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.

Practical Aspects of Using Multifractal Formalism to Assess the Morphology of Biological Tissues.

Unlabelled: is to identify practical aspects of using multifractal formalism to assess the morphology of biological tissues.

Materials And Methods: The objects of the study were histological images of lung tissues of Wistar rats without pathology and with detected pathological changes, obtained at 50×, 100×, 200× magnifications. Image processing was carried out using the ImageJ/Fiji universal software.

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.

Study of Hematological Parameters and Morphometric Indices of Erythrocytes in Rats Exposed to Calcium Oxide Nanoparticles.

In female Wistar rats, we studied the effects of daily 20-day administration of intragastric suspension of nanosized calcium oxide on hematological indices (the counts of erythrocytes, leukocytes, platelets, hemoglobin, hematocrit, basophils, lymphocytes, monocytes, stab/segmented neutrophils, and the eosinophil-to-lymphocyte ratio) and morphometric parameters of erythrocytes (equivalent Feret's diameter, sphericity, aspect ratio, and convexity). The study revealed significantly (up to 3.1 times) decreased levels of hemoglobin, platelets, hematocrit, averaged content of hemoglobin in erythrocyte, and platelet volume relatively to the control values.
