| 1 | Antioxidant activity and identification of bioactive compounds from leaves of Anthocephalus cadamba by ultra-performance liquid chromatography/electrospray ionization quadrupole time of flight mass spectrometry显示文摘Objective:To evaluate the antioxidant potential of different extract/fractions of Anthocephalus cadamba(A.cadamba)(Roxb.) Miq.(Rubiaceae) and study the tentative identification of their active constituents.Methods:The extract/fractions were screened for antioxidant activity using various in vitro assays viz.DPPH assay,ABTS assay,superoxide anion radical scavenging assay, reducing power assay and plasmid DNA nicking assay.Total phenolic content of extract/fractions was determined by colorimetric method.An ultra-performance LC-electrospray-quadrupoletime of flight mass spectrometry method was used to analyse the active constituents of extract/ fractions of A.cadamba.Results:The ethyl acetate fraction was found to be most active fraction in all the assays as compared to other extract/fractions.The IC50 value of ethyl acetate fraction (ETAC fraction) was 21.24μg/mL,1.12μg/mL,9.68μg/mL and S7.81μg/mL in DPPH assay, ABTS assay,reducing power assay and superoxide scavenging assay respectively.All the extract/ fractions also showed the potential to protect the plasmid DNA(pBR322) against the attack of hydroxyl radicals generated by Fenton’s reagent.The bioactive compounds were identified by UPLC-ESI-QTOF-MS,by comparing the mass andλmax with literature values.Conclusions:The potential of the extract/fractions to scavenge different free radicals in different systems indicated that they may be useful therapeutic agents for treating radical-related pathologic damage. | Madhu Chandel Upendra Sharma Neeraj Kumar Bikram Singh Satwinderjeet Kaur | 2012 | Asian Pacific Journal of Tropical Medicine2012，5，12： | 6 |
| 2 | Soil Carbon and Nitrogen in Response to Perennial Bioenergy Grass, Cover Crop and Nitrogen Fertilization显示文摘Cover crop and nitrogen(N) fertilization may maintain soil organic matter under bioenergy perennial grass where removal of aboveground biomass for feedstock to produce cellulosic ethanol can reduce soil quality. We evaluated the effects of cover crops and N fertilization rates on soil organic carbon(C)(SOC), total N(STN), ammonium N(NH_4-N), and nitrate N(NO_3-N) contents at the0–5, 5–15, and 15–30 cm depths under perennial bioenergy grass from 2010 to 2014 in the southeastern USA. Treatments included unbalanced combinations of perennial bioenergy grass, energy cane(Saccharum spontaneum L.) or elephant grass(Pennisetum purpureum Schumach.), cover crop, crimson clover(Trifolium incarnatum L.), and N fertilization rates(0, 100, and 200 kg N ha^(-1)). Cover crop biomass and C and N contents were greater in the treatment of energy cane with cover crop and 100 kg N ha^(-1) than in the treatment of energy cane and elephant grass. The SOC and STN contents at 0–5 and 5–15 cm were 9%–20% greater in the treatments of elephant grass with cover crop and with or without 100 kg N ha^(-1)than in most of the other treatments. The soil NO_3-N content at 0–5 cm was 31%–45% greater in the treatment of energy cane with cover crop and 100 kg N ha^(-1)than in most of the other treatments.The SOC sequestration increased from 0.1 to 1.0 Mg C ha^(-1)year^(-1)and the STN sequestration from 0.03 to 0.11 Mg N ha^(-1)year^(-1)from 2010 to 2014 for various treatments and depths. In contrast, the soil NH_4-N and NO_3-N contents varied among treatments,depths, and years. Soil C and N storages can be enriched and residual NO_3-N content can be reduced by using elephant grass with cover crop and with or without N fertilization at a moderate rate. | Upendra M.

| 4 | Mitigating N2O and NO Emissions from Direct-Seeded Rice with Nitrification Inhibitor and Urea Deep Placement显示文摘Soil-emitted nitrous oxide(N2O) and nitric oxide(NO) in crop production are harmful nitrogen(N) emissions that may contribute both directly and indirectly to global warming. Application of nitrification inhibitors, such as dicyandiamide(DCD), and urea deep placement(UDP), are considered effective approaches to reduce these emissions. This study investigated the effects of DCD and UDP, compared to urea and potassium nitrate, on emissions, nitrogen use efficiency and grain yields under direct-seeded rice. High-frequency measurements of N2O and NO emissions were conducted using the automated closed chamber method throughout the crop-growing season and during the ratoon crop. Both UDP and DCD were effective in reducing N2O emissions by 95% and 73%, respectively. The highest emission factor(1.53% of applied N) was observed in urea, while the lowest was in UDP(0.08%). Emission peaks were mainly associated with fertilization events and appeared within one to two weeks of fertilization. Those emission peaks contributed to 65%–98% of the total seasonal emissions. Residual effects of fertilizer treatments on the N2O emissions from the ratoon crop were not significant;however, the urea treatment contributed 2%, whereas UDP contributed to 44% of the total annual emissions. On the other hand, cumulative NO emissions were not significant in either the rice or ratoon crops. UDP and DCD increased grain yields by 16%–19% and N recovery efficiency by 30%–40% over urea. The results suggested that the use of DCD and UDP could mitigate N2O emissions and increase grain yields and nitrogen use efficiency under direct-seeded rice condition. | Yam Kanta Gaihre Upendra Singh Wendie DBible Job Fugice Jr Joaquin Sanabria | 2020 | Rice science2020，27，5： | 1 |

| 8 | Egg-derived tyrosine phosphatase as a Potential Biomarker for Muscle Ageing and Degeneration in Drosophila melanogaster显示文摘Ageing is associated with declined activity of behaviors,physiology and metabolic processes(Arking,2006).Investigations in model organisms have indicated the existence of'functional senescence',the progressive decline of biological functions with age and the decline in the activity may vary from tissue to tissue.Consequently,studies pertaining to the key organs/tissues whose functions deteriorate/fail with age have led to the development of tissue specific ageing biomarkers(Grotewiel et al.,2005;Demontis et al.,2013). | Salam Herojeet Singh Nallur B.Ramachandra Upendra Nongthomba | 2014 | Journal of Genetics and Genomics2014，41，4： | 0 |
| 9 | Targeting colorectal cancer using dietary flavonols显示文摘Colorectal cancer is among the well-known forms of cancer and a prominent cause of cancer demises worldwide.In vitro experiments reinforced by animal studies,as well as epidemiological studies of human colorectal cancer propose that the growth of this disease can be moderated by eating aspects.Dietary intake including green vegetables and fruits may result in the reduction of colon cancer chances.The finding suggests that the combinations of dietary nutrients may deliver additive or synergistic effects and might be a powerful method to avoid or eradicate colon cancer beginning and/or development.Flavonols are one of the most widespread dietary nutrients of the polyphenols-flavonoids and major constituent of Allium and Brassicaceae vegetables.Flavonols present in vegetables of Allium and Brassicaceae family are kaempferol,myricetin,quercetin,and isorhamnetin.These flavonols are claimed to have antiproliferative activity in vivo and in vitro against colorectal cancer.The objective of this review is to summarize the role of flavonols obtained from dietary sources in the prevention and treatment of colorectal cancer. | Nitin Dubey Nidhi Dubey Upendra Bhadoria Kamal Shah Nagendra Singh Chauhan | 2024 | Cancer Innovation2024，3，1： | 0 |
