Purpose: To investigate the anti-caries effects of the school-based fluoride varnish (FV) application at 3-month intervals and ?weekly fluoride mouthrins?ing? (FMR) ?on primary teeth and to evaluate the anti-microbial effects of FV or FMR on cariogenic bacteria among Myanmar children.
Materials And Methods: A 6-month interventional study was conducted on 234 schoolchildren who were divided into three groups: group A received FV application at 3-month intervals, group B received weekly FMR,? and group C received no fluoride application. A clinical oral examination and caries risk tests were performed at baseline and the 6-month follow-up.
Results: Caries prevalence and ?the debris score did not change statistically significantly from baseline to the 6-month follow-up in all groups, whereas the dmfs score statistically significantly increased in group C (p = 0.001). The plaque and saliva scores of Dentocult SM statistically significantly decreased in group A (p = 0.049 and p = 0.006), but those scores statistically significantly increased in group C (p = 0.001 and p = 0.014) after six months. On the other hand, no statistically significant changes were observed in group B. Although the Cariostat scores decreased from baseline to the 6-month follow-up in group A and group B, but increased in group C, no statistically significant differences were observed in any of the groups.
Conclusion: Better anti-microbial effects were obtained for children who received FV application than for those who received FMR, but no statistically significant difference existed between the anti-caries effects of these two approaches.

The escalating prevalence of lifestyle and microbial diseases poses a significant threat to human well-being, necessitating the discovery and development of novel drugs with distinct modes of action. Addressing this challenge involves employing innovative strategies, and one current approach involves utilizing heterocyclic compounds to synthesize hybrid molecules. These hybrids have resulted from the fusion of two or more bioactive heterocyclic moieties into a single molecule.

In this work, laponite (LAP) was used to develop the silver (Ag) based nanocomposite for improved anti-bacterial action and wound healing properties. The amphiphilic co-polymers such as PLGA polymer was embedded with the surface of LAP molecules and polyethyleneimine (PEI) through the interaction of hydrophobic binding and it was formed as LAP/PLA-PEG/PEI formulation through the coupling chemistry. The Ag nanoparticles was loaded into formulation to develop LAP/PLA-PEG/PEI/Ag nanocomposite and characterized by different analytical techniques.

Background: Aerobic vaginitis (AV) is a state of abnormal vaginal microbiota, which is associated with increased numbers of aerobic, enteric bacteria and inflammation of the vaginal epithelium. Anti-microbial treatment combined with anti-inflammatory therapy could be useful in the treatment of this condition. It is known that calcitriol, the active form of vitamin D, plays an important role in modulating the immune response in several inflammatory diseases.

Microorganisms, crucial for environmental equilibrium, could be destructive, resulting in detrimental pathophysiology to the human host. Moreover, with the emergence of antibiotic resistance (ABR), the microbial communities pose the century's largest public health challenges in terms of effective treatment strategies. Furthermore, given the large diversity and number of known bacterial strains, describing treatment choices for infected patients using experimental methodologies is time-consuming.
