Percutaneous absorption of two bisphenol a analogues, BPAF and TGSA: Novel In vitro data from human skin.

Bisphenol AF (BPAF) and TGSA are analogues of Bisphenol A (BPA). BPAF is used in polymer synthesis, while TGSA is applied in thermal papers. The EU classifies BPAF as toxic to reproduction and TGSA as a skin sensitizer.

Human in vitro percutaneous absorption of bisphenol S: Assessment of the skin reservoir and occlusion effects.

Bisphenol S (BPS) was introduced in many industrial and commercial applications as a presumed safer alternative to bisphenol A. However, concerns have been raised surrounding skin absorption and potential persistence of BPS and its related toxic effects in humans. A previous study revealed the likelihood of a reservoir building up in exposed skin.

Clickable polyethyleneimine incorporated into triblock copolymeric micelles as an efficient platform in the delivery of siRNA to NSCLC cells.

The efficacy of transfection vectors to cross the endosomal membrane into the cytosol is a central aspect in the development of nucleic acid-based therapeutics. The challenge remains the same: Delivery, Delivery, Delivery. Despite a rational and appropriate construct of triblock polymeric micelles, which could serve as an ideal platform for the co-delivery of siRNAs and hydrophobic anticancer drugs, we show here its inability to properly convey oligonucleotides to their final destination.

Comparison of different PCR amplification targets for molecular diagnosis of .

Molecular techniques are an alternative for the diagnosis of strongyloidiasis, produced by However, it is necessary to determine the best amplification target for the populations of this parasite present in a geographical area and standardize a polymerase chain reaction (PCR) protocol for its detection. The objectives of this work were the comparison of different PCR targets for molecular detection of and the standardization of a PCR protocol for the selected target with the best diagnostic results. DNA extraction was performed from parasite larvae by saline precipitation.

Obesity-induced hyperglycemia impairs oral tolerance induction and aggravates food allergy.

Obesity and type 2 diabetes (T2D) have been found to be associated with abnormalities in several organs, including the intestine. These conditions can lead to changes in gut homeostasis, compromising tolerance to luminal antigens and increasing susceptibility to food allergies. The underlying mechanisms for this phenomenon are not yet fully understood.
