Effects of Environmental Lighting and Tryptophan Devoid Diet on the Rat Vaginal Cycle
1998
Cerebral serotonin level influences luteinizing hormone release and, consequently, ovulation. The present study evaluated the effects of precooked maize meal (polenta), a diet almost devoid of tryptophan the serotonin precursor on the alterations of the estrus cycle as measured by vaginal smears analysis in Wistar rats. Several conditions of environmental lighting were used in order to modify ovarian cycle: 1) natural alternating light/dark cycle; 2) continuous darkness; 3) continuous light by sodium steams: 4) continuous light by fluorescent neon tubes. Rats bred in continuous lighting showed estrus-proestrus rate significantly greater than rats bred in normal lighting or in continuous dar…
Knowledge, attitudes and self-reported practices of food service staff in nursing homes and long-term care facilities
2010
The aim of this study was to investigate knowledge, attitudes and practices of food service staff in nursing homes and long-term care facilities for the elderly in Sicily, Italy. Association with some demographic and work-related variables was also investigated. This survey provides information and outlines many complex questions concerning the basics of food hygiene. Education level, length of service in the employment and attending courses on food hygiene influenced the knowledge, attitudes and practices of food service staff. This study has evidenced the need for continuous training among food service staff regarding food safety in LTCF and nursing homes.
A review of the literature and a new classification of the early determinants of childhood obesity: from pregnancy to the first years of life
2007
Abstract From as early on as the development of the fetus, the risk of obesity can be evaluated. At the beginning of life, nutritional intake in man is controlled by innate biological systems and internal signals; and later on, the learning processes determine cognitive structures about food and nutrition, strongly influencing eating habits. It is important to identify all the factors that have an influence on childhood obesity and intervene with prevention programs. In this review, the databases “Pubmed" and “The Cochrane Library" were consulted to provide a review of recent literature (1982-2007) concerning childhood obesity. A particular importance is given to the influence exerted by th…
The antioxidant capacity of red wine in relationship with its polyphenolic constituents
2008
The aim of this study is evaluate either the antioxidant or pro-oxidant behaviour of some typical polyphenolic compounds of red wine, to investigate the influence of two different pH levels on the antioxidant properties and to clarify their activity–structure relationship. The antioxidant activity of compounds in hydrophilic solutions at pH 3.5 and pH 7.4 were measured by a competition kinetic test, based on the crocin bleaching. The position and the number of substitution groups influence the magnitude of the antioxidant activity of the polyphenolic compounds, but their antioxidant properties are also strongly influenced by the pH conditions. Increasing the pH, a considerable increase in a…
A research on the action of testosterone propionate and of ciproterone acetate on the mouse-killing behaviour of the adult rat.
1979
AbstractData demonstrate exactly that testosterone favour above all the killing behaviour of castrate males at birth in comparison with control males while ciproterone acetate turns out to be more effective in diminishing the killing behaviour of males having integral testicle and of androgenized females at birth in comparison with castrated males.The results point out that the killing behaviour of rats is affected by the presence of testosterone in the first days of life, and in the grown-up animal.
Short term diet of precooked corn meal almost lacking in tryptophan and interspecific rat-mouse aggressive behaviour.
1990
The content of tryptophan in a precooked corn meal and in 4 types of selected corn seeds: Zea mays indurata, identata, opaque/2 and Marano synth., has been determined by three different methods: ion-exchange chromatography, spectrofluorometry and spectrophotometry. This content is very low, less than 0.080% d.w. Alimentation for 4 d with a diet composed of precooked corn meal with a tryptophan content less than 0.025% induced the appearance of aggressive-cidal or aggressive non-cidal behaviour towards the mouse in more than half of Wistar rats bred in a room constantly lighted by a sodium steam light. The appearance of this behaviour is probably connected with a decrease in brain serotonin.
Food safety in hospital: knowledge, attitudes and practices of nursing staff of two hospitals in Sicily, Italy.
