In this work, a new surface plasmon resonance (SPR) sensor based on sulphur-doped titanium dioxide (S-TiO) nanostructures and molecularly imprinted polymer (MIP) was presented for thiram (THI) determination in milk samples. Firstly, the S-TiO nanomaterial with a high product yield was prepared by using a facile sol-gel hydrolysis technique with a high product yield. After that, UV polymerization was carried out for the preparation of the THI-imprinted SPR chip based on S-TiO using a mixture including ethylene glycol dimethacrylate (EGDMA) as the cross-linker, N,N'-azobisisobutyronitrile (AIBN) as the initiator, and methacryloylamidoglutamicacid (MAGA) as the monomer.

- The study aimed to explore the protective effects of red dragon fruit extract (DFE) on gastric ulcers induced by indomethacin in rats, focusing on changes in oxidative stress markers and histopathological findings.
- After treating the rats with DFE and inducing ulcers with indomethacin, the researchers noted significant improvements in oxidative stress levels in the groups that received DFE, particularly at higher doses of 500 mg/kg and 1000 mg/kg.
- The findings suggest that DFE may mitigate gastric damage by lowering harmful markers like MDA and Caspase 3, while enhancing antioxidant levels, indicating a potential natural remedy for those suffering from gastric ulcers caused by NSAID use.
