Iron deficiency with or without anemia is considered the most widespread nutritional deficiency in the world. To diagnose iron deficiency anemia (hemoglobin and ferritin measurement), a venous blood sample is necessary. Whole saliva is a potentially attractive fluid for disease biomarker discovery and diagnostic efforts, because it is readily available from most individuals, can be easily collected and the collection procedure is non-invasive. The iron storage protein ferritin is too big, to be secreted into saliva. However, the main iron regulatory protein hepcidin is a very small protein and there is some evidence for hepcidin detection in saliva. The production of serum hepcidin positively correlates with serum ferritin, thereby reflecting patient's iron status. Whether hepcidin is detectable in saliva and whether saliva hepcidin correlates with serum hepcidin with current assays, needs to be tested.

The aim of the present study is to investigate epigenetics based modifications and biomarkers in the saliva and blood in diabetic patients.
There is an interest to assess nutritional status of vitamins in humans in a non-invasive way, i.e. by avoiding taking blood samples. Saliva could potentially be an alternative to blood fo...
Objective The aim of this study was to test a protocol for the extraction of high quality genomic DNA from saliva samples obtained with mouthwash and taken from patients with periodontal d...
This study proposes to demonstrate the feasibility of measuring 2H:1H and 18O:16O in saliva and breath by comparing the natural abundances of 2H:1H and 18O:16O in saliva and urine of un-do...
In tuberculosis patients, salivary concentrations will be compared to plasma/serum concentrations of several anti-tuberculosis drugs. If salivary concentrations correctly represent blood c...
Saliva based diagnostics is a rapidly evolving field due to the large diagnostic potential and simple sample collection. Currently only few individual molecules were investigated for their diagnostic ...
Saliva is a multifaceted bodily fluid that is often taken for granted but is indispensable for oral health and overall well-being in humans. Although mainly comprised of water (99.5%), proteins, ions ...
The aim was to measure and compare fluoride concentrations in oral mucosa and saliva following a single brushing with either 1,450 or 5,000 ppm fluoride toothpaste. Fourteen healthy participants provi...
Whole Exome Sequencing (WES) utilises overlapping fragments prone to sequencing artefacts. Saliva, a non-invasive source of DNA, has been successfully used in WES studies on various platforms. This st...
Forensic saliva identification represents an increasingly useful auxiliary means of crime investigations, particularly in sex crimes. Salivary bacteria detection techniques have been shown to be viabl...
A solution used for irrigating the mouth in xerostomia and as a substitute for saliva.
Sampling of blood levels of the adrenocorticotropic hormone (ACTH) by withdrawal of blood from the inferior petrosal sinus. The inferior petrosal sinus arises from the cavernous sinus and runs to the internal jugular vein. Sampling of blood at this level is a valuable tool in the differential diagnosis of Cushing disease, Cushing syndrome, and other adrenocortical diseases.
A blood group related both to the ABO and P systems that includes several different antigens found in most people on erythrocytes, in milk, and in saliva. The antibodies react only at low temperatures.
Forms of hepcidin, a cationic amphipathic peptide synthesized in the liver as a prepropeptide which is first processed into prohepcidin and then into the biologically active hepcidin forms, including in human the 20-, 22-, and 25-amino acid residue peptide forms. Hepcidin acts as a homeostatic regulators of iron metabolism and also possesses antimicrobial activity.
The discharge of substances from the blood supply via diffusion into the SALIVA from the ORAL MUCOSA or from the SALIVARY GLANDS.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
