Farmed fish are exposed to a continuous antigenic pressure by microbial and environmental agents, which may lead to a condition of chronic inflammation. In view of the notion that polyphenols, largely contained in fruits and vegetables, are endowed with antioxidant and anti-inflammatory activities, farmed sea bass (Dicentrarchus labrax L.) have been(More)
Human ageing is characterized by several abnormalities of both innate and adaptive immune responses, thus leading to an increased frequency of infectious, inflammatory, allergic and autoimmune diseases. In elderly patients, among allergic diseases, asthma is a very common pathological event which complicates the dysfunction of many systems. Among a variety(More)
The in vitro ability of polyphenols, extracted from red grape, to modulate peripheral blood mononuclear cell responses has been evaluated in 20 obese (Ob) people. With regard to cytokine release in response to phorbol myristate acetate (PMA), levels of interleukin-2 (IL-2), interferon-γ (IFN-γ), IL-4, IL-10, and IL-17 were higher in the Ob than in healthy(More)
Solid inclusion complex between hydroxypropyl-β-cyclodextrin (HP-β-CD) and minoxidil (MXD) was prepared by freeze-drying and characterized by yield, drug loading and dissolution rate. Moreover, the complex was formulated as alginate gel (GEL HP-β-CD)/MXD 3.5% w/w). The efficacy of the novel GEL HP-β-CD)/MXD 3.5% w/w and of MXD 3.5% w/w(More)
The reinforcement of the defense mechanism of fish, through the administration of immunostimulants, is considered as a promising alternative to vaccines. Natural immunostimulants such as polyphenols, flavanoids, pigments and essential oils can modulate the innate immune response. In lower vertebrates, melano-macrophage centres, i.e. clusters of(More)
BACKGROUND Our recent findings have demonstrated that electromagnetic radiations (EMR) (1.8 GHz radiofrequency) are able to in vitro induce morphometrical and morphological modifications of human leukocytes from normal donors. METHODS In view of the evidence that polyphenols exert many beneficial effects on plants, animals and humans, leukocytes from(More)
