1H Nuclear Magnetic Resonance-Linked Metabolomics Investigations of Broiler Poultry and Human Saliva
… in order to quantify ionic magnesium and calcium salivary concentrations via NMR characterisation of their chelation complexes with EDTA. At total of 82 samples were processed for 1H NMR analysis and metabolic compounds were identified. Concentrations of ionic levels were measured for each sample …

Variations in the amylolytic power and compostition of the saliva
… the variations in the character of the human saliva have had to do for the most part with those variations of the amylolytic power and composition which occur under normal conditions, and of the adaptation of the saliva to diets specific in character. In animals, however, the field of …

Sexual immune dimorphism in ecological context : the impact of estrogen on human immune function and development of bacteria killing assay.
… killing assay to assess innate immunity in human saliva. Females generally exhibit stronger immune responses than males, providing advantages in pathogen defense but increasing the risk of autoimmune diseases. Males, in contrast, have higher susceptibility to infections, influenced by the …

Three dimensional surface texture analysis for characterisation of enamel erosion
… have yet to be applied to dental erosion of human enamel. This project aimed to investigate the effect of acid-mediated erosive enamel wear on the micro-texture of polished (Group 1) and unpolished (Group 2) human enamel in vitro. 20 polished and 20 unpolished enamel samples were prepared and …

IMPROVEMENT OF METAGENOMIC TECHNIQUES TO BETTER UNDERSTAND THE ROLE OF CANDIDATE PHYLA RADIATION IN FOOD ALLERGIES
… Several researches indicate that, within the human microbiota, CPR bacteria play a role in immune modulation and consequently they might too in food allergy development. However, the detection of CPR is challenging due to their unique characteristics: small size, almost unculturable, unusual …

Aptamer-Based Detection of Salivary Melatonin for Circadian Rhythm Sleep Disorders Monitoring
… thereby leaving a lot to be desired. Salivary melatonin profiling can serve as a cost-effective and convenient method for diagnosing circadian rhythm sleep disorders, but there is still a challenge in measuring ultralow levels of hourly salivary melatonin secretion in real-time over 24 …

Measurement and validation of the nature of salivary adiponectin
… and atherogenesis. Levels of some hormones in saliva change in a fashion similar to that in plasma in response to a disease or physiological change. Since saliva is an easy to obtain biological fluid, measurements of salivary hormonal changes are preferred in diagnoses and treatments. …

Caratterizzazione proteomica di fluidi e tessuti in diverse condizioni fisio-patologiche
… focused on the proteomic characterization of human saliva from donors of different ages, starting from birth up to adult age, and pediatric brain tumor tissues. The first study has been performed in order to compare the acid-insoluble fraction of saliva from preterm with at-term newborns and …

Consumers and Their Drinking Water: Communicating Water Quality and Assessing the Reaction of Zerovalent Nanoiron (nZVI) with Saliva
Human senses for taste, odor, and visual assessment allow consumers to be selective when it comes to choosing their drinking water. In addition to wanting aesthetically pleasing water to drink, consumers want to know if their water is safe and may have misconceptions on what possible health risk …

Modeling contaminant transport in polyethylene and metal speciation in saliva
… measured at different pH in diluted artificial saliva using a cupric ion selective electrode. Three major proteins in human saliva: α-amylase, mucin and lactoferrin, were added in the artificial saliva and the impacts on the chemical speciation of copper were analyzed. Inorganic saliva …

The inhibition of HIV-1 activity by crude mucus and purified mucin (mucous glycoproteins) from saliva, breast milk and the cervical tract of normal subjects, HIV positive individuals and patients with HIV-AIDS
Human saliva, breast milk and cervical secretions contain several non-immunological components including mucins (mucous glycoproteins), which protect the gastrointesinal and female reproductive tracts and breast fed infants from bacterial, viral and fungal infections. In addition to their well …

Growth outcomes of Pseudomonas aeruginosa inhibitor of vertebrate lysozyme knockouts in conditions mimicking the cystic fibrosis lung environment
… the growth of PA<em> </em>in breast milk or human saliva, however, the role of Ivy knockouts should be explored in additional lysozyme-rich environments. The aim of this project is to identify the optimal conditions for an Artificial Sputum Medium (ASM) that can most closely resemble the …

Behavioral Response of Pacific Lamprey (Entosphenus tridentatus) to Predator Odors
… sturgeon (<em>Acipenser transmontanus</em>), human saliva, decayed lamprey, and river otter (<em>Lontra canadensis</em>). We conducted a 2 choice maze test and measured the number of entries (count) and duration of time spent in the test arm during a control trial and odorant trial. Results …

Interaction between tin/flouride-containing solutions and artificially created dental pellicles on erosion prevetion in vitro
… = 10). The specimens were incubated in clarified human saliva (CHS) for 24 h for pellicle formation and then they were subjected to a cycling procedure that included a 5-min erosive challenge (0.3-percent citric acid, pH 2.6); a 2-min treatment with the solution (between 1st, 3rd and 6th cycles); …

Enzyme microspheres for biosensing and cell signaling perturbation
Concentration of lactate in human blood or saliva is an important indicator for cardiac diseases. Conventional measurement of analytes in complex solution usually requires separation, which is time consuming. To bypass these problems, we developed enzyme based sensor arrays that rapidly and …

Studies of dietary nitrate induced nitrosative stress in the upper gastrointestinal tract
… mutagen responsible for this remains unknown. Human saliva contains substantial quantities of nitrite and is the main source of nitrite entering the stomach. It is derived from the enterosalivary recirculation of dietary nitrate and its reduction by buccal bacteria. Carcinogenic …
