Humic acid aggregates with laccase and decreases the performance of the enzyme ...

Laccases are among the best-rated enzymes for industrial and environmental applications, yet their use in bioremediation is limited by interference from environmental components like humic acid (HA). This study evaluated HA impact on the oxidation of 2,2 ′-azino-bis-(3-ethylbenzothiazoline-6-sulphonate (ABTS) and two model pollutants — anthracene and methyl orange — by laccase( mediator) systems. HA consistentl...

Unveiling the potential of olive oil production residues as adsorbent materials...

Olive oil is a nutritionally and economically valuable product whose global production has steadily increased, alongside the generation of large volumes of solid and liquid waste. Olive oil mill wastewater and solid residues such as olive pomace and olive stones have become major environmental concerns due to their high pollutant load. At the same time, these byproducts offer an opportunity: their valorization ...

Molecular mechanisms linking environmental toxicants to cancer development: Sig...

Human exposure to environmental toxicants with diverse mechanisms of action is a growing concern. In addition to well-recognized carcinogens, various chemicals in environmental and occupational settings have been sug-gested to impact health, increasing susceptibility to cancer by inducing genetic and epigenetic changes. Accordingly, in this review, we have discussed recent insights into the pathological mechani...

Towards the Development of Delivery Systems of Bioactive Compounds With Eyes Se...

Delivery systems carrying natural bioactive compounds for enhanced targeting and controlled release are capturing increasing attention. High loadings and sustained release are common design goals. However, in the case of compounds naturally present in human nutrition and physiology, further efforts are justified to optimize their bioactivity and promote clinical success. In this work, it is proposed a specific ...

Anthocyanins, effects in mitochondria and metabolism

Alterations in mitochondrial function, cellular redox signaling, and metabolism participate in the etiology and progression of different pathological conditions, such as diabetes, cancer, cardiovascular, and neurodegenerative diseases. Epidemiological, preclinical, and clinical studies indicate that anthocyanins afford therapeutic benefits for these pathologies. It is thus important to revise the effects of ant...

Identification of new targets of S-nitrosylation in neural stem cells by thiol ...

Nitric oxide (NO) is well established as a regulator of neurogenesis. NO increases the proliferation of neural stem cells (NSC), and is essential for hippocampal injury-induced neurogenesis following an excitotoxic lesion. One of the mechanisms underlying non-classical NO cell signaling is protein S-nitrosylation. This post-translational modification consists in the formation of a nitrosothiol group (R-SNO) in ...

Polyoxovanadate inhibition of Escherichia coli growth shows a reverse correlati...

Recently, a global analysis of the structure-activity-relationship of a series of polyoxometalates (POMs) revealed that the most active POMs were ascribed to be polyoxovanadates (POVs), especially decavanadate (V-10), which was very active against certain bacteria (Bijelic et al., Chem. Commun., 2018). The present study explores this observation and compares the effects of three POVs namely MnV11, MnV13 and V-1...
