Article Title: κ-opioid receptor agonists may alleviate intestinal damage in cardiopulmonary bypass rats by inhibiting the NF-κB/HIF-1α pathway

doi: 10.3892/etm.2020.8685

Figure Lengend Snippet: KOR agonist inhibits inflammatory and oxidative stress responses in CPB model rats. (A) Inflammatory factors and (B) oxidative stress factors detected by ELISA. * P<0.05. CPB, cardiopulmonary bypass; KOR, κ-opioid receptor; K, KOR agonist (U50488H) + CPB; IL, interleukin; TNF-α, tumor necrosis factor-α; SOD, superoxidase dismutase; MDA, malondialdehyde; NO, nitric oxide.

Article Snippet: In addition, the oxidative stress indicators superoxidase dismutase (SOD; cat. no. SES134Hu), malondialdehyde (MDA; cat. no. CEA597Ge), nitric oxide (NO; cat. no. IS100) and the intestinal injury markers D-lactic acid in serum (cat. no. CEV643Ge), diamine oxidase (DAO; cat. no. SEJ298Hu) and intestinal fatty acid-binding protein (I-FABP; cat. no. SEA559Ra) were detected in the serum using kits from Wuhan USCN Business Co., Ltd.

Article Title: Curcumin nanoparticles alleviate brain mitochondrial dysfunction and cellular senescence in γ-irradiated rats

doi: 10.1038/s41598-025-87635-y

Figure Lengend Snippet: Effect of radiation and curcumin nanoparticles on brain levels of malondialdehyde (MDA), superoxide dismutase (SOD) activity, reduced glutathione (GSH) content, and total antioxidant capacity (TAC) in experimental groups.

Article Snippet: The activity of superoxide dismutase (SOD) was measured using the SOD Kit (CAT. NO. SD 25 21) from Bio-Diagnostics Co., Egypt, as described by the manufacturer.

Article Title: Effects of l -ascorbic acid on growth, non-specific immunity, antioxidant capacity, and intestinal and hepatopancreatic histology of red swamp crayfish, Procambarus clarkii

doi: 10.1038/s41598-023-48609-0

Figure Lengend Snippet: The oxidative stress biomarkers, including CAT ( A ), SOD ( B ), GPx ( C ), reduced GSH content ( D ), and MDA concentration ( E ) in the hepatopancreatic tissues of red swamp crayfish fed diets supplemented with various levels of l -ascorbic acid (LA) for 56 days (n = 3). Data were expressed as means ± SE. Bars labeled with different letters are statistically significantly different at P < 0.05.

Article Snippet: The diagnostic kits used for the evaluation of CAT and SOD enzyme activities were commercially purchased from MyBioSource Inc. (San Diego, California, USA) as per the directions provided by the producer and following the methods labeled by Aebi and McCord and Fridovich .

Techniques: Concentration Assay, Labeling
