    The diversity on fruit colouration in plants directly depends on the flavonoids that explain the development of different pigmentation patterns. Anthocyanins are the major class of flavonoid pigments that are synthesized through flavonoid biosynthetic pathway. In the present study, two genes: PgUFGT gene and R2R3-PgMYB gene, involved in anthocyanin biosynthesis were analysed in four tissues of wild pomegranate. The structural genes, UDP-glucose: flavonoid-3-O-glucosyl transferase (PgUFGT; GenBank accession number: MK058491) and its myeloblastosis transcription factor (R2R3-PgMYB; GenBank accession number: MK092063) were isolated and their expression pattern were studied. Molecular modelling indicated that the main secondary structures of PgUFGT and R2R3-PgMYB genes are α-helix and random coil. In addition, expression profiling of PgUFGTand R2R3-PgMYB by quantitative-real time PCR indicated a positive correlation between anthocyanin content and their expression in leaves, flowers, green and red fruits of wild pomegranate. Among all the tissues, the red fruit exhibited high transcripts levels of PgUFGT as well as R2R3-PgMYB transcription factor. An extensive homology with UFGTs from other plants was revealed on comparative and bioinformatic analyses. Present study reveals that PgUFGT plays a predominant role in anthocyanin content in wild pomegranate fruits. Further, it is strongly suggested that R2R3-PgMYB transcription factor regulates the anthocyanin biosynthesis in wild pomegranate via expression of PgUFGT gene. This is the first study which provides an insight on expression profile of PgUFGT and R2R3-PgMYB that are involved in colour development and fruit ripening in wild pomegranate.

    Strategizing quality implementation in intensive care unit: a statistically-sound, novel approach using Delphi technique.

    Background: Ascendancy of Intensive Care Medicine in the realm of healthcare has made Continuous Quality Improvement (CQI) in Intensive Care Units (ICUs) most imperative for hospital administrators worldwide. Perspicuous identification of all clinical and non-clinical drivers warranting contemplation is the most arduous step in achieving the same. This study avers the effectiveness of a statistically-sound, novel approach using Delphi technique in identifying various drivers to be prioritized for strategizing CQI in the postoperative ICU of a premier tertiary care hospital in Asia. Methods: Three rounds of Delphi survey were initially planned. Mean Rank Scores (MRS) was used to rank the opinions in this study. Results: Statistically validated consensus was reached among expert participants on five drivers that should galvanize hospital administration vis-à-vis strategizing quality implementation in the post-operative ICU. Foremost among these was adequate staff that is tantamount to desirable staff-patient ratio (MRS: 9.4), and regular medical audit for sustainable quality in healthcare delivery (MRS: 9.1). Experts further concurred that communication skills of ICU staff (MRS: 8.9), continuous medical education and training of these staff (MRS: 7.6) along with perspicuous ‘Standard Operating Procedures’ (MRS: 7.1) were other points to be considered. Conclusions: With regard to the process of planning, identification of correct drivers holds the crux in strategizing quality implementation in any setup. Implementing change management is equally imperative. This approach can be used to realize both of these.
