Spermidine Reproduces the Anti‐Inflammatory Effects of Intermittent Fasting and Prevents Urate and Calcium Pyrophosphate Crystal‐Induced Inflammation

Arthritis &Rheumatology, Volume 78, Issue 2, Page 449-462, February 2026.
Objective Gout caused by the formation of monosodium urate (MSU) crystals and calcium pyrophosphate (CPP) deposition disease are two major types of microcrystalline pathologies in adults. They are responsible for recurrent flares that rely on interleukin (IL) 1β via activation of the NLRP3 inflammasome.

Impact of nitric oxide on proline and putrescine biosynthesisin Chlamydomonas via transcriptional regulation

Biologia Plantarum, 2020
Nitric oxide plays an important role in regulating adaption of the model alga Chlamydomonas reinhardtii to various environmental stresses. One response to abiotic stresses is the accumulation of protective molecules such as proline and putrescine. The NO

Effects of Extremely Low Frequency Magnetic Field Exposure (50 Hz, 200 µT) on Cell Viability, DNA Damage and Micronucleus Formation of Human Skin Cells

Bioelectromagnetics, Volume 47, Issue 2, February 2026.
ABSTRACT Both everyday electrical devices and high voltage transmission lines produce electric and magnetic fields with a frequency of 50 Hz in Europe and most other countries. Although several studies have already been investigating the effects of extremely low frequency magnetic field (ELF‐MF) exposure on biological material, this topic is still ...

Metabolite Profiling and Anticancer Evaluation of Iraqi Haloxylon articulatum Halophyte via LC–HRMS/MS, Molecular Docking, and ADMET Analysis

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
This study investigates the phytochemical composition and biological activities of a hydroalcoholic extract of Haloxylon articulatum. LC‐HRMS/MS identified diverse bioactive compounds, notably N‐caffeoyltyramine and sinapoyltyramine. The extract exhibited strong antioxidant activity and significant cytotoxic effects against gastric cancer cell lines ...

The Development of Polyamines throughout Brassica rapa over its Lifecycle [PDF]

, 2014
Polyamines are naturally produced chemicals in plants involved in growth, development and stress response. The primary objective of my study is to create a profile of changes in the entire life of the plant, in every organ at all stages of development ...

Ornithine decarboxylase and malignant growth

Bulletin of Experimental Biology and Medicine, 1993
There is indirect evidence that key enzymes which catalyse both synthesis and degradation of polyamines (PA) may be useful as biological markers of malignant growth. Ornithine decarboxylase (ODC) activity was assessed in fetal, regenerating and adult rat liver, in hepatoma with different growth rate, in Morris hepatoma cell lines and in rat liver in ...

Metabolic reprogramming of efferocytosis in the tumour microenvironment: From apoptotic‐cell clearance to therapeutic targeting

Clinical and Translational Medicine, Volume 16, Issue 2, February 2026.
This review systematically deconstructs the pathological efferocytic—metabolic axis in tumours, framing it as a three‐stage, self‐reinforcing cycle: from metabolite‐driven macrophage recruitment, through hijacked surface recognition, to post‐phagocytic metabolic reprogramming that locks in immunosuppression.

Molecular mechanisms of adaptation of the moderately halophilic bacterium Halobacillis halophilus to its environment [PDF]

, 2013
The capability of osmoadaptation is a prerequisite of organisms that live in an environment with changing salinities. Halobacillus halophilus is a moderately halophilic bacterium that grows between 0.4 and 3 M NaCl by accumulating both chloride and ...

Seasonal and Environmental Influences on Free Sugar and Amino Acid Profiles of Lycium barbarum Berries Cultivated in Southern Tuscany

Food Science &Nutrition, Volume 14, Issue 2, February 2026.
The graphical abstract illustrates how temperature, rainfall, and ripening stage shape the metabolic profile of Lycium barbarum berries grown in Southern Tuscany. It highlights the optimal harvest window (S2–S4) and summarizes key trends in sugars (glucose, fructose, pectins) and amino acids (total FAAs, proline, BABA, ornithine). Visual cues show that
