Abstract

Nanotoxicology is a major field of study that reveals hazard effects of nanomaterials on the living cells. In the present study, Copper/Copper oxide nanoparticles (Cu/CuO NPs) were prepared by the chemical reduction method and characterized by different techniques such as: X-Ray Diffraction, Transmission and Scanning Electron Microscopy. Evaluation of the toxicity of Cu/CuO NPs was performed on 2 types of cells: human lung normal cell lines (WI-38) and human lung carcinoma cell (A549). To assess the toxicity of the prepared Cu/CuOs NPs, the two cell types were exposed to Cu/CuO NPs for 72 h. The half-maximal inhibitory concentration IC50 of Cu/CuO NPs for both cell types was separately determined and used to examine the cell genotoxicity concurrently with the determination of some oxidative stress parameters: nitric oxide, glutathione reduced, hydrogen peroxide, malondialdehyde and superoxide dismutase. Cu/CuO NPs suppressed proliferation and viability of normal and carcinoma lung cells. Treatment of both cell types with their IC50's of Cu/CuO NPs resulted in DNA damage besides the generation of reactive oxygen species and consequently the generation of a state of oxidative stress. Overall, it can be concluded that the IC50's o...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
