  • These CNVs may show association with certain clinical conditions and help in predicting risk and also diagnosis. All these approaches have their merits and demerits and in general are tedious, time consuming and need manpower with stringent handling. This naturally prompted the development of several automated methods for culturing cells in mass scale, use of membrane bioreactors, and image analysis for interpreting the cytogenetic observations made.

  • Some carotenoids are considered as nutrients, such as alpha-, beta-, and gamma-carotene, and alpha- and beta-cryptoxanthin, exhibiting vitamin A activity following their metabolisation into retinol by humans (Biehler & Bohn, 2010; Biehler et al., 2010). Carotenoids are pigments with several conjugated double bonds (polyene chain), which could be divided into oxygen containing carotenoids (oxocarotenoids or xanthophylls), and non-oxygen containing carotenoids (carotenes).

  • MBR (Membrane Brio-Reactor) can be broadly defined as systems integrating biological degradation of waste products with membrane filtration. Set up of MBR plant is mainly utilizing a bioreactor and membrane filtration as one unit process for wastewater treatment thereby replacing, and in some cases supplementing, the solids separation function of secondary clarification and effluent filtration, resulting the possibility to eliminate the secondary clarification and operate at higher MLSS concentration....
