Recent research progress on the synthesis and biological effects of selenium nanoparticles

Frontiers in Nutrition, Journal Year: 2023, Volume and Issue: 10

Published: May 16, 2023

Selenium is an essential trace element for the human body, with chemical and physical characteristics of both metals nonmetals. has bioactivities related to immune system, antioxidation, anti-virus, anti-cancer. At same time, it also plays a role in reducing alleviating toxicity heavy metals. Compared inorganic selenium, organic selenium less toxic greater bioavailability. nanoparticles (SeNPs) have advantages high absorption rate, biological activity, low toxicity, can be directly absorbed by body converted selenium. gradually replaced traditional supplement broad prospects food medical industries. In this paper, chemical, physical, methods synthesis are reviewed, microbial nanoparticles, effects on crop growth, antibacterial, antioxidant, anticancer, anti-tumor systematically summarized. addition, we evaluate application nutrition enhancement, providing support animals, plants, humans.

Analysis of synonymous codon usage patterns in mitochondrial genomes of nine Amanita species

Frontiers in Microbiology, Journal Year: 2023, Volume and Issue: 14

Published: March 8, 2023

Codon basis is a common and complex natural phenomenon observed in many kinds of organisms.In the present study, we analyzed base bias 12 mitochondrial core protein-coding genes (PCGs) shared by nine Amanita species.The results showed that codons all species tended to end A/T, demonstrating preference for this codon. In addition, detected correlation between codon composition adaptation index (CAI), (CBI), frequency optimal (FOP) indices, indicating influence on bias. The average effective number (ENC) PCGs 30.81, which <35, strong Amanita. neutrality plot analysis PR2-Bias further demonstrated selection plays an important role obtained 5-10 (ΔRSCU > 0.08 RSCU 1) species, GCA AUU were most widely used codons. Based combined sequence value, deduced genetic relationship different found large variations them.This study promoted understanding synonymous usage characteristics evolution fungal group.

Microbial-assisted alleviation of chromium toxicity in plants: A critical review

Plant Stress, Journal Year: 2024, Volume and Issue: 11, P. 100394 - 100394

Published: Feb. 8, 2024

Soil contamination with chromium (Cr) is a serious and burgeoning environmental problem. The infiltration of excess Cr into the food chain causes number human health issues, including respiratory disorders, cardiovascular diseases, renal failure, several types cancer. pollution can be contained by different physical, chemical, biological remediation approaches. Physical chemical methods are costly hazardous to environment as they cause secondary pollution. Biological approaches such bioremediation that employ plants (phytoremediation) microbes eco-friendly, efficient, cost-effective. Nonetheless, conventional phytoremediation encounters limitations in large-scale use due restricted pool hyperaccumulator plant species, slow growth rate, limited biomass production, plant-contaminant specificity, contaminant-mediated oxidative stress plants. Interestingly, bacteria fungi have potential survive thrive under extreme conditions. Plant growth-promoting (PGPB) utilize siderophores, organic acids, biosurfactants, redox mechanisms, biomethylation convert metals soluble bioavailable forms. Further, these involved synthesizing phytohormones 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase, acquisition iron, nitrogen fixation, phosphorus solubilization, which improve biomass, thereby aiding phytoremediation. This literature review encompasses breadth research conducted over preceding decade, underscoring contemporary remedial primary focus on crucial role facilitating Cr. Moreover, this spotlights underlying mechanisms microbe-assisted betterment grown Cr-contaminated soils.
