Activatable smart contrast agents for photoacoustic imaging

Smart Molecules, EarlyView.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Untreated Hair Dye Effluents Enter the Environment: Are They a Threat to Human Health?

Environmental Toxicology, EarlyView.
ABSTRACT The effluents generated during the process of hair dyeing exhibit a complex composition, comprising chemical compounds with varying toxicity levels. While the adverse impact of hair dyes on human health is acknowledged, there is a notable absence of studies addressing the toxicity associated with effluents produced during these activities. The

Cyanogenic Compounds, Physicochemical Parameters and Metals in Water From Cassava Processing Areas: A Study in the Brazilian Amazon, Using Multivariate Analysis

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the water quality of artesian wells and effluents generated in cassava processing in a rural area of Bragança, Pará, with emphasis on physicochemical parameters, multielement composition, and cyanogenic compounds. The well water presented specific nonconformities, highlighting pH values below the recommended level and high

Study of factors controlling the photoprotection capacity of the thylakoid membrane

, 2010
PhDPlants require light for the process of photosynthesis, but excess of light absorption can cause photooxidative damage. To avoid this damage, plants have evolved a photoprotective mechanism to dissipate excess light energy as heat in a process ...

Beyond Removal Efficiency: Environmental Risk Assessment of Tartrazine Degradation via ZnO and TiO2 Nanoparticles in Mussels

Environmental Toxicology, EarlyView.
ABSTRACT Tartrazine (TZ) is a widely used synthetic azo dye with high aqueous stability, resulting in persistence in wastewater. Photoreactive nanomaterials, principally zinc oxide (ZnO) and titanium dioxide (TiO2) nanoparticles (NPs), are frequently employed for dye removal under light‐exposed conditions; nevertheless, their ecotoxicological ...

Non Photochemical Quenching mechanism in higher plants and in the unicellular alga Chlamydomonas reinhardtii

, 2010
Light is a necessary ecological factor for oxygenic photoautotrophic organisms. Plants and algae require light for life but it can sometimes become a limiting factor or even cause stress events.
