We assessed folate nutritional status from birth to 12 months in fifty-one infants who were fed human milk (HM; n 20), casein-based formula (CBF; n 12) or soya-based formula (SBF; n 19). Folate contents in ninety-five HM samples obtained from twenty mothers for the first 6-month period and twelve CBF and nineteen SBF samples were measured by bioassay after trienzyme extraction. Folate intake was estimated by weighing infants before and after feeding in the HM group and by collecting formula intake records in the formula-fed groups. After solid foods were introduced, all foods consumed were included to estimate folate intake. Serum folate and total homocysteine (tHcy) concentrations were determined at 5 and 12 months of age, and infant growth was monitored for the first 12 months. Mean HM folate contents ranged from 201 to 365 nmol/l with an overall mean of 291 nmol/l, and the contents peaked at 2 months postpartum. HM folate contents were higher than those reported in North America. Folate contents in CBF and SBF were markedly higher than those in HM and those claimed on the product labels. The overall folate intakes in formula-fed infants were significantly higher than those in HM-fed infants, and this was associated with significantly higher folate and lower tHcy in formula-fed infants than HM-fed infants at 5 months. At 12 months, serum folate was significantly higher in the SBF group than the other groups, whereas serum tHcy and overall growth were similar among all groups.

Inflammatory markers in a randomised soya intervention among men.   Br J Nutr, 101(12): 1740-4.

The present analysis investigated the effect of soya foods on serum levels of six inflammatory markers, leptin, adiponectin, monocyte attractant protein 1 (MCP-1), macrophage inflammatory protein-1b (MIP-1b), IL-6 and C-reactive protein (CRP), and their relationship with BMI and lifetime soya intake. We randomised twenty-four men to a high- (two daily servings with 30-35 mg isoflavones per serving) or a low-soya diet for 3 months. After a 1-month washout period, the men crossed over to the ...

Flavonoids inhibit the genotoxicity of hydrogen peroxide (H2O2) and of the food mutagen 2-amino-3-methylimadazo[4,5-f]-quinoline (IQ) in lymphocytes from patients with inflammatory bowel disease (IBD).   Mutagenesis.

Inflammatory bowel disease (IBD) including Crohn's disease (CD) and ulcerative colitis (UC) is a chronic inflammatory gastrointestinal autoimmune condition with an inappropriate immune response. We investigated DNA damage induced in vitro in lymphocytes from IBD patients caused by oxidative stress through H(2)O(2) and 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) and whether the plant flavonoids, quercetin and epicatechin, found in fruits, tea and soybeans could effectively reduce such stress. ...

Effects of the level of sugarcane molasses on growth and carcass performance of Caribbean growing pigs reared under a ground sugarcane stalks feeding system.   Trop Anim Health Prod.

The influence of the level of sugarcane (SC) molasses on growth performance, carcass traits, and meat quality in Creole (CR) growing pigs fed with ground sugarcane stalks (GCS)-based diet was studied in a mixed farming system context. The aim of the study was to optimize the growth performance of CR pigs with SC-molasses as an energy source in this unconventional feeding. A total of 32 CR pigs were used from 30 to 60 kg of body weight (BW). The experimental dietary treatments consisted of four ... [Abstract] [Full-text]

Adsorption studies on the removal of coloring agent phenol red from wastewater using waste materials as adsorbents.   J Colloid Interface Sci.

Bottom ash, a waste of thermal power plants, and deoiled soya, an agricultural waste material, were employed for successful removal and recovery of hazardous phenol red dye from wastewaters. The adsorption characteristics and operational parameters were determined by monitoring different parameters such as effect of pH, effect of concentration of the dye, amount of adsorbents, contact time, and temperature. The equilibrium data were analyzed on the basis of various adsorption isotherm models, ... [Abstract] [Full-text]

Isoflavonoid content of Hong Kong soy foods.   J Agric Food Chem, 57(12): 5386-90.

Progress in understanding the effects of dietary soy isoflavones on chronic disease prevention in the Hong Kong Chinese population has been hampered by the lack of a comprehensive soy isoflavone database. In this study, we determined the concentrations and distribution of isoflavones in 47 foods included in a soy food frequency questionnaire by reverse-phase HPLC. Results indicated that most soy products contained isoflavones ranging from 1 mg of aglucon equivalents/100 g of wet weight (bean ... [Abstract] [Full-text]

Evaluation of body development, fat mass and lipid profile in rats fed with high-PUFA and -MUFA diets, after neonatal malnutrition.   Br J Nutr, 101(11): 1639-44.

Neonatal malnutrition is associated with several features of the metabolic syndrome, later in life. Although the recovery of malnutrition was studied with different high-fat diets, few studies compare the effects of enriched vegetable oil diets, containing PUFA and MUFA, after weaning. Our aim was to evaluate the recovery with soya oil- or rapeseed oil-enriched diet, after malnutrition in rats whose mothers were food restricted (FR) during lactation. Dams were 50 % FR and compared to standard ... [Abstract] [Full-text]

Proteomic Analysis of Mature Soybean Seeds from the Chernobyl Area Suggests Plant Adaptation to the Contaminated Environment.   J Proteome Res, 8(6): 2915-2922.

The explosion in one of the four reactors of the Chernobyl Nuclear Power Plant (CNPP, Chernobyl) caused the worst nuclear environmental disaster ever seen. Currently, 23 years after the accident, the soil in the close vicinity of CNPP is still significantly contaminated with long-living radioisotopes, such as (137)Cs. Despite this contamination, the plants growing in Chernobyl area were able to adapt to the radioactivity, and survive. The aim of this study was to investigate plant adaptation ...

Exposure to farm crops, livestock, and farm tasks and risk of glioma: the Upper Midwest Health Study.   Am J Epidemiol, 169(12): 1479-91.

Some studies of brain cancer have found an excess risk for farmers. The National Institute for Occupational Safety and Health previously found no increased glioma risk for ever (vs. never) being exposed to pesticides on a farm among 798 cases and 1,175 population-based controls (adult (ages 18-80 years) nonmetropolitan residents of Iowa, Michigan, Minnesota, and Wisconsin). For this analysis (1995-1998), 288 cases and 474 controls (or their proxies) who had lived on farms at age 18 years or ... [Abstract] [Full-text]
