Food dextrin protects against colonic inflamamtion and prevents cognitive impairments
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
Effect of music therapy on anxiety and depression in patients with Alzheimer’s type dementia: randomised, controlled study
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
Synthesis and rheological properties of hydrogels based on amphiphilic alginate-amide derivatives
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
