Uric acid in urine was analyzed using porcine liver uricase and horseradish peroxidase immobilized on alkylamine and arylamine glass beads (pore diameter 55nm) respectively. The minimum detection limit was 5.0mg/0.1 ml urine. The recovery of added uric acid was 92%. Within and between assay CVS were <1.3% and <5.3% respectively. A good correlation (r=0.93) was found between urinary urate values obtained by a commercial kit method and the present method. The uric acid in 24hr urine of apparently healthy adults and person sufering from various diseases was found to be 450 to 900mg/24hr, 659mg/24hr (range, mean) and 910-1400mg/24hr, 1145 mg/24hr (range, mean) respectively with the present method.

A smartphone-based non-invasive method was developed for salivary uric acid detection using Gleditsia Sinensis carbon dots (GS-CDs). The GS-CDs synthesized by the one-pot hydrothermal method emitted blue fluorescence at a maximum excitation wavelength of 350 nm and had good fluorescence stability in the presence of different ions, while showing selectivity to uric acid solution. The ability of uric acid (UA) to quench the fluorescent substances present in the GS-CDs, was confirmed through HPLC-FLD and LC-MS, FTIR and XPS.

Background: Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are known for their cardiovascular benefits, but their impact on serum uric acid levels is not well understood. This study evaluates the hypouricemic effects of SGLT2is and their potential cardiovascular implications.
Methods: A network meta-analysis was performed, including 56 studies (16,788 participants) contributing data to the meta-analysis.
The Association of Persistent Hyperuricemia With Liver Function and the Management of Uric Acid Levels: Insights From a Three-Year Prospective Cohort Study.

Department of Rheumatology, The Third Affiliated Hospital of Sun Yat-Sen University, Guangzhou, Guangdong Province, China.
Objective: The association of long-term hyperuricemia with liver function remains less well understood. This prospective cohort study aimed to investigate the relationship between hyperuricemia and liver function as well as other metabolic and cardiovascular parameters.
Methods: We enrolled 375 participants with hyperuricemia and 599 normouricemic controls.
Evaluation of the Therapeutic Potential of the Methanolic Extract and Fractions of Datura stramonium in Paracetamol-intoxicated Rabbits.

Department of Horticulture and Life Science, Yeungnam University, Republic of Korea.
Introduction: Datura stramonium (DS) possesses strong medicinal and therapeutic potential but has been rarely evaluated in this context.
Methods: The present study was intended to evaluate the antioxidant, hepatoprotective, and nephroprotective potential of the crude methanolic leaf extract and ethyl acetate, chloroform, n-hexane, and aqueous fractions of DS in paracetamol-intoxicated rabbits. Paracetamol (2 g/Kg BW) was applied to induce liver and kidney injury in rabbits while the methanolic extract and fractions of DS were applied in the dose range of 150 mg/Kg to 300 mg/Kg body weight for 21 days.

Background: Post-traumatic cerebral infarction (PTCI) is a severe complication resulting from traumatic brain injury (TBI), which can lead to permanent neurological damage or death. The investigation of the factors associated with PTCI and the establishment of predictive models are crucial for clinical practice.
Methods: We made a retrospective analysis of clinical data from 1484 TBI patients admitted to the Neurosurgery Department of a provincial hospital from January 2018 to December 2023.
