Limited Basis

In regard to the question posed in the title of this review, the answer is mixed. IPN is possible today but only on a limited basis and at high cost with uncertain benefit. A 1.1% amino acid dialysis solution for IPAA therapy is available in several European countries but has not yet been approved for use in the United States. When it becomes more widely available, IP AA should become an important tool, along with other types of therapy, for use in the maintenance of good nutritional status in PDpatients.

Abstract An experiment was conducted to investigate the effect of rice bran (RB) and Ronozyme® WX on apparent and true ileal amino acid (AA) digestibility coefficients in broiler chicks using a regression approach. Two hundred and forty 21-day-old Abor Acre plus chicks were randomly allotted to six diets with varying levels of RB (100, 200 and 300 g/kg) without (0g/kg) or with Ronozyme® WX (25g/kg) supplementation in a 2x3 factorial arrangement using a randomized complete block design. Each treatment had 5 replicates with 8 birds each. The birds were fed for 5 days (d 22–26). On d 26, digesta was sampled from distal ileum. Data were analyzed using general linear model at α0.05. Lysine had the highest concentration among the essential amino acids (AAs) while the lowest concentration was observed for threonine. Rice bran at 10% for the essential amino acids with enzyme was significantly higher but compared with concentrations of RB at 10% and 20% without enzyme. There were no significant differences among the true ileal amino acid digestibility coefficients except lysine (10% RB) without enzyme (0.91) which was significantly higher than 20% RB with enzyme (0.84) but similar to other treatments. Rice bran with enzyme had a significant (P &lt; 0.05) interactive effect on the apparent ileal digestibility coefficients of arginine, histidine, isoleucine methionine and phenylalanine. When RB was supplemented with enzyme, a significant (P &lt; 0.05) interactive effect on true ileal digestibility coefficients of arginine and methionine was observed. Rice bran-enzyme interaction had no significant effect on the non-essential AAs. The slopes of the regression lines ranged from 0.77 (arginine) to 0.98 (phenylalanine). In conclusion, enzyme supplementation did not significantly influence the digestibility coefficients of AA in rice bran. However, the inclusion of 10% and 20% RB supplemented with Ronozyme® can help to improve the methionine content in rice bran.

The Middle Ages

This study proposes a conceptualization of the industrial revolution in England in terms of the interaction of demographic and economic processes linked by the nutritional status of the population. By the eighteenth century the English economy had reached an important conjuncture. It had a larger accumulation of capital, and a larger urban sector capable of expanding commerce and production, than ever before. In addition, the population was well nourished by preindustrial standards and was about to benefit from the propitious harvest conditions of the 1730s and to procreate at a rate unsurpassed within recent memory (Wrigley and Schofield 1981). Population growth accelerated and had a market-expanding effect in a Boserupian fashion, triggering the industrial revolution; the roots of this transformation, however, extended back into the Middle Ages (Jones 1981; Boserup 1981). Thus the factors that have been regarded as crucial in unleashing the industrial revolution, such as the rise in the rate of saving, are less important within the framework presented here than the acceleration in the growth of a well-nourished population in a relatively developed economy.

Demographic Responses

Tropical waterbodies contain several species of toxic cyanobacteria including Microcystis, which adversely affect the somatic growth, survival and fecundity of zooplankton. Scenedesmus, one of the most common green algae, is even found in Microcystis -dominated waterbodies. It is, therefore possible that in natural ponds, rotifers and cladocerans feed on mixed phytoplankton species containing algae and cyanobacteria. In this work, we quantified demographic responses of three rotifer species (Brachionus calyciflorus, B. rubens, and Plationus patulus), and three cladoceran species (Simocephalus mixtus, Daphnia cf. mendotae and Moina macrocopa) fed toxic Microcystis aeruginosa only or mixed with Scenedesmus acutus. The highest population growth for both rotifer and cladoceran species was observed when Scenedesmus was offered alone or at 75 % of the diet. Daphnia cf. mendotae and B. rubens were less affected by Microcystis while M. macrocopa and B. calyciflorus were more adversely influenced, which was also corroborated by life table demography. In competition bioassays, D. cf. mendotae was more efficient, alone or in competition, when fed with 50 or 25 % of Microcystis. This work explains the dynamics of the zooplanktonic community against gradual changes in phytoplankton due to the presence of cyanobacteria.
