Both live and reactivated sea urchin sperm flagella were broken by passage through a pipette. Distal fragments stopped, but basal fragments continued to beat. Intact flagella were about 48 micrometer long; basal fragments were about 4-20 micrometer long. Beat periods of tritonated fragments were 11% shorter than those of unbroken controls, possibly reflecting decreased viscous loading; beat per...

Collagen XIV is known to bind to the dermatan sulfate chain of decorin and to the heparan sulfate chain of perlecan. To study its possible interaction with glycosaminoglycans, the NC1 domain of chicken collagen XIV was overproduced in E. coll. Purified NCI* (6-119)* appears poorly organized (the asterisks indicate the presence of extension sequences), but V8-protease generated fragments contain...

background and aims. it is believed that adherence of candida albicans to oral surfaces is a critical event in the colonization and development of oral diseases such as candida-associated denture stomatitis. although there is considerable information about the adherence of candida albicans to buccal epithelial cells and prosthetic materials, there is very little information available about the ...

in this study the bacterial growth inhibitory activity of peptide fragments produced from goat’s milk whey proteins by enzymatic hydrolysis using trypsin, ficin and a combination of both was investigated. goat’s milk whey proteins were isolated and subjected to enzymatic hydrolysis and peptides were purified by ultrafiltration followed by reverse-phase high-performance liquid chromatography (rp...

The velvet swimming crab Necora puber is a common species along the European Atlantic coasts. Due to its increasing commercial importance, many studies have been carried out to characterize its growth and reproduction, but no genetic assessment has ever been attempted at the population level. Here, we describe the genetic diversity and population structure of N. puber in northwestern Spain (Gal...

We propose an architecture and protocol for semantically rich information retrieval from a subject-speci c corpus of information objects. The technique assumes that information objects have been labeled using small directed graphs, called content labels. A content label subsumes the role of an abstract. Both content labels and queries are required to conform with a general framework (ontology) ...

Peptidoglycan (PG)-polysaccharide (PS) polymers derived from group A streptococcal cell walls were solubilized by M-1 mutanolysin (endo-N-acetylmuramidase) and phage-associated lysin (N-acetylmuramyl-l-alanine amidase). Fragments were isolated by ultrafiltration and a series of gel filtrations and were injected intravenously into Sprague-Dawley rats. No fragments with a molecular weight of less...

Abstract In order to obtain the fracture and fragmentation of a cased charge under blast loading, JWL equation state HMX-based PBX was fitted based on cylinder test firstly, then smooth particle hydrodynamics (SPH) method used perform simulation interior in meantime, an conducted. The results show that parameters were reasonably. simulated fragments velocities calculated from empirical formula ...

To interpret the provenance 0f Injana Formation, 20 sandstone samples of Formation were collected from Zawita and Dekala areas north Iraq (10 for each sections ), then thin section have been done sildes. The petrographic study showed that sedimentary, metamorphic igneous rock fragments, quartz (mono&polycrystalline) feldspars (microcline, orthoclase plagioclase) make up main grain component...
