In Vitro Assessment of Salivary Pellicle Disruption and Biofilm Removal on Titanium: Exploring the Role of Surface Hydrophobicity in Chemical Disinfection

Clinical and Experimental Dental Research, Volume 11, Issue 3, June 2025.
ABSTRACT Objectives Peri‐implantitis is mostly caused by a pathological biofilm that forms through complex processes, initiated by the formation of the salivary pellicle on implant surfaces. Understanding the nature of these pellicles and biofilm and how to remove them is important for preventing peri‐implant infections and improving the success of ...

Effect of nicotine on streptococcus mutans [PDF]

, 2014
Indiana University-Purdue University Indianapolis (IUPUI)Streptococcus mutans is a key contributor to dental caries. Smokers have increased caries, but the association between tobacco, nicotine, caries and S. mutans growth is little investigated.

Synthesis and Biological Activity of Ultrashort Antimicrobial Peptides Bearing a Non‐Coded Amino Acid

Journal of Peptide Science, Volume 31, Issue 5, May 2025.
Ultra‐short antimicrobial peptides containing acyl groups at the N‐terminus and the NCAA His* were prepared. The conformational analysis demonstrated that the peptides exhibiting the highest degree of structure were also those with the greatest antimicrobial activity. A promising candidate (P8) resistant to proteolysis with enhanced biological activity

Service evaluation to establish the sensitivity, specificity and additional value of broad-range 16S rDNA PCR for the diagnosis of infective endocarditis from resected endocardial material in patients from eight UK and Ireland hospitals [PDF]

, 2014
Infective endocarditis (IE) can be diagnosed in the clinical microbiology laboratory by culturing explanted heart valve material. We present a service evaluation that examines the sensitivity and specificity of a broad-range 16S rDNA polymerase chain ...

120 Years of “Lemurology”: A Qualitative Review of What We Have Learned

Biotropica, Volume 57, Issue 3, May 2025.
This review synthesizes about 120 years of scientific articles, starting in 1900, to summarize current advances in scientific studies about lemurs (Lemurology)”. It also addresses the conservation challenges these animals face, emphasizing the urgent need for effective protective measures.

Streptococcus oralis maintains homeostasis in oral biofilms by antagonizing the cariogenic pathogen Streptococcus mutans [PDF]

Molecular Oral Microbiology, 2018
SummaryBacteria residing in oral biofilms live in a state of dynamic equilibrium with one another. The intricate synergistic or antagonistic interactions between them are crucial for determining this balance. Using the six‐species Zürich “supragingival” biofilm model, this study aimed to investigate interactions regarding growth and localization of the

Antimicrobial Effect and Cytocompatibility After Using Different Decontamination Methods on Titanium Implant Surfaces: An In Vitro Study

Clinical Oral Implants Research, Volume 36, Issue 5, Page 626-639, May 2025.
ABSTRACT Aim To evaluate in vitro the antibacterial efficacy and cytocompatibility of different implant‐decontamination methods, using both 2D and 3D peri‐implant mucosa models. Methods Four decontamination methods [chlorhexidine (CHX), electrolytic treatment (GS), curcumin (CUR), xanthohumol (XN)] were compared in four independent experiments, three ...

Case of a Large Solitary Fibrous Tumour of the Pleura Complicated by Empyema

Respirology Case Reports, Volume 13, Issue 4, April 2025.
Solitary fibrous tumours of the pleura (SFTPs) are rare mesenchymal neoplasms, accounting for 4% of chest tumours, and they can rarely cause obstructive pneumonia attributable to airway obstruction. We report a rare case of SFTP complicated by empyema.
