Objective: Hepatic ischemia reperfusion (I/R) injury is regarded as a serious concern in clinical practice. Citric acid reduces oxidative stress and inflammation during hypoxia and reoxygenation. Our objective was to investigate the protective effect of citric acid against hepatic I/R injury in rats.
Methods: We fed Sprague-Dawley rats either citric acid (100 mg/kg/d) or saline. One week later, ischemia was induced by clamping the rats' common hepatic artery and portal vein for 30 minutes. The rats were randomly divided into 3 major groups that were treated as follows: 1. the sham operated group; 2. the I/R group; and 3. the I/R-citric acid group.
Results: Compared to the sham group, the I/R group had higher expression of aspartate aminotransferase and alanine aminotransferase and lower expression of catalase, superoxide dismutase, glutathione peroxidase, antioxidant, nitric oxide, and albumin. Compared to the I/R group, the I/R-citric acid group had higher expression of catalase, superoxide dismutase, antioxidants, and nitric oxide, and lower expression of aspartate aminotransferase and alanine aminotransferase.
Conclusions: These results suggest that citric acid therapy has significant therapeutic potential in ischemic liver injury.

Several approaches for synthesizing [1-C]2-oxoglutaric acid were attempted, and the synthesis was successfully achieved in 4 steps from trimethylsilyl C-cyanide. The C-breath tests on rats were conducted by orally administering the newly synthesized [1-C]2-oxoglutaric acid, the previously prepared [1'-C]citric acid, and [1-C]acetic acid as a control drug, and the results were compared. The results indicate that [1-C]2-oxoglutaric acid and [1'-C]citric acid may serve as potential substrates for assessing the TCA cycle flux.

Efficient water-absorbing and water-holding materials have shown notable promise in various applications, including hygiene products, agriculture, and drug delivery systems. Opposed to traditional absorbents prepared using synthetic polymers, bio-based, environmentally friendly efficient absorbents have attracted more attention from both academia and the industry. Herein, the aerogel absorbents from functional sodium carboxymethyl cellulose (CMCNa), citric acid (CA) crosslinker, and cellulose nanofibers (CNF) have been developed via freeze-drying and cross-linking process.

Background: Despite the advancements of pharmacological treatments and gauze dressings in the field of skin wound healing, these methods present numerous limitations. Therefore, developing a multifunctional material capable of efficiently promoting skin wound healing is particularly crucial.
Methods: Citric acid (CA)-modified chitosan (CS) loaded with Shikonin (SK) (CA-CS-SK) hydrogel was prepared via the freeze-thaw method.

In recent years, there has been a rapid increase in the incidence of thyroid carcinoma (TC). Our study focuses on the regulatory effect of circular RNAs on metabolism of TC, aiming to provide new insights into the mechanisms of progression and a potential therapeutic target for TC. In this study, we identified high expression levels of circPSD3 in TC tissues through RNA sequencing.
