Normalmente essa infecção é assintomática, porém, quando os sinais e sintomas estão presentes podem causar sangramento das mucosas, edema local, ardor ou outras sensações dolorosas. Os medicamentos tópicos, como a nistatina e o miconazol, têm sido utilizados, entretanto, o efeito diluente da saliva, movimentação da língua e da musculatura bucal reduzem a dose desses agentes a concentrações subterapêutica, além do alto índice de recorrência da infecção. Assim, é importante a procura por novos antifúngicos, que sejam eficientes e não tóxicos. A cavidade bucal é constantemente banhada de saliva, um fluido biológico com potente atividade antifúngica e bacteriana. Com o recente progresso na análise do proteoma salivar, o número de proteínas salivares identificado aumentou consideravelmente. A Histatina 5 gerada proteoliticamente a partir de Hst-3, durante a maturação dos grânulos nas glândulas salivares das parótidas tem sido extensivamente estudada devido a sua maior ação fungicida sua notável ação contra a C. albicans. Métodos baseados em medidas da atividade metabólica e viabilidade celular, como o ensaio de redução do sal XTT (hidróxido de 2,3-bis (2-metoxi-4-nitro-5-sulfofenil) -5 - [(fenilamino) carbonil] -2H-tetrazólio ) e contagem de unidades formadoras de colônia (UFC) tem sido utilizados para a avaliação de novos medicamentos capazes de inibir a formação do biofilme. Por serem feitos separadamente, esses ensaios demandam tempo, alto custo e variabilidade entre as amostras. Assim, este estudo teve como objetivo avaliar inicialmente, i) os efeitos do sal XTT e os demais compostos utilizados para realizar o ensaio de redução de XTT, sobre a viabilidade celular dos biofilmes de C. albicans e S. Mutans; ii) avaliar o potencial da histatina...(Resumo completo clicar acesso eletrônico) / Abstract: Candida albicans, present in oralbiofilms, is primarily responsible for denture stomatitis. Usually the infection is asymptomatic, but when signs and symptoms are present it can cause mucosal bleeding, swelling, burning or other painful sensations. Topical drugs such as miconazole and nystatin have been used, however, the diluent effect of saliva, the tongue and oral muscles movements reduce the dose of these agents to subtherapeutic concentrations, besides the high rate of recurrence of the infection. Thus, it is important to search for new antifungals, which are efficient and non-toxic. The oral cavity is constantly in presence of saliva, a biological fluid with potent antifungal and bacterial activity. With the recent progress in analysis of saliva proteome, the number of identified salivary proteins has increased considerably. The histatin-5 generated proteolytically from Hst-3, during maturation of the granules in the salivary glands of the parotid has been extensively studied due to their greater fungicidal action his remarkable action against C. albicans. Methods based on measurements of metabolic activity and cell viability as reduction assay salt XTT (2,3-bis hydroxide (2-methoxy-4-nitro-5-sulfophenyl) -5 - [(phenylamino) carbonyl] - 2H-tetrazolium) and counting of colony forming units (CFU) have been used for the exploration of new drug potential on inhibitory development of biofilm. The associations between the metabolic activities experiments with counting CFU are labor-intensive processes that need to be done separately. This study aimed to evaluate initially i) the effects of XTT salt and other compounds used to make the XTT reduction assay on cell viability of biofilms of C. albicans and S. mutans; ii) evaluate the potential of histatin 5 in protecting the human oral epithelium against C. albicans and iii) identify the heterotypic complexes formed between the histatin 5, a natural...(Complete abstrat electronic access below) / Doutor

AIM: The aim of this preliminary clinical study is to compare the stress level of non-hypertensive and hypertensive subjects by measuring changes in Chromogranin A (CgA) level in saliva before and after non-surgical periodontal treatment, scaling and root planing (SRP), subjects and to determine if the dental treatment affects the patient’s stress level. We will also measure the changes in arterial blood pressure before and after non-surgical periodontal treatment. Finally, compare if the duration of treatment affects the CgA level and blood pressure between non-hypertensive and hypertensive subjects. MATERIALS AND METHODS: Twenty patients participated in the study and only 17 evaluated. Four hypertensive patients and 13 non-hypertensive patients. Blood pressure was measured and saliva samples were collected at consultation visit (T0) and before (T1) and after (T2) non-surgical periodontal treatment (SRP). Duration of treatment was recorded. RESULTS: Concentration of CgA (pmol/ml) in the hypertensive group between T0 – T2 and T1 – T2 was a decrease of 15% and 46.5% respectively. The non-hypertensive group a decrease of 71% and 64.4% respectively. For the whole population, there was a significant decrease in CgA concentration between T0 – T2 (p-value = 0.046) and T1 – T2 (p-value = 0.032) with no statistical significance between T0 – T1 (p-value =0.873). No significant difference in change of blood pressure. CONCLUSION: Within the limitations of this study, there was no significant difference in blood pressure measurements. Concentrations of CgA decreased significantly after SRP compared to before SRP in all groups. A larger sample size is needed in the future.

