BACKGROUND Previous studies have suggested an effect of high arsenic concentration on cognitive and neurobehavioral function in humans. OBJECTIVE Our goal was to identify demographic and nutritional factors that are associated with As exposure and the influence of this exposure on cognitive function in school-age children. METHODS We recruited 602(More)
OBJECTIVE To ascertain the possible involvement of functional interleukin 10 (IL10) and tumour necrosis alpha (TNFalpha) cytokine promoter polymorphisms on the susceptibility to discoid and systemic lupus erythematosus (DLE, SLE), and their associations with immunological features. METHODS Single nucleotide polymorphisms of the IL10 (-1082, -819, and(More)
The antimicrobial activity of essential oils (EOs) of cinnamon (Cinnamon zeylanicum), clove (Syzygium aromaticum), basil (Ocimum basillicum), rosemary (Rosmarinus officinalis), dill (Anethum graveolens), and ginger (Zingiber officinalis) was evaluated over a range of concentrations in two types of contact tests (solid and vapor diffusion). The EOs were(More)
UNLABELLED Systemic lupus erythematosus (SLE) is the prototypical systemic autoimmune disease in humans and is characterized by the presence of hyperactive immune cells and aberrant antibody responses to nuclear and cytoplasmic antigens, including characteristic anti-double-stranded DNA antibodies. We performed a cross-sectional study in order to determine(More)
In rural Mexico and in many developing countries micronutrient deficiencies, growth stunting, and morbidity from infectious diseases are highly prevalent in young children. We assessed the extent to which growth stunting could be reversed and the number of infectious disease episodes reduced by zinc and/or iron supplementation. In a double-blind, randomized(More)
Traditional fermented foods are the best source for the isolation of strains with specific traits to act as functional starters and to keep the biodiversity of the culture collections. Besides, these strains could be used in the formulation of foods claimed to promote health benefits, i.e. those containing probiotic microorganisms. For the rational(More)
The present work was planned to research epidemiological and immunological features of systemic lupus erythematosus (SLE) in a Caucasian population from the north of Spain (Asturias). There is only one specialized immunology laboratory in this region where samples from all patients with a plausible or a firm diagnosis of SLE are referred for immunological(More)
The aim of the study presented here was to gain knowledge about the vapor-phase antimicrobial activity of selected essential oils and their major putatively active constituents against a range of foodborne bacterial and fungal strains. In a first step, the vapor-phase antimicrobial activities of three commercially available essential oils (EOs)-cinnamon(More)
Probiotics play an important role in the maintenance of the gastrointestinal barrier. In addition to direct effects on mucosal integrity, the interaction with the intestinal mucosa may have an active immunoregulatory effect. In the present work, we exposed HT29 intestinal epithelial cells to two Bifidobacterium species to determine their effect on gene(More)
OBJECTIVES To characterise and quantify the CD4+ CD25+ T cell population in patients with systemic lupus erythematosus (SLE) and to detect the possible influence of treatments and clinical manifestations. METHODS Characterisation of CD25(low) and CD25(high) CD4+ T cells from healthy controls and from patients with SLE was carried out using flow cytometry,(More)
