Evaluation of carotenoids and furosine content in air dried carrots and parsnips pre-treated with pulsed electric field (PEF)
2019
Carrot and parsnip slices were subjected to hot drying at 50, 60 and 70 °C with or without pulsed electric field (PEF) pre-treatment at 0.9 kV/cm and 1000 and 10,000 pulses. The effect of drying on processed samples was assessed by analysis of carotenoids, the furosine value, total phenols and the Whiteness Index (WI). PEF pre-treatment is effective in reducing drying times, but the degree of cellular breakdown makes the compounds more susceptible to chemical and enzymatic reactions. In our condition PEF pre-treatment increased the carotenoid degradation and promoted the Maillard reaction above all at the highest temperature of 70 °C. The assessment of carotenoid stability, together with th…

Evaluation of Changes in Gut Microbiota in Patients with Crohn’s Disease after Anti-Tnfα Treatment: Prospective Multicenter Observational Study
2020
Background: Crohn’s disease is believed to result from the interaction between genetic susceptibility, environmental factors and gut microbiota, leading to an aberrant immune response. The objectives of this study are to evaluate the qualitative and quantitative changes in the microbiota of patients with Crohn’s disease after six months of anti-tumor-necrosis factor (anti-TNFα) (infliximab or adalimumab) treatment and to determine whether these changes lead to the recovery of normal microbiota when compared to a control group of healthy subjects. In addition, we will evaluate the potential role of the Faecalibacterium prausnitzii/Escherichia coli and Faecalibacterium prausnitzii/Clostridium…
Interešu konflikts: Kipras un Piedņestras konfliktu salīdzinošā analīze.
2016
. Jau vairāk nekā četrdesmit gadus ilgā Kipras konflikta dēļ, salīdzinājumā ar Piedņestru Kiprai ir vairāk pieredzes mediācijā. Taču Kipras konfliktā gūtā pieredze var kalpot kā pozitīvu un negatīvu mediācijas piemēru kopums, jo abu konfliktu attīstības posmiem ir daudz kopīgu iezīmju. Abi konflikti ir piesaistījis daudzu valstu un starptautisko organizāciju uzmanību, tomēr ne vienmēr viņu iesaistīšanās ir palīdzējusi konflikta atrisināšanas procesā, dažreiz tā ir pat traucējusi konflikta risināšanā. Arī izmaiņas mediācijā dominējošo valstu lomās atspoguļo mainīgo starptautisko attiecību vidi. Konflikti Kiprā un Moldovā apdraud drošību Eiropaā, kas savukārt pierāda vajadzību pārskatīt pastā…
Evaluation économique de la prématurité : une première année de vie aux enjeux majeurs : le cas de la France
2016
This thesis focuses on a first economic assessment of prematurity in France. Prematurity is defined as occurring before 37 weeks of gestation. It is increasing in France and worldwide. If the issues of public health are already well identified, medical care and collective choices concerning prematurity matters also involve significant economic challenges. The first part of this thesis attempts to present the public health issues of prematurity and highlights the remaining efforts required to provide prevention in France. It then considers economic issues on the use of socially fairer resources dedicated to perinatal health in a context where current health expenditure is rising. Assessment …

GC sniffing analysis : olfactive intensity measurement by two methods
1995
The intensity perceived by sniffing after GC elution of six volatile compounds was measured by ten judges using two pieces of apparatus: a PC mouse which is moved on a 60-cm length scale and a rheostat apparatus which measures the finger span. The choice of the components mixed was influenced by purity, elution time, presence in food and known Steven's slopes. The histograms obtained by summing the responses (determined by measuring the areas under the peaks) of ten people show no significant differences between the two pieces of apparatus. Histograms realised in parallel by Charm analysis with three other judges showed great differences between subjects. However, the mean of the three Char…
Attitudes toward everyday odors for children with visual impairments: A pilot study
2010
The question of how the processing of stimuli from the external world is organized or reorganized when a sensory modality is altered or missing has been the subject of numerous studies, although the studies have mostly been on tactile and auditory abilities (Hatwell, 2003). In contrast, olfaction has been poorly investigated in people who are visually impaired, despite the increasing evidence that humans have a keen sense of smell (Schaal & Porter, 1991). Odors influence mood; well-being (Ehrlichman & Bastone, 1992); and social interactions, such as the choice of partners (Herz & Inzlicht, 2002). Emotional and social implications of odors go back to the earliest periods of development (Scha…
