Zinc oxide nanoparticles (ZnO-NPs) are of interest in biomedical applications, environmental remediation, and agriculture. ZnO-NPs inhibit the growth of phytopathogenic fungi and bacteria. We have evaluated their effects on mitochondrial function and the induction of membrane damage, apoptosis, and DNA damage in human peripheral blood mononuclear cells (PBMC) in vitro.

In medical school and residency, learners are often not taught or given very brief information on conducting end-of-life planning conversations with patients.

A rare side effect of this medication is pneumonitis, which occurs in less than 1% of patients. We describe a case of an 83-year-old woman with a past medical history of microscopic polyangiitis, who presented with progressive dyspnea at rest, exacerbated on exertion, and associated with orthopnea that was attributed to CYC-induced pneumonitis.

Due to their promising characteristics for detecting toxic gases and volatile organic compounds (VOCs) compared with conventional techniques, these devices are expected to play a key role in home and public security, environmental monitoring, chemical quality control, and medicine in the near future. VOCs (e.

The performance and reliability of the sensitive materials in the presence of different volatile organic compounds (acetone, ethanol, and toluene), and other gases (CO, H and NO) were analysed. The ZnSnO, BaSnO, and CaSnO sensors showed sensitivities of 40, 16, and 8% ppm towards acetone, ethanol, and toluene vapours, respectively.
