Full textIn the case of a hospitalization, bedsores are a major issue regarding the comfort of the patient as well as economical reasons. Due to the aging population, the nurses are more and more confronted to prevention and treatment of bedsores. Thus, prevention is now considered as essential in hospitals. It must be noted that in matter of bedsores, there exist only a few specialized products which efficiency has been proved. Therefore, in association with RIVADIS Laboratory, we planed to work on a galenic formulation which contains a combination of innovative natural active. A complete compilation of specialized publications on this topic has been realized in order to fully understand all the risk factors. Then, thanks to an extensive research, we identified the plants and molecules that could be used as actives for the prevention and/or treatment of this pathology. We focused on their anti-inflammatory, healing, antioxidant and bacterial anti-adhesive properties. The two best actives thus obtained are apple pectin and dry Centella asiatica L. extract, they present significant results on at least three of the four wanted properties. Studying the combined effects of these two actives even showed a synergy on bacterial anti-adhesive property. They have then been incorporated in a galenic formulation that makes the massage as easy as the one allowed by already commercialised oils and enables the incorporation of hydrophilic actives

Full textGrowing studies on host-associated microbiomes are highlighting the important role of microbes in the development, health and fitness of their hosts. This might be particularly true in remote and extreme environments, such as the Antarctic ecosystem, where the host and its microbiome could evolve together establishing peculiar and close interactions. This study aims: i) to investigate the biodiversity of microbiomes of different Antarctic invertebrates, ii) to explore the potential sources of the host-associated microorganisms by comparing them with microbial communities inhabiting the surrounding sediments, and iii) to verify the role of environmental setting in shaping their taxonomic composition. Results revealed that microbiomes of Antarctic polychaetes (Leitoscoloplos geminus, Aphelocaeta palmeri, Aglaophamus trissophyllus) showing significant variability among individuals, but that both intra-specific and inter-specific core microbiomes contribute for a significant fraction to the whole microbial assemblage. Bacteria associated with polychaetes were completely different from those in the surrounding sediments, suggesting a potential vertical transmission or the presence of different adaptative/selective conditions of the two “habitats”. Multiple factors (i.e., not only environmental factors but also biological ones such as physiological state and feeding habits) can influence to different extent the taxonomic composition of microbiomes associated with Antarctic polychaetes. In the Antarctic sea star Odontaster validus, the geographic location was identified as the main factor influencing the taxonomic composition of microbiomes, but this was not a general rule. In fact, high similarities were found among microbiomes of individuals collected in different locations, suggesting the presence of other drivers able to select similar microbial communities. The presence of exclusive bacterial families in sea-star microbiomes suggests a potential horizontal transmission of bacterial taxa, probably acquired through different feeding habits that the sea star might have developed in the different basins. This PhD thesis provided new information on Antarctic microbiomes, highlighting a strong variability of their composition and complexity of the relationships with the investigated hosts, potentially due to, besides environmental settings, also to hosts’ biological features.

Full textIt is now admitted that the gut microbiota plays a key role in the health status of its human host. It is indeed fully recognized as an endocrine organ producing biologically active molecules which are integrated within human metabolism. However, comprehensive studies characterizing host-gut microbial metabolic relationships remain scarce. Numerous factors have been shown to exert a modulatory impact on the gut microbiota. Notably, diet is supposed to be a major driver, but the relationships between usual diet and the gut microbiota are not fully elucidated yet. Furthermore, many studies have suggested the implication of the gut microbiota in a wide range of disease states, such as gastrointestinal, cardio-metabolic, neuropsychiatric, etc. disorders. Thus, understanding the factors influencing the gut microbiota constitutes an active area of research. In this context, we adopted an epidemiological approach to investigate one of the largest population-based samples so far (Milieu Intérieur population, N=1,000). We notably assessed the associations between gut microbiota composition on one hand and the systemic metabolism and the usual diet of the host on the other. Finally, in the NutriNet-Santé cohort (N≈160,000), we investigated the associations between the intake of dietary fibers and the risk of a variety of chronic diseases, and described how dietary fibers are associated with the gut microbiota.Overall, our results suggest that gut bacterial features are specifically associated with certain components of the systemic metabolism of the host, and we hypothesize a substantial role of the gut-kidney axis. Besides, negative associations between food items for which a limited consumption is generally recommended (i.e. processed foods) and gut microbial features were detected. Additionally, we confirm robust inverse associations between the consumption of dietary fibers and several major chronic diseases. Mounting evidence suggests that such effects could be mediated by the gut microbiota

