The Trypanosoma and Toxoplasma spp, are etiological agents of diseases capable causing significant morbidity, mortality economic burden, predominantly in developing countries. Currently, there no effective vaccines for the caused by these parasites; therefore, therapy relies heavily on antiprotozoal drugs. However, treatment options parasitic limited, thus underscoring need new anti-protozoal agents. Here, we investigated anti-parasite action nanoparticles. We found that nanoparticles have...

Abstract Background Exercise-induced oxidative stress is a challenge in equine sports. This study aims at determining the effects of ergothioneine on heat shock protein-70 (HSP-70) following an endurance exercise 30 km by Arabian stallions. Molecular docking was also done to investigate interaction between ligand and using sulfogalactosylceramide sulfogalactoglycerolipid as standards. The involved total 18 clinically healthy stallions, with average age 6.7 ± 2.4 years weight 411.54 12.46 kg....
