Abstract:

Spiders and scorpions are efficient predators arachnid (PA) consuming preys larger than themselves. Few studies reported, molecularly, the digestion in PA. This work describes a biochemical, transcriptomic and proteomic analysis of the midgut and midgut glands (MMG) and digestive juice (DJ) from Nephilengys cruentata and Tityus serrulatus MMG. Cathepsin L, B, D and F, legumain, trypsin, astacin, carbohydrases and lipases were identified by these approaches. Peptide isomerase and ctenitoxins, which are venom proteins were identified, showing a correlation among digestive and venom enzymes. Summ

Abstract:

The design demands on water and sanitation engineers are rapidly changing. The global population is set to rise from 7 billion to 10 billion by 2083. Urbanisation in developing regions is increasing at such a rate that a predicted 56% of the global population will live in an urban setting by 2025. Compounding these problems, the global water and energy crises are impacting the Global North and South alike. High-rate anaerobic digestion offers a low-cost, low-energy treatment alternative to the energy intensive aerobic technologies used today. Widespread implementation however is hindered by th

Abstract:

The rocky intertidal zone, experiencing fully marine and fully terrestrial conditions, has become increasingly investigated as a model ecosystem for studying the future implications of climate change. The barnacle, Balanus glandula, a common rocky intertidal inhabitant, plays an important role as a key prey item for many organisms. Low tide can be particularly challenging for barnacles as they are marine organisms subjected to the abiotic conditions of a terrestrial environment. The most stressful of these are increased temperature and decreased oxygen availability. This study aimed to investi

This knowledge was applied to develop a suitable formulated diet to be fed in combination with Artemia or used as a supplement to reduce production costs. The major impediment to closure of the life cycle of spiny lobsters has been an inadequate dietary regime, stemming from a lack of information on their feeding biology and ingestive and digestive capabilities.

Building on recent scholarship in the history of art which has started to reappraise the meaning of grotesque and scatological motifs, this thesis examines how digestion was conceived of as a model of creation, and how this was translated visually. Renaissance creativity was increasingly modelled on a series of natural processes like digestion, following a trend in favour of Aristotelian psychology. However, it has been largely overlooked in comparison to the bleeding, the pneumatic, and especially the procreative natural models, which have been extensively studied. The central argument of thi

Abstract:

The aim of this work was to quantify the utilisation by rats and pigs of microbial amino acids synthesised in their gastrointestinal tracts. The method which was developed is based on the oral administration of isotopes in non-amino acid form (15NH4Cl or 14C-polyglucose) and the measurement of the incorporation of these isotopes into the amino acids of the body protein of the animal. Since animals cannot incorporate 15N or 14C into certain of the essential amino acids, labelling of such amino acids is only possible via microbial amino acid synthesis and absorption.

It is known that muscles that lack KATP channel activity generate much greater unstimulated [Ca2+]i and force than normal muscles during fatigue. The increase in unstimulated force in KATP channel deficient muscles is abolished by a partial inhibition of L-type Ca2+ channels, suggesting that it is due to a Ca2+ influx through L-type Ca2+ channels and a subsequent increased myoplasmic Ca2+. However, there is also evidence that the increase in resting force is abolished by NAC, a ROS scavenger.

Abstract:

La colonisation du tractus digestif (TD) par une bactérie requiert un ensemble de fonctions qu’il est important de connaître pour comprendre le fonctionnement de cet écosystème. Dans ce travail, nous avons étudié l’adaptation de Lactococcus lactis à l’environnement digestif. L. Lactis est un levain de l'industrie laitière et les développements récents ont démontré son potentiel comme vecteur pour délivrer des molécules à visée médicale. L’adaptation au TD a été étudiée sur des souris monoxéniques pour L lactis par une approche protéomique. L. Lactis s’établit à une population équivalente à cel

Abstract:

L’ostéoporose touche principalement les femmes après la ménopause, c’est une maladie caractérisée par une détérioration de la minéralisation et de la micro-architecture de l’os. L’objectif du travail de thèse présenté ici est d’identifier une fraction protéique laitière ayant un effet stimulant sur la formation osseuse. Une telle fraction, ajoutée dans un produit ou un complément alimentaire, pourrait contribuer à réduire la perte osseuse. La première étape du projet consiste à produire les fractions laitières. Des protéines laitières (caséine ou protéines sériques) ont été digérées par des en

Abstract:

In animals, the accepted model of carbohydrate digestion and absorption involves reduction of disaccharides into the simple sugars glucose, fructose and galactose. Previous studies have shown the presence of disaccharides maltose and trehalose in the blood of several crab species, the crayfish and the American lobster. In 2011, a gene for a distinct disaccharide sucrose transporter (SCRT) was first found in Drosophila melanogaster and characterized using a yeast expression system. The purpose of the current study was to identify and characterize a putative disaccharide transporter analog in cr

Thesis (PhD)--Stellenbosch University, 2005.<br>ENGLISH ABSTRACT: This study describes the use of a gastro-intestinal model to screen lactic acid bacteria isolated from the gastro-intestinal tract of post-weaned piglets (raised on six different diets) for probiotic properties. Intestinal bacteria were isolated from ,the stomach, duodenum, jejunum, caecum, ileum and colon. The highest cell numbers (6 x 107 cfulg) were isolated from the ileum. No significant differences in viable cell counts were recorded for piglets raised on the six diets. Isolates with the best overall probiotic proper

Abstract:

Bien que les activites motrices rythmiques du pylore soient tres differentes chez la crevette (palaemon) et chez les grands crustaces, des methodes electrophysiologiques ont permis de montrer que les deux reseaux de neurones responsables de ces activites sont tres semblables. Ces memes methodes conduisent a conclure que la plasticite phylogenetique ne repose pas sur un remaniement du reseau mais qu'elle intervient essentiellement a travers des modifications de l'efficacite d'afferences modulatrices controlant l'expression des proprietes des neurones de reseau
