds ubiquitous in prokaryotes and eukaryotes. Positively charged polyamines bind to negatively charged macromolecules, such as nucleic acids and acidic phospholipids, and are involved ...

Hyperbranched poly‐L‐lysine surface‐engineered bioprosthetic heart valves with anti‐calcification, anti‐infection, and durability

open access: yesBMEMat, EarlyView.
The challenges of bioprosthetic heart valves (BHV) with respect to calcification, infection, and poor durability are tackled by surface engineering of hyperbranched poly‐L‐lysine (HBPL), providing a translational solution to improve long‐term valve performance.

Senescence and programmed cell death in plants: polyamine action mediated by transglutaminase

open access: yesFrontiers in Plant Science, 2014
Research on polyamines in plants laps a long way of about 50 years and many roles have been discovered for these aliphatic cations. Polyamines regulate cell division, differentiation, organogenesis, reproduction, dormancy-break and senescence ...

Porous Carbon Materials for Carbon Dioxide Capture

open access: yesCarbon Energy, EarlyView.
This work aims to address the current status and challenges associated with the regulation of pore structures, as well as the influence of pore structures on CO2 capture. Systematic quantitative analysis of structure–property relationships, combined with machine learning approaches, can effectively evaluate the contributions of structural ...
