Silica nanoparticles are less toxic to human lung cells when deposited at the air–liquid interface compared to conventional submerged exposure

Silica nanoparticles are less toxic to human lung cells when deposited at the air–liquid interface compared to conventional submerged exposure

BACKGROUND Investigations on adverse biological effects of nanoparticles (NPs) in the lung by in vitro studies are usually performed under submerged conditions where NPs are suspended in cell culture media. However, the behaviour of nanoparticles such as agglomeration and sedimentation in such complex suspensions is difficult to control and hence the deposited cellular dose often remains unknow...

Are Children Less Susceptible To COVID-19? A Case Series

Background The novel coronavirus (SARS-CoV-2 [2019-nCoV]) is the origin of several cases of pneumonia in Wuhan, Hubei province, China. According to the reported data, children are less common to be infected by COVID-19. Besides, their mortality rate is almost zero. Case Presentation In this article, we investigated six childr...

Fumonisin B-glucose reaction products are less toxic when fed to swine.

The effects of fumonisin B-glucose reaction products in swine diets was examined. Pigs were fed diets containing 528 micromol of total fumonisin B/kg (FB), 528 micromol of total FB-glucose adducts/kg (FB-G, 122 micromol of unreacted FB/kg), or 0 micromol of total FB/kg for 15 days to test the efficacy of the FB-G reaction products in detoxifying FB. Weight gain in FB pigs was lower than in FB-G...

kids and teenager are sleepy at school because the electronic media they have in their bedrooms leads them to have delayed sleep phase disorder (dspd)

bserved by many teachers that most of the time, mumbling and searching for their intended words, students complain why they have forgotten the words they have learned in the previous semesters. they ask for some new ways that may help them to recall and apply the learned words more efficiently, since as they declare one of the most important skills in foreign language learning is having a g...
