Laser photolysis study of 1-aryl-3-methyl-5-(benzothiazole-2-yl) formazan phototransformation [PDF]

open access: yes, 2011
Photochromism of 1-aryl-3-methyl-5-(benzothiazole-2-yl)formazans in toluene has been investigated by the laser flash photolysis method. It was established that the photochromic transformations involve the triplet state of the initial chelate form of ...

Independent leaf and root responses to autumn freezing in perennial herbs: Insights from cutting and transplant manipulations

open access: yesGrassland Research, EarlyView.
In this study, we compared two sampling approaches to assess autumn freezing resistance. Our goal was to determine whether the commonly employed cutting method, which disrupts root‐tissue connectivity, provides a valid measure of true freezing resistance.

Cordycepin mediates neuroprotection against apoptosis via ERK/CREB signaling activation in Aβ1–42‐induced neuronal cell models

open access: yesIbrain, Volume 11, Issue 1, Page 84-97, Spring 2025.
This study demonstrates cordycepin's neuroprotective effects against Aβ1–42‐induced apoptosis in neuronal cells, mediated through the activation of the extracellular signal‐regulated kinase/cyclic AMP‐responsive element‐binding protein (ERK/CREB) signaling pathway.

A synthetic community promotes macadamia growth via root‐microbe interactions and systemic plant responses

open access: yesiMetaOmics, EarlyView.
We employed an 18‐month pot experiment and an integrated multi‐omics approach to elucidate the potential mechanisms underlying synthetic community (SynCom)‐mediated macadamia growth promotion. SynCom inoculation enhanced soil nitrogen cycling and potential nutrient (e.g., iron) acquisition.

Effect of Zinc Oxide Nanoparticles From Infant Formula Milk Powder on Colon Cells In Vitro

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Zinc is an essential trace element that participates in numerous metabolic processes; however, excessive exposure may interfere with the absorption of other metals, such as copper. In recent years, nanotechnology has experienced rapid growth, and zinc oxide nanoparticles (ZnO NPs) have garnered significant attention due to their versatile ...

Cellular Responses to Tartrazine and Sulfanilic Acid Exposure in BEAS‐2B Cells: Viability, Apoptosis, and DNA Damage

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Tartrazine is a synthetic azo dye widely used in food, pharmaceutical, and cosmetic products, resulting in extensive human exposure, while its toxicity and that of its primary metabolite, sulfanilic acid, remain controversial. Considering the reported association of tartrazine with hypersensitivity and allergic‐like reactions, human bronchial ...

Synthesis and Characterization of Juglone‐Derived cu (II), Mn (II) and Zn (II) Complexes and Investigation of Their Cytotoxic Activities Against Lung and Colon Cancer Cells in Vitro and in Silico

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Three new Zn (II), Cu (II) and Mn (II) complexes have been synthesized from 5‐hydroxy‐1,4‐naphthoquinone (HNQ). Elemental analysis, magnetic susceptibility, UV–Vis, IR and Mass spectrometry have all been used to explore the structural characterization of these compounds.

Melanoma Cells Exposed to Clomiphene Citrate Respond With Cell Cycle Arrest and Reduced Invasiveness

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Epidemiological studies have suggested that clomiphene citrate (CC) exposure may increase the risk of malignant melanoma, but mechanisms are unknown. We investigated the effects of CC on melanoma cell line A375. Cells were treated with CC at 2, 20, 200, and 2000 ng/mL, followed by assessment of cell viability and metabolism, cell cycle ...
