The aggregation of mucoid and nonmucoid Pseudomonas aeruginosa by submandibular, parotid, and whole saliva from patients with cystic fibrosis (CF) and non-CF subjects was investigated. There were significant differences (P less than 0.01) in aggregation of mucoid and nonmucoid variants of P. aeruginosa by submandibular and whole saliva from CF patients and non-CF subjects. However, the differen...
BACKGROUND Recent evidence suggests that a lower extent of the retronasal aroma release correspond to a higher amount of ad libitum food intake. This has been regarded as one of the bases of behavioral choices towards food consumption in obese people. In this pilot study we investigated the hypothesis that saliva from obese individuals could be responsible for an alteration of the retro-nasal a...
OBJECTIVES To investigate the effect of saliva substitutes on enamel erosion in vitro. METHODS A total of 204 bovine enamel samples were embedded in acrylic resin and allocated to 17 groups (n=12). The specimens were eroded in an artificial mouth (3 days; 6×30 s/days, flow rate: 2 ml/min) using citric acid (pH: 2.5). Immediately after the erosive attacks, saliva substitutes (12 sprays, 3 gels...
adverse effects of dental materials, especially metals, have been an important issue in recent decades.the purpose of this study was to determine the amount of nickel released from stainless steel crowns in artificial saliva.in this in-vitro study, 270 stainless steel crowns were divided into five groups, each with nine subgroups. each group (i to v) was comprised of four, five, six, seven and ...
objectives: this study aimed to evaluate the effects of saliva contamination on the metallic bracket microleakage bonded with two moisture-tolerant bonding systems. materials and methods: ninety freshly extracted premolar teeth were randomly divided into six groups of 15 with the following treatments: g1 (control): after acid etching, assure primer and assure adhesive were applied to non-conta...
BACKGROUND Sand fly saliva has an array of pharmacological and immunomodulatory components, and immunity to saliva protects against Leishmania infection. In the present study, we have studied the immune response against Lutzomyia intermedia saliva, the main vector of Leishmania braziliensis in Brazil, and the effects of saliva pre-exposure on L. braziliensis infection employing an intradermal e...
INTRODUCTION We have previously shown that the concentrations of D-dimer are significantly elevated in saliva compared with plasma. Saliva offers several advantages compared with blood analysis. We hypothesised that human saliva contains plasminogen activator inhibitor-1 (PAI-1) and that the concentrations are not affected by the time of saliva collection. The aim was to adopt and validate an i...
BACKGROUND Although various acceptable and easy-to-use devices have been used for saliva collection, cotton swabs are among the most common ones. Previous studies reported that cotton swabs yield a lower level of melatonin detection. However, this statistical method is not adequate for detecting an agreement between cotton saliva collection and passive saliva collection, and a test for bias is ...
INTRODUCTION Congenital adrenal hyperplasia (CAH) or adrenogenital syndrome is the most common cause of female ambiguous genitalia. Management of such patients involves medical treatment using glucocorticoids such as hydrocortisone, prednisone or dexamethasone. Monitoring is done by measurement of 17-hydroxyprogesterone (17-OHP) or androstenedione in serum, plasma or saliva. The aim of this stu...
The aim of this study was to compare the pharmacokinetics of ethanol in saliva and blood according to gender and to evaluate the determination of ethanol in saliva for evidential sobriety testing. Twenty-four persons, 12 men and 12 women, took part in the experiments. The subjects received ethanol, as neat 40% v/v vodka, in the amount which should lead according to Widmark formula to the blood ...
