This paper is concerned with the design and the analysis of some nonlinear control strategies for a lactic acid production in the context of a continuously stirred tank reactor for which dynamical kinetics are strongly nonlinear and not exactly known. Since in a lactic acid fermentation process the main cost of raw material comes from the substrate and nutrient requirements, some multivariable ...

Effects of an 18-month treatment with a moderate, chronic caloric restriction (CR) or an oral supplementation with resveratrol (RSV), a potential CR mimetic, on cognitive and motor performances were studied in non-human primates, grey mouse lemurs (Microcebus murinus).Thirty-three adult male mouse lemurs were assigned to three different groups: a control (CTL) group fed ad libitum, a CR group f...

Genetic selection and better control of the environment of the pigs have resulted in increased production levels concerning both reproduction and growth. Such high performances imply high physiological demands that may deteriorate health and welfare. The aims of this paper are to review the physiological challenges that pigs are facing, to identify possible consequences on health and welfare, t...

Nutritional assessment in older people to detect malnutrition or risk of malnutrition is essential to avoid adverse nutrition-related outcomes. Poor nutritional status appears to be a major contributing factor for poor prognosis in malnourished individuals. Nowadays, nutritional assessment is considered to be one of the domains which should be evaluated in comprehensive geriatric assessment (CG...

The impact of nutritional status on survival among elderly esophageal squamous cell carcinoma (ESCC) patients undergoing radiotherapy is unclear. In this study, we aimed at validating the performance of the geriatric nutritional risk index (GNRI) in predicting overall survival time in elderly ESCC patients with radiotherapy. A retrospective cohort study was conducted on 239 ESCC patients aged 6...

BACKGROUND Age-related losses of muscle mass, strength, and function (sarcopenia) pose significant threats to physical performance, independence, and quality of life. Nutritional supplementation could positively influence aspects of sarcopenia and thereby prevent mobility disability. OBJECTIVE To test the hypothesis that a specific oral nutritional supplement can result in improvements in mea...

A multistressor study was conducted to investigate interactive effects of nutritional status and salinity on osmoregulation of juvenile white sturgeon. Our hypothesis was that lower nutritional status would decrease the salinity tolerance of juvenile white sturgeon. A four-week feed restriction (12.5%, 25%, 50%, 100% of optimum feeding rate: OFR defined as the rate (% body weight per day) at wh...

INTRODUCTION Assessment of pregnant mothers for nutritional status is a neglected intervention. In Kaabong Hospital, nutritional status of pregnant mothers was not assessed during antenatal care (ANC) visits. A quality improvement (QI) project was initiated to increase nutritional assessment using midupper arm circumference (MUAC) among pregnant mothers during ANC visits from 0 to 90% between A...

Objectives: The aims of this work were (a) to provide a detailed description of the association between nutritional (Mini Nutritional Assessment; MNA®) and functional status in a sample of older adults receiving home care, using both questionnaireand performance-based functional methods, and (b) to investigate the impact of different MNA subscales on this association. Design: Multi-centre, cros...
