Periodontitis, one of the most prevalent dental diseases, causes the loss of bone and gum tissue that hold teeth in place. Several bacteria, commonly present in clinically healthy oral cavities, may induce and perpetuate periodontitis when their concentration rises in the gingival sulcus. Antibacterial effect against various Gram-negative and Gram-positive bacteria, including pathogenic and drug-resistant ones, has been shown for several distinct transient metal and metal oxide NPs.

Background: Society-wide initiatives to prevent human exposure to plastic residues include laws and policies. Such measures require citizens' support, which can be increased by honest advocacy and pedagogic projects. These efforts must have a scientific basis.

Calcium phosphates (CaPs) have been recently proposed as a bio- and eco-compatible alternative to UV filters in sunscreens, which are in the spotlight for being associated with health risks for both people and the environment. Here, natural CaPs extracted from fish bones have been tested as a booster of the sun protection factor (SPF), that is, as material working in synergy with UV filters to increase sunscreen UV-shielding efficiency, in combination with three of the most used UV filters, namely, octocrylene (OCR), octinoxate, and padimate-O, at different concentrations (10.0 and 20.

Producing monomeric phenols from lignin biopolymer depolymerization in a detachable and efficient manner comes under the spotlight on the fullest utilization of sustainable lignocellulosic biomass. Here, we report a low-loaded and highly dispersed Ru anchored on a chitosan-derived N-doped carbon catalyst (RuN/ZnO/C), which exhibits outstanding performance in the reductive catalytic fractionation of lignocellulose. Nearly theoretical maximum yields of phenolic monomers from lignin are achieved, corresponding to TON as 431 mol mol, 20 times higher than that from commercial Ru/C catalyst; high selectivity toward propyl end-chained guaiacol and syringol allow them to be readily purified.

Article Synopsis
- Circulating tumor cell (CTC) clusters may play a significant role in the spread of breast cancer, especially in advanced stages, but their presence in early stages is not well understood.* -
- This study utilized specialized titanium oxide-coated slides to identify clustered CTCs in patients with early breast cancer before they underwent surgery.* -
- The findings reveal that CTC clusters can be present in early stages of the disease, suggesting potential for early therapeutic interventions to target these clusters.*
