Provedor de dados: 65
Autores: Ortolani,Enrico Lippi.
Fifteen lambs were fed diet with normal (0.11%) or deficient levels of sodium ( 0.035%), respectively, for five weeks on each diet. At the end of each period saliva was collected by three different methods: swabbing with a 5 x 5 x 1.25cm synthetic sponge, aspiration with a 15cm long plastic tube connected to a 20ml syringe and sucking with a 4mm x 45cm long plastic tube through a water-jet aspirator pump or an eletric motor pump. The volume of saliva collected/min and the salivary sodium: potassium ratio were analysed. Larger volume of saliva was obtained with the developed sucking apparatus than with the sponge or the syringe. There was no influence of the method of saliva collection on the values of salivary Na:K ratio in both periods. Nevertheless, the...

Provedor de dados: 58
Autores: Rosalem Junior,Wilson; Souza,Rodrigo Carvalho de; Andrade,Arnaldo Feitosa Braga de; Colombo,Ana Paula Vieira.
Actinobacillus actinomycetemcomitans (Aa) is considered a major etiologic agent of aggressive periodontitis but this species has also been associated with other forms of periodontal disease. Further, highly leukotoxic strains are related to severity of disease. The purpose of this study was to determine the prevalence of Aa and the occurrence of the leukotoxin gene 530-bp deletion in patients with generalized aggressive periodontitis (GAP) from a Brazilian population. Thirty periodontally healthy and 29 GAP subjects participated in the study. Full-mouth periodontal examination including probing pocket depth (PPD), clinical attachment level (CAL), supragingival biofilm (SB) and bleeding on probing (BOP) was carried out at 6 sites/tooth for all subjects....

Characterization of mouse salivary polypeptide secretion after oral administration of pilocarpine
Provedor de dados: 97
Autores: LÓPEZ-SOLÍS,REMIGIO; PUENTE,MARGARITA; DURÁN,VIVIANA; MORALES-BOZO,IRENE; KEMMERLING,ULRIKE; PARDO,RODRIGO; WENK,CAROLINA.
Mouse salivary secretion provoked by single or multiple oral administrations of the cholinergic agent pilocarpine was characterized. An accessory ad hoc device, manipulated by a single operator, was used to collect saliva from various mice simultaneously. A single challenge by pilocarpine in the range 40-400 µg provoked a dose-dependent secretory response. The secretory response lasted for about 40 minutes and was constituted by four clearly defined stages, namely: lag (5-10 min), maximal flow (10 min), slowering (15-20 min) and postsecretory rest. In this response, usual parameters were: maximal flow rate, 30-40 µl/min; total volume of saliva, 250-350 µl/mouse and total salivary protein, about 700 µg/mouse. Temporal desensitization of the secretory...

Detection of Helicobacter pylori in gastric biopsies, saliva and dental plaques of dyspeptic patients from Marília, São Paulo, Brazil: presence of vacA and cagA genes
Provedor de dados: 80
Autores: Rasmussen,LT; Labio,RW de; C Neto,A; Silva,LC; Queiroz,VF; Smith,MAC; Payão,SLM.
Helicobacter pylori, a gram-negative bacterium, possesses two important virulence factors: the vacuolating toxin (vacA), and the cytotoxin-associated gene product (cagA). The aim of the present study was to evaluate the presence of H. pylori in the stomach and oral cavity of humans and compare the cagA and vacA genotypes of H. pylori found in different samples (stomach, saliva and dental plaque) from the same patient. Gastric biopsies, saliva and dental plaques were obtained from 62 dyspeptic adults. DNA was extracted and evaluated for the presence of H. pylori and the alleles cagA and vacA. Persons with gastritis had a higher frequency of H. pylori -positive samples in the stomach while positive samples from gastric biopsies were significantly correlated...

Provedor de dados: 55
Autores: Gonçalves,Patrícia L.; Cunha,Carla B.; Busek,Solange C. U.; Oliveira,Guilherme C.; Ribeiro-Rodrigues,Rodrigo; Pereira,Fausto EL.
We examined the frequency of HCV-RNA in saliva samples from anti-HCV positive patients. Both plasma and saliva samples from 39 HCV patients (13 with normal liver enzymes, 19 with abnormal liver enzymes and 13 with cirrhosis) were investigated. Stimulated saliva and fresh plasma were centrifuged (900 x g,10 min) and stored at -70ºC, after the addition of guanidine isothiocyanate RNA extraction buffer. HCV-RNA was detected by RT- nested-PCR (amplification of HCV-cDNA for two rounds, using HCV primers 939/209 and 940/211). HCV genotyping was carried out by RFLP (using Mva I and Hinf 1 or Hae III and Rsa I restriction enzymes). Thirty-two out of 39 (82%; 95% CI=70-94%) anti-HCV-positive patients had HCV-RNA in plasma samples. Eight out of 39 (20.5%; 95%...

