Effects of Dietary Cereal and Protein Source on Fiber Digestibility, Composition, and Metabolic Activity of the Intestinal Microbiota in Weaner Piglets

Autor: Carola Ellner, Anna G. Wessels, Jürgen Zentek

Publikováno v: Animals, Vol 12, Iss 1, p 109 (2022)

This study aimed to investigate the effect of fiber-rich rye and rapeseed meal (RSM) compared to wheat and soybean meal (SBM) on fiber digestibility and the composition and metabolic activity of intestinal microbiota. At weaning, 88 piglets were allo

Publikováno v: Check List, Vol 14, Iss 1, Pp 261-265 (2018)

Since 2011, the Bumpy Glassfrog, Centrolene heloderma (Duellman, 1981) was known only from a single location in the Mindo region of Ecuador. We report a newly discovered population located in the area of La Sierra, along Río Alambi, a stream system

Dietary fiber and its role in performance, welfare, and health of pigs

Autor: Ł. Grześkowiak, E.-M. Saliu, B. Martínez-Vallespín, J. R. Aschenbach, G. A. Brockmann, M. Fulde, S. Hartmann, B. Kuhla, R. Lucius, C. C. Metges, H. J. Rothkötter, W. Vahjen, A. G. Wessels, J. Zentek

Dietary fiber (DF) is receiving increasing attention, and its importance in pig nutrition is now acknowledged. Although DF for pigs was frowned upon for a long time because of reductions in energy intake and digestibility of other nutrients, it has b

Effects of a pre- and probiotic mixture and an autogenous vaccine on growth performance in newly weaned piglets experimentally challenged with an enterotoxigenic Escherichia coli strain

Autor: Katharina Zeilinger, Anna G Wessels, Wilfried Vahjen, Jürgen Zentek

Beneficial effects of pro- and prebiotics in weanling piglets are of great interest in livestock production. Similarly, the use of specific vaccines is of interest as alternative to antibiotics to reduce postweaning performance losses. The aim of thi

Impact of dietary supplementation of l-Arginine, l-Glutamine, and the combination of both on nursing performance of multiparous sows

Autor: Anna G Wessels, Aude Simongiovanni, Jürgen Zentek

Publikováno v: Translational Animal Science. 7

Dietary supplementation with arginine (Arg) or glutamine (Gln) has been considered as an option to improve nursing performance in reproductive sows. This study investigated whether a low-level supplementation of Arg or Gln or a blend of both could mo

Computational Reverse-Engineering Analysis of Scattering Experiments (CREASE) on Amphiphilic Block Polymer Solutions: Cylindrical and Fibrillar Assembly

Autor: Michiel G. Wessels, Arthi Jayaraman

Publikováno v: Macromolecules. 54:783-796

In this paper, we extend a recently developed computational reverse-engineering analysis for scattering experiments (CREASE) approach to analyze cylindrical, fibrillar, and elliptical cylindrical structures assembled in amphiphilic block copolymer so

High Leucine Diets Stimulate Cerebral Branched-Chain Amino Acid Degradation and Modify Serotonin and Ketone Body Concentrations in a Pig Model.

Autor: Anna G Wessels, Holger Kluge, Frank Hirche, Andreas Kiowski, Alexandra Schutkowski, Etienne Corrent, Jörg Bartelt, Bettina König, Gabriele I Stangl

Publikováno v: PLoS ONE, Vol 11, Iss 3, p e0150376 (2016)

In addition to its role as an essential protein component, leucine (Leu) displays several other metabolic functions such as activation of protein synthesis. This property makes it an interesting amino acid for the therapy of human muscle atrophy and

Hierarchical Self-Assembly of Poly(d-glucose carbonate) Amphiphilic Block Copolymers in Mixed Solvents

Autor: Jee Young Lee, Yue Song, Michiel G. Wessels, Arthi Jayaraman, Darrin J. Pochan, Karen L. Wooley

Publikováno v: Macromolecules. 53:8581-8591

We report the fibril formation of poly(d-glucose carbonate) (PGC)-based amphiphilic diblock copolymers using solution assembly. Unlike conventional cylindrical micelles constructed from amphiphilic...

Self-assembly of amphiphilic polymers of varying architectures near attractive surfaces

Autor: Arthi Jayaraman, Michiel G. Wessels

Publikováno v: Soft Matter. 16:623-633

We use coarse-grained molecular dynamics simulations to investigate the assembly of A-B amphiphilic polymers near/on surfaces as a function of polymer architecture and surface attraction to the solvophobic B-block in the polymer. We study four polyme
