Aflatoxins (AFs), notorious mycotoxins that pose significant risks to human and animal health, make biodegradation extremely crucial as they offer a promising approach to managing and reducing their harmful impacts. In this study, we identified a manganese peroxidase from (Mnp) through protein similarity analysis, which has the capability to degrade four AFs (AFB, AFB, AFG, and AFG) simultaneously. The gene encoding this enzyme was subject to codon optimization, followed by cold shock induction expression using the pColdII vector, leading to the soluble expression of manganese peroxidase (Mnp) in .

Background: Cerebrovascular accidents are known as a great cause of morbidity and mortality worldwide. Although there are known risk factors for ischemic stroke, the cases that cannot be justified with these risk factors are increasing. Toxic metals as a potential risk factor for other diseases in humans are assessed in this study in the CVA group and compared to controls.

Spin-polarized lasers have demonstrated many superiorities over conventional lasers in both performance and functionalities. Hybrid organic-inorganic perovskites are emerging spintronic materials with great potential for advancing spin-polarized laser technology. However, the rapid carrier spin relaxation process in hybrid perovskites presents a major bottleneck for spin-polarized lasing.
