MAGHEMITE PARTICLES FOR SPERMIDINE SEPARATION [PDF]

open access: yesNANOCON Conference Proeedings, 2020
We report the optimal conditions for the separation of spermidine from different types of samples, for example blood or cancer cells and its subsequent determination by ion-exchange liquid chromatography (IEC) with UV-VIS detector. Here in, we synthesized paramagnetic particles able to isolate and immobilize spermidine from blood of patients with ...

Compartmentation of spermidine in Neurospora crassa. [PDF]

open access: yes, 1983
The polyamines putrescine, spermidine, and spermine are multivalent cations that bind to anionic cell constituents such as nucleic acids. Their distribution between free and bound states within the cell is not known.

SPERMIDINE MAINTAINS TELOMERE LENGTH AND DELAYS AGING

open access: yesCentral Asian Journal of Medical Hypotheses and Ethics, 2021
Spermidine, a natural polyamine, has been noticed for its anti-aging properties. Supplementation of this drug prolongs lifespan and diminishes the incidence of age-related pathology. In the human population, spermidine levels decrease as aging progresses,

Role of Spermidine in Overwintering of Cyanobacteria [PDF]

open access: yesJournal of Bacteriology, 2015
ABSTRACT Polyamines are found in all groups of cyanobacteria, but their role in environmental adaptation has been barely investigated. In Synechocystis sp. strain PCC 6803, inactivation of spermidine synthesis genes significantly reduced the survivability under chill (5°C)-light stress, and the ...

Spermidine feeding decreases age-related locomotor activity loss and induces changes in lipid composition

open access: yes, 2014
Spermidine is a natural polyamine involved in many important cellular functions, whose supplementation in food or water increases life span and stress resistance in several model organisms.

Engineered spermidine-secreting Saccharomyces boulardii enhances olfactory memory in Drosophila melanogaster

open access: yesFrontiers in Neuroscience
IntroductionThe polyamines putrescine, spermidine, and spermine are ubiquitous metabolites synthesized in all cells. The intracellular levels of polyamines, especially spermidine, decrease in aging.

Spermidine as a target for cancer therapy

open access: yesPharmacological Research, 2020
Spermidine, as a natural component from polyamine members, is originally isolated from semen and also existed in many natural plants, and can be responsible for cell growth and development in eukaryotes. The supplementation of spermidine can extend health and lifespan across species. Although the elevated levels of polyamines and the regulation of rate-

Spermidine-Induced Attraction of Like-Charged Surfaces Is Correlated with the pH-Dependent Spermidine Charge: Force Spectroscopy Characterization

open access: yes, 2018
The ubiquitous molecule spermidine is known for its pivotal roles in the contact mediation, fusion, and reorganization of biological membranes and DNA. In our model system, borosilicate beads were attached to atomic force microscopy cantilevers and used ...

Spermidine-induced hypusination preserves mitochondrial and cognitive function during aging [PDF]

open access: yes, 2021
Spermidine is a natural polyamine, central to cellular homeostasis and growth, that promotes macroautophagy/autophagy. The polyamine pathway is highly conserved from bacteria to mammals and spermidine (prominently found in some kinds of aged cheese ...
