Synthesis of digestive enzymes, food processing, and nutrient absorption in decapod crustaceans: a comparison to the mammalian model of digestion.
TLDR
Decapods produce a broad range of digestive enzymes including chitinases, cellulases, and collagenases with unique properties, which are synthesized in the F-cells of the hepatopancreas and encoded in the genome as pre-pro-proteins. Expand
Functional cytology of the hepatopancreas of decapod crustaceans

TLDR
The hepatopancreas of the Decapoda is most similar to the digestive gland of the Euphausiacea, supporting close taxonomic relationship of these two taxa. Expand
Response of facilitative glucose transporter 1 to salinity stress and dietary carbohydrate nutrition in white shrimp Litopenaeus vannamei
TLDR
It is suggested that GLUT1 is a conserved protein in L. vannamei, and changes in expression due to environmental salinity and dietary carbohydrate level and source are suggested. Expand
Nutrient Absorption in Invertebrates
TLDR
The sections in this article are: Modes of Nutrient Absorption, Kinetic and Energetic Aspects of Nutrients Transport, Experimental Systems Employed for the Measurement ofNutrient Transport, and Conclusion. Expand
Das Schicksal der Nährstoffe bei dem FlußkrebsOrconectes limosus
Summary1.U-14C-labelled glucose, amino acid mixture, palmitate, starch or protein were fed to the crayfish by means of a stomach catheter, 5 min to several hours after feeding determinations wereExpand
Der Stoffbestand des FlußkrebsesOrconectes limosus
Summary1.The quantitatively most important body constituents of freshly caught, male crayfish were determined at about monthly intervals from April 1969 until March 1971 except during the moultingExpand
Gesamtbestand an organischen Substanzen der Spinne Tegenaria atrica im Vergleich zu Protophormia terrae novae (Diptera) und Orconectes limosus (Crustacea, Decapoda)
Summary1.Whole bodies of the spider, Tegenaria atrica the fly, Protophormia terrae novae, and the crayfish, Orconectes limosus have been analyzed for their main organic constituents. The data areExpand
Life-cycle and functional cytology of the hepatopancreatic cells of Astacus astacus (Crustacea, Decapoda)
SummaryThe hepatopancreas of the freshwater crayfish Astacus astacus was reinvestigated by means of light and electron microscopy using refined techniques of tissue preservation. The resultsExpand
Lysine transport across the mucosal border of the perfused midgut in the freshwater shrimp,Macrobrachium rosenbergii
TLDR
The results suggest that cationic amino acid influx in crustacean intestine appears similar to processes reported for these solutes from a large variety of cell types, the major difference found for the shrimp gut is the apparent adaptation of the high-affinity carrier process for very low lysine concentrations.

  • 2001
TLDR
Recent advances in the understandings of hepatopancreatic D-glucose transport are shown, as obtained after isolation of purified R, F, B, and E-cell suspensions from the whole organ by centrifugal elutriation, and by protein expression in hepatopANCreatic mRNA-injected Xenopus laevis oocytes.

TLDR
During the course of the year distinct changes can be noted regarding the total concentration and composition of carbohydrates; the accumulation was most intensiv during winter, depletion in early spring and molt did not cause a similar effect. Expand

The peritrophic membranes, which is several groups of animals are produced by midgut epithelia, have been investigated most thoroughly in insects. The following results concern Crustacea: In theExpand
Molecular sieving of hydrophilic molecules by the rectal intima of the desert locust (Schistocerca gregaria).
TLDR
The properties of cuticles from the rectum and the integument are compared and the role of the rectal intima in the excretory process in the desert locust is discussed. Expand

TLDR
The anatomy of the proventriculus, digestive gland, midgut and its diverticula, and the rectum is described, and evidence for secretory functions of the midGut and anterior and posterior Diverticula is discussed. Expand
Intestinal absorption of sucrose in man: interrelation of hydrolysis and monosaccharide product absorption.
TLDR
It was recently demonstrated that appreciable amounts of the hydrolysis products accumulate intraluminally during the process of sucrose absorption in man and that these monosaccharides appear to move back from their mucosal site of hy-drolysis to the lumen. Expand
