| serum levels of organochlorine pesticides in blood donors: a biomonitoring survey in the north of brazil, 2010-2011. | data on exposure to organochlorine (oc) pesticides in the brazilian population are lacking. the purpose of this study was to investigate the distribution of serum levels of oc pesticides in brazilian blood donors and to determine factors potentially influencing exposure levels. to conduct this biomonitoring survey, blood samples were collected from blood donors attending the hematherapic unit in rio branco, north of brazil, in 2010-2011. a total of 1183 (99%) subjects answered to a questionnaire ... | 0 | 28456124 |
| the chemistry of diet: medicine, nutrition, and staple foods in imperial brazil. | brazilian cuisine is much admired by present-day international chefs. however, in the nineteenth century, local ingredients and recipes were looked down upon by the portuguese colonists, as well as by visiting european naturalists. this fact, together with medical and chemical views formulated throughout the 1800s, led locally trained doctors to attribute the occurrence of countless diseases that devastated rio de janeiro to local staple foods, particularly corn and manioc flour. in the first pa ... | 0 | 26924333 |
| acrylamide levels in selected colombian foods. | acrylamide (aa) levels in conventional (n = 112) and traditional (n = 43) colombian foods were analysed by gas chromatography with mass spectrometry (gc/ms) detection. samples included: infant powdered formula, coffee and chocolate powders, corn snacks, bakery products and tuber-, meat- and vegetable-based foods. there was a wide variability in aa levels among different foods and within different brands of the same food, especially for coffee powder, breakfast cereals biscuits and french fries s ... | 0 | 25494681 |

| high-temperature production of protein-enriched feed from cassava by fungi. | a simple, nonaseptic, low-cast process for the conversion of cassava, a starchy tropical root crop, into microbial protein for use as animal feed was sought. screening tests culminated in the isolation of a thermotolerant, amylase-producing mold, designated i-21, which was identified as aspergillus fumigatus. the optimum ph for protein synthesis was 3-5, but the optimum temperature was less than the desired temperature (larger than or equal to 45 c) required for a nonaseptic fermentation. a. fum ... | 1975 | 2105 |
| food protein sources. | work on food, planned by the u.m. (use and management) section of the u.k. committe, was limited to sources of protein because we agreed that more problems calling for research were likely to arise in getting adequate supplies of protein than of other types of food. deer meat can be produced on land too rough and exposed for sheep; parts of the work on their metabolism and food requirements necessitated building a mobile laboratory. the manner in which the nutritive value of maize is affected by ... | 1976 | 8803 |
| studies on the phyllosphere microflora of tapioca (manihot utilissima pohl). | studies on the phyllosphere microflora of tapioca (manihot utilissima pohl.) revealed that incidence of bacteria, fungi, and actinomycetes is indipendent of the variety, but dependent on the age. the bacteria and fungi increased with increasing age of the leaf and were more on mature leaves, whereas no such difference was noticed in the occurrence of actinomycetes. the large majority of the isolates, that were gram-negative bacteria, was also amino acid-requiring. the chromogenic types occurred ... | 1976 | 189529 |
| exoenzymic activity of alpha-amylase immobilized on a phenol-formaldehyde resin. | amylose and amylopectin from two starch sources were partially degraded by alpha-amylase immobilized on a phenol-formaldehyde resin. the degradation products were fractioned by gel-permeation chromatography and high-pressure, liquid chromatography. two distinct fractions were obtained from tapioca amylose. one is a fragment having a molecular weight exceeding 200,000, and the other consists of oligosaccharides of low molecular weight with a degree of polymerization of 1-8. in contrast, treatment ... | 1976 | 820427 |
| effect of modified and unmodified tapioca starches on 59fe retention in rats. | the effects of a chemically-modified tapioca starch hydroxypropyl distarch phosphate (hdp), and unmodified tapioca starch (ums) on 59fe retention by rats were compared. three experimental variables were evaluated: 1) the type of starch in the diet, 2) cooking of either the starch alone or the entire diet, and 3) the iron status of the rats. there were no significant differences in 59re retention between iron-adequate rats fed either ums or hdp. 59fe retention by iron-deficient rats was not affec ... | 1976 | 993856 |
