Permeation studies of chlorpyrifos through skin and synthetic membranes to impr...

The in vitro percutaneous absorption assay is standardized, but the common use of 50 % ethanol in the receptor compartment for lipophilic compounds is questioned. In parallel, the demand for animal-free methodologies is driving the application of synthetic membranes without standardization guidelines. To address these issues, this study investigated the permeation of the lipophilic compound chlorpyrifos using d...

Application of curcuminoids in inflammatory, neurodegenerative and aging condit...

Curcumin, a natural compound found in turmeric, has shown promise in treating brain-related diseases and conditions associated with aging. Curcumin has shown multiple anti-inflammatory and brain-protective effects, but its clinical use is limited by challenges like poor absorption, specificity and delivery to the right tissues. A range of contemporary approaches at the intersection with bioengineering and syste...

Registered human trials addressing environmental and occupational toxicant expo...

Exposure to pollution is a worldwide societal challenge participating in the etiology and progression of different diseases. However, the scarce information hinders our understanding of the actual level of human exposure and its specific effects. Inadequate and excessive immune responses underlie diverse chronic diseases. Yet, it is unclear which and how toxicant exposures affect the immune system functions. Th...

Reassessment of the experimental skin permeability coefficients of polycyclic a...

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 ...

Metal alginates for polyphenol delivery systems: Studies on crosslinking ions a...

Incorporation of bioactive natural compounds like polyphenols is an attractive approach for enhanced functionalities of biomaterials. In particular flavonoids have important pharmacological activities, and controlled release systems may be instrumental to realize the full potential of these phytochemicals. Alginate presents interesting attributes for dermal and other biomaterial applications, and studies were c...

New Insights into Immunological Involvement in Congenital Disorders of Glycosyl...

Congenital disorders of glycosylation (CDG) are rare diseases with variable phenotypes and severity. Immunological involvement remains a largely uncharted topic in CDG, mainly due to lack of robust data. To better characterize immune-related manifestations’ prevalence, relevance, and quality-of-life (QoL) impact, we developed electronic questionnaires targeting (1) CDG patients and (2) the general “healthy” pop...