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 composição inorgânica e análise proteômica da saliva total de indivíduos com FC e identificar biomarcadores para uso no diagnóstico da doença. Foram coletadas amostras de saliva de habitantes da região Centro Oeste do Brasil: 12 indivíduos homozigotos para a mutação ?•F 508 (4 mulheres, 8 homens), 12 heterozigoto para ?ýF 508 (5 mulheres, 7 homens), 13 indivíduos com FC com mutações não identificadas (6 mulheres, 7 homens), 8 indivíduos com diagnóstico duvidosos para FC ( 5 mulheres, 3 homens) e 43 indivíduos saudáveis (23 mulheres e 20 homens). Indivíduos com dúvida no diagnóstico para FC ou que não cumpriram os requisitos para compor o grupo controle foram excluídos das análises. Os teores dos elementos traço Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, Se, Si, Sr, Ti, V e Zn na saliva foram avaliados por espectrometria de massa com plasma de argônio acoplado indutivamente (ICP-MS), espectrometria de emissão óptica com plasma de argônio acoplado indutivamente (ICP-OES) e espectrometria de absorção atômica (AAS). O perfil protéico foi estudado por eletroforese em gel de poliacrilamida na presença de Sodium Dodecyl Sulfate (SDS-PAGE), por eletroforese bidimensional (2-DE) e análise de bases peptídicas por espectrometria de massa (MS/MS). Os elementos Na e K apresentaram, em média, teores mais elevados, enquanto, V, Cr e Se menos elevado quando comparados a indivíduos saudáveis, o elemento As foi detectado apenas no grupo de indivíduos saudáveis (p<0,05). Nas análises por eletroforese, o grupo com FC apresentou uma banda nítida de massa molecular de 38 kDa, não visualizada nos indivíduos sem a doença. A espectrometria de massa identificou a uma imunoglobulina (IgA), a qual esta visivelmente expressa nos indivíduos com FC. Existe diferença significante entre a saliva de indivíduos com FC e às de indivíduos saudáveis. Foi também identificado diferenças no perfil protéico. Com os resultados deste trabalho podemos inferir que a saliva total estimulada é uma fonte potencial para estudos que possam corroborar no desenvolvimento de um método de diagnóstico precoce e preciso da FC. ______________________________________________________________________________________ ABSTRACT / Cystic Fibrosis (CF) is an autossomic recessive lethal inherited disease that presents certain difficulties for an early and accurate diagnosis. Due to its pathological character this disease assumes great importance and early diagnosis is of paramount importance for a good prognostic. The objective of this study was to determine the inorganic composition and the proteomic analysis of stimulated whole saliva obtained from CF and identify biomarkers for CF diagnosis. Samples were collected from individuals living in the Brazilian West Central Region: 12 homozygous for mutation ?•F 508 (4 females; 8 males); 12 heterogeneous for mutation ?•F 508 (4 females; 8 males); 13 with unidentified CF mutations (6 females; 7 males); 8 with doubtful CF diagnosis (5 females; 3 males); and 43 healthy individuals (23 females; 20 males) for the control group. Samples from individuals with doubtful diagnosis as well as from those that did not fulfill the basic requirements to compose the control group were discarded. Concentration of trace elements Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, Se, Si, Sr, Ti, V e Zn were evaluated using mass spectrometer with inductively coupled argonium plasma (ICP-MS), optical emission spectrometer with inductively coupled argonium plasma (ICP-OES), and atomic absorption spectrometer (AAS). Protein profile was accessed by polyacrylamide gel electrophoresis 15% in presence of Sodium Dodecyl Sulfate (SDS-PAGE), by bidimensional electrophoresis (2D), and analysis of the peptide bases by mass spectrometry (MS) In every analyses, results obtained for CF individuals were compared to those for healthy subjects. Average concentration values for Na and K were higher in CF patients as compared to healthy individuals. In contrast, V, Cr, and Se, were lower. Element As was detected only in the healthy group (p<0,05). In the SDS-PAGE analysis CF patients presented a distinct band with molecular mass between 30 and 45 kDa not visualized in the healthy subjects. By 2D electrophoresis associated with mass spectrometry it was possible to identify a heavy chain immunoglobulin (C region) of Iga¥(IgA) clearly visible in CF patients. There were significant differences between saliva from healthy and CF individuals as well as in their protein profile. Results obtained in the present study indicate that stimulated whole saliva is a potential source for studies that may corroborate the development of an early and accurate screening method.

