The distinct effect of titanium dioxide nanoparticles in primary and immortalized cell lines.

The titanium dioxide nanoparticles (NPs) have been applied to biomedical, pharmaceutical, and food additive fields. However, the effect on health and the environment are conflicting; thus, it has been reviewing several times. In this context, establishing standard robust protocols for detecting cytotoxicity and genotoxicity of nanomaterials became essential for nanotechnology development.

Preparation, Characterization and Biocompatibility Studies of Cotton Cellulose Nanofibers.

Cellulose nanofibers have mechanical properties that make them very attractive in a myriad of fields such as biomedicine, tissue engineering, biosensors, cosmetics and food packet products. To evaluate the potential health risks of airborne cellulose nanofibers, the cellulose nanofiber was prepared and characterized and then its pulmonary potential toxicity to a mouse model was studied. Cellulose nanofiber has been prepared by acid hydrolysis of cotton cellulose and characterized by transmission electron microscopy, zeta potential and X-ray diffraction analysis.

Isolated perfused udder model for transcriptome analysis in response to .

This study aimed to evaluate the transcriptional changes occurring in isolated perfused mammary alveolar tissue in response to inoculation with S. agalactiae and to identify the most affected biological functions and pathways after 3 h. Four udders taken at slaughter from cows with healthy mammary gland were perfused ex situ with warmed and gassed Tyrode's solution.

Cotton cellulose nanofiber/chitosan nanocomposite: characterization and evaluation of cytocompatibility.

Cellulose is a renewable polymer quite abundant on the Earth and very attractive for applications in the construction of eco-friendly biomedical products. The aim of this study was to investigate the chemical-physical characteristics of cotton cellulose nanofiber (CCN)/chitosan nanocomposite and its cytocompatibility with human embryonic kidney cells. First, the chemical composition, swelling ratio and surface topography of the nanocomposite were evaluated.

Direct and indirect toxic effects of cotton-derived cellulose nanofibres on filamentous green algae.

Recently, cellulose nanofibers (CNFs) have attracted considerable attention as natural, abundant polymers with excellent mechanical properties and biodegradability. CNFs provide a new materials platform for the sustainable production of high-performance nano-enable products for various applications. Given the increasing rates of CNF production, the potential for their release to the environment and the subsequent impact on ecosystem is becoming an increasing concern that needs to be addressed.
