Biochar‐Induced Shifts in Fungal Community Structure and Their Association With Soil Physical Properties in Degraded Soil From the Brazilian Semiarid

Land Degradation &Development, EarlyView.
ABSTRACT Soil degradation compromises ecosystem functioning. Biochar, a carbon‐rich amendment, has gained attention as a promising strategy to enhance soil structure and restore microbial balance. This study investigated the effects of two biochars, cashew bagasse biochar (CBB) and a co‐pyrolyzed biochar produced from sewage sludge and cashew pruning ...

Response of soil fungi and biological processes to crop residues in no-tillage system

Pesquisa Agropecuária Tropical, 2016
Soil management and crop rotation can directly affect the soil microbial community. This study aimed at determining soil quality indicators and soilborne fungi in a no-tillage system. A randomized blocks design, in a 3 × 2 factorial arrangement, was used.

Diflubenzuron Caused Mitochondrial Dysfunction, Ca2+ Homeostasis Disruption, and Intrinsic Apoptosis in Trophoblastic Cells

Environmental Toxicology, EarlyView.
ABSTRACT Diflubenzuron is used as an insect growth inhibitor, and its potential risk to human health was raised owing to the possibility of environmental residues and human exposure. This study aimed to investigate the toxic mechanism of diflubenzuron on trophoblastic cells such as HTR8/SVneo and JEG‐3 cells. We investigated mitochondrial function, Ca2+

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...
