In order to study the mechanical properties of steel fiber rubber recycled brick concrete, ten groups concrete specimens with strength 15MPa were tested , one group was purely remaining nine mixed different rations admixture. Three fiber, another three granules, last both and granules. These by pressure testing machine respectively, maximum is calculated its stress value. The results proved tha...

β beta-tricalcium phosphate (β-TCP) granules are suitable for repair of bone defects. They have an osteoconductive effect shortly after implantation. However, dry granules are difficult to handle in the surgical room because of low weight and lack of cohesion. Incorporation of granules in a hydrogel could be a satisfactory solution. We have investigated the use of hyaluronic acid (HyA) as an aq...

1 The nature of the surface charge on secretory granules from the submaxillary gland of the guinea-pig has been studied by electrophoresis of the isolated granules. The granules suspended in buffered sucrose solutions move to the anode.2 Divalent ions reduce the anodal movements of the granules. Calcium and magnesium neutralize the net surface charge of the granules. This result supports the hy...

Messenger ribonucleoprotein (mRNP) granules are dynamic, self-assembling structures that harbor nontranslating mRNAs bound by various proteins that regulate mRNA translation, localization, and turnover. Their importance in gene expression regulation is far reaching, ranging from precise spatial-temporal control of mRNAs that drive developmental programs in oocytes and embryos, to similarly exqu...

theoretical biologist, and to get her interested in our problems. Around the turn of the millennium, a sparkling collaboration ensued which involved several very talented individuals from her group. With this collaboration, we could formulate our questions in testable hypotheses because they can be simulated. We have gone that way ever since. We still work together, as can be seen from our rece...

Stress granules are cytoplasmic foci that directly respond to the protein synthesis status of the cell. Various environmental insults, such as oxidative stress or extreme heat, block protein synthesis; consequently, mRNA will stall in translation, and stress granules will immediately form and become enriched with mRNAs. P54 DEAD box RNA helicases are components of RNA granules such as P-bodies ...

photobleaching reveal that the half-life of stress-granule-associated RNA-binding proteins is very brief, on the order of seconds to minutes, despite the fact that time-lapse microscopy reveals that individual stress granules persist for hours. This rapid shuttling of protein and RNA within stress granules suggests that their mRNP contents are continually sorted via fleeting associations with t...

II ABBIT HETEROPHIL LEUKOCYTES contain three distinctive types of granules, which have recently been designated primary, secondary, and tertiary granules according to their chronological appearance during cell development.’ The primary and secondary granules were conventionally designated azurophil and specific granules, respectively. Primary granules are present exclusively in early heterophil...

Secretory granules containing a hybrid protein consisting of the regulated secretory protein tissue plasminogen activator and an enhanced form of green fluorescent protein were tracked at high spatial resolution in growth cones of differentiated PC12 cells. Tracking shows that granules, unlike synaptic vesicles, generally are mobile in growth cones. Quantitative analysis of trajectories generat...

In the preoptic, infundibular and posterior recesses of the lamprey, Lampetra japonica cerebrospinal fluid (CSF)-contacting neurons are distributed much more abundantly than in higher vertebrates. They are classified into three different types on the basis of their granules size or electron density: type 1 containing round dense granules of large size (180--230 nm in diameter), type 2 containin...
