To elucidate the role of cardiolipin (CL) on redox behavior of cytochrome c (cyt c (III)), the photoreduction of cyt c using the photosensitization of zinc tetraphenylporphyrin in presence of triethanolamine (TEOA) as a sacrificial electron-donating reagent in various lipid media were studied. The initial rate of cyt c (III) photoreduction in various lipid, CL, l-alpha-phosphatidic acid (PA), dimethyldipalmitoylammonium bromide (DMPA) and Triton X-100 media were 1.0, 0.73, 0.80 and 0.67 micromol dm-3 min-1, respectively. The cyt c (III) photoreduction rate slightly increased by the addition of CL.

Picoxystrobin (PICO) poses a great threat to earthworms due to its widespread use in agriculture and its stability in soil. Mitochondria may be a sensitive target organ for the toxic effects of PICO on worms. Therefore, evaluating the effect of PICO on mitochondria can further understand the toxic mechanism of PICO to earthworms.

Mitochondrial holocytochrome c synthase (HCCS) is an essential protein in assembling cytochrome c (cyt c) of the electron transport system. HCCS binds heme and covalently attaches the two vinyls of heme to two cysteine thiols of the cyt c CXXCH motif. Human HCCS recognizes both cyt c and cytochrome c of complex III (cytochrome bc).

Article Synopsis
- Minor defects in the mitochondrial ATP-generating system can harm heart function in immature hearts, so this study explored various cardioplegic solutions.
- The experiment involved 41 male rats and compared the effects of three solutions (St. Thomas, Custodiol HTK, and Del Nido) during 1-hour and 3-hour ischemic periods.
- Results showed that the Del Nido solution offered the best mitochondrial respiration and ATP production compared to the other solutions, particularly after extended ischemia.

Article Synopsis
- Researchers developed a CuSe@LYC composite, using lycorine and CuSe nanoparticles, which can generate reactive oxygen species (ROS) when exposed to near-infrared-II (NIR-II) light.
- Treatment with the composite and NIR-II significantly reduced scar-related markers and induced cell death in hypertrophic scar fibroblasts, showing promise for safe clinical applications in managing scars.
