The sperm quality index (SQI) is a tool used to predict overall rooster semen quality, fertility, and hatchability. However, semen must be diluted before SQI analysis, and research has shown that the SQI is most predictive of fertility at lower semen dilutions. Therefore, the present study was undertaken to determine why the SQI is not as predictive of fertility at higher semen dilutions and wh...

interaction effect of three level of male age broodstock and three type of diluents (distilled water and diluents 1 and 2) for duration of motility and eyed egg rate in rainbow trout (oncorhynchus mykiss) have been studied. there was no significant difference in activation of sperm by control group (distilled water) in different male ages (p?0.05). diluents 1, in 3+ year male broodstock has sho...

background: leishmaniases are a group of diseases caused by leishmania parasites .  growing of drug unresponsiveness in leishmaniasis patients necessitates the development of new drugs and accor­dingly a suitable assay is needed for evaluation of any modalities.  the aim of this study was to compare four drug assays methods, agar dilution, broth dilution, cylinder plate and disk diffusion, for ...

Although the mechanism of microtubule dynamic instability is thought to involve the hydrolysis of tubulin-bound GTP, the mechanism of GTP hydrolysis and the basis of microtubule stability are controversial. Video microscopy of individual microtubules and dilution protocols were used to examine the size and lifetime of the stabilizing cap. Purified porcine brain tubulin (7-23 microM) was assembl...

When Haemophilus influenzae type b was grown under iron limitation in continuous culture, the dilution rate affected the outer membrane protein and lipopolysaccharide composition. Investigations of the effect of the reduced availability of iron or other environmental parameters on these surface components should be controlled for growth rate.

This paper provides guidelines and advice to researchers engineers in the field of laser cladding related direct energy deposition techniques help establish a standardized approach quality assessment productivity metrics. Factors considered are deposit geometry, porosity, cracking, dilution, build-up/coverage rate, powder catchment efficiency.

BACKGROUND In the cryopreservation of blood, removing cryoprotectants from the cryopreserved blood safely and effectively is always being focused on. In our previous work, a dilution-filtration system was proposed to achieve the efficient clearance of cryoprotectants from the cryopreserved blood. METHOD In this study, a theoretical method is presented to optimize the diluent flow rate in the ...

Previous analysis of fibrinogen binding to human aspirin-treated gel-filtered platelets yielded upwardly concave Scatchard plots. To ascertain whether this was due to the presence of independent heterogeneous receptor populations binding fibrinogen with different affinities, the dissociation of purified 125I-fibrinogen from ADP-treated gel-filtered platelets was evaluated as a function of recep...
