However, the underlying transcriptomic mechanisms by which exerts bioactivities are not completely understood.

Intrauterine growth restriction and overweight, obesity, and stunting in adolescents of indigenous communities of Chiapas, Mexico.

Background/objectives: Intrauterine growth restriction (IUGR) and low-birth-weight (LBW) are determinant factors in the development of metabolic diseases in children and adolescents. To estimate the magnitude of the association between LBW and IUGR with stunting or obesity among adolescents of two indigenous regions of the southern State of Chiapas, Mexico.

Subjects/methods: We assessed a random sample of 303 adolescents selected from a birth cohort study (2003) conducted in three hospitals serving urban and rural communities of Tzotzil-Tzeltal and Selva regions of Chiapas, Mexico.

Hypocholesterolemic Properties and Prebiotic Effects of Mexican Ganoderma lucidum in C57BL/6 Mice.

Edible and medicinal mushrooms contain bioactive compounds with promising effects on several cardiovascular risk biomarkers. However, strains of Ganoderma lucidum of Mexican origin have not yet been studied. Standardized extracts of G.

Environmental changes during the last millennium based on multi-proxy palaeoecological records in a savanna-forest mosaic from the northernmost Brazilian Amazon region.

The environmental changes and the dynamics of the savanna-forest mosaic, over the last 1050 years, have been reconstructed by pollen, charcoal, radiocarbon dating mineralogical and geochemical analyses of sediment cores taken from three different Mauritia flexuosapalm swamps in the northernmost part of the Brazilian Amazon region (northern state of Roraima). Studies on the relationship between the modern pollen rain and the regional vegetation provide additional information for the interpretation of the fossil pollen records. The fossil pollen assemblages and geochemical results indicate relatively wet climatic conditions throughout the recorded period.

Dietary fat modifies lipid metabolism in the adipose tissue of metabolic syndrome patients.

Adipose tissue (AT) is a key organ in the regulation of total body lipid homeostasis, which is responsible for the storage and release of fatty acids according to metabolic needs. We aimed to investigate the effect of the quantity and quality of dietary fat on the lipogenesis and lipolysis processes in the AT of metabolic syndrome (MetS) patients. A randomized, controlled trial conducted within the LIPGENE study assigned MetS patients to one of four diets: (a) high-saturated fatty acid (HSFA) (b) high-monounsaturated fatty acid, and (c, d) two low-fat, high-complex carbohydrate diets supplemented with long chain (LC) n-3 (LFHCC n-3) polyunsaturated fatty acids (PUFA) or placebo (LFHCC), for 12 weeks each.

Olive oil phenolic compounds decrease the postprandial inflammatory response by reducing postprandial plasma lipopolysaccharide levels.

We investigated the molecular mechanisms by which phenolic compounds (phenols) in virgin olive oil reduce the postprandial inflammatory response with the aim of identifying the transcription factor involved and the downstream effects. Olive oil-based breakfasts prepared with virgin olive oil (VOO) with high (398 ppm), intermediate (149 ppm) and low (70 ppm) phenol content were administered to 49 metabolic syndrome patients following a randomized crossover design. The consumption of a high-phenol VOO-based breakfast limited the increase of lipopolysaccharide plasma levels, TLR4, and SOCS3 proteins (p<0.

Endoplasmic reticulum stress in adipose tissue determines postprandial lipoprotein metabolism in metabolic syndrome patients.

Scope: Our aim was to ascertain whether the quality and quantity of fat in the diet may influence the ER stress at the postprandial state in adipose tissue by analyzing the gene expression of chaperones, folding enzymes, and activators of the UPR.

Methods And Results: A randomized, controlled trial conducted within the LIPGENE study assigned 39 MetS patients to one of four diets: high-SFA (HSFA; 38% energy (E) from fat, 16% E as SFA), high MUFA (HMUFA; 38% E from fat, 20% E as MUFA), and two low-fat, high-complex carbohydrate (LFHCC; 28% E from fat) diets supplemented with 1.24 g/day of long-chain n-3 PUFA or placebo for 12 wk each.

Dietary fat differentially influences the lipids storage on the adipose tissue in metabolic syndrome patients.

Purpose: Adipose tissue is now recognized as a highly active metabolic and endocrine organ. Our aim was to investigate the effect of the dietary fat on the two main adipose tissue functions, endocrine and lipid store, by analyzing the adipose tissue gene expression from metabolic syndrome patients.

Methods: A randomized, controlled trial conducted within the LIPGENE study assigned 39 metabolic syndrome patients to 1 of 4 isoenergetic diets: (1) high-saturated fatty acid (HSFA), (2) high-monounsaturated fatty acid (HMUFA), (3) low-fat, high-complex carbohydrate diet supplemented with long-chain n-3 fatty acids (LFHCC n-3), and (4) low-fat, high-complex carbohydrate diet supplemented with placebo (LFHCC), for 12 weeks each.

Postprandial inflammatory response in adipose tissue of patients with metabolic syndrome after the intake of different dietary models.

Scope: Dysfunctional adipose tissue may be an important trigger of molecular inflammatory pathways that cause cardiovascular diseases. Our aim was to determine whether the specific quality and quantity of dietary fat produce differential postprandial inflammatory responses in adipose tissue from metabolic syndrome (MetS) patients.

Methods And Results: A randomized, controlled trial conducted within the LIPGENE study assigned MetS patients to 1 of 4 diets: (i) high-saturated fatty acid (HSFA), (ii) high-monounsaturated fatty acid (HMUFA), (iii) low-fat, high-complex carbohydrate diet supplemented with n-3 polyunsaturated fatty acids (PUFA) (LFHCC n-3), and (iv) low-fat, high-complex carbohydrate diet supplemented with placebo (LFHCC), for 12 wk each.
