Adaptations biochimiques intestinales chez la truite: Influence de l'aliment et de la salinite sur quelques proprietes membranaires

Liao, I; Liu, F.

In order to develop effective formulated for Penaeus monodon , sufficient information is needed on its nutritional requirements. Unfortunately, research on this area has been very limited. This paper outlines the results of such research. Since data on the nutritional requirements of P. japonicus are relatively well established, some of these data are also reviewed in this paper and are used as a basis for assessing the nutritional requirements of P. monodon . Protein, lipid, carbohydrate, mineral and vitamin requirements are evaluated from the parameters of growth survival and feed efficiency. Studies on the effects of enzymes and the development of microparticulate diet for larvae are also summarized.

Allelochemicals from Alexandrium minutum induce rapid inhibition of metabolism and modify the membranes from Chaetoceros muelleri

Leray, C.

The authors report the results of physiological and biochemical experiments which confirm the important role player by fish (Salmo gairdneri ) intestinal mucosa in their osmoregulatory process. The ability of the dietary lipids to modulate this function is described. It was demonstrated that the ionic apical permeability of the enterocytes are related to their membrane lipid composition. The importance of the essential fatty acids is emphasized. The time course changes of the apical permeability are of value in improving sea water adaptation, similar conclusions are reported for Nacl supplementation.

Allocation du carbone et métabolisme azoté chez l'haptophyte Tisochrysis lutea

Long, Marc; Tallec, Kevin; Soudant, Philippe; Le Grand, Fabienne; Donval, Anne; Lambert, Christophe; Sarthou, Geraldine; Jolley, Dianne F.; Hegaret, Helene.

Allelochemical interactions are likely to be a contributing factor explaining the success of large blooms of the harmful marine dinoflagellate Alexandrium, however, the physiological mechanisms of allelochemical interactions remain poorly described. Here we investigated the sub-lethal effects (on an hourly scale) of a filtrate containing allelochemicals from Alexandrium minutum on the physiology of the common diatom Chaetoceros muelleri. The filtrate induced deleterious effects to the diatom physiology within only 30 min of exposure. Esterase activity and photosynthesis were drastically inhibited, with up to 34% of the population being metabolically inactive and up to 30% reduction in photosystem II quantum yield when exposed to the filtrate. In addition,...

Alterations in the lipid and soluble sugar content of melanoxylon brauna seeds during natural and accelerated ageing

Garnier, Matthieu.

The aim of this thesis is to improve knowledge on mechanisms involved in the response to nitrogen limitation and in lipid accumulation in the microalgae haptophyte Tisochrysis lutea. The wild type strain and a lipid accumulating mutant strain were grown under different nitrogen limitation and starvation and analyzed by functional genomics. Four genes of high-affinity nitrate/nitrite transporter (Nrt2) were identified and characterized to reveal the mechanisms involved in mineral absorption in this species. Transcriptomes of both strains were sequenced and proteins affected by nitrogen starvation and differentially expressed between the two strains were identified. We so identified the functions regulated by nitrogen deficiency and potentially involved in...

The decay of seeds is irreversible and at best can only be delayed by applying techniques that reduce the velocity of the metabolic reactions involved. There is little information on the biochemistry of tropical forest tree seeds related to their storability. It was investigated the influence of the composition of lipids and soluble sugars of two storage compartments, the cotyledons and the embryonic axis, of Melanoxylon brauna Schot. (Leguminosae- Caesalpinioideae), a hardwood known as black brauna, seeds stored at 20 ºC for 0, 3, 6, 9 and 12 months (natural ageing) and for 0, 24, 48, 72 and 96 hours at 40 ºC (accelerated ageing). The levels of fatty acids and monosaccharides varied differentially in each of the embryo storage compartments. Changes in...

The influence of apolipoprotein E alleles and genotypes on plasma lipid levels was determined in 185 individuals of mixed ethnicity living in Ouro Preto, Brazil. DNA was obtained from blood samples and the genotypes were determined by an RFLP-PCR procedure. The *3 allele was the most frequent (72%), followed by *4 (20%) and *2 (8%); *4 frequency was higher and *2 frequency was lower in the dyslipidemic group than in the normal control group. The *2 carriers presented lower LDL and total cholesterol levels compared to the *3 and *4 carriers. All six expected genotypes were observed in the individuals genotyped: E2/2 (2.1%), E4/4 (2.7%), E2/4 (3.7%), E2/3 (8.0%), E3/3 (53.3%), E3/4 (29.9%); no difference in genotype frequencies was found between the normal...

