Pork longissimus muscle was oxidized at 4 °C by mixed 10 μM FeCl(3)/100 μM ascorbate with 1, 5, 10, 20, 30, 40, or 50 mM H(2)O(2) (pH 6.2). Oxidation with >1 mM H(2)O(2) for 40 min significantly (P < 0.05) enhanced hydration of muscle samples, whereas oxidation with 40 and 50 mM H(2)O(2) for 2 min or with 20 mM H(2)O(2) for 40 min caused pronounced declines in water-holding capacity and product yield. The changes coincided with marked increases in the protein carbonyl content, TBARS formation, and cross-linking of both myofibrillar and sarcoplasmic proteins. Dye-tracing tests showed that the enhanced hydration at >1 mM H(2)O(2) was due to facilitated water diffusion into muscle tissue. This result was strongly corroborated by microscopic images that illustrated enlargements of intercellular spacing, that is, gaps, in oxidized muscle tissue, which served as canals for water diffusion.

The importance of protein dynamics for their biological activity is now well recognized. Different experimental and computational techniques have been employed to study protein dynamics, hierarchy of ...
To evaluate the importance of the water holding capacity for the elastically stored energy of protein gels, a range of gels were created from proteins from different origin (plant: pea and soy protein...
The role of heat-denatured sarcoplasmic proteins in water-holding is not well understood. Here we propose a new hypothesis that in PSE-like conditions denatured sarcoplasmic proteins aggregate within ...
We report the changes in the hydration dynamics around a model protein hen egg white lysozyme (HEWL) in water-dimethyl sulfoxide (DMSO) binary mixture using THz time domain spectroscopy (TTDS) techniq...
Protein surface hydration is critical to its structural stability, flexibility, dynamics and function. Recent observations of surface solvation on picosecond time scales have evoked debate on the orig...
This study evaluates the effect of early oral hydration on bowel movement after CS, it includes 2 groups: study group participants receive 100 ml water after 1hr from the end of CS, while ...
This is a randomized controlled open-label trial. During the study, adolescents and young adults scheduled to receive at least one intra-muscular (IM) vaccine will receive either oral wat...
The aim of this study is to determine the influence of changes in water intake on changes in cognitive function among preadolescent children. Further, the proposed work will determine the ...
The purpose of this study is to determine the effect of maternal hydration with oral isotonic solution and water on amniotic fluid (AF) index in women with normohydramnios.
OBJECTIVES: I. Characterize inheritance patterns of mutations in patients with beta-oxidation disorders.
An increased liquidity or decreased consistency of FECES, such as running stool. Fecal consistency is related to the ratio of water-holding capacity of insoluble solids to total water, rather than the amount of water present. Diarrhea is not hyperdefecation or increased fecal weight.
A surfactant that renders a surface wettable by water or enhances the spreading of water over the surface; used in foods and cosmetics; important in contrast media; also with contact lenses, dentures, and some prostheses. Synonyms: humectants; hydrating agents.
An enzyme that catalyzes reversibly the hydration of unsaturated fatty acyl-CoA to yield beta-hydroxyacyl-CoA. It plays a role in the oxidation of fatty acids and in mitochondrial fatty acid synthesis, has broad specificity, and is most active with crotonyl-CoA. EC 18.104.22.168.
A colorless, odorless, highly water soluble vinyl monomer formed from the hydration of acrylonitrile. It is primarily used in research laboratories for electrophoresis, chromatography, and electron microscopy and in the sewage and wastewater treatment industries.
An abundant pulmonary surfactant-associated protein that binds to a variety of lung pathogens and enhances their opsinization and killing by phagocytic cells. Surfactant protein D contains a N-terminal collagen-like domain and a C-terminal lectin domain that are characteristic of members of the collectin family of proteins.
Arthritis Fibromyalgia Gout Lupus Rheumatic Rheumatology is the medical specialty concerned with the diagnosis and management of disease involving joints, tendons, muscles, ligaments and associated structures (Oxford Medical Diction...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
