Background And Objectives: To investigate whether salivary contamination during various stages of the bonding procedures of Xeno III and Clearfil SE Bond influences shear bond strength.
Materials And Methods: THE OCCLUSAL SURFACES OF THIRTY SIX MAXILLARY PREMOLAR TEETH WERE GROUND AND DIVIDED INTO TWO GROUPS CONTAINING EIGHTEEN SPECIMENS EACH, WHICH WAS SUBDIVIDED INTO THREE SUB GROUPS: Group I - Xeno III, Group II - Clearfil SE Bond, Subgroup A - Uncontaminated (control), Subgroup B - Contaminated with saliva before application and light curing, Subgroup C - Contaminated with saliva after light curing. Composite resin Filtek Z350 was packed using Teflon mold cured and subjected to shear bond strength analysis using universal Instron machine.
Results: Statistical analysis was made using One-way ANOVA and Tukeys HSD test. Clearfil SE Bond showed very high statistically significant reduction in the bond strength, when salivary contamination took place after light curing; whereas, Xeno III showed very high statistically significant reduction when salivary contamination took place before application and light curing.
Conclusion: Clearfil SE Bond showed more tolerance to salivary contamination of dentin and higher shear bond strength value, when compared to Xeno III.

S100-positive stroma in salivary gland basal cell adenomas: a neoplastic component with CTNNB1 mutations.

Division of Translational Oncoimmunology, Aichi Cancer Center Research Institute, Nagoya, Japan.
Basal cell adenomas (BCAs) are benign epithelial tumors of the salivary gland, characterized by the proliferation of basaloid and luminal cells. In addition, a distinctive spindle cell stroma, that is immunohistochemically-positive for S100, is often observed in BCAs. Based on the ultrastructural findings, the S100-positive stroma was presumed to originate from neoplastic myoepithelial cells.

Aim: aliva extracellular vesicles (EVs) serve as a significant reservoir of biomarkers that may be of clinical use in disease diagnosis. Saliva, however, contains EVs of both host- and bacterial- origin. Identifying suitable EVs for disease diagnosis involves enriching host EVs and limiting non-host contamination with effective isolation methods.

In crime investigations, the unambiguous identification of biological traces can be decisive for framing the events. In this study, we applied proteomics to analyze scant amounts of biological residues in the context of an alleged rape case, focusing on the detection of traces of vomit. We used high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) and two distinct proteomic workflows to identify proteins and possible proteolytic peptides in biological residues from clothing, bedding, and car upholstery from the alleged crime scene.
View Article and Find Full Text PDFBackground: Ozonated water is expected to be an effective disinfectant for SARS-CoV-2 present on environmental fomites; however, ozone is consumed by organic substances, resulting in attenuation of its effect. SARS-CoV-2 present in saliva can contaminate environmental surfaces; therefore, it is essential to understand the effect of organic substances in saliva on the disinfectant properties of ozonated water.
Aim: To assess organic factors in saliva and the extent to which they diminish the effect of ozonated water on SARS-CoV-2.
Salivary Antibody Responses to Potentially Waterborne and Environmentally Transmitted Infections Among Two Tribal Nations in the Southwest United States.

Article Synopsis
- * A total of 531 saliva samples were analyzed from two Tribal Nation festivals and compared with 453 samples previously collected in the Midwest, employing logistic and linear regression models.
- * Results indicated varying seroprevalences of specific infections, with higher antibody responses to certain noroviruses and unique associations between lifestyle factors (like water consumption and animal contact) and infection rates in the Tribal populations.