Intracellular signalling molecules create the signalling cascades which enable the transfer of the signal to the cell. In this work we have studied the influence of tick saliva on the cytokine production and the activation of signalling pathways in ionomycin stimulated murine mast cells. We found out that tick saliva inhibits production of several cytokines and affects two important signalling pathways in mast cells possibly involved in the regulation of cytokine induction.

It is not clear the action mechanism of insulin but it has been suggested that inositol phosphoglicans, such as myoinositol and D-chiro-inositol, can be important secondary messengers in insulin signal transduction. Although there are some studies linking a reduction in blood glucose levels in diabetic patients with the presence of these inositols in body secretions, there are not reports about the presence of these molecules in salivary composition. Thus, this study aimed to determinate the myoinositol and D-chiro-inositol salivary relation in children with type 1 diabetes and to compare the presence and concentration of these molecules with healthy children (non-diabetic). It has been selected and invited 45 volunteers of both sexes aged 3-12 years, 25 with decompensate type 1 diabetes and 20 healthy children. Saliva samples were collected and centrifuged. The supernatants were separated, purified and lyophilized. The identification of myoinositol and D-chiro-inositol were carried out by means of high-performance liquid chromatography (HPLC). The results showed that children with type 1 diabetes have a lower concentration of D-chiro-inositol and a higher concentration of myoinositol than healthy children. Consequently, the myo/chiro-inositol rate was higher in type 1 diabetes children and there is a correlation between the rate and type 1 diabetes incidence. In conclusion, our data suggests that myoinositol and chiroinositol found in the saliva of children with type 1 diabetes may influence in metabolic control and plays an important role as markers of type 1 diabetes. / A Diabetes mellitus é uma doença de causa múltipla, ocorrendo quando há falta de insulina ou quando a mesma não atua de forma eficaz, causando um aumento da taxa de glicose no sangue (hiperglicemia). Ainda não se sabe precisamente o mecanismo de ação da insulina, alguns trabalhos sugerem que pode ser possivelmente mediado através do fosfoglicano inositol (IPGs), cujas algumas formas foram identificadas como: mioinositol e D-quiroinositol. Há estudos que relacionam a redução da glicemia em indivíduos diabéticos com o aparecimento desses inositóis nas secreções corpóreas, embora ainda não haja registro de identificação dessas moléculas na composição salivar. O objetivo deste estudo foi determinar a relação salivar do mioinositol e quiroinositol em crianças com diabetes tipo 1 e comparar a presença e concentração dessas substâncias com um grupo de crianças sadias (não diabéticas). Um total de 45 (quarenta e cinco) voluntários, 25 com diabetes tipo 1 descompensados e 20 sadios (não diabéticos), de ambos os sexos, com idades de 3 a 12 anos, foram selecionados e convidados a participar do estudo. Amostras de saliva foram coletadas e centrifugadas. Os sobrenadantes foram separados, liofilizados e purificados. Logo em seguida, foram analisados por cromatografia líquida de alta eficiência (HPLC) para a identificação do mioinositol e quiroinositol. A partir dessa análise, foi observado uma menor concentração de quiroinositol (p=0,001, Kruskal- Wallis ANOVA seguido por método de Dunn’s) e uma maior da concentração de mioinositol (p=0,001, Kruskal- Wallis ANOVA seguido por método de Dunn’s) nas crianças afetadas em comparação com as crianças saudáveis. Os pacientes com diabetes tiveram a razão mio/quiroinositol maior que do grupo controle (p=0,001, Kruskal- Wallis ANOVA seguido por método de Dunn’s) e apresentaram uma correlação entre sua proporção o DM1(p= 0,001). O resultado desse estudo sugere que o mioinositol e o quiroinositol encontrado na saliva de crianças com DM1 podem influenciar no controle metabólico e desempenhar um papel de marcadores da DM1.
