Tear Fluid SIgA, Noninvasive Biomarker of Mucosal Immunity?

Tear Fluid SIgA as a Noninvasive Biomarker of Mucosal Immunity and Common Cold Risk. Hanstock HG1, Walsh NP, Edwards JP, Fortes MB, Cosby SL, Nugent A, Curran T, Coyle PV, Ward MD, Yong XH. Author information ABSTRACT PURPOSE: Research has not convincingly demonstrated the utility of saliva secretory immunoglobulin-A (SIgA) as a biomarker of upper respiratory tract infection (URTI) risk, and disagreement exists about the influence of heavy exercise (“open-window theory”) and dehydration on saliva SIgA. Prompted by the search for viable alternatives, we compared the utility of tear and saliva SIgA to predict URTI prospectively (study 1) and assessed the influence of exercise (study 2) and dehydration (study 3) using a repeated-measures crossover design. METHODS: In study 1, 40 subjects were recruited during the…

Saliva/Hair Testing, Choosing your Laboratory Partner

COMPREHENSIVE SALIVA LABORATORY SERVICES Researchers seeking salivary lab support or contract research organizations (CRO) in search of a qualified saliva laboratory partner should utilize a lab that participates in a proficiency testing program; one that maintains industry leading, state-of-the-art saliva training on sample handling, storage protocols and assay techniques. If the guidance you seek needs to go beyond salivary handling, collection and testing—if your research demands the distinct advantage of a salivary bioscience pioneer as a partner—we’ve got you covered. WHAT SHOULD YOU EXPECT FROM A QUALIFIED SALIVA LAB? Are you getting the best results? Choosing the right lab is the most critical step towards accurate results. Utilize the lab comparison checklist to rank any lab against the Salimetrics SalivaLab or our CEO labs to…

Mindfulness Meditation best for beating Stress, UK research finds

Researchers at the University of Westminster conducted an 8 week trial measuring Salivary Cortisol, 68 People were recruited for the study which involved analysing levels of the stress hormone cortisol. A healthy stress response is to have a big burst in the morning called the cortisol awakening response(CAR), and lower levels throughout the day. The participants were examined after following such leisure pursuits as gardening, yoga and mindfulness meditation Whilst yoga saw only a slight improvement, gardeners CAR jumped by 20 per cent, while the mindfulness group saw their cortisol awakening response leap by 52 per cent. Those who enjoyed the meditation gained an even bigger boost, with CAR rising to 78 per cent. Previous studies have shown that mindfulness can decrease self-reported stress levels…

How to Achieve High-Quality Salivary Cortisol Data for Your Research

A recent study shows better assays and better labs are consistently producing better salivary bioscience study data. The research team analyzed salivary cortisol measurement error between established-qualified international academic-research laboratories using Salimetrics Assays. A new study published in BioMed Central Research Notes shows that using an established-qualified lab provides the best opportunity for consistent, reproducible data. Dr. Calvi and collaborators explored the possibility that inconsistent findings due to variations in assay performance from different laboratories may contribute to unsystematic error in salivary measurements, specifically for salivary cortisol. To test this, researchers sent aliquots of 100 saliva samples to 9 different academic labs that routinely measure salivary cortisol to determine the variability between labs and the reproducibility of salivary cortisol measurements. The results identified only 1.76%…

Measurement of Salivary Cortisol and Secretory Immunoglobulin A in Field Studies of Athletes

Here we highlight research from Australia regarding Factors Affecting Measurement of Salivary Cortisol and Secretory Immunoglobulin A in Field Studies of Athletes Pritchard BT1, Stanton W1, Lord R2, Petocz P3, Pepping GJ4. Author information 1. School of Physiotherapy, Australian Catholic University, Brisbane, QLD, Australia. 2.  School of Science, Australian Catholic University, Brisbane, QLD, Australia. 3. Department of Statistics, Macquarie University, Sydney, NSW, Australia. 4. School of Exercise Science, Australian Catholic University, Brisbane, QLD, Australia. Abstract AIMS:  Biological and lifestyle factors, such as daily rhythm, caffeine ingestion, recent infection, and antibiotic intake, have been shown to influence measurements of salivary cortisol (SC) and secretory immunoglobulin A (sIgA). Current methodology in unsynchronized, field-based biomarker studies does not take these effects into account. Moreover, very little is known about the combined effects of…

Where does Saliva come from?

Human Saliva is produced by pairs of glands located symmetrically on both sides of the head: the parotids, the submandibulars (also known as the submaxillarys), and the sublinguals. In addition to the primary glands, there are also hundreds of smaller glands located in the lips, cheeks, tongue, and palate. Although the parotid glands are the largest in size, they produce only about 20% of the total saliva in the unstimulated rest state, and the minor glands and the sublinguals together contribute only about an additional 15%. The submandibular glands are by far most active in the unstimulated state, and they are estimated to produce about 65% of the total rest volume.
