Cognitive and contextual factors modulating grammar learning at older ages.

Second language learning has been shown more difficult for older than younger adults, however, the research trying to identify the sources of difficulty and possible modulating factors is scarce. Extrinsic (learning condition and complexity) and intrinsic factors (executive control) have been related to L2-grammar learning in younger adults. In the present study, we aim to assess whether extrinsic and intrinsic factors are also modulating grammar learning in older adults.

Transfer effects from language processing to visual attention dynamics: The impact of orthographic transparency.

The consistency between letters and sounds varies across languages. These differences have been proposed to be associated with different reading mechanisms (lexical vs. phonological), processing grain sizes (coarse vs.

Vitamin D deficiency is common and is associated with overweight in Mexican children aged 1-11 years.

Objective: To assess vitamin D dietary sources, intake and 25-hydroxyvitamin D status and their association with individual and sociodemographic characteristics in Mexican children.

Design: Data obtained from 2695 children aged 1-11 years from the Mexican National Health and Nutrition Survey (2012) were analysed. Diet was assessed by a 141-item FFQ.

Dietary patterns in Mexican adults are associated with risk of being overweight or obese.

Our objective was to identify and describe the major dietary patterns in the Mexican adult population and their association with being overweight or obese. Dietary intake was evaluated by a FFQ that was completed by 15,890 Mexican adults who participated in the National Health and Nutrition Survey 2006. Dietary patterns were generated by cluster analysis based on the percent contribution to total energy intake from 30 food groups.

Energy and nutrient intake among Mexican school-aged children, Mexican National Health and Nutrition Survey 2006.

Objective: To estimate energy, nutrient intake and diet adequacy in school-aged children based on the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006).

Material And Methods: Food intake data from food frequency questionnaires was analyzed for 8 716 children aged 5 to 11 years. Energy and nutrients intake and adequacy were obtained.

T helper cell cytokine profiles in preterm labor.

Problem: To compare concentrations of T-helper cell cytokines in women with preterm labor (PTL) to normal pregnancies.

Method Of Study: Fourteen women with PTL and 13 women with normal pregnancies from 24 to 34 weeks were enrolled in this pilot study. Peripheral blood mononuclear cells (PBMCs) and cervical secretions were collected.
