We have previously demonstrated that subgingival levels of nitrate-reducing bacteria, as well as the in vitro salivary nitrate reduction capacity (NRC), were diminished in periodontitis patients, increasing after periodontal treatment. However, it remains unclear if an impaired NRC in periodontitis can affect systemic health. To determine this, the effect of nitrate-rich beetroot juice (BRJ) on blood pressure was determined in 15 periodontitis patients before and 70 days after periodontal treatment (i.

The objective was to evaluate using unstimulated saliva in detecting and to compare the saliva and subgingival and mucosa membrane occurrence of this periodontal pathogen in patients diagnosed with advanced periodontitis. Patients with advanced forms of periodontitis ( = 220; mean age: 54.03 ± 03 years) at stage III/IV were sampled.

: Human β-defensin 2 (HBD2) is a protein that plays an important role in activating the immune system by modulating spinal pathways and the inflammatory response. According to previous research, HBD2 was proven to be important in chronic spontaneous urticaria (CSU) (their values were significantly elevated in CSU patients, with a significant correlation between HBD2 levels and the percentage of peripheral basophils, suggesting that elevated HBD2 levels may be a potential marker of basophil and mast cell activation), which led us to additional research on the HBD2 molecule in isolated chronic angioedema. The aim of this research is to examine HBD2 values in the saliva and serum of patients with isolated angioedema, as a potential biomarker of the disease.

Background: Over the past decade, saliva-based liquid biopsies have emerged as promising tools for the early diagnosis, prognosis, and monitoring of cancer, particularly in high-risk populations. However, challenges persist because of low concentrations and variable modifications of biomarkers linked to tumor development when compared to normal salivary components.
Methods: This study explores the application of differential scanning calorimetry (DSC)-based thermal liquid biopsy (TLB) for analyzing saliva and blood plasma samples from head and neck cancer (HNC) patients.

Article Synopsis
- The study aimed to explore mitochondrial transfer in dental mesenchymal stem cells (MSCs) and its impact on their ability to differentiate into odontogenic cells.
- Flow cytometry, immunostaining, and advanced imaging techniques were utilized to analyze the presence and significance of mitochondrial transfer in these cells, revealing its role in promoting odontogenic differentiation.
- The research found evidence of mitochondrial transfer through structures called tunneling nanotubes (TNTs) and showed that inhibiting this transfer affected key differentiation markers and gene expression related to odontogenesis.
