hazardous chemicals may enter the body by inhalation, ingestion, injection or dermal absorption. these exposure routes constitute the overall exposure burden on the body. most occupational exposure studies have focused on measurement of the concentration of air-borne contaminants and other possible routes of exposure are often overlooked. several studies have already highlighted the importance ...
Dermal fibroblasts are mesenchymal cells found between the skin epidermis and subcutaneous tissue. They are primarily responsible for synthesizing collagen and glycosaminoglycans; components of extracellular matrix supporting the structural integrity of the skin. Dermal fibroblasts play a pivotal role in cutaneous wound healing and skin repair. Preclinical studies suggest wider applications of ...
We investigated commercially available dermal sheep collagen either cross-linked with hexamethylenediisocyanate, or cross-linked with glutaraldehyde. In previous in vitro studies we could discriminate primary, i.e. extractable, and secondary cytotoxicity, due to cell-biomaterial interactions, i.e. enzymatic actions. To develop dermal sheep collagen for clinical applications, we focused in this ...
background pomegranate (punica granatum) is a significant source of bioactive compounds. however, its toxicity is not intensively studied. objectives the current study investigated the safety and tolerability of pomegranate peel extract (ppe) in balb/c mice. conclusions the current study showed that ppe had no toxicity and its use is suggested with potential applications against diseases. resul...
Currently, the major determinants of children's exposure to pesticides are not fully understood, and approaches for measuring and assessing dermal exposure in a residential setting have not been sufficiently evaluated. In one approach, dermal exposure is estimated using empirically derived transfer coefficients. To assess the feasibility of using this approach for assessing children's exposure ...
Objective(s): Silver nanoparticles have been widely used as new potent antimicrobial agents in cosmetic and hygienic products, as well as in new medical devices. Serious concerns have been expressed on the potential health risks of dermal applications of nanosilver containing consumer products (AgNPs), therefore regulatory health risk assessment has become necessary for the saf...
Introduction: Occupational Dermal exposure to Antineoplastic Drugs is the one of the most important routes in Healthcare staffs. Several antineoplastic drugs have been classified as carcinogens by the International Agency for Research on Cancer (IARC). Regards to this issue investigation on Dermal exposure to Antineplastic Drugs in healthcare staffs is nessessary. Method: In this Descriptive a...
Data on inhalational and potential dermal exposures during spray application of liquid biocidal products were generated. On the one hand, model experiments with different spraying devices using fluorescent tracers were carried out to investigate the influence of parameters relevant to the exposure (e.g. spraying equipment, nozzle size, direction of application). On the other hand, measurements ...
IMPORTANCE Acellular dermal matrices have many current and potential applications, but their long-term safety has not been extensively studied. In particular, limited information exists regarding such materials' resistance to infection. OBJECTIVE To assess the resistance to microbial penetration of common acellular dermal matrix materials used in reconstruction after skin cancer excision, tre...
objective: objective: dermal papilla and hair epithelial stem cells regulate hair formation and growth cycle. damage to or losing of these cells can cause hair loss. although several studies have claimed to reconstitute hairs using rodent cells in animal model, a stable human hair follicle reconstitution protocol needs more studies. here in this study we evaluated hair induction through injecti...
