Polyamines under Abiotic Stress: Metabolic Crossroads and Hormonal Crosstalks in Plants

Metabolites, 2012
Polyamines are essential compounds for cell survival and have key roles in plant stress protection. Current evidence points to the occurrence of intricate cross-talks between polyamines, stress hormones and other metabolic pathways required for their ...

Evidence that host size determines liver size: Studies in dogs receiving orthotopic liver transplants [PDF]

, 1987
Orthotopic liver transplantation was performed in two groups of dogs; Group I animals consisted of large dogs that served as recipients of livers obtained from smaller dogs while Group II animals consisted of dogs that received liver from donor dogs of ...

Competition between condensation of monovalent and multivalent ions in DNA aggregation

, 2004
We discuss the distribution of ions around highly charged PEs when there is competition between monovalent and multivalent ions, pointing out that in this case the number of condensed ions is sensitive to short-range interactions, salt, and model ...

A Supramolecular Nanoscavengers: Based “Cargo‐Exchange” Breaking Cholesterol Metabolic Dysregulation for Glioblastoma Therapy

Advanced Science, EarlyView.
Dysregulated cholesterol metabolism, driven by a complex array of mechanisms, is a defining characteristic of glioblastoma (GBM). In this study, supramolecular nanoscavengers are engineered by harnessing the intrinsic binding affinity between endogenous small‐molecule cholesterol and β‐cyclodextrin (β‐CD).

Utilizing Cooperative Proton–Electron Mixed Conduction Induced via Chemical Dedoping of Self‐Doped Poly(3,4‐ethylenedioxythiophene) Nanofilms for In‐Material Physical Reservoirs

Advanced Science, EarlyView.
This study demonstrates a new concept for high‐performance in‐material physical reservoirs (PRs). An intrinsic and cooperative ion–electron state, induced by chemical dedoping in self‐doped poly(3,4‐ethylenedioxythiophene) (S‐PEDOT) nanofilms, enhances the performance of in‐material PRs.

Dietary polyamines promote intestinal adaptation in an experimental model of short bowel syndrome

Scientific Reports
Intestinal adaptation does not necessarily recover absorptive capacity in short bowel syndrome (SBS), sometimes resulting in intestinal failure-associated liver disease (IFALD). Additionally, its therapeutic options remain limited. Polyamines (spermidine
