Pomegranate juice is popular due to its unique health benefits, sensory characteristics and also a good source of bioactive compounds. Comparative study on processing effect of Not from Concentrate (NFC) and Reconstituted from concentrate (RFC) pomegranate juice on the nutritional and sensory characteristics of ‘Ganesh’ variant was conducted. Results showed that not much differences observed in parameters like pH, acidity, essential elements, protein, total sugars and polyphenol content between NFC and RFC. As per the study NFC had a better antioxidant activity with intracellular ROS inhibition of 11% higher with significant ( p < 0.05) than RFC in HepG2 cell lines. Total anthocyanin content was significantly different ( p < 0.05) in NFC (428.05 mg/l) compared to 326.74 mg/l in RFC expressed as cyanidin-3-glucoside. Iron uptake was 40 units (µg/mg protein) higher in NFC than RFC ( p < 0.05) in HepG2 cells. Sensory flavor profile showed NFC having significant differences with respect to characteristic pomegranate freshness, fruitiness, sweetness and astringency mouthfeel. RFC had higher sweetish and cooked flavor with additional vegetable like notes of beet and carrot. Based on the data better antioxidant activity, iron bioavailability, anthocyanin content and sensory attributes were captured in pomegranate NFC juices over RFC juices.

Abstract Objectives: The objectives of our study were to identify the student’s perceptions related to their academic failure and compare these perceptions with their nationality. Methods: A, non-interventional, bi national, comparative study was conducted in medical colleges of Pakistan and Saudi Arabia, in year 2015-2018, by taking a purposive sample of 210 students. All those who gave consent and scored less than fifty percent in their professional examinations were included. Data was analyzed using SPSS version 23. Frequencies and percentages were calculated, and Man Whitney U was applied to calculate p value. Results: According to the respondents, common reasons of failure identified were information overload (n=114,50%), difficult examination (n=101, 48%), poor teaching skills of teachers (n=82, 39%), system of education (n=75,36%) and unfair examination (n=78,37%). Eleven items in nationality group were found significant. Conclusion: Regardless of few cultural and environmental differences in factors contributing towards failure in students of different countries, the risk factors are common to all students. Moreover, most students tend to blame external factors more than internal ones. Keywords: Risk, factors, Perceived, academic, failure, students, medical, Saudi Arabia, nationality, Pakistan, perceptions
