Objectives: The neuroactive hormone oxytocin (OT) has significant influence on human behavior, and it has been measured peripherally in venous blood and in saliva in many behavioral neuroscience studies. Assessment of salivary hormone levels is popular due to non-invasiveness, but there is a controversy as to whether OT can be reliably measured in saliva and how possible time lags between plasma and salivary OT levels influence correlation.
Design And Methods: In order to shed light on the question whether salivary and plasma OT levels correlate, we designed an experiment where healthy young men had to look at a presentation of trustworthy faces on a computer screen (faces were taken from an established database in trust research). During three points in time, plasma and saliva samples were collected and analyzed using ELISA.
Results: Plasma and salivary OT levels did not correlate even when considering a time lag of 15 or 30 minutes.
Conclusions: Our results suggest that plasma and salivary OT levels do not correlate in healthy young men, and hence comparison of results across plasma and salivary studies is neither informative nor warranted. However, we recommend replicating this study based on mixed-gender samples.

Department of Orthodontics and Dentofacial Orthopedics, Chettinad Dental College & Research Institute, Chengalpet, Tamil Nadu, India.
Aim: This study intended to comprehend the effects of injectable platelet-rich fibrin (i-PRF) on anchor loss and space closure rates during the retraction phase of orthodontic treatment.
Materials And Methods: Twenty-four participants with malocclusion, necessitating extractions and space closure during orthodontic treatment, were enrolled and divided into two groups ( = 12 participants) group A: the experimental group was administered i-PRF on the maxilla/mandible, while group B: the control group did not. Measurements of the rate of space closure, anchor loss, and salivary enzyme activity were done before retraction (T0), after three weeks (T1), after six weeks (T2), and after nine weeks (T3).

Background: A novel anti-human epidermal growth factor receptor 2 (HER2) antibody-drug conjugate (ADC) GQ1001 was assessed in patients with previously treated HER2 positive advanced solid tumors in a global multi-center phase Ia dose escalation trial.
Methods: In this phase Ia trial, a modified 3 + 3 study design was adopted during dose escalation phase. Eligible patients were enrolled, and GQ1001 monotherapy was administered intravenously every 3 weeks.

This study explores the role of irisin and interleukins in parotid tumors by determining the tissue staining intensity of irisin, the salivary and plasma levels of irisin, and the plasma levels of IL-4, IL-6, IL-10 and TNF-alpha in individuals with parotid tumors. Forty-eight patients and forty healthy individuals were included to the study and allocated into four group. Benign Group I (pleomorphic adenoma), Group II (Warthin's tumor), Group III (mucoepidermoid carcinoma) and Group IV (benign parotid control group, healthy control group).

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.
