Pure titanium or titanium alloys, and to a lesser extent, zirconium, are metals that are often
used in direct contact with host tissues. These metallic biomaterials are highly reactive, and on …

The titanium dioxide layer is composed mainly of anatase and rutile. This layer is prone to
break, releasing particles to the milieu. Therefore, corrosion may cause implant failure and …

Purpose.: To evaluate the effect of diesel exhaust particles (DEP) on the viability, proliferation,
apoptosis, secretion of cytokines (IL-6, IL-8, and TNF-α), and mucin gene transcription (…

Reactive O 2 species production triggered by particulate matter (PM) exposure is able to
initiate oxidative damage mechanisms, which are postulated as responsible for increased …

Metallic implants of titanium are used therapeutically in biomedicine because of its excellent
biocompatibility. However, no metal or alloy is completely inert. We have previously shown …

Despite the recent announcement of promising drug candidates to treat COVID-19, there is
currently no effective antiviral drug or vaccine. There is strong evidence that acute lung injury/…

Due to corrosion, a titanium implant surface can be a potential source for the release of micro
(MPs) and nano‐sized particles (NPs) into the biological environment. This work sought to …

Titanium and zirconium are biomaterials that present a layer of titanium dioxide (TiO 2 ) or
zirconium dioxide (ZrO 2 ). As a result of corrosion, microparticles can be released into the …

The layer of titanium dioxide (TiO 2 ) of the implant is chronically exposed to the internal
electrolyte milieu in the peri-implant biological compartment. Corrosion results from …

Air particulate matter (PM) can lead to extrapulmonary adverse reactions in organs such as
liver and heart either by particle translocation from the lung to the systemic circulation or by …
