The earliest studies in the late 19th century on Streptococcus pneumoniae (S. pneumoniae) carriage used saliva as the primary specimen. However, interest in saliva declined after the sensitive mouse inoculation method was replaced by conventional culture, which made isolation of pneumococci from the highly polymicrobial oral cavity virtually impossible. Here, we tested the feasibility of using ...

OBJECTIVES The aim of this study was to compare stimulated whole saliva 17beta-estradiol of menopausal women with/without oral dryness (OD) feeling, and evaluate the relationship between saliva 17beta-estradiol and severity of OD feeling. METHODS A case-control study was carried out in 76 selected menopausal women aged 41-77 years with or without OD feeling (38 as case and 38 as control) cond...

Immunologic analysis, originally developed for urine, is also effective for saliva. Using fluorescence polarization immunoassay (FPIA), we analyzed saliva directly (without former extraction) for barbiturates, opiates, cannabinoides, amphetamines, and cocaine. By using calibration standards, cut-off limits were established. The presence of benzodiazipines was tested using radioimmunoassay. Subs...

introduction: to assess the salivary composition of proteins and minerals in smokers compared with non-smokers.   materials and methods: in this study we compared the total protein and ca, na, k, mg, pb of whole saliva in two groups of men (28 smokers and 31nonsmokers) aged between 29-41years.   results: fifty-nine participants were evaluated. the mean age was 33.14±5.32 years among smokers and...

INTRODUCTION A biomarker of the exposure to the tobacco smoke is cotinine - a nicotine metabolite with a half-life about 16 hours. Analysis of cotinine concentration in biological material allows objective assessment of the cigarette smoking status and environmental exposure to the tobacco smoke. AIM OF THE STUDY The aim of the study was evaluation of the influence of method of saliva collect...

Resin-based dental restorative materials contain allergenic methacrylate monomers, which may be released into saliva after restorative treatment. Monomers from resin-based composite materials have been demonstrated in saliva in vitro; however, studies analyzing saliva after restorative therapy are scarce. The aim of this study was to quantify methacrylate monomers in saliva after treatment with...

Saccharification of cellulose is a promising technique for producing alternative source of energy. However, the efficiency of conversion of cellulose into soluble sugar using any currently available methodology is too low for industrial application. Many additives, such as surfactants, have been shown to enhance the efficiency of cellulose-to-sugar conversion. In this study, we have examined fi...

DNA methylation has become increasingly recognized in the etiology of psychiatric disorders. Because brain tissue is not accessible in living humans, epigenetic studies are most often conducted in blood. Saliva is often collected for genotyping studies but is rarely used to examine DNA methylation because the proportion of epithelial cells and leukocytes varies extensively between individuals. ...

A quantitative, voxel-wise meta-analysis was performed to investigate the cortical control of water and saliva swallowing. Studies that were included in the meta-analysis (1) examined water swallowing, saliva swallowing, or both, and (2) reported brain activation as coordinates in standard space. Using these criteria, a systematic literature search identified seven studies that examined water s...

Hepatitis C virus can be detected in blood and other bodily fluids, such as saliva. The aim of this study was to detect and quantify the HCV-RNA in saliva and plasma from patients with chronic hepatitis C infections, as well as check the level of viral load in sex groups (age, ethnicity and virus subtypes). Whole saliva and blood from 70 patients with chronic hepatitis C infections attended at ...
