Sub-acute Inhalation Exposure to Aluminum Oxide Nanoparticles and its Effects on Wistar Rats as Opposed to the Micro-sized Chemical Analog.

Introduction: Aluminum oxide nanoparticles (AlO NPs) are widely used in various productions. Simultaneously, many research works report the toxic effects of this nanomaterial. Given that, there is a growing risk of negative effects produced by AlO NPs on public health.

Porous PZT Films: How Can We Tune Electrical Properties?

Porous ferroelectric lead zirconate titanate (PZT) films are a promising material for various electronic applications. This study focuses on understanding how the structure-directing agent, polyvinylpyrrolidone, can alter the structure and electrical properties of porous PZT films prepared through chemical solution deposition. Films with various porosities of up to ~40 vol.

Peculiarities of bioaccumulation and toxic effects produced by nanoparticles of molybdenum (VI) oxide under multiple oral exposure of rats: examination and comparative assessment.

Introduction: Molybdenum (VI) oxide nanoparticles (MoO3 NPs) are widely used in various economic activities. This creates elevated risks of exposure to this nanomaterial for workers and population in general and, consequently, there can be an increased number of developing pathological changes caused by exposure to MoO3 NPs.

Objective: To examine and comparatively assess peculiarities of bioaccumulation and toxic effects produced by MoO NPs under multiple oral introductions.

Features of Bioaccumulation and Toxic Effects of Copper (II) Oxide Nanoparticles Under Repeated Oral Exposure in Rats.

Background: Currently, the range of copper (II) oxide nanoparticles' (CuO NPs) applications is expanding and the global production of CuO NPs is increasing. In this regard, the risk of exposure of the population to this nanomaterial is increasing.

Objective: The aim of the study is to investigate the patterns of bioaccumulation and toxic effects of CuO NPs after multiple oral exposures.

Peptides With Triplet-Tryptophan-Pivot Promoted Pathogenic Bacteria Membrane Defects.

Development of probiotic-ineffective antimicrobial peptides (AMPs)-based coatings that can kill pathogenic bacteria at low concentrations but are essentially harmless (even high concentrations) to probiotic organisms is a relatively new trend for therapy against GI tract infections. In this study, a series of triplet-tryptophan-pivot peptides with various hydrophilic amino acids was constructed. One AMP in particular, S7, showed bactericidal activity against , , and antibiotic-resistant , yet was shown to be harmless to , a key GI tract commensal.
