Human enteric adenoviruses of species F contain two fibers in the same virion, a long fiber which binds to coxsackievirus and adenovirus receptor (CAR) and a short fiber of unknown function. We have determined the high-resolution crystal structure of the short fiber head of human adenovirus serotype 41 (Ad41). The short fiber head has the characteristic fold of other known fiber heads but has t...

Cotton (Gossypium hirsutum L.) boll positions on a fruiting branch vary in their contribution to yield and fiber quality. Fiber properties are dependent on deposition of cellulose in the fiber cell wall, but information about the enzymatic differences in sucrose metabolism between these fruiting positions is lacking. Therefore, two cotton cultivars with different sensitivities to low temperatur...

Sorption potential of waste short hemp fibers for Pb(2+), Cd(2+) and Zn(2+) ions from aqueous media was explored. In order to assess the influence of hemp fiber chemical composition on their heavy metals sorption potential, lignin and hemicelluloses were removed selectively by chemical modification. The degree of fiber swelling and water retention value were determined in order to evaluate the ...

Mitochondrial content of skeletal muscle varies among fiber types, and changes in complex ways during aging. We evaluated the regulatory origins of differences in mitochondrial content among muscles of varied fiber type in F344xBNF1 rats, and how these regulatory patterns are altered with aging. In adult (12 month) animals we found that units citrate synthase (CS)/g tissue, a marker for mitocho...

OBJECTIVE High levels of dietary fiber, especially soluble fiber, are recommended to lower serum cholesterol levels and improve glycemic control in patients with type 2 diabetes. It is not clear, however, how high levels of fiber affect mineral balance. RESEARCH DESIGN AND METHODS In a randomized crossover study, 13 patients with type 2 diabetes were fed a high-fiber (50 g total and 25 g solu...

in recent years dietary fibers have been considered due to its beneficial effects. since the amount of fiber in dietary diet is usually less than the recommended amount (30 gr/day), fortification of bread with fiber can play an important role to achieve its health benefits. this project was studied to investigate on the possibility of supplementation of flour with dietary fibers. two different ...

AIM The aim of this study was to determine the effect of short fiber volume fraction and fiber length on some mechanical properties of short fiber-reinforced composite (FRC). METHODS AND MATERIALS Test specimens (2 x 2 x 25 mm3) and (9.5 x 5.5 x 3 mm3) were made from short random FRC and prepared with different fiber volumes (0%-22%) and fiber lengths (1-6 mm). Control specimens did not conta...

Diet-induced obesity is often modeled by comparing mice fed high-fat diet (HFD), which is made from purified ingredients, vs. normal chow diet (NCD), which is a low-fat assemblage of relatively unrefined plant and animal products. The mechanism by which HFD promotes adiposity is complex but thought to involve low-grade inflammation and altered gut microbiota. The goal of this study was to inves...
