Abstract:
L’étude de la lubrification orale devient une problématique actuelle pour l’industrie agroalimentaire. Les analyses quantitatives permettent de comprendre et d’anticiper des mécanismes physiologiques, tels que la prédiction des phénomènes d’astringence des produits alimentaires. L’astringence se manifeste par une diminution de la lubrification de la muqueuse orale après la consommation de produits d’origine végétale. Cependant, les recherches actuelles sur la lubrification orale s’appuient sur des matériaux synthétiques qui représentent mal les tissus buccaux. Elles négligent les interactions

Abstract:
This thesis studies how to increase the expected satiating ability in dairy products analyzing the effect of the incorporation of certain ingredients. The study of food reformulation with high expected satiating ability contributes to moderate size meal choice and to regulate food intake. In this thesis, two factors influencing the satiating ability perception of semi-solid foods have been mainly studied: a) the increase in oral processing time that produces prolonged orosensory signals, and b) the increase in protein content. The increase in oral processing time is produced by, for example,

Abstract:
The canine oral microbiota is poorly understood compared to that of humans. The aim of this work was to improve understanding of the canine oral microbiota. This was achieved by surveying the canine oral microbiota, determining coaggregation interactions between its members, and developing a laboratory microcosm. Bacteria were isolated from the dental plaque and saliva of dogs, and isolates were identified by comparative 16S rRNA gene sequencing. From 339 isolates, 84 phylotypes belonging to 37 genera were identified. Approximately half were identified to species level, and 28 % of these were

Manufacturers are under pressure to reformulate products to make healthier foods, without changing desirability or flavour. A better understanding of product breakdown under oral conditions is essential to structure novel products which are healthier without consumers noticing. In-vitro methods were developed to explore product behaviour when subject to a range of phenomena relevant to those in the mouth, with particular emphasis on lubrication behaviour. Polysaccharides common in food products were mainly used as model systems and salt release was studied in some systems. Three in-vitro syste

In vitro models of dental plaque are a valuable tool for understanding the development of plaque-related diseases and assessing potential treatments for these diseases. The main focus of this study was the development of an in vitro model to characterise the changes in bacterial populations from dental plaque associated with health to one associated with gingivitis. By emulating environmental conditions in the oral cavity associated with gingivitis it was possible to see changes in the oral microbiota associated with gingivitis.

Abstract:
Around half of oral bacteria have yet to be cultured, and their role in disease is therefore unknown. It is hypothesised that bacteria in biofilms have become dependent on growing in multi-species communities. TM7 phylum has no cultured representatives and some oral TM7 phylotypes have been associated with oral diseases such as periodontitis. The aims of this study were therefore to evaluate the ability of two model culture systems: Cooked Meat Medium and the Calgary Biofilm Device (CBD), to support the growth of mixed oral bacterial communities including uncultured bacteria, and to attempt to

Dipeptides can be absorbed into cells via the dipeptide transporter (which also transported tripeptides and dipeptide derivatives). The optimum conditions for measuring the inhibition of Gly-Pro uptake in Caco-2 cells were identified. A number of structure-activity relationships were identified. These included the effects of increasing the amino-acid chain-length, and the presence of a thiol or hydroxyl group in the side-chain increased IC50 while the presence of a hydroxyl group did not. The benzyl esters had lower or equal IC50 values compared to the parent dipeptides while the methyl esters

Abstract Desmoglein 3 (Dsg3) is an adhesion receptor in desmosomes, but relatively little is known about its role in cancer. In this study, the function of Dsg3 was investigated in oral squamous cell carcinoma (SCC) cell lines in vitro using locally established human leiomyoma tumor microenvironment (TME) matrices. Since Dsg3 has been identified as a key regulator in cell adhesion, we hypothesized that it may play a role in oral SCC cells adhesion and motility. Thus, one aim of the study was to explore this hypothesis by both gain and loss of function methods in four human buccal mucosa SCC Sq

Porcine buccal mucosa has been extensively used as in vitro model to study the permeability of drugs and assess their potential to deliver through buccal route. Porcine buccal mucosa is found to be very similar to human oral mucosa in structure and function. However, the in vitro permeation studies across porcine buccal mucosa show high variability which is mostly due to the various experimental and biological variables that are often overlooked while conducting such studies. The precise nature of the permeability barrier offered by the various tissue layers of buccal mucosa was investigated i

Abstract:
In vitro dissolution, release and permeation testing is a common practice during drug product research and development. These in vitro tests, if predictive, are referred to as biorelevant tests and can play diverse roles to facilitate and expedite product development in a cost effective manner. Oral transmucosal products (OTPs) are currently tested using compendial and modified in vitro tests which may or may not be good predictors of in vivo performance due to a lack of biorelevance. A critical need for a broadly applicable and biorelevant in vitro system for OTPs has been expressed in the li

Abstract Tumor associated macrophages (TAMs) are linked to the invasion of oral tongue squamous cell carcinoma (OTSCC). We modified THP-1 leukemia cells to M1 (inflammatory), M2 (TAM-like) and R848 (imidazoquinoline-treated) type macrophages in order to examine their interactions with OTSCC-cells (HSC-3) by using different kinds of in vitro migration and invasion models. We observed that interaction of TAM-resembling M2-type macrophages with HSC-3 cells induced invasion and migration, whereas the influence of M1 macrophages reduced them. Patient response to chemoradiotherapy is highly reliant

OBJETIVO: A etiologia das LNCs é complexa e não está totalmente esclarecida e parecem influir e interagir na sua formação fatores tão diversos como a concentração de tensões, a presença de ácidos de diversas origens e mecanismos tribológicos variados. O objetivo deste estudo in vitro foi avaliar se há diferenças na influência da tensão de tração, de compressão e da escovação na profundidade da lesão, microdureza e rugosidade do esmalte bovino submetido a desafio ácido. (O trabalho constituiu-se da avaliação dos danos ao esmalte bovino submetido a um desafio ácido erosivo e desafio abrasivo) co

Abstract:
A fototerapia laser (FTL) tem sido usada clinicamente para auxiliar na cicatrização de inúmeras doenças bucais, especialmente no tratamento de lesões ulceradas. Os mecanismos celulares através dos quais o laser é capaz de promover a bioestimulação não são completamente compreendidos. Dessa forma, o objetivo do presente estudo foi avaliar in vitro o efeito da FTL no comportamento de queratinócitos bucais no processo de cicatrização. Células epiteliais bucais (NOK-SI) foram cultivadas sob duas condições nutricionais: suplementadas com 10% de soro fetal bovino (FBS) e sob déficit nutricional (2%

Abstract:
Over the past few decades many researchers have investigated the utility of in vitro - in vivo correlations for the assessment of dosage forms. These investigations are, however, dependent on reproducible dissolution data and well conducted biostudies in order to establish meaningful and robust correlations. Despite the fact that the establishment of such correlations is perhaps idealistic, considerable interest has still been shown in this area of research.
