Effects of Prenatal Arsenic Exposure Via Maternal Blood on Placental GLI3 Expression and Neonatal Outcomes

National Journal of Medical Research
Background: Prenatal arsenic exposure can harm both the mother and foetus by changing gene expression and impacting foetal growth. The study aimed to assess the impact of arsenic exposure on GLI3 expression in feto-placental tissue via maternal blood ...

Data Transparent and Polarization Insensitive All-Optical Switch based on Fibers with Enhanced Nonlinearity [PDF]

, 2014
We have developed a data transparent optical packet switch prototype employing wavelength conversion based on four-wave mixing. The switch is composed of an electro-optical control unit and an all-optical switching segment.

Assessment of Gold‐Mediated Male Reproductive Dysfunction in Male WISTAR Rats Through Sperm Analysis and Testosterone Measurement

Journal of Applied Toxicology, EarlyView.
ABSTRACT Gold has been used for centuries in both ornamental and medicinal contexts. More recently, gold compounds, containing ions or nanoparticles, have attracted attention for their anti‐inflammatory, anticancer, and diagnostic applications. Therefore, concerns about systemic toxicity and biodistribution have prompted investigations into the ...

Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

Journal of Applied Toxicology, EarlyView.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

Arsenic bioaccessibility in environmentally important arsenic minerals

Journal of Hazardous Materials
The potential risk to humans from incidental ingestion of As-contaminated soil and mine waste is influenced by the mineralogical composition of the As phases present. Using the Solubility Bioaccessibility Research Consortium in vitro assay, simulating gastric conditions, we determined the oral bioaccessibility of As in 16 environmentally important As ...

Exploring the Chemical Complexity and Toxicological Behaviour of Semi‐permanent Make‐Up Pigments: A Systematic Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Semi‐permanent make‐up (SPMU), or micropigmentation, involves implanting pigments into the dermal layer of the skin for cosmetic enhancement. Unlike topical cosmetics, which are rapidly cleared from the body, SPMU pigments persist in living tissues, raising unique toxicological considerations.

A new type of charged defect in amorphous chalcogenides

, 2004
We report on density-functional-based tight-binding (DFTB) simulations of a series of amorphous arsenic sulfide models. In addition to the charged coordination defects previously proposed to exist in chalcogenide glasses, a novel defect pair, [As4]--[S3]+

The Impact of Genetic Polymorphisms on Genotoxicity (DNA Damage) Among Children Exposed to Environmental Mutagens: A Systematic Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Children, as a particularly vulnerable group, are more susceptible to these mutagens due to their developing immune systems, higher physiological vulnerability, and increased exposure through behaviors like outdoor play and hand‐to‐mouth activities. This review aims to investigate the relationship between these environmental exposures, genetic

‘Felt sense of anomaly’‐type transdiagnostic dissociative experiences in adolescents: Endorsed phenomenology and plausible mechanisms

JCPP Advances, EarlyView.
Abstract Background Research indicates dissociative experiences (DE) are prevalent in adolescents. However, the exact phenomenology and underlying mechanisms of dissociation in adolescence have yet to be clarified. The current study explores the presentation of, and possible psychological factors maintaining, dissociation in this population.
