Background: Formaldehyde is widely used in industry and in medicine as tissue fixative and disinfectant. It contains reactive molecules which have been known for its cytotoxic effects. In the present study, the probable protective properties of Rosa damacena aquatic extract, against the harmful effects of formaldehyde was evaluated by consideration of sperm count, motility, viability, morpholog...

We report the cases of three subjects who developed asthma after being exposed to formaldehyde dust or gas. For two subjects, specific bronchial provocation tests with formaldehyde gas did not cause significant bronchoconstriction, whereas exposure to formaldehyde resin dust did. One subject experienced asthmatic reaction after being exposed to formaldehyde resin dust and gas. These findings su...

Silver-Polyaniline (Ag-PANI) nanocomposites were prepared by in-situ oxidative polymerization of aniline monomer in sodium bis(2-ethylhexyl) sulfosuccinate (AOT) solution as an emulsifier. The synthesis of Silver-Polyaniline nanocomposites was investigated as a function of several parameters such as aniline concentration, concentration of emulsifier (AOT), concentration of oxidation agent and c...

Formaldehyde is an ubiquitous pollutant to which humans are exposed. Pathologists can experience high formaldehyde exposure levels. Formaldehyde-among other properties-induce oxidative stress and free radicals, which react with DNA and lipids, leading to oxidative damage and lipid peroxidation, respectively. We measured the levels of air-formaldehyde exposure in a group of Italian pathologists ...

Antimicrobial surfaces can be applied to break transmission pathways in hospitals. Polyaniline (PANI) and poly(3-aminobenzoic acid) (P3ABA) are novel antimicrobial agents with potential as non-leaching additives to provide contamination resistant surfaces. The activity of PANI and P3ABA were investigated in suspension and as part of absorbent and non-absorbent surfaces. The effect of inoculum s...

A highly sensitive, conductometric and label-free biosensor for the detection of immunoglobulin E (IgE) is developed based on the immobilzation of the IgE aptamer onto a single polyaniline nanowire electrochemically synthesized in a facile and controllable way.

Hierarchical nanocomposites of polyaniline (PANI) nanorods array on graphene oxide (GO) nanosheets are successfully obtained by dilute polymerization under -20 °C. They exhibit excellent water treatment performance with a superb removal capacity of 1149.4 mg g(-1) for Cr(VI).

A nanocomposite of colloidal graphene oxide (CGO) and polyaniline (PANI) was fabricated via in situ oxidation polymerization in the presence of CGO prepared via a modified Hummers method without a dopant, in which the graphene oxide was individually exfoliated. Its electrorheological properties and other physical characteristics were studied.

The DUF156 family of DNA-binding transcriptional regulators includes metal sensors that respond to cobalt and/or nickel (RcnR, InrS) or copper (CsoR) plus CstR, which responds to persulfide, and formaldehyde-responsive FrmR. Unexpectedly, the allosteric mechanism of FrmR from Salmonella enterica serovar Typhimurium is triggered by metals in vitro, and variant FrmR(E64H) gains responsiveness to ...
