Fiber-optic biosensor uses light transmittable tapered fiber to send excitation laser light and receive emitted fluorescent light. The fluorescent light excited by an evanescent wave generated by the laser is quantitatively related to biomolecules immobilized on the fiber surface [1]. An automated fiber-optic biosensor based detection method for Listeria monocytogenes was developed in this rese...

Human activities have increased the availability of nutrients in terrestrial and aquatic ecosystems. In grasslands, this eutrophication causes loss of plant species diversity, but the mechanism of this loss has been difficult to determine. Using experimental grassland plant communities, we found that addition of light to the grassland understory prevented the loss of biodiversity caused by eutr...

Extraction and chromatographic separation of fat-soluble vitamins is a challenging task, due to the sensitivity of these compounds towards light, oxygen, heat and pH. In light of this, supercritical fluid extraction (SFE) and supercritical fluid chromatography (SFC) are attractive techniques as they function at considerably milder conditions than conventional solvent-based analytical techniques...

Biological systems are unique matter with very complex morphology and highly heterogeneous chemical composition dominated by light elements. Discriminating qualitatively at the sub-micrometer level the lateral distribution of constituent elements, and correlating it to the sub-cellular biological structure, continues to be a challenge. The low-energy X-ray fluorescence microspectroscopy, recent...

PPurpose: The purpose of this study is to investigate the effect of both work to family enrichment and family to work enrichment on family satisfaction and work satisfaction. The moderating role of positive and negative affectivity is also examined in this regard. Methodology: This Study is an empirical survey research with the statistical population of faculty members of Iran’s universities. ...

this study was carried out to evaluate the effect of probiotic (bacillus latrospores and bacillus licheniformis) on growth and survival of silver carp larvae (hypophthalmichthys molitrix). rotifers (brachionus plicatilis) were used as live prey vehicle for probiotic transport. they were cultured in sea water with 15 ppt salinity and nannochloropsis oculata microalgae was used as feed. five trea...

Transcriptional assays, such as yeast two-hybrid and TANGO, that convert transient protein-protein interactions (PPIs) into stable expression of transgenes are powerful tools for PPI discovery, screens, and analysis of cell populations. However, such assays often have high background and lose information about PPI dynamics. We have developed SPARK (Specific Protein Association tool giving trans...
