The aim of the present study was to investigate the effects of long-term intervention with oligofructose-enriched inulin on behavioral cognitive, and visuomotor coordination in rats. Three-month-old male and female rats were randomly distributed into two groups receiving either a diet with 10% oligofructose-enriched inulin (SYN1) or a standard diet tested at 12, 18 and 24 months of age. Rats supplemented with SYN1 showed age- and sex-related improvements in spatial learning abilities, depression, anxiety, and visuomotor speed more prominent at 12

Bupropion is an antidepressant drug also used as a smoking cessation aid, which inhibits norepinephrine and dopamine re-uptake. Given its pharmacological properties, it has been associated with reports on psychosis and acute delirious episodes. Case We report the case of a patient with schizoaffective disorder who developed two psychotic episodes respectively after a four and a two-day administration of sustained-release (SR) bupropion at a dose of 150 mg/day. To our knowledge, this is the first reported case of involuntary rechallenge

The aim of the present study was to investigate the protective effects of the dextrin NUTRIOSE® 6 (Dex) on colonic inflammation. Five percent of Dex or Glucose (Glu) diets were administered for 2 weeks to Wistar male rats prior to colitis induction with 1mg of TNBS (2,4,6-Trinitrobenzenesulfonic acid) or 20% ethanol (vehicle). An aversive light stimulus avoidance test (ALSAT) was performed to assess the cognitive performances of rats that are correlated to pain. Growth, food intake and biological parameters as

BACKGROUND/AIMS: Numerous studies have indicated the value of music therapy in the management of patients with Alzheimer's disease. A recent pilot study demonstrated the feasibility and usefulness of a new music therapy technique. The aim of this controlled, randomised study was to assess the effects of this new music therapy technique on anxiety and depression in patients with mild to moderate Alzheimer-type dementia. METHODS: This was a single-centre, comparative, controlled, randomised study, with blinded assessment of its results. The duration of follow-up was

New amphiphilic derivatives of sodium alginate were prepared by covalent attachment of dodecylamine onto the polysaccharide via amide linkages at different substitution ratios, using 2-chloro-1-methylpyridinium iodide (CMPI) as coupling reagent. The aim was to limit the progressive loss of associative behaviour which occurs in the case of previously described dodecyl ester alginate derivatives due to hydrolysis of ester bonds. A series of hydrogels was obtained which differed by the amount of attached dodecyl tails. The stability and viscoelastic properties were

Depression is a major public health problem affecting about 12% of the world population. Drugs exist but they have many side effects. In the last few years, natural substances (e.g. flavonoids) have been tested to cure such disorders. Cocoa polyphenolic extract is a complex compound prepared from non-roasted cocoa beans containing high levels of flavonoids. The antidepressant-like effect of cocoa polyphenolic extract was evaluated using the forced swimming test in rats. Cocoa polyphenolic extract significantly reduced the duration of immobility

Ageing is associated with changes in physiology and morphology; nutritional strategies to decrease morbidity and to prolong life are of high interest. The aim of the study was to investigate the effects of lifelong supplementation with an oligofructose-enriched inulin on morphological and biological markers and lifespan in male and female rats. Male and female rats, age 3 months, were randomised into two groups to receive either a diet with 10 % of an oligofructose-enriched inulin (Synergy 1) or a standard

Glycaemic responses to the dextrin NUTRIOSE 6 (Dex) and the MALTISORB maltitol (Mal) have been studied previously but their effects on vigilance and cognitive performances are still not known. The present study assesses dose-related glycaemic responses following Dex administration and the hypothesis that Dex and Mal could modulate the glycaemic response, improve vigilance under stress conditions and improve cognitive performances in rats. The glycaemic responses following Dex and corn syrup GLUCIDEX IT 21 (CoS) solutions at 0.3, 0.5 and 1.0

Numerous studies have indicated that increased vulnerability to oxidative stress may be the main factor involved in functional declines during normal and pathological ageing, and that antioxidant agents, such as polyphenols, may improve or prevent these deficits. We examined whether 1-year administration of a cocoa polyphenolic extract (Acticoa powder), orally delivered at the dose of 24 mg/kg per d between 15 and 27 months of age, affects the onset of age-related cognitive deficits, urinary free dopamine levels and lifespan in

The aging process depends on genetic stability, metabolic control, and resistance to stress; longevity in particular seems related to resistance to stress. Responses to stress anticipate adaptation to an unacceptable disparity between real or imagined personal experience and expectation, including adaptive stress, anxiety, and depression. However, if stress persists, it may lead to chronic diseases, ranging from inflammation and cancer to degenerative diseases. For some time, only remarkable stress was acknowledged to induce immune and vascular alterations, such as infection
