Enterococcus faecalis is an important agent of endocarditis and urinary tract infections, which occur frequently in hospitals. Antimicrobial therapy is complicated by the emergence of drug-resistant strains, which contribute significantly to mortality associated with E. faecalis infection. In this issue of the JCI, Nallapareddy and colleagues report that E. faecalis produces pili on its surface...

Oyster mushroom is consumed all over the world due to its taste, flavor, high nutritional value, and some medicinal properties. Many species of this genus are rich in proteins with essential amino acids, polysaccharides, essential amino acids, dietary fibers, important minerals, and some vitamins. Because of this nutritional composition and presence of bioactive molecules, oyster mushroom has b...

In this research, a method for producing gum tragacanth (GT) fibers is presented. Ribbon type GT of Astragalus Gummifer species were obtained from local production lands. The gum was treated with alkali to increase its process ability, and allowed to stand for a period of time to reach the proper viscosity and/or to "ripen". Samples with different ripening times were prepared and their viscosit...

CuO nanoflakes with dimension of 50–150 nm × 200 were successfully immobilized on the surface cellulose fibers by an ultrafast (5 min reaction time), scalable microwave assisted method. The high retention up to 70% has been phenomenal considering that immobilization was carried out in absence any linker, binder or aid. Retention almost 87% nanostructures even after five consecutive recyclabilit...

Phoenix dactylifera L. (Ajwa date) is a natural plant that belongs to the Arecaceae family and consumed as fruit. It cultured all over world especially in desert areas like Arab regions has nutritional significance pharmacological values. P. dominates itself from other dates because of its enrichment dietary fibers, vitamins, minerals sugars. The study exhibits contains certain phytochemicals i...

The aim was to develop films with a new mixture of collagen fiber plus polyvinyl alcohol added oregano or rosemary essential oils at different levels (0%, 2%, 4% and 6%), as well assess the antimicrobial activity, physical, optical, microstructure molecular properties in films. An interaction between ingredients observed level by FTIR. amide II III bands, which are important verify conformation...

This paper investigated the effects of combining fibers with self-consolidating concrete (SCC). 12 series of test specimens were prepared using three kinds of fibers including steel, polyphenylene sulfide (PPS) and glass fibers with four different volumes fractions and one specimen without fibers as a reference sample. All plans were subjected to fresh concrete tests. For mechanical behavior of...
