Association between nutritional values of hays fed to horses and sensory properties as perceived by human sight, touch and smell
2019
International audience; Although hay is the foundation of most equine diets, horse owners rarely ask for biochemical analysis and the routine practice is to choose hay based on its 'perceived' nutritional value. The present study aimed at exploring the relationship between sensory properties as perceived by sight, touch and smell, and the nutritional value of hay measured by biochemical analysis using a 'free sorting task' method. Fifty-four non-expert participants were asked individually to: (1) observe 21 hays samples, (2) group together hays that they perceived as similar for each of the three modalities (hay appearance, odour or texture) and (3) characterize each formed group with a max…
In vivo sodium release and saltiness perception in solid lipoprotein matrices. 2. Impact of oral parameters
2012
This study aimed to investigate the relationships between sodium release, saltiness, and oral parameters during the eating of lipoprotein matrices (LPM). Sodium release and saltiness relative to 10 LPM were recorded during normal mastication by five subjects with differing oral parameters (chewing efficiency and salivary flow rate). The LPM samples varied in composition (dry matter, fat, salt, and pH levels) and represented a broad range of hardness. Mastication was recorded using electromyography simultaneously with sensory assessment. Differences in chewing behavior could explain most of the variability in sodium release and saltiness among subjects. Subjects with a higher chewing force a…
The human hepatic asialoglycoprotein receptor is a target antigen for liver-infiltrating T cells in autoimmune chronic active hepatitis and primary b…
1990
Autoantibodies to the human hepatic asialoglycoprotein receptor have been found in nearly 50% of the sera of patients with autoimmune chronic active hepatitis and in 15% of patients with primary biliary cirrhosis. In this study we demonstrate that the human hepatic asialoglycoprotein receptor is also a target antigen for T cell-mediated immune responses. Peripheral blood lymphocytes of 37% (7 of 19) of patients with autoimmune chronic active hepatitis and 33% (2 of 6) of patients with primary biliary cirrhosis showed a proliferative response to highly purified human hepatic asialoglycoprotein receptor, whereas no proliferation was found with peripheral blood lymphocytes of patients with chr…
Influence of repeated consumption of beverages containing sucrose or intense sweeteners on food intake.
2003
To investigate the influence of ingestion of beverages with sucrose or with intense sweeteners on food intake (FI) and on hunger ratings in before and after a month of daily consumption of beverages.Experimental study.Department of Physiology, University Hospital, Dijon, France.In all, 12 men and 12 women, aged 20-25 y.Four beverages contained either sucrose (E+:100 g/l, 1672 kJ) or intense sweeteners (E-: null energy content) and were flavoured with either orange (O) or raspberry (R). FI was measured in the lab during two 2-consecutive-day periods, carried out on 2 successive weeks (session 1). The subjects drank 2 l of either E+ or E- beverages on the first day of both weekly periods, acc…
Prolonged in vitro exposure to white wines enhances the erosive damage on human permanent teeth compared with red wines.
2009
Abstract The aim of this in vitro study was to determine and compare the erosive potentials of red and white wines, exerted on enamel surfaces prepared from extracted human permanent teeth. European wines (50 red, 50 white wines) from different regions were purchased, and the pH values were measured. Eight wines with different pH values were selected. Enamel samples with an average surface area of 25 mm 2 were prepared from 25 extracted permanent teeth from male and female patients aged 40 to 65 years and incubated with wines for up to 24 hours; the amounts of released calcium were determined colorimetrically, and mean surface roughness was measured with a profilometer. A quantitative eleme…
Forensic microbiology applications: A systematic review.
2019
Abstract According to the Human Microbiome Project (HMP), a healthy human body contains ten times more microbes than human cells. Microbial communities colonize different organs of the body, playing fundamental roles both in human health and disease. Despite the vast scientific knowledge of the role of microbial communities in a living body, little is known at present about microbial changes occurring after death, thus leading many authors to investigate the composition of the thanatomicrobiome and its potential applications in the forensic field. The aim of the following review is to provide a general overview of the advances of postmortem microbiology research, mainly focusing on the role…
A retrospective study of the prevalence and characteristics of dens invaginatus in a sample of the Turkish population.
2012
Objective: The purpose of this study was to assess the prevalence of dens invaginatus and to classify the types of dens invaginatus in a sample of the Turkish population.. Study Design: A retrospective study was performed using periapical and panoramic radiographs of 5355 patients who presented to the Department of Oral Diagnosis and Radiology at the Ondokuz Mayıs University Dentistry Faculty between January 2009 and December 2010. Maxillary and mandibular anterior teeth were evaluated for the presence and characteristics of dens invaginatus. Statistical evaluation of the presence of dens invaginatus related to gender was performed by the Pearson chi-squared test. Results: Dens invaginatus …
Associations between polymorphisms in the thymidylate synthase gene, the expression of thymidylate synthase mRNA and the microsatellite instability p…
2004
Microsatellite instability (MSI) is a characteristic feature of up to 15% of colorectal cancers (CRC) and is associated with better response to adjuvant chemotherapy with 5-fluorouracil (5-FU). In this study we have investigated the association between the MSI status and the mRNA expression as well as the polymorphisms of the cellular target of 5-FU therapy, thymidylate synthase. Polymorphisms in the 3'- and the 5'-UTR of the TS gene were determined by a PCR assay in 53 colorectal cancer tissues. TS mRNA was quantified by real-time RT-PCR. Data were correlated with the MSI phenotype. There was neither a significant correlation between the polymorphisms in the TS gene and the MSI phenotype n…
EchoScopy in scanning abdominal diseases: initial clinical experience.
2014
Background and Aims: The introduction of a new type of small handheld ultrasound device brings greater portability and affordability. The basic ultrasound approach with these handheld devices has been defined by European Federation of Societies of Ultrasound in Medicine and Biology (EFSUMB) as “EchoScopy”. The current study aimed to assess the image quality, indications and limitations of a portable pocket “EchoScope” compared with a high-end ultrasound system in abdominal diseases. Methods: 231 consecutive patients were included in this study. Physician A performed ultrasound examinations with a high-end ultrasound system (HEUS), then physician B performed the same ultrasound examination u…
Normal intestinal dietary fat and cholesterol absorption, intestinal apolipoprotein B (ApoB) mRNA levels, and ApoB-48 synthesis in a hypobetalipoprot…
1997
Abstract The purpose of this study was to characterize intestinal apolipoprotein B (apoB) metabolism in subjects with familial hypobetalipoproteinemia (FHBL), where segregation analysis supports linkage to the apoB gene but no apoB truncations are present. We investigated cholesterol and fat absorption, intestinal apoB mRNA synthesis and editing, as well as apoB-48 synthesis. Plasma triglycerides (TG) and retinyl palmitate in the chylomicron fractions were analyzed after 12 hours of fasting and then repeatedly for 14 hours after ingestion of a vitamin A—containing high-fat meal. Cholesterol absorption was assessed using a dual stable-isotope method. Mean peak times and concentrations and ar…
