The effects of altering forage particle size and source of rapidly degradable carbohydrates on in situ degradation and ruminal variables were studied in four Iranian male sheep. The study was designed as a Latin square with a 2 × 2 factorial arrangement of treatments including two carbohydrate sources (pelleted beet pulp vs. maizeand barley-based concentrate) and two lucerne particle sizes (2.3...

We used a double-labeling technique to compare the metabolism of complex carbohydrates by skin fibroblasts from patients with rheumatic heart disease and from ageand sex-matched normal controls. Fibroblasts were subcultured through a similar number of passages prior to their growth in the presence of "Cor H-labeled glucosamine, a precursor of complex carbohydrates. At the preconfluent, confluen...

During the past few years, considerable attention has been given to the impact of nutrition on kidney disease. The question arises of whether the effect of a moderate dietary protein restriction could be reinforced by enrichment of the diet with fermentable carbohydrates. Feeding fermentable carbohydrates may stimulate the extrarenal route of nitrogen (N) excretion through the fecal route. Such...

BACKGROUND Jujube extract is commonly used as a food additive and flavoring. The sensory properties of the extract, especially sweetness, are a critical factor determining the product quality and therefore affecting consumer acceptability. Small molecular carbohydrates make major contribution to the sweetness of the jujube extract, and their types and contents in the extract have direct influen...

Nanostructured carbon materials, including carbon nanotubes, membranes, and particles, are an important nanomaterial for many applications in nanoelectronics, sorption and separation, sensors, catalysis, and energy conversion and storage (e.g., double layer capacitors, and hydrogen storage). Varied methods have been developed to synthesize nanostructured carbon materials, such as DC arc-dischar...

The response to drought stress is a complicated process involving stress sensing, intracellular signaltransduction, and the execution of a cellular response. Transcription factors play important roles in the signaling pathways including abiotic stress. In the present study a rice NF-YA transcription factor gene was partially characterized following dehydration. Disrupting the gene via a T...

Structural carbohydrates are those that are resistant to the horse’s digestive enzymes. These carbohydrates occur in the cell wall portion of the plant and they must be fermented by bacteria living in the horse’s gut before they can be utilized by the horse. As a group, these carbohydrates are called plant fiber and they consist primarily of cellulose and hemicellulose. The various types of non...

The consumption of nondigestible carbohydrates is perceived as beneficial by health professionals and the general public, but the translation of this information into dietary practice, public health recommendations, and regulatory policy has proved difficult. Nondigestible carbohydrates are a heterogeneous entity, and their definition is problematic. Without a means to characterize the dietary ...
