| histopathological changes in rat pancreas after fasting and cassava feeding. | histopathological changes in rat pancreas were induced by cyclic periods of experimental malnutrition or by cassava (manioc) feeding for 11 weeks. decline of body weight was correlated with decrease in testicular fat pad weight as a measure of body fat stores. a marked decrease in pancreatic weight in the cassava-fed group was correlated with shrinkage of acinar structures and degenerative features in exocrine pancreas. in the malnutrition group vacuolisation and loss of tissue architecture were ... | 1992 | 1457749 |
| comparison of the effects of cassava (manihot esculenta crantz) organic cyanide and inorganic cyanide on muscle and bone development in a nigerian breed of dog. | effects of cassava (manihot esculenta crantz)-borne organic cyanide and inorganic cyanide in the form of sodium cyanide on bone and muscle development were investigated in eighteen dogs of nigerian breed. after 16 weeks of stabilization in the laboratory from the time of purchase when the dogs were fed on the same diet, they were randomly assigned to three experimental groups of six dogs each. the control group was fed on rice while the other two groups were fed on either cassava (gari) or rice ... | 1992 | 1445827 |
| chronic pancreatitis and diabetes. | chronic pancreatitis is defined by a persistent destruction of the pancreatic parenchyma replaced by fibrosis. the lesions generally start in the exocrine gland, islets being attacked later in the fibrosis. the two most frequent forms are: 1. chronic calcifying pancreatitis which is a pancreatic lithiasis responsible for more than 95% of chronic pancreatitis. in its most frequent form, calculi are built up of more than 98% calcium salts together with fibres of a degraded residue of lithostathine ... | 1992 | 1445167 |
| iodine deficiency, other trace elements, and goitrogenic factors in the etiopathogeny of iodine deficiency disorders (idd). | severe goiter, cretinism, and the other iodine deficiency disorders (idd) have their main cause in the lack of availability of iodine from the soil linked to a severe limitation of food exchanges. apart from the degrees of severity of the iodine deficiency, the frequencies and symptomatologies of cretinism and the other idd are influenced by other goitrogenic factors and trace elements. thiocyanate overload originating from consumption of poorly detoxified cassava is such that this goitrogenic f ... | 1992 | 1375059 |
| fumaric acid production from hydrolysates of starch-based substrates. | fumaric acid production by rhizopus arrhizus from commercial hydrolysates of corn starch (i.e. glucose molasses) was studied at different initial concentrations of glucose (s) and c:n ratios (r) by performing a 3(2) factorial experiment. by using the response surface methodology and statistical analysis, fumaric acid (yf) and mycelial biomass (yx) yields, as referred to the initial concentration of glucose and fumaric acid productivity (pf), were fitted to the only significant first-order effect ... | 1992 | 1368809 |
| quality control of food products purchased by the national school-feeding programme in pernambuco, northeast brazil, from 1985 to 1988. | the effectiveness of the quality control system (qcs) implemented by the fundação de assistência ao escolar (fae) for quality control of food products from different types and origins purchased by the national school-feeding programme (nsfp) in pernambuco, northeast brazil, was evaluated. physicochemical, microbiological, microscopical and organopetical analyses were performed in 4,860 food samples and the main causes of alterations were detected. perishability was the characteristic used for di ... | 1992 | 1342181 |
| voluntary intake of "tiquira", an alcoholic beverage prepared from fermented manioc, decreases immunoglobulin production and increases self-reactivity in mice. | we studied the effects of chronic voluntary ingestion of "tiquira" (50%)--an alcoholic beverage prepared from fermented manioc, widely consumed in maranhão,--on the natural immunological activity of young adult (2-3 months old) c57b1/6j mice (16-17 g) by evaluating the number of plaque-forming cells (pfcs) in the spleen and by titrating serum antibodies by elisa. voluntary ingestion of "tiquira" for 30 days decreased immunoglobulin secretion in serum (control: 1600 +/- 30 vs experimental: 193 +/ ... | 1992 | 1304941 |
| a monkey model for mucoid vasculopathy. | mucoid vasculopathy is a new vascular entity observed by the author in autopsy material in kerala, a southwest coastal state of tropical india. this non-atherosclerotic, non-inflammatory connective tissue disorder affects mainly arteries, veins, vasa-nervosum and fascial tissues. characteristically, there are large deposits of acid mucopolysaccharide (glycosaminoglycan) material in the intima and media of arteries, accompanied by hyperplastic changes in cellular elements of the vessel wall and d ... | 1992 | 1295931 |
| cloning, partial sequencing and expression of a cdna coding for branching enzyme in cassava. | branching enzyme is involved in the synthesis of amylopectin in plant reserve starch. a cdna coding for cassava (manihot esculenta crantz) branching enzyme was cloned from a lambda gt11 cdna library using a potato cdna probe. the cloned cdna was partially sequenced. the sequence data confirmed the identity of the clone when compared to that of potato, the homology being ca. 80% at the nucleotide level and 85% at the amino acid level. furthermore, the cloned cassava cdna was able to restore branc ... | 1992 | 1281436 |

| dietary treatment of malnutrition. balance-sheets of the main nutrients. part ii. | results of a balance study of nitrogen, fat, electrolytes and trace-elements (fe, cu, zn, mn) with 3 1/i to 9 years old malnourished children in the kwilu region (zaïre) are given. the main components of the diets were fish, lactose free milk, caseinate, partial hydrolasate of albumin, fermented corn and soya (soy-ogi), medium-chain triglycerides, rice and the local foods manioc, peanuts and caterpillars. the lactose free milk and the soy-ogi were well tolerated since we found only a small quant ... | 1977 | 881298 |
| 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 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 |
| [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 |

| 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 |
| 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 |
