Long-term trends of changes in pine and oak foliar nitrogen metabolism in response to chronic nitrogen amendments at Harvard Forest, MA [PDF]
, 2015 We evaluated the long-term (1995–2008) trends in foliar and sapwood metabolism, soil solution chemistry and tree mortality rates in response to chronic nitrogen (N) additions to pine and hardwood stands at the Harvard Forest Long Term Ecological Research

MAGHEMITE PARTICLES FOR SPERMIDINE SEPARATION [PDF]
NANOCON 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 ...

New Insights into the Roles and Mechanisms of Spermidine in Aging and Age-Related Diseases
Aging and Disease, 2021 High incidences of morbidity and mortality associated with age-related diseases among the elderly population are a socio-economic challenge. Aging is an irreversible and inevitable process that is a risk factor for pathological progression of diverse age-

Lactobacillus reuteri ZJ617 attenuates metabolic syndrome via microbiota-derived spermidine
Nature CommunicationsMetabolic syndrome (MetS) is a difficult-to-manage disease that poses a significant risk to human health. Here, we show that the supplementation of Lactobacillus reuteri ZJ617 ameliorates symptoms of MetS in mice induced by the high-fat diet. L.

Spermidine-induced hypusination preserves mitochondrial and cognitive function during aging
Autophagy, 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 ...

SPERMIDINE MAINTAINS TELOMERE LENGTH AND DELAYS AGING
Central 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,

Spermidine and spermine delay brain aging by inducing autophagy in SAMP8 mice
Aging, 2020 The natural polyamine spermidine and spermine have been reported to ameliorate aging and aging-induced dementia. However, the mechanism is still confused. An aging model, the senescence accelerated mouse-8 (SAMP8), was used in this study.
