Objectives: CC-chemokines and kynurenine pathway (KP) metabolites are associated with accelerated atherosclerosis in chronic kidney disease (CKD) patients.
Design And Methods: We evaluate the plasma levels of anthranilic acid (AA), 3-hydroxyanthranilic acid (3-HAA) and their possible relationship with CC-chemokines, Cu/Zn superoxide dismutase (Cu/Zn SOD) as the marker of oxidative status and high sensitivity C-reactive protein (hsCRP) as an index of inflammation in the population of 48 CKD patients.
Results: Compared with controls, CKD patients showed a significant increase in plasma concentrations of CCL2, CCL4, AA, 3-HAA, Cu/Zn SOD and hsCRP. Multiple stepwise regression analysis identified inflammation, renal function and 3-HAA levels as the independent variables significantly associated with increased CCL2; whereas age, 3-HAA and renal function as independent variables associated with CCL4.
Conclusions: These results suggest a relationship between CC-chemokine system and KP activation, which may represent one of the mechanisms involved in the accelerated atherosclerosis in CKD population.

Introduction: Transcutaneous auricular vagus nerve stimulation (taVNS) is a promising therapy for irritable bowel syndrome (IBS). This clinical trial aims to evaluate the influence of taVNS on autonomic functions, rectal sensation, and acetylcholine (Ach) levels and to explore potential mechanisms involving gut microbiota and metabolic profiles.
Methods: This study was a single-center, single-blind, randomized controlled trial executed at the First Affiliated Hospital of USTC, Anhui, China.

Background: Gastric cancer (GC) is among the most malignant tumors, with the lowest five-year survival rate, and limited treatment options. Kynureninase (KYNU), is a key molecule in tryptophan metabolism and promotes tumor progression and immunosuppression. Cuproptosis is a non-apoptotic cell death mechanism, primarily due to oxidative stress caused by copper ion accumulation, that is related to tumor progression and drug resistance.

Aims: Chronic hypobaric hypoxia frequently results in memory deficits, with severe cases showing marked alterations in dopamine levels and its metabolites. This research explores caffeine's modulation of the adenosine AA receptor (AAR) and its regulatory effects on tyrosine hydroxylase (TH), aiming to restore dopamine homeostasis and mitigate memory impairments associated with hypoxia. The goal is to identify novel preventive strategies against cognitive decline induced by hypoxia.
