In patients with parodontosis the distinct increase in salivary kallikrein secretion was found. In Wistar rats the intensity of age atrophy of alveoli dentalis correlated with BAEE-esterase activity of mixed saliva. Desalivation considerably decreased the rate of age atrophy of parodontosis in rats. Salivary kallikrein, penetrating in active form into parodontal tissues, caused the pronounced vasodilation in dogs and golden hamsters. By means of kallikrein preparations an intensive inflammatory-dystrophical process was reproduced in parodontal tissues of Wistar rats. The local treatment of patients with parodontosis by kallikrein inhibitors was found to be especially effective.

Salivary proteins of ticks can inhibit host hemostatic and inflammatory responses during the blood-sucking process of the parasites. A cDNA sequence, Hq021, was identified from a cDNA library of Haemaphysalis qinghaiensis. Hq021 encodes a mature protein containing 182 amino acids with a molecular mass of 20.

Treatment options for patients with metastatic castration-resistant prostate cancer include the use of radioligand therapy with Lu-PSMA-617. Although Lu-PSMA-617 can selectively target prostate cancer cells, salivary glands express PSMA on the apical lumen of the acinar epithelium. Xerostomia resulting from the use of radioligand therapy is common.

Background: Kallikrein-related peptidase 7 (KLK7) is a chymotrypsin-like serine protease which is essential for the desquamation of corneocytes and thus plays a pivotal role in maintaining skin homeostasis. In cancer, KLK7 overexpression was suggested to represent a route for metastasis through cleavage of cell junction and extracellular matrix proteins of cancer cells.
Methods: To comprehensively determine KLK7 protein expression in normal and neoplastic tissues, a tissue microarray containing 13,447 samples from 147 different tumor types and subtypes as well as 608 samples of 76 different normal tissue types was analyzed by immunohistochemistry.

Internal dosimetry supports safe and effective patient management during radionuclide therapy. Yet, it is associated with high clinical workload, costs, and patient burden, as patient scans at multiple time points (MTPs) must be acquired. Dosimetry based on imaging at a single time point (STP) has continuously gained popularity.

(1) Background: This cross-sectional investigation appreciated the role of serum C-reactive protein (CRP), several hematologic-cell markers, and salivary inflammation-related molecules [calprotectin (S100A8/A9), interleukin-1β (IL-1β), kallikrein] to predict periodontitis in patients with atherosclerotic cardiovascular disease (ACVD), arrhythmia, or both. Also, we appreciated the relationship between the inflammatory burden and periodontal destruction with the type of cardiac pathology. (2) Methods: Demographic, behavioral characteristics, periodontal indicators, blood parameters, and saliva samples were collected.