Full textThis research is focused on the performance evaluation of a new system configuration of combined biological reactors, treating domestic wastewater till tertiary level. The pilot scale proposed system had a total useful volume of 71,48 liters. This new configuration involves three types of superposed reactors: an Upflow Anaerobic Sludge Blanket reactor; an aerobic fixed film mobile bed reactor (fed with pure oxygen); and a fixed film mobile bed reactor at anoxic environment. The support material used inside the fixed film mobile bed reactors was wood made grooved dowels. The main purposes of this work are to evaluate the systems general performance regarding COD and nitrogen removal, and the microbial associations inside the reactors. It reached quite satisfactory results regarding COD and nitrogen removal when the total hydraulic retention time (HRT) was around 20 hours, including the clarification zone volume (94,6 % for the COD; and 96,7 % for the TKN-N, whit nitrate formation below 10,0 mgN-NO3-/l). HRTs from 5 to 20 hours were studied. The microbial associations were present in large number, with a great diversity and high specific activities at the different environments, confirming the good results obtained and the suitable environment provided for the growth of the different populations inside the three reactors. The idealization of this treatment system has the goal to treat domestic wastewater from small to large communities till tertiary level, in compact treatment plants, due to the possibility of constructing several modules of the system.

Emerging pollutants are consist of organic pollutants, industrial chemicals, pharmaceuticals and personal care products (PPCPs) and endocrine interfering substances. Traditional wastewater treatment process has low efficiency of removing emerging contaminants , such that the pollutants can easily enter the aquatic environment, and may result in the impact of environmental ecosystem . In Taiwan, antibiotics is the most widely use of PPCPs, among which the antibiotics for animals is widespread. In order to understand the impact of waste water discharges to the environment from pigs farms in Taiwan, levels of tetracycline and sulfonamide antibiotics in wastewater, and antibiotic resistant microorganisms in the environment were determined, and the assess of its impact on the environment system was addressed. Samples including swine wastewater, upstream and downstream of the river surface water relative to the site where wastewater discharged, soils of the riverbank, sludge and water of adjacent well were collected and analyzed. The results indicated that higher percentage of tetracycline and sulfonamide resistant microorganisms present in the wastewater. The number and percentage of the antibiotic resistant bacteria in the downstream river water was significantly higher than there of upstream river water, These resistant microorganisms exhibited higher antibiotic resistance gene loadings and multiple drug resistance. The denaturing gradient gel electrophoresis (DGGE) was used to analyze the microflora 16S rDNA and tetracycline resistance gene tetW diversity, and the results indicated that although microflora of each sample with high diversity, tetW gene can be classified into only 2 groups of very high similarity in these sequences, suggesting that horizontal gene transfer the resistance gene is likely to occur from microorganisms in the wastewater of pig farms to the microorganisms in river water. Isolates of sulfonamide resistant microorganisms from each sampling site also showed substantial phylogenetic divergence with high nucleotide identity of resistance genes. The pig farm wastewater and downstream river water detected a higher number of class 1 integrons, and three types of resistance genes embedded. In summary, the results show antibiotic resistant microorganisms in the swine wastewater discharged into the water environment can increase the number of antibiotic resistant microorganisms in the environment, expand the size and variety of gene pool of the antibiotic resistant genes in the overall environment. It may have an effect on the environmental ecosystem due to bioaccumulation or transfer to potential pathogens, and contribute to a potential risk of harm to human health and ecological.

Literatures have consistently demonstrated associations between exposures to microbial agents in built environments with increasing risk of reporting respiratory diseases, mostly based on measurements of single or selected microbial agents. However, in reality, environmental microbes (e.g. fungi and bacteria and other allergens) are co-existed in any environments at all times. Therefore, study including concurrent assessment of related bioaerosols becomes essential to elucidate their individual or synergistic roles deriving at corresponding health outcomes of concerns. The aims of this study with children aged 6 to 8 is to investigate the individual and combined effects of concurrent exposures to various microbial agents, such as airborne fungal spores, viable fungi, viable bacteria, house dust associated fungal (1→3)-β-D-glucan and bacterial endotoxin, as well as house dust mite allergens, on reporting respiratory or allergic symptoms and diseases. Home characteristics are also analyzed for associations with quantitative microbial levels when appropriate to examine the potential and effective surrogates reflecting microbial exposures for prevention. Results indicate that fungal spores and Der p1 are the significant major microbial agents related to the studied health outcomes. Moreover, the moisture content of building materials (>100%), indoor and outdoor 24-hrs average temperature (<27.13℃ and <27.58℃, respectively), indoor 24-hrs average relative humidity (>63.65%), presence of irritant smells as well as higher human density can be considered as alternative or surrogate environmental indicators without actual maneuver of real sampling and analytical activity for environmental microbes. Preventive measures and priority of remedial actions can therefore be planned accordingly.
