Progress in research on osteoporosis secondary to SARS‐CoV‐2 infection

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This review explores the potential mechanisms, complications, risk factors, and future research directions related to osteoporosis secondary to SARS‐CoV‐2 infection. Key mechanisms include an imbalance between osteoclast and osteoblast activity driven by direct viral effects on bone, inflammation, hypoxia, dysregulation of noncoding RNAs, and metabolic

Does high sugar intake really alter the oral microbiota?: A systematic review

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1376-1390, December 2022., 2022
Abstract Objectives Diet is one of the main factors influencing the diversity and interactions of the oral microbiota. The purpose of this study is to determine the impact of sugar intake on the microbial diversity and bacteria that predominate under these conditions.

Antibacterial Siderophores of Pandoraea Pathogens and Their Impact on the Diseased Lung Microbiota

open access: yesAngewandte Chemie, EarlyView.
Genome mining of environmental and pathogenic Pandoraea species identified a conserved NRPS gene cluster and led to the discovery of novel siderophores, pandorabactins, which exert their antibacterial activity by depleting iron from competitors. Bioinformatic analysis of sputum from cystic fibrosis patients coupled with bioassays indicates that ...

A new CRISPR‐mediated Apc knockout allele leads to pyloric gland adenoma‐like gastric polyps in mice with C57BL/6;FVB/N mixed background

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The exon 16 of the mouse Apc gene was targeted with CRISPR/Cas9 system and a novel Apc knockout mouse model was generated by creating a frameshift mutation at codon 750 (ApcΔ750). The polyp number, polyp distribution and the overall survival of mice carrying the ApcΔ750 allele significantly differs between the F8‐FVB‐ApcΔ750 and F4‐B6;FVB‐ApcΔ750 mouse

Antibacterial effects of natural compounds on biofilm formation of Streptococcus mutans

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1426-1433, December 2022., 2022
Abstract Streptococcus mutans is the main cariogenic pathogen in the oral cavity, considered to contribute toward oral diseases. S. mutans is predominantly entrapped in plaque biofilms. Objectives In this study, we surveyed the antibacterial activity of natural compounds in terms of the biofilm production of S. mutans. Material and Methods We extracted
