Chronic Stress Promotes Gastric Cancer Metastasis by Inducing Microbiota‐Associated Kynurenine Accumulation and Macrophage Remodeling

Advanced Science, EarlyView.
Chronic stress reshapes the gut microbiota and enriches Lactobacillus reuteri, promoting microbiota‐associated kynurenine accumulation through altered tryptophan metabolism. Kynurenine drives immunosuppressive remodeling of tumor‐associated macrophages through TNFR2–C/EBPβ signaling, thereby enhancing gastric cancer dissemination.

The liver‐brain axis: A multidimensional regulatory network implicated in Alzheimer's disease pathogenesis and clinical implications

Animal Models and Experimental Medicine, EarlyView.
Schematic diagram of the core pathways of the liver‐brain axis in regulating AD. The liver regulates cerebral Aβ deposition, tau phosphorylation, and neuroinflammation through pathways such as metabolic detoxification (urea cycle, ketone body metabolism, glutathione antioxidant system), molecular secretion (APOE, CRP, FGF21, IGF‐1), and Aβ clearance ...

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Delayed Increases in Regional Brain Quinolinic Acid Follow Transient Ischemia in the Gerbil

, 1990
Excessive activity or release of excitatory amino acids has been implicated in the neuronal injury that follows transient cerebral ischemia. To investigate the metabolism of the endogenous excitotoxin, quinolinic acid, and its potential for mediating ...

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Effect of animal and industrial trans fatty acids on HDL and LDL cholesterol levels in humans - a quantitative review [PDF]

, 2010
Background: Trans fatty acids are produced either by industrial hydrogenation or by biohydrogenation in the rumens of cows and sheep. Industrial trans fatty acids lower HDL cholesterol, raise LDL cholesterol, and increase the risk of coronary heart ...

Ketogenic diet for infantile epileptic spasms

Epilepsia Open, EarlyView.
Abstract Approximately half of all cases of Infantile Epileptic Spasms Syndrome (IESS) do not respond to vigabatrin and hormonal therapies. There is no clear consensus as to the second‐line therapy for IESS. Ketogenic diet (KD) has emerged as an effective treatment for certain drug‐resistant epilepsies and in many cases of IESS.