Haematophagous arthropod saliva and host defense system: a tale of tear and blood
Provedor de dados: 42
Autores: Andrade,Bruno B.; Teixeira,Clarissa R.; Barral,Aldina; Barral-Netto,Manoel.
The saliva from blood-feeding arthropod vectors is enriched with molecules that display diverse functions that mediate a successful blood meal. They function not only as weapons against host's haemostatic, inflammatory and immune responses but also as important tools to pathogen establishment. Parasites, virus and bacteria taking advantage of vectors' armament have adapted to facilitate their entry in the host. Today, many salivary molecules have been identified and characterized as new targets to the development of future vaccines. Here we focus on current information on vector's saliva and the molecules responsible to modify host's hemostasis and immune response, also regarding their role in disease transmission.

Provedor de dados: 55
Autores: Sampaio,Barbara Carvalho Fialho; Rodrigues,Jaqueline Polizeli; Meireles,Luciana Regina; Andrade Junior,Heitor Franco de.
ABSTRACT  Introduction: Vaccines are well-established public health interventions with major impacton the prevalence of infectious diseases, but outbreaks are occurring frequently due to pri-mary and secondary failures, despite high coverage. Surveillance of efficacy and duration ofinduced immunity is a difficult task as it requires invasive blood sampling in children andteenagers. Saliva can be an acceptable alternative source of IgG to assess vaccine efficacyand toxoplasmosis incidence. We investigated IgG response for measles, mumps, rubella,and T. gondii in saliva samples of vaccinated young people.  Methods: Saliva was collected from 249 public schools students from São Paulo, Brazil, aged7 to 13 years old, during an interactive exhibition on hygiene....

Minor Salivary Glands Morphology in Xerostomia Patients
Provedor de dados: 77
Autores: Liquidato,Bianca Maria; Barros,Mirna Duarte; Filho,Ivo Bussoloti; Pereira,Celina Siqueira Barbosa; Macéa,Maria Inêz Marcondes.
The minor salivary glands are found scattered throughout the oral mucosa, especially in the lips and soft palate mucosa. Several factors can cause xerostomia, whereas the salivary glands histological characteristics are also considered as factors for defining the etiology. Thus, the minor salivary glands biopsy represents an essential tool for attending the required diagnosis criterion in the classification of Sjögren's Syndrome patients, since it does not present risk for the patient. The objective of this study is to determine the histological description of the minor salivary glands obtained from the biopsies of xerostomia patients and to classify the minor salivary gland histological aspect as the Sjögren's Syndrome. Forty laminas of xerostomia...

Níveis de fósforo para caprinos: perda endógena fecal e exigência líquida para mantença
Provedor de dados: 86
Autores: Bueno,Mauro Sartori; Vitti,Dorinha Miriam Silber Schmidt.
Foram utilizados, no experimento, nove caprinos machos castrados, da raça Alpina, em dois períodos. Os animais permaneceram 28 dias em dieta experimental composta de feno e concentrado, sem suplementação de P, ou com 1g ou 2 g de P, na forma de fosfato bicálcico. No 21º dia os animais receberam injeção de 7,4 MBq de 32P na jugular, e coletaram-se amostras de sangue, fezes e urina, por sete dias, com o objetivo de avaliar o metabolismo do P. O aumento do consumo de P levou a aumento linear significativo do P excretado nas fezes, do P absorvido, do P endógeno fecal, da eficiência de absorção, e dos teores de P nas fezes e no plasma. O aumento do P endógeno fecal (Y) em função do consumo de P (X) pode ser descrito pela equação Y= 10,36 + 0,58X (r=0,94); a...

Prevalence of Pseudomonas aeruginosa and Acinetobacter spp. in subgingival biofilm and saliva of subjects with chronic periodontal infection
Provedor de dados: 58
Autores: Souto,Renata; Silva-Boghossian,Carina M.; Colombo,Ana Paula Vieira.
P. aeruginosa and Acinetobacter spp. are important pathogens associated with late nosocomial pneumonia in hospitalized and institutionalized individuals. The oral cavity may be a major source of these respiratory pathogens, particularly in the presence of poor oral hygiene and periodontal infection. This study investigated the prevalence of P. aeruginosa and Acinetobacter spp. in subgingival biofilm and saliva of subjects with periodontal disease or health. Samples were obtained from 55 periodontally healthy (PH) and 169 chronic periodontitis (CP) patients. DNA was obtained from the samples and detection of P. aeruginosa and Acinetobacter spp. was carried out by multiplex and nested PCR. P. aeruginosa and Acinetobacter spp. were detected in 40% and 45% of...
