1. Chloride and sodium ion concentrations in saliva and sweat as a method to diagnose cystic fibrosis
Resumo Objetivo: O diagnóstico da fibrose cística depende do valor da concentração de íons de cloreto no teste do suor (≥ 60 mEq/mL - reconhecido como o indicador-padrão para o diagnóstico da doença). Além disso, as glândulas salivares expressam a proteína RTFC igualmente às glândulas sudoríparas. Nesse contexto, nosso objetivo foi verificar

2. Salivary protein polymorphisms and risk of dental caries: a systematic review
Abstract Dental caries is an oral pathology associated with both lifestyle and genetic factors. The caries process can be influenced by salivary composition, which includes ions and proteins. Studies have described associations between salivary protein polymorphisms and dental caries experience, while others have shown no association with salivary proteins g

3. Calcium, amylase, glucose, total protein concentrations, flow rate, pH and buffering capacity of saliva in patients undergoing orthodontic treatment with fixed appliances
OBJECTIVE: To evaluate qualitative and quantitative changes in the saliva of individuals undergoing orthodontic treatment with fixed appliances. METHODS: Salivary samples were collected from 50 individuals divided in two groups: Experimental Group - patients with fixed orthodontic appliances (n=25); and Control Group - subjects with no orthodontic appliances

4. Insights into preventive measures for dental erosion
Dental erosion is defined as the loss of tooth substance by acid exposure not involving bacteria. The etiology of erosion is related to different behavioral, biological and chemical factors. Based on an overview of the current literature, this paper presents a summary of the preventive strategies relevant for patients suffering from dental erosion. Behaviora

5. Análise da saliva de portadores de Fibrose Cística: composição inorgânica e abordagem proteômica
A Fibrose Cística (FC) é uma doença hereditária autossômica, recessiva e letal que apresenta certas dificuldades na realização do diagnóstico precoce e preciso. Devido ao comprometimento patológico essa doença assume grande importância e o diagnóstico precoce é decisivo para um melhor prognóstico. Este estudo teve por objetivo determinar a comp

6. Estrutura e ultra-estrutura das glândulas salivares de Cimex hemipterus (Fabricius, 1803) (Hemiptera: Cimicidae) / Structure and ultrastructure of the salivary glands of Cimex hemipterus (Fabricius, 1803) (Hemiptera: Cimicidae)
Cimex hemipterus is a hematophagous insect that can be an experimental host of the Trypanosoma cruzi and may play a role as vector of Chagas disease. This work analyzed the structure of the salivary glands of C. hemipterus. Adults were dissected and the salivary glands were analyzed in light microscopy and transmission electron microscopy. The secretory port

7. The role of sucrose in dental biofilm formation and in the protein composition of biofilm matrix formed in situ / Papel da sacarose na formação do biofilme dental e na composição de proteinas da matriz do biofilme formado in situ
Dental caries is a biofilm-dependent oral disease, and fermentable dietary carbohydrates are the key environmental factors involved with its initiation and development. Some hypotheses based on the structure, composition and ion kinetic aspects of biofilm have been suggested to explain the cariogenicity of biofilm formed in the presence of sucrose. Among the

8. Efeito de ions metalicos divalentes sobre a atividade de metaloproteases da matriz secretadas por celulas do tecido gengival
Matrix Metalloproteinases (MMPs) are a family of proteolytic enzymes that mediates the degradation of extracellular matrix. They are secreted as inactive proenzymes (zymogen), and they are thought to be activated in the tissue by cleavage of the propeptide. All members of this family have zinc and calcium binding to the active site. The MMPs take part in phy

9. Inhibition of dental plaque acid production by the salivary lactoperoxidase antimicrobial system.
Resting human whole saliva inhibited acid production by glucose-stimulated, homologous plaque. The degree of inhibition of plaque acid production correlated positively with the concentration of hypothiocyanite (OSCN-) ions in saliva. Supplementation of saliva with an appropriate combination of thiocyanate and hydrogen peroxide resulted in a significant incre

10. Antibacterial Activity of the Purified Peroxidase from Human Parotid Saliva
The peroxidase of human parotid saliva has been purified by concentration, gel filtration on Sephadex G-200, and ion exchange chromatography on Amberlite CG-50. The purified product was devoid of amylase activity, lysozyme activity, and immunoglobulin A (IgA). However, it had an inhibitory effect on the growth of Lactobacillus acidophilus in complete growth

Inhibitory effect of saliva on glutamic acid accumulation by Lactobacillus acidophilus and the role of the lactoperoxidase-thiocyanate system. J. Bacteriol. 91:1848–1853. 1966.—Saliva contains an antimicrobial system which inhibits the growth of Lactobacillus acidophilus, as well as a

12. Indirect evidence for the presence of non-specific anion channels in rabbit mandibular salivary gland acinar cells.
1. Intracellular pH (pHi) was measured using the fluorescent pH-sensitive dye 2',7'-bis(carboxyethyl)-5(6)-carboxyfluorescein in acini isolated from the rabbit mandibular salivary gland. 2. Stimulation of the acinar cells with acetylcholine (ACh) evoked an intracellular acidosis, the size of which was dependent on the HCO3-concentration in the bathing medium