2007
Abstract Background Food hygiene in hospital poses peculiar problems, particularly given the presence of patients who could be more vulnerable than healthy subjects to microbiological and nutritional risks. Moreover, in nosocomial outbreaks of infectious intestinal disease, the mortality risk has been proved to be significantly higher than the community outbreaks and highest for foodborne outbreaks. On the other hand, the common involvement in the role of food handlers of nurses or domestic staff, not specifically trained about food hygiene and HACCP, may represent a further cause of concern. The purpose of this study was to evaluate knowledge, attitudes, and practices concerning food safet…
Maize based diets and possible neurobehavioural after-effects among some populations in the world
1996
Maize is a cereal particularly lacking in tryptophan, which is the precursor of serotonin, an important neurotransmitter. Altough complementary foods may eliminate tryptophan deficiency, serotonin deficiency may often continue to exist because of competition made by other Large Neutral Amino Acids (LNAA) against tryptophan for neuron access, since they use the same carrier to cross the blood-brain barrier. Thus serotonin synthesis depends on two variables: the amount of tryptophan and the trp/LNAA ratio (R). “R” is lowest for common maize, low for beans and, as a rule, for most vegetable foods, higher for meat. So, when maize is the preponderant food in the meal, the “R” value lowers and so…
The phenolic compounds of olive oil: structure, biological activity and beneficial effects on human health
2005
AbstractThe Mediterranean diet is rich in vegetables, cereals, fruit, fish, milk, wine and olive oil and has salutary biological functions. Epidemiological studies have shown a lower incidence of atherosclerosis, cardiovascular diseases and certain kinds of cancer in the Mediterranean area. Olive oil is the main source of fat, and the Mediterranean diet's healthy effects can in particular be attributed not only to the high relationship between unsaturated and saturated fatty acids in olive oil but also to the antioxidant property of its phenolic compounds. The main phenolic compounds, hydroxytyrosol and oleuropein, which give extra-virgin olive oil its bitter, pungent taste, have powerful a…
The Influence of Sex, of Castration in New-Born Males and of Androgen Treatment in New-Born Females on the Mouse-Killing Behaviour of the Rat
1979
AbstractThe results we have got on the mouse-killing behaviour of the rat point out the remarkable percentage difference between control males and control females, between integral males and males castrated at birth, and between normal females and females under the effects of androgens.Such results make us believe that the appearance of the killer behaviour is affected by the presence of testosterone in the first days of life of the rat.
Flavanones in Citrus fruit: structure-antioxidant activity relationships
2005
Epidemiological surveys have shown an inverse relationship between the intake of fruit and the incidence of coronary heart disease and some type of cancer. Data found in the literature regarding the flavonoids in general while this study focuses on flavanones, a subclass of flavonoids which occurs in Citrus fruit. The aim of this work is to elucidate the antioxidant or pro-oxidant behaviours of some common flavanones and to determine their activity–structure relationships as antioxidant using the crocin bleaching inhibition assay. The compounds studied were regarding both the aglycon form and the glycoside form. Data evidence that the substitution of the 7th OH group of the flavanones by a …
Environmental lighting and muricidal behaviour in the male Wistar rat.
1990
Effects of different conditions of environmental lighting on the appearance of the muricidal behaviour in male Wistar rats have been studied. The animals were kept under different conditions of environmental lighting: 1) natural day light alternated with the dark of the night; 2) sodium, continuous light emitted by a sodium steam lamp; 3) neon, continuous light emitted by fluorescent neon tubes. The continuous sodium steam light increased the percentage of animals becoming muricide when compared to animals bred in a natural environment with a normal succession of day-night lighting. On the contrary, this percentage decreased if the rats of the same group are exposed to continuous light emit…
Citrus flavonoids: Molecular structure, biological activity and nutritional properties: A review
2007
Abstract Epidemiological studies have shown an inverse relationship between dietary flavonoid intakes and cardiovascular diseases. Citrus fruits are the main winter fruits consumed in the Mediterranean diet, so they are the main source of dietary flavonoids. The possible beneficial effects are due, not only to the high amounts of vitamins and minerals, but also to the antioxidant properties of their flavonoids. Dietary flavonoids may help to supplement the body antioxidant defences against free radicals. These compounds’ possible beneficial effects are due to their antioxidant activity, which is related to the development of atherosclerosis and cancer, and to anti-inflammatory and antimicro…

A protocol to evaluate the antioxidant capacity by crocin bleaching assay in Pleurotus edible mushrooms
2008
Unpublished data on the chemical composition and nutritional value of Pleurotus mushrooms, growing on Umbelliferous plants (Apiaceae), are here reported. Cultivated basidiomata of four different Pleurotus taxa were analyzed in order to evaluate the composition in lipids, sugars, nitrogen, water, vitamins, ashes, and energetic values. The results showed that Pleurotus mushrooms are suitable in every type of diet thanks to their low caloric content, gastronomic value, vitamins, and mineral salt contents. The presence of a high content of vitamin B12 and riboflavin in Pleurotus nebrodensis is noteworthy.