Cardiovascular disease is the primary cause of death in Brazil. Recent studies have shown that low birth weight and preterm birth are linked to a higher prevalence of cardiovascular disease. The aim of the present study was to compare the levels of lipids and apolipoproteins and atherogenic indexes between term and near-term newborn infants. A sample of umbilical cord blood was obtained from 135 newborns (66 males) divided into two groups: 25 near-term neonates (35-36.6 weeks of gestational age) and 110 term neonates (37-42 weeks of gestational age). The total cholesterol concentrations were higher in the near-term neonates than in the term group (94.04 ± 8.02 vs 70.42 ± 1.63 mg/dl, P < 0.01), due to an increase in the LDL-cholesterol fraction in the...

Abstract: The objective of this work was to determine the effect of photoperiod on the cannibalism, growth, and body composition of giant trahira (Hoplias intermedius) juveniles. A completely randomized design was employed, with four photoperiods - 0L:24D, 6L:18D, 12L:12D, and 18L:6D, hours of light (L): dark (D) - and four replicates, for a period of 90 days. The analyzed parameters were: cannibalism, growth in weight and length, food consumption, feed conversion, protein efficiency rate, muscle growth, and body composition (moisture, lipid, ash, and crude protein). Fish from the 12L:12D photoperiod showed the highest survival rate and no cannibalism, as well as a great uniformity for length and mass values at the end of the experiment. The best...

Changes in hormonal balance as key to reserve degradation after dormancy overcoming in Annona macroprophyllata and Annona purpurea seeds

Rev. Bras. Frutic.

Ferreira,Gisela; De-la-Cruz-Chacón,Ivan; González-Esquinca,Alma Rosa.

Abstract Studies on the effect of the applying of phytoregulators to overcome seed dormancy have been carried out in Annonaceae species, thus the endogenous relationship between abscisic acid and gibberellins after the application of phytoregulators needs to be known in these species. Considering the importance of hormonal balance in dormancy mechanisms, the aim of this research was to elucidate how endogenous ABA and GA concentrations change after the application of phytoregulators in seeds and how these changes affect reserve degradation during germination of Annona macroprophyllata and A. purpurea seeds. Seeds were submitted to three conditions: - no soaking, soaking-in-water and soaking-in-GA4+7+benzyladenine. ABA, GA, lipids, proteins, and total...

Levels of methylmalonic acid (MMA) comparable to those of human methylmalonic acidemia were achieved in blood (2-2.5 mmol/l) and brain (1.35 µmol/g) of rats by administering buffered MMA, pH 7.4, subcutaneously twice a day from the 5th to the 28th day of life. MMA doses ranged from 0.76 to 1.67 µmol/g as a function of animal age. Control rats were treated with saline in the same volumes. The animals were sacrificed by decapitation on the 28th day of age. Blood was taken and the brain was rapidly removed. Medulla, pons, the olfactory lobes and cerebellum were discarded and the rest of the brain ("cerebrum") was isolated. Body and "cerebrum" weight were measured, as well as the cholesterol and triglyceride concentrations in blood and the content of myelin,...

Comment protéger les acides gras polyinsaturés à longues chaînes oméga 3 (AGPI -- LC ω3) vis-à-vis de l’oxydation ?

Olofsson, Martin; Lamela, Teresa; Nilsson, Emmelie; Berge, Jean-pascal; Del Pino, Victoria; Uronen, Pauliina; Legrand, Catherine.

Instead of sole nutrient starvation to boost algal lipid production, we addressed nutrient limitation at two different seasons (autumn and spring) during outdoor cultivation in flat panel photobioreactors. Lipid accumulation, biomass and lipid productivity and changes in fatty acid composition of Nannochloropsis oculata were investigated under nitrogen (N) limitation (nitrate:phosphate N:P 5, N:P 2.5 molar ratio). N. oculata was able to maintain a high biomass productivity under N-limitation compared to N-sufficiency (N:P 20) at both seasons, which in spring resulted in nearly double lipid productivity under N-limited conditions (0.21 g L−1 day−1) compared to N-sufficiency (0.11 g L−1 day−1). Saturated and monounsaturated fatty acids increased from 76% to...

Comparative anatomy of calyx and foliar glands of Banisteriopsis C. B. Rob. (Malpighiaceae)

Genot, Claude; Eymard, Sylvie; Viau, Michèle.

Increase the consumption of long-chain omega 3 polyunsaturated fatty acids (LC ω3 PUFA) is highly recommended for their health benefits. However, these fatty acids are very prone to oxidation, which can impair sensory, nutritional and functional properties of foods. In this paper the various ways that increase LC ω3 PUFA stability during processing and storage of food products are reviewed. To efficiently protect LC ω3 PUFA during processing and storage of foods, a combined strategy, taking into account both the matrix and the process should be undertaken. First the quality of the raw materials should be rigorously controlled by, for example, increasing contents of in situ antioxidants and decreasing length of storage. Then, during processing and storage...
