Photocatalytic antimicrobial activity of thin surface films of TiO2, CuO and TiO2 /CuO dual layers on Escherichia coli and bacteriophage T4 [PDF]

open access: yes, 2008
TiO2 coated surfaces are increasingly studied for their ability to inactivate microorganisms. The activity of glass coated with thin films of TiO2, CuO and hybrid CuO/TiO2 prepared by atmospheric Chemical Vapour Deposition (Ap-CVD) and TiO2 prepared by a

X-Chromosome Inactivation [PDF]

open access: yesCurrent Biology, 1994
In female mammals, all X chromosomes except one are transcriptionally inactivated early in embryonic development. This is known as X-chromosome inactivation and is a form of dosage compensation, giving equal dosage of the products of X-linked genes in males and females. The mechanism is of considerable interest as an example of differential behavior of

Static Aerated Composting of African Swine Fever Virus-Infected Swine Carcasses with Rice Hulls and Sawdust

open access: yesPathogens, 2023
Identifying and ensuring the inactivation of the African Swine Fever virus in deadstock is a gap in the swine industry’s knowledge and response capabilities. The results of our study demonstrate that ASFv in deadstock was inactivated using static aerated

Tetracycline-Inactivating Enzymes [PDF]

open access: yesFrontiers in Microbiology, 2018
Tetracyclines have been foundational antibacterial agents for more than 70 years. Renewed interest in tetracycline antibiotics is being driven by advancements in tetracycline synthesis and strategic scaffold modifications designed to overcome established clinical resistance mechanisms including efflux and ribosome protection.