| the possibility of dietary protective factors in duodenal ulcer. ii. an investigation into the effect of pre-feeding with different diets and of instillation of foodstuffs into the stomach on the incidence of ulcers in pylorus-ligated rats. | rats pre-fed on a south indian diet show a much higher incidence of ulceration of the stomach after pyloric ligation than those on a north indian diet. removing vegetables and pulses from the north indian diet deprives it of its protective effect. staple foodstuffs with a high buffer content (unmilled rice, unrefined wheat and a millet [ragi]) placed in the stomach after pyloric ligation are also protective, but those with a low buffer content (milled rice, tapioca, sorghum and maize) are not pr ... | 1976 | 995789 |
| [nutritive value of macaçar bean (vigna unguiculatta l.) walp (author's transl)]. | the biological value of dry and immature macaçar bean (vigna unguiculatta l.) walp, isolated or associated to manioc flour, was studied. thirty-six male albino rats, wistar strain, aged 23 days, were divided into six groups and fed experimental and control (casein) diets for 28 days. the weight curve and the per of the animals fed dry and immature macaçar bean either isolated or associated to manioc flour were lower than those of the casein group. the data lead to the conclusion that the macaçar ... | 1976 | 1013409 |
| recurrent tapioca melanoma of the iris and ciliary body treated with the argon laser. | a 25-year-old white woman underwent iridocyclectomy for an iris tumor. clinically, histologically, and ultrastructurally this tumor was the same as a recently reported tapioca melanoma of the iris. during the next four months, there were recurrent growths on the ciliary body that we treated with the argon laser through a three-mirror lens. no further recurrences of the tumor were noted three years later. | 1976 | 986119 |

| [pathogenesis of endemic goiter: evidence of a dietary factor different from iodine deficiency (author's transl)]. | the role of cassava was investigated in particularly severe endemic goiter area (ubangi). dietary intake of cassava induces an increase of plasma thiocyanate concentration and an increase of urinary excretion of stable iodine. generalized iodine deficiency induces very high thyroid uptakes; the other parameters of thyroid function are more or less affected according to the dietary intake of thiocyanate. when thiocyanate intake is high an adaptation is obtained only at the expense of a drop of pl ... | 1978 | 686655 |
| effect of linamarin on thiocyanate production and thyroid activity in rats. | the principal cyanogenic glucoside in cassava is linamarin (2-hydroxyisobutyronitrile-beta-d-glucoside). addition of pure linamarin to a diet based on 10% vitamin-free casein did not affect the weight gain of rats. however, as expected, the animals that received the casein diet supplemented with methionine gained more weight than those that received the unsupplemented diet. the amount of thiocyanate ion excreted in the urine by the animals that received linamarin was higher than that excreted by ... | 1978 | 731726 |
| effects of cyanogenic agents on reproduction and neonatal development in rats. | a diet consisting of 50% gari (a form of cassava meal) was found to cause no significant biochemical and haematological changes in adult female rats. although this diet caused a significant increase in their serum thiocyanate levels, there was no corresponding significant increase in the weight of their thyroid glands. the offspring of these rats had significantly lower birth weights and brain weights and never attained the same adult weights as those of the controls. adult female rats fed a die ... | 1979 | 230860 |
| the origin of nitrogen incorporated into compounds in the rumen bacteria of steers given protein- and urea-containing diets. | 1. two young friesian steers fitted with rumen cannulas were each given three different isonitrogenous and isoenergetic diets for successive periods of 2-3 weeks. the diets consisted mainly of straw and tapioca, with the nitrogen supplied mainly as decorticated groundnut meal(dcgm; diet a), in approximately equal amounts of dcgm and urea (diet b), or entirely as urea (diet c). 2. at the end of each period on a given diet, part of the dietary urea of a morning feed was replaced by a solution of [ ... | 1979 | 420753 |
