Cassava starch processing at small scale in North Vietnam
2008
International audience; In Northern Vietnam, small-scale cassava starch processing is conducted in densely populated craft villages, where processors face difficulties to expand their activities. Three different processing systems were studied among a cluster of three communes in the Red River Delta, producing up to 430 t of starch (at 55% dry matter) per day. The first system, type A, is a cylindrical rasper and a manual sieve, the second, type B, is a cylindrical rasper and stirring-filtering machine and the third, type C, used equipment for both the rasping and filtering stages. Moisture, starch, crude fibers and ash content analysis were carried out on samples collected from the A-B-C m…
Biogenic amines in fermented foods
2010
Food-fermenting lactic acid bacteria (LAB) are generally considered to be non-toxic and non-pathogenic. Some species of LAB, however, can produce biogenic amines (BAs). BAs are organic, basic, nitrogenous compounds, mainly formed through decarboxylation of amino acids. BAs are present in a wide range of foods, including dairy products, and can occasionally accumulate in high concentrations. The consumption of food containing large amounts of these amines can have toxicological consequences. Although there is no specific legislation regarding BA content in many fermented products, it is generally assumed that they should not be allowed to accumulate. The ability of microorganisms to decarbox…
Bis(hydroxyphenyl)methane-bisphenol F-metabolism by the HepG2 human hepatoma cell line and cryopreserved human hepatocytes
2011
author cannot archive publisher's version/PDF; International audience; Bisphenol F (BPF) is present in the environment and as a contaminant of food. Humans may, therefore, be exposed to BPF, and an assessment of this risk is required. BPF has been shown to have genotoxic and endocrine-disruptor properties in a human hepatoma cell line (HepG2), which is a model system for studies of xenobiotic toxicity. In this study, we investigated the ability of HepG2 cells to biotransform BPF, because metabolism may affect the observed effects of BPF, and we compared this metabolic capacity with that of human hepatocytes. Cells were incubated for 24 hours with [(3)H]-BPF. The culture medium was then conc…
The need for internships and school practices as a method of bridging the gap between education and industry in Romania
2017
Abstract This paper presents the current situation of school practice and internships as ways of reducing the gap between the labor market and education. In the first part, there is highlighted the current situation of Romania comparing with other European countries when it comes about graduates finding a job in their field of studies. Among the biggest issues encountered by a young graduate we see that "Lack of experience” play a big role in not finding a proper job in our country after graduation. So the need to reduce this problem is vital in order to ease finding a job in the studies areas for graduates. A list of advantages is presented to encourage internships/school practice among th…
Clarifying Communication Professionals’ Tasks In Contributing To Organizational Decision Making
2017
The purpose of this paper is to discuss the tasks through which communication professionals and public relations contribute to organizational decision making. In-depth interviews were conducted with Finnish public relations professionals about how they contribute to organizational decision making. The findings provide a rich picture of the tasks in relation to this. The results show that public relations professionals contribute to organizational decision-making processes by nine different tasks. Furthermore, the results indicate that during an organizational decision-making process, professionals switch from one task to another over time, and work simultaneously on several tasks. This pape…
The Lipid-Sensor Candidates CD36 and GPR120 Are Differentially Regulated by Dietary Lipids in Mouse Taste Buds: Impact on Spontaneous Fat Preference
2011
BACKGROUND: Recent studies in rodents and humans suggest that the chemoreception of long-chain fatty acids (LCFA) in oral cavity is involved in the spontaneous preference for fatty foods and might contribute to the obesity risk. CD36 and GPR120 are LCFA receptors identified in rodent taste bud cells. The fact that CD36 or GPR120 gene inactivation leads to a decrease in the preference for lipids raises the question of the respective role(s) played by these gustatory lipid-sensor candidates. METHODOLOGY/PRINCIPAL FINDINGS: Using a combination of biochemical, nutritional and behavioural studies in wild-type, CD36(+/-)and CD36(-/-) mice, it was found that: 1°) CD36 and GPR120 display different …
CD36 and taste of fat.
2012
Purpose of review This review explores the recent literature on the role of CD36 in the taste of fat, eating behavior and obesity risk in rodents and humans. Recent findings During the last decade, evidence was accumulated supporting the existence of a taste of fat responsible for the spontaneous preference for lipid-rich foods. Surprisingly, the multifunctional membrane-associated protein CD36 appears to play a significant role in this system in rodents. Recently, another plausible gustatory lipid sensor, the GPR120, was also identified in mice, revealing that the mechanism involved in oral fat detection is more complex than initially expected. Interestingly, lingual CD36 and GPR120 displa…
Ca2+ signaling in taste bud cells and spontaneous preference for fat: Unresolved roles of CD36 and GPR120
2013
Recent compelling evidences from rodent and human studies raise the possibility for an additional sixth taste modality devoted to oro-gustatory perception of dietary lipids. Understanding the mechanisms underlying oro-gustatory detection of dietary fat is critical for the prevention and treatment of obesity. A number of studies have suggested that lingual CD36, a glycoprotein, highly expressed by circumvallate papillae of the tongue, is implicated in the perception of dietary fat taste. G protein-coupled receptors (GPCRs) are important signaling molecules for many aspects of cellular functions. It has been shown that these receptors, particularly GPR120, are also involved in lipid taste per…
Lipid-mediated release of GLP-1 by mouse taste buds from circumvallate papillae: putative involvement of GPR120 and impact on taste sensitivity
2012
Glucagon-like peptide-1 (GLP-1) signaling modulates sweet-taste sensitivity in the mouse. Because circumvallate papillae (CVPs) express both GLP-1 and its receptor, a local regulation has been suggested. However, whether dietary lipids are involved in this regulation, as shown in the gut, is unknown. By using a combination of biochemical, immunohistochemical, and behavioral approaches, the present data i) confirm the role of GLP-1 signaling in the attraction for sucrose, ii) demonstrate that minute quantities of long-chain FAs (LCFAs) reinforce the attraction for sucrose in a GLP-1 receptor-dependent manner, iii) suggest an involvement of the LCFA receptor GPR120 expressed in taste buds in …
CEO’s Letter Accompanying the Report on Corporate social Responsibility of Canadian Listed Firms: An Analysis of the Content and the Links with Some …
2016
International audience; The disclosure of Corporate Social Responsibility (CSR) by Canadian firms is not mandatory. This provides an ideal context to describe the nature of what is being freely disclosed by large firms and to study the firms’ characteristics which lead to such disclosure. We searched all TSX listed firms to find those which disclose a CSR report accompanied by a letter from the CEO. In the end, we study 89 CEO’s letters; that is, all the firms disclosing both a CSR report and a CEO’s letter. We first looked at the nature of the elements disclosed. We classified them in 3 categories: (1) actual accomplishments in the field of CSR, (2) values and (3) future objectives. The «a…
