Restoration of human tooth enamel

open access: yesBMEMat, EarlyView.
Human tooth enamel has remarkable properties but lacks self‐repair ability. Existing restorative materials cannot fully replicate enamel's microstructure and function, resulting in low restorative efficiency. This review summarizes the formation process and characteristics of enamel, and current restorative materials and future research directions are ...

The Landscape of Realized Homologous Recombination in Pathogenic Bacteria [PDF]

open access: yes, 2015
Recombination enhances the adaptive potential of organisms by allowing genetic variants to be tested on multiple genomic backgrounds. Its distribution in the genome can provide insight into the evolutionary forces that underlie traits, such as the ...

Functional CRISPR‐Cas9 knockout screening of the genetic determinants of human fibroblast migration propensity

open access: yesBiotechnology Progress, EarlyView.
Abstract Directional cell migration plays a central role in a wide range of physiological and pathological conditions, such as embryonic development or tumor metastasis. Steps involved in cell migration include cell polarization, formation of membrane protrusions at the cell front side and adhesion disassembly at the rear side, and a general ...

A Promising Antibacterial Inhibition of Propolis Extracts Against Carbapenem‐Resistant Bacteria Isolated From Clinical Samples

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The increasing inadequacy of antibiotics against multidrug‐resistant pathogens is a growing concern. In this study, the antibacterial activity of propolis extracts with different phenolic profiles against carbapenem‐resistant clinical isolates was investigated.

Streptococcus pyogenes-purpura fulminans as an invasive form of group A streptococcal infection

open access: yesAnnals of Clinical Microbiology and Antimicrobials, 2018
Background Streptococcus pyogenes is an uncommon pathogen of purpura fulminans, and the pathogenesis of S. pyogenes-purpura fulminans remains unclear because of paucity of cases. We reported a pediatric case of S.

Potent CRISPR-Cas9 inhibitors from Staphylococcus genomes. [PDF]

open access: yes, 2020
Anti-CRISPRs (Acrs) are small proteins that inhibit the RNA-guided DNA targeting activity of CRISPR-Cas enzymes. Encoded by bacteriophage and phage-derived bacterial genes, Acrs prevent CRISPR-mediated inhibition of phage infection and can also block ...

The Influence of Bacteriophage on Streptococcus pyogenes [PDF]

open access: yesJournal of General Microbiology, 1955
By the selective action of certain bacteriophages on cultures of susceptible streptococci it is possible to alter or enhance certain of their characteristics. The extractable M antigen may be greatly increased; non-mucoid strains may become completely mucoid with or without the increase in M antigen.

CRISPR Enabled Precision Oncology: From Gene Editing to Tumor Microenvironment Remodeling

open access: yesMed Research, EarlyView.
CRISPR technology has progressed from a prokaryotic immune system to a diverse suite of editing platforms, including Cas nucleases, base and prime editors, and RNA‐targeting enzymes. These advances enable precise genomic and epigenomic interventions, high‐throughput functional screening, and immune engineering.
