    Micropropagation protocol for Salvadora oleoides
    (Northeast Forestry University, 2019) Kumar, R; Najar, R.A; Gupta, K.B; Saini, R.G.
    Salvadora oleoides Decne. is a pharmaceutically important plant. Owing to poor seed formation, viability and, germination, and to anthropogenic disturbances, this species is on the verge of extinction. A reproducible micropropagation protocol to increase the population through tissue culture has been standardized and the results are reported here. Callus tissues were initiated from young leaves and stem explants. Leaf calluses proliferated with 1.5 mg/L BAP and 0.9 mg/L 2, 4-D with additives and continuous slow proliferation up to 15 weeks on 0.5 mg/L BAP and additives with 200 mg/L activated charcoal. Direct shoot initiation took place from stem node explants after 12 days; 4–5 shoots per node were produced in 30 days. Shoot clumps elongated and grew further on MS media supplemented with 2 mg/L BAP, 0.2 mg/L NAA and additives, which generated 20–23 shoots. The elongated shoots induced tap roots with 4 mg/L NAA and 200 mg/L activated charcoal in 12 days. In vitro raised plants produced secondary roots when transferred to pots containing vermiculite maintained at 28–35 °C. The plantlets successfully acclimatised in pots containing soil in natural conditions. © 2018, Northeast Forestry University and Springer-Verlag GmbH Germany, part of Springer Nature.

    Inflammatory response of gliadin protein isolated from various wheat varieties on human intestinal cell line
    (Academic Press, 2018) Gupta, K.B.; Upadhyay, S.; Saini, R.G.; Mantha, Anil K.; Dhiman, Monisha
    Wheat protein contributes a significant part in human diet, apart from its well-known nutritional values, wheat gluten/gliadin proteins are also responsible for the many allergic/inflammatory diseases and chronic inflammation in the small intestine may cause diarrhea and malabsorption, in a specific population of individuals. In the present study, the antigenic characteristics of twelve wheat varieties of diverse origin namely C273, C281, C286, C306, C518, C591, Agra Local, 9D, 8A, Raj4229, HD3027, NP824 released during 1920?2012 were evaluated. Gliadin proteins from these varieties were tested on human colon cancer cell line HCT116 to assess their effect on inflammation, oxidative and nitrosative stress, pro-inflammatory cytokines. The results show that these wheat varieties induced high levels of ROS/RNS and MPO activity which was further supported by the increase in the mRNA levels of a cytokine such as IL-1? and IL-15. It can be concluded that gliadin from these wheat varieties is suggested to act as a potential antigen by enhancing the level of inflammation irrespective of their year of release and origin which if not controlled may lead to the initiation of celiac disease in genetically susceptible individuals or may be responsible for other wheat protein intolerance associated diseases. ? 2018 Elsevier Ltd
